Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a formula of a novel LED lampshade. Background technique [0002] The light source of the LED lamp is relatively concentrated, so it needs to pass through the lampshade to spread the light evenly. The currently researched PET light diffusion material is able to cause optical phenomena such as refraction, reflection, and scattering to occur during the passage of light, and can convert point light sources or line light sources into line light sources or surface light sources to achieve a uniform light effect. At present, most of the diffusion films use transparent PET as the substrate, and a light diffusion layer containing light diffusion particles is coated on the surface. Due to the use of a large amount of organic solvents in the process of processing this kind of diffusion film, it is very easy to cause environmental pollution. Moreover, the elastic modulus of the light-diffusing la...

AI Technical Summary

Problems solved by technology

Due to the use of a large amount of organic solvents during the processing of this diffusion film, it is easy to cause environmental pollution.

Moreover, the elastic modulus of the light-diffusing layer and the substrate is different due to their different materials. Once bent, it is easy to cause the light-diffusing layer to fall off or be damaged.

This increases the difficulty of the use of light diffusion film and reduces the yield of products.
