The utility model content
The utility model has proposed a kind of emergency light of using the LED-backlit source for remedying the deficiencies in the prior art, is illuminating source with the LED-backlit source, and the life-span, long electricity consumption was few.
For achieving the above object, the utility model has adopted following technical scheme:
Use the emergency light in LED-backlit source, comprise handle, shell, LED-backlit source, power supply control module, power supply input port and battery, handle is located at cover top portion, battery is located in the shell, power supply control module and power output are located at the shell side, and the LED-backlit source is a writing board shape, and the LED-backlit source is located on the shell, LED-backlit source and battery electrically connect with power supply control module respectively, and power supply control module then links to each other with civil power by the power supply input port.
As improvement of the technical scheme, the LED-backlit source has layer structure, comprise led light source, optics LGP, blooming piece and support, led light source and power supply control module electrically connect, led light source, optics LGP, blooming piece all are located in the support, led light source is located at the side of optics LGP and its light-emitting area side over against the optics LGP, and the upper and lower surface of LGP all is provided with blooming piece.
As improvement of the technical scheme, led light source comprises a plurality of LED that arrange being aligned, and the light-emitting area of LED is over against the side of optics LGP.
As improvement of the technical scheme, support comprises face shield, substrate and frame, and led light source is installed on the side of frame, and optics LGP, blooming piece all are sheathed in the frame, face shield cooperates with substrate to be established the frame folder wherein, then is provided with the window with optics LGP coupling on the face shield.
As improvement of the technical scheme, LGP cooperates the one side of the window on the face shield to be provided with three layers of blooming piece, and another side is provided with one deck blooming piece.
In mains-supplied just often, power supply control module is monitored battery tension, and when battery tension was lower than 6.9V, civil power was to charge in batteries; Along with the charging interval increases, battery tension is during greater than reference voltage 6.9V, and power supply control module disconnects the charge circuit of civil power to battery.When mains failure, power supply control module automaticallyes switch and by battery the LED power supply is powered, and makes the LED-backlit source luminous.
Compare with prior art, the beneficial effects of the utility model are:
Adopt the new LED backlight to replace traditional miniature bulb as illuminating source, caloric value is lower, and light intensity is bigger, longer service life, and power consumption has only 1/6 of traditional miniature bulb, and all devices all meet environmental protection standard.
