摘要： In one aspect, a light emitting device comprises a film-based lightguide including folded and stacked strips extending from a lightguide region of the film. In one aspect, the film comprises light extracting features defining light emitting regions that extract light from at least one light source positioned to emit light into the stacked end of strips. In one aspect, a flux of light emitted in a first direction by the light extracting features is greater than 70% of a total flux emitted from the light emitting regions, the light emitting regions have an average luminous transmittance greater than 70%, and the outermost surface of the device has an ASTM D523-89 60 degree gloss less than 50 gloss units. In one aspect, the device is a light fixture and the color of the object, such as a wall or ceiling, behind the film is unchanged when looking through the film.

摘要： A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.
