Illumination Device for a Motor Vehicle
First Claim
1. An illumination device for a motor vehicle, comprising:
- a light source constructed of a number of semiconductor diodes;
a scanner onto which a light beam generated by light of the light source falls, the scanner changing position of the light beam during operation of the illumination device to move a light spot generated by the light beam at a distance from the illumination device, wherein a predetermined light distribution is generated by the moved light spot; and
a beam-delimiting device arranged between the light source and the scanner, the beam-delimiting device delimiting a cross section of the light beam along a predetermined boundary, wherein one or more light-dark boundaries are formed in the predetermined light distribution by at least one segment of the predetermined boundary.

Abstract
An illumination device is provided for a motor vehicle, including a light source consisting of a number of semiconductor diodes, and a scanner onto which a light beam produced by 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 generated 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 characterized in that a beam delimiting device, which allows the cross-section of the light beam to be delimited along a predetermined boundary, is provided between the light source and the scanner. The illumination device is designed in such a way that one or more light-shadow lines can be formed in the predetermined light distribution by way of at least one section of the predetermined boundary.
