Document Type and Number:
WIPO Patent Application WO/2019/237757
Kind Code:
A1
Abstract:
A color correction method for a multi-color lamp comprises: collecting dot-matrix original light color parameters of multi-color lamps belonging to different batches or used at different times; and performing targeted acquisition of correction coefficient matrices of the respective multi-color lamps, and storing the same in color correction modules thereof. When in use, the color correction modules process source signals on the basis of the correction coefficient matrices of the respective multi-color lamps so as to control a drive circuit to drive light sources to emit light, thereby realizing standardized and consistent light colors, and enabling a user to perform dimming and color correction operations conveniently.
