Abstract

A lighting control system (LCS) for generating supply currents for at least two LED channels (CH, CH, CHn) comprises at least two controlled current sources for generating a supply current for a corresponding LED channel based on a corresponding control signal. The system further comprises at least two signal combiners for generating the corresponding control signals based on a synchronization signal (VSYNC) that comprises periodic starting pulses and on a combination of a magnitude dimming signal and a pulse dimming signal corresponding to one of the LED channels. The signal combiners are designed such that changes of the respective control signals come into effect only with a respective time offset with respect to one of the starting pulses of the synchronization signal.
