Abstract
Abstract A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals. The reflector includes a parabolic section the rear central portion of which is integrally formed with a boss. At least two slots are formed in the boss for receiving the terminals, and each slot is located in a cavity which is adapted to be filled with an adhesive for fixing the terminals to the reflector after the lamp assembly is optically aimed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals, said reflector including a parabolic reflective portion integrally formed with an upper wall and a lower wall, the rear central portion of said parabolic reflective portion being integrally formed with a boss having a substantially uniform thickness greater than the thickness of said parabolic reflective portion adjacent said boss, at least two cavities formed in the exterior portion of said boss; an opening formed in each of said cavities for receiving one of said terminals, each of said cavities being generally concave and stepped in cross-section and totally surrounds the associated opening, each of said openings being sized slightly larger than the cross-sectional configuration of said one of said terminals for allowing pivotal movement of said lamp assembly when said lamp assembly is being optically aimed relative to said reflector; said cavities adapted to accommodate an adhesive for fixing said terminals to said reflector after said lamp assembly is optically aimed.
Claim 2
Dependent Claim
169 words
A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals, said reflector including a parabolic reflective portion integrally formed with an upper wall and a lower wall, the rear central portion of said parabolic reflective portion being integrally formed with a boss having a substantially uniform thickness greater than the thickness of said parabolic reflective portion adjacent said boss, at least two cavities formed in the exterior portion of said boss; an opening formed in each of said cavities for receiving one of said terminals, each of said cavities being generally concave and stepped in cross-section and totally surrounds the associated opening, each of said openings being sized slightly larger than the cross-sectional configuration of said one of said terminals for allowing pivotal movement of said lamp assembly when said lamp assembly is being optically aimed relative to said reflector; said cavities adapted to accommodate an adhesive for fixing said terminals to said reflector after said lamp assembly is optically aimed.
Claim 3
Dependent Claim
195 words
A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals, said reflector including a parabolic reflective portion integrally formed with an upper wall and a lower wall, the rear central portion of said parabolic reflective portion being integrally formed with a boss having a substantially uniform thickness greater than the thickness of said parabolic reflective portion adjacent said boss, at least two cavities formed in the exterior portion of said boss; an opening formed in each of said cavities for receiving one of said terminals, a groove in each of said cavities which is generally concave and U-shaped in cross-section surrounding each of said openings and being located adjacent thereto so as to provide a stepped configuration when each of said cavities is viewed in cross-section, each of said openings being sized slightly larger than the cross-sectional configuration of said one of said terminals for allowing pivotal movement of said lamp assembly when said lamp assembly is being optically aimed relative to said reflector; each of said cavities adapted to accommodate an adhesive for fixing said terminals to said reflector after said lamp assembly is optically aimed.
Claim 4
Dependent Claim
195 words
A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals, said reflector including a parabolic reflective portion integrally formed with an upper wall and a lower wall, the rear central portion of said parabolic reflective portion being integrally formed with a boss having a substantially uniform thickness greater than the thickness of said parabolic reflective portion adjacent said boss, at least two cavities formed in the exterior portion of said boss; an opening formed in each of said cavities for receiving one of said terminals, a groove in each of said cavities which is generally concave and U-shaped in cross-section surrounding each of said openings and being located adjacent thereto so as to provide a stepped configuration when each of said cavities is viewed in cross-section, each of said openings being sized slightly larger than the cross-sectional configuration of said one of said terminals for allowing pivotal movement of said lamp assembly when said lamp assembly is being optically aimed relative to said reflector; each of said cavities adapted to accommodate an adhesive for fixing said terminals to said reflector after said lamp assembly is optically aimed.
Claim 5
Dependent Claim
213 words
A reflector for supporting a tungsten-halogen lamp assembly having a light bulb connected to a plurality of terminals, said reflector including a parabolic reflective portion integrally formed with an upper wall and a lower wall, the rear central portion of said parabolic reflective portion being integrally formed with a boss having a substantially uniform thickness greater than the thickness of said parabolic reflective portion adjacent said boss, a first cavity formed in the exterior portion of said boss; a pair of second cavities formed in said first cavity, a slot formed in each of said second cavities for receiving one of said terminals, each of said second cavities being generally concave in cross-section, a U-shaped groove located in said each of said second cavities and totally surrounding the associated slot closely adjacent thereto so as to provide a stepped configuration when said each of said second cavities is viewed in cross-section, each of said slots being sized slightly larger than the cross-sectional configuration of said one of said terminals for allowing pivotal movement of said lamp assembly when said lamp assembly is being optically aimed relative to said reflector; said first and second cavities adapted to accommodate an adhesive for fixing said terminals to said reflector after said lamp assembly is optically aimed.
