Abstract
Abstract Luminaire includes an assembly of a reflector and lamp socket holder which provides for a tight seal between the reflector and a refractor when the refractor is moved into closed position against the reflector, while maintaining a fixed relationship between the lamp and the reflector. The front end of the reflector is fixedly secured to the luminaire housing, and at the rear end of the reflector the lamp socket extending through an opening in the reflector is adjustably secured to a socket holder fixed to the reflector. A leaf spring attached to a fixed support urges the socket holder downwardly for maintaining the reflector rim gasket in firm engagement with the mating refractor rim in the closed position. Tabs on the socket bracket projecting over the fixed support serve to prevent the reflector from falling out of the housing when the refractor is dropped to open position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
A luminaire comprising, in combination, an elongated upper housing having a bottom opening, a concave reflector in said housing facing said opening, said reflector being elongated along the elongate axis of said housing and having front and rear ends, a refractor connected to said housing for movement between an upper closed position covering said reflector and in sealing relation therewith and a lower open position away from said reflector, said reflector having an opening at its rear end, a lampholder arranged extending through said reflector opening and adapted to support a lamp within said reflector, holder means fixed to said reflector at said opening thereof for holding said lampholder in predetermined fixed position relative to said reflector, and support means fixed to said luminaire housing and having resilient means engaging said holder means for urging the latter downwardly for yieldably holding said reflector in sealing relation with said refractor when the latter is in said closed position.
Claim 2
Dependent Claim
