Abstract:
1. A discharge lamp comprising: a discharge envelope containing a discharge-supporting fill; at least one pair of inner leads having at least a portion extending into the envelope and between which an electric discharge passes during operation of the lamp; for each inner lead, a corresponding outer lead passing through an end of the envelope; a substantially planar foil between a pair of corresponding inner and outer leads for creating an electrical connection there between; and a separate connector provided between any one lead and the substantially planar foil, the connector being attached to the lead and welded to the substantially planar foil such that a weld joint connecting the connector and the foil extends along substantially the entire width of the foil for preventing failure thereof during conditions of extreme heat and energy and fixedly secured to any one lead, the connector providing a planar contact surface and increasing a contact surface area and providing means for dissipating excess heat and energy entering the lamp through the lead.
