And 102, when the color control mode is a color temperature mode, calculating the color temperature and color mixing ratio of the cold white light lamp and the warm white light lamp according to the color temperature value in the color parameter.
Optionally, this step may include: calculating a standard color temperature parameter according to the color temperature value in the color parameter; and calculating the color temperature and color mixing ratio of the cold white light lamp and the warm white light lamp according to the standard color temperature parameter.
