Abstract

In this paper, we propose and demonstrate a novel design to make color mixing and projection of RGB LEDs. The optical elements include a high reflective light pipe, a volume scattering diffuser and a TIR lens. The system optical efficiency is around 46 % while the color is well mixing for the cases at the CCTs of 6500K, 4500K and 3000K.
