Detailed description：
As shown in 1-accompanying drawing of accompanying drawing 3, the present invention is a kind of backing structure for LED, and described backing structure includes
Bottom surface diffusive reflective film is laid in mounted LED lamp plate 3 in box-like backlight frame 1, the base of frame 2 of backlight frame 1, LED lamp panel 3
4, the position of framework upper port 5 of backlight frame 2 sets optical film group 6, and side is set on the frame side wall 7 of described backlight frame 1
Face diffusive reflective film 8.
Set in described LED lamp panel 3 in multiple LED lamp beads 9, bottom surface diffusive reflective film 4 set with the quantity of LED lamp bead 9 and
The one-to-one opening portion I in position, four frame side walls 7 of backlight frame 1 set side diffusive reflective film 8, described side respectively
Face diffusive reflective film 8 is pasted onto on frame side wall 7.
Heat-conducting glue layer 10 is set between described base of frame 2 and LED lamp panel 3, by heat-conducting glue layer 10 by LED lamp bead 9
The even heat of generation being delivered on base of frame 2 and backlight frame 1 well, plays the purpose fully radiated.Bottom surface is unrestrained anti-
Setting support pad 11 between film 4 and LED lamp panel 3 is penetrated, support pad 11 is covered in base of frame 2, set in support pad 11
Put and the one-to-one opening portion II of the quantity of LED lamp bead 9 and position.Support pad is played a supporting role to bottom surface diffusive reflective film,
So that it is guaranteed that bottom surface diffusive reflective film 4 is reliably covered in support pad 11, the setting of opening portion II so that LED lamp bead 9 not by
Support pad is blocked, so as to effectively work.
Described LED lamp panel 3 is connected by multiple screws 12 with the base of frame 2 of backlight frame 1, side diffusive reflective film 8
Lower end sets kink 13, and kink 13 is fitted in bottom surface diffusive reflective film 4.
The described lower surface of LED lamp panel 3 is set to be set and positioning in multiple locating dowels 14, the base of frame 2 of backlight frame 1
The one-to-one positioning hole of the quantity of post 14 and position, the setting of locating dowel and positioning hole can realize LED lamp panel 3 and framework bottom
The reliable location of position and connection between portion, improve integral installation performance.
When described LED lamp panel 3 is installed in base of frame 2, locating dowel 14 is respectively set to be inserted into a positioning hole
Interior structure.In such manner, it is possible to realize the reliable location of LED lamp panel 3 and base of frame and be connected.
The framework upper port 5 of described backlight frame 2 sets the clamping port 15 of L-type, the edge portion of described optical film group 6
It is set to the structure being pasted onto on clamping port 15.The setting of clamping port, is easy to optical film group 6 in the framework upper end of backlight frame 2
The reliable installation of 5 positions of mouth, improves the performance of whole back-light mechanism.
Light source is all lossy in direct projection, reflection, refracting process, in the case that battle-sight range is certain, reduces reflection and rolls over
Penetrate area to reduce light source transmission loss, so as to realize the effect for improving LED light source utilization rate.
Backing structure of the present invention for LED, specific installation steps are as follows：In the non-cloth lamp face of LED lamp panel
One layer of heat-conducting glue layer is set, and LED lamp panel is fixed in the base of frame of backlight frame by screw, support pad is pasted
In LED lamp panel, the setting of the opening portion II in support pad, can avoid out LDE lamp beads and component in LED lamp panel,
The position of the first-class part of screw, then bottom surface diffusive reflective film is covered in support pad, the opening portion I in the diffusive reflective film of bottom surface
Set, and get out of the way the position of the part such as lamp bead in LED lamp panel, then side diffusive reflective film is covered in the frame of backlight frame again
Optical film, is finally assembled in the framework upper port position of backlight frame, is finally completed assembling by frame side wall inner surfaces.
As the further improvement of such scheme, when bottom surface diffusive reflective film is pasted, it is desirable to by except the lamp bead in LED lamp panel with
Outer position is blocked completely, and bottom surface diffusive reflective film upper surface is flushed with the lamp bead exiting surface of the LED lamp bead in LED lamp panel, on
Lower deviation is controlled in ± 0.2mm, it is ensured that whole backing structure performance.
As the further improvement of such scheme, side diffusive reflective film requires close, seamless when pasting, and prevents because patch
Cover and there is deviation, cause side diffusive reflective film to there is gap, side diffusive reflective film and bottom surface diffusive reflective film with bottom surface diffusive reflective film
The position of contact sets kink, and kink is rolled over 90 degree and is covered in the diffusive reflective film of bottom surface.
Backing structure of the present invention for LED, simple in construction, dependable performance, for existing LED backlight
Light source backlight cavities easily produce the present situation of wasted space, by setting bottom surface diffusive reflective film and side diffusing reflection in backing structure
Film, can realize the purpose that the light source for producing the LED lamp bead in LED lamp panel is reflected, and can effectively improve LED/light source profit
With rate, reduce the loss consumption of light LED/light source, save the energy.
Exemplary description is carried out to the present invention above in conjunction with accompanying drawing, it is clear that concrete implementation of the present invention is not by above-mentioned
The limitation of mode, if the various improvement of inventive concept and technical scheme of the present invention progress are employed, or it is not improved by this
