Simple 10W High Power LED Driver Circuit

This is my project for handmade flashlight when using 10W High Power LED voltage 12V DC. Indeed, by using this LED light produced is very bright. However, to use this LED requires a power of 10W and 12V stabilized voltage, so that LEDs are more durable long lasting without reducing the productivity of the light produced High Power LED's.

So it takes a LED driver circuit, precisely to control the voltage current and voltage itself. Here ne driver circuit is simple and easy to manufacture only need a few components that are easy to find in stores store and the price is very affordable. It also can use recycled components from the junk PSU.

Simple 10W High Power LED Driver Circuit

Part List Simple High Power LED Driver :
R1_____47 Ohm 1W
R2_____100 Ohm 1/2W
C1_____2200uF /16V
Q1_____NPN Transistor can using ( TIP3055, TIP31,D882)
T1_____A coil obtained from PSU Computer
LED1__10 Watt High Power LED / 12V
Source_ 12 Volt DC can use 12V Car Battery

For Installation, Install transistor with cooling, as well as its LED. See Tested Simple High Power LED Driver Video :

Note : Be careful with lights up current High Power LED, because LEDs also produce heat at the bottom, so do not touch it. Also On the LED front, not to knock, because it can damage the LED.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


does this limit the current?or is voltage controlled?

and what is the vallue of the coil T1?

the value of t1 is 10uH , you can use from junk psu unit.

What if you wanted a 20w led? What would you have to change?

you can add more transistor for driving the 20W High Power Led

How many turn is required for T1 in the circiut.Can it be obtaine from led driver circuit i.e.ferrite toroid coil

is about 20 turn, you can use from a junk psu computer.

Okay so i add another one? Not sure I understand.

What is the output current(I) in the circuit

it const current output about can drive the leds.. 1.A output we have
