-TRIAC Light Dimmer

本文引用地址:http://www.eepw.com.cn/article/163274.htm

This little circuit can be used to dim lights up to about 350 watts. It uses a simple, standard TRIAC circuit that, in my expirience, generates very little heat. Please note that this circuit cannot be used with fluorescent lights.
