Description
TECHNICAL FIELD
[0001] The present invention relates to an electromagnetic
radiation assembly, and more specifically to an assembly which may
operate as a combined warning lamp and rearview mirror and which is
operable to illuminate regions adjacent to the overland vehicle and
which assists in the safe operation of the overland vehicle as by
signaling adjacent vehicles of the intention of the operator to
change the direction of the overland vehicle; to assist the
operator in entering or departing the vehicle during reduced
periods of visibility; and further to provide information of
interest, to the operator of the overland vehicle.
BACKGROUND OF THE INVENTION
[0002] The prior art is replete with numerous examples of various
auxiliary signaling assemblies which have been employed for various
purposes on overland vehicles of assorted designs. As a general
matter, these auxiliary signaling assemblies have utilized assorted
semitransparent mirrors including dichroic and electrochromic type
mirrors as well as neutrally chromatic mirrors which have been
modified, in various fashions, so as to be rendered
semitransparent.
[0003] In addition to the use of various semitransparent mirrors,
assorted mirror housing modifications have been made which have
added operational features to these same signaling assemblies. The
modifications have included such things as exterior lamps which
have been useful for illuminating the side of the vehicle, or the
underlying earth beside the vehicle, in order to provide assistance
to an operator when they are leaving or entering the vehicle during
reduced periods of visibility. Auxiliary signaling assemblies such
as found in U.S. Pat. Nos. 5,014,167; 6,005,724; and 6,076,948 for
example have found wide acceptance and are now found on various
overland vehicles including passenger cars, sport utility vehicles,
trucks, and motorcycles.
[0004] In view of the increased commercial acceptance of such
devices, designers have increasingly focused on both interior and
exterior mirrors as regions in which various warning lamps or
indicators may be located so as to provide periodic information to
the operator regarding the operational condition of the overland
vehicle, or other conditions such as ambient environmental
conditions which could effect the safe operation of the overland
vehicle. Such warning lamps and indicators have provided such
information as tire pressure, temperature, and proximity to fixed
objects which may be impacted when the vehicle is being operated in
reverse, for example.
[0005] While the various auxiliary signaling assemblies and
mirrors, as referenced above, have operated with a great deal of
success, there have been shortcomings which have detracted from
their individual usefulness. For example, many of the prior art
designs are quite complex. For example, several of the prior art
auxiliary signaling assemblies which have been utilized heretofore
have resulted in an increase in the size of the exterior mirror
housing in order to accommodate the auxiliary signaling lamps. In
other arrangements, the addition of the auxiliary signaling
assemblies has resulted in an increase in the complexity of the
electrical conduits that are necessary to provide electrical power
to the various assemblies in the mirror. Various solutions have
been suggested to this problem including integrating various
electrical conduits into preexisting mirror assembly components
such as heaters or the like. Notwithstanding these efforts, the
space remaining within a mirror housing is quite limited. With the
continued emphasis on providing increased features which are
available to the operator from the rear and side view mirrors,
problems begin to arise with respect to the dissipation of heat
energy generated as a result of the energizing of various light
emitting diodes which are utilized to provide the visibly
discernable light which can be discerned by the operator of the
overland vehicle. Failure to dissipate excessive amounts of this
heat energy can result in a shortened operational lifetime for
these same assemblies.
[0006] In the present invention, the inventors have departed from
the teachings of the prior art by providing an electromagnetic
radiation assembly which can achieve all the benefits provided by
the previous prior art assemblies while avoiding many of the
shortcomings associated therewith.
[0007] These and other aspects of the present invention will be
discussed in greater detail hereinafter.

relates to an electromagnetic radiation assembly which includes a
first supporting substrate having first and second surfaces, and
which further has a region through which an electromagnetic
radiation signal may pass; a first plurality of electromagnetic

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] This disclosure of the invention is submitted in furtherance
of the constitutional purposes of the U.S. Patent Laws "to promote
the progress of science and useful arts" (Article 1, Section
8).
