DESCRIPTION

Excellent selection of 100% virgin material

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

Scientific designed structure

Acrylic sheet with pyramid structure (The cells are pyramid in shape)—the geometry of pyramid structure is an array of convex cells rised from acrylic sheet, takes on homogeneous look due to unidirectional structure.

Increase visual comfortable

The unique designed structure that have the geometry of a pyramid to allow the light even diffusion, provide a unique in appearance and can be used in lighting fixture installations of increase visual comfortable;

Homogeneous glare reduction

Ther scientific designed structure, well defined lamp direction with average beam angle 85 degree, assist to improve the light efficiency and reasonable glare suppression; Homogeneous glare reduction in all C-levels, excellent for workstations required lighting application UGR<19, for example LED Panel light;

Application

The application is different depend on the edge -lit usage or back-lit usage, for example if it's side-lit usage, there will be four layer structure, from the top to bottom will be UGR diffuser sheet, the diffuser film and LGP and reflective film, it can be illustrated that the UGR diffuser positioned in outer layer with the texture face towards the observer; The diffusion film located in the middle layer with the micro structure facing towards the LGP; the LGP be placed between the diffusion film and the reflective film, and with the dot side facing towards the diffusion film, the smooth side towards the reflective film.

If it's back-lit usage, there will be two layer, from the top to bottom will first be UGR diffuser sheet, then the normal diffuser sheet, and the structure will be the UGR diffuser positioned in outer layer with the texture face towards the observer; the diffuser sheet located in the bottom layer which more closer to the LED source.
