ABSTRACT:
A lamp housing and socket assembly includes an injected molded plastic housing with an integral, axially outwardly directed collar and a radially inwardly directed light interception surface with a bulb access opening slightly larger in diameter than the maximum diameter of a bulb supported in a lamp socket; the lamp socket includes a plurality of locking ears on one end thereof and a sealing gasket; a standard socket mounting cap is supported on the collar to define a socket mount that can be universally used with mirrors having a range of focal lengths. The socket mounting cap includes an inboard flange supported on the outer periphery of the mirror collar and a large diameter outboard flange that shields the gasket; and the cap further includes a radially inwardly directed socket opening wall for receiving the locking ears for rotation with respect thereto to secure the socket and the lamp with respect to the housing; the arrangement minimizing socket hole light reflection losses thereby to minimize the light size requirements for producing a desired light output from the assembly.
