Constant LED Power Supply Wiring diagram Schematic
An LED is usually a series resistor needed to ensure that the LED does not get too much power. The disadvantage of such a resistor is that the current thus also changes by the LED and the brightness as the voltage changes.
This schema prevents that, by independent of the voltage, a constant current through the LED.The schema uses two transistors and two resistors. The schema can be connected to voltages of from 5 to 24 V.
