    • The invention provides a method and system of controlling illumination characteristics of a plurality of lighting segments. According to the invention, there is provided an illumination system, comprising: a plurality of lighting segments; a detecting subsystem configured to detect an illumination intensity and/or color of lights emitted from each lighting segment; a controller configured to receive the detecting subsystem's output signals representing illumination intensity and/or color of lights emitted from each lighting segment and to generate sets of driving signals to respectively adjust the driving currents of each lighting segment in response to the output signals, so as to adjust the illumination intensity and/or color of the lights emitted from each lighting segment in accordance with a predetermined illumination setting, wherein each set of driving signals has a unique period feature which is distinguished from that of other sets of driving signals corresponding to other lighting segments.

    • This invention relates to an illumination apparatus. The illumination apparatus comprises a light guide plate and a light source configured to emit light into the light guide plate through a first surface, and the light guide plate comprises a concentrator configured to direct incident light in the light guide plate so as to radiate in a direction substantially parallel to a preset plane. The preset plane is perpendicular to any one of the top surface and bottom surface of the light guide plate, and intersects the first surface and a second surface of the light guide plate or intersects the first surface and one of the side surfaces at an angle that is substantially larger than the critical angle of a total reflection. In this way, unwanted light loss in the light guide plate is reduced, and the distribution of the light intensity or luminance along the light guide plate is improved, i.e., a substantially uniform distribution of the light intensity can be achieved.

    • The present invention aims to provide a light guide apparatus based on diffraction gratings. The apparatus comprises a light guide plate (11) comprising a first diffraction grating (13) located on a first surface of or inside the light guide plate (11); a first light source (12), coupled to a first side of the light guide plate (11); wherein the first diffraction grating (11) is configured to extract the light generated by the first light source (12) from the first surface of the light guide plate (11). Since the first diffraction grating (13) is invisibly small, users hardly notice any change of the light guide (11). When the light guide apparatus of the present invention is used as a book reader, the dark area produced when lifting the book reader in a direction away from the objects to be read is smaller than that of existing light guide apparatus based on microstructures, since the light exit angle is relatively small when using a diffraction grating.
    • 本发明的目的在于提供一种基于衍射光栅的导光装置。 该装置包括:导光板(11),其包括位于导光板(11)的第一表面或内部的第一衍射光栅(13); 第一光源(12),耦合到所述导光板(11)的第一侧; 其中所述第一衍射光栅(11)被配置为从所述导光板(11)的所述第一表面提取由所述第一光源(12)产生的光。 由于第一衍射光栅(13)不可见的小,使用者几乎不会注意到光导(11)的任何变化。 当本发明的导光装置用作书本阅读器时,当将书阅读器向远离待读取物体的方向提起时产生的暗区小于现有基于微结构的导光装置的暗区,因为 使用衍射光栅时光出射角度相对较小。
