    • A method for operating an LED lighting device (L), wherein the LED lighting device comprises: at least two color channels (Ch1, Ch2, Ch3), wherein each color channel (Ch1, Ch2, Ch3) comprises at least one LED (LD1, LD2, LD3), wherein the LEDs (LD1, LD2, LD3) of a color channel (Ch1, Ch2, Ch3) each have the same color, and wherein each color channel (Ch1, Ch2, Ch3) is able to be activated separately, and at least one photodetector (D), which is configured and arranged to detect a portion of the light radiated by the LEDs (LD1, LD2, LD3), wherein the method comprises the steps of: switching over the LED lighting device (L) from an operating phase (BP 1) into a measurement phase (MP); and temporally consecutive activation of the color channels (Ch1, Ch2, Ch3) so that a light radiated during the measurement phase (MP) by the LEDs (LD1, LD2, LD3) has an integral mixture which substantially corresponds to a color mixture of the operating phase.
    • 一种用于操作LED照明装置(L)的方法,其中所述LED照明装置包括:至少两个颜色通道(Ch1,Ch2,Ch3),其中每个颜色通道(Ch1,Ch2,Ch3)包括至少一个LED(LD1 ,LD2,LD3),其中颜色通道(Ch1,Ch2,Ch3)的LED(LD1,LD2,LD3)各自具有相同的颜色,并且其中每个颜色通道(Ch1,Ch2,Ch3)能够被激活 以及至少一个光电检测器(D),其被配置和布置成检测由所述LED(LD1,LD2,LD3)辐射的光的一部分,其中所述方法包括以下步骤:切换所述LED照明装置 L)从操作阶段(BP 1)进入测量阶段(MP); 并且在时间上连续地激活彩色通道(Ch1,Ch2,Ch3),使得在LED(LD1,LD2,LD3)的测量阶段(MP)期间辐射的光具有基本对应于 操作阶段