[0023] Referring more particularly to the drawings, the
electromagnetic radiation assembly of the present invention is
generally indicated by the numeral 10 in FIG. 1 and following. For
illustrative convenience the electromagnetic radiation assembly 10
of the present invention, and which is shown and described herein,
is discussed as it would be configured if it were installed on an
overland vehicle 11 of conventional design and which is best seen
by reference to FIG. 8. As discussed in many of the earlier prior
art patents, the electromagnetic radiation assembly (hereinafter
referred to as assembly 10) of the present invention operates as a
combination rearview mirror, and visual signaling device, and
wherein the visual signaling device provides a visual signal or
pattern of illumination which is capable of being perceived from
various locations which are located in assorted different
directions which are laterally outwardly, inwardly, and rearwardly
of the overland vehicle, when the invention is operating in its
several operational modes. As will be discussed in greater detail
hereinafter, the present assembly 10 is operable to generate
visibly discernable electromagnetic radiation which can be seen as
illustrated in FIG. 8A at locations laterally outwardly relative to
the overland vehicle 11; laterally inwardly relative to the
overland vehicle as seen in FIG. 8B; and rearwardly and downwardly
as seen in FIG. 8C. Other emission patterns are also possible.
These various modes of operation of the assembly 10 will be
discussed in greater detail hereinafter.
[0024] As seen in FIG. 8, the present invention 10 is mounted on an
overland vehicle 11 of conventional design. The overland vehicle 11
has a front or forward portion 12, and a rearward portion 13. The
overland vehicle 11 further has a passenger compartment 14 where an
operator of the overland vehicle is seated. Still further, the
overland vehicle includes exterior locations 21 for a pair of
exterior rearview mirrors which incorporate the present invention
and which are best understood by a study of FIGS. 1 and 7,
respectively. These forms of the invention will be discussed in
greater detail below. As should be understood, the overland vehicle
11 also has a hand operated directional signaling switch; and foot
brake (not shown), and which when utilized, provides an electrical
signal which may alert drivers of other vehicles in the immediate
vicinity that the overland vehicle 11 is about to change
directions, turn, change lanes, etc. Yet further, other signals or
warning icons may also be provided, and which can be viewed from
the overland vehicle and which will alert the operator of various
conditions existing on the overland vehicle, or outside ambient
environmental conditions which may effect the safe operation of the
overland vehicle. In addition to the foregoing, the overland
vehicle 11 may be equipped with a radio frequency receiver 22 and
which receives an RF signal which is transmitted from a key fob
held by the operator of the overland vehicle (not shown). This RF
signal, once received, is effective to unlock the various doors of
the overland vehicle and further is useful in actuating the
operation of the assembly 10 in one of its several modes of
operation, as will be discussed below.
[0025] As best illustrated in FIG. 8, an operator of an overland
vehicle 11 when positioned in the operator's position 20 has a
field of view which extends approximately 180.degree. from the
operator's position towards the forward portion 12 of the vehicle.
Further, and by using a pair of the assemblies 10 which are
individually located at the positions 21 on the exterior portion of
the overland vehicle 11, the operator may, by looking along given
lines of sight, view rearwardly of the vehicle along the driver's
side, passenger side, and substantially along a longitudinal axis
23 of the overland vehicle 11 when the operator views an interior
rearview mirror, which is not shown. As depicted in FIGS. 8A, B and
C, the assembly 10 of the present invention, when energized,
provides a plurality of illumination zones which are generally
indicated by the numeral 30. These illumination zones include a
first illumination zone 31 (FIG. 8A) which provides visibly
discernable electromagnetic radiation which is visible at positions
which are laterally, outwardly relative to the intended direction
of travel of the overland vehicle 11. This first illumination zone
is designed to direct visibly discernable electromagnetic radiation
at vehicles traveling rearwardly and in adjacent lanes relative to
the overland vehicle 11 when the apparatus is operating in a first
mode. Still further, the second illumination zone 32 provides
visibly discernable electromagnetic radiation which is oriented
substantially laterally, inwardly relative to the direction of
movement of the overland vehicle, and which can be perceived by the
operator of same when the apparatus is operating in a second mode.
