Abstract
The utility model designs an automatic emergency lighting circuit in power failure comprising a relay, wherein the relay is provided with two contact points, namely a contact point K1 and a contact point K2, and a battery pack E is connected between a power line and a null line behind a voltage-regulator diode D2 through the contact point K2 of the relay K; when the lighting circuit supplies the power, the battery pack E is communicated with the power line of the lighting circuit through the contact point K2 of the relay so as to carry out floating charge on the battery pack E; and when the lighting circuit is in the power failure, a light bulb ZD is lightened when the contact point K1 is communicated with the battery pack. The automatic emergency lighting circuit in power failure has simple structure and low cost, can be artificially powered on or off according to time, and can achieve the purpose of being powered on during the needed time section, thereby responding to the call of China on low-carbon discharge.
Description
Technical field
The utility model relates to the application of electronic technology field, in particular to the emergent automatic lighting circuit of a kind of power failure.
Technical background
Do not have the emergency case of sign in some of personnel concentrated area institute (for example office building, cinema, market, school instruction building etc.) such as fire, earthquake etc., with make be in these ground people's lives and properties endangered.When above-mentioned emergency case takes place, very likely make the normal lighting circuit break down, therefore influence the speed of emergency evacuation.Provide emergency-lighting set in the prior art for this reason, made and when emergency case occurs, can use existing emergency-lighting set to assist crowd's evacuation.Yet existing emergency-lighting set is need be manually opened a bit, needs to open artificially the mains switch of emergency-lighting set after promptly having a power failure, and is not convenient in the use; Some is controlled by Fire Net, and its cost is quite high; Some is long-term unlatching, has consumed unnecessary electric energy, can not reach the purpose of low-carbon emission.
Summary of the invention
The utility model is designed the emergent automatic lighting circuit of a kind of power failure at above-mentioned situation, comprise a switch S, a battery pack E, a bulb ZD, capacitor C 1, capacitor C 2, resistance R, voltage stabilizing didoe DW, diode D1, D2, and a relay K, this relay comprise two contact K1 and K2; It is characterized in that: above-mentioned switch S, capacitor C 1 and diode D1, D2 are connected on the live wire successively, and circuit, the relay K that capacitor C 2, resistance R are connected with voltage stabilizing didoe DW is connected in parallel between the live wire and zero line between voltage stabilizing didoe D1 and the D2; Battery pack E is connected between the voltage stabilizing didoe D2 live wire and zero line afterwards by the contact K2 of relay K, and during the lighting circuit power supply, battery pack E is communicated with the live wire of lighting circuit by the contact K2 of relay K, to battery pack E floating charge; The contact K1 of bulb ZD and battery pack E, relay forms series circuit, and when lighting circuit had a power failure, when relay contact K1 was communicated with battery pack, bulb ZD was lighted.
Description of drawings
Accompanying drawing 1 is the circuit diagram of the emergent automatic lighting circuit of power failure.
Embodiment
As shown in Figure 1, the emergent automatic lighting circuit of a kind of power failure that the utility model proposes comprises following element:
A switch S, be used to control the unlatching of entire circuit or close, by day, sufficient daylight illumination is arranged in the corridor in some place or the passageway, therefore S can be placed open position, place on-position with switch S night, avoids relay K to be in attracting state for a long time, to increase the service life;
A battery pack E can select No. 1 1.5V battery of four joints or 6V storage battery, is beneficial to floating charge;
A relay K, this relay comprises two contact K1 and K2, under the situation of switch S closure, K2 is communicated with battery E, and the normal lighting circuit charges to battery pack E, in case civil power has a power failure suddenly or blown fuse, the relay K dead electricity discharges, and normally-closed contact K1 closure is connected bulb power ZD, miniature bulb is lighted, and realizes emergency lighting.As a nonrestrictive execution mode, it is the 6V direct current relay of HG4098 that relay K can adopt model, electric current 90～100mA.
A bulb ZD:6.3V, the incandescent miniature bulb of 0.15A.
And:
Capacitor C 1 (can select 1 μ F/400V for use), capacitor C 2 (can select 100 μ F/16V for use), resistance R (optional 33k Ω);
Voltage stabilizing didoe DW (optional 6V voltage stabilizing didoe);
Diode D1, D2 (optional IN4007 type diode).
Above-mentioned switch S, capacitor C 1 and diode D1, D2 are connected on the live wire successively, and circuit, the relay K that capacitor C 2, resistance R are connected with voltage stabilizing didoe DW is connected in parallel between the live wire and zero line between voltage stabilizing didoe D1 and the D2;
Battery pack E is connected between the voltage stabilizing didoe D2 live wire and zero line afterwards by the contact k2 of relay K, and during the lighting circuit power supply, battery pack E is communicated with the live wire of lighting circuit by the contact K2 of relay K, to battery pack E floating charge;
The contact k1 of bulb ZD and battery pack E, relay forms link in tandem; When lighting circuit had a power failure, when relay contact K1 was communicated with battery pack, bulb ZD was lighted.
When the civil power normal power supply, the 220V alternating current is through capacitor C 1 step-down, diode D1 halfwave rectifier and capacitor C 2 filtering, obtain stable 6V direct voltage and make the relay K action, its normally-closed contact K1 disconnects the DC power supply of miniature bulb ZD, miniature bulb does not work, normally opened contact K2 closure at this moment, and pulse current carries out floating charge to battery.In case civil power has a power failure suddenly or blown fuse, the relay K dead electricity discharges, and normally-closed contact K1 closure is connected the miniature bulb power supply, and miniature bulb is lighted, and realizes emergency lighting.
The emergent automatic lighting circuit of power failure described in the utility model can not need printed circuit board (PCB), and all elements are installed on the insulation board, connects with line, is fixed on interior the getting final product of plastic casing of corresponding size, thereby saves cost.The more important thing is, it can open the emergency lighting circuit automatically when having a power failure, and circuit structure is simple, cost is low, and can open or close the emergency lighting circuit according to the time artificially, can accomplish to open the emergent automatic illuminating lamp that has a power failure, respond the aim of national low-carbon emission in the time period of needs.
