An active constant current source is commonly used for high power LEDs, stabilizing light output over a wide range of input voltages which might increase the useful life of batteries. Active constant current is typically regulated using a depletion-mode MOSFET (metal–oxide–semiconductor field-effect transistor), which is the simplest current limiter. Low drop-out (LDO) constant current regul…

NettetTesting an LED. Never connect an LED directly to a battery or power supply because the LED is likely to be destroyed by excessive current passing through it.. LEDs must have a resistor in series to limit the current to a safe value, for testing purposes a 1k resistor is suitable for most LEDs if your supply voltage is 12V or less. Remember to connect the … NettetDriving LEDs with constant current ensures safe operation with maximum possible light output.