Typically, this second illumination zone is employed to transmit
information of interest to the operator of the overland vehicle 11
regarding the operational conditions of the overland vehicle 11 as
well as other information which may be of interest in the safe
operation of the overland vehicle 11. Still further, the assembly
10, when energized, provides a third illumination zone 33 which is
oriented substantially laterally inwardly, and downwardly towards
the face of the earth when the apparatus is operating in a third
mode. The third illumination zone is utilized typically for
purposes of illuminating the side and region adjacent to the
overland vehicle during periods of reduced visibility in order for
an operator to safely enter or exit the overland vehicle. These
various illumination zones will be discussed in greater detail
hereinafter.
[0026] Referring now to FIG. 1, the first form of the assembly 10
of the present invention is incorporated into a mirror housing
which is generally indicated by the numeral 40, and which is
typically mounted at the mirror locations 21 on the exterior
surface of the overland vehicle 11. The mirror housing or enclosure
has a rear wall 41, and a sidewall 42 extends outwardly therefrom.
The sidewall 42 has a peripheral edge 43 and which defines an
aperture 44 having given dimensions. The rear wall 41, and sidewall
42 further defines a cavity 45 which receives and encloses the
assembly 10, and other associated devices such as a movable bezel,
which is not shown. As should be understood, the bezel may also
include a cavity which matingly receives, at least in part, the
assembly 10. The bezel movably supports the assembly 10 within the
housing 40. The assembly 10 can be positionally adjusted either
manually, or remotely, by an actuator (not shown) to a given
angular orientation relative to the various lines of sight utilized
by the operator (not shown) of the overland vehicle 11. This
movement of the assembly provides a means by which the operator may
adjust his given field of view rearwardly of the overland vehicle
11.
[0027] The assembly 10 of the present invention, as seen in FIG. 1
and following, includes a semitransparent substrate which is
generally indicated by the numeral 50, and which has a front, first
or outside facing surface 51, and an opposite, second or rearwardly
facing surface 52. In automotive applications, the semitransparent
substrate is a semitransparent mirror which is selected from the
group of semitransparent mirrors comprising substantially neutrally
chromatic; dichroic; electrochromic and/or combinations thereof.
The semitransparent substrate or mirror 50 further is defined by a
peripheral edge 53, which substantially corresponds in shape and in
size to the aperture 44 which is defined by the peripheral edge 43
of the housing 40. When assembled, the semitransparent mirror or
substrate 50 substantially occludes the aperture 44. The
semitransparent substrate or mirror 50 of the present invention may
take on several forms. As seen in FIGS. 1 and 7, the
semitransparent substrate or mirror typically comprises a
substantially transparent or translucent substrate which has a
highly reflective coating applied thereto. As should be understood,
the reflective coating may be applied, either, on the one hand, to
the first or outside facing surface 51, or in the alternative, and
more typically to the opposite, second or rearwardly facing surface
52. The highly reflective coating may comprise any number of
different highly reflective or mirror like coatings or substances
such as chromium and the like, and which may be applied or formed
in a manner which provides a commercially acceptable reflective
surface. Still further, other coatings may be applied, for example,
to the opposite rearwardly facing surface 52 such as masking layers
and the like and which render the semitransparent substrate or
mirror substantially opaque. For automotive applications, the
resulting reflectance of the semitransparent mirror or substrate 50
should be generally, on average, greater than about 35%. However,
in other commercial applications, increased or decreased
reflectance may be acceptable depending upon the end use of the
assembly 10.
[0028] As best seen in FIGS. 1 and 7, for example, the
semitransparent substrate or mirror 50 has a first, or primary
region 61, and through which a visibly discernable electromagnetic
radiation signal may pass; and an adjacent secondary region 62.
