Abstract (en)
[origin: WO2014067830A1] The invention proposes a circuit (2) for controlling a plurality of LED channels (K1, K2) each having at least one LED (L1, L2) and for generating mixed light from the light generated by the respective LED channels (K1, K2), wherein a look-up table is provided in each case for each target colour locus which can be reached by the LED module, said table storing the operating current (Ir, Iw) for each LED channel (K1, K2).
