Abstract
A method, an apparatus and a system for controlling a light source are disclosed. The method comprises: receiving a dimming command, determining the dimming item specified by the dimming command (201); determining the corresponding chopping type and/or the range of the chopping phase angle according to the dimming item (202); and controlling the regulation switch according to the determined chopping type and/or the range of the chopping phase angle in order to output the voltage containing a chopping voltage (203). The method, the apparatus and the system can achieve the regulation functions for the light source color and/or the luminance etc.
Claims19
