Embodiment Construction

[0017] A lampholder 1 according to the invention is preferably used in motor vehicles and there in headlights. In this exemplary embodiment, the lampholder 1 has, on the one hand, an annular element 2 made of plastic material, which is molded or injected onto a reflector 4 in a top region 3 thereof. The ring element 2 has a plurality of axially and / or radially protruding protrusions 7 which, in the assembled position, enable the base of a lamp or the igniter 6 to be fixedly connected to the igniter 6 to be positioned correctly. ground on the reflector 4.

[0018] On the other hand, the base 1 has a tubular base body 8 made of electrically conductive material. The tubular base body 8 has a cylindrical section 9 with a plurality of detent elements 10 distributed in the circumferential direction, which correspond to corresponding detent elements 11 arranged on the outside on the ring element 2 . cooperate so that the base body 8 is detachably fastened to the ring element 2 . T...

Abstract

The lamp receiver (1) has a ring element (2) for the arrangement of a socket of a lamp, where the ring element has a radial receiving surface. A tubular bulb fitting body is made of an electrically conductive material. The tubular bulb fitting body has multiple contact springs (14) that are arranged in circumferential direction to a side facing a reflector and has other contact springs that are arranged in circumferential direction to another side facing an ignition device (6).

Description

technical field [0001] The invention relates to a lamp holder for a headlamp, in particular for a motor vehicle, comprising an annular element with a radial bearing surface for supporting the base of the lamp and a tubular base body made of an electrically conductive material , in the assembled position of the lamp, the tubular base body extends between a conductive section of a reflector and a conductive housing for an igniter of the lamp, wherein the tubular base body is equipped with a device for locking the lamp Fixing mechanism in assembled position. Background technique [0002] Known from EP 1 801 494 B1 is a lampholder for headlights, which comprises a tubular base body made of an electrically conductive material, in which a reflector and an igniter for the lamp extend in the area between. The tubular lamp base body is equipped with a securing mechanism for locking the lamp in the assembled position. Furthermore, the lampholder comprises an annular element having ...
