Abstract: Disclosed herein is an optical device having a light source and a viscoelastic lightguide. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The viscoelastic lightguide may comprise a pressure sensitive adhesive. The optical device may be used in a variety of constructions wherein the device emits light being transported within the viscoelastic lightguide. Constructions include those used for signs, markings, illumination devices, display devices, keypad assemblies and tail light assemblies for vehicles.

Abstract: An optical article, such as a backlight for electronic display devices, is disclosed. The optical article includes a lightguide, a viscoelastic layer disposed on the light guide and a nanovoided polymeric layer disposed on the viscoelastic layer. The nanovoided polymeric layer comprises a plurality of interconnected nanovoids and at least some of the interconnected nanovoids are connected to one another by hollow passages. The lightguide may be optically coupled to a light source, and the viscoelastic layer and the nanovoided polymeric layer may be used in conjunction with the lightguide to manage light emitted by the light source.

Abstract: The present disclosure describes advanced lighting elements, in particular solid-state lighting elements, and luminaires that include an array of lighting elements. The lighting elements, and luminaires including the lighting elements can exhibit benefits that include high optical efficiency and therefore high luminous efficacy; extraordinary directional control and therefore extraordinary glare control and efficacy of delivered lumens; and exceptional mixing of individual-device emission providing exceptional suppression of punch-through and color breakup. In many cases, the architecture can be amenable to low-cost manufacturing in a modular format.
