Abstract
Method for generating light spectra and corresponding device. Starting from a plurality of light sources (), comprising the steps of selecting a target colour from a target region () of a colour space, and emitting a target light () from said light sources () according to a weighted combination of light sources () corresponding to said target colour, using an output model () which is optimized according to an optimization parameter, and previously determined in a modelling stage comprising: —calculating a plurality of mixed spectra (), as weighted combinations of said plurality of light sources (), their colour coordinates and their optimization parameters; —partitioning in sectors a modelling region () of said colour space; —for each sector, selecting the mixed spectrum having the best optimization parameter; thus obtaining an optimized weighted combination; —using the optimized weighted combinations, establishing a correspondence between colours and weighted combinations; —thus obtaining said output model ().
