A kind of LED backlight
Liquid crystal display field is the utility model is related to, more particularly to a kind of LED backlight.
LED is with many merits such as thin, power saving, radiationless, at monitor, TV, Pad, mobile and some other family
Outer advertisement machine is commercially available extensive use.Liquid crystal display device in the market is mainly made up of two parts：Liquid crystal panel
And backlight module.Because liquid crystal display panel does not light in itself, so needing normally to show shadow by the light of backlight module
Picture；Therefore backlight module turns into an indispensable part of liquid crystal display.But when LED works long hours, by light source
The heat distributed can make the temperature at light source too high, if lamp bead works long hours at high temperature, can not only reduce the use of light source
Life-span, and the life-span of whole backlight module and LED can be reduced；Meanwhile if temperature is too high, it on the one hand may cause light source
Neighbouring light guide plate expansion；On the other hand when backlight module is assembled on LED, close to the liquid of light source on liquid crystal display panel
Brilliant molecule also easily fails, and causes image poor display, and the heat at light source can also influence LED display effect, such as picture
Rock or flash.
Backlight module on the market mainly has two kinds of forms now：Side entrance back module and down straight aphototropism mode set, side
Enter formula backlight module to be made up of following part：Backboard, light guide plate, light source and blooming piece；And backboard is typically by same
Material forms for example：Iron plate, aluminium sheet and Plastic material；If backboard is done using iron plate, then the radiating effect of the backlight
It is bad, and then the life-span of lamp bead and the life-span of complete machine can be influenceed；If directly all done using aluminium sheet, then this will be unfavorable for
The cost control of backlight；If using the backboard of plastic material, although cost effectively can control radiating effect more to pay no attention to
Think, can accelerate to reduce the life-span of lamp bead, influence the service life of complete machine.
Utility model content
The utility model can carry mainly solving the technical problems that provide a kind of LCD backlight module radiator structure significantly
The radiating effect of LED light bar is risen, and is directed to the LCM of high brightness, the service life of backlight can also be improved.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of LED backlight is provided,
Reflector plate including light guide plate, below light guide plate, FPC plates, interior glue frame and U-shaped outer aluminium frame with LED light bar, its feature
It is：The FPC plates are fixed on the light inputting end side of light guide plate；The interior glue frame is located at the inside of U-shaped outer aluminium frame, the FPC
Mounted LED lamp bar above plate, U-shaped outer aluminium frame is fixed in lower section by bond plies, while is radiated by U-shaped outer aluminium frame.
Preferably, the interior glue frame is further opened with locating slot, the LED lamp bars peace at bond plies installing plate
Loaded in locating slot.
Preferably, the U-shaped outer aluminium frame is regular polygon in the horizontal direction.
Preferably, the interior glue frame and U-shaped outer aluminium frame are integrally formed.
The beneficial effects of the utility model are：Heat caused by LED can be transmitted to the good FPC plates of thermal conductivity first
On, FPC plates conduct heat on radiation aluminium frame again;Finally, the aluminium sheet with larger radiating surface that heat passes through heat-dissipating aluminium plate
Body is dispersed into air, effectively reduces the operating temperature of LED, so as to improve the service life of LED backlight, together
When U-shaped aluminium section bar parcel in glue frame be integrally formed the anti-shake performance for improving backlight, save production cost.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the preferred embodiment of the utility model LED backlight one；
The mark of each part is as follows in accompanying drawing：1st, light guide plate, 2, reflector plate, 3, FPC plates, 4, LED light bar, 5, interior glue frame,
6th, U-shaped outer aluminium frame, 7, bond plies.
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Referring to Fig. 1, the utility model embodiment includes：Light guide plate 1, the reflector plate 2 below light guide plate, have
FPC plates 3, interior glue frame 5 and the U-shaped outer aluminium frame 6 of LED light bar 4, wherein, FPC plates 3 are fixed on the light inputting end side of light guide plate 1；It is interior
Glue frame 4 is located at the inside of U-shaped outer aluminium frame 5, and the top mounted LED lamp bar 4 of FPC plates 3, lower section is fixed on U-shaped by bond plies 7
Outer aluminium frame 5, while radiated by U-shaped outer aluminium frame 5.
Aluminium section bar bottom plate is further opened with locating slot at the installing plate of bond plies 7, and the LED light bar 4 is installed on fixed
In the groove of position.Interior glue frame 5 and U-shaped outer aluminium frame 6 are integrally formed.It is good that heat caused by LED light bar 4 can be transmitted to thermal conductivity first
On FPC plates 3, FPC plates 3 conduct heat on radiation aluminium frame again;Finally, heat has larger radiating surface by heat-dissipating aluminium plate
Aluminium sheet body be dispersed into air, the operating temperature of LED light bar 4 is effectively reduced, so as to improve the use of LED backlight
In order to further improve the stability of heat-conducting type back light, interior glue frame 5 by the U-shaped outer integrated through injection molding of aluminium frame 6 into
Type.FPC plates 3 are connected with bond plies 7, and bond plies 7 are connected with the U-shaped outer bottom surface of aluminium frame 6, and LED light bar 3 is arranged at
The top of FPC plates 3, replace punching press metal plate to make LCM bottom plates using aluminium section bar, due to the heat-sinking capability of aluminium section bar to be far above it is zinc-plated
Plate or iron plate, therefore greatly improve radiating effect.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
