DETAILED DESCRIPTION
[0020] The following description is merely exemplary in nature and
is not intended to limit the present disclosure, application, or
uses.
[0021] A lighted item according to one aspect of the invention
generally includes a light-conducting or light-transmission
portion. The lighted item also includes at least one light source
positioned to emit light into the light-conducting portion, which,
in turn conducts or transmits light to at least one predetermined
portion (e.g., a portion having or integrally defining one or more
indicia, a portion having or integrally defining a graphic element,
etc.) for highlighting the predetermined portion. Light may also be
conducted or transmitted through the light-conducting portion to a
light-transmissive portion for highlighting an element (e.g.,
edible, confection, drink, consumable, an object not intended for
human consumption, etc.) that is engaged to the light-conducting
portion.
[0022] In various embodiments of the invention, a lighted item can
take on various shapes and forms. Exemplary embodiments of the
invention include a lighted iced or frozen confection 100 (FIG. 1),
a lighted lollypop 200 (FIG. 2), a lighted snow cone cup 300 (FIG.
3), a lighted cotton candy holder 400 (FIG. 4), a lighted candy
ring pop 500 (FIG. 5), a lighted pacifier 600 (FIG. 6), a lighted
receptacle 700 (FIGS. 7A and 7B), a lighted label 800 (FIGS. 8A and
8B), a lighted key holder 900 (FIGS. 9 and 10), a lighted coaster
and placemat combination 1100 (FIG. 11), and lighted tableware,
such as a lighted fork 1200A (FIG. 12A), a lighted spoon 1200B
(FIG. 12B), a lighted knife 1200C (FIG. 12C), lighted chopsticks,
lighted plates, lighted dishes, lighted glassware, among other
tableware and eating utensils, etc.
[0023] In various embodiments of the invention, a lighted item
includes one or more indicia that are highlighted (e.g.,
illuminated, backlit, etc.) by light from a light source. This
indicia can include a wide range of graphic images, graphic
elements, designs, artwork, distinctive marks, identifying symbols,
company logos, company contact information, text, alphanumeric
characters, advertisements, trademarks, trade names, service marks,
sports teams insignias, names, monograms, photographs, among
others. In yet other embodiments, the lighted item may not include
any such indicia, but instead include a predetermined portion
without any indicia that is highlighted by light from a light
source.
[0024] FIG. 1 illustrates an exemplary lighted iced or frozen
confection 100, such as a popsicle or ice cream bar. As shown in
FIG. 1, the lighted frozen confection 100 includes a popsicle stick
104 and an edible 108 coupled to the popsicle stick 104. The edible
108 can include a variety of frozen confections, including
popsicles, fudgsicles, ice cream, flavored ice, among others. The
lighted frozen confection 100 also includes at least one light
source 112 coupled to the popsicle stick 104.
[0025] At least a portion 116 of the popsicle stick 104 is
light-transmissive. The light-transmissive portion 116 defines one
or more indicia 120 which are highlighted by light 124 from the
light source 112. In an exemplary embodiment, the
light-transmissive portion 116 includes a translucent plastic
material into which is etched "INDICIA" 120. Alternatively, the
popsicle stick 104 can include one or more indicia which are
light-blocking such that the indicia contrast with the surrounding
portions of the popsicle stick 104 through which light 124
passes.
[0026] In some embodiments, the light-transmissive portion 116 of
the popsicle stick 104 has a higher light transmissibility (allows
more light to pass therethrough) than the adjacent portions of the
popsicle stick 104. The light-transmissive portion 116 allows light
124 from the light source 112 to pass therethrough, thus becoming
externally visible.
[0027] In an exemplary embodiment, the indicia 120 are etched or
carved (e.g., with a cutting tool, knife, razor blade, laser,
chemically etched, drilled, etc.) into the material forming the
popsicle stick 104. This etching can increase the light
transmissibility of the etched indicia and/or allow the indicia to
alter (e.g., capture, refract, disperse, diffuse, diffract, etc.)
light traveling within the popsicle stick 104. Etching the indicia
120 can affect the way that the light 124 interacts with the etched
indicia 120. For example, with relative deeply carved or etched
indicia, the light 124 can be captured in the edges of and thus
highlight the indicia 120.
[0028] Preferred angle(s) and/or thickness dimensions (e.g., height
or depth, etc.) at which the indicia are formed in the popsicle
stick material may depend on the particular application. In
exemplary embodiments, the indicia can be formed (e.g., etched,
carved, etc.) into the popsicle stick material at an acute angle of
about +/-45 degrees relative to the direction of travel of the
light 124.
[0029] The indicia can be etched into an outer or external surface
of the popsicle stick material. Additionally, or alternatively, the
indicia can be etched into an internal surface of the popsicle
stick material. For example, in one exemplary embodiment, the
popsicle stick may comprise a two-piece construction. In which
case, indicia can be etched into a surface of either or both
pieces. Next, the pieces can be arranged such that the surface into
which the indicia were etched faces the opposing piece and such
that the light source, power source, and conductors are positioned
between the pieces. The pieces can then be joined to form the
lighted popsicle stick. These exemplary manners by which the
indicia can be provided (e.g., etched internally or externally into
the popsicle stick) can also be applied to other embodiments of the
invention such as those shown in FIGS. 2 through 12.
[0030] Alternatively, indicia may be provided in any of the various
embodiments disclosed herein using other suitable methods, such as
silk-screening, pad printing, optical fibers, adhesive stickers,
molding (e.g., indicia formed during an injection molding process,
etc.), among other suitable methods.
[0031] Alternatively, or additionally, the light-transmissive
portion 116 may be defined by one or more openings or holes through
the popsicle stick 104. The holes can be arranged to form the
indicia 120. Accordingly, light 124 from the light source 112 can
pass through the holes and becomes visible external to the popsicle
stick 104. The visible light passing through the holes will thus
appear in the form of the indicia 120.
[0032] Portions of the popsicle stick 104 adjacent the
light-transmissive portion 116 may have means for inhibiting light
from inadvertently escaping out of those portions of the popsicle
stick 104. For example, portions of the popsicle stick 104 may be
substantially opaque, reflective, faceted, etc. in order to help
direct light through the popsicle stick 104 and/or towards the
indicia 120. Additionally, or alternatively, the popsicle stick 104
can be configured (e.g., shaped, sized, and formed of suitable
materials, etc.) so that the popsicle stick 104 functions to guide
or conduct at least some of the light 124 through the interior of
the popsicle stick 104, for example, by successive internal
reflections. Accordingly, the selection of material(s) for the
popsicle stick 104 can depend at least in part on the material's
ability to channel or transmit light 124 from the light source 112
through the popsicle stick 104 and/or the material's ability to at
least reduce the amount of light that inadvertently escapes out of
the popsicle stick 104. In these exemplary manners (which can also
be applied to other embodiments of the invention including the
embodiments shown in FIGS. 2 through 12), at least some light 124
from the light source 112 can remain within the popsicle stick 104
at least until the light 124 reaches the indicia 120. This, in
turn, can increase the amount of available light for highlighting
the indicia 120 and/or edible 108.
[0033] A wide range of materials, preferably light-weight and
chemically non-reactive to the edible 108, can be used for the
popsicle stick 104 and its light-transmissive portion 116. Further,
the same materials do not have to be used for the
light-transmissive portion 116 and the other popsicle stick
portions. Exemplary materials that can be used for the lighted
popsicle stick include transparent materials, translucent
materials, other light-altering materials (e.g., materials that
alter light by refraction, diffraction, diffusion, and/or
dispersion), flexible materials, plastic materials, vinyl
materials, polystyrene, polyvinylchloride (PVC) (e.g.,
environmentally PVC, medical grade PVC, etc.) and materials capable
of being mass produced with relatively low manufacturing costs,
among other materials suitable for the intended purpose. The type
of material used for the light-transmissive portion 116 may depend
at least in part on the particular type and intensity of light
produced by the light source. In addition, various manufacturing
processes can be used for forming the popsicle stick, including
injection molding and casting (e.g., casting poly resin, casting
acrylic, etc.).
