Integral Illumination

Integral Illumination is a "true" programmable lighting technology that enables a single panel-shaped device to replicate the illumination effects of a wide range of light sources—e.g., chandelier, spotlight, natural light, etc. The technology is a variant of integral imaging, an existing technology commonly used to build glasses-free 3D TVs, albeit with a custom optical design necessitated by its application to lighting. Furnishing a room with Integral Illumination will allow occupants to freely alter its ambience to suit their changing needs, to degrees much larger than those offered by color-changing LEDs; we expect the technology to be useful for outdoor public lighting (e.g., street lamps) as well. As of now the technology is still in a basic research phase, and several issues need to be resolved before real-world use.

Integral Illumination can be interpreted as a novel idea for using electronic displays as architectural components. While electronic displays have already found wide use in buildings for purposes such as exterior decoration, advertisement, etc., I believe that numerous other uses still remain unexplored that go beyond such common applications.
