Description

High-efficiency energy-saving lamp used in power cut

The utility model belongs to lighting technical field, is a kind of energy-efficient emergency light.

Present employed emergency light generally all is made up of charger, battery, incandescent lamp three parts, and this emergency light all exists the shortcoming that energy consumption is big, brightness is low, lighting hours is short, service life is not long, and function singleness, can only use for illumination.

The purpose of this utility model be to provide a kind of luminous efficiency height, energy-conservation, brightness is high, lighting hours is long, the energy-efficient emergency light of multiple function.

The purpose of this utility model realizes with the following methods.This energy-efficient emergency light comprises charger, battery, lamp, the cathode output end of battery connects switch, connect electric ballast then, electric ballast connects the negative pole of battery again, electric ballast is by triode, transformer is formed, transformer is by two primary coils, a secondary coil constitutes, the input termination switch of a primary coil, the colelctor electrode of output termination triode, the emitter stage of the input termination triode of another primary coil, the base stage of output termination triode, the base stage of triode also is connected with switch, transistor emitter also is connected with the negative pole of battery, lamp is a fluorescent lamp, its two ends filament is connected with the two ends of the secondary coil of transformer, and the two ends filament also is connected with electric capacity.The utility model will be further described below in conjunction with the embodiment accompanying drawing.

Fig. 1 the utility model circuit theory diagrams;

Fig. 2 is the utility model structural front view;

Fig. 3 is the rear view of Fig. 2.

Among the figure: 1-indicator lamp (D), 2-voltmeter; The 3-charging socket, 4-charger, 5-battery, the 6-switch, 7-electric ballast, 8-lamp, the 9-transformer, 10-accessory power outlet, 11-quartz clock, the L-live wire, N-zero line, R-resistance, the D-light emitting diode, C-electric capacity, G-triode, the Q-bridge rectifier, a, b-transformer, d-transformer secondary output coil.

Switch (6) is a third gear switch, and one grade (K1) is in parallel with third gear (K3) in series resistor (R2) back, and second gear (K2) is a neutral gear.The fluorescent lamp that lamp (8) adopts is a rare earth double hose fluorescent lamp, has that power is little, the high incandescent lamp that is equivalent to 40W as the fluorescent lamp brightness of 9W of luminous efficiency.Accessory power outlet (10) is located and is connect at output two ends at battery (5), this accessory power outlet (10) radio cassette player of both can having pegged graft, also can connect the negative pole and the ground wire of commutation diode in the black and white television set, therefore, the utility model is when having a power failure suddenly, both can be used for illumination, also can be used as radio cassette player, the required power supply of black and white television set use, on the shell of charger (4), fix a quartz clock (11), so both can be used for taking the time, also can be used for grasping the time (generally once charging 6-12 hour) that battery (5) at ordinary times charges.

Before the utility model uses, at first charge, with 220 volts of alternating currents of charging socket (3) grafting, indicator lamp (1, D) is bright, show that charger (4) charges at accumulators (5), accumulators (5) charging after the electric capacity (C1) of the charger (4) of 220 volts alternating current process and the step-down of bridge rectifier (Q), the rectification, charging interval 6-12 hour.Meeting power failure, when needing to use the utility model to be used to throw light on, if battery (5) is when just having charged electricity, the output voltage of battery is higher, then switch can be beaten at one grade (K1) from second gear (K2), make circuit insert resistance (R2), after suitably reducing voltage, use power supply sub-ballast (7), if used a period of time after battery (5) charging, then output voltage is not high, then switch (6) can be beaten at third gear (K3) from second gear (K2), and the electric current of the output sub-ballast (7) that directly powers is used.After switch (6) is connected, the base stage of triode (G) obtains bias current, make triode (G) conducting, be in the work of triode amplification region, and make primary coil (a) electric current of increase gradually be arranged by producing inductance, and the inductive drop that primary coil (b) is produced is coupled to the base stage of triode (G) by electric capacity (C2), make triode enter saturation region operation, the electric current that flows through primary coil (a) so no longer increases, the induced voltage of primary coil (b) disappears, the duty of triode withdraws from the saturation region again, the electric current that flows through primary coil (a) reduces again, cause that primary coil (b) produces and reverse inductance last time, backward voltage is added on the base stage of triode (G), make the duty of triode (G) enter cut-off region, primary coil (a) does not just have electric current to flow through, primary coil (b) does not just have electric current and inductance yet, return to original state so again, the base stage of triode (G) obtains bias current by biasing circuit again, triode (G) conducting, primary coil (a) has electric current to flow through again, so circulation repeatedly, just produce oscillating current, secondary coil (d) is boosted start fluorescent lamp (8), fluorescent lamp is lighted, and electric capacity (C4) provides a little constant current to tube filament, but prolonging lamp tube service life (fluorescent tube be difficult for blackout) like this.The other electric capacity (C3) of triode (G) can absorb higher hamonic wave, has improved the voltage waveform of primary coil (a) output greatly, and the waveform that makes secondary coil (d) output is near square wave, helps prolonging lamp tube service life.When other consumer need be used direct current, as long as plug with accessory power outlet (10).

The utlity model has simple in structure, adopt the rare earth fluorescent lamp to make electric light source, have that brightness is big, energy-saving effect is remarkable, lighting hours is long, compares with the existing emergency light of incandescent lamp that adopts, and measures and improves at least 4-5 doubly, lighting hours can prolong nearly 10 times, and except illumination, also can connect other household electrical appliance such as radio cassette player, black and white television set etc., therefore have multi-functional, energy-efficient.
