     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings, FIGS. 1 and 2 illustrate a decorative lighting assembly 10 embodying the present invention. The lighting assembly 10 comprises a frame 11 having a translucent front panel 12, side walls 14, 15, 16 and 17, and top and bottom walls 18 and 19, respectively. Preferably, the front panel 12 has a mottled or irregularly faceted outer surface to disperse light. Preferably, the front panel 12 is molded of plastic material integral with the other panels 14-19 to provide an enclosure. A rear panel 20 is mounted across the back of the frame and is preferably perforated to afford cooling of the lamp assembly. The side, top and bottom walls preferably have a regularly-faceted or diamond-like outer surface to disperse light emmanating from the interior of the enclosure. 
     As best seen in FIG. 2, a plurality of tubular lamp reflectors, such as the reflectors 22-40 are mounted in the frame 11. In the present instance, the reflectors 22-40 are molded together of a translucent opaque plastic to form a rigid unitary honeycomb-like structure which fits within the walls 14-19 of the frame 11 in the manner illustrated. The reflectors may be regarded as being grouped in rings concentric with the central reflector 22, the inner ring comprising the reflectors 23-28, and the outer ring comprising the reflectors 29-40. Although the reflectors 22-40 are disposed in a hexagonal pattern in the illustrated embodiment, other patterns can be utilized, depending on the effect desired. For instance, it may be desirable for reflectors to be grouped into various other geometric configurations such as: squares, circles, rectangles, triangles, etc. 
     A series of lamps of different hues are mounted in each reflector. In the illustrated embodiment, each reflector, such as the central reflector 22, has a base end or portion 22a with a central aperture 22b. A series of narrow slots 22c are equally spaced apart in the periphery of the aperture 22b to mount the lamps: F 2  R, F 1  G, F 5  Y, F 4  B, F 3  P (shown clockwise in FIG. 2). Preferably, each lamp such as the lamp F 4  B has a recess 41 providing a pair of spaced shoulders 42 and 43 engaging opposite sides of the base portion 22a of the reflector 22. With the foregoing structure, each lamp such as the lamp F 4  B can be mounted in position in the reflector 22 simply by pushing it forwardly through the aperture 22b and sliding it laterally in the slot provided therefor in the reflector base 22a into position. This structure facilitates removal and replacement of lamps. 
     In the disclosed embodiment, the lamps mounted in the reflectors are of different hues for each reflector. Each reflector should have five different hues, and three of the hues should be the three primary colors: red (R), blue (B), and yellow (Y). The remaining lamps in the series are preferably green (G) and pink (P). Clear lamps are not desirable. As will be described, the use in each reflector of the primary colors is highly desirable because of the various color blends which are produced when the assembly is in use. Also, as will be discussed, five lamp flashers are employed: F 1 , F 2 , F 3 , F 4 , F 5 . The lamp color and the flasher which controls the lamp color are therefor designated, for example, as in F 1  R, F 2  B, F 3  Y, F 4  G, and F 5  P, and combinations thereof. 
     It has been found that the various lamp hues should be placed in particular locations in the reflectors to obtain optimum performance. For instance, it is preferable for the lamps in the central reflector 22 to be grouped with a red hue at the 12 o&#39;clock position, a green hue at about the 2 o&#39;clock position, a yellow hue at about the 5 o&#39;clock position, a blue hue at about the 7 o&#39;clock position and a purple hue at about the 10 o&#39;clock position. In the inner ring of reflectors 23-28 surrounding the central reflector 22, the 12, 2 and 10 o&#39;clock positions have the yellow, red and blue hues, respectively, and the 5 and 7 o&#39;clock positions alternate purple and green hues in the clockwise direction beginning with the reflector 23 located at the 3 o&#39;clock position in the inner ring. In the outer ring of reflectors 29-40 surrounding the inner ring, the hues are distributed with the purple, green and yellow hues at the 12, 5 and 7 o&#39;clock position, respectively, and the red and blue hues alternating between the 2 and 10 o&#39;clock positions in the clockwise direction beginning at the reflector 29 located at the 3 o&#39;clock position in the outer ring. Although this distribution of lamps and hues has been found to give a pleasing effect, the distribution disclosed is given by way of example and is not intended to be limiting in any respect. 
     The various lamps are illuminated in a predetermined manner. For this purpose a series of lamp flasher units: F 1 , F 2 , F 3 , F 4 , and F 5  (FIG. 6) are provided corresponding in number to the number of lamps in each reflector. Each flasher unit, such as the flasher unit F 1 , is designed simultaneously to illuminate the lamps connected thereto such as the lamps F 1  R, F 1  B, F 1  G, etc. connected to flasher F 1  (FIG. 6). The flasher units are of a conventional design which causes them to power the lamps at random. Preferably, the flashers are of the type which are commonly used in conventional &#34;Christmas-tree&#34; lamp assemblies. In some of these assemblies the flashers have clear lamps; however, if these are used they are simply placed toward the rear of the frame 11 so as not adversely to affect the colors. The flashers are essentially identical in that the duration of each flash is short (a fraction of a second) and the flasher intervals are substantially equal. The flashers are not, however, synchronized, so that each operates independently of the other in point of time. 
     The lamps in the various reflectors are connected in a predetermined manner. To this end, circuit means connects a separate flasher to one lamp in each reflector and connects one lamp in each reflector with one lamp in each of the other reflectors. The circuit means is illustrated schematically in FIGS. 5 and 6. For instance, beginning at the central reflector 22, the lamp F 1  G in reflector 22 is connected to the lamp F 1  R in the reflectors 23, 28, 27, 26, 25 and 24 by the wire W 1 , substantially as shown. The lamp F 2  R in the central reflector 22 is connected via the wire W 2  to the lamps F 2  Y in the same reflectors. The other lamps in the central reflector 22 having the same subscripts, i.e., F 3 , F 4  and F 5  are similarly connected by wires W 3 , W 4 , and W 5 . These wires have, however, been omitted from FIG. 5 for purposes of clarity, and the wires W 1  and W 2  have been illustrated as a single line in FIG. 5 for purposes of clarity, it being understood that the wire W 1  consists of two leads and the wire W 2  -W 5  consisting of three leads each. (See FIG. 6.) The flasher F 5  is connected via a cord C to a plug P adapted to be plugged into 120 V.A.C. 60 cycle house current. 
     In the disclosed embodiment, each reflector is cylindrical and has a ratio of length to diameter of about 1.4 to 1. A preferred length for each reflector is about 5 inches. If desired, each reflector may taper slightly outward in the forward direction from its base in somewhat of a frusto-conical shape. 
     In operation, the plug P is plugged into a wall receptacle. After a brief period of warm-up for the flasher units F 1  -F 5 , the lamps in the various reflectors begin to flash in random. By virtue of the circuit connection of the lamps in the various reflectors, and the use of different colors, the random flashing produces various colors and color blends which do not repeat in any definite pattern. Hence, an almost infinite variety of colors and color patterns are produced. It has been found that when the device 10 is viewed in combination with background music, the effect induced on an observer may vary with the observer. For instance, some observers perceive the lamps as flashing in synchronism with the music. In other words, when the music has a fast rhythm, the lamps seem to flash quickly. When the music has a slow rhythm, the lamps seem to flash slowly. Other observers perceive the colors as flashing in synchronism with particular tones or blends. Still other observers perceive patterns of colors which appear to be synchronized with beat, tones, etc. Thus, the present invention now provides a decorative lighting display which is particularly entertaining when operated in conjunction with music. 
     While a preferred embodiment of the present invention has been described in detail, various modifications, alterations and changes may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