[0034] Optionally, the edible 108, or at least a portion thereof,
can also be light-transmissive. In the illustrated embodiment of
FIG. 1, the light source 112 directs light 124 generally upwardly
through the popsicle stick 104. At least a portion 124' of the
light 124 travels through the popsicle stick 104 out its end 128
and into the edible 108. In this exemplary manner, light 124' from
the light source 112 can illuminate the edible 108, or at least a
portion thereof.
[0035] Popsicles and other ice confections can be colored
consistent with their flavoring. For example, a lime-flavored ice
confection can be green in color, a banana-flavored ice confection
can be yellow, a grape-flavored ice confection can be purple, and
so on. Therefore, when light radiates through the popsicle stick
104 and into the edible 108, the light also radiates through the
edible 108 to create a colorful glow.
[0036] In other embodiments, however, the edible can be generally
clear or transparent. To produce a colorful glow consistent with
the edible's flavor, the light source may produce light having a
particular color and/or produce broadband light that travels
through a colored filter within the popsicle stick. In yet other
embodiments, the edible, or at least a portion thereof, can be
ultraviolet-reactive (e.g., include an ultraviolet-reactive food
additive, etc.), and the light source can produce ultraviolet light
for illuminating the ultraviolet-reactive edible. For example, the
edible, or at least a portion thereof, can be responsive to the
ultraviolet A (UVA) radiation component of black light produced by
the light source, which, in turn, produces a visually stimulating
effect.
[0037] While not shown in FIG. 1, the edible 108 can also define
one or more indicia, which are the same as or different than the
indicia 120 defined by the popsicle stick 104. For example, the
lollypop stick 204 and candy piece 208 in FIG. 2 both define
indicia 220 and 220', respectively, which are highlighted by light
224, 224' from the light source 212.
[0038] With further reference to FIG. 1, the light source 112
includes a single LED coupled to the popsicle stick 104.
Alternatively, other quantities of LEDs and/or other suitable light
sources can be employed such as incandescent, laser, fluorescent,
phosphorescent, chemiluminescent, halogen, fiber optics,
electroluminescent, neon light sources, ultraviolet lights, black
lights, and the like.
[0039] In the illustrated embodiment, the light source 112 is
disposed entirely within the popsicle stick 104 adjacent an end
portion 132 of the popsicle stick 104. Alternatively, the light
source 112 need not be positioned entirely within the popsicle
stick 104. Instead, the light source 112 may be partially or
entirely disposed external to the popsicle stick 104. The light
source 112 can also be disposed at other locations within the
popsicle stick 104 besides the end portion 132.
[0040] The lighted item 100 also includes a power source
compartment or receptacle 136 defined within the end portion 132 of
the popsicle stick 104. The power source receptacle 136 is adapted
to receive at least one power source 140 therein and to
electrically connect the power source 140 to the light source 112
via conductive leads 144. Alternatively, the power source 140 need
not be positioned entirely within the popsicle stick 104. Instead,
the power source 140 may be partially or entirely disposed external
to the popsicle stick 104. The power source compartment 136 can
reside elsewhere, such as at other locations within the popsicle
stick 104.
[0041] In FIG. 1, the power source 140 is a single watch battery,
although other suitable types and numbers of power sources can be
used depending on the particular application. The power source 140
can include any suitable means of providing energy to the light
source 112 such as renewable batteries, rechargeable batteries,
disposable batteries, power cells, solar cells, watch batteries,
and other suitable power sources, including kinetic power sources.
If rechargeable, such power source 140 could be rechargeable by
solar, magnetic, electrical, and chemical means, and the like or
any combination thereof.
[0042] To allow a user internal access to the power source
compartment 136, for example, to install, replace, or remove
batteries, the power source container 136 may include a removable
portion. The removable portion may be engaged with the power source
compartment 136 using a suitable fastening system or method (e.g.,
a threaded connection, an interference fit, resilient ribs, among
others).
[0043] In the illustrated embodiment, the lighted popsicle stick
104 includes a push-button switch 148 for switchably connecting the
light source 112 to the power source 140, although other switching
means can also be employed. The switch 148 is positioned within the
popsicle stick 104 and is coupled to an externally flexible surface
portion 152 of the stick 104 such that application of external
pressure upon the externally flexible surface portion 152 activates
the switch 148 thereby causing operation of the light source 112.
The external pressure may, for example, be applied by the user
squeezing the stick 104 at the externally flexible surface portion
152. The switch 148 may also allow the user to cycle through the
various display modes or select a particular color of light to be
emitted by the light source 112 by successively squeezing the stick
104 at about the externally flexible surface portion 152.
Additionally, the switch 148 may also allow the user to dim or
brighten the intensity of the light, for example, by holding down
the switch 148 with continuously applied pressure to the popsicle
stick 104 at about the externally flexible surface portion 152.
This exemplary means for switchably connecting the light source 112
to the power source 140 can also be applied to other embodiments of
the invention such as those shown in FIGS. 2 through 12.
[0044] In another embodiment, the switching means can include
electrical terminals located externally on the popsicle stick 104
(e.g., at about portion 152, etc.) such that the user's hand, upon
grasping the stick 104, electrically connects the terminals to one
another, thus completing a circuit for power delivery from the
power source 140 to the light source 112.
[0045] In various embodiments, the light source 112, power source
140, switch 148, and/or conductors 144 can be encapsulated by the
material forming the popsicle stick 104 in a fluid-tight fashion.
This, in turn, can help prevent liquid (e.g., the iced-confection
after it begins to melt, a user's perspiration, rain, etc.) from
contacting (and potentially causing problems with the operation of)
the various components encapsulated within the popsicle stick 104.
In addition, this encapsulation can also at least help support and
retain the positioning of the light source 112, power source 140,
switch 148, and/or conductors 144. Further, this exemplary means
for encapsulating the light source 112, power source 140, switch
148, and/or conductors 144 can also be applied to other embodiments
of the invention such as the embodiments shown in FIGS. 2 through
12. In one exemplary embodiment, this encapsulation can be
accomplished by applying a substantially liquid resin (e.g., a food
grade liquid resin) over the light source 112, power source 140,
switch 148, and/or conductors 144, and then allowing the resin to
solidify.
[0046] In various embodiments, the inside of the popsicle stick 104
can be generally hollow such that a cavity is defined therein.
Alternatively, the popsicle stick 104 can be substantially
solid.
[0047] FIG. 2 illustrates a lighted lollypop 200 embodying several
aspects of the invention. As shown in FIG. 2, the lighted lollypop
200 includes a lollypop stick 204 and a confection, such as a piece
of candy 208. The candy piece 208 is coupled to the lollypop stick
204. At least one light source 212 is also coupled to the lollypop
stick 204. The lighted lollypop stick 204 can be disposable or
reusable, as can other embodiments of the invention including the
embodiments shown in FIGS. 1 and 3-12.
[0048] The lollypop stick 204 and the candy piece 208 can both
include light-transmissive portions 216 and 216' which respectively
define indicia 220 and 220'. In the illustrated embodiment, the
lollypop stick's light-transmissive portion 216 defines indicia 220
as "RAMS", which can be highlighted by light 224 from the light
source 212. The candy piece 208 defines indicia 220' resembling a
football helmet. Alternatively, other suitable indicia can be
defined (e.g., etched into, etc.) by the light-transmissive
portions 216 and 216'.
[0049] When connected to the power source 240, the light source 212
directs light 224 generally through the lollypop stick 204. At
least a portion 224' of the light 224 travels through the lollypop
stick 204 out its end portion 228 and into the candy piece 208. In
this exemplary manner, light 124' from the light source 112 can
illuminate the candy piece 208 and the indicia 220' defined
thereby.
[0050] Portions of the lollypop stick 204 adjacent the
light-transmissive portion 216 may have means for inhibiting light
from inadvertently escaping out of those portions of the lollypop
stick 204. For example, portions of the lollypop stick 204 may be
substantially opaque, reflective, faceted, etc. in order to help
direct light through the lollypop stick 204 and/or towards the
indicia 220. Additionally, or alternatively, the lollypop stick 204
can be configured (e.g., shaped, sized, and formed of suitable
materials, etc.) so that the lollypop stick 204 functions to guide
or conduct at least some of the light 224 through the interior of
the stick 204, for example, by successive internal reflections.
