C1, R1, RV1, L1 and R2 constitute the first level power R2 filter circuit, which is used to the input transient momentary high voltage filter.C2, R3 constitutes step-down circuit, C3, C4, L2 and RV2 use rectifying filter circuit.This circuit is double filter circuit and can effectively protect LED from being broken down momentary high voltage.
