| description | The invention provides a light mixing method used for LED light sources. The light mixing method comprises the following steps that A. the white balance brightness ratio alpha: beta: gamma of corresponding three primary colors RGB of the LED light sources corresponding to expected color temperature is calculated according to the expected color temperature; B. the maximum brightness values LRmax, LGmax and LBmax of the corresponding three primary colors RGB of the LED light sources under the maximum current Imax are acquired; C. the expected brightness values LR, LG and LB of the corresponding three primary colors RGB of the LED light sources are calculated according to LRmax, LGmax and LBmax and the white balance brightness ratio alpha: beta: gamma; D. the expected colors of the LED light sources and the corresponding color coordinates (a, b, c) of the expected colors are acquired; E. the duty ratio DR, DG and DB of the corresponding three primary colors RGB are calculated according to the color coordinates ( |
