Description
Technical field
The present invention relates to diffuser plate art, refer in particular to a kind of three-in-one optical diffusing plate.
Background technology
Optical diffusing plate is widely used in liquid crystal display, LED illumination and imaging display system, and its major function makes the abundant scattering of incident light, realizes softer, uniform radiation response.
The maximum feature of optical diffusing plate causes very large interference to light, distribution curve flux regardless of original design is how many degree, as long as light is through diffuser plate, it can make beam angle become 160 ~ 176 °, so from the side, there is the sensation of layer mist in the plate face of light fixture, can prove that beam angle preferably proves to 160 ~ 176 ° greatly from this point, the larger illumination of beam angle is lower, some also can produce optical filtering, the wavelength of part cannot be penetrated, cause colour cast, as carried out interference of light process again on surface (such as: frosted, give as security line), transmittance because of the spontaneous phenomenon of geometrical optics low especially, so the base material being used for making diffuser plate should select refractive index more low better, will be lower to the interference of light.
Current optical diffusing plate is generally simple layer structure, and its brittleness is large, and manufacturing easily fragmentation in process, make product stability poor, and when using, all light and translucent effect are not good, optical diffusing plate easily occurs dazzling lamp shadow outward.Therefore, be necessary to improve current optical diffusing plate.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its fundamental purpose is to provide a kind of three-in-one optical diffusing plate, and it effectively can solve that existing optical diffusing plate brittleness is large, stability is bad and the problem that all light and translucent effect are not good.
For achieving the above object, the present invention adopts following technical scheme:
A kind of three-in-one optical diffusing plate, is made up of the raw material of following weight portion: polystyrene 40% ~ 60%, polymethacrylate 30% ~ 50%, benzyl 1% ~ 10%, light diffusing agent 0.1% ~ 0.5%; Three-in-one optical diffusing plate includes from lower to upper folded diffusion layer, bearing course and the structural sheet established successively, the raw material that diffusion layer comprises is polystyrene and light diffusing agent, the raw material that bearing course comprises is polystyrene and polymethacrylate, the raw material that structural sheet comprises is polystyrene, polymethacrylate and benzyl, and structural sheet includes multiple triangular pile body connected side by side, each triangular pile body is by the stacking formation of multiple polygon cylinders.
As a kind of preferred version, described in have polygon cylinder to be regular hexagon cylinder.
As a kind of preferred version, the thickness of described diffusion layer is 0.03mm.
As a kind of preferred version, the thickness of described bearing course is 0.8 ~ 3mm.
The present invention compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
By forming three-in-one diffuser plate by diffusion layer, bearing course and structural sheet, and the optical diffusing plate coordinating the formula of the present invention to make has excellent performance in the performance tests such as absorptivity, bending strength, heat distortion temperature, impact strength, thermal expansivity, penetrance, diffusibleness, colourity, toughness of products is better, there is good stability, and substantially increase colourity, all better, there will not be dazzling lamp shadow phenomenon, the usability of product is better for light and translucent effect.
