Description
Art
The present invention relates to lighting technical field, specifically a kind of emergency lighting system for keeping function with end, especially
It is related to and realizes that end keeps the emergency lighting of function by original switch to control and former illuminating line is not made any changes
System, i.e., during the state that switch is in out, emergency light is bright, if switch is in the state of pass, emergency lighting system does not work.
Background technology
At present, traditional emergency lighting system has two classes：
One class is two-wire system, i.e., cannot in emergency lighting circuit, circuit independently of independent arrange outside general illumination system
Install any switch additional, as long as current failure emergency illuminator is to light automatically, the defect of this kind of emergency lighting system is：Cost is held high
Expensive, construction trouble, light fixture cannot be used as general lighting, be used for fire-fighting emergent；
Another kind of is three line line systems, i.e., recognized in illuminating line with the independent mode for arranging a live wire again have a power failure from
And control whether emergency lighting system starts.It is this kind of to answer illuminator light fixture to be made by switch control as ordinary lamp and lantern
With automatic emergency is as emergence lighting lamp during power failure, and the defect of this kind of emergency lighting system is：Need to be in an individually piece fire of arrangement
Line, construction trouble, cost is high, it is crucial that light fixture is powered when switching closing, does not meet safety standard, only special at some
Occasion can be used.
Both the above mode common defects are：Independent wiring is needed, cost is high, construction trouble, it is impossible to realize that last field is kept
Function, i.e., can not realize according to switch status to control whether electric light tool needs to light.And generally switch when closed, card
It is bright now nobody in activity, also avoid the need for emergency lighting (non-fire-fighting requirements), be a kind of in fact if now illuminator starts
Waste.For example, exhibition center, shop etc., after night stops doing business, nobody also avoids the need for emergency lighting in activity.
The content of the invention
To be solved by this invention is, it is necessary to independent wiring, not at times, to have a power failure for above two emergency lighting system
When, just start emergency lighting system in spite of needs, there is provided a kind of answering with end holding function for wasting defect
Anxious illuminator.
The present invention is that one kind controls illuminator without independent wiring, by recognizing original on off state to realize end
Hold the emergency lighting system kept.Differentiate whether switch closes to decide whether to start emergency lighting during power failure.When having electricity, switch
Closure, normal lighting system work, at this moment as having a power failure, just starts emergency lighting.Switch off, normal lighting system is closed
Close, explanation scene need not be illuminated, at this moment do not start emergency lighting if occurring to have a power failure.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of implementation method of the emergency lighting system with end holding function, including switch C1, light-emitting actuating device
C2, light-emitting device C3, closing detecting apparatus C4, energy storage device C5.Alternating current is by switching C1 output ends and light-emitting actuating device
C2 inputs are connected, closing detecting apparatus C4 signal output part connection light-emitting actuating device C2 signal input part, energy storage dress
C5 output end and light-emitting actuating device C2 connections is put, light-emitting actuating device C2 is connected with light-emitting device C3；Exchange passes through switch
C1, is powered to light-emitting actuating device C2, and light-emitting actuating device C2 is controlled by closing detecting apparatus C4, is there is alternating current
Normal conditions, alternating-current switch C1 directly controls the switch of lamp, the situation for having power supply in light-emitting actuating device C2, also supplies electricity to energy storage
Device C5, charges to energy storage device C5.
By the low impedance device C6 in switch front end, directly get access to grid.
The closure of the closing detecting apparatus C4, to control emergency lighting system, realizes that end keeps function.
The closing detecting apparatus C4 is switched on-off by exporting a low-voltage direct to test.
There is a low-impedance device outside the switch C1, the device can be that exchange that is original or installing additional becomes in power network
Depressor, reactor, PTC resistor, and other are to the low-impedance electrical equipment of DC voltage presentation or device.
It is the on-off circuit or DC drive circuit of controllable silicon by the light-emitting actuating device C2, for driving direct current work
The light source of work；The device is made up of the constant flow module of an AC-DC conversion module and DC-DC, and AC-DC is used by model
The constant pressure input circuit of IW1676 decompression driving chip compositions is constituted, and DC-DC constant-current circuits use SY7201 constant current DCDC cores
The circuit of piece composition.
By the closing detecting apparatus C4 control SY7201 control end so that realize emergency lighting system startup and
Close.
The DC voltage of a low pressure is exported by the closing detecting apparatus C4, during switch closure, DC voltage passes through
C1 and low impedance device C6 is switched, loop, driving switch pipe BG2, output control signal is constituted.The control signal is exported to luminous
Drive device C2, light-emitting actuating device C2 drive light-emitting device C3, and emergency lighting system starts.If switched off, switch inspection
Surveying the DC voltage of device C4 one low pressure of output does not have loop, and switching tube BG2 is not turned on, and emergency lighting system does not start.
Low impedance device C6 directly gets access to grid in switch front end；, can be straight when original system switch leading portion has low impedance device
Connect as C6, when such as there is no low impedance device, then install a low impedance device C6 additional in leading portion.
The light-emitting actuating device C2 is connected with light-emitting device C3, puts bright light source.Energy storage device C5 chargings are given simultaneously.
Whether the closing detecting apparatus C4 in the present invention, detection switch closes, according to the situation of switch by by after shaping
Control signal is transmitted to light-emitting actuating device C2, and then controls the startup of emergency lighting system.
Low impedance device C6, mainly when having a power failure, there is provided a low-impedance loop, it is ensured that closing detecting apparatus C4 energy
Detect whether switch closes.
The beneficial effects of the invention are as follows：
The present invention's there is end to keep the emergency lighting system of function, be controlled using the lamp switch of original general lighting
Emergency lighting system processed, is compared with traditional anxious illuminator, without for install emergency lighting system illuminate independent unwrapping wire be can be with
The last field hold mode (i.e. light fixture light fixture when switch opens is lighted, and is not worked when switching and closing) of illumination is realized,
So in all illumination places, when happening suddenly power outage, the uninterrupted of illumination is realized, it is to avoid panic, the thing such as trample
Therefore generation, particularly burst fire-disaster accident (fire, earthquake etc.) cause have a power failure when, greatly increase the escape chance of people.