Accordingly, the selection of material(s) for the lollypop stick
204 can depend at least in part on the material's ability to
channel or transmit light 224 from the light source 212 through the
stick 204 and/or the material's ability to at least reduce the
amount of light that inadvertently escapes out of the lollypop
stick 204. In this exemplary manner, at least some light 224 from
the light source 212 can remain within the lollypop stick 204 at
least until the light 224 reaches the indicia 220. This, in turn,
can increase the amount of available light for highlighting the
indicia 220 and/or the candy piece 208, thereby enhancing the
illumination or highlighting effect.
[0051] A wide range of materials, preferably light-weight and
chemically non-reactive to the candy piece 208, can be used for the
lollypop stick 204 and its light-transmissive portion 216. Further,
the same materials do not have to be used for the
light-transmissive portion 216 and the other lollypop stick
portions. Exemplary materials that can be used for the lollypop
stick 204 include transparent materials, translucent materials,
other light-altering materials (e.g., materials that alter light by
refraction, diffraction, diffusion, and/or dispersion), flexible
materials, plastic materials, vinyl materials, polystyrene,
polyvinylchloride (PVC) (e.g., environmentally PVC, medical grade
PVC, etc.) and materials capable of being mass produced with
relatively low manufacturing costs, among other materials suitable
for the intended purpose. The type of material used for the
lollypop stick 204 may depend at least in part on the particular
type and intensity of light produced by the light source. In
addition, various manufacturing processes can be used for forming
the lollypop stick, including injection molding and casting (e.g.,
casting poly resin or acrylic, etc.).
[0052] Because the candy piece 208 can also be colored consistent
with its flavoring (e.g., an orange-flavored candy piece can be
orange in color, etc.), the light 224' radiating through the edible
208 can create a colorful glow. The candy piece 208, however, can
also be transparent and/or be ultraviolet-reactive (e.g.,
responsive to the UVA radiation component of black light). To
provide and/or enhance a colorful glow consistent with the candy
piece's flavor, the light source may produce light having a
particular color and/or produce broadband light that travels
through a colored filter within the lollypop stick. This exemplary
means for producing thematic light can be applied to other
embodiments of the invention including the embodiments shown in
FIGS. 1 through 12.
[0053] In the illustrated embodiment, the light source 212 is
disposed entirely within the lollypop stick 204 adjacent an end
portion 232 of the lollypop stick 204. Alternatively, the light
source 212 need not be positioned entirely within the lollypop
stick 204. Instead, the light source 212 may be partially or
entirely positioned external to the lollypop stick 204. The light
source 212 can also be positioned at other locations within the
lollypop stick 204 besides the end portion 232.
[0054] The lighted item 200 can also include a power source
compartment or receptacle 236 within the end portion 232 of the
lollypop stick 204. The power source receptacle 236 is adapted to
receive at least one power source 240 therein and to electrically
connect the power source 240 to the light source 212 via conductive
leads 244. Alternatively, the power source compartment 236 can
reside elsewhere, such as at other locations external to or within
the lollypop stick 204.
[0055] In the illustrated embodiment, the lighted lollypop 200
includes a push-button switch 248 for switchably connecting the
light source 212 to the power source 240, although other switching
means can also be employed. The switch 248 is positioned within the
lollypop stick 204 and is coupled to an externally flexible surface
portion 252 of the lollypop stick 204 such that application of
external pressure upon the externally flexible surface portion 252
activates the switch 248 thereby causing operation of the light
source 212. The external pressure may, for example, be applied by
the user squeezing the lollypop stick 204 at the externally
flexible surface portion 252. The switch 248 may also allow the
user to cycle through the various display modes or select a
particular color of light to be emitted by the light source 212 by
successively squeezing the lollypop stick 204 at about the
externally flexible surface portion 252. Additionally, the switch
248 may also allow the user to dim or brighten the intensity of the
light, for example, by holding down the switch 248 with
continuously applied pressure to the lollypop stick 204 at about
the externally flexible surface portion 252.
[0056] FIG. 3 illustrates a lighted cup 300 which embodies several
aspects of the invention. As shown in FIG. 3, the lighted cup 300
is generally cone-shaped and can be used as a snow cone cup. As
with other embodiments of the invention, the lighted cup 300 can be
disposable or reusable. Alternatively, the lighted cup 300 can
include other suitable shapes, such as a coffee mug, beverage cup
or glass, wine glass, etc.
[0057] The lighted cup 300 includes a light-transmissive portion
316 defining one or more indicia 320. In the exemplary embodiment,
the indicia 320 resemble a mouse's head, although other indicia can
also be employed.
[0058] The lighted cup 300 also includes at least one light source
312, such as one or more LEDs or other suitable light source. The
light source 312 is switchably connectable to at least one power
source 340 (e.g., a watch battery, etc.) received within a power
source compartment 336 defined by the lighted cup 300. In the
illustrated embodiment of FIG. 3, conductive leads 344 connect the
LEDs 312 with the 340 within the power source compartment 336
defined by the lighted cup 300.
[0059] When connected to the power source 340, the light source 312
emits light 324 which highlights the indicia 320. Light 324 from
the light source 312 can be guided or conducted by the cup's
sidewalls 360 such that the light travels generally between the
inner and outer surfaces 364 and 368 of the cup's sidewalls 360 and
into the flavored ice or snow portion 308. In this exemplary
manner, the flavored ice, or at least a portion thereof, can be
illuminated by light 324' from the light source 312.
[0060] Portions of the cup's sidewalls 360 adjacent the
light-transmissive portion 316 have means for inhibiting light from
inadvertently escaping out of those portions of the cup's sidewalls
360. For example, portions of the cup's sidewalls 360 may be
substantially opaque, reflective, faceted, etc. in order to help
guide light 324 generally upwardly between the inner and outer
surfaces 364 and 368 of the cup's sidewalls 360 and/or towards the
indicia 320. Additionally, or alternatively, the cup's sidewalls
360 can be configured (e.g., shaped, sized, and formed of suitable
materials, etc.) so that the cup's sidewalls 360 function and/or
operate to guide or conduct at least some of the light 324
generally between the inner and outer surfaces 364 and 368 of the
cup's sidewalls 360, for example, by successive internal
reflections. Accordingly, the selection of material(s) for the
cup's sidewalls 360 can depend at least in part on the material's
ability to channel or transmit light 324 from the light source 312
generally between the inner and outer surfaces 364 and 368 of the
cup's sidewalls 360 and/or its ability to at least reduce the
amount of light that inadvertently escapes inwardly or externally
from within the cup's sidewalls 360. This, in turn, can increase
the amount of available light for highlighting the indicia 320
and/or flavored snow 308, thereby enhancing the illumination or
highlighting effect.
[0061] A wide range of materials, preferably light-weight and
chemically non-reactive to the edible 308, can be used for the
cup's sidewalls 360 and its light-transmissive portion 316.
Further, the same materials do not have to be used for the
light-transmissive portion 316 and the other popsicle stick
portions. Exemplary materials that can be used for the cup 300
include transparent materials, translucent materials, other
light-altering materials (e.g., materials that alter light by
refraction, diffraction, diffusion, and/or dispersion), flexible
materials, plastic materials, vinyl materials, polystyrene,
polyvinylchloride (PVC) (e.g., environmentally PVC, medical grade
PVC, etc.) and materials capable of being mass produced with
relatively low manufacturing costs, among other materials suitable
for the intended purpose. The type of material used for the cup 300
and light-transmissive portion 316 may depend at least in part on
the particular type and intensity of light produced by the light
source. In addition, various manufacturing processes can be used
for forming the cup 300, including injection molding and casting
(e.g., casting poly resin or acrylic, etc.).
