  • Publication number: 20120092884
    Abstract: A projection headlight for motor vehicles has a reflector device, a plurality of light sources, at least one of said light sources assigned to the reflector device. A lens device is arranged in front of the reflector device in the main radiation direction. A cover device in the area of a focal point of the lens device has a cover shaft rotatable across the main radiation direction of the rotating axis main source. The cover shaft is provided with a number of glare edges and/or glare surfaces to adjust light distributors having a number of various cut-off lines. The light sources are arranged on a common light source carrier, the carrier extending substantially perpendicular to the main radiation direction and the carrier being configured to fasten onto a flat side of a heat sink.
