Description

Full-automatic emergency electronic stabilizer

Technical field:

The utility model relates to a kind of supply unit, especially a kind of full-automatic emergency electronic stabilizer.

Background technology:

As everyone knows, night, outdoor work and business activities needed lighting apparatus, be to make lighting apparatus at present mostly with candle, acetylene lamp, gas lamp, it not only expends height, be subjected to environmental factor such as wind effect big, and illuminating effect is also very poor, though passing through at the indoor pulling wire that connects of having to the outdoor use lamp lighting, but use extremely inconvenience like this, just can't obtain light source in case have a power failure.People have developed the storage battery emergency light in recent years, but because the accessory units function of storage battery design imperfection, the very difficult use shape shape of in time knowing battery lacks automatic regulatory function, makes its useful life shorter, also can occur situation about can't use sometimes.

The utility model content:

The purpose of this utility model is to overcome the prior art deficiency, and the full-automatic emergency electronic stabilizer of automatic regulatory function of a kind of energy and indication performance state, long service life is provided.The purpose of this utility model realizes by following technical proposals: the utility model comprises housing, and housing is provided with lighting switch, indicator light window, charging plug, load connecting line and rechargeable battery connecting line; Be provided with transformer and the circuit board that is fixed on the housing in the housing; Lighting switch, indicator light, charging plug; the battery connecting line links to each other by the circuit on the circuit board with load connecting line, transformer; circuit board includes charging circuit, civil power indicating circuit, automatic saturated indicating circuit, automatic emergency circuit, inverter circuit, under-voltage indicating circuit and under-voltage protecting circuit; said automatic saturated indicating circuit is by resistance and voltage-stabiliser tube series connection; and link to each other with controllable silicon through diode, filter capacitor, shunt resistance, link to each other with light-emitting diode with two resistance again.Said under-voltage protecting circuit, is linked to each other with a transistor base through resistance with after resistance links to each other by electric capacity and voltage-stabiliser tube again, transistor collector with link to each other with another transistor base again after resistance, diode link to each other.

Description of drawings:

Fig. 1 is the utility model configuration diagram;

Fig. 2 is the utility model circuit theory diagrams.

Embodiment:

With reference to Fig. 1, Fig. 2; the utility model comprises housing 2; housing 2 is provided with lighting switch 6, indicator light window 3,4,5; charging plug 1, load connecting line 8 and battery connecting line 7; be provided with transformer TR1, circuit board in the housing 2; switch indicator light, socket, transformer link to each other by circuit, and circuit board includes charging circuit, civil power indicating circuit, automatic saturated indicating circuit, automatic emergency circuit, inverter circuit, under-voltage indicating circuit and under-voltage protecting circuit.As shown in Figure 2, each circuit working principle is as follows: charging circuit is after charging plug and civil power grafting, after opening switch SW, power supply is after power transformer TR1 transformation, pass through filter capacitor C1 filtering via bridge rectifier D1-D4 rectification again, be transferred to storage battery BT through diode D5 again and charge.The civil power indicating circuit offers LED 1 power supply by bridge rectifier by current-limiting resistance R1, makes its luminous indication.After automatic saturated indicating circuit obtains sampling by resistance R 2, R4 and voltage-stabiliser tube ZD1, through diode D9 filter capacitor C2, shunt resistance R5 adds to controllable silicon VS1 makes its conducting, because resistance R 6, R7 metering function, green LED LED2 lights with the indication charging saturated.The automatic emergency circuit by charging circuit connect diode D6, resistance R 3 provide high level after capacitor C 3 filtering again by resistance R 8 to triode Q1, make the Q1 conducting, make another pin of diode D7, D8 be in low level through resistance R 9, triode Q2 is ended, the inverter failure of oscillations, enter the automatic emergency state, triode Q2 conduction inverter starting of oscillation FL fluorescent tube is lighted automatically when mains failure.

Inverter circuit is by inductance L 1, triode Q5, Q6, and resistance R 16, R17, R18, compositions such as capacitor C 4, (TR2) produce high-frequency and high-voltage and supply with (FL) fluorescent tube through (C5), make lamp tube starting.Its frequency of oscillation, power output are set as required, and present embodiment is selected 25-30KHZ, 8-20W for use.

Under-voltage indicating circuit is by voltage-stabiliser tube ZD3, and resistance R 13 samplings obtain low level by resistance R 12, the last below-center offset of R14 again, and triode Q4 ends, and red light emitting diodes LED3 is lighted, (R19) current-limiting resistance.

Under-voltage protecting circuit by capacitor C 6 coupling, after voltage-stabiliser tube ZD2 sampling, resistance R 11 shuntings, offer triode Q1 by resistance R 10 again and make its conducting; make diode D8 negative terminal be low level over the ground by resistance R 9 over the ground through the Q1 conducting again, triode Q2 is ended to reach the purpose of protection.

During use, the charging plug load socket that links to each other with power supply is linked to each other lighting switch with tube face, the SW closure, this moment, electric stabilizer promptly entered automatic charged state, and LED1 lights automatically, and the LED2 that charges when saturated lights battery automatically and will enter and replenish electricity condition and can charge for a long time; LED1 extinguishes when exchanging power failure suddenly, and the FL fluorescent tube is lighted automatically, in the time of need not throwing light on as the while SW is turn-offed; When be discharged to battery when under-voltage the LED3 indicator light light with prompting and need charging, will automatically shut down as the fluorescent tube that do not charge immediately about 10 minutes and extinguish, remind charging to use once more, with protection battery useful life.

By above description as can be known, the purpose of this utility model can realize this practicality Novel compared with prior art have a following advantage, and the utility model can adapt to various nothings electricity rings Illumination under the condition of border, function are comparatively perfect, have automatic regulation function and duty Show the advantages such as long service life.
