United States Patent O] 3,4 l 9 ,986 Patented Jan. 7, 1969 4 Claims ABSTRACT OF THE DISCLOSURE An illuminated and illuminatng sign has a translucent reflector that houses the source of illumination in the centrally located dished out face portion thereof. The reflector has outwardly diverging translucent sides with a translucent and inwardly refiecting sign face positioned opposite the source and spaced outwardly of the end extremities of the diverging sides. The light source cooperates with the subject Construction in that it has a wafered ;face plate. Each bubble thereon acts as an individual light source thereby aiding in ditfusing and spreading the light rays over the entire face and through the translucent reflector. The translucent reflector may be colored, thereby producing colored light rays which are substantially the same color as the reflector in order to accentuate ;significant colors and objects for advertising and display purposes.

This invention is an improvement over my Patent No. 3,076,277, issued Feb. 5, 1963, entitled, "Illuminated Sign.

One object of the invention is to provide a uniquely illu-minated and illuminating sign that makes maximum functional and aesthetic use of all light emanating from 'the source employed. This complete utilization of avail- .able light results in significant saving in lighting costs, 'both from the standpoint of the type and quantity of 'illumination sources required, as well as the watt-hour `power Consumption of a single source.

Another object of the invention is to provide an illumi- 'nated sign structure wherein the halo elfect disclosed 'in my previous patent, supra, is enhanced and improved .and wherein efl icient, eflective usefulness and versatility are maximized.

Another object of the invention is to provide an illumirated and illuminatng sign having at least two opposed 'face panels, each capable of carrying advertising copy, .each illuminated and illuminatng in unique manner from 'a single light producng source and wherein at least one of the principal faces has a markedly greater display area than the adjacent area of the light source.

A further object of the invention is to provide an illuminated and illuminatng sign of the character described 'which is uniquely adapted as to light other nearby objects and surfaces while simultaneously effectively lighting and displayng the sign.

A still further object of the invention is to provide a sign const'uction that produces a controlled, diifused night light while simultaneously illuminatng at least one face panel.

Another object of the invention is to provide for an .illuminatng `and illuminated sign, an improved reflector structure, manufactured of translucent :material such as plastic, said reflector having aiiixed thereto improved rneans for mounting a large translucent light transmitting .and reflecting face panel at an extended distance there- 'f'om, said mounting means permitting easy insertion and removal of said panel therein.

A further object of the invention is to provide an improved illuminated and illuminatng sign including a re- 'flector and a display panel wherein either or both the face panel and reflector may be const ructed of translucent plastic of varied color. This feature enables sign light fluxes emanating through the various colors to be used `to accentuate distinctive product colors in and around advertising displays and to illuminate ceilings or walls with pleasing light tones while simultaneously providing illuminated copy or indicia `on more than one sign display face.

A still further object of -my invention is to provide a unique method of and structure for simultaneously illuminating advertising sign display surfaces and at least a 'portion of a room, wherein said sign may be located, all from a single light source within the sign structure.

Other and further objects of the invention will appear in the course of the following description thereof.

In the drawings, which form a part of the instant specification and are to be read in conjunction therewith, em- 'bodiments of the invention are shown and, in the various views, like numerals are employed to indicate like parts.

Refe'ring to the drawings, the reflector generally indicated by the numeral 10 is preferably substantially or entirely composed of a translucent material such as Plexglas or other suitable plastic. All surfaces of reflector 10 are, to a substantial degree, smooth and polished and thereby have high reflectivity characteristics. Reflector 10 has a central dished portion lila which forms the squared rear panel of the reflector. Perpendicular sides 1017 extend outwardly from rear face 10a, forming a preferably square-shaped mounting recess of a depth appropriate to accommodate a similarly shaped light source to be later described. Angled sides 10d diverge from a lip 100, which circumscribes perpendicular sides 10b, and terminate in a similar shaped 'but larger square circumscribing lip 10e. Angled sides 10d -form an open-ended, frusto-conical, outwardly diverging reflector ring adjacent the face of the light source when said source is appropriately mounted. The internal surfaces of sides 10d are reflective, -as noted.

