Abstract (en)
[origin: WO2010122013A1] The invention relates to a method and a lighting system designed therefor for controlling a multichannel LED module (3), wherein the light radiated by the multichannel LED module (3) is set to a predetermined color by independently activating the individual channels (5) and the actually radiated light color (11) is fed back for control purposes. A rough control, in which only the channels of a subgroup, in particular two channels, are adjusted independently of each other, occurs in a first step until the overall radiated light color lies within a specified tolerance range. A fine control, in which all channels are adjusted, occurs in a second step.
