Abstract: A variable index light extraction layer (100) suitable for use in optical applications is described. The variable index light extraction layer has first and second regions (140; 130) with different refractive indices, the regions being disposed such that for light being transported at a supercritical angle in an adjacent layer (120), the extraction layer can selectively extract the light in a predetermined way based on the geometric arrangement of the first and second regions. Also described are optical films and devices including the variable index light extraction layer, methods of making the extraction layer and methods of illuminating using the extraction layer.

Abstract: A sound absorbing luminaire providing lighting for an interior space environment and managing the acoustics within the environment. The luminaire includes a frame holding an acoustic film and a lighting element, forming a resonant cavity between them. The acoustic film is used for absorbing sound within the resonant cavity, and the lighting element provides light from a light source, such as LEDs, through the acoustic film. An optical film can be mounted in the frame between the acoustic film and the lighting element for providing a desired distribution of light.

Abstract: A backlight includes nl, n2, and n3 colored LED light sources of a first, second, and third (non-white) color respectively, and a drive circuit connected to these sources. The drive circuit is configured to drive each of the first, second, and third light sources within a specified percentage, such as 10%, of their respective maximum drive characteristics, and the numbers nl, n2, and n3 are selected so that light from the energized first, second, and third LED light sources, when combined, is substantially white. In some cases, the backlight also includes a number n4 of white LED sources, and the colored LED sources may or may not be driven within 10% of their maximum ratings. The number n4 of white sources is selected to increase the brightness of the backlight while maintaining the color gamut of the backlight output within a specified percentage, such as 10%, of a desired specification.
