What is the lampshade<\/h2>\t\t\t\t
\n\t\t\t\t\t

LED lampshade is a supporting component of LED lighting fixtures, mainly used to adjust the distribution of light. It reduces glare by scattering or concentrating light, making the lighting softer and more uniform, with a maximum transmittance of 94%. According to the material of the product, there are mainly PC lampshades, PVC lampshades, PP lampshades, acrylic lampshades, glass lampshades, plastic lampshades, paper lampshades, etc., which need to meet the characteristics of high light transmittance, strong diffusion, flame retardancy and impact resistance to adapt to the characteristics of LED light sources.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

\n PVC lampshade is a common lampshade material, which is currently the second most commonly produced plastic and the most widely used plastic. The prominent advantages of PVC lampshades are flame retardancy, wear resistance, chemical corrosion resistance, and low gas and water vapor leakage rates. In addition, PVC lampshades have excellent comprehensive mechanical properties, transparency, electrical insulation, thermal insulation, noise reduction and shock absorption. However, PVC lampshades have poor thermal stability and impact resistance, and are prone to brittleness when using rigid or flexible polyvinyl chloride. <\/div>\n <\/div>\n\n <\/div>\n <\/div>\n <\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
