可控硅調(diào)光燈電路-TRIAC Light Dimmer
本文引用地址：http://m.ptau.cn/article/163274.htmThis 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.
