| 摘要 |
The invention relates to an illumination device (100) comprising a plurality of LEDs (101a, 101b, 101c) emitting light in different source colors, the light of the illumination device being obtained by a combination of the source colors of the plurality of LEDs, an interface (111) adapted to receive an input signal (115) indicative of at least a color and/or brightness to be emitted by the illumination device, a storage unit (109) comprising colorimetric data indicative of colorimetric properties of the light emitted by the plurality of LEDs, wherein the colorimetric properties of the LEDs define the actual color gamut (205) of the illumination device; the storage unit further comprising predefined color gamut (207) data indicative of a predefined color gamut, and a processing unit (107) adapted to generate an activation signal for the plurality of LEDs (101a, 101b, 101c) based on the input signal (115), wherein the processing unit (107) is adapted to generate an adjusted color gamut (209) based on the actual color gamut (205) and based on the predefined color gamut (207), wherein the processing unit is adapted to generate the activation signal for the plurality of LEDs based on the input signal and based on the adjusted color gamut. |
