Abstract

Abstract An illumination system usable in a display cabinet includes a plurality of spaced apart, low-voltage lamps. The lamps are supported by a reflector off-set from a shell or housing. The air space created between the reflector and the shell or housing provides thermal insulation such that the system will not excessively heat the display cabinet.
