ABSTRACT:
An improved sealing construction is provided for an all glass lamp unit utilizing lens and reflector members which enhances the mechanical strength and hermetic seal when these lamp components are fusion sealed together. Specifically, the sealing rim surfaces of said lamp components are each provided with cooperating and opposing rib elements to permit direct physical abutment therebetween and thereby avoid forming void spaces in the sealing rim region when the fusion seal is made.
