Accompanying drawing explanation
Fig. 1 is the circuit diagram of LED emergency light control circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of LED emergency light control circuit, comprise triode V1, triode V2, rectifier bridge T and resistance R1, one end of described resistance R1 connects electric capacity C1 and 220V alternating current, the other end of resistance R1 connects the other end of electric capacity C1, the port one of transient voltage suppressor diode DW and rectifier bridge T, the port 3 of rectifier bridge T connects the other end of transient voltage suppressor diode DW and the other end of 220V alternating current, the port 2 of rectifier bridge T connects electric capacity C3, resistance R2, the anode of diode D3 and the anode of diode D4, the other end contact resistance R3 of resistance R2, the negative electrode of diode D2 and the base stage of triode V1, the port 4 of rectifier bridge T connects electric capacity C2, the other end of electric capacity C3, the other end of resistance R3, the emitter of triode V1, the emitter of triode V3 and storage battery E, the collector electrode of triode V1 connects the other end and the resistance R4 of electric capacity C2, the other end contact resistance R5 of resistance R4, the negative electrode of diode D3 and the base stage of triode V2, the other end of resistance R5 connects the negative electrode of diode D1 and the emitter of triode V2, the collector electrode contact resistance R6 of triode V2 and resistance R7, the other end of resistance R6 connects the anode of diode D2, the base stage of the other end connecting triode V3 of resistance R7, the collector electrode of triode V3 connects LED group H, the negative electrode of diode D4 connects the anode of diode D1, the other end of the lamp group H such as the positive pole of storage battery E and LED.
