Abstract:
Gradient optics for controllable light distribution for LED light sources. In an aspect, an apparatus is provided that includes a panel coupled to receive light emitted from a light source and gradient optics disposed on the panel. The gradient optics providing a transparency gradient that filters the light to achieve a selected emitted light intensity variation across a selected surface of the panel.
