14+ Led Dimmer Circuit Diagram. This is a very simple led dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. In this circuit we have used 10 super bright white leds, but the number of leds can be increase if desired.
I chose the value 120 ohm in order to get a current of about 30ma (current passes through. 555 timer ic a widely used one was used to generate the pwm signal here. Led lamps, garlands, tapes are very popular today.
The ac supply is applied to the load for only a controlled fraction of each cycle.
14+ Led Dimmer Circuit Diagram. Capacitor c4 is charged via resistors r3, r4, p1, and r5. This is a very simple led dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. There's two common ways that leds are dimmed: Find this pin and more on pinned electronic circuits by matthew yorke.