While only two regions are shown and discussed herein, it is of
course possible to have a plurality of secondary regions depending
upon the end use of the assembly 10. These secondary regions may be
adjacent to each other, or may be spaced at a distance and
positioned at various locations about the semitransparent substrate
or mirror 50. As a general matter, however, the first or primary
region 61 passes a portion of the visibly discernable
electromagnetic radiation directed at same while simultaneously
reflecting a given percentage of the visibly discernable
electromagnetic radiation or light which comes from the ambient
environment. On the other hand, the secondary region 62 is operable
to reflect ambient visibly discernable electromagnetic radiation
and is otherwise considered nominally opaque. Depending upon the
reflective or other masking layers which are applied to the
opposite, rearwardly facing surface 52, the secondary region 62 may
be considered completely opaque. As discussed above, the combined
average reflectance of the overall surface area of the
semitransparent substrate or mirror 50, including both the primary
and secondary regions, is typically greater than about 35% when the
assembly 10 is being employed for automotive applications, as noted
above. In other industrial applications, the average reflectance
may be lower or higher depending upon the desired end use. As seen
in the drawings, the secondary region 62 is substantially
continuous and reflects for automotive applications greater than
about 35% of the ambient, visible, electromagnetic radiation, and
which strikes the first outside facing surface 51 thereof.
Typically, in most automotive applications, the secondary region
62, on average, passes less than about 10% of the ambient visibly
discernable electromagnetic radiation. The first or primary region
61, on the other hand, passes less than about 50% of visible
electromagnetic radiation, and further reflects on average, less
than about 40% of visible electromagnetic radiation. The ranges
noted above have been found suitable for automotive applications,
however, it will be recognized that other broadened or narrowed
ranges may be useful for other industrial applications.
[0029] As seen in FIG. 1, the semitransparent mirror 50 includes a
plurality of discrete apertures or regions 63 which may be formed
in a given pattern, and in various densities in the reflective
coating, and which facilitates the passage of visibly discernable
electromagnetic radiation therethrough. With respect to the
semitransparent mirror or substrate 50, the first or primary region
61 may be formed by a number of different means including providing
reduced thickness areas in the associated reflective coating which
is provided. These reduced thickness areas in the mirror coating
allow increased amounts of visibly discernable electromagnetic
radiation to pass therethrough in relative comparison to the
adjacent thicker areas in the secondary region 62. Further, the
secondary region, as earlier discussed, may be coated with an
opaque masking layer which substantially inhibits visibly
discernable electromagnetic radiation from passing therethrough.
Still further, the semitransparent mirror or substrate 50 may have
a dichroic mirror coating applied thereto. The usefulness of
dichroic mirror coatings of various types have been discussed in
various U.S. patents including U.S. Pat. Nos. 5,014,167 and
5,207,492 to name but a few. These dichroic mirror coatings are
well known in the art, and further discussion regarding the nature
and operation of these respective mirror coatings is not warranted.
In connection with such dichroic mirror coatings, a substantially
opaque masking layer, as earlier discussed, may be applied over the
secondary region 62 thereby making the secondary region
substantially opaque and further permitting visible electromagnetic
radiation to pass through the first or primary region 61 which is
unmasked. As discussed in the earlier prior art patents, the
dichroic mirror coating which is applied to the semitransparent
mirror or substrate 50 may be selected to pass given bands of
visibly discernable electromagnetic radiation or light in greater
amounts than other bands of electromagnetic radiation thereby
making the resulting semitransparent mirror or substrate 50, on
average, an acceptable reflector of visibly discernable
electromagnetic radiation while simultaneously allowing increased
amounts of visibly discernable electromagnetic radiation of the
selected band of electromagnetic radiation to pass therethrough. In
addition to the foregoing, another acceptable semitransparent
mirror or substrate 50 may include an electrochromic mirror of a
construction similar to that seen in U.S. Pat. Nos. 6,257,746; and
6,512,624 the teachings of which are incorporated by reference
herein. In view of these teachings, an electrochromic mirror may be
useful in the practice of the present invention 10 as will be
discussed in greater detail below. It is also possible to provide
combined substrates 50 depending upon the end use of the
assembly.
[0030] Referring now to FIG. 1, and following, the assembly 10 of
the present invention includes a first substantially opaque
substrate which is generally indicated by the numeral 70. The first
opaque substrate operates, at least in part, as a circuit board in
order to mount a plurality of electromagnetic radiation emitters
which will be discussed below. The first substrate 70 has a first
surface 71, which is typically juxtaposed relative to the second or
rearwardly facing surface 52 of the semitransparent mirror 50. The
first substrate 70 has a distinct second surface 72. Still further,
the first substrate 70 defines, at least in part, one region 73
(FIG. 1), although a plurality of regions may be defined, and
through which visibly discernable electromagnetic radiation may
pass. As seen, the region through which the electromagnetic
radiation may pass 73 may include a plurality of apertures 74 which
are formed in the first substrate 70 and which extend therethrough.
