herein by reference for all purposes.
TECHNICAL FIELD
[0002] The disclosure relates to an illumination device, and more
particularly to an illumination device attached to a computing
device, especially a handheld computing device such as a smart
phone, to facilitate video calls, teleconferences, other
camera-related processes, and other applications conducted with the
computing device requiring optimized illumination.
BACKGROUND
[0003] Computing devices, especially handheld computing devices,
have undergone explosive development in the past two decades. Here,
computing devices refer to but are not limited to: desktop
computers, laptop computers, and handheld computing devices such as
but not limited to smart phones such as iPhones.RTM. or
Android.RTM. phones, computing tablets such as iPad.RTM., Personal
Data Assistants (PDAs), and other devices that are relatively small
and light and are equipped with basic computing and internet
connecting capabilities. Computing devices are playing more and
more significant roles in people's work, entertainment, and
communications.
[0004] Most of the computing devices nowadays are equipped with
cameras. In many cases, especially for handheld computing devices,
there are two cameras, one on the front side of the device--the
same side with a general display screen, and the other one on the
back side. One fairly widespread usage of the computing devices is
video call, or video conference in some instances, during which
both video images and audio signals are transmitted and received.
Most likely the video images are captured with the front side
camera, allowing a user of the device to see the display on the
device and be visible at the same time. Video calls enable the
callers to hear and see the other person at the same time. Combined
with the mobile capacity of the handheld computing devices, video
calls strongly facilitate communication and interaction between the
parties.
[0005] One drawback of the video call conducted on a computing
device, however, is the unpredictable and often far-from-ideal
illumination, which renders the video call less attractive or even
impossible to proceed. This problem is especially acute for the
handheld computing devices. Due to their mobility, video calls
conducted with handheld computing devices may be carried out in
some locations never been conceived previously. Instead of a nicely
illuminated conference room, a user of a handheld computing device
may find himself/herself in a car, in a dark room, or in some
places with weak or impossible-to-adjust light, making it
impossible to show the user's image properly. The current
disclosure addresses this problem by providing an illumination
device that may be attached to a computing device and enable a user
to have manageable light for his/her video call or video
conference. In addition, the illumination device introduced by the
current disclosure may have numerous additional applications that
would provide significant convenience and greatly improve the user
experience of the computing device.

[0019] As indicated above, "computing device" used here is a broad
concept and it refers to but is not limited to: a desktop computer,
a laptop computer, and a handheld computing device such as but not
limited to smart phones such as iPhone.RTM. or Android.RTM. phones,
computing tablets such as iPadO, personal data assistants (PDAs),
and other devices that are relatively small and light and are
equipped with basic computing and network connecting capabilities.
Since the usage of the present disclosure is more clearly
demonstrated on handheld computing devices, the discussions will be
focusing on such devices. However, it should be clear that the
illumination device disclosed here may also be implemented to
desktop and laptop computers and have significant beneficial
effects.
[0020] With the implementation of front and back cameras, handheld
computing devices may be used in ways that could not be conceived
before. As indicated above, one of the applications is video call
or video conference that allows the users to see and speak to one
another at the same time. In most cases, a user is holding the
handheld computing device with the front of the handheld computing
device, defined as the side having a display screen, facing the
user. The front camera, the camera on the same side as the display
screen, is thus capable of capturing the image of the user,
especially the image of the user's face. Through its networking
capacities, the handheld computing device transfers the captured
image, as well as audio signals recorded, to the other
party/parties engaged in the video call or video conference.
[0021] Such a communication experience, however, may be spoiled by
weak or improper lighting. When it is too dark, it is very
difficult for the front camera to capture a usable image of the
user, making a video call less attractive. Moreover, many other
camera-related processes and applications conducted with a handheld
computing device may have similar requirements for optimized
lighting conditions. One simple example is taking a photograph or
video recording with the handheld computing device, either of the
user himself/herself, or of another person, or of any other scene
or subject. When the ambient light is too weak, it may ruin the
results of the picture or the video. Another example is the
"mirror" application for handheld computing devices, with which a
user may see his/her own image in the display. Poor ambient light
conditions also harm the usage of such applications.
[0022] The current device addresses the problems listed above by
attaching a light source, preferably a plurality of light-emitting
diodes (LEDs) to the handheld computing device, allowing the light
source to illuminate the user, especially the user's face, enabling
the front camera or the back camera to capture an optimized image
of the user or any other subject and facilitate the video call, the
photo or video capturing, the "mirror" application, or any other
camera-related experience.
[0023] Moreover, with the basic design, there may be numerous
variations that would provide different kinds of embodiments of the
illumination device to satisfy different needs for applications and
users. Some of the applications do not even have to be
camera-related because the illumination device disclosed herein may
also have signaling capacities besides the functions to provide
lighting.
[0024] The light source, as suggested, is preferably LED lights.
However, the light source may also be other lights such as compact
fluorescent lights (CFL) or electroluminescent light. In
particular, electroluminescent light using algae-based wire and
panels, such as the light based on RILI technology, may be
incorporated as the light source in the current device. In
addition, sometimes it is desirable to make the lights adjustable
in terms of luminous intensity, viewing angles, and diffusion. The
lights may have color either by using color lights or with the
addition of a color cover. In general, implementing more
adjustability may allow the illumination device to provide lighting
for one or more persons and for various purposes. It may also
enable the illumination device to flash, to demonstrate different
patterns, and therefore satisfy different needs.
[0025] There may be a power source, separate from the power source
for the handheld computing device. The power source may be
connected to the lights through a power connector, providing energy
needed for the illumination. The power source may be one or more
batteries, such as the regular AAA zinc-carbon or alkaline battery,
or any other type or size that may fit the needs in terms of energy
needs or physical accommodation. The battery may be disposable or
rechargeable, allowing flexibility as to cost-effectiveness and
convenience. The battery may be connected to both the illumination
device and the handheld computing device, providing energy to both
devices, serving as a backup or extra power source to the handheld
computing device. On the other hand, it is also possible to simply
connect the light source to the handheld computing device and allow
the light source to use the power of the handheld computing device,
reducing the size and weight of the illumination device and making
it more portable.
[0026] The illumination device includes an attachment assembly that
affixes the light source to the handheld computing device. The
attachment is preferred to be non-permanent, so that the lights may
be added or removed as the user desires. The attachment assembly
may take many forms. For example, it may be a flat case with an
indentation to enclose a power source and power connector, while
also having a recess or docking place for the handheld computing
device to attach. The current disclosure encompasses all kinds of
attachment assemblies that allow convenient connection between the
lights and the handheld computing device. Moreover, the attachment
assembly may serve additional purposes such as supporting the
handheld computing device in an easy-to-view position, allowing a
user of the handheld computing device to watch the device in a
hand-free mode. In addition, more complex attachment assembly may
include structures that allow the illumination device to be further
integrated with the handheld computing device in terms of
synergetic control and data sharing.
[0027] The illumination device may further comprise an external
switch that allows the user to turn the lights on and off. However,
it is possible, especially when the illumination device is
sufficiently integrated with the handheld computing device, to use
the buttons, switches, and menus on the handheld computing device
to control the lights.
[0028] As indicated above, the illumination device may be used to
facilitate video calls or video conferences or to enhance other
camera related functions of the handheld computing device. In such
a case, the illumination device taught by the current disclosure
may enhance such experiences by providing additional and
well-controlled illumination.
[0029] In addition, with further connection between the lights and
the handheld computing device, the lights of the illumination
device may serve as indicators for a handheld computing device's
status or as signals for the applications being used on the
handheld computing device. For example, the lights may flash or
light up when there is an incoming call. Or the lights may change
in lighting pattern, luminous intensity, or color when the user is
speaking on the handheld computing device or when certain music or

[0030] Also in the purview of the current disclosure is a series of
computer programs or applications that may be used to control the
illumination device. For example, a basic version of such a program
would be able to adjust the luminous intensity, viewing angles,
lighting pattern, and/or color of the illumination device. A more
advanced program would allow the illumination device to synergize
with the status of the handheld computing device, such as an
incoming phone call. Still another advanced program may integrate
the illumination device with another application so that the lights
are partially controlled by the application.
[0031] In general, the illumination device is designed to be small,
portable, versatile, energy efficient, durable, and fully
compatible with the handheld computing device, or more generally,
the computing device, that is to be used with the illumination
device.

integral to a handheld computing device to which the illumination
device is attached.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
[0112] The preferred embodiments of the present disclosure will now
be described with reference to the drawings. Identical elements in
the various figures are identified with the same reference
numerals.
[0113] Reference will now be made in detail to embodiment of the
present disclosure. Such embodiments are provided by way of
explanation of the present disclosure, which is not intended to be
limited thereto. In fact, those of ordinary skill in the art may
appreciate upon reading the present specification and viewing the
present drawings that various modifications and variations can be
made thereto.
[0114] FIG. 1 is an isometric drawing of a front view of a first
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. Shown in FIG. 1 are the
illumination device 1 attached to the handheld computing device
100, wherein the illumination device 1 comprises an attachment
assembly, which here manifests itself as a case 55, a power source
30, a dock 60 for the handheld computing device 100, an
illumination device switch 70, and a light source comprising a
plurality of LEDs. For clarity purposes, not all the LEDs are
marked in FIG. 1. Shown in FIG. 1 is also the handheld computing
device 100 having a display screen 130 defining a front side 110,
an ON button 170, an OFF button 180, a MENU switch 190, and a front
camera 120. Also shown in FIG. 1 is an image 140 being displayed in
the display screen 130.
