low cost precision light control dimmer


Posted on Feb 5, 2014

Using a the controlled-half-plus-fixed-half-wave phase control method, this circuit can regulate an 860 a watt lamp load from half to full power. This circuit control the light output of the lamp from 30% to 100% because Half power applied to an incandescent lamp gives 30% of full light output. This is the figure of the circuit;
