Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present invention.
Embodiment
In order to state details and the advantage thereof of technical solutions of the utility model better, be now described further by reference to the accompanying drawings.
As shown in Figure 1, a kind of Novel firefighting extra exit emergency light circuit, comprises power circuit, function control circuit, storage battery BT1, LED light circuit and emergency light circuit;
As shown in Figure 1, described function control circuit comprises triode Q1, Q2 and field effect transistor Q3, the base stage of described triode Q1 connects power circuit through resistance R1, R3, Q2 collector electrode is connected through resistance R7, R10, the base stage of Q1 and emitter are connected with the terminal A of hand switch SW, B respectively, the negative electrode of Q1 collector electrode connecting luminous diode D11, the anode of D11 connects power circuit through resistance R4, R11, the grounded emitter of Q1;
The grid of described field effect transistor Q3 connects through the base stage of resistance R7 and Q1, is connected with Q2 collector electrode through resistance R10, is connected with the collector electrode of Q1 simultaneously, and by RC filter circuit ground connection; The drain electrode of Q3 connects through the base stage of resistance R8 and Q2, the source ground of Q3; The emitter of described triode Q2 is connected with storage battery BT1 positive pole.
Wherein, described LED light circuit comprises LED 1 and LED2, LED2 and LED1 connect with resistance R18, R20 respectively, and then LED2, R18 and LED1, R20 parallel connection is connected with diode D7 anode again, and the negative electrode of D7 connects storage battery BT1 positive pole; The anode of LED1 with LED2 is connected with the negative electrode of diode D5, D6, and the anode of D5 is connected with power circuit through resistance R11, and the anode of D6 is connected with storage battery BT1 positive pole through resistance R17.
Described emergency light circuit comprises three emergency light Lamp1, Lamp2 and Lamp3 in parallel, and Lamp1 is connected with storage battery BT1 through resistance R9, and Lamp2 connects diode D7 anode, and Lamp3 connects storage battery BT1 anode through electric capacity C3.
Described power circuit after bridge rectifier, flows through fuse F1 by three-phase alternating current, and through RC filter circuit, a route D5 flows through LED1, LED2, then connects storage battery BT1 positive pole through D7, and accumulators BT1 charges, storage battery BT1 minus earth; Another road flows through R4, D11, Q1 to ground.
