GT-QTA Acrylic prism diffuser sheet is designed with scientific structure neatly arranged protrude quantum hexagon. When the LED light through the surface of prism,the average light angle will be changed to 85 degree, it doesn’t only decreasing the glaring value of light to get the reasonable glare suppression,but also improving the lighting efficiency.Without change led light source and other electrical specification,the light transmittance of pyramid light diffuser sheet is obvious higher than traditional matte or orange peel texture light diffusion sheet, also effectively suppress the glare at the same time.The UGR is less than 19,which is the best choice for the education lighting and the office lighting.
