Description

Reflector for Illuminated advertisements and illuminations 1 The present Invention relates to reflectors cooperating wit'rr ^ l ight sources for decorative il lumination, luminous advertisement and other purposes .

It 1s an object of theppresent Invention to provide a reflector that gives the impression to the viewer that he sees mul tiple light sources ; the reflector 1s to be used as supporting and building block component for and 1n advertising signs having , e.g . larger letters , channel letters or the l ike.

In accordance with the preferred embodiment of the invention it is suggested to provide a reflector 1n form of plural , superimposed , truncated pyramids with a common axis and polygonal bases , and having larger apex angles for the respective truncated pyramids of smal ler base area. The outer periphery at the base of the largest pyramid is to have a mounting strip of flange extending transverse to the base area, I .e. , paral lel to a common axis of the pyramids . Preferably, two truncated pyramids are used , with a hexagon as polygon to define the base contour of each pyramid.

Whi le the specification concludes with claims particularly poi nting out and distinctly claiming the subject matter which 1s regarded as the Invention , 1 t 1s believed that the Invention , the objects and features of the Invention and further objects , features and advantages thereof wil l be better understood from the following description taken 1n connection with the accompanying drawings in which : Fig. 1 is a front view of a reflector, constructed 1n accordance wi th the preferred embodiment of the Invention ; F1g. 2 1s. a section view along line A-B of F1g. 1 and Fig. 3 Il lustrates a detail , 1n section view, of two combined reflectors with connecting parts .

Preceding now to the detai led description of the drawing , 1n F1g . 1 1s n iutrated a reflector 1 having base contour of a regular hexagon. The reflector Itself 1s constructed as two hol low superimposed 38037/2 by twel ve planar, Internal surfaces 2. These surfaces are mutually Incl ined to each other to establ ish two six-sided pyramids of different apex angles.

. The surfaces 2 themsel ves are the Individual reflector elements , for reflecting the filament of a light bulb; or 1n case the bulb has a frosted envelope, the luminous bulb Itself 1s reflected by each of these surfaces. Reflection may result by using deep drawn metal that Is polished and provides by Itself specular reflection. In case of plastic, the Inner surfaces should be metallized to obtain reflective surfaces.

The light bulb (not shown) Is arranged In the Interior of the reflector construction and on the central and common axis of the double-truncated pyramid; The buftfi may be of the two-color variety 1n that Its surface below the portion of largest diameter has one color, the remainder of the bul b having the other color. In order to receive the bulb socket, a central opening 3 Is provided In the refft&ctor, receiving the electrical connecting components and socket etc. of the bul b.

The reflector Is to be used as self-supporting component and carrier. Therefor, a mounting flange 4 1s provided, transverse to the base area of the reflector and extending from the periphery of largest diameter, 1n hexagon contour, around the axis of the reflector unit; the flange runs paral lel to the pyramid axis . Plural such reflectors can be combined by connection of the respective mounting flanges 4 to establish large Il luminating units such as letters , luminous areas , pictures , etc.

Each mounting flange 4 has on Its Inside at least one pocket 5 (pl ural pockets are shown In , ) the drawing) . The pocket extends transverse to the hexagon contour area base of the reflector and has rectangular cross section (1n the plane of pyramid base) . A central - y, symmetrical ly running slot 6 1s provided for access from the outside to pocket 5 and running parallel to the axis of the reflector (see Fig. t2) . The slot 6 serves for receiving a connector element 7, having H-shaped 6 of two juxtaposed reflectors . This way, juxtaposed reflectors are positively Interconnected.

In cases 1t may be advisable to combine plural reflectors 1n Integral construction to obtain subgrouplngs of plural reflectors as basic units or bui lding blocks , reduci ng the amount of mounting work and handling needed at the instal lation site. As an example, one can think of barl ike assembl ies to be used as basic l ines 1n the assembly of letters.

The Invention has the advantage that very effective Illuminating advertisement displays can be assembled at low cost with Uttle expenditure and by means of basical ly simple construction. Also, the assembly may easi ly be taken apart. This 1s of particular alvantage as decorations, window displays , etc. , are frequently changed. The Individual reflectors or subgrouplngs thereof may be made of plastic. As they are self-supporting and stabll 1n themselves ; even large configurations can be assembled without requiring additional support and carrier structure. The connecting element 7, as described , permits also quite rapid assembly and combining of many reflectors. Also, the reflectors can subsequently be equipped electrical ly subsequently, and bulbs can be Inserted quite simply as each reflection 1s also the carrier of a lamp and bulb holder.

■ The Invention Is not l imited to the embodiments described above but all changes and mb^i cations thereof not constituting departures from the spirit and scope of the Invention are Intended to be Included.
