Good diffusion performance: After the PC diffusion plate is illuminated, the light is uniform and the light is soft. High light transmission performance: reduce energy consumption, improve the illumination of the lamp. Good flatness: the milky board has good flatness, less translucent crystal points and high finish. Small impact on the light source: Keeps the color temperature of the light source consistent and reduces color offset. Minimize light interference: maintain the design of the original light distribution curve of the lamp. Good weather resistance: -40℃~120℃ climate conditions, its performance is not affected.
