摘要: Illumination devices having a partially transmissive front reflector, a back reflector, and a cavity between them are disclosed. At least one light injector including a baffle and a light source is disposed in the cavity. The light injector is capable of injecting partially collimated light into the cavity. The output area of the illumination device can be increased by disposing light injectors progressively within the cavity, without sacrificing uniformity of the light emitted through the output area.

摘要: A film construction (610) includes a group of microlayers that reflect normally incident light polarized along a first axis more than normally incident light polarized along a second axis. The microlayers are arranged into optical repeat units (ORUs) that have a layer thickness distribution along a thickness axis perpendicular to the first and second axes that provides the group of microlayers with an intermediate reflectivity over an extended reflection band for a given incidence condition. The ORUs include thinner ORUs whose thicknesses are less than an average thickness, and thicker ORUs whose thicknesses are greater than the average thickness. The group of microlayers is optically immersed in a medium having a refractive index greater than air, such that “supercritical light” can propagate through the microlayers. The microlayers are oriented such that, on average, the thinner ORUs are closer than the thicker ORUs to an output surface of the construction. By “supercritical light” is meant that travels through the film at an angle that is more oblique than can be achieved by illumination from air using a flat, smooth air/film interface.
摘要翻译: 膜结构(610)包括一组微层,其反射正常入射的光沿着第一轴偏振,而不是沿着第二轴偏振的正常入射光。 微层布置成光学重复单元(ORU),其具有沿着垂直于第一和第二轴线的厚度轴线的层厚度分布,其为给定的入射条件在延伸的反射带上提供中间反射率的微层。 ORU包括厚度小于平均厚度的更薄的ORU,以及厚度大于平均厚度的较厚ORU。 微组织光学地浸入折射率大于空气的介质中,使得“超临界光”可以传播通过微层。 微层的取向使得平均来说,更薄的ORU比较厚的ORU更接近于结构的输出表面。 “超临界光”是指以比通过使用平坦,平滑的空气/膜界面的空气照明可以实现的倾斜更倾斜的角度穿过膜。

摘要: Optical stack is disclosed. The optical stack includes a first optical stack that includes, a first optical adhesive layer, and a reflective polarizer layer that is disposed on the first optical adhesive layer. The reflective polarizer layer substantially reflects light of a first polarization state and substantially transmits light of a second polarization state orthogonal to the first polarization state. The optical stack also includes a second optical stack that includes a second optical adhesive layer, a low index layer that is disposed on the second optical adhesive layer and includes a plurality of voids dispersed in a binder, and a light directing film that is disposed on the low index layer and includes a plurality of unitary discrete structures. Portions of each unitary discrete structure penetrate into the first optical adhesive layer. Portions of each unitary discrete structure do not penetrate into the first optical adhesive layer. Each unitary discrete structure defines a penetration depth and a penetration base at the interface between the penetrating and non-penetrating portions of the unitary discrete structure. The penetration base has a minimum penetration base dimension. The plurality of unitary discrete structures has an average penetration depth and an average minimum penetration base dimension. The ratio of the average penetration depth to the average minimum penetration base dimension is at least 1.5. The peel strength between the first and second optical stacks is greater than about 30 grams/inch.
