Emergency light of the present utility model is arranged at the top of shell (1), and is controlled by electronic switching circuit, makes it when alternating current 220V has a power failure, and realizes emergency lighting.
The utility model compared with prior art adopts electron luminescence to shield the light source of giving instruction, and it is reliable that it not only has working stability, and control is convenient, and luminance brightness is adjustable.Have little power consumption simultaneously, production cost is low, long service life.And can guarantee under the situation that civil power stops to supply with, to carry out advantages such as safe escape and emergency lighting.
Below in conjunction with accompanying drawing the utility model is illustrated,
Fig. 1 is an agent structure synoptic diagram of the present utility model;
Fig. 2 is a circuit block diagram of the present utility model;
Fig. 3 is a circuit structure diagram of the present utility model.
As shown in Figure 1: shell (1), electron luminescence screen (2), emergency light (3), power light (4), switch (5).
As shown in Figure 2: when 220 volts of inputs of alternating current, after the transformer step-down, through the direct current signal of rectification output, the one tunnel is connected to battery pack (10) and over-discharge protection circuit (12), electronic switching circuit (11) and illuminating lamp (3) through voltage stabilizer (9) output.Another road is connected to oscillator (13) and electroluminescence screen (2) through voltage stabilizer (8).
The principle of work of this circuit is as shown in Figure 3: exchange 220 volts of voltages after becoming device T1 step-down, be divided into two-way through the d. c. voltage signal of rectifier U1 output, the one tunnel charges to battery pack GB1 through voltage stabilizer N1 and isolating diode V3.Another road by switch S A1 through voltage stabilizer N2 and isolating diode V5, add to the push-pull oscillator circuit of forming by triode V11, V12 etc., this circuit gets electric signal work and produces ac high-voltage and excites the electroluminescence screen work that is connected its output terminal.DC voltage on the battery pack adds to the electronic switching circuit of triode V6, V9, V10 and resistance R 5, R7, R8 composition.In addition, the DC voltage of N1 output adds to the over-discharge protection circuit of being made up of jointly triode V4, resistance R 3, R4, diode V7, capacitor C 3 through diode V2.When the direct current signal of rectifier output added to the base stage of triode V6, V9, V10 by diode V1, its base voltage was higher than emitter voltage, then these three pipe not conductings this moment, and emergency light is not worked.When exchanging 220 volts of power failures, because rectifier U1 no-output voltage, the emitter voltage of triode V6, V9, V10 is higher than base voltage, and then triode V6, V9, V10 begin conducting, makes the luminous work of illuminating lamp HL2, HL3 that is serially connected in triode V9, V10 collector.Voltage on the battery pack is delivered to the oscillatory circuit of being made up of triode V11, V12 etc. through the collector output of triode V6 simultaneously, and excites electroluminescence screen to work on.Thereby both realized the safe escape indication, realized the purpose of emergency lighting again.In addition, the luminance brightness of luminescent screen is adjusted by adjustable resistance RP1.
This device guarantees that in order to guarantee the serviceable life of accumulator battery pack discharges and recharges function effectively, the special over-discharge protection circuit of being made up of triode V4, resistance R 3, R4, diode V2, V7, capacitor C 3 that is provided with in circuit.When the sparking voltage of accumulator drop to rated voltage 80% the time; just less than 0.7 volt, V4 ends the base voltage of triode V4 in the circuit, causes triode V6, V9, V10 also to end; cut off the voltage output of accumulator simultaneously, thus protection charging and discharging of accumulator function.
