Abstract
Abstract A luminaire includes a generally parallelepipedic housing with a square opening into which a reflector and lamp assembly can be inserted and fastened. The opening is square as is the reflector so that it can be extracted and rotated 90° as a unit. The reflector has a parabolic concave reflective surface and a lamp with an elongated light source, producing a rectangular pattern which is rotated as the orientation of the reflector is rotated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A luminaire comprising the combination of a housing having a generally parallelepipedic shape and a square open side; a mounting device fixedly attached to an exterior surface of said housing; a reflector having a curved, concave reflective surface and a square periphery dimensioned to be received in said open side in any of its four orientations; a lamp socket mount attached to said reflector and extending rearwardly thereof: a lamp having an elongated light source therein; a lamp socket attached to said mount and extending through said reflector to hold said lamp in front of said concave surface; and fastener means for removably attaching the assembly comprising said reflector, mount, lamp and socket to said housing in any selected one of said orientations.
Claim 2
Dependent Claim
123 words
A luminaire comprising the combination of a housing having a generally parallelepipedic shape and a square open side; a mounting device fixedly attached to an exterior surface of said housing; a reflector having a curved, concave reflective surface and a square periphery dimensioned to be received in said open side in any of its four orientations; a lamp socket mount attached to said reflector and extending rearwardly thereof: a lamp having an elongated light source therein; a lamp socket attached to said mount and extending through said reflector to hold said lamp in front of said concave surface; and fastener means for removably attaching the assembly comprising said reflector, mount, lamp and socket to said housing in any selected one of said orientations.
Claim 3
Dependent Claim
30 words
