Abstract
Gradient optics for even light distribution of LED light sources. In an aspect, an apparatus is provided for uniform distribution of light emitted from a light source. The apparatus includes a panel coupled to receive the light emitted from the light source, and gradient optics disposed on the panel, the gradient optics providing a matching transparency gradient that is aligned with the light source to evenly distribute the emitted light. In another aspect, an apparatus includes means for receiving the light emitted from the light source, and means for providing a matching transparency gradient that is aligned with the light source to evenly distribute the emitted light.
