Light Dimmer Schematic Diagram. It uses a simple standard triac circuit that in my expirience generates very little heat. This simple 220v light dimmer circuit can be used to adjust the brightness of mains lights.
Assemble the circuit on a good quality pcb or common board. It uses a triac diac and has a radio frequency interference rfi noise suppression circuit built into it as well. This little circuit can be used to dim lights up to about 350 watts.
One is an n channel mosfet and a potentiometer.
The circuit is based on the principle of power control using a triac the circuit and design are the same for fan or light the only difference is the output load to be varied that is fan or light. This simple 220v light dimmer circuit can be used to adjust the brightness of mains lights. By making slight modification with respect to the power dissipation you can even implement this circuit with high power leds for real time use. The circuit is based on the principle of power control using a triac the circuit and design are the same for fan or light the only difference is the output load to be varied that is fan or light.
