Abstract
Abstract A luminaire having a boxlike housing with a removable cover secured thereto. The luminaire's reflector, having the socket and lamp components located therein, is rotatable on a planar mounting plate, thus enabling two light output distributions (patterns) to be provided, each at about ninety degrees from the other. The preferred lamp is a high intensity discharge (HID) lamp (e.g., high pressure sodium).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
195 words
A luminaire comprising: a housing of substantially boxlike configuration and defining an opening therein; a component mounting plate of substantially planar configuration and secured to said housing substantially across said opening, said component mounting plate including an aperture therein defined by two pairs of opposed sides, the sides of a first of said pairs being of substantially straight configuration and the sides of a second of said pairs being of substantially curved configuration; a cover member secured to said housing for providing a cover for said opening, said cover member including a lens therein; a reflector rotatively positioned on said component mounting plate adjacent said aperture and capable of occupying at least two positions thereon each oriented at least about ninety degrees relative to the other, said reflector reflecting light through both said aperture within said component mounting plate and said lens; a socket secured to said reflector; and a lamp positioned within said socket and being located within said reflector, both said lamp and said socket thereby being rotated simultaneously with said reflector such that said luminaire is capable of providing light output distributions of at least two different orientations relative to said luminaire.
Claim 2
Dependent Claim
195 words
A luminaire comprising: a housing of substantially boxlike configuration and defining an opening therein; a component mounting plate of substantially planar configuration and secured to said housing substantially across said opening, said component mounting plate including an aperture therein defined by two pairs of opposed sides, the sides of a first of said pairs being of substantially straight configuration and the sides of a second of said pairs being of substantially curved configuration; a cover member secured to said housing for providing a cover for said opening, said cover member including a lens therein; a reflector rotatively positioned on said component mounting plate adjacent said aperture and capable of occupying at least two positions thereon each oriented at least about ninety degrees relative to the other, said reflector reflecting light through both said aperture within said component mounting plate and said lens; a socket secured to said reflector; and a lamp positioned within said socket and being located within said reflector, both said lamp and said socket thereby being rotated simultaneously with said reflector such that said luminaire is capable of providing light output distributions of at least two different orientations relative to said luminaire.
Claim 3
Dependent Claim
17 words
The luminaire according to claim 1 wherein said reflector includes a forward opening of substantially annular configuration.
Claim 4
Dependent Claim
34 words
The luminaire according to claim 2 wherein said reflector includes a substantially annular flange portion, said flange portion being positioned on said component mounting plate substantially about said aperture therein in a flush relationship.
Claim 5
Dependent Claim
36 words
The luminaire according to claim 3 wherein said reflector is secured to said mounting plate by a pair of retention screws, said screws being located within said mounting plate on opposite sides of said aperture therein.
Claim 6
Dependent Claim
19 words
The luminaire according to claim 3 wherein said reflector includes therein a plurality of reflecting surfaces of different configurations.
Claim 7
Dependent Claim
19 words
The luminaire according to claim 5 wherein said different configurations for said reflecting surfaces include parabolic, spherical and cylindrical.
Claim 8
Dependent Claim
23 words
The luminaire according to claim 1 wherein said reflector includes a reflecting wall having an opening therein, said socket passing through said opening.
Claim 9
Dependent Claim
29 words
The luminaire according to claim 7 further including a bracket secured to said reflector on an external surface thereof adjacent said opening, said socket being positioned on said bracket.
Claim 10
Dependent Claim
14 words
The luminaire according to claim 1 wherein said lens is of substantially round configuration.
Claim 11
Dependent Claim
14 words
The luminaire according to claim 1 wherein said lens is of substantially rectangular configuration.
Claim 12
Dependent Claim
21 words
The luminaire according to claim 1 wherein said light source is a high intensity discharge lamp having an elongated arc length.
Claim 13
Dependent Claim
27 words
The luminaire according to claim 11 wherein said high intensity discharge lamp is selected from the group consisting of high pressure sodium, metal halide and mercury lamps.
