Problems solved by technology

For light-scattering materials, light transmittance and light diffusivity (or haze) are a pair of contradictory technical indicators. Higher light transmittance is usually at the expense of light diffusivity. The glare problem is serious when the diffuser is used in the luminaire, especially when used in a closed space in a public environment such as offices, libraries, hospitals, schools, etc., it will feel uncomfortable to the eyes

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as Figure 1-Figure 3 As shown, a diffuser plate with anti-glare function for converting surface light from a point light source includes a diffuser base 1, one side of the diffuser base 1 is a frosted surface 2, and the other side of the diffuser base 1 is provided with orange pattern light diffusion points 3. The orange pattern light diffusion point 3 includes a plurality of microstructured light diffusion base points 4, which are arranged consecutively with each other. Made of anti-glare diffuser polymethyl methacrylate material.

[0021] The principle of the anti-glare diffusion plate given in this practical information is to use the different refractive index of nano-scale micro-pearl diffuser and optical acrylic and other substrates. When light passes through these media with different refractive indices, many penetrating refractions will occur, and The ...

Abstract

The invention discloses an anti-dazzle diffuser plate for converting a point light source into a surface light source. The anti-dazzle diffuser plate for converting a point light source into a surface light source includes a diffuser plate matrix, wherein one side of the diffuser plate matrix is a frosted surface, and the other side of the diffuser plate matrix is provided with orange-peel light diffusion points which include a plurality of microstructure light diffusion basic points which are arranged continuously; and the upper part of each microstructure light diffusion basic point is a hexagon, and the lower part of each microstructure light diffusion basic point is a cone bottom. The anti-dazzle diffuser plate has high permeability, and can also convert a point light source into a surface light source so as to achieve the anti-dazzle effect, and has the advantages of being simple in structure, being convenient to use and being high in practicality.

Description

technical field [0001] The invention relates to a diffusion plate for converting surface light from a point light source with anti-glare function. Background technique [0002] In liquid crystal display devices such as glass curtain walls, televisions, mobile phones, computers, car GPS navigators and other imaging display devices, due to the difference in light and darkness, there are often problems such as unclear display effect and light stimulation to human eyes. [0003] In order to obtain a uniform and soft display effect, the light diffusion plate has been widely used. The light diffusion plate is to add light scattering materials to the substrate by chemical or physical means, and to use the medium of different refractive index (density) encountered by the light during transmission. When refraction, reflection and scattering occur, the incident light is fully scattered to produce the effect of optical diffusion. For light-scattering materials, light transmittance and...
