ABSTRACT:
This lamp comprises an envelope of vitreous light-transmitting material enclosing an internal space, light-generating means within said space, and conductive lead structure projecting into said space and comprising inner and outer lead members and a foil member connected between said lead members. A first portion of the envelope surrounds the foil member and is sealed thereto, and a second portion of the envelope is located inwardly of the first portion. A tubular bead of vitreous material is provided about the inner lead member. This bead fits within the second envelope portion, is joined thereto, and supports the inner lead member in a precise predetermined portion within the envelope. The inner lead member projects inwardly beyond the bead and provides support for the light-generating means.
