This saturates q1 avoiding a further increase in current to the led. Constant current led driver circuit. As the name suggests the constant current driver will supply the same current whatever voltage it is supplied with and whatever the forward voltage of the led.
This is a fet constant current drivers circuit for drive led display which can use fet bf256 instead resistor so well.
Design of constant current driver. Normally when you use led display in any circuits often use a resistor for limit led current. The current values depending on voltage for a normal red led. Design of constant current driver.
