Fig. 1 is a circuit block diagram of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

In order to make the utility model technology clear more complete, the utility model is described in further detail below in conjunction with accompanying drawing.

The utility model is made lamp holder with electricity-saving lamp, is equipped with step-down rectifying circuit, constant voltage charging circuit, inverter circuit, the zero under-voltage automatic shutdown circuitry of loss, civil power, contrary electric automatic switching circuit formation.

1, step-down rectifying circuit: mainly be made up of transformer B1, the parts such as stream bridge QL, capacitor C 1 that shake, 220 volts of civil powers are through the B1 step-down, and QL rectification and C1 filtering are converted to the direct current about 22 volts.

2, constant voltage charging circuit: mainly by three-terminal regulator block IC1, rectifier diode D1, D2 form, 22 volts of direct currents are through three-terminal regulator block 7815 or the adjustable regulator block LM317 of three ends voltage stabilizing, D1, D2 step-down, become 13.6 volts constant voltage, this voltage is the best floating charge constant voltage of built-in 12V4AH sealing battery battery, can play to prolong the battery effect in useful life.

3, inverter circuit: by pulsewidth modulated intergrated circuit IC2, resistance R 6-R9, capacitor C 5, switching tube Q2, Q8 and high frequency transformer B2 form.12 pin of IC2 connect with J2 by resistance R 5,11 and 8 pin connect with 12 pin by resistance R 6,13,14 pin directly link, 1, the direct ground connection of 2,4,7,15,16 pin, 3 pin are unsettled, 5 pin are by capacitor C 5 ground connection, and 6 pin are by electric capacity R9 ground connection, and 9 pin and 10 pin link by the grid of resistance R 7 and R8 and switching tube Q2, Q3 respectively.After 8,11,12 pin of pulsewidth modulated intergrated circuit IC2 obtain 12 volts of positive voltages, 9 pin, 10 pin just can be exported one group of square-wave pulse that the amplitude same phase is opposite, rotate energizing switch pipe Q2 and Q3 respectively, 12 volts of storage battery direct currents just can pass through high frequency transformer B2 elementary and switching tube Q2, Q3, be transformed to the high-frequency alternating current about 220 volts, this high-frequency alternating current passes through the contact of control relay J1, the electric energy that load is used during as power failure.The operating frequency of this circuit is by the external appearance resistance decision of 5 pin and 6 pin of IC2, it is good generally being set in 20-60KHZ, the frequency of this circuit setting is 50KHZ, pulsewidth modulated intergrated circuit is the Switching Power Supply application-specific integrated circuit, the pulsewidth modulated intergrated circuit that SG3524, SG3525, MB3759, HA17494 and so on are arranged that performance is similar.

4, under-voltage automatic shutdown circuitry: form by under-voltage automatic shutdown control relay J2, triode Q1, capacitor C 4, resistance R 3, R4 and voltage stabilizing didoe ZD.Receive on the contact of J1-1 one termination of J2 coil, another termination be connected by the positive pole of the collector electrode of Q1, capacitor C 4 and an end in resistance R 3 loops that form in parallel, the emitter of triode Q1 is connected with the negative electrode of voltage-stabiliser tube ZD, the negative electrode of voltage-stabiliser tube ZD is in parallel with the negative pole resistance R3 of capacitor C 4, form the other end of shunt circuit, this end ground connection, diode D4 and J2 coils from parallel connection of coils in the circuit, resistance R 4 links by the normally opened contact of J2.When double-pole switch K1-2 connection, under the situation of J1-1 closure, 12 volts of positive voltages make the J2 adhesive by J2 coil and C4 ground connection, and 12 volts of positive voltages also arrive the Q1 base stage by R4, thereby make the Q1 conducting.Battery voltage just often, voltage-stabiliser tube ZD conducting, 12 volts of positive voltages just can pass through Q1, ZD over the ground, the J2 coil is firmly adhesive just, the inverter circuit of next stage is with regard to the energy operate as normal.When battery voltage is lower than 10 volts, the J2 coil voltage will be lower than 2 volts and discharge, and J2 just recovers normally open, and the inverter circuit of next stage turn-offs because of the voltage of losing the job, thereby realizes the purpose of under-voltage automatic shutdown.The effect of setting resistance flesh provides capacitor C 4 discharge paths.When inversion was shut down automatically, complete machine power consumption electric current was lower than 1 milliampere.Therefore this circuit can be described as the zero under-voltage automatic shutdown circuitry of loss.

5, civil power, contrary electric automatic switching circuit: mainly finish by J2, when civil power is arranged, three-terminal regulator block IC1 output has voltage, this voltage is added on the J1 coil through K1-1, R1, the J1-1 contact is disconnected, the intermediate contact of J1-2 engages with civil power, cuts off the path of IC1 and storage battery on the one hand, makes inverter be in closed condition; On the other hand, civil power provides path through the J1-2 intermediate contact to load.During power failure, IC1 no-output voltage, J1 discharges, the J1-1 conducting, IC2 obtains operating voltage, and inverter is open-minded, and simultaneously, the intermediate contact of J1-2 turns to contrary electricity end, and the electric energy of inversion powers to the load by J1-2.

Other explanations, this lamp K is a double-pole switch, and K1-1 and K1-2, have under the civil power situation when K opens with connection, and the IC1 output voltage passes through K1-1, R1 to the J1 coil power supply, the J1 adhesive, civil power powers to the load by the J1-2 intermediate contact.During power failure, battery voltage is powered to IC2 by K1-2, makes inverter open-minded; When K closes, have under the civil power situation, because of J1 opens circuit, J1-2 contact and civil power are thrown off, and load can not get civil power and does not work.When in like manner having a power failure, because of K does not open, K1-2 disconnects, and IC2 can not get operating voltage, and inverter cuts out, and does not have contrary electric output and load is turned off the light.

This circuit design power output maximum can reach 40 watts, no matter is unloaded or fully loaded output can both operate as normal, and this lamp adopts electronic energy-saving lamp to make lighting, can realize low energy consumption, high brightness.If require the power failure supporting time long, can select 7 watts energy-conservation lamp holder for use, if require big brightness, can adopt two-burner lamp to export, but the electricity-saving lamp of 20 watts of each lamp holder adapteds.This lamp is as if the electricity-saving lamp of single 11 watts of adapteds, brightness that can suitable 60 watts of incandescent lamps, select the capacity of 12V4AR (available two 6V storage batterys series connection) for use when built-in storage battery, can support the power failure lighting hours about 4 hours, this lamp is direct 15 watts of adapteds---40 watts ordinary incandescent lamp also, but non-energy-conserving product of ordinary incandescent lamp thereby the emergency light that can only be used as under the specific condition use.
