Accompanying drawing explanation
Fig. 1 is the circuit diagram of LED emergency light DC power-supply system.
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 are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1,In this utility model embodiment,A kind of LED emergency light DC power-supply system,Including transformator W、Rectifier bridge T1、Chip IC 1 and potentiometer RP1,The two ends of the winding N1 of described transformator W connect 220V alternating current respectively,One end of the winding N2 of transformator W connects port 1 and the port 1 of rectifier bridge T2 of rectifier bridge T1,The port 2 of rectifier bridge T1 connects electric capacity C2、The negative electrode of diode D1 and the pin 1 of chip IC 1,The canthus 3 of chip IC 1 connects electric capacity C3 and LED lamp A,The other end of electric capacity C2 connects the other end of electric capacity C3、The pin 2 of chip IC 1、The other end of LED lamp A、The port 4 of rectifier bridge T1 and the port 4 of rectifier bridge T2,The anode of diode D1 connects the drain electrode of metal-oxide-semiconductor Q1,The source electrode of metal-oxide-semiconductor Q1 connects resistance R1、Electric capacity C1 and the positive pole of accumulator E,The negative pole of accumulator E connects the other end of electric capacity C1、Electric capacity C2、The emitter stage of audion V1、The fixing end of of potentiometer RP1、The colelctor electrode of the other end connecting triode V1 of resistance R1 and the grid of metal-oxide-semiconductor Q1,The base stage of audion V1 connects the sliding end of potentiometer RP1.
Diode D1 is light emitting diode.
Operation principle of the present utility model is: circuit divides duplex feeding, and first, 220V line voltage is after transformator W blood pressure lowering, then exports after rectified bridge T1 rectification, electric capacity C2 filtering, three terminal regulator IC1 voltage stabilizing, for load A work.Meanwhile, line voltage filters the DC voltage produced be added to the base stage of V1 through RP1 dividing potential drop also by rectifier bridge T2 rectification, electric capacity C2, and V1 turns on, and Q1 ends.When commercial power interruption, V2 is transferred to cut-off by conducting, now metal-oxide-semiconductor Q1 conducting, and accumulator E is added on mu balanced circuit by Q1, and output galvanic current pressure is cut A for negative, thus reached the continual purpose of accumulator.
