Abstract (en)
[origin: WO2011098334A1] The invention relates to a method serving to operate an LED lighting device (L), wherein the LED lighting device (L) has at least: at least two color channels (Ch1, Ch2, Ch3), in particular of different colors, wherein each color channel (Ch1, Ch2, Ch3) comprises at least one LED (LD1, LD2, LD3) of the same color and wherein each color channel (Ch1, Ch2, Ch3) can be actuated separately, and at least one photo detector (D), which is configured and arranged to detect a portion of light radiated from the LEDs (LD1, LD2, LD3), wherein the method comprises at least the following steps: changing the LED lighting device (L) from an operating phase (BP1) to a measurement phase (MP); and temporally successively actuating the color channels (Ch1, Ch2, Ch3) so that light radiated during the measurement phase (MP) by the LEDs (LD1, LD2, LD3) has an integral color mixture which substantially corresponds to a color mixture of the operating phase (BP1).