The apertures 74 are positioned in a predetermined pattern in order
to provide a resulting visual signal which may be viewed and
understood by others at a distance relative to the overland vehicle
11. As seen in FIGS. 1 and 2, the first substantially opaque
substrate 70 mounts on the second surface 72 thereof, a first
plurality of electromagnetic radiation emitters 75. The second
surface 72 also mounts electrically conductive passageways (not
shown), and which electrically couple the respective
electromagnetic radiation emitters 75 with a source of electrical
power which is typically provided by the overland vehicle 11. As
should be understood, the first plurality of electromagnetic
radiation emitters 75, when energized, emit visibly discernable
electromagnetic radiation which travels along a path which is
generally indicated by the numeral 76 (FIGS. 3 and 5), and which
forms the first illumination zone 31, as seen in FIG. 8A. As seen
in FIG. 1, it will be understood that the first plurality of
electromagnetic radiation emitters are mounted on the second
surface 72 of the first opaque substrate 70, and near the region 73
which passes the visibly discernable electromagnetic radiation. As
illustrated in FIG. 1, the individual electromagnetic radiation
emitters are typically associated with the individual apertures 74
which are formed in the first opaque substrate 70. While the
discussion above was directed to visibly discernable
electromagnetic radiation, it is possible by means of the present
invention to emit electromagnetic radiation which is not visible
and which would be useful in other applications.
[0031] Referring now to FIGS. 1, 3 and 4, it will be seen that the
assembly 10 of the present invention includes a reflector which is
generally indicated by the numeral 80. The reflector can be
fabricated by utilizing standard injection molding techniques, and
post, reflective coating procedures. Alternatively, it may be
pressure or vacuum formed from deformable sheets that have a highly
reflective coating formed thereon. The reflector 80 has a first
surface 81 which is positioned near the second surface 72 of the
first opaque substrate 70; and a distinct second surface 82, as
best seen by reference to FIG. 3. In the arrangement as shown in
FIG. 4, it will be seen that the first opaque substrate 70 matingly
cooperates with the reflector 80 such that the reflector 80 is
juxtaposed, at least in part, relative to the semitransparent
mirror or substrate 50. As seen by reference to FIG. 4, it will be
understood that the first plurality of electromagnetic radiation
emitters 75 are positioned near, but in spaced relation relative
to, the first surface 81 of the reflector 80. As best understood by
a study of FIGS. 1 and 3, respectively, the reflector 80 includes a
first portion 83, and a second portion 84. The first portion 83 of
the reflector 80 includes a plurality of individual reflector
pockets 85 which define cavities 86. The individual reflector
pockets 85 are typically positioned in substantially eccentric
reflecting relation relative to the first plurality of
electromagnetic radiation emitters 75. When energized, the
respective reflector pockets individually reflect the visibly
discernable electromagnetic radiation 76 emitted by the first
plurality of electromagnetic radiation emitters 75 in a first
direction, as illustrated, and into the illumination zone 31 as
seen in FIG. 8A. As illustrated in the drawings, the respective
reflector pockets 85 typically include multiple reflector facets
which are generally indicated by the numeral 90. The respective
reflector facets are operable to reflect the emitted visibly
discernable electromagnetic radiation into the illumination zones
as illustrated in FIGS. 8A-C, respectively during the various modes
of operation of the invention. With respect to the second portion
84 of the reflector 80, it should be understood that the second
portion 84 of the reflector 80 comprises, at least in part, an
aperture 91 which extends through the reflector and which allows
visibly discernable electromagnetic radiation generated by a second
electromagnetic radiation emitter, which will be discussed below,
to pass therethrough. The second portion 84 of the reflector
further includes a reflector facet 92 having a reflecting surface
93 (FIG. 5) which is located adjacent to the aperture 91 and which
is further positioned in spaced relation relative to the second
surface 82 of the reflector 80 (FIG. 4), and oriented in reflecting
relation relative to the second electromagnetic radiation emitter
as will be described hereinafter. In the arrangement as seen in
FIG. 3, it will be understood that visibly discernable
electromagnetic radiation emitted by the second electromagnetic
radiation emitter is reflected by the reflector facet 92 of the
second portion 84, and in a second direction where it passes into
the illumination zone 33 as seen in FIG. 8C. As should be noted,
the visibly discernable electromagnetic radiation from both
emitters is passed by the first region 61 of the semitransparent
substrate 50, and viewed at locations forward of the first surface
of the first substrate 70.
