摘要： An illumination system includes a lightguide having light extractors. A first light source is disposed at an end face of the lightguide. Light emitted by the first light source is extracted from the lightguide by the light extractors and exits the lightguide primarily along a first direction different than the length direction. A second light source is disposed along the length of the lightguide. Light emitted by the second light source enters the lightguide from a first side surface and exits the lightguide from a different second side surface along a second direction different than the first and length directions. Light emitted by the second light source has a first divergence in a first plane before entering the lightguide through the first side surface and a different second divergence in the first plane after exiting the lightguide from the second side surface.

摘要： A light source includes a lightguide having a top side comprising an optical film, a bottom side comprising a diffuse reflector, and an input side extending between the top and bottom sides. An illumination source is disposed proximate the input side of the lightguide. The optical film has adjacent first and second zones, each zone extending substantially an entire thickness of the optical stack or an entire thickness of at least one optical packet of the optical film. Light enters the lightguide from the light source propagating within the lightguide and being either reflected or transmitted by the optical film primarily by optical interference. For at least one first incidence angle and at least one wavelength, the first and second zones of the optical film have substantially equal optical transmittance. For at least one second incidence angle and at least one wavelength, the second zone has substantially greater optical transmittance than the first zone of the optical film.

A first portion of light propagating within the lightguide and extracted exits the lightguide through a first area of the lightguide having an optical reflectance of at least 30% and an optical transmittance of at least 5% for normally incident light at a wavelength of the extracted light. A second portion of light propagating within the light guide and extracted exits the lightguide through a different second area of the lightguide having an optical transmittance of at least 80% for normally incident light at the wavelength of the extracted light.

In some cases, the structured layer is removably laminated onto a substrate to provide uniform light extraction. In some cases, indicia are cut out of the structured layer and laminated onto the substrate. In some cases, the structured surface of the structured layer is selectively filled to form a pattern for light extraction. In some cases, a tool for producing a structured layer has a region of structures selectively filled to form a pattern for light extraction on the produced structured layer.
