A lamp unit has a reflector ( 62 ) having a reflector surface ( 64 ) with an inverted U-shaped aperture ( 66 ) formed therein and extending through said reflector to an opposite surface ( 68 ). The inverted U-shaped aperture thereby has a bight ( 72 ) uppermost with a pair of channels ( 74, 76 ) depending therefrom. A light-shield has a cup-shaped member having an arm ( 52 ) projecting therefrom. The arm ( 52 ) has a distal end ( 50 ) formed to provide a pair of spring-loaded nibs ( 54, 56 ) for engaging and penetrating the channels ( 74, 76 ) of the inverted U-shaped aperture ( 66 ) and surrounding and grasping the bar ( 78 ) formed between the channels.
1. A lamp unit comprising:
a reflector having a reflector surface with an inverted U-shaped aperture formed therein and extending through said reflector to an opposite surface, said inverted U-shaped aperture thereby having a pair of channels depending therefrom; and defining a bar therebetween; and
a light-shield comprising a cup-shaped member having an arm projecting therefrom, said arm having a distal end formed to provide a pair of spring-loaded nibs for engaging and penetrating said channels of said inverted U-shaped aperture and encompassing said bar to fix the position of said light-shield relative to said reflector.
2. The lamp unit of claim 1 wherein said inverted U-shaped aperture has an entrance side and an exit side and said entrance side is provided with a stop that cooperates with mating stop edges formed in said nibs and determines the degree of penetration of said nibs into said channels of said inverted U-shaped aperture.
3. The lamp unit of claim 1 wherein said nibs have a transverse bar connecting them for part of their length and said transverse bar is provided with a tensioning spring.
