Description

A kind of emergency lighting system that there is end and keep function

Art

The utility model relates to lighting technical field, specifically a kind of emergency lighting system that there is end and keep function, particularly relate to and control and do not make any changes to former illuminating line to realize the emergency lighting system of end maintenance function by original switch, namely switch be in out state time, 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, namely emergency lighting circuit is arranged separately outward independent of general illumination system, any switch cannot be installed additional in circuit, as long as namely current failure emergency illuminator is lighted automatically, the defect of this kind of emergency lighting system is: involve great expense, construction trouble, light fixture as general lighting use, cannot be used for fire-fighting emergent;

Another kind of is three line line systems, namely in illuminating line, arranges that the mode of a live wire identifies power failure thus whether control emergency lighting system starts with independent again.This kind of illuminator light fixture of answering can use as ordinary lamp and lantern by switch control rule, during power failure, automatic emergency is as emergence lighting lamp, the defect of this kind of emergency lighting system is: need arrange a live wire separately, construction trouble, cost is high, it is crucial that light fixture is charged when switch cuts out, do not meet safety standard, only can use at some special occasions.

Above two kinds of mode common defects are: need independent wiring, and cost is high, construction trouble, can not realizing last field and keep function, namely can not realizing controlling electric light tool the need of lighting according to switch status.And switch, when cutting out, proves now unmanned in activity usually, also just not needing emergency lighting (non-fire-fighting requirements), if now illuminator starts, is a kind of waste in fact.Such as, exhibition center, shop etc., after stopping doing business night, unmanned in activity, also just do not need emergency lighting.

Summary of the invention

To be solved in the utility model is for above-mentioned two kinds of emergency lighting systems, needs independent wiring, not at times, during power failure, no matter the need of just starting emergency lighting system, wasting defect, provides a kind of emergency lighting system having end and keep function.

The utility model is a kind of without the need to independent wiring, by identifying that original on off state controls lighting thus realizes the emergency lighting system of end maintenance.Differentiate during power failure that whether switch is closed to determine whether starting emergency lighting.When having electricity, switch closes, normal lighting system work, at this moment as having a power failure, just starts emergency lighting.Switch disconnects, and normal lighting system is closed, and explanation scene does not need illumination, and at this moment having a power failure as occurred just does not start emergency lighting.

The utility model solves the technical scheme that its technical problem adopts:

There is the emergency lighting system that end keeps function, comprise switch C1, light-emitting actuating device C2, light-emitting device C3, closing detecting apparatus C4, energy storage device C5.Alternating current is connected with light-emitting actuating device C2 input by switch C1 output, the signal output part of closing detecting apparatus C4 connects the signal input part of light-emitting actuating device C2, the output of energy storage device C5 is connected with light-emitting actuating device C2, and light-emitting actuating device C2 is connected with light-emitting device C3; Exchange by switch C1, power to light-emitting actuating device C2, and light-emitting actuating device C2 is subject to the control of closing detecting apparatus C4, there are being the normal conditions of alternating current, alternating-current switch C1 directly controls the switch of lamp, there is the situation of power supply at light-emitting actuating device C2, also power to energy storage device C5, energy storage device C5 is charged.

By described Low ESR device C6 in switch front end, directly get access to grid.

By the control end of described closing detecting apparatus C4 control SY7201, thus realize startup and the closedown of emergency lighting system.

Exported the direct voltage of a low pressure by described closing detecting apparatus C4, when switch closes, direct voltage, by switch C1 and Low ESR device C6, forms loop, driving switch pipe BG2, exports control signal.This control signal exports to light-emitting actuating device C2, and light-emitting actuating device C2 drives light-emitting device C3, and emergency lighting system starts.If switch disconnects, the direct voltage that closing detecting apparatus C4 exports a low pressure does not have loop, and switching tube BG2 not conducting, emergency lighting system does not start.

Low ESR device C6, in switch front end, directly gets access to grid; When original system switch leading portion has Low ESR device, can directly as C6, during as there is no a Low ESR device, then install a Low ESR device C6 additional at leading portion.

Described light-emitting actuating device C2 is connected with light-emitting device C3, some bright light source.Charge to energy storage device C5 simultaneously.

Closing detecting apparatus C4 in the utility model, whether sense switch closes, and passes to light-emitting actuating device C2 according to the control signal after the situation of switch just shaping, and then controls the startup of emergency lighting system.

Low ESR device C6, mainly when having a power failure, provides a low-impedance loop, ensures that closing detecting apparatus C4 can detect whether switch closes.

The beneficial effects of the utility model are:

The emergency lighting system that there is end and keep function of the present utility model, use the lamp switch of original general lighting to control emergency lighting system, compare with the anxious illuminator of tradition, the last field hold mode that namely can realize throwing light on without the need to the independent unwrapping wire that throws light on for installation emergency lighting system (namely light by light fixture light fixture when switch opens, do not work when switch cuts out), like this in all illumination places, when happening suddenly power outage, achieve the uninterrupted of illumination, avoid fear, the generation of accident such as to trample, particularly burst fire-disaster accident (fire, earthquake etc.) when causing power failure, greatly increase the escape chance of people.

Accompanying drawing illustrates:

Fig. 1 is the block diagram having end and keep the emergency lighting system of function of the present utility model.

Fig. 2 is the circuit theory diagrams of light-emitting actuating device of the present utility model.
