    • The present invention relates to a method of controlling the output of a luminaire comprising an array of LEDs emitting light of at least one color. The array comprises single color LED groups, each consisting of at least one LED. The method comprises the following steps for each LED group: - spectrally bandpass filtering the light emitted by the LED group by means of a filter device, wherein a filter characteristic of said filter device has a peak; detecting the spectrally filtered light from said filter device and generating a response signal, wherein the level of said response signal is related to an amount of detected spectrally filtered light; and - controlling the light output of said LED group at least partially on the basis of said response signal, comprising maximizing the level of said response signal by spectrally shifting the spectrum of the light emitted by the LED group and said filter characteristic in relation to each other. A control system for performing the method is also provided.
    • 本发明涉及一种控制照明器的输出的方法,该照明器包括发射至少一种颜色的光的LED阵列。 该阵列包括单色LED组,每个LED组由至少一个LED组成。 该方法对于每个LED组包括以下步骤: - 借助滤波器装置对由LED组发射的光进行频谱带通滤波,其中所述滤波器装置的滤波器特性具有峰值; 检测来自所述滤波器装置的光谱过滤光并产生响应信号,其中所述响应信号的电平与检测到的光谱过滤光的量有关; 以及 - 至少部分地基于所述响应信号来控制所述LED组的光输出,包括通过对由LED组发射的光的光谱和所述滤波器特性相对于每个光谱的频谱进行光谱移位来最大化所述响应信号的电平 其他。 还提供了用于执行该方法的控制系统。
