Abstract
A method for supplying power to a plurality of light generators (CH1, CH2, CH3) which emit respective chromatically different light radiations that can be mixed with one another to produce a mixed light radiation by selectively activating said generators with respective supply powers (P1, P2, P3) over respective activation intervals (T1, T2, T3) included in an activation period (T), provides for: identifying (102) at least one pair of generators (CH1, CH2; CH2, CH3) for which the sum of the respective activation intervals (T1, T2; T2, T3) is less than said activation period (T), and temporally offsetting the activation (106) of the generators (CH1, CH2; CH2, CH3) in the one pair, avoiding simultaneous activation.