[0062] The snow cone cup 300 can also include an externally
flexible surface portion 352, and at least one switching device 348
(e.g., a push button switch, among other suitable switching means,
etc.) coupled to the externally flexible surface portion 352 such
that application of external pressure upon the externally flexible
surface portion 352 activates the switching device 348. Activation
of the switching device 348 connects the light source 312 to the
power source 340.
[0063] In other embodiments, the snow cone cup 300 can include
electrical terminals for switchably connecting the light source 312
to the power source 340. For example, the electrical terminals can
be located within the snow cone cup 300 such that flavored ice or
liquid (after ice has melted) within the snow cone cup 300 causes
electrical contact between the terminals to complete the circuit
for power delivery to the light source 312 from the power source
340. In a preferred implementation, the terminals are located
within the snow cone cup 300 at a bottom portion thereof. In this
exemplary manner, the electrical terminals can be electrically
connected to one another by the flavored ice or liquid until all
(or at least substantially all) of the flavored ice or liquid has
been removed (e.g., consumed by the user or dumped out) from the
snow cone cup 300. Or for example, the electrical terminals can be
located externally on the snow cone cup 300 such that the user's
hand, upon grasping the snow cone cup 300, electrically connects
the terminals to one another, thus completing the circuit for power
delivery to the light source 312 from the power source 340. The
exemplary means for switchably connecting the light source 312 to
the power source 340 described above can also be applied to other
embodiments of the invention such as those shown in FIGS. 1 through
12.
[0064] FIG. 4 illustrates a lighted cotton candy holder 400 which
embodies several aspects of the invention. As shown in FIG. 4, the
lighted cotton candy holder 400 comprises a generally cone-shaped
member 404, which may be used to receive and retain cotton candy
408. As with other embodiments of the invention, the lighted cotton
candy holder can be disposable or reusable. Alternatively, other
suitable shapes can be employed for the lighted cotton candy
holder.
[0065] The lighted cotton candy holder 400 includes a
light-transmissive portion 416 defining one or more indicia 420
(e.g., "WALT DISNEY WORLD".RTM. theme park, etc.). For example,
indicia 420 can be etched or carved into the holder 400.
[0066] The lighted cotton candy holder 400 also includes at least
one light source 412, such as one or more LEDs and/or other
suitable light sources. The light source 412 is switchably
connectable with at least one power source 440 (e.g., a watch
battery, etc.) within a power source compartment 436 defined by the
lighted cotton candy holder 400.
[0067] When connected to the power source 440, the light source 412
emits light 424 which highlights the indicia 420. Light 424' from
the light source 412 also passes through the cotton candy holder
400, out an end 428 thereof, and into the cotton candy 408. Because
the cotton candy 408 is porous, light 424' radiating from within
the cotton candy 408 causes the cotton candy 408 to emanate a
colorful glow. In this exemplary manner, the cotton candy 408, or
at least a portion thereof, can be illuminated with light 424' from
the light source 412.
[0068] The cotton candy holder 400 may have means for inhibiting
light from inadvertently escaping out of the cotton candy holder
400. For example, the cotton candy holder 400 may be configured
(e.g., shaped, sized, have opaque portions, formed of suitable
materials, etc.) so as to at least help direct light through the
holder 400 and/or towards the indicia 420 and/or to at least reduce
the amount of light escaping from the holder 400. In this exemplary
manner, the amount of light available for highlighting the indicia
420 and/or the cotton candy 408 can be increased, thereby enhancing
the illumination or highlighting effect.
[0069] The indicia 420 may be formed with a sufficient thickness
relative to (e.g., at a sufficient height or depth into, etc.) the
holder 400 and/or at an acute angle relative to the direction of
travel of the light 424 so as to increase the light
transmissibility of the indicia 420 and/or allow the indicia 420 to
alter (e.g., capture, refract, disperse, diffuse, diffract, etc.)
light traveling within the holder 400. Etching the indicia 420 can
affect the way that the light 424 interacts with the etched indicia
420. For example, with relative deeply carved or etched indicia,
the light 424 can be captured in the edges of the indicia 420,
which, in turn, highlights the indicia 420 relative to its
surrounding environment.
[0070] In some embodiments, the cotton candy holder can also
include an externally flexible surface portion and at least one
switching device coupled to the externally flexible surface portion
such that application of external pressure upon the externally
flexible surface portion activates the switching device. This, in
turn, electrically connects the light source 412 to the power
source 440. Alternatively, other switching means can be employed
for the cotton candy holder.
[0071] FIG. 5 illustrates a lighted candy ring pop 500 that
embodies several aspects of the invention. As shown in FIG. 5, the
lighted candy ring pop 500 includes a base portion 504 and a ring
or annular portion 506 for placing the candy ring pop 500 on a
user's finger. The lighted candy ring pop 500 also includes a piece
of candy 508 coupled to the base portion 504.
[0072] At least one of the base portion 504 and the candy piece 508
define one or more indicia. In the illustrated embodiment, the
candy piece 508 is light-transmissive and defines one or more
indicia 520 (e.g., "SEAN", etc.)
[0073] The lighted candy ring pop 500 also includes at least one
light source 512, such as one or more LEDs and/or other suitable
light sources. The light source 512 is switchably connectable with
at least one power source 540 (e.g., a watch battery, etc.) within
a power source compartment 536 defined by the lighted candy ring
pop 500.
[0074] When connected to the power source 540, the light source 512
emits light 524 which highlights the indicia 520. Light 524 from
the light source 512 also passes through and illuminates the candy
piece 508, or at least a portion thereof. Because the candy piece
508 can be colored consistent with its flavoring (e.g., a
cherry-flavored candy piece can be red, etc.), light 524 radiating
through the edible 508 can create a colorful glow. Additionally, or
alternatively, the light source may produce light having a
particular color and/or produce broadband light that travels
through a colored filter to create or further enhance the colorful
glow.
[0075] The base portion 504 can be disposable or reusable. The
indicia 520 may be formed with a sufficient thickness (e.g., with a
sufficient height or depth, etc.) and/or acute angle relative to
direction of travel of the light 524 so as to increase the light
transmissibility of the indicia 520 and/or allow the indicia to
alter (e.g., capture, refract, disperse, diffuse, diffract, etc.)
light 524. This, in turn, can enhance the illuminating or
highlighting effect imparted to the indicia 520 by light 524.
[0076] FIG. 6 illustrates a lighted pacifier 600 that embodies
several aspects of the invention. As shown in FIG. 6, the lighted
pacifier 600 includes a base portion 604 and a portion 606 adapted
to be readily grasped or coupled to a baby's finger. The lighted
pacifier 600 also includes a nipple 608 coupled to the base portion
604.
[0077] At least one of the base portion 604 and the nipple 608
define one or more indicia. In the illustrated embodiment, the
nipple 608 is light-transmissive and defines one or more indicia
620.
[0078] The lighted pacifier 600 also includes at least one light
source 612, such as one or more LEDs or other suitable light
source. The light source 612 is switchably connectable with at
least one power source 640 within a power source compartment 636
defined by the lighted pacifier 600.
[0079] When connected to the power source 640, the light source 612
emits light 624 which highlights the indicia 620. Light from the
light source 612 also passes through and illuminates the nipple
608, or at least a portion thereof.
[0080] The indicia 620 may be formed with a sufficient thickness
relative to (e.g., sufficient height or depth into, etc.) the
nipple 608 and/or at an acute angle relative to a direction of
travel of the light 624 so as to increase the light
transmissibility and/or accentuation of the indicia 620 and/or
allow the indicia 620 to alter (e.g., capture, refract, disperse,
diffuse, diffract, etc.) light 624.
[0081] The nipple 608 may have means for inhibiting light from
inadvertently escaping out of the nipple 608. For example, the
nipple 608 may be configured (e.g., shaped, sized, have opaque
portions, formed of suitable materials, etc.) so as to at least
help direct light through the nipple 608 and/or towards the indicia
620. In this exemplary manner, the amount of light available for
highlighting the indicia 620 can be increased.
