Abstract

Embodiments described herein provide optical systems that can mix colors to produce illumination patterns having a large area with uniform color. One embodiment of an optical system can include a set of optical units that each produces an illumination pattern with uniform color and intensity. The optical units are spaced so that the individual illumination patterns overlap to create an overall illumination pattern with an overlap area. In the overlap area, the colors emitted by the individual optical units mix to create a desired color. Embodiments of optical systems can provide beam control so that the optical units emit a high percentage of light in beam.
