    摘要： It is disclosed a light-emitting device (100) comprising a light guide (101), comprising a first (101a) and a second (101b) output surface portion. The light-emitting device (100) further comprises a plurality of light-outcoupling elements (103) and an array of beam-forming structures (104). The light-outcoupling elements (103) are positionally arranged relatively to the beam-forming structures (104) such as to enable light that is impinging on at least one of the light-outcoupling elements (103) and subsequently being incident on a surface portion of a beam-forming structure (104) to be within a predetermined angle interval with respect to the surface portion. Each of the beam-forming structures (104) is adapted to enable light leaving a surface portion of the beam-forming structure (104) to be within a predetermined angle interval with respect to the surface portion. Both direct, functional light and indirect light may be provided, an increased optical efficiency may be achieved, glare control properties of the light outputted from the light-emitting device (100) may be improved and/or the ratio of light outputted from the first surface portion (101a) of the light guide (101) to light outputted from the second surface portion (101b) of the light guide (100) may be adjusted.

    摘要： Proposed is a light emitting apparatus (1) comprising a light source (5) for emitting light and a collimator (40) for arranging the light emitted in an application specific distribution. The light source comprises (i) a semiconductor device (10) capable of emitting light, (ii) a body (20) having a bottom surface (21) adjacent to the semiconductor device (10) and an opposing top surface (22), and (iii) a reflector (30) positioned adjacent the top surface (22). The light emitting apparatus (1) is characterised in that the reflector (30) has a surface larger than the bottom surface (21) of the body (20). This is especially advantageous for creating a given light beam collimation with a smaller collimator or alternatively for creating a collimator producing a significantly narrower light beam.

    摘要： The invention relates to a backlighting system (10, 11, 12, 13, 14, 15, 16) and to a display device. The backlighting system comprises a plurality of segments (20, 21, 22, 23, 24) for selectively illuminating a predefined area of pixels of a display device. The backlighting system is configured for selectively controlling the intensity and/or color of the light emitted from the segment, each segment comprising a light source (30). The backlighting system (10, 11, 12, 13, 14, 15, 16) further comprises light barriers (40) for limiting the lateralspreading of the light emitted by the light source (30) towards the neighboring segments (20, 21, 22, 23, 24). The light barriers define grid-lines of a grid, and the light source (30) is arranged at a position on the grid-line which at least partially coincides with at least one of the light barriers. The effect of the measures according to the invention is that by positioning the light source of the segment on the same grid-line as the light barriers, the light from the light source spreads on either side of the light barrier towards the neighboring segments. This enables a predefined overlap of the light emitted by the segment towards its neighboring segments without the need for additional thickness of the backlighting system.

    摘要翻译： 本发明涉及背光系统（10,11,12,13,14,15,16）和显示装置。 背光系统包括用于选择性地照亮显示装置的预定区域的像素的多个段（20,21,22,23,24）。 背光系统被配置为选择性地控制从片段发射的光的强度和/或颜色，每个片段包括光源（30）。 背光系统（10,11,12,13,14,15,16）还包括光栅（40），用于限制由光源（30）发射的光朝向邻近片段（20,21,22）的边缘 ，23,24）。 光栅限定栅格的栅格线，并且光源（30）被布置在至少部分地与至少一个光栅重合的网格线上的位置。 根据本发明的措施的效果是通过将光源的光源定位在与光栅相同的格栅线上，来自光源的光在光栅的任一侧向邻近的片段扩散。 这使得能够将段发射的光预定重叠到其相邻的段，而不需要背光系统的额外厚度。