[0082] FIGS. 7A and 7B illustrate a lighted receptacle 700
embodying several aspects of the invention. The lighted receptacle
700 is sized to receive a beverage container, such as a beer can
764, beer bottle, a beverage glass, cup, etc. At least a portion
716 of the lighted receptacle 700 is light-transmissive and defines
one or more indicia 720 (e.g., "CARL'S BEER", etc.).
[0083] The indicia 720 can be positioned so as to accentuate
certain portions of the beverage container. For example, the
indicia 720 can be positioned to accentuate or draw attention to
the brewery name or brand of beer on a preexisting label attached
to the beer can 764. In this exemplary manner, the lighted
receptacle 700 and highlighted indicia 720 can serve an advertising
purpose for the brewery name or brand of beer.
[0084] As shown, the lighted receptacle 700 includes four LEDs 712,
although other quantities of LEDs and/or other suitable light
source types can be employed. The LEDs 712 are switchably
connectable with at least one power source 740 (e.g., a watch
battery, etc.) within a power source compartment 736 defined by a
bottom portion 768 of the lighted receptacle 700. Alternatively,
the power source compartment 736 can be defined by other portions
of the lighted receptacle.
[0085] When connected to the power source 740, the LEDs 712 emit
light which highlights the indicia 720. Light from the LEDs 712 can
be guided or conducted by the receptacle sidewalls 772 and 774 such
that the light travels generally upwardly between the sidewalls 772
and 774. The indicia 720 may be formed with a sufficient thickness
relative to (e.g., height or depth into, etc.) the receptacle 700
and/or at an angle relative to a direction of travel of the light
so as to increase the light transmissibility and/or accentuation of
the indicia 720 and/or to allow indicia 720 to alter (e.g.,
capture, refract, disperse, diffuse, diffract, etc.) light from the
LEDs 712.
[0086] Portions of the sidewalls 772 and 774 adjacent the
light-transmissive portion 716 may have means for inhibiting light
from inadvertently escaping out of those portions of the sidewalls
772 and 774. For example, portions of the sidewalls 772 and 774 may
be substantially opaque, reflective, faceted, etc. in order to help
guide light generally upwardly between the sidewalls 772 and 774
and/or towards the indicia 720. Additionally, or alternatively, the
sidewalls 772 and 774 can be configured (e.g., shaped, sized, and
formed of suitable materials, etc.) so that the sidewalls 772 and
774 cooperate to guide or conduct light generally between the
sidewalls 772 and 774, for example, by successive internal
reflections. Accordingly, the selection of material(s) for the
receptacle 700 and its sidewalls 772 and 774 can depend at least in
part on the material's ability to channel or transmit light from
the LEDS 712 generally between the sidewalls 772 and 774 and/or the
material's ability to at least reduce the amount of light that
inadvertently escapes from within the sidewalls 772 and 774. This,
in turn, can increase the amount of available light for
highlighting the indicia 720.
[0087] A wide range of materials, preferably light-weight and
thermally-insulating (for example, to help keep a beverage cool
while it is being consumed) can be used for the receptacle 700.
Further, the same materials do not have to be used for the
light-transmissive portion 716 and the other receptacle portions.
Exemplary materials that can be used for the receptacle 700 include
transparent materials, translucent materials, other light-altering
materials (e.g., materials that alter light by refraction,
diffraction, diffusion, and/or dispersion, etc.), flexible
materials, plastic materials, vinyl materials, polystyrene,
polyvinylchloride (PVC) (e.g., environmentally PVC, medical grade
PVC, etc.) and materials capable of being mass produced with
relatively low manufacturing costs, among other materials suitable
for the intended purpose. The type of material used for the
receptacle 700 may depend at least in part on the particular type
and intensity of light produced by the light source.
[0088] In some embodiments, light from the LEDs 712 can also pass
through the receptacle 700 into a transparent or translucent
beverage container (e.g., beer or soda bottle, etc.) at least
partially positioned within the receptacle 700.
[0089] In this exemplary manner, the beverage within the beverage
container may be illuminated with light emitted by the LEDs
712.
[0090] The lighted receptacle 700 can also include an externally
flexible surface portion 752, such as a flexible bottom portion,
and at least one switching device coupled to the externally
flexible surface portion 752. Application of external pressure upon
the externally flexible surface portion activates the switching
device and switchably connects the light sources 712 to the power
source 740.
[0091] Optionally, one or more of the various LEDs 712 may produce
light that has at least one attribute (e.g., color, intensity,
blink speed, hue, saturation, brightness, etc.) different than the
light produced by the other LEDs 712. By way of example, one or
more LEDs 712 may produce blue-colored light, whereas the other
LEDs 712 may produce red-colored light, among other colors and
color combinations. Rather than producing colored light, one or
more of the LEDs 712 can produce broadband light that travels
through a colored filter, which may but need not be the
light-transmissive portion 716.
[0092] The receptacle 700 can also define a cavity therein. For
example, a cavity may be defined between the inner walls 772 and
outer walls 774 of the receptacle 700. Filler may be disposed
within the cavity. This filler can be adapted to retain heat when
the receptacle is heated and/or retain cold when the receptacle is
cooled. Exemplary fillers include commercially available materials
bearing cold-retaining and/or heat-retaining properties such as,
but not limited to, materials generally used in re-usable
ice-packs, re-usable heating pads, hot/cold gel packs, single-use
hand and toe warmers, among other suitable known (and presently
unknown) materials.
[0093] Additionally, light-altering particles (e.g., glitter,
reflective particles, refractive particles, translucent particles,
glass-like prisms, colored particles, clear particles, etc.) may be
disposed within the cavity defined by the receptacle 700, with or
without the filler. For example, light-altering particles may be
suspended within a hot/cold gel or other suitable substance within
the cavity. Or, for example, light-altering particles may be
contained within a separate container (e.g., tube having etched
sidewalls, etc.), which, in turn, is suspended by a filler within
the cavity. The light-altering particles can receive and alter
light from a light source to create a visibly pleasing or sparkling
light effect. Light-altering particles can also be used with other
embodiments of the invention including the embodiments shown in
FIGS. 1-6 and 8-12).
[0094] FIGS. 8A and 8B illustrate a lighted label 800 embodying
several aspects of the invention. The lighted label 800 is adapted
to be coupled to a beverage container, such as a beer bottle 878.
In an exemplary embodiment, a back surface 882 of the label 800 has
an adhesive thereon which is suitable for attaching the label 800
to a glass bottle, although other suitable attachment means can
also be employed. The light label 800 can be disposable or
reusable.
[0095] At least a portion 816 of the lighted label 800 is
light-transmissive and defines one or more indicia 820. For
example, the indicia 820 may include a person's name (e.g., "CARL'S
BEER", etc.) to allow that person's drink to be readily identified,
for example, from a group of other drinks on a table. The indicia
820 can also be positioned so as to accentuate certain portions of
the beverage container. For example, the indicia 820 can be
positioned to accentuate or draw attention to the brewery name or
brand of beer on a preexisting label attached to the beer bottle
878. In this exemplary manner, the lighted label 800 and
highlighted indicia 820 can serve an advertising purpose for the
brewery name or brand of beer.
[0096] As shown, the lighted label 800 includes two LEDs 812,
although other quantities of LEDs and/or other suitable light
source types can be employed. The LEDs 812 are switchably
connectable with at least one power source 840 (e.g., a watch
battery, etc.) within a power source compartment 836 defined by the
lighted label 800.
[0097] When connected to the power source 840, the LEDs 812 emit
light 824 which highlights the indicia 820. The indicia 820 may be
formed with a sufficient thickness relative to (e.g., height or
depth into, etc.) the label 800 and/or at an angle relative to a
direction of travel of the light 824 so as to increase the light
transmissibility or accentuation of the indicia 820 and/or to allow
the indicia 820 to alter (e.g., capture, refract, disperse,
diffuse, diffract, etc.) light 824.
[0098] The label 800 may have means for inhibiting light from
inadvertently escaping out of the label 800. For example, the label
800 may be configured (e.g., shaped, sized, have opaque portions,
formed of suitable materials, etc.) so as to at least help direct
light through the label 800 and/or towards the indicia 820. In this
exemplary manner, the amount of light available for highlighting
the indicia 820 can be increased.