The mounting recess, defined by reflector sides 10b, is particularly sized to receive a light source of panel fluorescent lamp type as seen at 11 in FIG. 4. The panel fluorescent lamp manufactured by the General Electric Company, identified by their code PF-12S lamp, works quite satisfactorily as the source of illumination. The particular named lamp, which is capable of producng approximately 4300 lumens, employs a corrugated or wafered face plate 11a with a glass envelope 11b arranged in a serpentine fashion 'and formed integrally with the face plate. During normal operation, approximately 2500 lumens typically emanate through the face plate while the back of the light source gives off less than half of the source's total capacity or approxirnately 1800 lumens. Face plate lla is slightly larger than the squared mounting recess and therefore circumferentially bears against and abuts the frontal exterior of lip 10::. A single clear acrylic plastic strip 12, held in place by bolted angle bracket 13, runs the length of the lower edge of face plate 11a while similar -bracket 13a contacts the upper edge of face plate 1111, thereby securely locating panel lamp 11 within the mounting recess.

I have shown two different mounting embodiments for positioning the enlarged, square, translucent sign face panel 14 adjacent the refiector sides 10d, but spaced away therefrom and from the source of illumination. In regard to the shape of panel 14, it is only necessary that the panel be similar in frontal shape with that of the light source for purposes of uniform light distribution.

Referring now to FIGS. l-S, inclusive, the sign face panel 14 is held away from refiector 10 and the entire sign is mounted in sturdy aluminurn framework. As a part of this framework, structurals 15 and 16 are designed to fit and engage the inner sides of lips 100 and 10e with structural 16 bolted to lip 10e (see bolts 16a). These square-shaped structurals are then connected by diverging aluminum angles 17 which terminate in a square faced panel receiving channel generally indcated at numeral 18. As shown in FIG. 5, a set of screws 18a extend through the outer angle 1817 and the inner angle 130 of channel 18, thusly locating sign panel 14 therewithin.

Ballast 19, with wiring 20 for fluorescent panel light 11, is preferably mounted so that it st'addles the aluminum structurals 15 and 16. However, the ballast may be remotely located from the sign structure itself, with only wiring 20 leading to the fiuorescent panel light. Alternately, and in some cases preferably for support and reflection purposes, ballast 19 will be positoned on top of, rather than under a vertically mounted refiector as shown in FIGS. 2, 3 and 4.

As seen in FIG. 3, the illuminated sign is supported by link chain 21 in a position adjacent a vertical wall surface. The link chain 21 is of the type that could hang from a conventional wall hook eye and in such instance, clear acrylio plastic stub legs (not shown) of a preselected length with rubber pads will be added to connect with structural 15, thereby supporting the illuminated sign a preselected distance from the wall. This preselected distance facilitates in the night lighting effect described later.

FIGS. 6-9 represent a different face panel mounting means and depict therein a panel face holding channel 22 and connectors 23, which are constncted of clear acrylic plastic. Channel 22 is open along one edge allowing for quick removal and replacement of face panels. The projected face panel 14 mounted in its associated holding channel 22, is held away from the translucent reflector 10 by the clear acrylic plastic connectors 23. Connectors 23 are fastened to the reector's diverging corners by aluminum pop rivets 24, best seen in FIG. 9, and are braised to the corners of holding channel 22.

Because channel 22 and connectors 23 are made from transparent plastic rather than aluminum, it is lighter in weight and presents less light blockage and fewer Shadows. As a result, this sign Construction is easily portable and is sometimes set or leaned against counter or display shelves.

Another typical support for this type of illuminated sign is shown in FIG. 6 wherein the sign structure is rigidly supported from a joist or ceiling area with the accompanying ballast 19 located interiorly of the ceiling. When utilizing the rigid support mentioned above, an aluminum square frame 25 will be bolted to lip 100 at selective intervals. A pair of aluminum bar extensions 26 are welded at intervals on two sides of frame 25 and are internally threaded to connect with threaded rods 27. Rod 27 'may then extend through drilled holes in ceiling 28 and threadably engage supporting plates 29 which may be nailed or otherwise connected to joist 30. The abovementioned threaded rod connection allows the distance 'between rear panel 1011 and ceiling 28 to be selectively varied by adjustment of the externally threaded rod 27.

In my Patent 3,076,277, supra, the light source, an opaque refiector, and a translucent sign face panel were arranged in a particular fashion to produce a halo or light circle efiect on the wall or 'hacking surface surrounding the general area of the sign. By varying the position of the reflecting surface rearwardly of the sign face, the halo position and form could be varied so long as there Was a separation between the refiector and the rear of the sign face panel. This separation allowed the reflected and ditfused light rays bouncing off the interior of the sign face panel, for example, to pass therethrough unobstructed after their initial reflection and to finally reflect against the wall or hacking surface.

