Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises the first diode D1, second diode D2, 3rd diode D3, relay K, first resistance R1, second resistance R2, first electric capacity C1, second electric capacity C2, the first end of lighting bulb H and storage battery E, the first resistance R1 simultaneously with the positive pole of the second diode D2, the first end of the second resistance R2, the first end of the first electric capacity C1 is connected with the negative pole of the 3rd diode D3, and second end of the first resistance R1 is connected with the first end of relay K simultaneously, with the positive pole of the first diode D1 while of the second end of relay K, second end of the first electric capacity C1, the first end of lighting bulb H, the negative pole of storage battery E is connected with the zero line N of AC power, the negative pole of the first diode D1 is connected with second end of the second resistance R2, second end of lighting bulb H is connected with the first end of relay normally-closed contact K switch-1, second end of relay normally-closed contact K switch-1 is connected with the positive pole of storage battery E and the first end of relay normally open contact K switch-2 simultaneously, second end of relay normally open contact K switch-2 is connected with the negative pole of the second diode D2, the positive pole of the 3rd diode D3 is connected with the first end of the second electric capacity C2, and second end of the second electric capacity C2 is connected with the live wire L of AC power.
As shown in Figure 1: the utility model is when when utility grid normal power supply, the alternating voltage of 220V is through the second electric capacity C2 step-down, after 3rd diode D3 halfwave rectifier and the first electric capacity C1 filtering, for circuit supply galvanic current pressure, this direct voltage, for relay K work, inhale open relay normally-closed contact K switch-1 on the one hand, therefore lighting bulb H dead electricity does not work, attracting electric relay normally opened contact K switch-2, makes pulse current charge to storage battery E through the second diode D2 on the other hand; Once utility grid has a power failure, relay K dead electricity, release relay normally-closed contact K switch-1, thus light lighting bulb H, reach the object of automatic emergency lighting.
