  • Patent number: 9827900
    Abstract: A method is provided for operating a headlight having a laser light source in a motor vehicle. The headlight generates a light distribution from the light of the laser light source. The laser light source is activated such that the operating power of the laser light source is switched from a first power value to a deactivated operating state or is lowered to a second power value when the speed of the motor vehicle falls below a first speed threshold. The operating power of the laser light source is increased from the deactivated operating state or from the second power value to the first power value, when the speed of the motor vehicle exceeds a second speed threshold, which is greater than or equal to the first speed threshold.

  • Patent number: 9752745
    Abstract: An illumination device for a motor vehicle includes a light source consisting of a number of semiconductor diodes, and a scanner onto which a light beam obtained from light of the light source falls and which modifies the position of the light beam during operation of the illumination device and thereby moves a light spot produced by the light beam at a distance from the illumination device. The moved light spot allows a predetermined light distribution to be generated. The illumination device is designed such that the scanning speed at which the light spot is moved, the scanning path along which the light spot is moved, and/or the size of the light spot can be varied and is/are controlled to generate the predetermined light distribution.
