Abstract

The utility model discloses a kind of hot-forming control light diffusing sheets, including using plate, the frosted layer in the front surface of plate and the optical layer in the rear surface of plate made of transparent plastic；Optical layer includes several micro-structures made of compacting.It is good to the diffusion of light that the utility model has, and can be very good to shrink beam angle, removal polarisation, removal veiling glare, the good feature of control optical property.

Description

Hot-forming control light diffusing sheet

Technical field

The utility model relates to light field of diffusion technologies, more particularly, to a kind of hot-forming control light that control optical property is good Diffuser plate.

Background technique

Light diffusing sheet is to encounter two refractive index (density) on the way using light diameter of being expert at by means chemically or physically When different medium, the physical phenomenon of refraction, reflection and scattering occurs, by adding in the Substrate basis such as PMMA, PC, PS, PP The refraction, reflection and scattering for adding inorganic or organic light diffusing agent artificially to adjust light, make light that different directions occur, to change The travelling route of darkening realizes that incident light sufficiently dissipates the effect that color generates optics diffusion with this.

Chemical particle is mainly added as scattering particles in traditional diffuser plate in diffuser plate substrate, is passing through light Refraction, reflection and scattering constantly occurs when scattering layer in the different medium of two refractive index, optics diffusion is generated with this Effect.

With the increasingly raising that people's focus ring border requires, various needs are also more and more, such as UGR, polarisation and optically focused Various demands.Common light diffusing sheet uses photodiffusion material extrusion molding, the only function of light diffusion, it is desirable to increase other If function, and need additionally to increase a component to increase assembly difficulty, and risk is big to achieve the goal, it is at high cost.

Summary of the invention

The purpose of the invention of the present invention is to overcome light diffusing sheet assembly difficulty in the prior art big, risk greatly and Deficiency at high cost provides a kind of hot-forming control light diffusing sheet that control optical property is good.

To achieve the goals above, the utility model uses following technical scheme:

A kind of hot-forming control light diffusing sheet, including using plate made of transparent plastic, set on the front surface of plate On frosted layer and the optical layer in the rear surface of plate；Optical layer includes several micro-structures made of compacting.

The incidence surface of the utility model is equipped with frosted layer, and frosted layer is fine grinding sand, and main function is to break up light, is reached The purpose of light diffusion；Optical layer is optical structure layers, after flat-plate molded, using hot-pressing technique on plate processing micro structure, lead to The light for crossing optical layer can reach corresponding optical demands, such as shrinks beam angle, depolarizes, remove veiling glare etc..

Preferably, the micro-structure is hexagon bulge loop, several row hexagon bulge loops are arranged successively, adjacent rows hexagon Bulge loop is connected with each other.

Each row hexagon bulge loop has the function of depolarizing, removes veiling glare.

Preferably, the micro-structure is round bulge loop, several concentric round bulge loops are outside successively by plate middle part Arrangement.

Each circle bulge loop has the function of shrinking beam angle.

Preferably, the micro-structure is rectangle bulge loop, several rectangle bulge loops are arranged in array.

Each rectangle bulge loop has the function of depolarizing, removes veiling glare.

Preferably, the rectangle bulge loop is divided into 4 triangle bulge loops by 4 separation lines.

Preferably, plate is in rectangle, plate is made of PC material, PS material or PP material；Plate with a thickness of 2mm To 10mm.

Therefore, it the utility model has the following beneficial effects: the diffusion to light is good, can be very good to shrink light beam Angle, removal polarisation, removal veiling glare, control optical property are good.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and detailed description.

Embodiment as shown in Figure 1 is a kind of hot-forming control light diffusing sheet, including is put down using made of transparent plastic Plate 1, the frosted layer 2 in the front surface of plate and the optical layer 3 in the rear surface of plate；Optical layer include compacting and At multiple micro-structures.

As shown in Fig. 2, micro-structure is hexagon bulge loop 4, multirow hexagon bulge loop is arranged successively, adjacent rows hexagon bulge loop It is connected with each other.

As shown in figure 3, micro-structure is round bulge loop 5, multiple concentric round bulge loops by being arranged successively outward in the middle part of plate.

As shown in figure 4, micro-structure is rectangle bulge loop 6, multiple rectangle bulge loops are arranged in array.

Rectangle bulge loop is divided into 4 triangle bulge loops 7 by 4 separation lines.

Plate is in rectangle, and plate is made of PC material, PS material or PP material；Plate with a thickness of 2mm to 10mm.

The incidence surface of the utility model is equipped with frosted layer, and frosted layer is fine grinding sand, and main function is to break up light, is reached The purpose of diffusion；Optical layer is optical structure layers, after flat-plate molded, using hot-pressing technique on plate processing micro structure, pass through Optical layer can reach corresponding optical demands, such as shrinks beam angle, depolarizes, remove veiling glare etc..

It should be understood that the present embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model.Furthermore It should be understood that after reading the content taught by the present invention, those skilled in the art can make the utility model various Change or modification, these equivalent forms also fall within the scope of the appended claims of the present application.
