Technical field
The utility model belongs to back light source technique field, and in particular to a kind of high-heat-dispersion LED backlight.
Background technology
Backlight is to provide the light source of panel of LCD, with continuing to develop for lcd technology, liquid crystal display
The application field of device particularly colour liquid crystal display device is also constantly being widened, and liquid crystal display is the display device of non-luminescent,
The function of display must be can be only achieved with backlight, the quality of backlight performance can directly affect the imaging matter of liquid crystal display
Amount.
Small-medium size LED backlight selects the design of LED light bar list short side in order to reduce cost, while in order to ensure light
Brightness requirement, LED is relatively concentrated in the layout of short side, and the heat of short side can be caused to raise rapidly when LED is lighted,
If heat can not be distributed by effective approach, LED temperature can be made to exceed the scope used, cause LED luminance to reduce
Shorten with service life, the rise of backlight source temperature can also cause backlight part bad, such as guide-lighting slab warping, optical film material fold
The problems such as.
The content of the invention
It is uniform that goal of the invention of the present utility model is to provide a kind of radiating, it is to avoid the high-heat-dispersion LED backlight of localized hyperthermia
Source.
In order to realize above goal of the invention, the utility model provides a kind of high-heat-dispersion LED backlight, including diffusion barrier,
Light guide plate and reflectance coating, the side of light guide plate, which is provided with the outside of LED light bar, LED light bar, is provided with U-shaped reflecting plate, and the one of reflecting plate
Black double-sided glue is posted in end connection diffusion barrier, other end connection reflectance coating, junction, and the inner side of reflecting plate is provided with raised line, convex
The top surface of bar is connected with lamp bar, and the two sides of raised line form continuous J-type face, reflecting plate with the medial surface of reflecting plate respectively
Lateral surface be provided with N number of J-type heat conduction bar one, one end of the linear of heat conduction bar one extends to the opposite side relative with LED light bar.
As a kind of improvement of the present utility model, the two ends of light guide plate are respectively provided with a heat conduction bar two, the one end of heat conduction bar two
One end of LED light bar is connected, the other end extends to the opposite side relative with LED.
As a kind of improvement of the present utility model, the heat conduction bar one is bonding jumper.
As a kind of improvement of the present utility model, the heat conduction bar two is bonding jumper.
As a kind of improvement of the present utility model, the bottom surface of the light guide plate is printed with the site of grid arrangement.
As a kind of improvement of the present utility model, the heat conduction bar one is aluminum strip or copper bar.
As a kind of improvement of the present utility model, the heat conduction bar two is aluminum strip or copper bar.
The utility model discloses a kind of high-heat-dispersion LED backlight, beneficial effect is that radiating is uniform, it is to avoid localized hyperthermia,
Be conducive to increasing LED life-span, it is to avoid backlight part is bad caused by high temperature.
Brief description of the drawings
Fig. 1 is a kind of structural representation of high-heat-dispersion LED backlight of the utility model.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of high-heat-dispersion LED backlight shown in Fig. 1, including diffusion barrier 1, light guide plate 2 and reflectance coating 3, the one of light guide plate 2

Connection, the two sides of raised line 6 form continuous J-type face with the medial surface of reflecting plate 5 respectively, and the lateral surface of reflecting plate is provided with N number of J
The heat conduction bar 1 of type, one end of the linear of heat conduction bar 1 extends to the opposite side relative with LED light bar 4.The heat conduction bar 1
For bonding jumper, it is preferred that the heat conduction bar 1 is aluminum strip or copper bar.This design can make reflecting plate directly contact LED
Bar, by heat derives, while avoiding blocking the light for injecting light guide plate, heat conduction bar 1 exports heat from reflecting plate, realizes equal
Even radiating, it is to avoid localized hyperthermia.
The two ends of light guide plate 2 are respectively provided with a heat conduction bar 28, and the one end of heat conduction bar 28 connects one end of LED light bar 4, another
End extends to the opposite side relative with LED.The heat conduction bar 28 is bonding jumper, it is preferred that the heat conduction bar two is aluminum strip or copper
Bar.Heat conduction bar two strengthens radiating effect,
The bottom surface of the light guide plate 2 is printed with the site of grid arrangement.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this reality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in of the present utility model
Within protection domain.
