Due to the limitation of LED power level, the driving circuit usually needs to drive multiple leds at the same time to meet the brightness requirements. Therefore, a special driving circuit is needed to light the LED. Resistance capacity step-down, using the impedance of capacitor in ac to limit the input current, dc level to power LED.
