Abstract

Optical films with microstructures can achieve uniform illuminance on the target and glare control with no registration to LEDs. An engineered optical film design with microstructures on both sides is demonstrated. A spacing ratio of 1.64 is obtained compared to 1.28 with just LEDs while there is less light at higher angles for better glare ratings.
