Abstract
The utility model relates to a high lightness illuminating emergency lamp, when the main electricity is in use, the lamp can illuminate by the main electricity, and when powering off, the lamp can illuminate by a battery. The lamp comprises a charging circuit, a charging battery, a discharging control circuit, an inverse transformation boosted circuit, a converting circuit, a lamp start and limit circuit, an amperite, a starter, a lamp tube and a bracket, and because the lamp start and limit circuit comprises an inductance, a converting switch and a capacitance, the utility model not only has the illumination function but also can be used for emergency in the power-off and keep the illumination lightness when the main electricity is in use. The circuit of the utility model has the advantages of simple and practical structure and advanced and low cost, and the lamp is a novel high lightness illuminating emergency lamp.
Description
The utility model relates to a kind of emergency light, and particularly a kind of city's electric lighting that uses when civil power is arranged uses the highlight illumination emergency light of battery illumination during outage.
Use at present with the emergency light of fluorescent lamp as light source, when often commercial power supply being arranged, emergency light does not work, and when civil power disconnects, the battery that just automaticallyes switch throws light on and plays a part as power supply and meets an urgent need.There is following shortcoming in this emergency light: can not directly use civil power to throw light on as power supply, and brightness is not high during emergent the use, does not often reach 50% of normal wattage luminosity, is difficult to reach the effect of high brightness.
The purpose of this utility model is to solve the shortcoming that exists in the above-mentioned prior art and a kind of both available city electric lighting is provided, conversion battery is as the emergency light of power supply illumination automatically again during outage, and the brightness of the brightness of illumination when this emergency light is emergent during with the use civil power is the same.
The purpose of this utility model can realize by following measure, the utility model is by charging circuit, rechargeable battery, charge/discharge control circuit, inversion step-up circuit, start and current-limiting circuit, change-over circuit, ballast, starter, fluorescent tube, support is formed, it is characterized in that: lamp start and current-limiting circuit by inductance L 1, change over switch J1-2, J1-3, capacitor C 4 is formed, the end of L1 and the secondary line chart of transformer B2 join, the fixed contact of often opening of the other end of L1 and J1-2 joins, and an end of the moving contact of J1-2 and one group of filament of fluorescent tube joins, and the other end of this group filament and the moving contact of J1-3 join, the end of often opening fixed contact and capacitor C 4 of J1-3 joins, the normally closed fixed contact of J1-3 and the end of starter S1 join, capacitor C 4 and open the other end of waving device S1 and end of another group filament of fluorescent tube joins, and the other end of the secondary coil of other end filament and transformer B2 joins.
Fig. 1 is a functional-block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Fig. 3 is a shape assumption diagram of the present utility model.
The utility model is described further below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 3, the utility model is by charging circuit 1, rechargeable battery 2, charge/discharge control circuit 3, inversion step-up circuit 4, lamp starts and current-limiting circuit 5, change-over circuit 6, ballast 7, starter 8, fluorescent tube 9, support 10 is formed, and wiring board 11 is encapsulated in support 10 the insides, the two ends 12 of wiring board 11 or 13 and civil power join.When civil power, electric current is through ballast, and change over switch, starter make fluorescent lamp lighting to fluorescent tube, simultaneously by charging circuit to battery charge; During outage, battery makes inverter circuit work through charge/discharge control circuit, boosts after lamp start-up circuit and change over switch make lamp tube starting, and the flow restricter current limliting keeps the fluorescent tube normal brightness then.
With reference to Fig. 2, diode D1, D2, D3, D4, capacitor C 2 is formed current rectifying and wave filtering circuit; The voltage stabilizing current-limiting circuit is by three-terminal voltage-stabilizing ic chip 1, diode D6, and resistance R 1 is formed; Transformer B1, current rectifying and wave filtering circuit and voltage stabilizing current-limiting circuit constitute charging circuit 1; Charge/discharge control circuit 3 is by triode Q1, Q2, Q3, resistance R 2～R6, and diode D7, D8, capacitor C 1, relay J is formed; Inversion step-up circuit 4 is by ic chip 2, resistance R 7～R11, and capacitor C 3, field effect transistor Q4, Q5, transformer B2 forms; Lamp start and current-limiting circuit 5 by inductance L 1, change over switch J1-2, J1-3, capacitor C 4 is formed.
When commercial power supply, the base stage of triode Q2 is an electronegative potential in the charge/discharge control circuit 3, triode Q2 ends, triode Q1, Q3 also end, and the coil no current of relay J passes through, not adhesive of relay J, civil power is through ballast L2, change over switch J1-2, the normally-closed contact of J1-3, two groups of filaments of fluorescent tube and starter S1 make lamp tube starting; When no commercial power supply or outage, capacitor C 2 is by the base stage discharge of 2 couples of triode Q2 of resistance R, triode Q2 conducting, also conducting of triode Q1, Q3, the relay J adhesive, ic chip 2 is started working, and drives field effect transistor Q4, Q5 work, produces High Level AC Voltage at the secondary coil two ends of transformer B2, by inductance L 1, diverter switch J1-2, J1-3 often open fixed contact, moving contact, capacitor C 4, two groups of filaments of fluorescent tube, fluorescent tube forms discharged in series, the high pressure that produces makes lamp tube starting, and 1 metering function of inductance L keeps fluorescent tube normally luminous.
As the city power recovery supply, the triode Q3 in the charge/discharge control circuit ends, triode Q1, Q3 end thereupon, and relay J discharges, and fluorescent lamp returns to mains-supplied.
The utility model compared with prior art has following advantage:
1. can use as the general lighting of mains-supplied, also can when outage, use as emergency light.
2. when using as emergency light, the original brightness when having kept former mains-supplied.
3. line construction is simply advanced, with low cost, is a kind of novel illumination emergency light.
