COMBINATION STRIP LIGHT Filed Aug. 2. 1966 I Sheet of 2 INVENTOR.
RICHARD C. PICCOLA 5y ATTORNEYS Feb. 25, 1969 R. c. PICCOLA COMBINATION STRIP LIGHT Filed Aug. 2, 1966 INVENTOR. RICHARD I C. PICCOLA ATTORNEYS United States Patent 7 Claims This invention relates generally to a combination strip light and more particularly to an arrangement for supporting incandescent and fluorescent lighting apparatus for preselected combinations of such lighting apparatus in accordance with the illumination requirements of any particular situation.
Fluorescent ligthing for general area illumination is of course well known with such lighting providing for generally uniform dispersion of light throughout a wide area. For emphasis in a particular area or for a particular subject it is desirable to spot light the area thereby raising the lumens incident on a particular point. This may preferably be done with incandescent lighting apparatus whose direction can more easily be controlled.
In prior art lighting, it has generally been necessary to provide a plurality of apparatus or fixtures for the various lighting requirements, viz a series of fluorescent fixtures for general illumination and variously placed incandescent fixtures for highlight illumination.
As may well be understood, in any particular installation, the cost of the installed lighting fixtures will be directly proportional to the number of fixtures based on the cost per fixture as well as the cost for structurally mounting and electrically connecting each fixture.
Accordingly, it is an object of this invention to provide an improved strip light which, in a single fixture, includes means for providing general area illumination as well as means for providing highlight illumination.
Another object of the invention is to provide an improved fixture including both fluorescent and incandescent illumination.
A further object of the invention is to provide an improved strip light which requires only a single structural installation and which includes at least one fluorescent light source and one incandescent light source.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
Generally speaking, in accordance with the invention, a housing is provided for supporting electrical elements capable of starting and illuminating at least one fluorescent tube. In combination with portions of said housing is at least one incandescent socket assembly which is preferably swively mounted so that the direction of the spot light carried thereby can be physically controlled in contradistinction to the fixed general illumination mounting of the fluorescent tube.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.
For a fuller understanding of the invention, reference is had to the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is an exploded perspective view of a combination strip light constructed in accordance with a preferred embodiment of the invention; and
FIGS. 2 through 6 are schematic plan views of various representative combinations of fluorescent/incandescent lighting possible in accordance with the teachings of this invention.
Patented Feb. 25, 1969 "ice Referring to FIG. 1, a housing 11 is formed as a U- shaped member having legs 12 and a base 13. The length of housing 11 is the developed length of the total strip taking into account the number and location of incandescent and fluorescent elements to be carried thereon. A U- shaped end plate 14 is provided at each end of housing 11 for selectively closing the end of the housing in order to give the strip a finished appearance. The end plate 14 may be secured to housing 11 by means of screws 15. While formation of the end plate as part of the formed housing is possible, it is preferable to form the end plate as a separate unit so that the end plates of contiguous strips may be omitted if it is desired, in a particular installation, to run a series of strips in alignment. In such event, end plates need only be provided for the outer most ends of the two end strips of a contiguous series.
A ballast 16 is secured, by any suitable means, to base 13 Within legs 12. A face plate 17 having in-bent legs 18 from which project elongated cars 19 is provided for, in the embodiment shown in FIG. 1, each end of housing 11. Suitable slots 21 are provided in legs 12 for receiving elongated ears 19 to thereby support face plate 17 on the housing with the outside surface of the face plate substantially flush with the end faces of legs 12.
A fluorescent lamp holder harness 22 is suitably secured to each face plates 17 with the open portions of the harness facing one another. The ballast and the harnesses are suitably wired in a manner well known in the art.
Extending between face plates 17 and secured thereto is a cover 23 which also acts as a reflector. The cover has in bent legs 24 which extend over the outsides of housing legs 12 with the cover being secured to the face plates by means of suitable screws 20. The cover not only acts to give the strip an attractive appearance by covering the ballast and internal wiring, but the outside surface thereof also acts as a reflector for dispersion of the light.
A fluorescent tube 25 has its ends mounted in harnesses 22 and extends over cover 23.
In the FIG. 1 embodiment, a single fluorescent and double incandescent light sources are provided. A swivel support 26 is mounted to the surface of face plate 17 beyond harness 22 and carries a socket 27 adapted to receive an incandescent bulb. Socket 27 is provided with suitable wiring (not shown) for electrical connection of the socket into the lighting circuit. Socket 27 may carry a reflector of any known type to be used in conjunction with a standard incandescent bulb or with an incandescent bulb internally fabricated with a reflector portion, in which event the external reflector may be omitted, if desired. Swivel support 26 may be of any known type and is preferably of the type which receives the socket wiring therethrough in order to provide an attractive, finished appearance to the strip light.
With the strip light of FIG. 1 installed, general illumination is possible by means of the single fluorescent tube 25 and highlighting may be accomplished through bulbs mounted in sockets 27. Such a combination strip light would be especially useful in a retail establishment where the incandescent lighting can be used to highlight articles on display. Thus the provision of a swivel mounting for the incandescent socket is of considerable importance so that the areas highlighted can be changed, if desired, as displays are changed from time to time.
When wiring the combination strip light shown in FIG. 1, flexibility is provided so that each of the three light sources may be separately switched, switched as a unit or switched in any combination to provide the controls desired in any particular installation.
FIGS. 2 through 6 schematically show in plan view various combinations of fluorescent and incandescent lighting possible in accordance with this invention. The showing of FIGS. 2 through 6 is for purposes of illustration and by no means limiting since, once having understood the invention, one skilled in the art could develop an almost unlimited array of fluorescent and incandescent source combinations.
Thus, FIG. 2 shows a combination strip light having a single incandescent and a single fluorescent light source while FIG. 3 shows a combination strip light having two fluorescent light sources located on opposite sides of a single incandescent light source. The combination strip light shown in FIG. 4 incorporates the arrangement shown and described in connection with FIG. 1 wherein a single fluorescent light source is mounted in the combination strip light with two incandescent sources, one on each end of the fluorescent source. FIG. 5 shows a combination strip light with two fluorescent light sources interposed between three incandescent light sources and FIG. 6 shows a combination strip light having two incandescent light sources and two fluorescent light sources with the fluorescent light sources being contiguous.
It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efiiciently attained and, since certain changes may be made in the above constructions without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
