Here a sample 3 watt led driver circuit diagram total 12 leds.
12 volt led driver circuit.
For operating an led with a 12v power supply or battery use minimum 560 ohms value resistor or you can also use 1k maximum value.
The future of lighting.
1n4732a or 1n4733a any lower and q2 won t be able to turn all the way on any higher and it won t work with most microcontrollers.

High power led driver circuits.
12 volt basic led circuit with 560 ohms resistor.
Right here we research a very easy 120v 220v smps led driver circuit that can be used for driving high watt leds rated any place between 1 watt to 12 watts instantly from any domestic ac mains outlet.
Use a 4 7 or 5 1 volt zener diode such as.
If your input voltage is below 10v switch r1 for a 22k ohm resistor the zener diode.
