Abstract

A variable color lighting arrangement includes at least first to third light sources and at least one other light source, and allows a desired mixed color light to be obtained in a relatively simpler manner, such that an emission color of an assumed light source is first set with an emission color of one of the first to third light sources mixed with another emission color of the other light source, a mixing ratio is calculated with emission colors of remaining two or more of the plurality of light sources including at least the first to third light sources and the emission color of the assumed source, and a required mixing ratio of the respective light sources for obtaining the desired mixed color light is obtained on the basis of the calculated mixing ratio.