[0032] Referring now to FIGS. 1, 3, 4 and 5, it will be seen that
the assembly 10 includes a second supporting substrate 100, and
which is located in spaced relation relative to the first
substantially opaque substrate 70. As illustrated, the reflector 80
is positioned therebetween the first and second substrates 70 and
100, respectively. As seen in the drawings, the second supporting
substrate has a first surface 101 which rests, at least in part, in
contact with the second surface 82 of the reflector 80, and a
second surface 102. Still further, a plurality of apertures 103, as
seen in FIG. 4, are formed in the second supporting substrate 100.
Matingly received within, and disposed in an occluding relation
relative to the apertures 103, are individual, second
electromagnetic radiation emitters 104, here illustrated as side
emitting, light emitting diodes. As depicted in FIG. 4, it should
be understood that each of the second plurality of electromagnetic
radiation emitters, here illustrated as side emitting, light
emitting diodes 104, include a heat sink 105. As should be
understood, during operation, and when energized, the second
plurality of electromagnetic radiation emitters 104 generate heat
energy. The arrangement, as shown in FIG. 4, allows the heat energy
generated by the second plurality of electromagnetic radiation
emitters 104 to be dissipated, at least in part, into the housing
40 and thereby prevent the undue buildup of heat energy in the
assembly 10 which may cause a failure of the assembly 10 and/or the
individual electromagnetic radiation emitters 104, as provided.
When energized, the second plurality of electromagnetic radiation
emitters 104 emits visibly discernable electromagnetic radiation
106 which is reflected by the second portion 84 of the reflector 80
along a course of travel to form the illumination zone 33 as seen
in FIG. 8C. A portion of this second course of travel is in a
different direction from that provided by the first electromagnetic
radiation emitters 75. As best understood by a study of FIGS. 1, 2,
and 4, the assembly 10 may include a third plurality of
electromagnetic radiation emitters which are generally indicated by
the numeral 110. This third plurality of electromagnetic radiation
emitters 110 are mounted on the second surface 72 of the first
substrate 70, and are electrically coupled to suitable electrical
pathways which are borne by the second surface of the first
substrate (not shown). As seen most clearly by reference to FIGS. 3
and 4, the third plurality of electromagnetic radiation emitters
110 are each individually associated with respective reflector
pockets 85 and which are formed and otherwise oriented in a fashion
so as to project the electromagnetic radiation 111 emitted by the
third plurality of electromagnetic radiation into the illumination
zone 32 as seen in FIG. 8B and in a third direction.
[0033] Referring now to FIG. 1 and following, it will be seen that
the assembly 10 includes a housing which is generally indicated by
the numeral 120. The housing is operable to receive, and partially
enclose, in a somewhat nested arrangement, the various assemblies,
discussed above. In this regard, the housing 120 includes a bottom
portion 121. The bottom portion 121 includes a plurality of
apertures 122, which are substantially coaxially aligned relative
to the heat sinks 105 of the respective second plurality of
electromagnetic radiation emitters 104. The apertures 122 further
facilitates the dissipation of the heat energy generated during the
energizing of the respective second electromagnetic radiation
emitters into the housing 40, and which is mounted on the overland
vehicle 11. Extending generally normally upwardly relative to the
bottom portion 121 is a substantially continuous sidewall 123. The
sidewall and bottom portion 121 define a cavity 124 which matingly
and nestingly receives and otherwise operably cooperates with the
assemblies described above. The housing 120 is itself, then
matingly or otherwise mounted, along with the semitransparent
mirror or substrate 50, to a mirror bezel (not shown) and which is
received within the housing 40. In this fashion, the assembly 10
can be oriented in a proper position so as to be useful to the
operator of an overland vehicle 11.