[0099] In some embodiments, the back portion 882 of the label 800
is transparent or translucent such that light 824 from the LEDs 812
can pass into a transparent or translucent beverage container to
which the label 800 is attached. In this exemplary manner, the
beverage within the beverage container can also be illuminated with
light emitted by the LEDs 812.
[0100] The lighted label 800 can also include an externally
flexible surface portion, for example a flexible back portion 882,
and at least one switching device coupled to the externally
flexible surface portion. Application of external pressure upon the
externally flexible surface portion activates the switching device.
This, in turn, electrically connects the LEDs 812 to the power
source 840. Alternatively, other switching means can also be
employed for the lighted label 800.
[0101] Optionally, one or more of the various LEDs 812 may produce
light that has at least one attribute (e.g., color, intensity,
blink speed, hue, saturation, brightness, etc.) different than the
light produced by the other LEDs 812. By way of example, one or
more LEDs 812 may produce blue-colored light, whereas the other
LEDs 812 may produce red-colored light, among other colors and
color combinations. Rather than producing colored light, one or
more of the LEDs 812 could produce broadband light that travels
through a colored filter, which may but need not be the
light-transmissive portion 816.
[0102] In some embodiments, the label's back portion 882 (or other
label portion) may include a graphic element or image (e.g., a
scene, printed material, a photograph, artwork, an art print, a
photographic print, etc.) which may but need not be
ultraviolet-reactive (e.g., responsive to the ultraviolet A (UVA)
radiation component of black light, etc.). The indicia 820 can be
positioned relative to the graphic element to accentuate certain
portions of the graphic element when the indicia 820 are
highlighted. Further, some embodiments include indicia 820 formed
with ultraviolet-reactive ink (e.g., ink responsive to the UVA
component of black light, etc.) and/or an ultraviolet-reactive
light-transmissive portion 816. In which case, the light source 812
is preferably adapted to produce and direct ultraviolet light
(e.g., black light which includes a UVA radiation component, etc.)
at the indicia 820, light-transmissive portion 816, and the graphic
element.
[0103] FIGS. 9 and 10 illustrate a lighted key holder 900 embodying
several aspects of the invention. As shown, the lighted key holder
900 includes a housing 983 which defines an internal compartment
984 adapted to receive a back portion 985 of a key 986. At least a
portion 916 of the housing 983 is light-transmissive and defines
one or more indicia 920.
[0104] In an exemplary embodiment, the indicia 920 is etched or
carved (e.g., with a cutting tool, knife, razor blade, laser,
chemically etched, drilled, etc.) into the material (e.g., plastic,
etc.) forming the key holder 900. This etching can increase the
light transmissibility of the etched indicia and/or allow the
etched indicia to alter (e.g., capture, refract, disperse, diffuse,
diffract, etc.) light 924. The preferred angle(s) and thickness
(e.g., height or depth, etc.) at which the indicia are cut or
otherwise formed into the key holder material will depend on the
particular application. In exemplary embodiments, the indicia can
be etched into an outer and/or inner surface of the key holder
material at an angle of about +/-45 degrees relative to the
direction of travel of the light 924.
[0105] As shown, the lighted key holder 900 includes two LEDs 912,
although other quantities of LEDs and/or other suitable light
source types can be employed. The LEDs 912 are switchably
connectable via conductive leads 944 with at least one power source
940 (e.g., a watch battery, etc.) within a power source compartment
936 defined by the lighted key holder 900.
[0106] When connected to the power source 940, the LEDs 912 emit
light 924 which highlights the indicia 920. The light 924 can be
guided or conducted by the housing 983 such that the light travels
generally towards the indicia 920 and/or a front portion 987 of the
housing 983. In at least some embodiments, the front portion 987 is
transparent (or at least translucent) such that light 924' can pass
therethrough. In this exemplary manner, a key portion 988 extending
outwardly from the housing 983 (and a keyhole adjacent thereto) can
be illuminated with light 924' emitted by the LEDs 912.
[0107] The key holder 900 may have means for inhibiting light from
inadvertently escaping out of the label 800. For example, the key
holder 900 may be configured (e.g., shaped, sized, have opaque
portions, formed of suitable materials, etc.) so as to at least
help direct light 924 generally towards the front portion 987
and/or the indicia 920. This, in turn, can increase the amount of
available light for highlighting the indicia 920 and/or for
illuminating the key portion 988.
[0108] The housing 983 can include an externally flexible surface
portion and at least one switching device (e.g., push-button
switching device, etc.) coupled to the externally flexible surface
portion such that application of external pressure upon the
externally flexible surface portion activates the switching device.
This, in turn, switchably connects the LEDs 912 to the power source
940. Alternatively, other switching means can also be employed. For
example, in another embodiment, the key holder includes electrical
terminals external to the housing such that a user's hand upon
grasping the key holder causes electrical contact between the
terminals thus completing the circuit for power delivery to the
light source from the power source.
[0109] To allow a user internal access to the key compartment 984,
for example, to remove or replace the key 986, the key holder 900
includes an openable portion 989, such as a lid or cap. When in the
open position (FIG. 10), the portion 989 exposes the key
compartment 984. But the portion 989 closes the key compartment 984
to retain the key 986 within the housing 983 when the portion 989
is coupled to the housing 983 in a closed position (FIG. 9).
[0110] In the illustrated embodiment of FIGS. 9 and 10, the portion
989 is pivotably or hingedly coupled to the housing 983 such that
the portion 989 is pivotal between an opened position (FIG. 10) and
a closed position (FIG. 9). Alternatively, the portion 989 can be
removably coupled to the housing 983 by using a suitable fastening
system or method (e.g., a threaded connection, an interference fit,
resilient ribs, among others).
[0111] The lighted key holder 900 can also include a loop 990 for
attaching the lighted key holder 900 to a key ring or key chain.
Alternatively, other attachment devices (e.g., magnets, clasps,
hook and loop fasteners, etc.) can also be used for attaching the
key holder 900 to a key ring, key chain, or a user.
[0112] FIG. 11 illustrates a lighted item 1100 embodying several
aspects of the invention. The lighted item 1100 includes a base
portion and a lighted removable portion, which in the illustrated
embodiment are in the form of a placemat 1191 and a lighted coaster
1192, respectively, each having a relatively low profile. The base
portion and the lighted removable portion should not be limited to
the exemplary tablemat and coaster combination shown in FIG. 11 as
these configurations are shown for illustrative purposes only and
not for purposes of limitation.
[0113] With further reference to FIG. 11, indicia 1120 is defined
along a light-transmissive sidewall portion 1116 of the coaster
1192. The indicia 1120 can be formed (e.g., with a cutting tool,
knife, razor blade, laser, chemically etched, drilled, etc.) with a
sufficient thickness relative to (e.g., at a sufficient height or
depth into, etc.) sidewall portion 1116 and/or at an angle relative
to the direction of travel of the light 1124 so as to increase the
light transmissibility and/or accentuation of the indicia 1120 by
the light 1124 and/or to allow the indicia 11 20 to alter (e.g.,
capture, refract, disperse, diffuse, diffract, etc.) light 1124.
Additionally, or alternatively, indicia can be defined in other
methods (e.g., by using optical fibers, etc.) and by other portions
of the coaster 11 92, such as the coaster top surface 11 93.
[0114] The coaster 1192 includes four LEDs 1112, although other
quantities of LEDs and/or other suitable light source types can be
employed. Conductive leads 1144 connect the LEDs 1112 with at least
one power source 1140 (e.g., a watch battery, etc.) within a power
source compartment 1136 defined by the coaster 1192.
[0115] When connected to the power source 1140, the LEDs 1112 emit
light 1124 which highlights the indicia 1120 defined along the
coaster sidewall 1160 and/or elsewhere. The coaster 1192 can be
configured (e.g., shaped, sized, have opaque portions, formed of
suitable materials, etc.) so as to at least help direct light
through the coaster 1192 and/or towards the indicia 1120. In this
exemplary manner, the amount of light available for highlighting
the indicia 1120 can be increased.
