Simple basic led circuit.
12 volt led driver circuit.
In the present circuit the maximum voltage available is 12 dividing 12 by 3 4 meaning 4 numbers of leds can be accommodated at this voltage and yet we are able to limit the power to 0 06 watts.
Use a 4 7 or 5 1 volt zener diode such as.
Here a sample 3 watt led driver circuit diagram total 12 leds.

High power led driver circuits.
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.
1w to 5w led driver circuit with 12v input this led driver circuit explains how you can power up 0 5w to 5w led strips directly from a 12v lead acid battery without wasting much power or blowing up the leds.
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.
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.
