12 Watt Led Bulb Driver Circuit Diagram

The driver circuit divides a string of 25 leds into two sets of five one set of four and one set of six.

12 watt led bulb driver circuit diagram. The input mains 220v or 120v ac is half wave repaired by d1 and c1. The above circuit is designed to drive a led with 0 2a. The main component is the x rated ac capacitor which can reduce the supply current to a suitable amount. 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. 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. This current rating is fixed by the resistor r1 in the circuit. In this we designed an led light bulb and used it as a regular bulb.

C1 together with the inductor l0 and c2 make up a pie filter network for cacelling emi disturbenaces. So below i m writing an article on making of a high power led driver circuit. The circuit diagram of the high power led driver is shown in the image below. These capacitors are connected line to line and are designed for high voltage ac circuits.

Hopefully you are able to find a driver that can accomplish your led circuit with the diodes in series however there are circumstances that might make it impossible. Led downlights 4 slim recessed light 6 slim recessed light 8 slim recessed light led flood lights 10 watt 20 watt 30 watt. 12 volt led light strips. Circuit diagram and explanation.

I got many requests to provide guide to build simple 230v to 1 3 5 watt led driver in response to my simple led driver diagram. Another interesting led circuit is the diy led light bulb. As you can see the driver has nothing more than a lm317 ic and a resistor. 1 small 1 watt smps led driver.

The circuit working of this 1 watt to 12watt led driver may be known as presented under. It can be directly driven from any domestic 220v ac or 120v ac mains outlets. It is very dangerous to use 230v ac supply on breadboard. In the first design which is the most recommended one we study an smps led driver circuit which can be used for driving high watt leds rated anywhere between 1 watt led upto 12 watts.

The below device is able to run upto 5watt leds from the led supply line and 18watts of 12v led strips. 230v led driver circuit principle. The formulae to determine the current is. Sir is this circuit suitable for 9 watt and 12 watt as i want to use 9 parallel led of 1 2 watt and want to operate circuit at for 12 volt battery source led spec is 9 10 voff and 120 ma current please tell me what change is exaxtky required and lm 338 required heat sink or suggest any other good ckt for different combination like strings of 4 led 3 volt voff and 3 parallel series of this.
