Patent ID: 8115416

Claim:
A method for generating mixed light colors from an individually pulse-time-controllable energization of light sources ( 11 ) for colors having brightness which are influenceable by varying periodically successive duty ratios of a current flowing via the respective light source ( 11 ), wherein apart from a constant current intensity of a regular energization, at least one lower constant current intensity is made available for the light sources and the current intensity of the current flowing via one of the light sources ( 11 ), with a simultaneous lengthening of the current flow time span within the period (P), is reduced to said at least one lower constant current intensity, wherein an arising total current-time integral corresponds to a current-time integral of the duty ratio predetermined for the period, and a current-dependent drift of a color locus of the light of this light source ( 11 ) is compensated for by a changed driving of different-colored light sources.