The instant sign construction likewise produces the halo effect behind sign face panel 14, however the usable percentage of available light emanating from the light source is signicantly increased by use of the translucent refiector 10. Direct rays from source 11 will be projected through rear panel 10a even though panel 10:: is translucent, rather than transparent. Additional light emission and glow effect is had around the translucent diverging angled sides 10d. Thus direct, reflected, diffused and intercepted light rays are played against wall surfaces and other objects surrounding the rear and adjacent area of the sign.

As earlier noted, the face panel 14 and the light source should be approximately the same shape. I have found that by using a square light source such as source 11, the entire square face panel 14 is uniformly lighted with no dead Spots located therein. Accordingly, with the instant Construction, a substantially smaller light source will illuminate a much larger sign area, as well as optimalzing the use of the 1800 lumens given off from the back side of the light source.

A typical example of the increased usable light is seen with reference to FIG. 3. Here the instant sign construction is shown, chain dropped a preselected distance away from the back wall of a room or store window. If, for example, the back wall is opposite the store window in the front of a "building, the illuminated sign could 'be used both to display and convey an illuminated message on the sign face panel accompanied by the halo effect, while at the same time, transrnitting suicient direct and reflected light rays through rear face 10:: of the refiector to light either the entire or a significant portion of the back wall area. Thus the illuminated sign is serving in dual capacities as both a night light and as a source of advertising illumination for the message carried on the front sign face panel.

The embodiment disclosed with reference to FIG. 6 has a similarly constructed refiector ring and light source. This mounting arrangement maintains the above-mentioned dual purpose capability of illuminating the sign panel face 14, while directly lighting the ceiling 28. In this instance, it is also conternplated that the rigid mount represented 'by threaded rods 27 may be replaced by link chains of the type that will allow the sign structure to be more easily raised or lowered to suit the need of projecting direct, diffused and reflected light as the circumstances may dictate. This embodiment allows illuminated signs to actually serve as the entire illuminating source for a store, office or waiting room area. The advertising indicia or copy (not shown) may still be dislayed on frontal panel 14 while selectively spaced sign structures ranging from the ceiling will adequately illuminate the store, office or shop with a pleasant indirect light. This eifect is created by the direct transmission of forward light through face panel 14 as well as the reected and diffused light rays emanating from in and around the rearwardly refiecting face panel, the translucent reflector sides and rear panel, and the various light refiecting surfaces therearound such as the ceilings and walls. This type of light, the direct, diifused and reflected rays, has a tendency to "hug the walls and ceiling and eifectively eliminates Shadows around counters, desks and working areas below.

The unique sign Construction greatly facilitates the advertising potential of illuminated signs. By selecting colored translucent refiectors, various promnent and identifiable trademark colors and features may be accentuated in window displays or at significant display and purchase points in retail stores. For example, the instant sign Construction may be used to display advertising copy on its frontal face panel while it is chain mounted in a display window. The direct rays emanating from the light source through a color translucent reflector may highlight some significant color or object on display in the window. t

When desired, the various embodiments may be mounted away from a wall and advertising indicia or copy (not shown) may be placed directly on the rear panel 1012, for an interior message, as well as the larger message on the frontal face panel 14. The sign may be revolving, stationary, mounted on a parapet or marquee or include color translucent reflectors of the type mentioned above. In this instance, transmitted, direct, diffused and 'eflected light rays, along with the above-mentioned halo effect results in a great deal of versatility from an advertising, illuminating and displaying standpoint.

The various sign Construction mentioned above also may be utilzed for its potential room illumination ability. In this instance the distance that the sign itself is positioned away from a wall surface or ceiling surface plays a significant role in the type of illumination atforded. If, for example, the above-mentioned fiuorescent panel light were used as the light source in the FIG. 3 embodiment, it is estimated that the rear face lOa should be located some 5 to 6 inches away from the wall surface. This distance allows the direct, transmitted, dilfused and reflected light from a single sign to sufficiently light the entire back wall of a moderately sized room. Similarly an illuminated and illuminating sign of this Construction can light an area in front of a display window as well as the display window area and the room area behind it.

From the foregoing, it will be seen that this invention is one well adapted to attain all of the ends and objects hereinabove set forth, together with other advantages which are obvious and which are inherent to the structure.

It will be understood, that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the clams.
