Constant Current Bright LEDs

For most of my LED applications a very special circuit was designed to run the LEDs at a “constant current”.

Simple Constant Current Source

This simple constant current source uses an LM317 regulator IC. N.B. The pin-outs of the IC are not a mistake, the output is taken from the adjustment pin
