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 backlight includes a lower light guide having a specularly reflecting bottom surface and an opposing specularly reflecting perforated mirror film having a plurality of light transmission apertures. The specularly reflecting perforated mirror film has a polymeric multilayer structure, where non-perforated areas of the specularly reflecting perforated mirror film have a light reflectance value of 98% or greater and the specularly reflecting bottom surface has a light reflectance value of 98% or greater. A light collimating injector directs input light into the lower light guide. The light propagating generally parallel to the specularly reflecting perforated mirror film along a horizontal plane. The light collimating injector provides input rays into a vertical plane, the vertical plane being orthogonal to the horizontal plane, and forming an angle having an absolute value of 30 degrees or less with an intersection of the vertical and horizontal planes. An upper light cavity is disposed on the lower light guide. The upper light cavity has a light emission surface and a light input surface. The light input surface is at least partially defined by the specularly reflecting perforated mirror film. The upper light cavity has a thickness defined by the light emission surface and the light input surface. The thickness is equal to or greater than a distance between adjacent light transmission apertures.

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.
摘要翻译：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。

摘要： Suspended optical film assemblies including a frame, an optical film, and an elastomeric film are disclosed. The elastomeric films include a first attachment region, a second attachment region, and a free region between the first and second attachment regions. The first attachment region is affixed to the frame; the second attachment region is affixed to the optical film, so that the free region is in tension and supports the optical film within the frame. The tension in the elastomeric film free region can help maintain flatness and reduce distortion in the optical film during environmental changes that influence dimensional changes in the frame, optical film, and elastomeric film.
