Embodiment Construction

[0037] figure 1 In particular, a motor vehicle headlight is shown with a housing 12 and a transparent dust cover 14 which covers the housing in a light emission direction 16 . Arranged within the housing 12 is at least one lighting module 18 which has a reflector 20 with a gas discharge lamp 22 . In one embodiment, the light emitting module 18 is a turn signal module, and its reflector 20 is universally suspended in the casing 12 . exist figure 1 In this case, the reflector 20 is rotatable within the frame 21 about a horizontally extending axis in order to allow adjustment of the headlamp. Furthermore, the frame is rotatable about a vertically extending axis 23 in order to allow the turn signal function. However, the invention is not limited to a lighting module 18 having the function of a turn signal, but can generally be used in a headlamp having: a reflector; a reflector neck arranged to accommodate a gas discharge Lamp; clamping mechanism arranged to clamp a gas discha...

Abstract

The present invention relates to a motor vehicle headlight (10) which has a reflector (20), a reflector neck (26)which is designed to incorporate a gas discharge lamp (22), and a clamping unit (24), which is designed to clamp the gas discharge lamp on the reflector neck(26). The gas discharge lamp (22) is designed to serve as retainer for a separate ignition device (30) and locked with the ignition device (30). The motor vehicle headlight (10) is characterized in that the clamping unit (24) is connected with the reflector (20) such that a movement of the clamping unit (24) in locked ignition device (30) required for loosening the clamping unit (24) is blocked by the ignition device (30).

Description

technical field [0001] The invention relates to a motor vehicle headlamp having: a reflector; a reflector neck arranged to receive a gas discharge lamp; a clamping mechanism arranged to clamp the gas discharge lamp in On the neck of the reflector, where the gas discharge lamp is arranged to be used as a holder for a separate igniter, and is locked with the igniter. Background technique [0002] Such headlamps are known per se and have a reflector with a reflector neck arranged to accommodate a gas discharge lamp and a clamping mechanism hinged on the reflector, said clamping mechanism being arranged to hold the gas The discharge lamp is clamped on the reflector neck, wherein the gas discharge lamp is provided as a holder for a separate igniter and is locked with the igniter. [0003] In the first known headlight, the fastening takes place by means of a rotatable integral ring. The EMV shielding (EMV: Electromagnetic Compatibility) is achieved by means of additional small c...
