Described front upper casing rear end and rear upper casing front end are respectively equipped with and protrude and recessed step, described front upper casing and rear upper casing form described upper casing by the involutory clamping of this concavo-convex step, described drain pan edge is provided with buckle and screw, and described upper casing and drain pan pass through this buckle clamping, and pass through screw fastening.
Described V-shaped rest is at one end formed by connecting by two uncovered hollow plate bodys in bottom, and this V-type support is fixed on described drain pan front end by securing member, and the drain pan relative with described V-type support is provided with V-arrangement louvre.
Described V-shaped rest rear end is provided with limiting plate, screw and battery tray, and described circuit board is fixed on described drain pan by described limiting plate, and by screw fastening, in described battery tray, battery is housed, and battery tray is arranged on described circuit board one side.
Described battery is rechargeable battery, and it is connected with described circuit board.
Described emergency lightening control circuit is included in the power-off starting switch of automatically opening under powering-off state, and described power-off starting switch is connected between described LED lamp plate and battery.
Contribution of the present utility model is, its light light in the time of fire that efficiently solves existing emergency light weakens, and cannot bring into play the problem of good illuminating effect.The LED lamp plate of emergency light of the present utility model is obliquely installed, this mode is effectively adjusted the lighting angle of LED lamp plate, light can cover in the middle position of passageway for fire apparatus, greatly strengthen lamp light intensity, thereby also can play good illuminating effect in the time that breaking out of fire is full of smoke.The lamp housing of this emergency light is semielliptical shape, handsome in appearance.On the drain pan of this emergency light, have louvre, can distribute in time the heat producing in bulb use procedure, extend bulb service life.
