Description
Technical field
The utility model relates to the electronic product field, particularly a kind of emergency lighting device.
Background technology
The progressively raising that Along with people's requires work living environment, intelligent building obtain more and more people's concern, and a series of intelligentized design makes building have safe, convenient, efficient, energy-conservation characteristics.Illuminator is an indispensable part in the intelligent building, and when illuminating lamp broke down, adopting emergency light to replace original illuminating lamp usually was that corridor, staircase provide illumination.Certainly room lighting also is like this; When the illuminating lamp of normal use breaks down; Because flashlight can only use as temporary lighting, the light is dusky for it, and long-term use is unfavorable to eyesight; Candle is because not enough environmental protection is also eliminated by people gradually, and therefore indoor emergency lighting also uses emergency light to carry out usually.But common emergency light also is when illuminating lamp breaks down, and the mains switch that the user opens emergency light voluntarily could use.But the fault of illuminating lamp is the moment generation normally, if the position that this moment, emergency light was placed is comparatively hidden, then can not throw light in time, life is affected, but also can have potential safety hazard.
Summary of the invention
The technical problem that the utility model solves provides a kind of when the general lighting lamp failure, can trigger the lighting device that plays the emergency lighting effect automatically.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is following.
A kind of emergency lighting device comprises power supply, current-limiting resistance and general lighting lamp, and said power supply and current-limiting resistance and general lighting lamp constitute lighting loop; Also be provided with rectifier bridge in the said lighting loop, the two ends parallel connection of rectifier bridge is provided with the standby lighting branch road; Said standby lighting branch road comprises standby lighting lamp, controllable silicon, triode, second resistance, the 3rd resistance and the 4th resistance; The branch road parallel connection that wherein is connected in series by controllable silicon and standby lighting lamp is arranged on the output of rectifier bridge, and the branch road parallel connection that is connected in series by second resistance and triode is arranged on the output of rectifier bridge; The base stage of triode is connected between current-limiting resistance and the general lighting lamp through the 3rd resistance, and the collector electrode of triode is connected with the 4th resistance with second resistance respectively, and the emitter of triode connects an output of rectifier bridge; The other end of the 4th resistance is connected with the silicon controlled trigger end.
The improvement of the utility model is: the color of said standby lighting lamp is different with the color of general lighting lamp.
Owing to adopted above technical scheme, the technological progress that the utility model is obtained is following:
The subsequent use emergency light that the utility model is provided with; When the general lighting lamp breaks down; Utilize the controlled trigger theory of triode and silicon controlled that subsequent use emergency light is lighted,, realized emergency light moment automatic shifting function for the user carries out emergency lighting; Satisfy user's demand, can not have any impact life and work.Subsequent use emergency light adopts and general lighting lamp various colors, not only plays the effect of differentiation, the more important thing is can remind constantly the user be subsequent use emergency light in illumination, need as early as possible to the place under repair of general lighting lamp.
Description of drawings
Fig. 1 is the electric connecting relation figure of the utility model.
Embodiment
To combine specific embodiment and accompanying drawing below, the utility model will be further elaborated.
A kind of emergency lighting device, its electrical connection diagram is as shown in Figure 1.Comprise power supply, rectifier bridge, normal illumination branch road and standby lighting branch road, AC power is output dc voltage after the rectifier bridge rectification, is normal illumination branch road and the power supply of standby lighting branch road.The normal illumination branch road comprises current-limiting resistance R1 and general lighting lamp L1, is connected in parallel on the output of rectifier bridge after current-limiting resistance R1 and general lighting lamp L1 are connected in series.
The standby lighting branch road comprises standby lighting lamp L2, controllable silicon KP, triode T1, second resistance R 2, the 3rd resistance R 3 and the 4th resistance R 4.The branch road parallel connection that wherein is connected in series by controllable silicon KP and standby lighting lamp L2 is arranged on the output of rectifier bridge, and the branch road parallel connection that is connected in series by second resistance R 2 and triode T1 is arranged on the output of rectifier bridge; The base stage of triode T1 is connected between current-limiting resistance R1 and the general lighting lamp L1 through the 3rd resistance R 3, and the collector electrode of triode T1 is connected with the 4th resistance R 4 with second resistance R 2 respectively, and the emitter of triode T1 connects an output of rectifier bridge; The other end of the 4th resistance R 4 is connected with the trigger end of controllable silicon KP.
The operation principle of the utility model is described below:
During normal illumination, general lighting lamp L1 lights.At this moment, because the voltage of triode T1 collector electrode is higher than the voltage of triode T1 base stage, so during general lighting lamp L1 normal illumination, not conducting of triode T1.Accordingly, the trigger end of controllable silicon KP is not owing to there being triggering signal to be in not on-state, and standby lighting lamp L2 does not light.
When general lighting lamp L1 fault; The voltage of triode T1 base stage is higher than the voltage of triode T1 collector electrode; Triode T1 conducting this moment, the collector electrode of triode T1 has electric current output, and the trigger end of the 4 couples of controllable silicon KP of the 4th resistance R that flow through triggers; Make controllable silicon KP conducting, standby lighting lamp L2 lights.
The color of general lighting lamp L1 is a white in the utility model, and the color of standby lighting lamp L2 is red, and the color of standby lighting lamp L2 is different with the color of general lighting lamp L1.When general lighting lamp L1 fault, red standby lighting lamp L2 lights, and reminds user's general lighting lamp L1 fault, maintenance as early as possible.
One of circuit series connection at main illuminator detects resistance, when illuminating lamp is in proper working order, flows through the voltage drop that this resistance produces 1V, and the detection open circuit has been designed in the back; There is not voltage when detecting; Promptly know the information that main illuminator damages, start stand-by lamp work immediately, stand-by lamp is used red incandescent lamp; Just know when seeing that red light is bright that so main illuminator damages, please the electrician in time repair main illuminator in second day.After the repairing, circuit recovers normal illumination condition automatically.