[0115] As indicated above, the handheld computing device 100 is
defined broadly. In FIG. 1, the handheld computing device 100 is
shown as a smart phone having a display screen 130, an ON button
170, an OFF button 180, and a MENU switch 190. However, it should
be clear that the current disclosure may be used to accommodate any
computing device by making certain adjustments to the power source
30, the case 55 and the dock 60. Moreover, the format and
configuration of the handheld computing device 100 may vary
significantly due to the brand and version of the device. It is
very likely that a handheld computing device 100 does not have any
of the buttons or switches shown in FIG. 1. Nevertheless, it should
be clear that the current disclosure provides an illumination
device 1 that may accommodate all kinds of computing devices,
especially handheld computing devices.
[0116] The image 140 here in FIG. 1 is shown to demonstrate
possible display on the screen when the handheld computing device
is in use. The image 140 may be the image of a party engaged in a
video call or video conference with the user of the handheld
computing device. The image 140 may also be the image of the user
of the handheld computing device when a photograph or video is
being captured by the front camera. When it is the image of the
user of the handheld computing device, the user may view the image
and adjust the luminous intensity, viewing angles, color, and
lighting pattern of the light source 10 to achieve optimized
result. The user may also adjust the distance from the handheld
computing device 100. The illumination of user with the device will
work best when the proper distance from camera to user is achieved.
The image 140 may also be the image of any person or subject being
captured by a camera other than the front camera. Furthermore, the
image 140 may also serve as an illustration of any picture or image
that are displayed on the screen 130.
[0117] The LEDs, as shown in FIG. 1, are the preferred type of
light source 10. As indicated above, it is still possible to use
other kinds of light, such as CFL or electroluminescent light, as
the light source 10. The basic features of the LEDs may vary
according the specific needs of the user and the specific usage for
the illumination device 1. For example, the LEDs' luminous
intensity, viewing angle, and color may be different from model to
model. It is possible to use LED emitting white light or color
lights. It is also possible to use color covers or films to enable
a white-light LED to show color. Preferably, a plurality of LEDs
are used as the light source 10, as shown in FIG. 1. However, it is
possible to use only one light. The LEDs may be controlled
individually or as a whole regarding switching them on or off, or
regarding the luminous intensity, viewing angle, and color of the
LEDs. Alternatively, the LEDs may be arranged into subsections that
may be controlled as individual subsections. For example, as in
FIG. 1, the LEDs may be arranged into three subsections: the left
four LEDs, the right four LEDs, and the top two LEDs. As a user of
the handheld computing device 100 desires, he/she may choose to
turn on and off any subsection or change the features of any
subsection according to the ambient light conditions, the posture
of the user, and/or the application or process involved.
[0118] The LEDs may have different technical specifications and
dimensions. In general, the LEDs should be small and match the
handheld computing device 100 and the intended usage. Standard T1
LEDs, T1-3/4 LEDs, various kinds of surface mount LEDs, miniature
LEDs, mid-range LEDs, high-power LEDs, LED panels, LED modules, and
other kinds of LEDs may all be possible choices for specific uses.
Some special types of LEDs may be used for special effects.
[0119] For example, single wave length LEDs may be used to light
therapy. In general, the LEDs may use electricity ranging from 0.1
mW to 50 W, with current ranging from 0.1 .mu.A to 1 A and voltage
ranging from 0.1 mV to 250 V. The LEDs may emit white light or
color light with particular wavelengths. In a preferred embodiment,
the LEDs emit light of warm color temperature, i.e. 2400
Kelvin.
[0120] The power source 30 here in FIG. 1 is not an indispensable
component of the illumination device 1. In some situations, it is
preferable to have a power source 30 as shown in FIG. 1. However,
in other situations, having a power source presents different
advantages. For example, when the illumination device 1 is equipped
with a connector to the internal power source of the handheld
computing device 100, it is possible for the illumination device 1
to share the power source with the handheld computing device 100,
making the structure of the illumination device 1 less complicated
and easier to control. However, when it is desirable to have a long
battery life or to have a changeable illumination device 1 that may
fit different kinds of handheld computing device 100, it is
probably advantageous to have an power source, like the power
source 30 shown in FIG. 1, because the power connector may not fit
with all the different handheld computing devices.
[0121] In FIG. 1, the power source 30 may be a battery. However, it
may well be other kinds of power sources as long as the light
source 10 is provided with energy. If a battery is used, the power
source 30 may be a disposable battery or a rechargeable battery,
addressing different concerns such as cost and convenience. In
terms of chemical composition, many kinds of batteries may be used.
The types of batteries to be used as the power source 30 include
but are not limited to: zinc-carbon batteries, alkaline batteries,
aluminum batteries, dry-cell batteries, lead-acid batteries,
lithium batteries, nickel batteries, potassium batteries, and
sodium-ion batteries.
[0122] The power source 30 is designed to provide power to the
LEDs. When the voltage or current provided by the power source 30
is insufficient to power the LEDs, it is possible to include a
regulator circuit, such as a buck-boost converter, to enhance the
output from the power source and ensure that the LEDs are
adequately supplied. Such regulator circuits are well-known in the
arts. In addition, the illumination device 1 may further comprise a
battery meter that measures the battery life and informs the user
to change batteries when necessary. The technology for such battery
meter is also well known in the arts.
[0123] In addition to providing power to the LEDs, the power source
30 may serve as a backup power source to the handheld computing
device 100. With proper connections between the handheld computing
device 100 and the illumination device 1, both in terms of control
circuitry and electricity connections, it is possible that the
power source 30 may be used to directly provide energy to the
handheld computing device 100, enabling a longer overall battery
life and providing more flexibility. When the power source 30 is
rechargeable, the handheld computer device 100 may also be
recharged, enabling a convenient solution for supplying power to
both the illumination device 1 and the handheld computing device
100.
[0124] It should be noted that FIG. 1 is only supposed to be
illustrative as to the position and arrangement of the case 55 and
the power source 30. The power source 30 may be located at other
positions. For example, the power source 30 may be shield in a
chamber attached to the back of the case 55.
[0125] In FIG. 1, an illumination device switch 70 is also shown.
Such an external switch, as a power source 30, is not an
indispensable part of the illumination device 1. If the
illumination device 1 is sufficiently integrated with the handheld
computing device 100, it is possible to control all aspects of the
LEDs through the buttons, menus, and switches of the handheld
computing device 100. Such a design may also provide a full
spectrum of options as to the individual, sub-sectional, or whole
group of LEDs' luminous intensity, viewing angle, color, and
lighting patterns. However, in certain situations, having an
external switch may be desirable because it affords a quick and
easily accessible control for the lights.
[0126] It should be noted that the switch 70 may have different
designs to accommodate different needs. The switch 70 may be
mechanical, electrical or logical. In its most simple form, switch
70 may turn on and off all the LEDs without any other adjusting
capacities. However, switch 70 may also be designed as a dimmer
that dictates the brightness, or luminous intensity of the LEDs in
a certain range. One possible design is that the switch 70 may
control mechanical means of adjustment such as articulating lens or
lenses covering the LEDs, allowing for change of illumination
intensity. To enable the switch 70 to perform such a function, some
well know circuits such as a potentiometer may be included in the
illumination device. Moreover, switch 70 may have a more complex
design to control the individual, sub-sectional, or whole group of
LEDs' luminous intensity, viewing angle, color, and lighting
patterns.
[0127] The current disclosure discloses an attachment assembly that
affixes a light source 10 to a computing device. In the embodiment
shown in FIG. 1, while the computing device is a handheld computing
device 100, the attachment assembly is a case 55 having a recess
that partially encases the handheld computing device 100, leaving
the front side 110 largely exposed so that the display screen 130
may be viewed clearly and the front camera 120 may be unblocked.
The handheld computing device 100 is snapped in the recess of the
case 55. The LEDs are mounted on the edges of the case 55 to direct
light from the LEDs in a generally perpendicular direction to the
front side 110 of the handheld computing device 100.
[0128] The case 55 may be a one-piece structure or have a
multi-piece design for more flexibility and convenience. In
addition to attaching the light source 10 to the handheld computing
device 100, the case 55 may also provide physical and hygienic
protection to the handheld computing device 100, preventing it from
damages due to physical impact. The case 55 may be made from
materials such as but not limited to: rubber, leather, faux
leather, wood, marble, artificial stone (e.g., Silestone.RTM.),
graphite (e.g., carbon fiber), metal (e.g., aluminum) sheet or
foil, or plastic such as, but not limited to, polyethylene
terephthalate (PET), polyethylene (PE), high-density polyethylene,
polyvinyl chloride (PVC), polyvinylidene chloride (PVDC),
low-density polyethylene (LDPE), polypropylene (PP), polystyrene
(PS), high impact polystyrene (HIPS) and polycarbonate (PC), or
some combination thereof. The case 55 may be made of one kind of
materials, or different parts of the case 55 may be made of
different materials, ensuring optimized protection and feel. In
some examples, case 55 may be designed to be flexible. In some
examples, case 55 may include light source(s) 10 comprising one or
more flexible LED strips, a flexible printed circuit board and/or a
flexible power source (such as a flexible battery).
[0129] It should be noted that the "snap-in" design is not the only
form of attachment to connect the handheld computing device 100 to
the case 55. For example, the case 55 may comprise two pieces of
cover, either or both may be slidably connected to the handheld
computing device 100. It is also possible that the handheld
computing device 100 may be fastened to the case with other means
such as pre-positions screws, hook-and-loop fastener, riveting, or
any other kind of mechanisms allowing a secure attachment.
Preferably, the case 55 is removably attached to the handheld
computing device 100, allowing easy detaching for higher level of
flexibility. However, it would also be acceptable to make the case
55 a permanent fixture of the handheld computing device 100,
allowing high level of integration between the handheld computing
device 100 and the illumination device 1.
