Abstract (en)
[origin: EP2375870A2] The method involves determining actual color location of al illumination in a region to be illuminated. Intensity and chromaticity of light emitted from a light sources (107, 108, 109) e.g. LEDs, is determined. Impact of natural daylight is calculated, and a control value for the light sources is calculated and transmitted, where the control value produces an illumination with a color temperature with mixing of the light emitted from the light sources with a daylight and corresponds to the predetermined target value and the LED emits light in different colors such as red, green and blue.
