Description

A kind of intelligent LED emergency light control circuit

Technical field

The utility model relates to a kind of lighting circuit, specifically a kind of intelligent LED emergency light control circuit.

Background technology

Emergency light is lighting electronic equipment common in daily life, from market, basement has outfit to common residential building, it can be opened when having a power failure or burst accident occurs and light, people are helped to find escape way, thus reduce the panic probability of happening with trampling accident, but current emergency light control circuit great majority adopt chip structure, cost of manufacture is higher, and the interference free performance of chip is poor, easily started by false triggering, cause the waste of electric energy, simultaneously this kind of emergency light mostly is an appearance and has a power failure the mode of opening at once, and daytime bright and clear time do not need emergency light, therefore more equipment loss and power consumption is increased.

Utility model content

The purpose of this utility model is to provide a kind of intelligent LED emergency light control circuit, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of intelligent LED emergency light control circuit, comprise resistance R1, electric capacity C1, storage battery E and relay J, one end of described resistance R1 connects electric capacity C1 and 220V alternating current, the other end of the other end contact resistance R1 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 and the 220V alternating current of transient voltage suppressor diode DW, the port 2 of rectifier bridge T connects electric capacity C2, relay J, the positive pole of storage battery E and the contact J-1 of relay J, the other end contact resistance R2 of the contact J-1 of relay J, resistance R5, a stiff end of potentiometer RP1 and the sliding end of potentiometer RP1, the other end of electric capacity C2 connects the other end of relay J, resistance R4, resistance R6, the negative pole of storage battery E, the emitter of triode V1 and the port 4 of rectifier bridge T, the other end contact resistance R3 of resistance R2 and the other end of resistance R4, the base stage of other end connecting triode V1 of resistance R3 and the other end of resistance R6, the other end of the collector electrode contact resistance R5 of triode V1 and or two inputs of door U1, or the output of door U1 connects or two inputs of door U2, or two of door U3 inputs and or two inputs of door U4, or the output of door U2 connects or the output of door U3, or the output of door U4 and LED group H, the other end of LED group H connects another stiff end of potentiometer RP1.

As preferred version of the present utility model: described relay J is normally-closed contact relay.

Compared with prior art, the beneficial effects of the utility model are: the utility model intelligent LED emergency light control circuit structure is simple, components and parts are few, use basic electronic component composition, chipless structure, add the anti-interference of circuit, and add light-dependent control element in circuit, circuit only just to be opened when having a power failure at insufficient light, therefore there is the advantage of the little and stable performance of saves energy, volume.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of intelligent 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 intelligent LED emergency light control circuit, comprise resistance R1, electric capacity C1, storage battery E and relay J, one end of described resistance R1 connects electric capacity C1 and 220V alternating current, the other end of the other end contact resistance R1 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 and the 220V alternating current of transient voltage suppressor diode DW, the port 2 of rectifier bridge T connects electric capacity C2, relay J, the positive pole of storage battery E and the contact J-1 of relay J, the other end contact resistance R2 of the contact J-1 of relay J, resistance R5, a stiff end of potentiometer RP1 and the sliding end of potentiometer RP1, the other end of electric capacity C2 connects the other end of relay J, resistance R4, resistance R6, the negative pole of storage battery E, the emitter of triode V1 and the port 4 of rectifier bridge T, the other end contact resistance R3 of resistance R2 and the other end of resistance R4, the base stage of other end connecting triode V1 of resistance R3 and the other end of resistance R6, the other end of the collector electrode contact resistance R5 of triode V1 and or two inputs of door U1, or the output of door U1 connects or two inputs of door U2, or two of door U3 inputs and or two inputs of door U4, or the output of door U2 connects or the output of door U3, or the output of door U4 and LED group H, the other end of LED group H connects another stiff end of potentiometer RP1.

Relay J is normally-closed contact relay.

Operation principle of the present utility model is: 220V civil power is through R1, C1 step-down, rectifier bridge T rectification, the two ends of relay J are added in after transient voltage suppressor diode DW voltage stabilizing, because the voltage of electric capacity C2 can not suddenly change, thus available protecting relay, when preventing its transient switching, electric current is excessive burns coil, relay J conducting after a period of time, its normally-closed contact J-1 disconnects, storage battery charges, when running into civil power power-off, relay J dead electricity, the J-1 conducting of its contact, emergency light circuit is connected, resistance R4 is photo resistance, if daytime, the resistance of resistance R4 is very low, therefore the base stage of triode V1 is in low level state, or door U1 exports high level, therefore U2 ~ U4 also exports high level, LED group H is not lit, only when insufficient light, photo resistance R4 is high-impedance state, the base stage of triode V1 is high level, triode V1 conducting, or door U1 output low level, therefore U2 ~ U4 also output low level, LED group H is lit luminescence, potentiometer RP1 conveniently can regulate the brightness of emergency light H.
