[0001] This invention relates to advertising displays and, more particularly, to an illuminated
display that can be constructed a) with a fixed size and shape and b) from a plurality
of modules that can be selectively joined to produce a size and shape as desired by
the end user.
[0002] For over half a century, neon signs have been extensively used in advertising, particularly
on store fronts and the like. Neon signs are desired for their intensity and their
three dimensional look. Bright colors can be observed over a wide viewing angle.
[0003] Neon signs, however, have numerous drawbacks. First of all, the signs are constructed
by bending glass tubing. Intricate bending steps are often required to produce a desired
message. As a result, relatively highly skilled labor is required to manufacture such
signs. Some shapes may be so demanding that cost becomes prohibitive.
[0004] Some shapes cannot be reproduced at all with neon, regardless of the skill of the
fabricator. As a result, certain shapes, such as those used in well known logos, and
the like, must be modified. For example, if there are width variations in lettering,
this may not always be possible to reproduce in neon. This precludes uniformity in
advertising and may detract appreciably from the look of a sign.
[0005] A further drawback with conventional neon signs is that each colored tube must be
constructed with its own circuit. This often results in a maze of tubing which is
unsightly when viewed at close range.
[0006] A further drawback with conventional neon tubes is that they are prone to breakage.
The glass tubing must be sufficiently thin to facilitate its bending. Further, the
tubes, upon being bent, may be stretched so as to become thinner and even more brittle.
Accidental bumping of the tubes could cause rupture thereof that releases the confined
gas and requires reconstruction of an entire circuit. Breakage is quite common during
shipping and handling of signs with neon. In fact, some studies have shown that as
much as 10% of shipped neon tubes sustain some damage.
[0007] A further drawback with neon signs is that they require transformers which are not
only unsightly but prone to failure. It is very common to see certain circuits of
neon signs flickering, which detracts from the appearance of the sign. It is also
common for a failing transformer to produce an annoying humming noise which may be
audible from a substantial distance away from the sign.
[0008] A further problem with neon signs is that they are normally custom made with there
being no flexibility afforded the end user. If the end user desires to change a sign,
as to increase size, an entirely new sign must be purchased.
[0009] Still further, neon does not lend itself to signage using back lighting. Conventional
signs are normally either dedicated neon or back lighting signs.
[0010] The use of neon signs may also be limited by local safety regulations. Neon signs,
to date, cannot be manufactured to meet U.L. specifications.
[0011] While the above problems have plagued the advertising industry for years, designers
have contended with these problems for want of an alternative that produces a colorful,
intense, three dimensional message comparable to the neon sign.
[0012] The present invention seeks to overcome the above problems in a novel and simple
manner.
[0013] More particularly, the present invention is directed to a sign that uses illumination
to enhance a message on the sign that is displayed. A housing for carrying the message
is used together with a reflector having a light reflective surface. The reflector
is mounted to the housing so that light from a source projected at the reflector is
directed towards the message. The reflective surface has at least a portion with a
parabolic cross-sectional configuration to focus a substantial amount of light from
a source on the message to be displayed.
[0014] By connecting a light source to one of the reflector and housing in the vicinity
of the focal point for the parabolically-shaped reflective surface, the width and
intensity of the light from the source is increased. In essence, the parabolically-shaped
reflective surface serves to enlarge the size of the light source.
[0015] The light source is, in one form, a fluorescent bulb and preferably at least a 20
watt fluorescent bulb to generate the desired intensity of light.
[0016] The light source is preferably tubular in configuration and has at least a portion
that is non-straight. The parabolic portion of the reflective surface is preferably
conforming in shape to the tubular light source. In one form, the light source is
a bulb that defines a closed loop with the reflective surface having a matching configuration.
[0017] In one form, the reflector is made from molded plastic and has a light reflective
coating defining the reflective surface. The coating may be applied by a vacuum coating
process.
[0018] With the inventive structure, a relatively inexpensive sign can be constructed that
is very visually appealing. The fluorescent tubes are relatively durable, as is the
reflector, particularly when it is made of plastic. Thus, the possibility of breakage,
during shipping, is substantially reduced over neon signs.
