Abstract:
A light-diffusing element with high coupling efficiency to LED sources. The light-diffusing element may be a glass monolith that includes a plurality of internal voids. When light propagating through the monolith encounters the internal voids, it is scattered in a transverse direction and exits the lateral surface of the monolith to provide a broad-area illumination effect. The glass monolith has a cross-section with a dimension between 1 mm and 20 mm and features a numerical aperture of at least 0.7 to facilitate efficient coupling to LED sources. The internal voids have a cross-sectional dimension that ranges from about 100 nm to 20 microns and a length that ranges from about Ιμιη to a few millimeters. The internal voids occupy between 0.5% and 20% of the cross-section. The light-diffusing element can be configured as a rod or as a bent or arbitrarily-shaped fixture.

Abstract:
Methods and apparatus f or electrically controlIing a Iuminaire to alter it s appearance and illumination effects are disclosed. A luminaire (100) having a multiplexing controller controlling one or more LED light sources (110) and one or more electrically switchable optical elements (150). The light sources are switched between at least two illumination states and the optical elements are switched between at least two optical states during an illumination period. The switching sequence is fast enough not to be detected by an observer. As a result the lighting module or luminaire is perceived to have a substantially continuous light output. The multiplexing controller rapidly time sequences the states of light sources and switchable surfaces to produce visual changes to the luminaire and/or objects illuminated by the luminaire.