[0130] The LEDs may be mounted to the case 55 by any means that
allow secure attachment. The LEDs may be welded, screwed, riveted,
glued, co-molded, or in any other way linked to or inserted into
the case 55. Necessary structures, such as prepositioned magnets or
hook-and-loop fasteners, or snaps, may be employed to fasten the
LEDs to the case 55. In general, the LEDs may be connected to the
case 55 in a permanent or removable manner. Moreover, the approach
to connect the LEDs to the case may vary due to the type of LEDs or
the type of cases used.
[0131] After attachment, the relative positions and the projection
angles of the LEDs may still be adjustable, allowing more
flexibility as to the area, scope, and depth of illumination.
Moreover, the attachment method for the LEDs may be designed in
such a way that allows the LEDs to illuminate to a direction not
generally perpendicular to the front side the handheld computing
device. For example, each LEDs may be mounted on the case with a
universal wheel that allows the LED to tilt to all directions.
Thus, when it is desirable to use the LEDs with the back camera of
the handheld computing device, such designs may allow the LEDs to
illuminate in the direction of the back camera.
[0132] As indicated above, the attachment assembly may take other
forms apart from a case 55. The key is to enable the attachment
assembly to attach the light source 10 to the handheld computing
device. In the simplest format, the light source 10 may be mounted
directly on the handheld computing device, making the light source
10 integral to the handheld computing device. In that case, the
attachment assembly may simply comprise the minimum material or
structure, such as the magnet, glue, screw, rivet, or welding
material that connects the light source 10 to the handheld
computing device. In a more complex form, the attachment assembly
may comprise simply of one or more attachment strips that have the
LEDs mounted on the strips and these strips may be attached to the
handheld computing device through any means possible. The strips
may be connected to the handheld computing device with screws or
hinges, allowing the strips to tilt away from the handheld
computing device while maintaining the attachment, enabling the
LEDs to illuminate a wider area. When necessary, the LEDs may even
be removed from the handheld computing device and the attachment
assembly may comprise an extension cord that allow the LEDs to be
powered, controlled, and provide illumination to an extended area.
Such a design may be helpful to maximize the illumination scope of
the illumination device.
[0133] The illumination device 1 may further comprise a sensor that
detects and measures ambient light conditions. The general
structure and circuitry for such sensor is well known in the arts.
An ambient light sensor (see FIG. 7) may facilitate the adjustment
process for the luminous intensity, viewing angle, color, and
lighting pattern of the handheld computing device, making it
possible for automatic control when an applicable computer program
is installed.
[0134] FIG. 2 is an isometric drawing of a side view of the first
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. To make the various
elements visible, dotted lines are used to illustrate structures
that are shielded from view by the case 55. Shown in FIG. 2 is the
illumination device 1 having a case 55, a power source 30, a dock
60, a plurality of LEDs covered by light covers 20, and power
connector 40 connecting the LEDs to the power source 30. Also shown
in FIG. 2 is the handheld computing device 100 being encased in the
case 55. For clarity purposes, not all the LEDs or light covers are
marked in FIG. 2.
[0135] The power connector 40 represents a means to connect the
LEDs to a power source, such as the power source 30 shown in FIG.
2. As indicated above, the power source 30 may be a battery or any
other kind of power source that is compact and safe. The power
connector 40 may be regular electric wiring that is well-known in
the arts or any other kinds of circuitry that may be used to
connect a light source 10 to a power supply.
[0136] The dock 60 may be considered a part of the attachment
assembly, together with the case. Like the power connector 40, the
dock 60 is not an indispensable structure of the illumination
device. However, the dock 60 may play some important roles if it is
present. The dock 60 may serve as part of the "snap-in" structure
that secures the handheld computing device 100 in the case 55. More
importantly, the dock 60 may include connectors that may be plugged
into the handheld computing device 100 and serve to integrate the
illumination device 1 with the handheld computing device in terms
of data sharing, synergistic control, and sharing of power sources.
The technology to enable the dock 60 to serve as a connector to the
handheld computing device 100 is well known in the arts.
[0137] The light covers 20 may be a lens used to diffuse the light
from the LEDs, focus the lights from the LEDs, and/or add certain
colors when the LED light is white. The light cover 20 may diffuse
and soften the light from the LEDs and help to achieve optimal
illumination without creating a blind effect.
[0138] The light cover 20 may be any kind of diffuser, such as but
not limited to: polycarbonate LED diffuser, acrylic LED diffuser,
clear LED diffuser, opal LED diffuser, satin LED diffuser, LED
diffuser films, or any product or material having LED light
diffusing capability. The light covers 20 may also be any kind of
lens that is adjustable or unadjustable. The light covers 20 may be
colored, changing white light emitted by the LEDs to color
lights.
[0139] The light covers 20 may be attached to the LEDs or to the
case. The manner of attachment may vary according to the materials
used and the specific configuration of the different structures.
The light covers 20 may be slidable or rolling covers that may be
attached or detached easily. The light covers 20 also be glued,
screwed, welded, or riveted to the LEDs or the attachment
assembly.
[0140] The configuration of the light covers 20 may differ from
what is shown in FIG. 2. For example, the light covers 20 may take
the form of "light strip" or a "light pipe," which may cover more
than one LED light. In particular, one "light pipe" may cover the
left four LEDs, another one for the right four LEDs, and another
for the two LEDs on top, enabling better diffusion and better
illumination. Alternatively, a continuous "light strip" or "light
pipe" may cover all the LED lights.
[0141] FIG. 3 is an isometric drawing of a back view of the first
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. Shown in FIG. 3 are the
case 55, the LEDs, and the handheld computing device 100 having a
back side 115 and a back camera 125 on the back side 115.
[0142] As indicated above, the attachment assembly may take many
forms. The case 55 here is one example that allows both light
source 10 attachment and general protection to the handheld
computing device. Certain methods to mount the light source 10 to
the case may allow the light source 10, preferably LEDs, to be
adjustable in position and used with the back camera 125. In such
circumstances, the LEDs may assist the photo or video capturing
process or other applications conducted with the back camera.
[0143] The attachment assembly may also comprise other structures
that may be combined with the case 55. One possible addition is a
hand-free structure such as but not limited to a frame stand and/or
a hanger. The frame stand or hanger is preferably foldable and may
attach to the back of the case 55, occupying little space with
folded. When the frame stand or hanger is unfolded, it may support
or hang the handheld computing device in an upright position,
allowing the display to be viewed comfortably by a user without
occupying a user's hand. More particularly, the side(s) and bottom
edge of the case may be able to be made with an angled surface so
that the case may serve as part of a stand. For example, the
thicker bottom area in a case, adjacent to where the external
battery is installed, may provide enough surface to support an
IPhone.RTM. at an angle. In summary, the frame stand or hanger
enables hand-free viewing of the handheld computing device,
providing more flexibility as to what can be done with the
device.
[0144] FIG. 4 is an isometric drawing of a front view of a second
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. Shown in FIG. 4 are the
illumination device 1 attached to a handheld computing device 100,
wherein the illumination device 1 comprises an attachment assembly,
which comprises a case 55 and a dock 60, and a plurality of LEDs.
For clarity purposes, not all the LEDs are marked in FIG. 4. Shown
in FIG. 4 is also the handheld computing device 100 having a
display screen 130 defining a front side 110, an ON button 170, an
OFF button 180, a MENU switch 190, and a front camera 120. Also
shown in FIG. 4 is an image 140 being displayed in the display
screen 130.
[0145] FIG. 5 is an isometric drawing of a side view of the second
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. To make the various
elements visible, dotted lines are used to illustrate structures
that are shielded from view by the case 55. Shown in FIG. 5 is the
illumination device 1 having a case 55 and a dock 60, a plurality
of LEDs covered by light covers 20, and a power connector 40. Also
shown in FIG. 5 is the handheld computing device 100 being encased
in the case 55. For clarity purposes, not all the LEDs or light
covers are marked in FIG. 5.
[0146] FIG. 4 and FIG. 5 illustrate a second embodiment of the
current disclosure. In this embodiment, the power source and the
switch shown in FIG. 1-2 are no longer present. The light source
10, here a plurality of LEDs, is connected by the power connector
40 to the internal power source of the handheld computing device
100. Moreover, with further integration of the illumination device
1 and the handheld computing device 100, the luminous intensity,
viewing angle, color, and light pattern of the light source 10 may
be adjusted by the switches, buttons, and menus of the handheld
computing device, eliminating the need for an external control
switch. Such a design simplifies the basic structure of the
illumination device 1, yet requiring higher level of connection and
synergy between the illumination device 1 and the handheld
computing device.
[0147] It should be noted that the second and third embodiments may
not necessarily be described to the fullest extent because such
descriptions are provided for the first embodiment. In particular,
the description for any of the embodiments should be considered
included other embodiments as long as there is not conflict between
the descriptions.
[0148] FIG. 6 is an isometric drawing of a front view of a third
embodiment of the present disclosure when an illumination device is
connected to a handheld computing device. Shown in FIG. 6 are the
illumination device 1 attached to the handheld computing device
100, wherein the illumination device 1 comprises a light source 10
comprising a circular light panel 200 encircling a display screen
130. Shown in FIG. 6 is also the handheld computing device 100
having a display screen 130 defining a front side 110, a MENU
switch 190, and the front camera 120. Also shown in FIG. 6 is an
image 140 being displayed in the display screen 130.