[0034] Referring now to FIG. 7, a second form of the invention is
generally indicated by the numeral 130. As shown therein, the
second form of the invention includes many features similar to that
of the first form of the invention 10. Like structures in many
instances have been shown and for those reasons bear similar
numbers. In this regard, the semitransparent mirror or substrate
50, second substrate 100, and housing 120 are substantially
identical to that described with respect to the first form of the
invention, and therefore further discussion with respect to those
structures is not warranted. The second form includes a first
substrate 131 which has a different shape from that seen with
respect to the first form as illustrated in FIG. 1. The first
substrate 131 has a first surface 132, and a second surface 133. As
seen, a first plurality of electromagnetic radiation emitters 134
are mounted on the second surface 133. Suitable electrical conduits
are borne by the second surface and are coupled to a source of
electricity which is typically supplied by the automotive platform
11. As should be understood by a study of FIG. 6, the first
substrate, and housing 120, in combination and in the assembled
form as seen in FIG. 6 defines discrete regions 135 through which
emitted electromagnetic radiation, as described below, passes. This
electromagnetic radiation is then passed by the semitransparent
mirror or substrate 50 such that it forms a discrete signal which
can be viewed at a distance from the assembly 130. As should be
understood, and when assembled, the first surface 132 would be
juxtaposed relative to the second surface 52 of the semitransparent
substrate 50, and in the region 61.
[0035] As seen in FIG. 7, the second form of the invention 130
includes a reflector 140 which has a first surface 141, and a
discrete, second surface 142. Still further, the reflector has a
first portion 143 and a second portion 144. As seen in FIG. 7, the
first portion 143 is defined by a plurality of individually
discrete reflector pockets 150 which are somewhat similar in their
overall function as that seen in the earlier form of the invention
10. In this regard, the plurality of reflector pockets 150 are
defined by individual reflector facets 151 (FIG. 6), and are
operable, as seen, to reflect the electromagnetic radiation 152 in
various directions. As seen in FIG. 6, some of the plurality of
reflector pockets 150 reflect the emitted electromagnetic radiation
152 in a first direction so as to be seen within the illumination
zone 31 as seen in FIG. 8A. Further, the second portion 144 of the
reflector 140 is defined, at least in part, by individual apertures
160 which are formed in the reflector 140. Still further, the
second portion 144 includes individual reflector facets 161 which
extend away from the first surface 141 and are positioned in
reflecting relation relative to the second electromagnetic
radiation emitters 104 and which are mounted on the second
substrate 100. When energized, the electromagnetic radiation of the
second plurality of electromagnetic radiation emitters 104 is
reflected in a second direction as indicated by the line labeled
162. This electromagnetic radiation is then provided to the
illumination zone 33 as seen in FIG. 8C.
[0036] In the second form of the invention 130, a third plurality
of electromagnetic radiation emitters 170 is provided and which are
mounted on the second surface 133 of the first substrate 131. When
energized, the third plurality of electromagnetic radiation
emitters are operable to provide electromagnetic radiation 171
which is reflected by individual reflector pockets 150 into the
illumination zone 32 as seen in FIG. 8B. As seen in FIG. 6, where
the second form of the invention 130 is shown in an assembled
configuration, this assembled configuration is then received or
otherwise mounted on a mirror bezel, (not shown), along with the
semitransparent mirror or substrate 50 and thereafter oriented in
an appropriate fashion so as to be useful to an operator of an
overland vehicle 11.
Operation
[0037] The operation of the described embodiment of the present
invention is believed to be readily apparent and is briefly
summarized at this point.
