United States Patent 3,189,736 LIGHTING FIXTURE Walter M. Waldbauer, North Olmsted, Ohio, assignor to Westinghouse Electric Corporation, Pittsburgh, Pa, a corporation of Pennsylvania Filed May 21, 196 3, Ser. No. 281,916 7 Claims. (Cl. 240--3) This invention relates, generally, to lighting fixtures and, more particularly, to outdoor lighting fixtures, generally known as luminaires.

An object of the invention is to provide a luminaire suitable for the lighting of malls, campus type developments, parks, recreation areas, parking areas, residential and business streets, etc.

Another object of the invention is to provide an improved luminaire which may be readily attached to the top of a post or pole.

A further object of the invention is to provide an improved luminaire having a sectionalized refractor assembly.

Still another object of the invention is to provide a luminaire having a hinged cover or reflector which can be opened to permit optical members to be lifted out of the supporting housing of the luminaire.

A still further object of the invention is to provide spaced members extending from the housing for supporting the cover assembly and which merge into the general appearance of the luminaire.

Other objects of the invention will be explained fully hereinafter or will be apparent to those skilled in the art.

In accordance with one embodiment of the invention, an inverted generally frus'toconical-shaped housing may be attached to the top end of a pole by means of a single set screw. A sectionalized generally frustoconical-shaped refractor is mounted on top of the housing and a generally frustoconical-shaped diflfuser is mounted on top of the refractor. Four outer bars equally spaced around the housing are attached to the housing and extend to the top of the diifuser where they support a top ring to which a cover is hinged. The bars cover the joints between quadrants of the refractor. A door in the housing provides access to a ballast assembly inside the housmg.

For a better understanding of the nature and objects of the invention, reference may be had to the following detailed description, taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is a view, partly in elevation and partly in section, of a luminaire embodying the principal features of the invention;

FIG. 2 is a detail view of a latch for the cover of the luminaire;

FIG. 3 is an enlarged view, partly in section and partly in elevation, of the metal housing for the luminaire;

FIG. 4 is a top plan view of the housing;

FIG. 5 is an enlarged view, in plan, of a top ring for the luminaire;

FIG. 6 is a view, partly in section and partly in elevation of the ring shown in FIG. 6;

FIGS. 7, 8 and 9 are detail views of the hinge for the cover of the luminaire; and

FIG. 10 is a view, partly in section and partly in elevation, of a modification of the luminaire shown in FIG. 1.

Referring to the drawings, and particularly to FIG. 1, the luminaire shown therein comprises a housing 10, a refractor assembly 11, a diffuser 12, a top ring 13, a cover 14, and four bars which are equally spaced around the outside of the luminaire. As shown, the luminaire may be mounted on top of a post or pole 16.

The housing 10 is preferably cast from aluminum or other suitable material. As shown most clearly in FIGS. 3 and 4, the housing is generally frustoconical in shape, open at both ends, and is mounted in an inverted position with the end having the smaller diameter at the bottom and the end having the larger diameter at the top.

The housing is provided with three equally spaced, integrally formed internal ribs 17 at its bottom end for mounting the housing on the pole 16. Each rib 17 has an inwardly extending projection 18 thereon for engaging the top of the pole. A threaded opening 19 is provided in one rib 17 for receiving a set screw 21, shown in FIG. 1, for attaching the housing to the pole 16.

The housing 10 is also provided with four equally spaced internal shoulders 22 at the top of the housing. Each shoulder 22 has an upwardly extending projection 23 thereon. The shoulders 22 support the refractor assembly 11. Oppositely disposed bosses 24 are provided on the inside of the housing 10. The bosses 24 support a lamp holder 25 and a ballast assembly 26. A door 27 is provided for an opening 27 in the housing 10 between two of the vertically extending bars 15 to permit access to the ballast assembly 26. Four equally spaced external projections 28 extend longitudinally of the hous- 10. One of the bars 15 is attached to each projection 28 by screws 29, as shown in FIG. 1, which are threaded into holes 3% in the projections 28.

The refractor 11 and the dilfuser 12 are preferably composed of plastic material. However, they may be composed of glass if desired. The refractor 11 is preferably made in four quadrants which are held assembled by bands or wires 31 disposed in grooves at the top and/ or bottom of the refractor assembly. The refractor is generally frustoconical in shape and is mounted with the small end at the bottom and the large end at the top.

' The refractor can be made in one piece if desired. However, a wide variety of light distribution can be achieved by suitable arrangement of various quadrant sections. As previously explained, the refractor assembly is supported by the shoulders 22 on the housing 10.

