Abstract
Official abstract text for this publication.
The invention relates to a method for calibrating a lighting apparatus, particularly lighting apparatus for a motor vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for calibrating a lighting apparatus, the method comprising: providing a lighting apparatus having a plurality of illuminants and a control means for individually controlling the settings of each illuminant of the plurality of illuminants, producing or projecting at least one pattern of light distribution from at least one selected illuminant of the plurality of illuminants having an individual light distribution, wherein said individual light distribution is overlap-free, using a sensor to detect the pattern of light distribution, determining at least one characteristic of each of the individual light distributions of the at least one selected illuminant, calibrating the lighting apparatus on the basis of a comparison of the at least one pattern of light distribution with a predefined setpoint data. 2. The method according to claim 1 , wherein the calibrating involves multiple illuminants producing or projecting a first and a second pattern from the individual light distribution of each of the multiple illuminants, in which the individual light distributions at least essentially do not overlap. 3. The method according to claim 2 , wherein the second pattern is a complementary pattern for the first pattern. 4. The method according to claim 2 , wherein a change between the first pattern and the second pattern and vice versa is effected at a prescribable frequency. 5. The method according to claim 2 , wherein the first pattern and/or the second pattern is a regular pattern. 6. A control apparatus, such as a controller, for carrying out the method according to claim 1 .
