The sidewall 114 that framework 110 comprises backboard 112 and extends along backboard 112 edge-perpendicular, framework 110 is for carrying and accommodating reflector plate 120, light guide plate 130 and blooming piece 140.Reflector plate 120, light guide plate 130 and blooming piece 140 are sequentially laminated on the backboard 112 of framework 110.
In the present embodiment, framework 110 is chase, is appreciated that in other embodiments, and framework 110 can also be glue frame or frame of plastic, does not make considered critical here.
Light guide plate 130 has incidence surface 132, the exiting surface 134 adjacent with incidence surface 132 and the bottom surface 136 relative with this exiting surface 134.Light-emitting component 150 is arranged at the side of incidence surface 132.
The effect of light guide plate 130 is the scattering directions guiding light, a light is diffused as uniform face light.Particularly, light guide plate 130 utilizes the method for ejection formation that propylene is pressed into ganoid plate, then with there is high reverse--bias and the material of not extinction, diffusion point is stamped in the bottom surface 136 of light guide plate 130 mode of screen painting, when the light that light-emitting component 150 sends is mapped to described diffusion point by incidence surface 132, reverberation toward all angles diffusion, then can be penetrated by the exiting surface 134 of light guide plate 130.Utilize various density, diffusion not of uniform size point, light guide plate 130 uniformly light-emitting can be made.The purposes of reflector plate 120 is the light that bottom surface 136 spills to be reflected back in light guide plate 130, is used for improving the service efficiency of light.
Blooming piece 140 comprises the diffusion sheet 142, the brightening piece that stack gradually, and wherein said brightening piece comprises the first brightening piece 144 and the second brightening piece 146.Be appreciated that in other embodiments, can also as required the quantity of described brightening piece increased or be reduced, not make considered critical here.
In the present embodiment, light-emitting component 150 is multiple LED.Described multiple LED is linearly arranged in the side of the incidence surface 132 of light guide plate 130.Be appreciated that in other embodiments, light-emitting component 150 can also be EL (electroluminescence, EL sheet) or CCFL (Cold CathodeFluorescent Lamp, cathode fluorescent tube).
Optical cement 160 (not shown in figure 1) is coated in light guide plate 130 and blooming piece 140 surface.Particularly, between light guide plate 130, diffusion sheet 142, second brightening piece 146, first brightening piece 144, there is coating optical cement 160 on surface bonded to each other, namely light guide plate 130, diffusion sheet 142, second brightening piece 146, first brightening piece 144 fit into one by optical cement 160, in addition, optical cement 160 is also coated with at bottom surface 136, first brightening piece 144 of light guide plate 130 away from the one side of the second brightening piece 146.First brightening piece 144 away from the one side of the second brightening piece 146 for exterior display device of fitting.
