9 Watt Led Bulb Driver Circuit Diagram. The main component is the x rated ac capacitor which can reduce the supply current to a suitable amount. The reference circuit for the microchip cl8800 is close to the circuit found on the 3m led bulb though the 3m bulb includes an additional rc network not shown here for phase dimming.
So which part of the circuit is to be modified. This inverter driver provides power for leds like white blue uv but also any other from 3 7v single cell battery. The circuit working of this 1 watt to 12watt led driver may be known as presented under.
The basic principle behind the 230v led driver circuit is transformer less power supply.
Led current in amps 1 25 r3 so for a current of 550ma set r3 to 2 2 ohms you ll need a power resistor usually r3 power in watts 1 56 r3 this circuit also has the drawback that the only way to use it with a micro controller or pwm is to turn the entire thing on and off with a power fet. And the only way to change the.

In this circuit we will drive an led directly from 230v ac mains supply.
