Abstract: A backlight includes n1, 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 n1, 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.

Abstract: Disclosed herein is an optical device having a light source, a viscoelastic lightguide and a retroreflective film suitable for retroreflecting light. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The optical device may have a “front lit” configuration such that light being transported within the lightguide is extracted and retroreflected by the film toward a viewer. The optical device may have a “back lit” configuration such that light being transported within the lightguide is extracted and transmitted through the film toward a viewer. The retroreflective film may comprise beaded retroreflective sheeting such as that used in traffic signs and markings.

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: This application describes a front. lit reflective display assembly including a reflective display and an illumination article (600) for front - lighting the display when the article is optically coupled to a light source (601). The illumination article includes a variable index light extraction layer (630) optically coupled to a lightguide (610). The variable index light extraction layer has first and second regions, the first region comprising nanovoided polymeric material, the second region comprising the nanovoided polymeric material and an additional material, the first and second regions being disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light ectraction layer selectively extracts the light in a predetermined way based on the geometic arrangement of the first and second regions. Front- lit reflective display device including the front- lit reflective display assembly optically coupled to a light source are also described.
