As to the different production processes and technology, the products in the light diffuser market is quite different. some can solve the fog of the diffusible materials well，but some can not solve the transmittance of the materials fantastic.
Then how to choose the best suitable light diffusion agent for different materials?
It needs to confirm the different materials you will use for and your detailed requirements of the product and the current basic knowledge of a variety of light diffusion agent.
There is inorganic and organic light diffusion agent in the category. while if we distinguish it by materials, there are many types of light diffusion agent such as silicone, styrene, polymethacrylic, silicone dioxide, calcium carbonate, and so on.
In terms of the particle size of the light diffusion agent, it is 1-3μm, 2-5μm, 2-8μm, 5-15μm and so on. different kinds of silicone resin powder have different astigmatism effects and transmittance.
Inorganic light diffusion agent are the main of nano barium sulfate, calcium carbonate, silicone dioxide, and so on. now, if you want to more than 50% transmittance for lampshade, then pls don’t choose it.
Organic light diffusion agent is included silicone, acrylic, styrene, and acrylic resins, these resins are transparent or semi-transparent and light can pass through most of them, because of the difference between the refractive index of the material and its substrate，the light passing through the substrate becomes bright and soft after several times of refraction, and it has little influence on the transmittance of the material. it’s a good choice for making light tube, lampshades, and other optical materials.
From the above analysis, we can get that organic light diffusion agent are the 1st choice of PC, acrylic, and other substrate materials for the led lampshade. Because of the different types of organic light diffusion agent, the materials themselves have a different refractive index of light, so there will be PC lampshade light diffusion agent, PMMA lampshade light diffusion agent, and other different categories.
