The emergency illuminating lamp is simple in structure and low in cost, realizes automatic switching between the mains supply and a storage battery during normal power supply and power interruption, guarantees continuity of illumination without affecting normal production and operation, and can also be used as an illuminating lamp in emergency evacuation.
Description
Technical field
The utility model belongs to a kind of lighting apparatus field, especially a kind of emergence lighting lamp.
Background technology
Particularly important the producer of illumination or full lucifuge bigger for area, relatively take electricity when adopting conventional lighting, be unfavorable for the saving of the energy.Along with development of science and technology, high-brightness LED lamp integument people use widely in every field, use the structure of the lighting of high-brightness LED lamp pearl to be: to comprise lamp housing, front end at lamp housing is installed reflector, the bottom of each reflector is sleeved on the outer rim of LED lamp pearl, each LED lamp pearl all connects the control circuit of installing in the lamp housing, the light fixture of said structure is saved electric energy than ordinary lamp and lantern under the prerequisite of equal illumination, practicality very, but when the power failure that electric power opens circuit or the equipment short circuit causes occurring, the LED light fixture of above-mentioned power saving still can be affected, and work has been caused very big influence.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, with low cost and can keep the emergence lighting lamp of illumination when having a power failure.
The technical scheme that the utility model is taked is:
A kind of emergence lighting lamp, it is characterized in that: comprise lamp housing, light-emitting diode (LED) module and control circuit, light-emitting diode (LED) module is installed in the front end of lamp housing and is driven by control circuit, described control circuit comprises the transformation module, rectification filtering module and triode switch module, one end of transformation module connects civil power, the other end of transformation module connects an end of rectification filtering module, the other end of rectification filtering module connects light-emitting diode (LED) module by the triode switch module, the triode switch module also connects the battery module of installing in the lamp housing, and the output voltage of described rectification filtering module is greater than the output voltage of battery module.
And described rectification filtering module is made of bridge rectifier and electric capacity.
And the base stage of the triode in the described triode switch module and collector electrode series connection back is connected battery module, the emitter connection light-emitting diode (LED) module of triode.
Advantage of the present utility model and good effect are:

Description of drawings
Fig. 1 is a block diagram of the present utility model;
Fig. 2 is a schematic diagram of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection range of the present utility model with following embodiment.
A kind of emergence lighting lamp, shown in Fig. 1～2, innovation of the present utility model is: comprise lamp housing, light-emitting diode (LED) module and control circuit, light-emitting diode (LED) module is installed in the front end of lamp housing and is driven by control circuit, this control circuit comprises transformation module TA, rectification filtering module 1 and triode switch module 2, one end of transformation module connects civil power, the other end of transformation module connects an end of rectification filtering module, the other end of rectification filtering module connects light-emitting diode (LED) module by the triode switch module, the triode switch module also connects the battery module E that installs in the lamp housing, and the output voltage of rectification filtering module is greater than the output voltage of battery module.
In the present embodiment, rectification filtering module is made of bridge rectifier and capacitor C 1, be connected battery module after the base stage B of the triode in the triode switch module and the collector electrode C series connection, the emitter E of triode connects light-emitting diode (LED) module, and light-emitting diode (LED) module adopts the LED lamp pearl of a plurality of low-voltage high brightness formation in parallel.
Operation principle of the present utility model is:
K1 and K2 close a switch, mains-supplied, input to rectification filtering module after the civil power process transformation module TA step-down, this moment since the output voltage of rectification filtering module greater than the output voltage of battery module, diode D conducting, light-emitting diode (LED) module are by mains-supplied, because transistor emitter E voltage is lower than base stage B voltage, therefore triode ends, and battery module E turn-offs.
When civil power cuts off the power supply (in the time of also can being K switch 1 unlatching), the emitter E voltage of triode is higher than base stage B voltage, the triode conducting, battery module E powers to light-emitting diode (LED) module, when the city power recovery (K switch 1 is closed back), triode ends, and light-emitting diode (LED) module recovers mains-supplied again.
The utility model is simple in structure, with low cost, and when normal power supply and power failure, automatic switchover civil power and storage battery have guaranteed the continuity of throwing light on, and can not influence normal production work, the lighting when also can be used as emergency evacuation.
