Abstract: A nanostructured article includes a substrate; a plurality of first nanostructures disposed on, and extending away from, the substrate; and a covalently crosslinked fluorinated polymeric layer disposed on the plurality of first nanostructures. The plurality of first nanostructures includes polyurethane. The polymeric layer at least partially fills spaces between the first nanostructures to an average minimum height above the substrate of at least 30 nm such that the polymeric layer has a nanostructured surface defined by, and facing away from, the plurality of first nanostructures.

Abstract: A microstructured article includes a nanovoided layer having opposing first and second major surfaces, the first major surface being microstructured to form prisms, lenses, or other features. The nanovoided layer includes a polymeric binder and a plurality of interconnected voids, and optionally a plurality of nanoparticles. A second layer, which may include a viscoelastic layer or a polymeric resin layer, is disposed on the first or second major surface. A related method includes disposing a coating solution onto a substrate. The coating solution includes a polymerizable material, a solvent, and optional nanoparticles. The method includes polymerizing the polymerizable material while the coating solution is in contact with a microreplication tool to form a microstructured layer. The method also includes removing solvent from the microstructured layer to form a nanovoided microstructured article.

Abstract: Extended area lighting devices include a light guide and diffractive surface features on a major surface of the light guide, at least some diffractive surface features adapted to couple guided-mode light out of the light guide. The diffractive features include first and second diffractive features disposed on respective first and second portions of the major surface. A patterned light transmissive layer, including a second light transmissive medium, optically contacts the second diffractive features but not the first diffractive features. A first light transmissive medium optically contacts the first but not the second diffractive features. The first and second portions may define indicia, and the first and second diffractive features provide low distortion for viewing objects through the light guide such that the indicia is not readily apparent to users when guided-mode light does not propagate within the light guide. Optical films having such diffractive features are also disclosed.

Abstract: Disclosed herein are LED devices having lenses and methods of making the devices. The LED devices are made using an optical layer comprising a plurality of lens features. The optical layer is disposed relative to the LED die such that at least one LED die is optically coupled to at least one lens feature. A lens can then be made from the lens feature and excess optical layer removed to provide the device.
