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.
Part List Simple High Power LED Driver :
R1_____47 Ohm 1W
R2_____100 Ohm 1/2W
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.