[0149] In the third embodiment, some other features such as the
attachment assembly, the power source 30, the dock 60, and the
illumination device switch 70 are not displayed. However, it should
be noted that these structures may still be present but shielded
from direct view. As indicated above, electroluminescent light
using algae-based wire and panels, such as the light based on RiLi
technology (produced by Revolution in Lighting, Inc.), may be used
as the light source 10. The design of the circular light panel 200
is particularly suitable to use such lighting technology, which is
in general energy efficient, long lasting, bright, and having a
wide viewing angle. The circular light panel 200 is preferably thin
and may attach to the handheld computing device 200 using an
attachment assembly comprising any kind of connecting mechanism,
such as industrial glue. It should also be noted that the design,
size, and shape of the light panel 200 may vary according to
functional and/or aesthetic needs. The power supply, the control
system, and the possible varying display of lighting by the light
source 10 are fully described above and below.
[0150] Referring now to FIGS. 7 and 8, there is another embodiment
of the present disclosure as shown from the front and back,
respectively. The illumination device 1 takes the form of a case 55
and is shown without a computing device 100 (see FIG. 15) attached
thereto. Generally, the embodiment has a front side 110, back side
115, top 105, bottom 95, and at least two side surfaces 90. Each of
these surfaces interact to generally define a recess 65 as shown in
FIG. 7.
[0151] Each of the side surfaces 90 has a generally horizontal
extension or light rail that extends past and from the front
surface 110. The light rails generally comprise a light cover 20
and a plurality of light sources or LEDs. The plurality of light
source 10 are preferably LEDs that emit white light. The white
light can be produced via mixed-color lighting or phosphor
conversion or any other suitable technology. In some instances, it
may be desirable to have the LEDs be capable of producing different
colors and/or differing shades of light and such LEDs may be
incorporated as appropriate. The light source 10 may be any type of
LEDs as previously described herein and are preferably surface
mounted LEDs or may alternatively be any other suitable type of
light source, such as, without limitation incandescent,
fluorescent, or high-intensity discharge (HID) bulbs.
[0152] The light covers 20, here, are coverings for the LEDs. The
light covers 20 may cover, but not touch, each light source 10
individually or cover a number of light source 10 simultaneously.
In other embodiments, the light covers 20 may cover, and touch, any
one or more light sources 10. The light covers 20 are preferably
translucent, and in some cases transparent, plastic coverings that
serve to diffuse the light as it passes through these coverings.
The light coverings 20 may be removable and may comprise different
materials and colors to provide a particular degree of diffusion or
a tint, shade, or other color distortion or any combination thereof
to the light source 10. In other embodiments, the light covers 20
are permanently attached thereto.
[0153] Further, each of the light covers 20 are designed to permit
light to be emitted outwards from the illumination device 1 along
at least a 180.degree. arc. This is due to the fact the light
covers 20 are generally shaped to cover the area above the light
source 10 and on each side of the light source 10 to the point at
which the light source 10 terminate at the device. In some
instances, the light covers 20 may further be disposed past the
point of termination of the light source 10 and may allow for rear
facing light source 10 using the same principles as the front
facing light sources described herein.
[0154] The light covers 20 are preferably disposed along the length
of the side surface(s) 90 but may fully encircle the case 55. The
light covers 20 may also be intermittent with gaps or spaces in
between a number of separate light covers. In a preferred
configuration, one light rail is longer than the other light rail
(see FIG. 10). This serves to provide access to features of a
computing device, such as a smart phone, which are typically
disposed on the left-side of the device.
[0155] Where the light covers 20 intersect with the top area and
bottom area of the illumination device 1 a securement mechanism 75
is formed extending therefrom. This securement mechanism 75 may be
located in at least one corner area and up to four or more corner
areas. In a preferred embodiment, there are at least two securement
mechanisms 75. The securement mechanism 75 manifests itself as a
tab or extension that extends substantially perpendicularly from
the top of the light cover 20. Preferably, the securement
mechanisms 75 are disposed on opposite ends and opposite sides of
the illumination device 1. This enables, for example, one
securement mechanism to be disposed on the upper left side and the
other to be disposed on the lower right side. This disparity
provides the most secure arrangement of the two-form securement
mechanism. With three or more securement mechanisms, the
arrangement is less vital as the extra points of contact override
the necessity for a particular arrangement.
[0156] When a computing device is pushed downward into the recess
the securement mechanisms 75 slide over a surface of the computing
device thereby securing the position of and retaining the computing
device therein. In order to remove the computing device, the case
55 is flexed downwards (away from the computing device) slightly,
allowing the securement mechanisms 75 to withdraw or recede from
covering the computing device and the computing device is
subsequently removed.
[0157] Further features of the illumination device 1 include an
aperture 135 to provide unrestricted or uninhibited access for a
rear facing camera of the computing device. The position of the
aperture 135 can be varied to accommodate any number of sizes,
shapes, and positions. An ambient light sensor 145 may be disposed
thereon to automatically adjust the intensity of the light sources
10 in accordance with the ambient light. A charging port 85 enables
charging of the power source 30 (see FIG. 1) which is a
rechargeable power source and may be located within the
illumination device itself.
[0158] In addition, the illumination device 1 may provide for at
least one depressible or touch sensitive button 80. In a preferred
embodiment this button is located on the back side 115 of the
illumination device 1. The touch sensitive button 80 controls an
operative state of the light sources 10. This may include powering
the light sources 10 on or off as well as serving to dim or
intensify the light sources 10 as needed.
[0159] In order to dim or intensify the light sources 10 one would
depress and continue to apply pressure to or leave their finger
remaining over the button area. This action causes the light
sources 10 to either dim or intensify until the button is ceased to
have been engaged. Further engagement of the button 80 will result
in further dimming or intensifying based on the current setting of
the light sources 10.
[0160] In FIGS. 9-12, the embodiment shown in FIGS. 7-8 is further
shown from the right side, left side, top, and bottom,
respectively. Here, the overall, shape and structure of the
illumination device 1 is more apparent, as are the interactions
between the front side 110, back side 115, top 105, bottom 95, and
sides 90. The light sources 10 are shown from one configuration
arrangement.
[0161] There may be cutouts or voids 150 between areas of the light
rails where such voids or spaces 150 have been strategically placed
to enable interaction with the computing device once the computing
device has been secured thereto. As shown, such voids 150 are shown
along the top, bottom, and mid to upper left side of the case.
These positions are the typical locations of buttons and other
interactive features of computing devices, namely smart phones.
However, the exact arrangement, size, and shape of such voids 150
can be altered as necessary.
[0162] As shown in FIG. 12, the charging port 85 is typically
located in the bottom of the illumination device 1. The charging
port 85 may be any type of suitable port including those known in
the art such as a universal serial bus (USB) port, which provides
for both charging downstream ports and dedicated charging ports and
other suitable charging technology. The port is operably coupled to
the power source contained therein to charge it as required.
[0163] Referring now to FIG. 13, the light covers 20 have been
partially removed to expose the light sources 10 thereunder. This
arrangement and number of light sources 10 is one of but
innumerable such arrangements and is intended to be merely
representative of one such arrangement. It can also be seen how one
of the light rails (left light rail in this embodiment) contains
more light sources 10 and is longer in length than the other light
rail (right light rail in this embodiment). In other embodiments,
the configuration as to which is the longer light rail containing
more light sources 10 and which is the shorter light rail
containing fewer light sources 10 may be reversed. As should be
understood, the number of light sources on each rail and the length
of each rail may be varied as may be desired in order to contain
any number and/or arrangement of light sources 10 on each rail, and
the length of each rail may also be varied so as to be longer or
shorter in length, as desired.
[0164] FIG. 14 demonstrates an iteration of the present disclosure
as shown from a cutaway sectional view from the view in FIG. 12. As
shown, there is generally a front side 110, a back side 115, and a
side surface 90 which service to form the recess 65 for receiving a
computing device. Emanating or rising from the front side 110 is
the light covers 20. The light covers 20, as shown, as generally as
an inverted "u"-shaped but may bear a more rounded "c" or other
shape depending on the light source 10 used and the preferences for
diffusing that light source 10.
[0165] The light covers 20 are generally unitary, single channels
that run along either side, or top or bottom of the front side 110.
The light covers 20 may be disposed separately or may be connected
forming a continuous cover traveling the length of the perimeter.
In some embodiments the light covers 20 may be oriented to be
positioned along the back side 115 as well. The light covers 20, as
previously noted, are configured to diffuse light. Such diffusion
may be accomplished by use of certain materials, textures,
patterns, or the like or any combination thereof comprising the
light covers 20. For example, denser materials are typically more
efficient in diffusing light and such a material may be required
with more luminous light sources.
[0166] Internally, a printed circuit board (PCB) 160 is shown with
a rechargeable power source 30 coupled thereto. Power connectors
40, such as wiring, couples the light sources 10 to the power
source. The depressible button 80 can function to alter an
operative state of the light sources 10 including to turn light
sources on/off as well as change the luminous output of the light
sources 10.
[0167] In FIG. 15, the illumination device 1 is shown from a
perspective view with the computing device 100 removably coupled
thereto. The computing device 100 has a display screen 130, front
facing camera 120, and computing device controls 155, and other not
explicitly named features. By partially surrounding the computing
device with diffused light from the light sources 10 and light
covers 20, the present disclosure enables even and consistent
lighting across a subject thereby creating desirable captures of
static and time varying images as further described herein.
[0168] Further, as shown in FIG. 15, the light sources 10 are
positioned equidistant from one another. The spacing or gap between
these light sources 10 may vary but is preferably about 0.1 inch to
about 2 inches, and more preferably about 0.25 inches. The gap or
spacing being defined as the area where the placement of one light
source ends and another begins. The light sources 10 may reside on
a strip that operably couples each light to one another or may
otherwise reside directly on the printed circuit board as
described. Other functional implementations may also be employed
and are covered under the purview of this disclosure.
