ABSTRACT:
A high temperature tungsten halogen lamp having improved lamp strength so as to reduce lamp breakage. The ceramic base for supporting the press sealed end of the lamp's envelope has a top thereof including a pair of upwardly projecting members that extend above the press sealed portion to contact the bulb portion of the lamp envelope (or capsule). These corner projecting members enable enhanced support while at the same time providing a pair of windows therebetween to enable sufficient heat dissipation (thus preventing excessively high lamp seal temperatures). In accordance with the method of the invention the envelope is cemented to the ceramic base in a two-step operation including firstly cementing the base below the projecting members to bind the base to the envelope's press sealed portion and thereafter cementing the projecting members to the envelope's bulb portion.