[0038] Referring now to FIG. 1 and following, an electromagnetic
radiation assembly 10 and 130 of the present invention includes a
reflector 10 and 140 which has first and second surfaces 81, 82,
141, 142, and first and second portions 83, 84, 143, 144. Further,
this assembly 10, 130 further includes a first electromagnetic
radiation emitter 75, 134 positioned adjacent to the first surface,
and which, when energized, emits visibly discernible
electromagnetic radiation 76, 152 which is reflected by the first
portion of the reflector so as to be visible at locations forward
of the first surface; and a second electromagnetic radiation
emitter 104, positioned adjacent to the second surface of the
reflector, and which, when energized, emits visibly discernible
electromagnetic radiation 162 which is reflected by the second
portion of the reflector so as to be visible at locations forward
of the first surface. The electromagnetic radiation assembly 10 of
the present invention further includes a semitransparent mirror or
substrate 50. The visibly discernable electromagnetic radiation
emitted by the first and second electromagnetic radiation emitters
75, 104, 134 passes through the semitransparent mirror and can be
seen at a distance, and in different directions, and typically
within the illumination zones 31, 32 and 33, respectively.
[0039] With regards to the electromagnetic radiation assembly 10,
the present invention includes a first substantially opaque
substrate 70 positioned therebetween the semitransparent mirror or
substrate 50 and the reflector 80. The first opaque substrate
defines a region 73 through which the visibly discernable
electromagnetic radiation may pass. With regard to the first and
second forms of the invention 10 and 130, the first electromagnetic
radiation emitter 75, 134 is mounted on the first opaque substrate
70, 131 and near the region which passes the visibly discernable
electromagnetic radiation. The electromagnetic radiation assembly
10 and 130 of the present invention further includes a second
substrate 100 which is positioned in spaced relation relative to
the second surface 82, 142 of the reflector 80, 140. In this
regard, the reflector is located therebetween the first substrate
70, 131 and the second substrate 100, and the second
electromagnetic radiation assembly 104 is mounted on the second
substrate 100. With regards to the first and second forms of the
invention, the first portion 83, 143 of the reflector 80, 140
comprises, at least in part, a reflector pocket 85, 150 having
multiple reflector facets. The respective reflective pockets each
define a cavity 86 which is typically positioned in eccentric,
reflecting relation relative to the first electromagnetic radiation
emitters 75, 134. The respective reflector pockets reflects the
emitted visibly discernable electromagnetic radiation emitted by
the first electromagnetic radiation emitter 75, 134 in a first
direction as illustrated in the drawings. In the arrangement as
seen, the second portion 84 of the reflector 80, 140 comprise, at
least in part, an aperture 91, 160 which allows the visibly
discernable electromagnetic radiation generated by the second
electromagnetic radiation emitter 104 to pass therethrough. The
second portion includes a reflector facet 92, 161 having a
reflecting surface which is located adjacent to the aperture and
which is further positioned in spaced relation relative to the
second surface 82, 142 of the reflector 80, 140, and in reflecting
relation relative to the second electromagnetic radiation emitter
104. Visibly discernable electromagnetic radiation emitted by the
second electromagnetic radiation emitter 104 is reflected by the
reflector facet of the second portion of the reflector in the
second direction. In the arrangement as seen, a third
electromagnetic radiation emitter 110, 170 is mounted on the second
surface 72, 133 of the first substrate 70, 100, and wherein the
electromagnetic radiation generated by the third electromagnetic
radiation emitter is reflected by one of the reflector facets in a
third direction. When assembled, and as seen in the drawings, the
emitted visibly discernable electromagnetic radiation is operable
to pass through the semitransparent substrate or mirror 50, and
pass into first, second and third illumination zones 31, 32, and
33, respectively so as to be useful to the operator of the overland
vehicle 11, or other vehicles traveling adjacent thereto.
[0040] Therefore, it will be seen that the electromagnetic
radiation assembly 10, 130 of the present invention provides many
advantages over the prior art devices which have been utilized
heretofore. As will be recognized, the present assembly 10 and 130
is compact, cost efficient, and further provides a convenient means
whereby discernable electromagnetic radiation may be projected in
various directions and patterns relative to the overland vehicle to
assist the operator in the use of the overland vehicle.
[0041] In compliance with the statute, the invention has been
described in language more or less specific as to structural and
methodical features. It is to be understood, however, that the
invention is not limited to the specific features shown and
described, since the means herein disclosed comprise preferred
forms of putting the invention into effect. The invention is,
therefore, claimed in any of its forms or modifications within the
proper scope of the appended claims appropriately interpreted in
accordance with the doctrine of equivalents.
