1. Prism Cone UGR diffuser with Concave hexagon,cone bottom,takes on homogeneous look due to unidirectional structure;

2. Scientific designed structure,well defined lamp direction with average beam angle 85 degree,assist to improve the light 
efficiency and reasonable glare suppression;

3. Homogeneous glare reduction in all C-levels,excellent  for workstations required lighting application UGR<19,for example LED 
Panel light;

4. On equal conditions, the light transmittance is obvious higher than traditional matte or orange peel texture diffusion sheet, 
at the same time effectively suppress the glare value.

Attention:

In conjunction with diffusion film and light guide plate,Prism Cone diffuser positioned in outer layer with the texture facing away from the led or lamp;diffusion film located in the middle layer with the microstructure facing away from the led or lamp also; the light guide plate placed on the bottom layer with the texture side placed contrary to prisma cone and diffusion film.