[0169] In some instances, the general concept described herein in
FIGS. 7-14 may be capable of being used with a rear facing camera
as well. In such an embodiment, the orientation of the light rails
including the light sources and light covers would be rear facing
instead of forward facing. The recess, securement mechanisms,
apertures, and the like would relatively stay in the same
orientation as with a forward-facing implementation. In some
embodiments, there may be both forward facing and rear facing light
rails containing light sources and light covers as described
herein. In such an embodiment, the light sources (forward facing
and rear facing) may be able to be independently controlled thus
enabling the rear facing light sources to be turned on/off as
necessary and enabling the same functionality to occur with the
forward-facing light sources.
[0170] As indicated above, it is in the purview of the current
disclosure, as described in the Figures, that a series of computer
applications or programs may accompany the illumination device
disclosed herein. These applications may facilitate the use of the
illumination device and ensure that it is safe, well-controlled,
and optimized to assist the use of some other applications.
However, it is of note that this is not a requirement, and, in
fact, it may be more practical to operate the present disclosure as
a standalone embodiment. This gives full control over the
illumination device 1 to the user. The user can couple the
illumination device 1 to a computing device 100 as needed.
[0171] Once coupled to the computing device 100, the user can
change the intensity or any other property of the light sources 10
by using controls, switches, and the like embedded with the
illumination device 1 itself. Further, this standalone usage is
enhanced by the rechargeable power source contained within the case
55. Thus, the power source may be recharged as necessary without
requiring the computing device 100 to be recharged, nor would it
drain a charge from the power source of the computing device.
[0172] Referring next to FIG. 16A-FIG. 24F, additional example
embodiments of illumination device 1 are described. It should be
noted that these embodiments may not necessarily be described to
the fullest extent because such descriptions are provided for in
the embodiments described above. In particular, the description for
any of the embodiments should be considered included in other
embodiments as long as there is not conflict between the
descriptions
[0173] As discussed above, the general concept described in FIGS.
7-14 may be capable of being used with a rear facing camera. Also,
in some embodiments, there may be both forward facing and rear
facing light rails containing light sources and light covers. FIG.
16A-FIG. 17D illustrate example arrangements of case 55 having both
forward facing and rear facing light rails containing respective
light sources 10, 210 and respective light covers 20, 220, which
may be used with both forward facing and rear facing cameras. The
type, arrangement, configuration, location and number of light
sources 10, 210 is one of but innumerable such arrangements and is
intended to be merely representative of one such arrangement. As
should be understood, the number of light sources 10, 210 on each
rail and the length of each rail may be varied as may be desired in
order to contain any type, configuration, location, number and/or
arrangement of light sources 10, 210 on each rail, and the length
of each rail may also be varied so as to be longer or shorter in
length, as desired.
[0174] Referring to FIGS. 16A-16F, an example embodiment is shown
of case 55 having front and rear facing light rails. In particular,
FIGS. 16A-16C illustrate respective back, front and perspective
views of the case 55 having front light rails (containing light
sources 10 and light covers 20) and rear facing light rails
(containing light sources 210 and light covers 220); FIGS. 16D and
16E illustrate cross-section views of the case 55 taken along lines
16D-16D of FIG. 16A, according to different example arrangements of
front and rear facing light rails; and FIG. 16F is a cross-section
view of the case 55 taken along lines 16F-16F of FIG. 16B,
illustrating electrical connections of components of the case
55.
[0175] The illumination device 1 takes the form of a case 55 and is
shown without the handheld computing device 100 attached thereto.
Generally, the embodiment has a front side 110, back side 115, top
105, bottom 95, and at least two side surfaces 90. The case 55
includes aperture 135 to provide unrestricted or uninhibited access
for a rear facing camera of the computing device 100. Each rear
light rail includes light sources 210 having light covers 220 that
are separately disposed over respective light sources 210. Each
front light rail includes light sources 10 having light covers 20
that are separately disposed over respective light sources 10.
[0176] Light sources 210 may be the same as light sources 10 except
that light sources 210 are arranged on the back side 115 of the
case 55. Light covers 220, similar to light covers 20, are
configured to diffuse light. Light covers 220 may be the same as
light covers 20 except that light covers 220 are disposed on back
light sources 210. In some examples, light sources 10 and 210 may
have the same light characteristic properties (e.g., producing the
same colors). In some examples light sources 10 and 210 may have
different light characteristic properties (e.g., producing
different colors and/or differing shades of light). In some
examples, light covers 20 and 220 may have the same properties
(e.g., same material, same color, same tint). In some examples
light covers 20 and 220 may have different properties (e.g.,
different material, different color, different tint). In some
examples, rear facing light rails (light sources 210 and light
covers 220) may be configured to provide more light and/or more
diffusion than front light rails (light sources 10 and light covers
20), such as to provide improved captured images of groups of
people with a back camera compared to "selfies" taken with a front
camera.
[0177] In some examples, the forward-facing light sources 10 and
rear facing light sources 210 may be independently controlled, such
as by touch sensitive button 80. Thus, rear facing light sources
210 may be turned on/off as necessary, and the case 55 may enable
the same functionality to occur for the rear facing light sources
210 as described herein with respect to the forward-facing light
sources 10.
[0178] In FIGS. 16A-16E, the light sources 10, 210 (and respective
light covers 20, 220) are illustrated as being disposed along the
length of the side surface(s) 90. In some examples, the light
sources 10, 210 (and respective light covers 20, 220) may fully
encircle the case 55. In some examples, the light sources 10, 210
(and respective light covers 20, 220) may also be disposed along a
length of the top 105 (as shown in FIG. 1) or may be disposed along
a length of the bottom 95 of case 55.
[0179] In some examples, the case 55 may include charging port 85,
as described above. In some examples, the case 55 may include an
external memory slot 222. The memory slot 222 may provide
uninhibited access to a memory card interface of the handheld
computing device 100. The memory slot 222 may be suitable for
accepting any suitable external memory card known in the art, such
as, but not limited to, a secure digital (SD) memory card.
[0180] Referring to FIGS. 16D and 16E, two example arrangements of
forward and rear facing light sources 10, 210 are shown. FIGS. 16D
and 16E also illustrate the arrangement of rear facing light covers
220 with respect to light sources 210. For convenience, light
covers 20 are not shown in FIGS. 16D and 16E. In FIG. 16D, forward
light sources 10 and rear facing light sources 210 are disposed on
PCB 260 such that light sources 10, 210 are aligned with each other
(across PCB 260). In FIG. 16E, forward light sources 10 and rear
facing light sources 210 are disposed on PCB 260 such that light
sources 10, 210 are staggered with each other (across PCB 260)
(i.e., not aligned). It is understood that FIGS. 16D and 16E
represent example forward and rear facing light source
arrangements, and that other arrangements are possible.
[0181] FIG. 16F demonstrates an example electronic connection
arrangement of some of the components of the case 55 shown in FIG.
16B (as well as the case shown in FIG. 17B). As shown, there is
generally a front side 110, a back side 115, and a side surface 90
which services to form a recess for receiving the computing device
100. Emanating or rising from the front side 110 is the light
covers 20. Emanating from the back side 115 is the rear facing
light covers 220.
[0182] Internally, the PCB 260 is shown with a rechargeable power
source 30 coupled thereto. Power connectors 40, such as wiring,
couples the forward-facing light sources 10 and the rear facing
light sources 210 to the power source 30. The depressible button 80
can function to alter an operative state of the forward and rear
facing light sources 10, 210, including, for example and without
limitation, to turn light sources 10, 210 on/off as well as change
the luminous output of the light sources 10, 210 (including
independent control forward and rear facing light sources 10,
210).
[0183] Referring to FIGS. 17A-17D, another example embodiment is
shown of case 55 having front and rear facing light rails. In
particular, FIGS. 17A and 17B illustrate respective back and front
views of the case 55 having front light rails (containing light
sources 10 and light covers 20) and rear facing light rails
(containing light sources 210 and light covers 220); and FIGS. 17C
and 17D illustrate cross-section views of the case 55 taken along
lines 17C-17C of FIG. 17A, according to different example
arrangements of front and rear facing light rails. For convenience,
light covers 20 are not shown in FIGS. 17C and 17D.
[0184] The case 55 shown in FIGS. 17A-17D is the same as the case
55 shown in FIGS. 16A-16E, except that the configuration of the
light covers 220 may differ from the light covers 220 shown in
FIGS. 16A-16E. In FIGS. 17A-17D, the rear facing light covers 220
may cover more than one light source. For example, the light covers
220 may take the form of a continuous "light strip" or a "light
pipe" (as described above with respect to light covers 20) which
may simultaneous cover all light sources 220 of the respective rear
light rail.
[0185] As discussed above, light sources 10 (210) may be mounted to
the case 55 by any means that allows secure attachment and may also
be designed in such a way that allows the light sources 10 (210) to
illuminate to a direction not generally perpendicular to the front
side 110 of the handheld computing device 100. FIG. 18A-FIG. 19D
illustrate example different mounting positions of the light
sources 10 in case 55. FIG. 18A-FIG. 19B illustrate example
side-surface-facing light sources 10. FIGS. 19C and 19D illustrate
example front-side-facing light sources 10. Although FIG. 18A-FIG.
19D illustrate examples of front facing light rails, it is
understood that the example design may also be applicable to rear
facing light rails and a combination of front and rear facing light
rails.
[0186] In particular, FIG. 18A is a cutaway view of case 55 taken
from the front side 110 with a portion thereof removed (including
the light covers 20) exposing the light sources 10 residing
therebelow; FIG. 18B is a cross-section view of case 55 shown in
FIG. 18A along lines 18B-18B; FIG. 18C is a cross-section view of
portion 18C shown in FIG. 18B; FIG. 19A is a cross-section view
along lines 18B-18B of the case 55 shown in FIG. 18A with the
portion included (i.e., including light covers 20); FIG. 19B is a
cross-section view of portion 19B shown in FIG. 19A; FIG. 19C is a
cross-section view taken from the bottom side of another case 55
(such as shown in FIG. 13); and FIG. 19D is a cross-section view of
portion 19D shown in FIG. 19C.