[0019] In one form, the message is defined on the sign by at least one panel with lenticular
structure which produces a raised, illuminated message that is visible from the front
of the device. By projecting the high intensity light through the lenticular structure,
the light is redirected and effectively magnified to produce the appearance of neon
without the disadvantages associated therewith.
[0020] At the same time, the high intensity forwardly projecting light produced through
the inventive reflector virtually eliminates voids and makes the reflector of the
present invention highly desirable to produce back lighting for more conventional
type displays. Thus it is possible to integrate conventional back-lit messages with
neon-simulating structure, according to the invention, into one sign. The illumination
is sufficiently intense that the sign is useable with a darkened background, as on
walls and ceilings, as well as in windows where there is no contrasting background,
as is a common location for neon signs.
[0021] Truer graphic representations of existing logos can be achieved with the inventive
structure. Width variations on lettering, sharp corners, etc. can be reproduced with
the lenticular structure, as by molding the same to virtually any shape. Screened
or litho graphics, heretofore too complicated and costly to produce in neon, can easily
be incorporated into the inventive sign.
[0022] To further enhance the brightness of the light reflected by the parabolic surface,
a raised rib can be provided, preferably centrally of the parabolic surface. That
light, which would otherwise be reflected in such a manner that it would be blocked
by the light source, is redirected against the parabolic surface at a location spaced
from the rib to be directed at a message to be displayed.
[0023] To add flexibility to the sign, the invention further contemplates that the sign
may be made in modular form. In one form, at least one of the housing and reflector
is constructed to be connected to a sign of similar construction to increase the message
display area.
[0024] To effect this interconnection, at least one of the housing and reflector on each
of the first and second of the signs has cooperating clips which, in one form, are
in the shape of dovetail connectors. By aligning the first and second signs in a preassembly
position and relatively moving the first and second signs against each other, the
clips are interconnected. The signs can be disassembled to reconfigure the overall
appearance of the sign.
[0025] The individual modules are normally polygonally-shaped and can be square, rectangular,
diamond-shaped, etc.
[0026] Virtually a limitless combination of sign sizes and shapes can be made with the basic
modules. The ability to customize signs is a tremendous asset to franchisors and distributors.
A basic unit can be made common to all franchisees/distributors with a portion of
the sign customized to the individual entity and/or geographical location. The signs
can also be changed periodically as demand dictates. At the same time, the module
can be constructed so that the frame is unobtrusive and does not detract from the
custom look of each sign.
[0027] Further enhancements to the sign are also contemplated by the invention. For example,
animation can be incorporated into one or more of the modules.
[0028] Additionally, assembly and replacement of the light source can be accommodated by
molding a receptacle into the reflector that receives and maintains the light source
consistently in an operative relationship with the reflector. Typically, the light
has a housing which is fitted in the reflector receptacle. A reflective tape can be
provided on the housing to avoid any diminishing of light projection by reason of
non-reflection by the housing.
[0029] The invention further contemplates a reflector for use in a sign to reflect light
from a source so as to enhance a message on a sign, wherein the reflector has a reflective
surface with at least a portion that has a parabolic configuration to focus light
from a source in a direction to enhance the appearance of a message on a sign.
[0030] For a better understanding of the present invention and to show more clearly how
it may be carried into effect, reference will now be made, by way of example, to the

[0031] In Figs. 1-3, a preferred form of illuminated sign, according to the present invention,
is shown at 10. The sign 10 has a message 12 viewable from the front thereof. The
message 12 in Figs. 1 and 2 is shown strictly for purposes of illustration, as normally
the message on the signs 10 will be custom made for each consumer.
[0032] The sign 10 consists of a rectangular housing 14 having a rear wall 16 and an integral,
forwardly projecting peripheral wall 18. The walls 16, 18 cooperatively define a forwardly
opening component receptacle/space 20 for, in this case, three conventional fluorescent
tubes 22, 24, 26 which make up the light source for the sign 10.
[0033] At the open forward edge 28 of the housing 14, a message carrying wall at 30 is provided.
The message carrying wall 30 is made up of a front panel 32 and a rear panel 34, each
having substantially the same rectangular shape to fit closely within a conforming
opening 36 at the front of the housing 14.
