Abstract
Abstract A street-lighting luminaire having an enclosed optical system adapted for containing a vertically burning mercury vapor lamp. The luminaire includes an overhead housing assembly separated by a dish-shaped reflector from a downwardly depending sealed optical assembly. A ballast assembly, socket mounting and positioning assembly and luminaire mounting bracket are located within the overhead housing assembly. The socket mounting and positioning assembly is mounted on the reflector within the overhead housing assembly and is constructed and arranged to provide for the horizontal and vertical adjustable repositioning of a lamp socket which is mounted on the lamp mounting and positioning assembly and which extends, through an aperture centrally located in the reflector, into the sealed optical assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A street-lighting luminaire comprising: a top housing assembly and a downwardly depending optical assembly, a dish-shaped reflector secured to said top housing assembly separating said top housing assembly from said optical assembly and having an elongated aperture therein located substantially centrally thereof, lamp socket means extending through said aperture in said reflector adapted to receive a vertically burning light source, socket-mounting and positioning means releasably secured to said reflector adjacent said aperture by a first adjustment means and having thereon second adjustment means for releasably securing said lamp socket means, in a vertical orientation, to said socket-mounting and positioning means, said first adjustment means selectively adjusting the lateral position of said lamp socket means with respect to said reflector and said second adjustment means selectively adjusting the vertical position of said lamp socket means into or out of said optical assembly.
Claim 2
Dependent Claim
141 words
A street-lighting luminaire comprising: a top housing assembly and a downwardly depending optical assembly, a dish-shaped reflector secured to said top housing assembly separating said top housing assembly from said optical assembly and having an elongated aperture therein located substantially centrally thereof, lamp socket means extending through said aperture in said reflector adapted to receive a vertically burning light source, socket-mounting and positioning means releasably secured to said reflector adjacent said aperture by a first adjustment means and having thereon second adjustment means for releasably securing said lamp socket means, in a vertical orientation, to said socket-mounting and positioning means, said first adjustment means selectively adjusting the lateral position of said lamp socket means with respect to said reflector and said second adjustment means selectively adjusting the vertical position of said lamp socket means into or out of said optical assembly.
Claim 3
Dependent Claim
42 words
A street-lighting luminaire according to claim 1 wherein gasket means is positioned about said lamp socket means between said socket-mounting and positioning means and said reflector for closing off the area of said elongated aperture not filled by said lamp socket means.
Claim 4
Dependent Claim
158 words
A street-lighting luminaire comprising: a top housing assembly and a downwardly depending optical assembly, a dish-shaped reflector secured to said top housing asSembly separating said top housing assembly from said optical assembly and having an elongated aperture therein located substantially centrally thereof and a pair of smaller elongated apertures parallel to said elongated central aperture on each side of said elongated centrally located aperture, lamp socket-mounting and positioning means, means for releasably securing said lamp socket-mounting and positioning means to said reflector through said smaller elongated apertures and for providing adjustable lateral selective positioning of said lamp socket-mounting and positioning means with respect to said reflector, a lamp socket mounted on said lamp socket-mounting and positioning means and extending through said larger elongated aperture in said reflector into said optical assembly, said socket-mounting and positioning means releasably retaining said lamp socket in a vertical orientation for vertical repositioning of said lamp socket with respect to said optical assembly.
Claim 5
Dependent Claim
158 words
A street-lighting luminaire comprising: a top housing assembly and a downwardly depending optical assembly, a dish-shaped reflector secured to said top housing asSembly separating said top housing assembly from said optical assembly and having an elongated aperture therein located substantially centrally thereof and a pair of smaller elongated apertures parallel to said elongated central aperture on each side of said elongated centrally located aperture, lamp socket-mounting and positioning means, means for releasably securing said lamp socket-mounting and positioning means to said reflector through said smaller elongated apertures and for providing adjustable lateral selective positioning of said lamp socket-mounting and positioning means with respect to said reflector, a lamp socket mounted on said lamp socket-mounting and positioning means and extending through said larger elongated aperture in said reflector into said optical assembly, said socket-mounting and positioning means releasably retaining said lamp socket in a vertical orientation for vertical repositioning of said lamp socket with respect to said optical assembly.
Claim 6
Dependent Claim
51 words
A street-lighting luminaire according to claim 3 wherein said lamp socket-mounting and positioning means includes a baseplate member overlying said larger elongated aperture and an upstanding socket-mounting flange and clamping-band assembly, said mounting-flange and clamping-band assembly permitting the selective vertical positioning of said lamp socket with respect to said optical assembly.
Claim 7
Dependent Claim
55 words
A street-lighting luminaire according to claim 4 wherein said baseplate member is adjustably secured to said reflector by means of said smaller elongated apertures to permit lateral movement of said lamp socket-mounting and positioning means with respect to said reflector to thereby permit selective horizontal positioning of said lamp socket with respect to said reflector.
Claim 8
Dependent Claim
36 words
A street-lighting luminaire according to claim 5 wherein gasket means is situated between said baseplate member and said reflector seal off communication between said housing and said optical assembly through said elongated apertures in said reflector.
