Abstract:
1. A light source mixture control device for controlling a light source emitting different spectrums to independently control a hue and a luminance, the light source mixture control device comprising: a coordination conversion unit for receiving and converting a hue signal and a luminance signal into a first, a second and a third undecoupled color light component; a first color light component decoupling control unit, coupled to the coordination conversion unit, for decoupling a first color light component from the first to the third undecoupled color light component; a second color light component decoupling control unit, coupled to the coordination conversion unit and the first color light component decoupling control unit, for decoupling the first undecoupled color light component into a first decoupled color light component according to the first color light component; a third color light component decoupling control unit, coupled to the coordination conversion unit and the first color light component decoupling control unit, for decoupling the second undecoupled color light component into a second decoupled color light component according to the first color light component; and a fourth color light component decoupling control unit, coupled to the coordination conversion unit and the first color light component decoupling control unit, for decoupling the third undecoupled color light component into a third decoupled color light component according to the first color light component, wherein the first to the third decoupled color light component respectively and independently control the light source.
