Description
Technical field
The present invention relates to field of light fittings, specifically disclose a kind of method of work of emergency light.
Background technology
When there is major accident, fleeing for life from staircase, people are often safest withdraws path.But because often have a power failure when major accident occurs, and staircase is general all more dim, is unfavorable for that people withdraw fast.Be arranged on now the general all dim lights of emergency light in staircase, institute's range of exposures is very fuzzy, for the people had defective vision, cannot see stair clearly, easily cause and get injured by a fall.And present emergency light and corridor lamp are all provided separately substantially, the wiring of first floor and installation are increased, and is unfavorable for line upkeep.
Summary of the invention
The invention is intended to the method for work that a kind of emergency light is provided, be separated from each other to arrange and cause circuit to increase to solve existing corridor lamp and emergency light, install complicated and safeguard problem not easily.
The method of work of the emergency light in this programme, comprises the following steps:
(1) when the alternating current source provided when civil power normally works, controlled by sound and light lighting circuit works, photo resistance receiving optical signals, time light is strong, photo resistance presents low resistive state, makes the signal flowing to time-base integrated circuit from photo resistance be high level, makes time-base integrated circuit output low level, the thyristor triggerless switch off current be connected with time-base integrated circuit, the bulb be connected with thyristor does not work;
(2) when there being huge sound of movement sound in staircase, pick-up obtains acoustic signals, there is operating current conducting in the base stage of the first triode of NPN type, the collector potential of the first triode declines rapidly, and the first diode becomes cut-off from conducting, photo resistance and the 4th electric resistance partial pressure, photo resistance is inputted into the level in time-base integrated circuit below setting voltage, the output of time-base integrated circuit exports high level, and thyristor is triggered conducting, and bulb is lit;
(3) while time-base integrated circuit exports high level, time base integrated electric inside amplifier tube cut-off, 7th pin of time-base integrated circuit is unsettled by internal circuit, thus the blockade relieved the second electrochemical capacitor, so alternating current source cathode voltage is charged to the second electrochemical capacitor by the 5th resistance, the level of the 6th pin of time-base integrated circuit is constantly raised;
(4) when the 6th pin level of time-base integrated circuit reaches setting voltage, transient state terminates, and controlled by sound and light lighting circuit returns to originally stable state, and the tripod of time-base integrated circuit is still low level, thyristor automatically shuts down when alternating current zero passage, and bulb extinguishes; Meanwhile, the discharge tube conducting of time-base integrated circuit inside, the 7th pin output low level of time-base integrated circuit, the electric charge stored in the second electrochemical capacitor is by the 7th pin electric discharge of time-base integrated circuit, and whole controlled by sound and light lighting circuit resets;
(5) charging circuit is first charge in batteries by constant-current charging circuit when the work of controlled by sound and light lighting circuit by the transformer that is connected with alternating current source, when battery voltage detection circuit detects that the voltage of storage battery reaches predetermined value, trickle charging circuit starts charge in batteries, after charging complete, charging circuit quits work;
(6) when occurring emergency, when the alternating current source that civil power provides quits work, the electromagnet be connected with controlled by sound and light lighting circuit loses magnetism, to be adsorbed by electromagnet in charging circuit and the relay disconnected is communicated with, make the loop conducting that storage battery, the 12 resistance, spare bulb and relay connect into, spare bulb is lit;
(7) when alternating current source is resumed work, the switch on relay is again energized the electromagnet producing magnetic and adsorbs and the loop be connected with relay is disconnected, and spare bulb extinguishes.
Operation principle and beneficial effect:
Photo resistance makes thyristor triggerless electric current when light is strong and turns off, and the bulb be connected with thyristor does not work, and avoids bright light waste electric energy by day.
When there being huge sound of movement sound in staircase, pick-up obtains acoustic signals, and by time-base integrated circuit, thyristor is triggered conducting, bulb is lit.Automatically shut down when time-base integrated circuit makes thyristor in alternating current zero passage after a period of time, bulb extinguishes.Can be lighted by sound and extinguish bulb, bulb is just lit when needed, avoiding wasting electric energy.
Charging circuit connects alternating current source when the work of controlled by sound and light lighting circuit by transformer and directly charges, and automatically stops charging after charging complete.When occurring emergency, when mains failure, the electromagnet be connected with controlled by sound and light lighting circuit loses magnetism, and is adsorbed and the relay disconnected is communicated with by electromagnet, and make the loop conducting that spare bulb and relay connect into, spare bulb is lit.Be convenient for people to from staircase by time can have and throw light on clearly, be convenient for people to the stair can seeing underfooting clearly, avoid meeting accident, accelerate to withdraw speed.
The present invention makes corridor lamp and emergency light be joined to one another, installation circuit is reduced, install easy and easy to maintenance.
Further, when constant-current charging circuit charges to storage battery, because battery tension is lower, second triode of the NPN type be connected with storage battery ends, 3rd triode obtains positively biased and conducting by the 7th resistance, alternating current source is by the 3rd triode, the 4th triode of NPN type and the 9th resistance to charge in batteries, and the first light-emitting diode is lighted simultaneously.Conveniently carry out large current charge to storage battery rapidly by constant-current charging circuit, the first light-emitting diode provides constant current reference voltage to double as charging instruction.
Further, in the charging process of constant-current charging circuit to storage battery, battery tension rises gradually, when the predetermined value that the second adjustable resistance risen in battery voltage detection circuit regulates, second triode ON, 3rd triode cut-off, the first light-emitting diode extinguishes, and storage battery proceeds to trickle charge automatically.Carrying out large current charge, transferring when storage battery will be full of to carry out trickle charge to storage battery, conveniently preserve battery capacity.
Further, the second light-emitting diode is used as the indicator light of trickle charging circuit.When trickle charge, the second light-emitting diode is lighted, and after charging terminates, the second light-emitting diode extinguishes, and reminds charging circuit to quit work.
Further, pick-up obtains voice signal by the spherical shell be close to it.Facilitate pick-up more clearly to obtain voice signal, improve the sensitivity of emergency light.