[0187] As shown in FIGS. 18A-18C, the case 55 may include light
sources 10 mounted on PCB boards 161. Each PCB board 161 may be
mounted to the case 55 parallel to side surface 90 (via attachment
to the back side 115), such that the PCB board 161 extends
perpendicular to front side 110. Light sources 10 may be mounted on
each PCB board 161, such that the light sources 10 (in an emitting
direction) face the side surface 90, thus forming
side-surface-facing light sources 10. As shown in FIGS. 19A and
19B, light 224 from light source 10 may be emitted through light
cover(s) 20 in a direction not generally perpendicular to front
side 110 of the case 55.
[0188] In contrast, in FIGS. 19C and 19B, light sources 10 may be
mounted on PCB board 163. Each PCB board 163 may be mounted to the
case 55 parallel to side surface 90 (via attachment to the side
surface 90), such that the PCB board 163 extends parallel to front
side 110. Light sources 10 may be mounted on each PCB board 163,
such that the light sources 10 (in an emitting direction) face the
front side 110, thus forming front-side-facing light sources 10. As
shown in FIGS. 19C and 19D, light 226 from light source 10 may be
emitted through light cover(s) 20 in a direction generally
perpendicular to front side 110 of the case 55.
[0189] In addition to allowing the light sources to generate light
224 in a direction away from perpendicular (relative to the front
side 110), as shown in FIG. 19B, side-surface-facing light sources
(shown in FIGS. 19A and 19B) may also allow the case 55 to be
formed with a more compact width profile (i.e., between side
surfaces 90) than the case 55 shown in FIG. 19C, because of the
perpendicular arrangement of PCB boards 161 to front side 110.
[0190] As discussed above, the case 55 may include power source 30
that is separate from the internal power source of the handheld
computing device 100. Referring next to FIGS. 20A and 20B, example
embodiments of case 55 having power source 30 are described. In
particular, FIGS. 20A and 20B are perspective view diagrams of case
55 taken from the back side 115 according to different example
embodiments. In FIGS. 20A and 20B, the case 55 is shown without the
handheld computing device 100 coupled to the case 55, for
convenience in describing aspects of powering the illumination
device 1. It is understood that FIGS. 20A and 20B represent example
embodiments illustrative as to the position and arrangement of the
case 55 and the power source 30. The power source 30 may be located
at other positions.
[0191] Referring to FIG. 20A, the case 55 may include power source
30 (also referred to as battery 30) disposed in a chamber (not
shown) of case 55 and secured by cover 242 attached to back side
115 of case 55. The case 55 may also include depressible or touch
sensitive light operation button 242, depressible or touch
sensitive charging button 244, charging port 248 and discharging
port 250. In some examples, the case may include charging indicator
246. In some examples, the case 55 may include external memory slot
222. In some examples, the case may include charging sensor
252.
[0192] In some examples, battery 30 may be permanently fixed in
case 55. In some examples, battery 30 may be removably disposed in
case 55. As discussed above, in some examples, battery 30 may be a
disposable battery or a rechargeable battery or any other power
source, such as solar.
[0193] Battery 30 may provide power to the light sources 10.
Battery 30 may also serve as a backup power source to the handheld
computing device 100. For example, with control circuitry and
electrical connections (such as via dock 60 shown in FIG. 1),
battery 30 may be used to directly provide energy to the handheld
computing device 100, enabling a longer overall battery life. When
the battery 30 is rechargeable, the handheld computer device 100
may also be recharged, enabling a convenient solution for supplying
power to both the illumination device 1 and the handheld computing
device 100.
[0194] In some examples, the case 55 may include depressible or
touch sensitive button 242 to control an operative state of the
light sources 10 (e.g., powering light sources 10 on or off,
changing a luminous output of light sources 10, viewing angle,
color, lighting patterns, etc.). The functions of button 242 may be
similar to touch sensitive button 80 and/or illumination device
switch 70 as described above.
[0195] In some examples, the case 55 may include depressible or
touch sensitive button 244 to control charging of the internal
power source of the handheld computing device 100 by the power
source 30. In some examples, button 244 may also control charging
of an external device by power source, via discharging port 250.
For example, depressing or touching button 244 may cycle through
preset operation states, such as charging battery 30 via charging
port 248, charging the internal power source of the handheld
computing device 100 via charging port 248, charging the internal
power source of the handheld computing device 100 via battery 30,
discharging the battery 30 to power an external port via
discharging port 250 and disabling charging/discharging of battery
30. In some examples, the functionality of button 244 may be
combined with the functionality of button 242 into a single
depressible or touch sensitive button.
[0196] In some examples, the case 55 may include charging indicator
246, such as a charging bar. Charging indicator 246 may include a
battery meter that measures the battery life of power source 30 and
may indicate the battery life remaining. Charging indicator 246 may
also indicate to the user to change batteries or recharge battery
30 when necessary.
[0197] In some examples, the case 55 may include dedicated charging
port 248, which may be operably coupled to power source 30 and the
internal power source of the handheld computing device 100. The
charging port 248 may be any type of suitable port including those
known in the art such as a USB port, which provides for charging
power source 30 and the internal power source of the handheld
computing device 100. In some examples, the case 55 may also be
configured to be wirelessly charged (also referred to as inductive
charging). For example, the charging port 248 of case 55 may
include an induction charger (having an induction coil) configured
to be inductively coupled to a charging station (having its own
induction coil), such as (without being limited to) a wireless
charging pad. The induction coils in the induction charger and the
charger stations may be inductively coupled to create an
alternating electromagnetic field. The alternating electromagnetic
field may be converted into an electric current by the induction
charger of the case 55, to charge power source 30. In some
examples, the induction charger may use resonant inductive
coupling. In some examples, charging port 248 may include an
induction charger in addition to a USB charging port. In some
examples, case 55 may be configured to be kinetically charged. For
example, case 55 may include a kinetic energy charger that may use
motion of case 55 (e.g., by the user) to charge power source 30. In
some examples, the kinetic charger of case 55 may also be
configured to charge the internal power source of the handheld
device 100.
[0198] In some examples, the case 55 may include dedicated
discharging port 250 (separate from charging port 248), which may
be operably coupled to power source 30. The discharging port 250
may be any type of suitable port including those known in the art
such as a USB port, which provides for charging a downstream port
(e.g., an external device) via power source 30.
[0199] In some examples, case 55 may include charging sensor 252
for controlling charging of the power source 30 and the internal
power source of the handheld computing device 100. For example,
charging sensor 252 may include suitable circuitry and electrical
connections to measure a battery life remaining for each of power
source 30 and the internal power source of the handheld computing
device 100. Depending on the measured remaining battery life,
charging sensor 252 may distribute energy received via charging
port 248 (and/or a kinetic charger) among one or more of power
source 30 or the internal power source, based on one or more
predetermined conditions (such as prioritization of computing
device charging over power source 30 charging). For example,
charging sensor 252 may permit power source 30 to receive energy
when there is greater than 80% internal battery life remaining. In
contrast, charging sensor 252 may distribute energy to the internal
battery when there is less than a certain percentage of internal
battery life remaining, such as 20% internal battery life
remaining. The one or more predetermined conditions for charging
power source 30 and the internal battery may be preset by the
illumination device 1 and/or may be selected by the user.
[0200] Referring to FIG. 20B, the case 55 may include power source
30 (also referred to as battery 30) disposed in a chamber (not
shown) of case 55 and secured by cover 242 attached to back side
115 of case 55. The case 55 may also include depressible or touch
sensitive light operation button 242, depressible or touch
sensitive charging button 244 and charging/discharging port 254. In
some examples, the case may include charging indicator 246. In some
examples, the case 55 may include external memory slot 222. In some
examples, the case may include charging sensor 252.
[0201] The case 55 shown in FIG. 20B is the same as the case 55
shown in FIG. 20A, except that the case 55 in FIG. 20B includes
charging/discharging port 254 instead of separate dedicated
charging port 248 and discharging port 250. Charging/discharging
port 254 may provide for both charging power source 30 and the
internal power source of the handheld computing device 100 and
charging downstream ports via power source 30. Charging/discharging
port 254 may be any type of suitable port including those known in
the art such as a universal serial bus (USB) port and/or an
induction charger (for wireless charging). In some examples, case
55 may include an induction charger in addition to a USB-type
charging/discharging port.
[0202] Although the case 55 is shown in FIGS. 20A and 20B as
including external memory slot 222, these represent example
embodiments. In some examples, the case 55 may not include external
memory slot 222. Although the case 55 that is shown in FIGS. 20A
and 20B does not include light source(s) 210 and light cover(s)
220, these represent example embodiments. In some examples, the
case may also include light source(s) 210 and light cover(s) 220,
as shown, for example, in FIG. 16A-FIG. 17D.
[0203] As discussed above, the case 55 may be a one-piece structure
or may include a multi-piece design, for secure attachment of the
handheld computing device 100 to case 55. Referring next to FIG.
21A-FIG. 24F, example embodiments of case 55 configured as a
two-piece structure are described. In FIG. 21A-FIG. 24F, the case
55 is shown without the handheld computing device 100 coupled to
the case 55, for convenience in describing operation of the example
two-piece case designs.
[0204] The example two-piece structures of case 55 may be made from
the same materials described above. The sections of the two-piece
case may be formed from the same material or from different
materials, such as to ensure optimized protection and feel. Each
section of the two-piece case may be formed from the same material
or a combination of two or more different materials. It is
understood that FIG. 21A-FIG. 24F describe example two-piece case
designs, and that the disclosure is not limited to these examples.
