发明名称 Color adjustable lamp
摘要 A color adjustable lamp may be controlled using a TRIAC dimmer circuit and includes a lamp driving circuit and two or more light sources. Each light source may output light having a different color. By setting an output intensity of each light source, light having a desired color may be output. A circuit or a processing unit of the lamp driving circuit may detect a set phase angle of the TRIAC dimmer circuit by determining a shape of the supplied alternating voltage. According to the determined shape, the circuit or processing unit controls a lamp driver circuit for each light source in order to control the intensity of the light output by each light source and set the color of the color adjustable lamp by adjusting the intensity of the light emitted by each light source.
