Constant current infrared LED emitter circuit [Project]
posted December 18 2013 10:45.11 by spic0m




The crew from AnalysIR reports they have written up an article on constant current circuit for Infrared LEDs. They compare the various methods of driving IR LEDs, including a series resistor and a circuit driven by an NPN transistor, and how to design your circuit for maximum brightness.
