Design of Wireless Remote Control System for Domestic Lamps

摘要

Silicon-controlled PM principle is commonly used in most home light-dimmer system. The conducting time of the controllable silicon is changed by controlling the time constant RC, so as to change the effective voltage, and then to realize the light control. However, this kind of circuit is confined to manual control, and difficult to remote control. The commonly light-dimmer lamp is such an example. If we want to remote control the on-off and its brightness, the silicon-controlled circuit with RC structures discussed above must be replaced by PWM voltage circuit. A stepless voltage-adjusted remote system is proposed in this paper, it can be economically used in family lamp and other appliances.
