    • 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.
    • 背光单元(10)具有中空腔(16)而不是使用光导。 布置一个或多个光源(24a-c),诸如LED,以将光发射到由前部(12)和后部反射器(14)形成的空腔中。 背光通常是边缘照明型。 背光源可以具有较大的面积,较薄并且由比传统设备更少的组件组成。 其设计允许光回收。 该单元发射预定极化的光,并且可以被布置成具有期望的水平/垂直视角特性。 光均匀分布在引导件内,并且光输出(20b,20d)基本准直。 这样的背光灯占据由两个参数定义的参数空间中的特定区域:首先,输出排放面积与总排放源面积的比值应在0.0001到0.1的范围内; 第二,SEP与空腔高度的比值(H)应在3到10的范围内,其中SEP是平均平面视图源分离,平面中光源的平均间距的特殊测量 的单位。 还有关于所需数量的光源N的讨论,它们在空腔的周边附近的布置以及输出发射区域的形状和尺寸。 还公开了当Madjacent源的子集(其中M为至少0.1N或M> 2或两者)时要维持的所需的最小亮度均匀性(VESA)值。 背光可用于显示器或用于一般照明目的。

    • 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.
    • 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。 微层被布置成光学重复单元(ORU),光学重复单元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了一组微层的中间反射率。 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”可以通过微层传播。 微层的取向使得平均来说,更薄的ORU比较厚的ORU更接近结构的输出表面。 “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。
