  • Modular lamp assembly and method of assembling same
    Patent number: 6193391
    Abstract: A modular lamp assembly and method of assembling same is provided. The modular lamp assembly includes a lamp/ballast subassembly and a reflector which is positioned in a space provided between the lamp and the ballast. The reflector is unassembled in relation to the lamp and the ballast so that if the lamp or ballast are defective, the reflector may be readily removed from the subassembly and placed between a lamp and ballast of a replacement subassembly. The lamp/ballast subassembly, including the reflector, are held in place within a housing by sandwiching the ballast and the reflector between interior surfaces of the housing and a housing cover which contains an opening aligned with the lamp.
