摘要：
A discontinuity-containing, light-diffusing substrate is placed within an LED light source. In one embodiment, the substrate is placed between an LED light source and a light guide. The light diffusing substrate may include a plurality of air bubbles, grooves or both, effective to mix the colored light and yield a white light exiting the light guide. Methods of constructing optical devices and light sources having a bubble-containing substrate are also disclosed.
