Whether components are in the detection function of normal condition；Avoid and cavity installation function key switch is set on light-passing board.
Such scheme still suffers from weak point, when the condition of a disaster occurs, what the electric wire that is connected with emergency light sometimes will not be suddenly
Situation about damaging occurs, so now the stand-by power supply in emergency light will not start, emergency light would not be also illuminated
Operation, emergency light can not in advance be opened in the condition of a disaster generation primary stage, just open without waiting for after damaged wire, open in advance
Emergency light after opening extinguishes the seamless connection for foring light with follow-up interior illumination fixture, will not be after lighting apparatus extinguishing suddenly
Into in dark, it is necessary to wait several seconds emergency light just to illuminate.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of intelligent emergent lamp, solve
When the condition of a disasters such as fire occur, interior illumination fixture extinguishes the problem of being opened with emergency light in this period without illumination.
To achieve the above object, the utility model provides following technical scheme：