[0034] The rear panel 34 is preferably molded in one piece and includes a body 38 and raised,
lenticular letters 40 projecting forwardly from a generally planar surface 42 on the
body 38. The entire panel 34 is preferably molded from a clear material, such as acrylic
or polycarbonate. The letters may be polished for clarity, however, with known molding
techniques, this is generally unnecessary.
[0035] The raised letters 40 act to magnify light from the bulbs 22, 24, 26 and to effect
dispersion thereof. With the panel 34 in the operative position of Figs. 1 and 3,
the raised, lenticular letters 40 give the appearance of a three dimensional light
source at the front of the housing 14, to give the impression of neon. That is, the
letters 40 give the appearance that the source is within the letters 40 and projects
radially outwardly therefrom through approximately 270°.
[0036] A preferred form for the letters 40 is shown in Fig. 6. In cross section, each letter
40 is shown to be defined by an outer surface 44 that is generally a solid U-shape,
opening rearwardly. The outer surface 44 consists of a forward, convex surface segment
46 defined by a diameter D1 which blends into spaced, parallel, straight segments
48, 50, which are tangential to the surface segment 46.
[0037] In a preferred form, the diameter D1 is approximately 3/8" (9.5 mm) and the distance
D2 between the apex 52 of the surface segment 46 and the forwardmost surface 54 on
the message carrying wall 30 is approximately 3/8" (9.5 mm)
[0038] Returning to Figs. 1-3, in conjunction with Fig. 6, the rear surface 56 of the panel
34 is seen to be tinted where it coincides with the letters 40. The particular color
used is a design consideration. The color can be applied by techniques well known
to those skilled in the sign art. Light from the bulbs 22, 24, 26 will cause the forward
projection of the selected color light through the front of the sign 10.
[0039] The remaining portion of the panel 34 is made opaque by applying a coating on the
rear surface 56 thereof. The coating is preferably a white latex painted on the surface
that will reflect light, for reasons discussed below. The coating need not actually
be white, as other light reflective colors and treatments would give the same desired
result.
[0040] The front panel 32 serves as an opaque mask for the front of the sign 10 and normally
has a contrasting color to that of the letters 40 to highlight the letters 40. The
panel 32 has cut-outs 58 therein for close reception of the raised letters 40. The
cut-outs 58 may be preformed, die cut, laser cut, or otherwise formed by methods known
to those skilled in the art. The panel 32 may be black or smoke colored material,
brushed aluminum, or the like, that is capable of preventing light transmission therethrough.
[0041] The panel 32 has a flat rear surface 60 which facially abuts the planar surface 42
on the panel 34 with the panels 32, 34 operatively engaged as a subassembly which
is snap-fit to the housing 14 as by conventional clips 62 in cooperating receptive
openings 64 in the housing 14.
[0042] Light from the bulbs 22, 24, 26 projects through the translucent portion of the panel
34 to illuminate the letters 40. To enhance the amount of light transmission through
the letters 40, reflectors 66, 68, 70, for cooperation with the bulbs 22, 24, 26,
respectively, are provided. The reflectors 66, 68, 70 could be formed as a unit or
by joining separate pieces. Exemplary reflector 66 is described in relationship to
its cooperating bulb 22.
[0043] The reflector 66 defines a forwardly opening, U-shaped reflecting surface 72 which
disperses light projected rearwardly from the bulb 22 forwardly through the translucent
portions of the panel 34. This enhances the intensity of the light transmission at
the front of the sign 10 and tends to eliminate light voids. The coating, which is
preferably a white painted layer, on the rear surface 56 of the panel 34, intercepts
light rays that do not pass through the letters 40 and directs these rays back to
the reflector 66 to be dispersed in a forward direction.
[0044] A slightly modified form of sign, according to the present invention, is shown at
74 in Figs. 4-6. The sign 74 has a housing 76 defined by a rear panel 78, top and
bottom panels 80, 82, respectively, and end panels 84, 86. The panels 78-86 cooperatively
define a component space for the message carrying wall 30 and a two bulb light source
at 88. The primary difference between the sign 74 and that 10 in Figs. 1-3, is in
the arrangement of reflectors.
