Driving LED by constant power mode has been a popular topic recently. Why do LEDs must be driven by the constant current? Why not with a constant power source? Before discussing the above issue, we have to understand why the LED must be driven by a constant current. As shown in Figure (a) LED I-V curve, when the LED forward voltage changed about 2.5%, the current through the LED will correspondingly change about 16%, and forward voltage of the LED is easily affected by junction temperature. The change of high and low temperature may even make the voltage chan...
