This invention consists of an improved design and assembly process for the manufacture of a single ended quartz (SEQ) lamp (A) having three-part leads (14A,14B,14C;16A,16B,16C) and a prefocus base (12) for projection applications. This invention consists of a much simpler two-pin prefocus ceramic base SEQ lamp design that is made with fewer parts and is much easier and faster to assemble to enable much reduced labor and cost. Also, the ceramic base is smaller and exposes more of the quartz lamp seal (22) to the surroundings to enable more effective cooling during lamp operation to prevent lamp failures from overheated seals. Also, the ceramic base is designed for quick assembly with the filament 15 correctly focused to the base. <IMAGE> |
