Accompanying drawing explanation

Fig. 1 is the circuit diagram that low-power consumption touches LED circuit of corridor light.

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 low-power consumption touches LED circuit of corridor light, comprises resistance R7, triode V1, electrode slice M and chip IC 1, one end contact resistance R5 of described resistance R7, the negative electrode of diode D1, electric capacity C1, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end of resistance R7 connects electric capacity C2, the collector electrode of resistance R8 and triode V2, the other end of the emitter contact resistance R5 of triode V2, resistance R6, the pin 2 of chip IC 1 and the pin 6 of chip IC 1, the base stage contact resistance R3 of triode V2, the other end of the other end contact resistance R1 of resistance R3 and electrode slice M, electric capacity C2 connects electric capacity C3, electric capacity C1, the emitter of triode V1, LED group H, resistance R6, the pin 1 of resistance R9 and chip IC 1, the base stage of other end connecting triode V1 of resistance R1 and the collector electrode of triode V3, the pin 3 contact resistance R4 of chip IC 1, the other end of resistance R4 connects the control pole of unidirectional thyristor Q1 and the other end of resistance R9, the emitter of triode V1 connects the anode of diode D1, the negative electrode of unidirectional thyristor Q1 connects the other end of LED group H, and the model of described chip IC 1 is NE555.

Resistance R9 is photo resistance.

Operation principle of the present utility model is: under normal circumstances, and during unmanned Touching electrode M, triode V1 and unidirectional thyristor Q1 is all in cut-off state, and at Q1 off state, whole circuit does not consume electric energy.When touching sheet metal M with hand, the electric current of human body is leaded up to R1 and is added to VT1 base stage, and make VT1 conducting, electric capacity C1 is charged rapidly.A point voltage rises along with the voltage rise on C1, when A point voltage is greater than the conducting voltage of Q1, triode V2 conducting, thus make 3 pin of chip IC 1 export high level, if be now daytime, then due to reason that photo resistance R9 is low resistance state, the control pole of unidirectional thyristor Q1 must not be electric, and when only having insufficient light, resistance R9 is high-impedance state, Q1 obtains trigger voltage through R4 and to be triggered conducting, and LED group H is lit.At this moment can open hand-held.But switch oneself maintains conducting.Within several seconds after switch conduction, C2 will be filled electricity, V3 is conducting thereupon, and after staff leaves, electric capacity C1 maintains work a period of time of chip IC 1 to circuit discharging, guarantee unidirectional thyristor Q1 constant conduction, after a period of time, 3 pin of chip IC 1 export reversion, negative from just becoming, Q1 loses trigger voltage and turns off voluntarily, and lamp group H extinguishes.
