Accompanying drawing explanation

Fig. 1 is the circuit diagram of energy-saving long-life LED illumination circuit。

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。

Refer to Fig. 1, a kind of energy-saving long-life LED illumination circuit, including key switch S1, relay K 1, audion V1 and rectifier bridge T, one end of described key switch S1 connects contact K1-1 and the 220V alternating current of relay K, the winding N1 of the other end connection transformer W of key switch S1, the other end of the winding N1 of transformator W connects the other end of 220V alternating current, one end of the winding N2 of transformator W connects port 1 and the transient voltage suppressor diode DW of rectifier bridge T, the other end of the winding N2 of transformator W connects the port 3 of rectifier bridge T and the other end of transient voltage suppressor diode DW, the port 2 of rectifier bridge T connects resistance R1, resistance R2, electric capacity C2, the contact K2-1 of relay K 2 and relay K 2, the other end of electric capacity C2 connects electric capacity C1, relay K 1, the emitter stage of audion V1, the port 4 of rectifier bridge T, the fixing end of of potentiometer RP1, the sliding end of potentiometer RP1 and LED lamp H, the other end of resistance R1 connects the other end of relay K 1, the colelctor electrode of the other end connecting triode V1 of relay K 2 and the base stage of audion V2, the base stage of audion V1 connects the other end of electric capacity C1, the colelctor electrode of audion V2, the other end of resistance R2, the emitter stage of audion V2 and another fixing end of potentiometer RP1, the other end of the contact K2-1 of relay K 2 connects the other end of LED lamp H。