It is also possible that the handheld computing device 100 may be
fastened to the case 55 with other means such as pre-positioned
screws, hook-and-loop fasteners, riveting, or any other kind of
mechanisms allowing a secure attachment. In some examples, the case
55 is removably attached to the handheld computing device 100,
allowing easy detaching for higher level of flexibility. In some
examples, the case 55 may be a permanent fixture of the handheld
computing device 100, for example, to provide a high level of
integration between the handheld computing device 100 and the
illumination device 1. Although two-piece case designs are
illustrated, it is understood that the case 55 may include any
suitable multi-piece design, including cases having three or more
structures.
[0205] Although the case 55 is shown in FIG. 21A-FIG. 24F does not
include light source(s) 210 and light cover(s) 220, these represent
example embodiments. In some examples, the case may also include
light source(s) 210 and light cover(s) 220, as shown, for example,
in FIG. 16A-FIG. 17D.
[0206] FIGS. 21A-21F illustrate an example two-piece case 55 having
pre-positioned protrusions 262 that fit into prepositioned recesses
266. In particular, FIG. 21A is a back view of case 55 with respect
to back side 115; FIG. 21B is a right side view of case 55 with
respect to side surface 90; FIG. 21C is an exploded back view of
case 55 with respect to back side 115; FIG. 21D is an exploded
right side view of case 55 with respect to side surface 90; FIG.
21E is a perspective view taken with respect to front side 110 of
case 55; and FIG. 21F is an exploded perspective view of case 55
taken with respect to front side 110.
[0207] The case 55 may include first section 260 and second section
264. The first section 260 may include one or more prepositioned
protrusions 262 on a bottom side. The second section 264 may
include one or more prepositioned recesses 266 on a top side
configured to be aligned with respective protrusion(s) 262. The
first section 260 may be attached to the second section 264 by
aligning and mechanically coupling protrusions 262 to recesses 266
(shown in FIGS. 21C and 21F). The first section 260 may be detached
from the second section 264 by decoupling protrusions 262 from
recesses 266. In operation, for example, the handheld computing
device 100 may be coupled to front side 110 of second section 264.
Next, first section 260 may be aligned and coupled to second
section 264, thereby securing the handheld computing device 100 to
case 55.
[0208] FIGS. 22A-22E illustrate an example two-piece case 55 having
pre-positioned protrusions 272 that fit into prepositioned recesses
276. In particular, FIG. 22A is a front view of case 55 with
respect to front side 110; FIG. 22B is a right side view of case 55
with respect to side surface 90; FIG. 22C is an exploded front view
of case 55 with respect to front surface 110; FIG. 22D is a
perspective view of case 55 taken with respect to front side 110;
and FIG. 22E is an exploded perspective view of case 55 with
respect to front side 110.
[0209] The case 55 may include first section 270 and second section
274. The first section 270 may include one or more prepositioned
protrusions 272 extending from a back side (corresponding to back
side 115). The second section 274 may include one or more
prepositioned recesses 276 on front side 110 configured to be
aligned with respective protrusion(s) 272, such that first section
270 overlaps with portion 275 of second section 274. The first
section 270 may also include aperture 135' configured to be aligned
with aperture 135 on the second section 274. The first section 270
may be attached to the second section 274 by aligning and
mechanically coupling protrusions 272 to recesses 276 (shown in
FIG. 22E). The first section 270 may be detached from the second
section 274 by decoupling protrusions 272 from recesses 276. In
operation, for example, first section 270 may be aligned and
coupled to second section 274. Next, the handheld computing device
100 may be coupled to front side 110 of case 55, thereby securing
the handheld computing device 100 to case 55.
[0210] FIGS. 23A-23F illustrate an example two-piece case 55 having
a pre-positioned tab 282 that slidably fits into prepositioned
notch 286. In particular, FIG. 23A is a front view of case 55 with
respect to front side 110; FIG. 23B is a right side view of case 55
with respect to side surface 90; FIG. 23C is a left side view of
case 55 with respect to side surface 90; FIG. 23D is an exploded
front view of case 55 with respect to front side 110; FIG. 23E is
an exploded right side view of case 55 with respect to side surface
90; and FIG. 23F is an exploded perspective view taken from front
side 110 of case 55.
[0211] The case 55 may include first section 280 and second section
284. The first section 280 may include prepositioned tab 282
extending from a bottom side. The second section 284 may include
prepositioned notch 286 in a top side configured to be aligned with
notch 282. As shown in FIGS. 23A-23C, notch 286 may extend from one
side surface 90 (e.g., the right-side surface) through a portion of
second section 284 towards the second side surface 90 (e.g., the
left side surface), without extending through the second side
surface (see FIG. 23C). The first section 280 may be attached to
the second section 284 by slidably fitting tab 282 into notch 286
(shown in FIGS. 23D and 23F). The first section 280 may be slidably
detached from the second section 284 by slidably removing tab 282
from notch 286. Because notch 286 does not fully extend from the
first side surface 90 to the second side surface 90, first section
280 may be fully positioned in notch 286 when edge 283 of tab 282
reaches notch edge 287. In operation, for example, first section
280 may be aligned and slidably fitted to second section 284. Next,
the handheld computing device 100 may be coupled to front side 110
of case 55, thereby securing the handheld computing device 100 to
case 55.
[0212] FIGS. 24A-24F illustrate an example two-piece case 55 having
a first section 290 pivotably coupled to a second section 294. In
particular, FIG. 24A is a front view of case 55 with respect to
front side 110, in a closed state; FIG. 24B is a left side view of
case 55 with respect to side surface 90, in a closed state; FIG.
24C is a front view of case 55 with respect to front side 110, in
an opened state; FIG. 24D is a perspective view of case 55 taken
from front side 110 with respect to the left side of case 55, in an
opened state; FIG. 24E is a perspective view of case 55 taken from
front side 110, in a closed state; and FIG. 24F is another
perspective view of case 55 taken from front side 110 with respect
to the right side of case 55, in an opened state.
[0213] The case 55 may include first section 290 and second section
294. The first section 290 may include one or more prepositioned
protrusions 292 extending toward second section 294. The first
section 290 may be pivotably coupled to the second section 294 by
pin 293. The second section 294 may include one or more
prepositioned recesses 296 arranged toward the first section 290
configured to be aligned with respective protrusion(s) 292. The
first section 290 may be attached to the second section 294 by
pivoting the first section 290 about pin 293 towards the second
section 294 and mechanically coupling protrusions 292 to recesses
296 (shown in FIGS. 24C-24F). The first section 290 may be
pivotably detached from the second section 294 by decoupling
protrusions 292 from recesses 296. In operation, for example, the
handheld computing device 100 may be coupled to front side 110 of
second section 264, with first section 290 pivotably detached from
recesses 296 of second section 294. Next, first section 290 may be
pivotably coupled to second section 294, thereby securing the
handheld computing device 100 to case 55.
[0214] Referring next to FIG. 25A-FIG. 29B, additional example
embodiments of illumination device 1 are described. It should be
noted that these embodiments may not necessarily be described to
the fullest extent because such descriptions are provided for in
the embodiments described above. In particular, the description for
any of the embodiments should be considered included in other
embodiments as long as there is not conflict between the
descriptions. Although the case 55 is shown in FIG. 25A-FIG. 29B
does not include light source(s) 10 and/or 210 and light cover(s)
20 and/or 220, these represent example embodiments. In some
examples, the case may also include light source(s) 10 and/or 210
and light cover(s) 20 and/or 220, as shown, for example, in FIG.
16A-FIG. 17D.
[0215] FIGS. 25A-27C illustrate example arrangements of case 55
having lens and/or cover attachment assembly 302 (also referred to
herein as attachment assembly 302) configured to overlay the camera
of computing device 100. In particular, FIG. 25A illustrates case
55 taken from back side 115 relative to attachment assembly 302;
FIG. 25B shows inset section 301 of FIG. 25A; FIGS. 26A-26B
illustrate an example attachment assembly 302; and FIGS. 27A-27C
illustrate another example attachment assembly 302.
[0216] As shown in FIGS. 25A and 25B, attachment assembly 302 may
be configured to be received in recess 300 of case 55 formed around
aperture 135. When attachment assembly 302 is coupled to recess
300, a lens and/or cover of attachment assembly 302 may overlay the
camera of computing device 100. In some examples, attachment
assembly 302 may be removably coupled to case 55. In some examples,

some examples, holder 304 of attachment assembly 302 may be
permanently coupled to case 55 and lens(s) 306 and/or a cover may
be removably coupled to holder 304.
[0217] In some examples, attachment assembly 302 may include a
cover to protect the camera from harm. In some examples, attachment
assembly 302 may include at least one optical lens (such as lens
306 shown in FIG. 26A). In some examples, attachment assembly 302
may include both a separate cover and lens(s) 306. Lens 306 may
include any lens suitable for modifying an image of an object
captured by the camera. Non-limiting examples of lens 306 may
include a wide-angle lens, a fisheye lens, a zoom lens, a telephoto
lens, etc. In some examples, the cover may be a transparent
material or may be tinted a particular color. In some examples,
case 55 may include one or more slots for holding attachment
assembly 302, a camera cover and/or one or more lenses 306.
[0218] As shown in FIGS. 26A and 26B, attachment assembly 302 may
include holder 304 having at least one groove 308. Groove(s) 308
may be configured to engage with one or more corresponding
projections on recess 300 (not shown) to secure holder 304 to case
55. Although FIGS. 26A and 26B illustrate holder 304 having
groove(s) 308, it is understood that holder 304 may include any
suitable attachment mechanism. As another example, holder 304 may
include one or more recesses (or protrusions) for engagement with
correspondingly positioned protrusions (or recesses) on recess 300
of case 55. Another example of holder 304 is described below with
respect to FIGS. 27A-27C.
