摘要： A multilayered reflective body which is thermoformable and capable of being fabricated into a number of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body is formed from at least two diverse polymeric materials which differ in refractive index and which are arranged in substantially parallel alternating layers. The polymeric body is reflective in appearance yet is transparent or, colored if a coloring agent is included, upon illumination from a back light source. The polymeric body has application in variety of areas such as in an automobile lighting lens which is reflective and thereby indiscernible yet transmissive upon exposure to a back light source. Additionally, various parts of consumer appliances, for example a refrigerator door, can be formed from the polymeric body.

摘要： Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.

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。

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.
