Embodiment Construction

[0053] figure 1 A perspective view of a blinding device 1 is shown, such as a blinding device for headlights in a motor vehicle. The shade device 1 is installed in the reflector of the headlight and serves to shade a part of the light beam emitted by the light source accommodated in the reflector. The visor device 1 firstly comprises a base part which is formed by the carrier 22 and via which the visor device 1 is mounted in a reflector or a light module of a headlight of a motor vehicle. The shutter device 1 has a shutter 2 which has a plurality of component parts. The main component of the visor 2 is the visor arm 9 , which extends parallel to the carrier 22 and blocks the beam of light in the direction of light emission, which corresponds to the difference between the low beam and the high beam of the headlight. According to this view, the visor arm 9 is shown in the low beam position, since the visor arm 9 extends on the carrier 22 and rests against the visor arm stop 23...

Abstract

The present invention relates to a headlight for a motor vehicle having a light source, which is arranged in a reflector, for emission of light beams in a light outlet direction, having a masking apparatus (1) which has a mask (2) which can be moved to a first position in order to mask out at least a portion of the light beams, and which can be moved to a second position in which the mask (2) is moved at least partially out of the light beams, wherein the movement of the mask (2) can be produced by an actuator unit (3) which has at least one magnet coil (4) and a magnet yoke (5) in order to form a magnetic flux circuit. According to the invention, a hinged armature (6) is provided, is held in an articulated manner on at least a part of the magnet yoke (5) and is in the form of part of themask (2), such that the hinged armature (6) carries out a folding movement, and produces the movement of the mask (2), when current is passed through the magnet coil (4).

Description

technical field [0001] The invention relates to a headlight for a motor vehicle, having a light source arranged in a reflector for emitting a light beam in a light emission direction. The headlamp has a visor with a visor that is movable into a first position, which may constitute a low beam position, for at least part of the light beam is blocked, and is movable into A second position, which can constitute a high beam position, in which the visor is at least partially moved out of the light beam, wherein the movement of the visor can be produced by means of an actuator unit having at least one Magnetic coils and a yoke for forming a magnetic flux circuit. Background technique [0002] A headlight for a motor vehicle is known from DE 199 33 415 A1, which has a light source arranged in a reflector for emitting a light beam in the direction of light emission. The headlamp has a visor with a visor movable between a first position and a second position. The movement of the vi...
