Why use pwm dimming?

There are actually many LED dimming driver methods, which can be simply divided into digital dimming and analog dimming. PWM dimming belongs to digital dimming, which controls the brightness of the lamp by turning on and off the square wave to change the conduction time of the forward current. It can be seen that the dimming principle of analog dimming and pwm dimming power supply is completely di...

What is PFC and what does it do?

Power factor correction is abbreviated as PFC, which is mainly to improve the ratio of effective power to apparent power at the input end of a power supply. It is one of the common circuits in led dimmable power supplies. Generally, the power factor of the input end of the model without PFC circuit is only 0.4~0.6, but with active PFC circuit, it can reach more than 0.95 Active power factor correc...

Why should LED be driven with constant current?

First, the output current of the dimmable constant current led driver is constant, and the output voltage changes with the VF value of the LED. This is in line with the characteristics of the LED and keeps the luminous brightness constant. The LED is greatly affected by the current change, and the constant current drive can be extended The life of the LED; in addition, the luminous efficiency and ...
