Anti-glare diffusion plate with low light loss and preparation method and application thereof

Abstract

The invention discloses an anti-glare diffusion plate with low light loss and a preparation method and application thereof. The diffusion plate is formed by mono-dispersing and filling organic silicon resin microsphere powder with volume percentage of 0.05-2% in optics grade polymethyl methacrylate matrices. The diffusion plate has the high scattering and low light loss characteristics, has lightsource illumination color rendering property being not likely to change, can be used in the high-power LED illumination fields, such as indoor and outdoor LED lamps, planar illumination, art illumination, soft illumination or LED-TV direct liquid-crystal backlight illumination, obtain the illumination effect of uniform brightness, eliminate uncomfortable glare and damage caused by directional hard light with high color temperature on the human eyes and improve the optical efficiency and illumination quality and has broad application prospect.

Description

technical field [0001] The invention relates to the lighting field, in particular to an anti-glare and low-light-loss diffusion plate, a preparation method and application thereof. Background technique [0002] In the field of lighting engineering, in order to obtain uniform and soft lighting effects, light diffusion (light scattering) materials and technologies have been widely used. These techniques can be broadly divided into two categories: area scattering and volume scattering. Surface scattering technology includes surface frosting, embossing, making microprisms, powder spraying, coating, etc.; volume scattering technology refers to the process of filling light diffusing agents in glass or plexiglass. Light diffusing agent refers to the transparent ceramic powder or organic resin powder that is immiscible with the matrix material, or the immiscible transparent plastic is made into a plastic alloy by the method of physical blending. scattering.

Problems solved by technology

[0005] The purpose of the present invention is to provide a high light diffusivity and light transmittance according to the glare discomfort or even permanent damage to human eyes caused by existing high-power white light LEDs and the contradiction between light transmittance and light diffusivity. It can also eliminate the glare discomfort and damage caused by high color temperature directional strong light to the human eye. Anti-glare and low light loss diffuser
