    (54) Electric lamp


    (57) An electric lamp having a light source (3) disposed in a light transmissive envelope (1), conductive lead-throughs (4) extending from said light source through the envelope to the exterior, and a lamp base (9) having contact terminals (20, 21) connected to the lead-throughs by clamping between two clamping portions (24, 26) of the terminals and welding of the clamping portions at two opposing surfaces of the lead-through (4). The terminals (20, 21) have a plating (27) with a melting point low enough such that the plating forms a brazed joint with the lead-through when a welding current from a resistance welder is passed through the clamping portions and the respective lead-through.
