ILLUMINATION DEVICE FOR A MOTOR VEHICLE AND CONVERSION LAYER FOR USE IN SAID TYPE OF ILLUMINATION DEVICE

摘要

The invention relates to an illumination device for a motor vehicle, comprising a light source (2) consisting of a number of semiconductor diodes which generate light in a first predetermined wavelength range, and a conversion layer (5) on which a light bundle (L) generated from the light of the light source (2) falls and by which the light bundle (L) is changed into a converted light bundle, in which the light of the light bundle (L) is converted into a second predetermined wave length range by a converting material. Said illumination device (1) is designed in such a manner that a predetermined light distribution from the converted light bundle is generated at a distance from the illumination device (1). The claimed illumination device is characterized in that a structure (501) having one or more walls with a predetermined depth in the direction of the thickness of the conversion layer (5) is provided in at least one partial region of the surface of the conversion layer (5).
