Lixin uses modified technology to develop special panels for LED lighting advertising signs, which have high light transmittance, bright colors, good light diffusion and light source concealment. The new is guaranteed under the condition that the original performance index of the polycarbonate sheet remains unchanged, the effect of scattering, refraction, and even color change occurs when light passes through the sheet, which not only enhances the brightness of the luminous body, but also enables the light emitted by the point light source to be evenly distributed. It has been widely used in the lighting projects of cities and scenic areas.
