What is flicker free led driver

Flicker free led driver means that there is no flicker due to frequency problems. In the LED lighting industry, flicker free led driver means that the AC components in the power output are filtered through filter circuit, bipolar power supply scheme, de ripple circuit, valley filling circuit and other relevant circuits.

In fact, ripple current is the main cause of power supply stroboscopic. If LED lamps want to achieve no stroboscopic, we need to start mainly from LED power supply.