[0045] More specifically, the sign 74 has upper and lower inclined reflectors 90, 92 and
angled end reflectors 94, 96. The reflectors 90, 92 each make an angle ϑ with the
plane of the forwardmost surface 54 of the message carrying wall 30. The angle ϑ,
in a preferred form, is approximately 50°. The end deflectors 94, 96 are also preferably
inclined at a similar angle with respect to the surface 54. The reflectors are provided
on the sign 74 primarily to intensify forward light projection and eliminate voids.
The reflecting surfaces may be, for example, mirrored acrylic or polished metal.
[0046] Another form of the invention is shown in Figs. 7-15. In those figures, individual
sign modules 210 are shown to allow the end user to custom build signage.
[0047] More particularly, each module 210 is constructed in a square shape. The shape of
the module 210 is primarily a design consideration. The invention contemplates various
different shapes, but preferably those that are polygonal.
[0048] Each module 210 consists of a housing 212 having an outer frame 214 that determines
the shape of the module 210. Each module 210 has its own illumination means at 216
to project light through cooperating front and rear panels 218, 220, which define
a message at 222 that is visible from the front 224 of the module 210.
[0049] The frame 214 has two oppositely facing wall pairs 226, 228 and 230, 232 which are
joined to define an enclosed square space for the message-carrying panels 218, 220,
as well as a space for the illumination means 216.
[0050] Clip means are provided on the peripheral wall 234 of the housing 212 in the form
of female, dovetail connectors 236 and cooperating male dovetail connectors 238. The
connectors 236, 238 are provided in pairs on each wall 226, 228, 230, 232. The connectors
236, 238 are located so that with the module 210 aligned with a like module 210, male
connectors 238 are aligned with female connectors 236. The male connectors 238 are
aligned at the front of the female connectors 236 in a preassembly position. By then
pressing the module 210 with the male connectors 238 rearwardly, the male connectors
238 seat in the female connectors 236 and maintain the housings 212 on the two modules
210 in closely abutting, assembled relationship. Modules can be aligned and connected
on the other walls 228, 230, 232 in like fashion.
[0051] In Fig. 8, nine individual modules 210 are shown connected to define a large square
sign at 240. The shape of the sign produced from the modules 210 is merely a design
choice, as is the orientation of the modules 210. For example, the module 210 could
be rotated 90° so that they are displayed in a diamond shape.
[0052] The frame 214 can be made to have a minimal thickness so that the frame 214 does
not significantly interrupt the message displayed by the combined modules 210. At
the same time, since each module 210 is self contained, different types of panels
218, 220 can be employed on each housing 212 to produce a variety of different effects.
For example, the sign 240 can be made up of modules 210, some of which use the illumination
means 216 for back lighting, while others use the modules 210 to project light through
panels 218, 220 to produce the neon-simulating illumination as previously described.
[0053] While there are many advantages to the modular construction, one desirable feature
is that each sign 240 can be made generic by the manufacturer and customized by placing
a message in one or more of the modules 210 that is appropriate to a particular entity.
For example, a brewing company might have a basic design that is generic to all its
distributors. The individual distributors can then customize the sign to put their
own identity or identify geographical information or other information that is appropriate
to the end user's place of display.
[0054] The invention also contemplates a highly effective illumination means 216 to produce
an intense light with virtually no dead spots and which is useable for back lighting
and neon simulation alike. More particularly, a reflector 242 is made, preferably
as one piece in a molding process. The reflector 242 has a body 244 with a peripheral
flange 246 which diverges slightly from front to rear to allow it to be pressed into
and frictionally held within the back portion 248 of the frame 214.
[0055] With the reflector 242 and frame 214 in operative relationship, a light reflective
surface 250 on the reflector 242 is situated to direct light from a source 252 forwardly
against the message carrying panels 218, 220. The light reflective surface 250 is
preferably defined by a silver coating that can be applied to the body 244 under vacuum
by a process well known to those skilled in the art.
[0056] The body 244 is shaped so that the light reflective surface 250 has a parabolic shape.
