1 SUSPENDED OUTDOORLIGHTING FIXTURE BACKGROUND OF THE INVENTION the surrounding area from rain and snow.

SUMMARY OF THE INVENTION The present invention providesan improved outdoor lighting fixture particularly adapted for use on a gasoline service station island, whichlighting fixture has a pleasing and distinctive appearance. for the purpose of attracting and maintaining customers, and is of sturdy construction with the lights themselves being enclosed in a protective annular housing having'a' solid bottom. The annular housing is disposed around a center post and appears to be suspended in space around the post without readily visible means of support. The supports for the housing are relatively narrow members which extend radially outwardly from the center post to the housing and from a distance are not readily visible because of the surrounding housing. The lighting fixture is utilized in conjunction with a large light rays One of the principal objects of the present invention is to provide an improved outdoor lighting fixture having a pleasing and distinctive appearance and which is of sturdy construction and yet which may be easily installed and serviced. Another object of the invention is "to provide a lighting fixture in which the lights are sub- FIG. 2 is a view taken on. line 2-2 of FIG. 1 and.

shows half of the lighting fixture inplan view and half in horizontal section.

FIG. 3 is a vertical cross sectional view taken on the line 3-3 of FIG. 2. I

FIG. 4 is a vertical cross sectional view taken through one of the lights on the line 4-4 of FIG. 2.

FIG. 5 is a vertical cross sectional view taken on the line 5-5 of FIG. 2. Referring now to the drawings, and more particularly to FIG. 1, reference numeral 10 generally designates the lighting fixture of the invention which is suspended concentrically around and supportedon a hollow vertical center post 12. The lower end of post 12 is embedded within the concrete footing of a service station island 14. A large canopy 16 is supported upon the upper end of post 12 and overhangs the island 14 and the adjacent paved areas 18. The underside of the canopy is an outwardly and upwardly inclined light reflective surface 20. Light rays fromthe lighting fixture 10 are cast upwardly and reflected downwardly off the reflective surface 20 onto the paved areas 18 as schematically illustrated in FIG. 1 by arrows.

As seen in FIG. 2, the lighting fixture 10 includes an annular sheet metal housing which is made in two halfs which are fastened together. Each half of the housing includes a vertical arcuate outer wall 22, a smaller arcuate inner wall 24, a pair of straight connecting wall portions 26 which lie in a common plane, and a light impermeable bottom 28.

A pair of substantially. rigid support bars 30 which each have an arcuate center portion 32 having a size slightly larger than the outside diameter of post 12 are bolted to each other by bolts 34 with gaskets 36 clamped between the outer surface of post 12 and the central sections of the center portions 32 of the support bars. The two housing halfs are mounted upon the support bars 30 by passing screws 38 through the mating connecting wall sections 26 of each half and through holes in the support bars 30 as best seen in FIG. 3.

Four metal are lamps 40 of a suitable size, e.g., 400 watts, are positionedin the housing employing sockets 42 and junction boxes 44. Aluminum reflectors 46 disposed below each lamp 40 reflect its rays upwardly.

Current is supplied to the lamps via electrical conduits 48 which pass up through the hollow post 12, outwardly through holes in post 12 and one of the gaskets 36 which as shown in FIG. 2 is the gasket atthe left side of the center post into one of a pairof small duct housings 50 which may be integrally connected to the center portions 32 of the support bars. A conduit 48 then extends arcuately in the annular space within the inner housing wall 24, through holes in bars 30 to the other duct housing 50. The duct housings include outer annular walls 52 which abut against the adjacent regions of the inner housing walls 24. As best seen in FIG. 5, the electrical conduits 48 extend through the duct housings to duplex connectors 54 which are threadably disposed in apertures in the outer duct housing wall 52 and in the inner housing wall 24 by means of a complementarily threaded nut member 56 and an abutment member 58. Electrical conduits 60 extend from the duplex connectors 54 to the junction boxes 44 in the respective halfs of the housing. To facilitate assembly and repair, access may be had to the duct housings 50 via removable covers 62 which are normally secured in position by screws 64 or other comparable securing means.

The top of the annular housing is closed off by light transmitting heavy duty Pyrex glass panes 66. The glass panes are disposed within U-shaped inner and

outer channel members

68 and 70 by being embedded in

silicone sealant masses

72 and 74, respectively. It is presently preferred to provide a small opaque band 75 at the inner periphery of the glass panes 66, for example, bypainting this portion of the underside of the panes with white paint. This causes a preferred distribution of the light rays emanating from lamps 40 upwardly to the light reflective surface 20 of the canopy.

As illustrated in FIG. 5, the inner channel member 68 is detachably connected to a horizontal lip 76 formed by bending over the upper edge of the inner housing wall 24. In the illustrated embodiment, the securing means comprise a Neoprene gasket sealing strip 78 disposed between the channel member and the lip 76, a metal strip 79 disposed beneath the lip 76, a nut member 80 which has a tapering upper portion disposed within a correspondingly tapered aperture in lip 76, a bolt 82 threadably engaging the nut member 80, and a plastic cap 84 at the lower end of the nut member 80.

The outer channel member 70 (see FIG. 4) is similarly connected to an inwardly extending horizontal lip 86 which is integrally connected to the outer housing wall 22 by means of a gasket strip 88 an inverted U-shaped channel member 90, and a bolt 82 and nut members 80 as described in connection with the securement of the inner channel member 68.

For ventilation purposes, a plurality of small louvered plugs 92 shown in FIGS. 3 and 5 are provided in the inner housing wall 24. Drain holes 94 (FIG. 3) in the bottom of the annular housing allow any water which enters the housing to drain out of the housing.

While a presently preferred embodiment of the invention has been described with particularity, it will be appreciated that various changes and modifications may readily suggest themselves to those of ordinary skill in the art on being apprised of the present invention. It is intended to cover all such changes and modifications as fall within the scope and spirit of the appended claims.
