This is a very simple guide on how to make a driver for a high power 3w led. with changing the resistor, you can connect up to ten high power LEDs to this circuit. All u need is
- 1 LM317 regulator
- 1 1,8 ohms resistor (1watt), if u are using only one 3w led
- some wire
The LM317 regulator gives out a constant voltage of 1,25 volts between ADJ and Vout.
In Deutschland sind Konstantstromquellen für high power LEDs hier erhältlich!
from left to right: resistor, regulator, 3w high power led, wire
solder wire to the cathode and anode of the 3w high power led:
the red wire has to be connected to minus of pole of the power source (on the next pic the red wire is changed to black), the black wire to the cathode of the led. The resistor connects to the regulator and the black wire;
it's working!!!
Thanks for introducing with 3w LED driver. The photos you have shared those very helpful know about 3w LED driver.
AntwortenLöschenLED light is also a high power light because it is giving much brightness by using little voltage.
