Abstract
The utility model provides a light emitting structure that side income formula is shaded, including optics diaphragm, light -directing structure, reflector plate, backplate and light source, the optics diaphragm sets up in light -directing structure's front, and light -directing structure sets up in the front of reflector plate, and the reflector plate setting is in the front of backplate, and the light source setting is at light -directing structure's side, and lighting direction is towards light -directing structure, and last site or the microcellular structure of being equipped with of light -directing structure is equipped with light guide face in the light -directing structure, thereby the light source reflects through light guide face and gives off light through the optics diaphragm. The utility model discloses set up guiding light face in the light guide plate, light after will reflecting or reflect forms the strip and distributes, and range upon range of through the multilayer light guide plate demonstrates a plurality of controllable and send out the light zone territory on the light emitting area, and it can be strip or massive to send out a light zone territory, and the number of piles of light guide plate is more, and it is more that the controllable that can divide out sends out the light zone territory, and the control area of luminance is just finer and smoother.
Description
Technical field
This utility model relates to the structure of side entrance back, it is adaptable to LCD TV, mobile phone, panel computer, advertising lamp box, flat lamp.
Background technology
Current backlight technology main flow has two kinds, straight-down negative and side entering type, and straight-down negative is the luminous source underface at exiting surface, and side entering type luminous source utilizes light guide plate that light is exported to front at side.
The side entrance back utilizing light guide plate is unable to reach the light emitting control of exiting surface regional area with current technology, what can only provide whole of front goes out light, the performance of product is so limited in some application scenario, owing to the brightness of side entrance back is the same cannot to make local dimming on the picture of background black on LCD TV is applied, the contrast of such picture is just not, make picture clear not, if able to make local luminous that can improve the multiformity of advertisement on advertising lamp box is applied.
Summary of the invention
Technical problem to be solved in the utility model is to provide the ray structure of a kind of side entrance back, it is possible to realize local luminous function, promotes contrast and the harmony of light-emitting area, expands the scope of application of ray structure.
This utility model solves technical problem and be the technical scheme is that the ray structure of a kind of side entrance back, including blooming piece, light guide structure, reflector plate, backboard and light source, described blooming piece is arranged on the front of light guide structure, described light guide structure is arranged on the front of described reflector plate, described reflector plate is arranged on the front of described backboard, described light source is arranged on the side of described light guide structure, and direction of illumination is towards described light guide structure, described light guide structure is provided with site or microcellular structure, light guide surface it is provided with in described light guide structure, described light source is undertaken reflecting by light guide surface thus passing through the luminescence of described blooming piece.
While adopting technique scheme, this utility model can also adopt or combine and adopt technical scheme further below:
Being provided with multiple light guide surface in described light guide structure, light source is presented luminous zone and/or light-emitting block by multiple light guide surfaces on blooming piece.
Described light guide structure includes the light guide plate that multiple stacking is arranged, light guide surface it is each provided with in the plurality of light guide plate, described light guide surface is arranged on the back side of described site or microcellular structure, and described light guide surface cooperatively forms light-emitting zone with described site or microcellular structure.
The light guide surface of the plurality of light guide plate is staggered so that light source presents staggered spaced block luminous zone on blooming piece.
Described light source is LED light source.
Described blooming piece is brightening piece or diffusion sheet.
The beneficial effects of the utility model are: the principle system of edge-type light guide plate utilizes does site or micro structure on light guide plate and entered by luminous source after the luminous reflectance of light guide plate or refraction from front out, realize luminous function, this utility model is provided with light guiding surface in light guide plate, light after reflection or refraction is formed strip distribution, and, stacking by multilamellar light guide plate, light-emitting area presents multiple controllable light-emitting zone, light-emitting zone can be strip or bulk, the number of plies of light guide plate is more many, the controllable light-emitting zone that can branch away is more many, the control area of brightness is just finer and smoother.

Detailed description of the invention
With reference to accompanying drawing.
This utility model includes blooming piece 1, light guide structure 2, reflector plate 4, backboard 5 and light source 3, blooming piece 1 is arranged on the front of light guide structure 2, light guide structure 2 is arranged on the front of reflector plate 4, reflector plate 4 is arranged on the front of backboard 5, light source 3 is arranged on the side of light guide structure 2, and direction of illumination is towards light guide structure 2, light guide structure 2 is provided with site or microcellular structure 7, being provided with light guide surface 6 in light guide structure 2, light source 3 is undertaken reflecting by light guide surface 6 thus passing through blooming piece 1 luminescence.
Being provided with multiple light guide surface 6 in light guide structure 2, light source is presented luminous zone and/or light-emitting block by multiple light guide surfaces 6 on blooming piece 1.
Light guide structure 2 includes the light guide plate that multiple stacking is arranged, light guide surface 6 it is each provided with in multiple light guide plates, light guide surface 6 is arranged on the back side of described site or microcellular structure, and light guide surface cooperatively forms light-emitting zone with described site or microcellular structure.
The light guide surface of multiple light guide plates is staggered, light source is made to present staggered spaced block luminous zone on blooming piece, as shown in Figure 5, more region can be controlled compared with in the structure of monolayer, brilliance control for each region is finer and smoother, can also control each region simultaneously and send the light of different brightness.
Light source 3 can adopt LED.
Blooming piece 1 can adopt brightening piece or diffusion sheet.
