A kind of multi-functional evacuation pilot lamp, comprise housing 1 and be arranged on the interior accumulator 6 of housing, housing 1 is provided with evacuates index map chopping board 2, the inboard of evacuating index map chopping board 2 is provided with the evacuation pilot lamp, be provided with the lamp chamber at least one side body 1 in the upside of evacuation index map chopping board 2, downside, left side, the right side, be provided with emergency light 4 in the lamp chamber, emergency light 4 is connected with accumulator 6 with Switching Power Supply 9 by emergency lighting change-over circuit 5 respectively with the evacuation pilot lamp.Civil power is connected with Switching Power Supply 9 by EMI filtering circuit 7, current rectifying and wave filtering circuit 8, and emergency lighting change-over circuit 5 is connected with Switching Power Supply 9, and Switching Power Supply 9 is connected with accumulator 6 by charging circuit 10.Be provided with control relay circuit 11 between emergency light 4 and the emergency lighting change-over circuit 5.Emergency light 4 comprises the LED3 emergency light and before is equipped with the fluorescent light 13 of inverter circuit 12, is provided with change-over switch S3 between LED3 emergency light, inverter circuit 12 and the control relay circuit 11.Emergency lighting change-over circuit 5 comprises the first triode Q1 and the second triode Q2, control relay circuit 11 comprises change-over switch S3, the relay moving contact, normally closed stationary contact 1 and Chang Kai stationary contact 2, the emitter of the first triode Q1 is connected with the positive pole of accumulator 6, the base stage of the first triode Q1 is connected with the collector of the second triode Q2 by first resistance R 1, the collector of the first triode Q1 is connected with the normally closed stationary contact 1 of relay R L1, the collector of the first triode Q1 is connected with the stationary contact 2 of often opening of relay by a switch S 2 simultaneously, the moving contact of relay is connected with the moving contact of change-over switch S3, first stationary contact 2 of change-over switch S3 is connected with the LED3 emergency light by second resistance R 2, second stationary contact 3 of change-over switch S3 be connected with the input end of inverter circuit 12 by the 3rd resistance R 3, accumulator 6 is connected with inverter circuit 12.
The principle of Fig. 4 is done following explanation:
The EMI filtering circuit: the EMI filtering circuit is made up of elements such as C1, L1.Be used for suppressing not influencing this circuit working because of radiation and the caused electromagnetic interference (EMI) of conduction from the outside; Can not cause interference to other electrical equipment in the same environment by the inner high-frequency interferencing signal that produces of this circuit simultaneously, to reach electromagnetic compatibility by radiation and conduction pattern yet.
Switching Power Supply adopts the TNY264P power module, and it belongs to high-level efficiency, the miniwatt inverse-excitation type switch power-supply, and it converts civil power to required DC voltage and charges a battery and provide operating voltage to subsequent conditioning circuit.
The emergency lighting change-over circuit: the DC voltage of Switching Power Supply rectification output charges the battery by D1, R4, R5, and the size of adjusting R5 can be controlled the size of charging current.At this moment, though the conducting of Q2 positively biased, because the Q1 base stage is higher than emitter voltage by the voltage that D2 obtains, so Q1 only carries its collector no-voltage.When the output of civil power sudden power Switching Power Supply no-voltage, but because capacitor C 2 has energy storage function, therefore still positively biased conducting of Q2, its current collection is electronegative potential very, the Q1 base stage lost high level and became electronegative potential this moment, therefore Q1 conducting, the Q1 collector gets, the Q2 base stage gets electric still conducting by D3, R6 from the Q1 collector, continue to keep the Q1 conducting, circuit is in the self-locking duty thus, lights the LED lamp of LED2, LED3 branch road, emergency lighting when being lower than 150V (is 220V for civil power) when civil power or not having civil power.
When the S2 closure, when civil power is arranged, the RL1 adhesive set of relay J, by the Switching Power Supply power supply, LED3 branch road illuminating lamp is bright; During no civil power, the RL1 of relay J discharges and puts " 2 ", is powered by the emergency lighting change-over circuit by accumulator, and the LED3 illuminating lamp is also bright.
Switch S 2 disconnects, and when civil power was arranged, the RL1 adhesive set LED3 branch road illuminating lamp of relay J did not work, and during no civil power, the RL1 of relay J discharges and puts " 2 ", is powered by the emergency lighting change-over circuit by accumulator, and LED3 branch road illuminating lamp is met an urgent need and lighted.
The fluorescent lighting inverter circuit: inverter circuit is made up of elements such as L2, T1, Q3, Q4, C3.This is a half-bridge oscillation circuit, under no civil power situation, and the energising of Q1 collector.When the 1-3 of change-over switch S3 connects, Q3, Q4 base stage by resistance R 3 electric generation vibration, the dc energy of BATTERY is become high-frequency and high-voltage lights fluorescent light and do emergency lighting.When the 1-2 of change-over switch S3 connected, the LED lamp of LED3 branch road was lighted and is done emergency lighting.
