Calibrated Led By LM334

Advertisements

Here is Calibrated Led Circuit. It Use IC LM334 (3-Terminal Adjustable Current Source) For Display Led Current. By current that flow through LED control with the value R.
Such as
R = 10 OHM : I LED =6.4mA
R = 15 OHM : ILED = 4.3mA
In order that you can use Volt supply 3V-20V and it uses current low stable economize the electric energy well.
