    Abstract: Various embodiments of lightguides and illumination systems that include lightguides are disclosed. In one or more embodiments, a lightguide can include first and second light extractors (330,340) that extract light that would otherwise be confined and propagate within the lightguide along the length of the lightguide primarily by total internal reflection. The first and second light extractors can form respective first and second patterns along a length of the lightguide. Light extracted by the first light extractors can exit the lightguide primarily along a first direction (306). Light extracted by the second light extractors can exit the lightguide primarily along a second direction (308) different from the first direction. A brightness of the total light extracted by the first light extractors can be larger than a brightness of the total light extracted by the second light extractors.

    Abstract: 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.

    Abstract translation: 光源包括具有包括光学膜的顶侧的光导，包括漫反射器的底侧和在顶侧和底侧之间延伸的输入侧。 照明源设置在光导的输入侧附近。 光学薄膜具有相邻的第一和第二区域，每个区域基本上延伸光学叠层的整个厚度或光学薄膜的至少一个光学分组的整个厚度。 光从光源中传播的光源进入光导，并且主要通过光学干涉被光学膜反射或透射。 对于至少一个第一入射角和至少一个波长，光学膜的第一和第二区具有基本相等的光透射率。 对于至少一个第二入射角和至少一个波长，第二区具有比光学膜的第一区大得多的光透射率。

    Abstract: Described are adhesive compositions containing a block copolymer component that includes a midblock segment and a plurality of end block segments, each end block segment comprising polystyrene, a (meth)acrylic functional additive having a glass transition temperature of from 50° C. to 160° C., a first tackifier compatible with the midblock segment and containing a hydrocarbon, and a second tackifier compatible with the end block segments and containing a polyphenylene ether. These compositions are useful in providing pressure-sensitive adhesives that are melt processible, display a high temperature resistance, and effectively bond to low surface energy substrates.
