Description

A kind of simple and practical LED emergency light
Technical field
The utility model relates to a kind of emergency light, specifically a kind of simple and practical LED emergency light.
Background technology
Emergency light is lighting apparatus common in daily life, from market, basement has outfit to common residential building, but current emergency light great majority need to be equipped with separately light source to be increased extra cost and takes up room, this kind of emergency light mostly is storage battery power supply simultaneously, but running into long-term situation about having a power failure just cannot normal power supply, and existing emergency light function is comparatively single.
Utility model content
The purpose of this utility model is the simple and practical LED emergency light providing a kind of structure simple, easy to use, 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 simple and practical LED emergency light, comprise switch S 1, switch S 2, triode VT1 and resistance R4, one end connecting valve S2 of described switch S 1 and the positive pole of power supply E, the other end contact resistance R1 of switch S 1 and the emitter of triode VT2, the collector electrode of triode VT2 connects electric capacity C2, resistance R2, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end contact resistance R5 of resistance R1, the base stage of resistance R6 and triode VT2, the other end contact resistance R7 of resistance R6 and power supply VCC, the other end ground connection of resistance R7, the other end contact resistance R8 of switch S 2, the other end contact resistance R3 of resistance R8 and the base stage of triode VT1, the other end contact resistance R4 of resistance R3 and the pin 3 of chip IC 1, the pin 2 of chip IC 1 connects the pin 6 of electric capacity C1 and chip IC 1, the collector electrode of the other end connecting triode VT1 of resistance R2, the emitter of triode VT1 connects LED group H, the other end ground connection of LED group H, the model of chip IC 1 is LM555.
As preferred version of the present utility model: described resistance R1 is photo resistance.
As preferred version of the present utility model: described power supply E is the dry cell of 2 joint 1.5V.
Compared with prior art, the beneficial effects of the utility model are: the utility model LED emergency light circuit adds emergency service element on the basis of general lighting lamp, and use dry cell as the power supply of emergency light, can power for a long time, it is convenient to change, and there are light-operated and straight control two kinds of modes, therefore have that cost of manufacture is low, diverse in function, convenient and practical advantage.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of simple and practical 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 simple and practical LED emergency light, comprise switch S 1, switch S 2, triode VT1 and resistance R4, one end connecting valve S2 of described switch S 1 and the positive pole of power supply E, the other end contact resistance R1 of switch S 1 and the emitter of triode VT2, the collector electrode of triode VT2 connects electric capacity C2, resistance R2, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end contact resistance R5 of resistance R1, the base stage of resistance R6 and triode VT2, the other end contact resistance R7 of resistance R6 and power supply VCC, the other end ground connection of resistance R7, the other end contact resistance R8 of switch S 2, the other end contact resistance R3 of resistance R8 and the base stage of triode VT1, the other end contact resistance R4 of resistance R3 and the pin 3 of chip IC 1, the pin 2 of chip IC 1 connects the pin 6 of electric capacity C1 and chip IC 1, the collector electrode of the other end connecting triode VT1 of resistance R2, the emitter of triode VT1 connects LED group H, the other end ground connection of LED group H, the model of chip IC 1 is LM555.
Resistance R1 is photo resistance.Power supply E is the dry cell of 2 joint 1.5V.
Operation principle of the present utility model is: the power supply VCC in circuit is the electric energy of line voltage after rectifying and wave-filtering, and E1 battery (3V) positive pole receives triode VT2 emitter by switch S 1.Usually, have outer light source irradiation on photo resistance R1, its resistance is less, makes VT2 base potential higher with R5 dividing potential drop, and VT2 ends; When not having outer light source irradiation at R1, its resistance increases, with R5 dividing potential drop, VT2 base potential is declined, VT2 conducting, chip IC 1 timer obtains electric starting of oscillation, and R4, C1 determine the time constant of IC1 timing circuit, its 3. pin output pulse width be the signal of 700ms, deliver to the base stage of VT1 through R3, VT1 conducting repeatedly, cut-off, drive high brightness LED H to glitter and make lighting source.When dispatch from foreign news agency is powered normal, what rectification circuit provided 6V voltage to emergent flash light carrys out electric control signal, and this voltage delivers to the base stage of VT2 through R6, and its base potential is raised, the reverse-biased cut-off of VT2, and IC1 dead electricity does not work, and VT1 ends, and H extinguishes.Close S2, no matter which kind of state S1 is placed in, and the equal conducting of VT1, H Chang Liang.
