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.
Temperature range:
A.storage temperature:25℃±10。
B.Long term use environment temperature:0~80℃
C.relative air humidity:45%~75%。

excellent for workstations required lighting application UGR<19,for example LED Panel light;
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.
