Abstract:
An LED lighting drive circuit supplies power for N groups of LED loads. The LED lighting drive circuit comprises N current paths, N groups of LEDs, and a constant current section. The LED lighting drive circuit enables the current of LED lamps to change in a sinusoidal half-wave form with the utility AC input, and keeps the current a constant effective value.