[0116] The coaster 1192 is sized to be received within an opening
1194 defined by the placemat 1191. The coaster 1192 may be engaged
with the placemat 1191 using any suitable fastening system or
method (e.g., a threaded connection, an interference fit, resilient
ribs, among others). In one embodiment, the opening 1194 is sized
to frictionally receive and form an interference fit with the
coaster 1192 such that an external force must be applied to the
coaster 1192 to remove the coaster 1192 from the opening 1194. In
this exemplary manner, the coaster 1192 can be retained within the
opening 1194 during normal use. This also allows the coaster 1192
to be readily removed from the opening 1194, for example, to
substitute or replace the coaster 1192 or the placemat 1191.
[0117] In some embodiments, indicia 1120' are also defined along a
light-transmissive sidewall portion 1195 of the placemat 1191. The
indicia 1120' can be formed (e.g., etched, carved, etc.) with a
sufficient thickness relative to (e.g., at a sufficient height or
depth into, etc.) the sidewall portion 1195 and/or at an angle
relative to the direction of travel of the light so as to increase
the light transmissibility and/or accentuation of the indicia 1120'
and/or to allow the indicia 1120' to alter (e.g., capture, refract,
disperse, diffuse, diffract, etc.) light 1124.
[0118] Additionally, or alternatively, indicia can be defined by
other methods (e.g., by using optical fibers, etc.) and by other
portions of the placemat 1191, such as the placemat's top surface
1196.
[0119] When the coaster 1192 is within the placemat opening 1194,
light 11 24 from the LEDs 111 2 passes through the coaster's
sidewall 11 60 and into the placemat 1191. In this exemplary
manner, the placemat indicia 1120' can be illuminated with light
from the LEDs 1112. The placemat 1191 may have means for inhibiting
light from inadvertently escaping out of the placemat 1191. For
example, the placemat 1191 may be configured (e.g., shaped, sized,
have opaque portions, formed of suitable materials, etc.) so as to
at least help direct light through the placemat 1191 and/or towards
the indicia 1120'. In this exemplary manner, the amount of light
available for highlighting the indicia 1120' can be increased.
[0120] Various embodiments can include a plurality of
interchangeable placemats each defining an opening for receiving
the coaster 1192. The placemats can have a variety of sizes,
configurations, shapes, decorations, and define different indicia.
For example, the lighted coaster 1192 may be used in a generally
rectangular placemat decorated with a Christmas motif as well in a
generally oval shaped placemat decorated with a Thanksgiving motif.
In various embodiments, the lighted coaster 1192 can also include a
controller (e.g., an integrated circuit/printed circuit assembly
and at least one switch, etc.) for controlling the operation of the
light sources 1112 such that the lighted coaster 1192 produces
thematic light (e.g., certain colors, etc.) consistent with the
particular theme or motif associated with the placemat. For
example, when the coaster 1192 is being used with a placemat
decorated with a Christmas motif, a user can access the
controller's switch to cause the LEDs 1112 to emit light that
phases between the colors green and red.
[0121] Various embodiments can include a plurality of
interchangeable coasters each sized to be received within an
opening 1194 defined by the placemat 1191. The various lighted
coasters may each define different indicia and/or be decorated
differently. For example, one coaster may be decorated with a
Christmas motif, another can be decorated with a Thanksgiving
motif, and yet another can be decorated in a Halloween motif.
Accordingly, any of these coasters may be used with the placemat
1191 depending on which holiday is being celebrated. In addition,
various embodiments can include coasters that produce thematic
light (e.g., certain colors, etc.) consistent with the particular
theme or motif. For example, a coaster decorated with a Halloween
motif can include one or more LEDs that produce orange and/or black
colored light.
[0122] In at least some embodiments, the coaster 1192 is integral
with and fixedly attached to the placemat 1191. Yet other
embodiments include one or more lighted coasters 1192 but not a
placemat or base portion 1191. Other embodiments include at least
one placemat defining a plurality of openings each sized to receive
a different one of a plurality of lighted coasters.
[0123] In still further embodiments, the coaster and/or placement
(e.g., lower surface, etc.) can include a graphic element or image
thereon (e.g., a scene, printed material, artwork, a graphic
design, a photograph, artwork, an art print, a photographic print,
etc.). The indicia can be positioned relative to the image such
that the indicia when highlighted accentuate certain portions of
the graphic element or image. For example, the coaster and/or
placement can include a menu thereon such that the light and/or
highlighted indicia accentuate prices on the menu.
[0124] FIGS. 12A, 12B, and 12C respectively illustrate a lighted
fork 1200A, spoon 1200B, and knife 1200C embodying several aspects
of the invention. As shown, each lighted item 1200 includes a
handle 1204 and an LED 1212 within the handle 1204. Alternatively,
other quantities of LEDs and/or other suitable light source types
can be employed. The LED 1212 is switchably connectable via
conductive leads 1244 with at least one power source 1240 (e.g., a
watch battery, etc.) also disposed within the handle 1204.
[0125] When connected to the power source 1240, the LED 1212 emits
light 1224 which highlights the indicia 1220. The light 1224 can be
guided or conducted by the handle 1204 such that the light travels
generally towards the indicia 1220. The indicia 1220 can be formed
with a sufficient thickness relative to (e.g., at a sufficient
height or depth into, etc.) the handle 1204 and/or at an angle
relative to the direction of travel of the light so as to increase
the light transmissibility and/or accentuation of the indicia 1220
and/or to allow indicia 1220 to alter (e.g., capture, refract,
disperse, diffuse, diffract, etc.) light from the LED 1212.
[0126] The handle 1204 may have means for inhibiting light from
inadvertently escaping out of the handle 1204. For example, the
handle 1204 may be configured (e.g., shaped, sized, have opaque
portions, formed of suitable materials, etc.) so as to at least
help direct light 1224 generally towards the indicia 1220. This, in
turn, can increase the amount of available light for highlighting
the indicia 1220 and/or for illuminating adjacent surroundings. For
example, light 1224 from the LED 1212 can illuminate a food item on
the tines 1297A of the fork 1200A, within the bowl portion 1298B of
the spoon 1200B, or being cut by the cutting edge 1299C of the
knife 1200C.
[0127] In FIGS. 12A and 12C, the lighted fork 1200A and knife 1200C
are shown with a rotatable end cap 1248A, 1248C, respectively, that
functions as a switching device for switchably connecting the LED
1212A, 1212C to the power source 1240A, 1240C. Rotating the end cap
1248A, 1248C in a first direction relative to a longitudinal axis
through the handle 1204A, 1204C activates or turns on the LED
1212A, 1212C. Rotating the end cap 1248A, 1248C in the opposite
direction deactivates or turns off the LED 1212A, 1212C.
[0128] As shown in FIG. 12B, the lighted spoon 1200B includes
electrical terminals 1248B externally located on the handle 1204B
such that a user's hand upon grasping the spoon handle 1204 causes
electrical contact between the terminals 1248B, thereby completing
the circuit for power delivery to the LED 1212B from the power
source 1240B. Alternatively, the terminals 1248B may be located at
other positions. In addition, other switching means can be employed
for the lighted tableware including push-button switches, etc.
[0129] In various embodiments, the lighted item can include an
ultraviolet-reactive portion, and the light source can include at
least one ultraviolet light source for illuminating the
ultraviolet-reactive portion with ultraviolet light. For example,
the ultraviolet-reactive portion can be responsive to the
ultraviolet A (UVA) radiation component of black light produced by
the light source, which, in turn, produces a visually stimulating
effect. Exemplary ultraviolet-reactive materials include plastic or
vinyl materials containing phosphor (e.g., Zinc Sulfide, Strontium
Aluminate, etc.) and fluorescent materials.
[0130] Further, the indicia in various embodiments can be formed
with ultraviolet-reactive ink. Accordingly, the lighted item can
include one or more indicia which are responsive to ultraviolet
light, such as the UVA component of black light.
