Description

Surface diffusion structure of optical diffusion film

Technical Field

The utility model belongs to the technical field of the optics diffusion barrier, especially, relate to an optics diffusion barrier surface diffusion structure.

Background

With the development of society, the living standard of people is improved, the awareness of environmental protection and energy conservation is enhanced, and the requirements on various materials are higher and higher. At present, the diffusion film (plate) of the accessory materials such as the lighting display screen of the lamp and the like mainly achieves the effect of uniform light and uniform light (namely diffusion) by adding diffusion particles.

The diffusion film surface microstructure on the market is a common frosted structure, the microstructure is designed into triangular pyramids and triangular prism shapes with different sizes and depths, the length d of the structure is set to be 0.05-2.0mm, and the depth is 0.2 times of the diameter d, the diffusion plate of the structure does not have diffusion, acrylic resin microspheres with different sizes are generally coated on the surface of the diffusion film or diffusion particles with spherical structures are added by a diffusant to play a role in diffusion, but the light installation effect of the whole diffusion film can be reduced along with the increase of the diffusion particles.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a duplicate the structure on the diffusion barrier, can reach the even effect of light of certain homogeneous light equally, can effectual increase light efficiency, reduce the interpolation proportion of diffusion particle, not only reduce cost, environmental protection and energy saving's optics diffusion barrier surface diffusion structure moreover.

The utility model is achieved by the following concrete technical means:

a plurality of diffusion grooves are arranged on the surface of a diffusion film body, and the diffusion grooves are hemispherical, semi-ellipsoidal or short cylindrical.

Further, the thickness of the diffusion film body is 0.5-2 mm.

Furthermore, the diameter of the diffusion groove is 0.5-2mm, and the depth is 0.4-0.6 times of the diameter.

Furthermore, a plurality of diffusion grooves are arranged on the upper surface and the lower surface of the diffusion film body.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a shape of arranging on the diffusion barrier surface is hemispherical or semiellipsoid form or short cylindric diffusion tank, can reach the effect of the even light of certain homogeneous light equally, can effectual increase light efficiency, reduces the interpolation proportion of diffusion particle, not only reduce cost, environmental protection and energy saving moreover.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Examples

A surface diffusion structure of an optical diffusion film is disclosed, as shown in figures 1-3, a plurality of diffusion grooves 2 are arranged on the surface of a diffusion film body 1, and the shape of the diffusion grooves 2 is hemispherical, semi-ellipsoidal or short cylindrical.

Wherein, the thickness of the diffusion film body 1 is 0.5-2 mm.

Wherein, the diameter of the diffusion groove 2 is 0.5-2mm, and the depth is 0.4-0.6 times of the diameter.

Wherein, a plurality of diffusion grooves 2 are arranged on the upper surface and the lower surface of the diffusion film body 1.

The diffusion groove 2 simulates the structure of diffusion particles and is cylindrical or spherical, the diameter is 0.05-2.0mm, the depth is generally 0.4-0.6 times of the diameter, the diameter and the depth are randomly distributed on the surface of the whole diffusion film body 1 within a limit value range to form a diffusion structure, the diffusion structure is copied on materials (PMMA, PC and PS) to achieve a certain diffusion effect, the diffusion structure can be copied on one surface or two surfaces of the diffusion film body 1, the thickness of the diffusion film body 1 is 0.5-2.0mm, the size of the diffusion structure is adjusted according to the required diffusivity and haze of the diffusion film body 1, the higher the required haze is, and the smaller the design of the diffusion structure is.

Because ball, cylinder compare triangular prism, triangular pyramid have the biggest specific surface area, and structure size is random in certain extent, the biggest surface area energy such as shape hemisphere, short cylinder, ellipse hemisphere can be the biggest with light diffusion, and the diffusion barrier on the contrast market can effectual reduction diffusion particle's addition, effectively increases the light efficiency of diffusion barrier simultaneously.

Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
