Abstract
A method of manufacture for a lamp involves making up, separate from an envelope, a sub-assembly comprising a lead structure and a vitreous body that surrounds it. In one form of this method, particles of vitreous material are pressed into a mold cavity that surrounds the lead structure, thus forming a compact surrounding the lead structure. This compact is sintered in an inert atmosphere, thereby forming the sub-assembly. Thereafter, the sub-assembly is placed in an opening in the envelope, and a hermetic seal is made between the envelope and the vitreous body in the interface region between the envelope and the vitreous body.
