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： A hollow light-recycling backlight has a “semi-specular” component providing a balance of specularly and diffusely reflected light improving the uniformity of the light output. The component may be arranged on the reflectors (1021), (1014) or inside the cavity (1016). This balance is achieved by designing the component's “transport ratio” defined by (F−B)/(F+B), (F and B are the amounts of incident light scattered forwards and backwards respectively by the component in the plane of the cavity) to lie in a certain range. Furthermore, the product of the front and back reflector “hemispherical” reflectivities should also lie in a given range. Alternatively, the “cavity transport value”, a measure of how well the cavity can spread injected light from the injection point to distant points in the cavity should lie in a further range and the “hemispherical” reflectivity of the back reflector should be >0.7.

摘要： A backlight unit (10) has a hollow cavity (16) instead of employing a light guide. One or more light sources (24a-c), such as LEDs, are arranged to emit light into the cavity, which is formed by a front (12) and a back reflector (14). The backlight is typically of the edge-lit type. The backlight can have a large area, is thin and consists of fewer components than conventional devices. Its design permits light recycling. The unit emits light of a predefined polarisation and can be arranged to have desired horizontal/vertical viewing angle properties. Light is uniformly distributed within the guide and the light output (20b, 2Od) is substantially collimated. Such backlights occupy a specific region in a parameter space defined by two parameters: first, the ratio of the output emission area to the total source emission area should lie in the range 0.0001 to 0.1; and second, the ratio of the SEP to the height of the cavity (H) should be in the range 3 to 10, where the SEP is an average plan view source separation, a special measure of the average spacing of light sources in the plane of the unit. There is also a discussion on the required number of light sources N, their arrangement near the periphery of the cavity, as well as the shape and size of the output emission area. A required minimum brightness uniformity (VESA) value to be maintained, when a subset of Madjacent sources is switched off (where M is at least 0.1 N or M>2 or both), is also disclosed. The backlight can be used for a display or for general lighting purposes.

摘要： Multilayer optical films are disclosed that exhibit high reflectivity at normal incidence for all polarizations but preferentially transmit high angle rays in one or two orthogonal planes of incidence. Both symmetrical and asymmetrical constructions are disclosed. The films can be used in direct-lit backlights and in lighting systems other than direct-lit backlights, such as edge-lit backlights, and non-backlight lighting systems such as systems intended for general illumination without the need for any graphic component, such as luminaires and task lights.
