Thin Hollow Light Guide for High Efficiency Planar Illuminator
Light guides have been widely used for transforming light sources into planar illuminator for Lighting applications. A hollow light guide with edge lit LED has been proposed to resolve the issues of weight, uniformity and efficiency. The experiment shows an overall efficiency of 82.4%, with an uniformity of 83.7%.

Development of Thin Film to Enhance OLED Light Luminous
An optical thin film was utilized to enhance light extraction efficiency of OLED up to 80%. Two kinds of micro metal oxidized particles were chosen to be doped into the optical thin film to increase scattering and refraction effect. The roughness surface was be fabricated on the top of thin film to change light output angle.

LED Package Lens Design for Short Distance Color Mixing
Color-dimmable W-LEDs are required to provide appropriate color mixing to achieve high color uniformity and not excessively increased the equivalent emitting area, otherwise it will affect the difficulty of the subsequent application. This study proposed a Serrated Light Mixing Chamber design to improve mixing performance for short distance color mixing.