[0219] Holder 304 may be configured for receiving a cover (not
shown) and/or at least one lens 306. Holder 304 may include outer
edge 310 and inner edge 312, with at least one of edges 310 and 312
configured to hold a cover and/or lens 306. FIGS. 26A and 26B
illustrate holder 304 coupled to lens 306 at outer edge 310. In
some examples, a cover may be coupled to outer edge 310. In some
examples, a cover may be coupled to inner edge 312. In some
examples, holder 304 may include a cover coupled to inner edge 312
and lens 306 coupled to outer edge 310. In some examples, holder
304 may include a first lens coupled to outer edge 310 and a second
lens (different or the same as the first lens) coupled to inner
edge 312. In some examples, holder 304 may be configured to hold
additional covers and/or lenses between edges 310 and 312.
[0220] In some examples, holder 304 may be configured with at least
one lens 306 (and/or cover) permanently attached to holder 304. In
some examples, the lens(s) 306 (and/or cover) may be removably
attached to holder.
[0221] FIGS. 27A-27C illustrate another example attachment assembly
302 with holder 304 having O-ring 314. In this example, O-ring 314
may be configured to engage a correspondingly positioned groove
(not shown) in recess 300 of case 55, such that when holder 304 is
attached to case 55, O-ring 314 is seated in the groove. It is
understood that FIGS. 26A-27C illustrate non-limiting examples of
attachment assembly 302 and that attachment assembly 302 may be
coupled to case 55 by any suitable means.
[0222] Referring next to FIGS. 28A-29B, case 55 have example sound
amplification mechanisms are shown. In particular, FIG. 28A is a
perspective view of case 55 with handheld computing device 100
coupled thereto taken from front side 110, with case 55 in a closed
state; FIG. 28B is a perspective view of case 55 taken from front
side 110, with case 55 in an opened state; FIG. 28C is a
perspective view of second section 322 of case 55; FIG. 29A is a
left side view of case 55 (with respect to side surface 90) in a
closed state; and FIG. 29A is a left side view of case 55 from side
surface 90 in an opened state.
[0223] Case 55 may include first section 320 and second section
322. Second section may be configured to cover the computing device
100 at bottom 95 of case 55. Second section 322 may be slidably
coupled to first section 320 (e.g., via sliding members in one of
sections 320 and 322 engaging with sliding slots in the other of
sections 320 and 322).
[0224] When case 55 is in an closed state (FIGS. 28A and 29A)
second section 322 may be in contact or in close proximity to one
or more sound output ports (not shown) of one or more loudspeaker
(not shown) of computing device 100, such that second section 322
may cover the sound output port(s) of computing device 100 and
reduce the sound output by the computing device 100. When case 55
is in an opened state (FIGS. 28B and 29B) second section 322 may be
spaced apart from computing device 100 by gap 324, such that second
section 322 may increase the sound output by the sound output
port(s). In addition, inside surface 328 (FIG. 28C) of second
section 322 may be configured to reflect sound away from case
toward front side 110, to further amplify and/or direct the sound
from computing device 100.
[0225] As shown in FIG. 28C, second section 322 may include one or
more apertures 326 positioned to correspond with the sound output
port(s) of the computing device 100. In this manner, apertures 326
may increase sound output from the sound output port(s) of
computing device 100 even when case 55 is in the closed positon (as
in FIGS. 28A and 28B).
[0226] In some examples, case 55 may include a single-pieced body
having one or more apertures 326 but without a slidable second
section 322. In some examples, case 55 may include slidable section
322 without including aperture(s) 326. In some examples, second
section 322 may be detachably coupled to first section 320. In some
examples, second section 322 may be slidably coupled to permanently
attached to first section 322. It is understood that FIGS. 28A-29B
illustrate non-limiting example mechanisms for sound amplification
and that case 55 may include other suitable sound amplification
mechanism.
[0227] In some embodiments, the illumination device may implement
shock absorbing features designed to protect the computing device
from falls, shaking, and the like. In some embodiments, the
illumination device may implement weather protective and/or dust
protective features. In some examples, the illumination device may
be designed to be water resistant. In some examples, the
illumination device may be sealed, such as with one or more gaskets
and/or plugs to cover any apertures (such as a charging port), to
protect the illumination device and/or computing device from
weather and/or dust. In other embodiments, a covering such as a
glass or acrylic may overlay the computing device's display to
prevent similar harm to the display of the computing device. In
some embodiments, the illumination device may include a covering
such as glass or acrylic to overlay the computing device's camera,
to protect the camera of the computing device (e.g., from dust,
dirt, fingerprints, etc.). In some examples, the covering for the
camera may be attached to the illumination device in a permanent or
removable manner. In yet other embodiments, the light sources may
flash, strobe, or otherwise be used to signify that an emergency is
occurring or to otherwise garner attention from another. In other
embodiments, a "selfie stick" or other apparatus may be coupled to
the illumination device to provide flexibility in use. In some
examples, one or more attachment assembly may include one or more
permanently or removably attachable protrusions for supporting the
handheld computing device in a hands-free mode, for coupling the
handheld computing device to another object and/or for easier
grasping of the handled computing device. In some embodiments, the
illumination device may have slots for cash, credit cards, debit
cards, and the like. Even still, in other embodiments there may be
an integrated battery and/or signal booster which can provide
extended battery life and enhanced signal quality when
necessary.
[0228] As indicated above, it is in the purview of the current
disclosure that a series of computer applications or programs may
accompany the illumination device disclosed herein. These
applications may facilitate the use of the illumination device and
ensure that it is safe, well-controlled, and optimized to assist
the use of some other applications.
[0229] For example, when the illumination device is sufficiently
connected and synergized with the computing device, a program may
be used to specifically control the light source of the
illumination device to adjust the luminous intensity, viewing
angle, color, and lighting pattern of the light source. A user of a
handheld computing device may turn on the illumination device
simply to provide general illumination. A handheld computing
device, in such situations, may be used as a flashlight in a dark
place. When the illumination device is equipped with an ambient
light sensor, as indicated above, it is possible to have a program
that automatically adjusts the luminous intensity of the light
source based on ambient light conditions.
[0230] Another example is a video call program that specifically
integrates the usage of the illumination device. Before the user
transmits his/her image, he/she may view the image on the display
screen to obtain optimal results. The program may control both the
camera and the illumination device, allowing easy adjustment
without switch to another program that controls the camera. The
program may facilitate this process by setting certain criteria
that help the user to optimize the image. For instance, the program
may display on the screen a dotted-line contour of a generic human
face, while the user of the handheld computing device may adjust
the distance of his/her face to the device and/or the zoom and
focus of the front camera to make the image of his/her face to fit
the dotted-line contour, achieving optimal results. A slight
variation of this design is to display a generic eye contour that
allows the user to make adjustment to match his/her image to the
contour. Or the program may directly show suggestions or
recommendations on the display screen to urge the user to turn the
illumination device on, make it brighter or dim it, or to adjust
the zoom and/or focus of the camera for optimal image. In essence,
the illumination intensity may be adjusted according to the optimal
focal length of the camera. Such a basic design should also be
applicable to other programs. Similarly, a photo or video capturing
program having the same features may be installed to assist the use
of the illumination device. The photo or video capturing program
may aid the user in adjusting the illumination device to obtain the
best result as to picture quality. In some examples, the photo or
video capturing program may integrate voice command recognition via
the computing device with control of the lights of the illumination
for capturing photos and videos. The program may allow the user to
capture a photo or a video with the camera of the computing device
through one or more voice commands together with illumination by
the illumination device. Another example is a "makeup mirror"
application that integrates the illumination device with the front
camera. In some cases, a user of a handheld computing device would
like to see his/her own image to be captured by the front camera
and be displayed on the display screen simultaneously. The user
then would be able to assess his/her appearance and make necessary
adjustments. To achieve optimal results, the "makeup mirror"
application would allow the user to control the luminous intensity,
viewing angle, color, and lighting pattern of the light source in
the illumination device, or such features may be adjusted
automatically by the application when the ambient light sensor is
included and used. Combined with the frame stand or hanger
structure that may be a part of the attachment assembly, the user
may set the handheld computing device in an upright position
without actually holding the device, freeing up both of the user's
hands for optimal maneuvering, while the whole process is being
conducted under ideal illumination.
[0231] Also indicated as above, the illumination device may serve
as indicator or signaling source for the status of the handheld
computing device. For example, when there is an incoming call to a
small phone, a handheld computing device, the light source of the
illumination device may light up or change the luminous intensity,
viewing angle, color, and/or lighting pattern of the lights. The
lights may flash, or subsections of the lights are turned on
rotationally. A more complex set up may allow the user of the smart
phone to establish and manage specific profiles--specific
combination of luminous intensity, viewing angle, color, and/or
lighting pattern--for the illumination device. The user may choose
different profiles to match different callers. Such an application
controls the illumination device in somewhat similar ways as ring
tones are managed for smart phones, further enriching the user
experience.
[0232] Furthermore, since the illumination device may be used as
signals for the computing device to which the illumination device
is connected, it is possible that the illumination device may be
integrated with other program or application being used by the
computing device. For example, it is possible to set up the
illumination device that when a certain game is being played, the
illumination device is turned on and the luminous intensity,
viewing angle, color, and/or lighting pattern of the lights change
with the progress of the game. A similar implementation is also
possible for music. Certain light profiles may be integrated with
the music program on the computing device, allowing the lights to
flash rhythmically, for example, when the music is being
played.
[0233] Although this disclosure has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made only by way of illustration and that
numerous changes in the details of construction and arrangement of
parts may be resorted to without departing from the spirit and the
scope of the disclosure.
