With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Accompanying drawing 1 is the circuit diagram of emergency light control circuit in this utility model embodiment；
In figure,
1-charging circuit, 2-protection circuit, 3-discharge circuit.
Detailed description of the invention
Embodiment, as it is shown in figure 1, a kind of emergency light control circuit, including the charging circuit 1 electrically connected with rechargeable battery E, protection circuit 2 and discharge circuit 3；
Protection circuit 2 includes resistance R1, resistance R2, photoconductive resistance R3, adjustable resistance RP, electric capacity C1, electric capacity C2, nor gate U2, audion Q1, diode D1 and relay K A1；
One end of resistance R1, the positive output end of the one termination rectifier bridge DB of electric capacity C1, one end of another termination capacitor C2 of resistance R1, one end of resistance R2, one input of nor gate U2, the other end of another termination capacitor C2 of electric capacity C1, the emitter stage of another termination audion Q1 of resistance R2, the base stage of audion Q1 connects the outfan of nor gate U2, one end of another input termination photoconductive resistance R3 of nor gate U2, one end of adjustable resistance RP, the other end ground connection of adjustable resistance RP, one end of the collector connecting relay KA1 coil of audion Q1, the positive pole of diode D1；
