Abstract
A lamp inlead assembly for a light source having a lamp envelope with at least one end region in which the lamp inlead assembly is sealably disposed includes and outer lead wire member to which power to the light source is coupled, an inner lead wire member to which the light generating device is connected, whether incandescent or discharge, and a thin foil member disposed therebetween on which the inner and outer lead wire members are fixedly secured. The thin foil member is constructed of molybdenum and is essentially uniform in thickness throughout. At least one trough is formed in the foil member and is effective so as to: increase the surface area of the foil member and thus improve its current carrying properties without increasing the dimensional space within the end region of the lamp area to accommodate such increased surface area, provide increased rigidity for the foil member so that such foil member can be adapted for handling by high speed automated manufacturing equipment, and, with one trough centrally disposed along the width dimension of the foil member, insure that the positioning of the lead wire members relative to the foil member is maintained throughout the ma…
