As shown in figure 3, be straight-down negative LED light source module provided by the utility model, including LED light source 22 and it is provide with described
The encapsulating structure of LED light source, encapsulating structure include transparent base 21 and are simultaneously the anti-of concave structure towards the LED light source
Unit 23 is penetrated, LED light source 22 is located on transparent base 21.Reflector element 23 forms an enclosed construction, cover with transparent base 21
Arranged on LED light source 22.When LED light source 22 is located at the focus of reflector element 23, reflected light will be upwardly into optics in directional light
Film group and liquid crystal mould are fast.Fig. 3 shows an independent direct-type backlight LED light source standard module.Specifically, when concave surface is tied
When structure is arc surface, focal length is the half of radius of curvature, and according to geometric optics, when light source is located at focus, paraxial rays is with flat
Row light mode reflects, and far-off axle light rays will also be reflected with low-angle, therefore light-emitting angle is straight compared to LED light source in the prior art
The light-emitting angle tool of sending and receiving light improves significantly；And when concave structure is parabola face, according to geometric optics, positioned at focus
The light that is sent of light source with parallel light reflection.The point light source of the structure, before its light enters diffuser plate, reflector element 23 is
Pre- Homogenization Treatments first have been carried out to LED light source, therefore, the diffuser plate for the low haze that can arrange in pairs or groups, and then improve light extraction benefit.
Further, since light source has been in after reflection flat shape light, the ratio that light is spread to big visual angle is reduced, positive angle can be improved
Luminous intensity.Therefore the design of the utility model can improve the brightness of display, and reach energy saving effect.
As shown in figure 4, be the LED light source module of another structure, by LED light source 22, transparent base 21, supporting framework 3,
Reflector element 4 is formed.Wherein transparent base 21, supporting framework 3, reflector element 4 form an envelope for covering at LED light source 22
Close structure.Wherein transparent base, supporting framework can be integrally formed, and reflector element can be the Fresnel reflection shown in Fig. 4
The reflecting surface of mirror, that is, Fresnel structure, the reflecting surface can be by realizing in Fresnel structure plating metal on surface such as silver, aluminium.Its
Function is, the directional light of reflection can uniform irradiation cover area in total.
Light source standard module is done based on the utility model, spliced arrangement can be used, seamless covers whole display
Area required for device, such as Fig. 5.Under such design, display designer is not required to redesign light source again, only needs to use
LED light source standard module, rational joint is done according to display sizes.Also, since LED module has been covered with whole display surface
Product, therefore, extra reflecting piece is not required with the backlight module of this utility model.
The base material of the utility model can be transparent base, which can be specifically that PET, PC, PMMA etc. are transparent
Base material, preferably PET class flexible and transparent base materials.Groove can be set over the transparent substrate, filling transparent conductive material in it,
For being powered to LED light source.The transparent conductive material, can be selected from ITO, nano silver or graphene etc..
It is contemplated that the light that LED light source is sent is reflexed on transparent base after reflecting curved surface reflects in directional light, reflection
A part of light returned will be stopped be subject to LED light source, cause the optical effect of straight-down negative LED light source module cannot reach most
It is good.To make straight-down negative LED light source module that there is more preferably optical appearance the utility model in the surface of transparent base and/or inside
Processing is diffused, there is provided diffusion structure.Lid diffusion structure can specifically use net-point printing, doping diffusion particle, surface
The modes such as micro-structure are formed.
Diffusion structure can be specifically arranged on to the inside of transparent base, directional light expands after diffusion structure is reached
Dissipate, a part of light will scatter to the region blocked by LED light source, so as to make up the missing of the zonal ray.
Diffusion structure can also be arranged on the surface of transparent base, directional light occurs when inciding diffusing structure
Scattering, light are distributed to all angles, are partly into the region stopped by LED light source, so as to make up lacking for the zonal ray
Lose.
It should be noted that in the utility model preferred solution, to ensure dissipating at most directional light and LED light source
Needs are penetrated, diffusion structure is only set on the periphery of the upright projection of transparent base in LED light source, its peripheral extent is determined with energy
Enough make up and be limited by the light that LED light source stops.
As shown in fig. 6, a kind of backlight module provided for the utility model based on above-mentioned straight-down negative LED light source module
Embodiment.Being cascading in the LED light source module of the splicing has diffuser plate, diffusion barrier and brightness enhancement film.Compared to existing
There is structure, it no longer needs reflecting piece.
The utility model further includes a kind of display panel, it includes the backlight module of said structure.
It should be noted that embodiment is only the explanation to technical solutions of the utility model, should not incite somebody to action
It is interpreted as the restriction to technical solutions of the utility model, any to use the utility model in essence utility model content and only work office
What portion changed, it should fall into the scope of protection of the utility model.
