Light Dimmer Circuit Using Triac And Diac. The circuit of light operated lamp switch utilizes a diac and a triac as semiconductor and ldr as sensor. Diacs are mainly used in dimmer applications and also in starter circuits for florescent lamps.
Which controls the speed of charging of c1. The diac conducts a break over voltage. A light dimmer circuit is perhaps the most popular application using a triac diac combination.
The power operated components diac and triac are used for controlling the output power with some other electronics parts like resistor capacitors and potentiometer.
Ac light dimmer circuit using triac and diac update from the previous circuit operation of the circuit. Some time we required to control the power of incandescent lamps. Here in this circuit the light illumination is controlled using triac and diac. At dark its resistance increases up to mega ohms which does not exit triac and.
