The invention concerns an electric lamp, particularly a high-pressure disrge lamp or halogen bulb with a base on one side for a motor-vehicle headlight. The base of the lamp of the invention has a base sleeve (110) comprised of an electrically insulating material and a mounting element (111) also comprised of an electrically insulating material, which bears lamp bulb (116) and which is joined with base sleeve (110). According to the invention, a metal part (121) is anchored in mounting element (111) and a metal ring (122) is anchored in base sleeve (110), whereby metal ring (122) is equipped with several shaped spring-type weld lugs (122), which are welded with metal part (121) anchored in mounting element (111).

Disclosed is a lamp, particularly for a vehicle headlight, comprising two spiral-wound filaments which are retained by three feeders within a bulb that is inserted into a base. The feeders are arranged on top of one another when the lamp is adequately oriented. A tail of the first spiral-wound filament is connected to a dimming cap, said tail being located at a distance from the base, while a tail of the second spiral-wound filament is connected to the central feeder, said tail being close to the base. The second filament tail that faces away and is located at a distance from the base is connected to the upper feeder. According to the invention, the lower feeder is connected to the dimming cap by means of an end, some sections of which are angled away from a longitudinal axis of the lamp.

The invention relates to a lamp base comprising a plastic base part (320) that is provided with electric connections (61, 62, 63) for supplying power to at least one luminous means (21, 22) of the lamp that is surrounded by the lamp vessel (10). The electric connections (61, 62, 63) comprise contact sections (610, 620, 630) for connecting to power supply lines (51, 52, 53) of the at least one luminous means (21, 22), that protrude from the lamp vessel (10), and the lamp base is equipped with a sealing element (330) for covering the contact sections (610, 620, 630), said sealing element being fixed to the plastic base part (320) by a detent connection (3213, 3223, 3311, 3312, 3321, 3322). Said detent connection is preferably concealed. Said lamp base can be used, for example, in a motor vehicle headlight.