By situating the light source 252 so that light therefrom emanates at or adjacent
to the focal point for the parabolic surface 250, a majority of the light from the
source 252 is projected forwardly at the message carrying panels 218, 220. In this
case, the light source 252 is a fluorescent bulb having a tubular body 254 shaped
to define a closed loop 256. The parabolic reflecting surface 250 is shaped to match
the configuration of the bulb body 254. What this arrangement does is cause effective
widening of the light source 252 to provide a uniform distribution of high intensity
light without voids as might produce darkened zones on the panels 218, 220.
[0057] It is preferred that the light source 252 be a high intensity light, and preferably
one that is rated at at least 20 watts. The bulb shown is one currently being made
by the General Electric Company and sold as its model 2700K. This is a 28 watt 2050
lumens bulb. Other shapes could of course be used, including a straight shape, while
still exploiting the focal advantage of the parabolic reflecting surface.
[0058] The light source 252 has a housing 258 which is used to receive power from a supply.
The housing 258 is also used according to the invention to support the light source
252 on the reflector 242. More particularly, a receptacle 260 is formed directly in
the reflector body 244 and allows the housing 258 to nest therein. With the housing
258 in the receptacle 260, the light source 252 is optimaily positioned with the body
254 thereon at the focal point of the parabolic reflecting surface 250.
[0059] A rear housing 262 contains a transformer 264 which is connected from a conventional
power supply through a cord 266. Power from the transformer 264 is supplied to a connector
268 that is joinable to the light source 252 through a press fit connection. To assemble
the power source 252, the user need only press the housing 258 into the receptacle
260. In addition to simplifying establishment of the electrical connection, the receptacle
260 consistently maintains the housing 258 in a position to optimally place the light
source body 254 at the focal point for the reflecting surface 250.
[0060] To avoid a dead spot due to the housing 258, a tape 270 with a light reflective surface
can be placed on the exposed surface of the housing 258.
[0061] To further maximize forward light projection, a central rib 272 is defined in the
body 244 through approximately the central axis of the parabola defined by the reflective
surface 250. Since the light source 252 is located at the center of the parabola defined
by the reflective surface 250, the light source 252 would block the forward direction
of light from the base of the parabola. The rib 272 is V-shaped so as to deflect light
from the light source 252 away from the light source 252 to another area of the reflecting
surface 250 to where it is projected forwardly without interruption by the light source
252.
[0062] To assemble the module 210, the components are successively assembled from front
to rear through the rear of the housing 212. The front and rear panels 218, 220 are
assembled so that the front surface 274 of the front panel 218 abuts to an inturned
flange 276 on the frame 214. The front panel 218 has individual letters 278, or other
design, die cut therein. The rear panel 220 has molded, lenticular projections 280
which fit within the cutouts 278 in the front panel 218. The front panels 218, 220
are made and function as described in detail previously herein.
[0063] Spacer clips 282 are mounted to the frame 214. The clips 282 have a forward edge
284 to abut to the flange 276 and a cantilevered finger 286 to captively hold the
panels 218, 220 against each other and in an operative position within the frame 214.
The clips 282 are preferably glued in place on the frame 214.
[0064] The back edge 288 of the clip 282 serves as an abutment to arrest forward movement
of the reflector 242. Thus a consistent spacing between the reflecting surface 250
and panels 218, 220 is established.
[0065] The rear housing 262 is connected to the reflector 242, as by screws or an adhesive,
so that the rear housing 262 and reflector 242 define a subassembly that slides into
and out of the back portion 248 of the frame 214.
[0066] A high intensity illumination means thus results with virtually no dead spots within
the module 210. The stacking of the individual modules 210 can be readily accomplished
by a press fit operation performed by the end user. The modules 210 can be disassembled
and reassembled in any desired configuration. The end user can readily access the
light source 252 to effect changing thereof by merely pulling out the subassembly
consisting of the reflector 242 and rear housing 262 and thereafter pulling out a
spent light source 252 and simply press fitting in a replacement light source 252.
[0067] It can be seen that the inventive sign is easy and relatively inexpensive to construct,
and durable and convenient to maintain. Virtually the only regular maintenance required
is the periodic replacement of bulbs. The signs can be constructed according to the
invention in virtually any size and shape.
