摘要： Methods and systems for providing a light device that can emit light and sense light are disclosed. In one embodiment, a lighting device includes a light guide having a planar first surface, the light guide configured such that at least some ambient light enters the light guide through the first surface and propagates therein, and at least one light detector disposed along an edge of the light guide, the at least one detector optically coupled to the light guide to receive light propagating therein. The light detector can be configured to produce a control signal. In some embodiments, the lighting device also includes at least one light turning feature disposed on the first surface, the at least one light turning feature configured to direct light incident into the light guide through the first surface.

摘要： Illumination systems and methods of manufacturing the same. In one embodiment, an illumination system includes a plurality of light sources configured to emit light into a light panel and a plurality of light turning features disposed on the light panel configured to turn light out of the light panel. The light sources can be configured to emit different colors of light than one another and the light turning features can be arranged such that a first light turning feature turns more light having a first color than any other color of light and such that a second light turning feature turns more light having a second color than any other color of light. In another embodiment, a method of manufacturing an illumination system includes providing a light panel and positioning a luminance altering element on the light panel such that a luminance characteristic of the panel changes.

摘要： The color reflected by an interferometric modulator may vary as a function of the angle of view. A range of colors are thus viewable by rotating the interferometric modulator relative to an observer. By placing a textured layer between an observer and an interferometric modulator, a pattern which includes the range of colors may be viewed by the observer, and the range of colors may thus be viewable from a single viewing angle.
