Problems solved by technology

The multi-layer stacked polymer composite light diffusion plate disclosed by the present invention adopts a multi-layer light diffusion plate with more than three layers of different functions similar to a "sandwich", so as to ensure uniform light diffusion, and then achieve high light efficiency, high haze, and uniformity High optical effects such as high color rendering, so as to solve the problems of poor light efficiency, haze and light transmittance in the prior art, but this patent has the phenomenon that it is not convenient to remove the surface cleaner foam, and needs to be improved
[0006] However, the existing composite light diffusion plate cleaning equipment still has some shortcomings during use, such as: it is not convenient for continuous surface cleaning, it is not convenient for mechanized processing and production, and it is not convenient for surface cleaner foam The phenomenon of removal can not achieve the phenomenon of overall smooth operation, so a composite light diffusion plate and production method with convertible LED spectrum are needed to solve the above-mentioned problems

Description

technical field [0001] The invention relates to the technical field of composite light diffusion plate equipment, in particular to a composite light diffusion plate with convertible LED spectrum and a production method. Background technique [0002] The light diffusion plate is a physical phenomenon of refraction, reflection and scattering that occurs when the light encounters two media with different refractive indices (density) on the way, through chemical or physical means, through PMMA, PC, PS, PP Adding inorganic or organic light diffusing agents to substrates such as hips, or artificially adjusting the light through the array arrangement of micro-features on the surface of the substrate, causing the light to refract, reflect, and scatter in different directions, thereby changing the path of light , to achieve sufficient dispersion of incident light to produce the effect of optical diffusion. There are three types of light diffusion plates, which are generally widely us...
