Abstract
An illumination source and a method therefor. A light source includes a light circuit configured to process light and direct light, and a lighting element optically coupled to the light circuit to provide multiple colors of light. The light circuit propagates light using light guides. The use of light guides eliminates the use of free space optical elements, enabling the creation of more compact light sources. Furthermore, the use of light guides may enable the creation of light sources with fewer mechanical restrictions, thereby making the light sources potentially more reliable and less expensive.
