A color mixing method for color fading and a color fading method using the method

摘要

The color-changing light emitting device includes at least first to third light sources and another light source, and the predetermined color mixture light is obtained by a relatively simpler method, so that the color of light emitted from the temporary light source is different from that of the first, The color mixing ratio is calculated as the light emission color of the remaining two or more light sources of the first to third light sources and the light emission color of the temporary light source, The color mixture ratio of each light source necessary for obtaining the color mixture light is obtained on the basis of the calculated color mixture ratio.