[0131] Indeed, some embodiments of the lighted item include an
outer light-transmissive layer which can be reactive to ultraviolet
light (e.g., responsive to the UVA component of black light, etc.),
indicia formed with ultraviolet-reactive ink, and an inner or back
layer including a graphic element or image thereon (e.g., a scene,
printed material, artwork, a graphic design, a photograph, artwork,
an art print, a photographic print, etc.) which can also be
ultraviolet-reactive. In such embodiments, the light source can
produce and direct ultraviolet light (e.g., black light with an UVA
radiation component, etc.) at the indicia and the inner and outer
layers to produce a visually pleasing display. The indicia can be
positioned relative to the graphic element to accentuate certain
portions of the graphic element when the indicia are
highlighted.
[0132] Moreover, in any of the embodiments in which the lighted
item includes an edible (e.g., edible portion 108 of the frozen
confection 100, candy 208, etc.), the edible (or a portion thereof)
may itself be UV-reactive or responsive to black light. For
example, various embodiments include an edible including a
UV-reactive food additive.
[0133] In various embodiments of the invention, a wide range of
materials can be used for the lighted item. The indicia can be
integrally formed into the material by using a cutting tool, knife,
razor blade, laser, chemically etched, drilled, etc. Exemplary
materials include transparent materials, translucent materials,
other light-altering materials (e.g., materials that alter light by
refraction, diffraction, diffusion, and/or dispersion, etc.),
flexible materials, plastic materials, vinyl materials,
polystyrene, polyvinylchloride (PVC) (e.g., environmentally PVC,
medical grade PVC, etc.) and materials capable of being mass
produced with relatively low manufacturing costs, among other
materials suitable for the intended purpose. The type of material
used can depend at least in part on the particular type and
intensity of light produced by the light source. Alternatively, or
additionally, a light-transmissive portion may be defined by one or
more openings or holes which are arranged to form indicia. These
holes allow light from the light source to escape or pass through
the holes, thus becoming visible to a user.
[0134] In various embodiments of the invention, a lighted item can
include any suitable number of (i.e., one or more) and type of
light source. Exemplary light sources include LEDs, incandescent,
laser, fluorescent, phosphorescent, chemiluminescent, halogen,
fiber optics, electroluminescent, neon light sources, black lights,
a combination thereof, and the like.
[0135] In various embodiments of the invention, a lighted item can
include a plurality of light sources, one or more of which may
produce light having at least one attribute (e.g., color,
intensity, blink speed, hue, saturation, brightness, etc.)
different than light produced by another light source. Indeed, any
of the various lighted items 100, 200, 300, 400, 500, 600, 700,
800, 900, 1100, 1200 can be configured to produce light having one
or more colors depending at least in part on user preferences. User
preferences may, in turn, be based on any number of factors
including the event at which the lighted item is being distributed
or used. For example, a lighted item which produces colored light
consistent with a home team's colors can be distributed at a
sporting event, such as a football game.
[0136] In various embodiments of the invention, a lighted item may
include a controller for controlling operation of the light
source(s) in accordance with user input to provide such features as
blinking, strobing and/or color changes. The controller can include
an integrated circuit/printed circuit assembly (e.g., integrated
circuits in a printed circuit assembly, etc.) and at least one
switch. The switch may, for example, allow the user to select from
among various display modes for the light sources, such as an
off-light mode, an on-light mode, a mode in which each of the light
sources simultaneously emit steady or non-flashing light, a mode in
which the light sources emit light intermittently, a mode in which
the various light sources illuminate or blink at different times in
accordance with a predetermined sequence or order, a mode in which
the light sources emit light that phases between or blends colors,
a mode in which the light sources emit light randomly, a mode in
which the light sources pulsate to sounds, and/or a mode combining
one or more of the foregoing. Such sounds may be produced by the
lighted item itself (e.g., via a speaker built-in to the lighted
item, etc.) or a source external to the lighted item (e.g., ambient
sounds, etc.). In some embodiments, sounds can cause synchronized
pulsation of the light sources of two or more different lighted
items, thus providing a pleasing light pattern or effect.
[0137] The controller can also include a plurality of switches each
of which can be used to control the operation of an individual
light source or group of light sources. For example, the controller
may include a first switch for activating and deactivating LEDs
that emit white light and a second switch for activating and
deactivating the LEDs that emit blue light.
[0138] Additionally, various lighted items can include a
push-button switch for switchably connecting the light sources to
the power source. The switch can be positioned within the lighted
item and be coupled to an externally flexible surface portion of
the lighted item such that application of external pressure upon
the externally flexible surface portion activates the switch,
thereby causing operation of the light source. The external
pressure may, for example, be applied by the user squeezing the
lighted item at the externally flexible surface portion. The switch
may also allow the user to cycle through various display modes or
select a particular color for the light by successively squeezing
the lighted item at about the externally flexible surface portion.
Additionally, the switch may also allow the user to dim or brighten
the intensity of the light, for example, by holding down the switch
with continuously applied pressure to the lighted item at about the
externally flexible surface portion.
[0139] Various lighted items can include electrical terminals for
switchably connecting the light source to the power source. For
example, the electrical terminals can be located such that a user's
hand upon grasping the item completes the circuit for power
delivery to the light source from the power source.
[0140] In another form, the present invention provides a method
that generally includes providing a lighted item having at least a
first light-transmissive portion defining one or more indicia, and
at least one light source positioned for directing light through
the first light-transmissive portion for highlighting the indicia.
The method can further include activating the light source to
highlight the indicia.
[0141] In another implementation, a method generally includes
activating at least one light source coupled to an item to
highlight one or more indicia defined by at least a first
light-transmissive portion of the item.
[0142] In yet another form, the invention also provides methods of
advertising. In one implementation, a method of advertising
generally includes distributing at least one item having at least a
first light-transmissive portion defining an advertisement, and at
least one light source positioned for directing light through the
first light-transmissive portion for highlighting the
advertisement. The method can further include activating the light
source to highlight the advertisement. The advertising may include,
e.g., indicia identifying a source (e.g., company, another party,
contact information, etc.) of products or services, such as
trademarks and trade names.
[0143] By highlighting the indicia in a visually stimulating and
pleasing manner, various embodiments of the invention serve to
reinforce or strengthen the effectiveness of the advertisement(s)
being displayed by the item.
[0144] Optionally, the method may also include providing items
having indicia (e.g., branded goods, etc.) for further distribution
(e.g., as a promotional item, etc.) by the source or another party.
In such a case, the method may also include providing the source
(e.g., company, etc.) or another party with items having indicia.
The source, or the another party on behalf of the source, may then
further distribute the items to potential or existing customers of
the products or services provided by the source.
[0145] Certain terminology is used herein for purposes of reference
only, and thus is not intended to be limiting. For example, terms
such as "upper", "lower", "above", and "below" refer to directions
in the drawings to which reference is made. Terms such as "front",
"back", "rear", "bottom" and "side", describe the orientation of
portions of the component within a consistent but arbitrary frame
of reference which is made clear by reference to the text and the
associated drawings describing the component under discussion. Such
terminology may include the words specifically mentioned above,
derivatives thereof, and words of similar import. Similarly, the
terms "first", "second" and other such numerical terms referring to
structures do not imply a sequence or order unless clearly
indicated by the context.
[0146] When introducing elements or features and the exemplary
embodiments, the articles "a", "an", "the" and "said" are intended
to mean that there are one or more of such elements or features.
The terms "comprising", "including" and "having" are intended to be
inclusive and mean that there may be additional elements or
features other than those specifically noted. It is further to be
understood that the method steps, processes, and operations
described herein are not to be construed as necessarily requiring
their performance in the particular order discussed or illustrated,
unless specifically identified as an order of performance. It is
also to be understood that additional or alternative steps may be
employed.
[0147] The description of the invention is merely exemplary in
nature and is in no way intended to limit the invention, its
application, or uses. Thus, variations that do not depart from the
substance of the invention are intended to be within the scope of
the invention. Such variations are not to be regarded as a
departure from the spirit and scope of the invention.
