Abstract
The invention relates to a method of controlling a lighting system with multiple controllable light sourcesand a system therefor. According to a first aspect, influence data of the lighting system are obtained, which data represent the effect of one or more of the light sourceson the illumination of one or more sections of an illuminated environment. In an optimization method, sets of control commands are continuously determined, a predicted light distribution for these control commands is determined from the influence data, and a colorimetric difference between the predicted light distribution and a target light distribution is determined. A plurality of adjustment steps are performed to minimize the colorimetric difference. According to a second aspect, a neural network is trained with the influence data and a set of control commands for controlling the lighting system is determined with the use of the neural network.
