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.

摘要翻译： 将不连续的光漫射基板放置在LED光源内。 在一个实施例中，衬底被放置在LED光源和光导之间。 光扩散基板可以包括多个气泡，凹槽或两者，有效地混合着色光并产生离开光导的白光。 还公开了具有含气泡的衬底的光学器件和光源的构造方法。
