A. Excellent Light Diffused Effect And 95% Of Light Efficiency
For resolving the glare problem of LED, people usually use the traditional diffuser films, diffuser boards…...the existed diffusing material. Although those products can spread the light evenly, they only keep the light efficiency 50% -60%. However, if the light efficiency is over 60%, it can’t spread the light evenly and improve the glare problem. Comparing the functions of different diffusing materials in the same test condition, we can see the LED light point very clearly without using FD Film. Contrarily, when we use the Focal Diffuser filmTM, that can diffuse the light uniformly and eliminate the glare problem. After placing FD filmTM will easily reduce LED glare, no matter what power LED you use.

Remark
|
The luminance is reduced substantially.

The light point can’t be eliminated.
|
The light point is diffused evenly.

B. Eliminate Multiple Shadows Of LED
Multiple shadows will interfere with man’s eye sight, and cause uncomfortable feeling while reading for a long time. After using Focal Diffuser film, it reduces the multiple shadows into only one shadow.
C. The Ultra Wide Angle Of Light Spreading ±85° (170°)
D.Do Not Change LED Color Temperature
Do not influence CIE color and color temperature of LED itself, and retrieve LED the high color performance.
E. Optical Level Of Single Material Polycarbonate, Reusable And High-temperature Resistance
The Focal Diffuser film is made of pure Polycarbonate and can be reused. It has no any additive or content that will damage the environment. (such as nanoparticles and any diffuser material)