The diffuser 12 is preferably made in one piece. It is also generally frustoconical in shape and is disposed at the top of the refractor assembly with the small end of the diffuser resting on the top of the refractor 11. The diffuser is provided with insert portions 32 in order to clear the bars 15.

As shown in FIG. 1, the top ring 13 encircles the top of the diliuser 12. The ring 13 is supported by the four bars 15 to which it is attached at the top of the bars by screws 33. The cover 14 is mounted on the ring 13 by means of a hinge 34. As shown in FIG. 5, the ring 13 has two spaced projections 35 thereon for receiving the hinge member 34 which is retained between the projections 35 by means of a pin 36.

The hinge member 34 is shown in FIGS. 7, 8 and 9. It is attached to the cover 14 by screws 37 which may be threaded into tapped openings 38 in the hinge member. The hinge member has an opening 39 therethrough for receiving the pin 36 to retain the hinge member between the projections 35 on the ring 13.

The cover 14 is preferably formed from sheet aluminum. It may be painted a suitable color on the out-side and reflecting white on the inside. As shown most clearly in FIGS. 1 and 2, the cover 14 is retained closed by means of a latch assembly 41. The latch assembly 41 comprises a short bar 42 attached to the cover 14 by a screw 44. The bar 42 is engaged by a screw 46 held captive by a washer 45 in a lateral projection 47 on the top ring 13. The screw 46 may be of the quick release type.

As shown in FIGS. 5 and 6, the projection 47 has an opening 48 therein for receiving the screw 46. The projection 47 is located diametrically opposite the hinge member on the ring 13. The ring 13 has tapped openings 49 therein for receiving the screws 33 for attaching the ring to the outer bars 15. When the cover 14 is opened thethe diffuser 12 has spaced upwardly extending projections 52 (see FIG. 2) around its top. In this manner clearance is provided between the main portions of the ring 13, the diffuser 12 and the cover 14. Also, the bottom opening of the housing for the pipe 16 islarger than the pipe, thereby permitting air to enter between the ribs 17 at the bottom of the housing. Heat from the lamp creates a chimney edect causing the air to rise. The hot air is exhausted between the diffuser and the cover, and between the ring and the cover.

If automatic control of the luminaire is desired, a photocontrol unit 55 may be mounted on the top of the cover 14 as shown in FIG. 1. The photocontrol unit comprises a receptacle 56 which is retained in an opening in the cover 14 by means of an adapter 57 which is attached to the cover by screws 58. A gasket 59 may be provided between a flange on the receptacle 56 and the cover 14.

The outer bars 15 are generally U-shaped in crosssection. The wires from the photocontrol unit 55 may be disposed inside one of the bars 15 to connect the photocontrol unit with the ballast equipment in the housing. The bars 15 are disposed over the 'joints between quadrants of the refractor 11, thereby concealing the joints. The bars extend from near the bottom of the housing to the top ring 13.

The modified luminaire shown in FIG. 10 is similar to the one shown in FIG. 1 with the exception that the housing does not contain the ballast equipment. Accordingly, the housing 10' shown in FIG. 10 is shorter in length than the housing 10 shown in FIG. 1. The housing 10' is attached to a pole 16 in the same manner as the housing 10. The outer bars 15 in the structure shown in FIG. 10 are shorter than the bars 15 in FIG. 1 since they extend only from near the top of the housing 10' along the refractor *11 and the diffuser 12 to the top ring .13 to which they are attached in the manner hereinbefore described. The refractor 11 is supported by the housing 10' in the manner hereinbefore described and the diffuser 12 is mounted on top of the refractor 11 as previously described.

Fromthe foregoing description it is apparent that the invention provides a luminaire which may be readily attached to the top of a supporting post or pole. The internal ribs provided in the housing for supporting the luminaire insure good alignment with the pole. The sectionalized refractor permits flexibility of light control and distribution. The hinged top cover, which also functions as a reflector, permits the plastic components to be lifted out for cleaning and also permits lamp replacement. The four bar system for supporting the top members of the luminaire merges into the general appearance of the luminaire. The bars also provide a raceway for the wires from the photocontrol unit when one is utilized. When the longer housing is provided, the ballast equipment may be mounted inside the housing.

Since numerous changes may be made in the above described construction, the different embodiments of the invention may be made Without departing from the spirit and scope thereof. It is intended that all matter contained in the foregoing description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
