Light diffusion plate and preparation method thereof

Abstract

The embodiment of the invention provides a light diffusion plate and a preparation method thereof, and relates to the field of illumination material technology. The light diffusion plate comprises transparent base materials and light scattering particles, the light scattering particles are dispersed in the transparent base materials, and surfaces of the light scattering particles are connected with molecular chains, wherein the molecular chains connected with the light scattering particles are the same as molecular chains of the transparent base materials. When the light scattering particles and the transparent base materials are blended, the molecular chains at the surfaces of the light scattering particles can be fully extended and blended into the transparent base materials to increasethe mutual effect of the interfaces. Because the ratio of the density and the length of the molecular chains at the surfaces of the light scattering particles is lower than the ratio of the density and the length of the molecular chains in the transparent base materials, the intensity of the mutual effect of the interfaces is lower than the intensity of the base materials. When an external force pressed on the materials reaches a certain value, the interface active force can be unsticked in advance, so that a lot of energy is absorbed, and the impact intensity of the light diffusion plate is improved.

Description

Technical field

[0001] The invention belongs to the technical field of lighting material preparation, and in particular relates to a light diffusion plate and a preparation method. Background technique

[0002] Light Emitting Diode (LED) lighting is the third leap in human lighting history after incandescent lamps and fluorescent lamps. LED is a solid semiconductor light source, which has long been used in the display field. At present, it is gradually entering the field of lighting as a new type of solid light source. Compared with traditional lighting, LED lighting is energy-saving, environmentally friendly and safe. Therefore, LED lighting will replace the current incandescent lamps and fluorescent lamps on a large scale.

[0003] However, LED lighting is more dazzling than traditional lighting, and a light diffuser is needed to soften the light before it can be used for indoor lighting. The light diffuser can convert a point light source into a surface light source. The pr...
