As preferred version of the present utility model: described resistance R6 is photo resistance.
Compared with prior art, the beneficial effects of the utility model are: the utility model energy-saving photo-controlled LED emergency light circuit structure is simple, components and parts are few, use LED lamp as light source, and add in the module of emergency flight control as light-dependent control element, circuit only just can be opened when having a power failure at insufficient light, therefore there is the advantage of saves energy, long service life and stable performance.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of energy-saving photo-controlled LED emergency 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 energy-saving photo-controlled LED emergency light, comprises resistance R1, triode VT1, switch S and storage battery E, one end of described resistance R1 connects electric capacity C1 and 220V alternating current, and the other end of resistance R1 connects the other end of electric capacity C1, the anode of diode D1, the other end of resistance R3 and transient voltage suppressor diode DW, resistance R3 connects the anode of unidirectional thyristor Q1, and the negative electrode of diode D1 connects the negative electrode of diode D2, the anode of diode D3, resistance R4, the other end of resistance R5 and electric capacity C2, transient voltage suppressor diode DW connects the other end of electric capacity C2, resistance R6, the emitter of triode VT1, LED group H, the negative pole of storage battery E and the other end of 220V alternating current, the base stage of the anode connecting triode VT1 of diode D2, the other end of the collector electrode contact resistance R4 of triode VT1, the other end of other end contact resistance R6 of resistance R5 and the base stage of triode VT2, the emitter connecting valve S of triode VT2, the other end contact resistance R7 of switch S, the positive pole of storage battery E and the negative electrode of unidirectional thyristor Q1, the other end of negative electrode contact resistance R7 of diode D3 and the control pole of unidirectional thyristor Q1.
Resistance R6 is photo resistance.
Operation principle of the present utility model is: 220V civil power is through R1, C1 step-down, D1 rectification, C2 filtering, and then via D2, VT1, the simple and easy shunt regulator voltage stabilizing of R4 composition obtains the direct voltage of about 8.2V, what circuit adopted is 6V small-sized sealing storage battery, when its voltage reduces, the pressure drop that R7 produces makes thyristor Q1 conducting, therefore through C1, the electric current of R1 is by R2, R3 current limliting, half-wave trickle charge is carried out to storage battery, this charging modes accumulator electric-quantity foot, discharge stability, lighting hours is long, when battery tension reaches 7V-7.5V, it makes D3 end through R7, Q1 is blocked by current over-zero, charging stops.As long as therefore storage battery electric energy loss makes its terminal voltage decline, circuit will supplement at any time.Power cut detection circuit in this emergency light is made up of R5, R6, VT2, as long as electrical network has electricity, the output voltage stabilizing of circuit makes the emitter junction of VT2 end through R5, R6 dividing potential drop, and the lamp D2 of VT2 collector electrode does not work; Once grid power blackout, storage battery makes VT2 base stage by only by the conducting of R6 positively biased, due to the light-operated function of R6, during daytime, its resistance is very low, is similar to short circuit, therefore triode VT2 not conducting, now LED group H is not luminous, and when only having night or cloudy day to cause insufficient light, the resistance of R6 is very large, now have a power failure just meeting trigger triode VT2, and lamp H is lit.
