ABSTRACT:
A replaceable light source assembly is particularly designed for use in a projector housing with sources such as an HMI arc lamp or tungsten halogen lamp where the light source is contained within an envelope. Basically, the light source is closely spaced to a substantially flat mirror which images the light source around the source to produce the effect of a multiplicity of sources. In effect, the light source and its mirror image produces a beam pattern which may be projected towards a suitable projection lens, the light source and mirror are fastened to a heat sink structure to dissipate heat, and the assembly has suitable electrical connections to fit existing housings.
