A motor vehicle headlight assembly includes a reflector extending along a focal line and having an open end, a light source including an elongated gas discharge tube extending within the reflector along the focal line for the light issued thereby onto the reflector to be reflected by the latter into the open end, and an at least translucent light-guiding plate spanning the open end of the reflector and operative for directing light passing through it onto an illumination area situated at a predetermined distance in front of the motor vehicle on which the headlight assembly is mounted when in use. The reflector has at least in general the configuration of a flattened cross-sectionally parabolic cylinder and consists at least in part of two opposing regions at least one of which is inclined by a predetermined angle about the focal line with respect to the position it would have assumed in a true cross-sectionally parabolic cylinder.

Headlight assembly with angularly displaced reflector regions

An illumination device for a vehicle has a light source, a reflector which reflects a light emitted by the light source so that the reflected light exits the illumination device in a first light outlet direction, the reflector being interrupted at least in one region, and at least partial light-permeable element arranged in the region and formed so that the light emitted by the light source passes through the light-permeable element and exits the illumination device in a second light outlet direction which deviates from the first light outlet direction.

Illumination device for vehicle

A headlight for vehicles has a light source, a reflector having at least two different reflector regions including a first reflector region which reflects a light emitted by the light source as a converging light beam to form low beam and a second reflector region formed so that light emitted by the light source and reflected by the second reflector region together with the light emitted by the light source and reflected by the first reflector region form high beam, a lens arranged after the reflector in a light outlet direction so that at least the light which forms low beam passes through the lens, and a screening device arranged between the reflector and the lens, the screening device having a stationary screening part and a movable screening part, the movable screening part being movable between a position for low beam in which light forming low beam can pass along the movable screening part and a position for high beam in which additionally the light reflected by the second reflector region can pass along the movable screening part at least partially, so that in the position for low beam an edge of the screening device forms a bright-dark limit of low beam, the screening parts each having a plurality of openings formed so that in the position of the movable screening part for low beam the movable screening part covers the openings of the stationary screening part, and in the position for high beam the openings of the movable screening part coincide with the openings of the stationary screening part at least approximately so that the screening device forms throughgoing openings for the light.

Headlight for vehicle

The headlamp having a housing in which a reflector is arranged adjustably and the light exit opening of which is covered by a covering plate. In the region of the light exit opening of the housing there is arranged a covering device which has a fastening portion held in the housing and an edge portion which projects from said fastening portion counter to the light exit direction. Formed between the edge portion and the fastening portion is a clearance into which the front edge of the reflector projects, a distance which is required for the adjustment of said reflector being maintained from these parts. From outside the housing, when looking through the covering plate, no gap is visible between the front edge of the reflector and the inside of the housing.
