    • 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),该导光板包括位于导光板(11)的内表面或内部的第一衍射光栅(13); 耦合到所述导光板(11)的第一侧的第一光源(12); 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,所以用户几乎不注意到光导(11)的任何变化。 当将本发明的导光装置用作书本阅读器时,在远离被读取物的方向提升书本阅读器时产生的暗区比现有的基于微结构的导光装置小,因为 当使用衍射光栅时,光出射角相对较小。

    • The invention relates to a Luminescent Solar Concentrator system (400) and a method for collecting and concentrating external light, particularly sunlight (?1, ?2). The external light is collected by a luminescent converter component (410) having a thickness D and a ratio R = ax/ac between the absorption coefficient ax for sunlight and the reabsorption coefficient ac for luminescence light. Due to the luminescent material comprised by said converter component (410), at least a part of the external light is converted into luminescence light. Moreover, light propagating within the converter component (410) is extracted from it at light extraction sites (EX) having distances W = 0.1·R·D from each other. Light extraction components may for example comprise slanted mirroring surfaces (414) and/or optical elements in contact to the converter component.
    • 本发明涉及一种发光太阳能集中器系统(400)以及用于收集和集中外部光,特别是阳光(λ1,λ2)的方法。 外部光由具有厚度D的发光转换器部件(410)和用于太阳光的吸收系数ax与发光的再吸收系数ac之间的比率R = ax / ac的发光转换器部件(410)收集。 由于由所述转换器部件(410)包括的发光材料,外部光的至少一部分被转换为发光。 此外,在距离为W = 0.1·R·D的光提取位置(EX)处,从转换器部件(410)中传播的光被提取。 光提取部件可以例如包括与转换器部件接触​​的倾斜镜面(414)和/或光学元件。

    • It is disclosed a light-emitting device (200) comprising at least one light guide (202), an optical coupler and at least one light-emitting diode, LED (201). The optical coupler is adapted to optically couple the at least one LED (201) to at least one input surface portion (202a) of the at least one light guide (202). The optical coupler may comprise at least one light-angle selecting transflector (203). The at least one light guide (202) comprises at least one outcoupling element adapted to couple out light from the light guide (202) such that at least some of the light outputted from the light guide (202) has an intensity having a predetermined angular distribution with respect to a surface normal of the at least one LED (201). By such a configuration, one or more LEDs (201) and additional optics may be provided in an integrated solution that may relatively easily be assembled and maintained in a desired position relatively each other. Such an integrated solution may be relatively thin and compact in comparison with known devices.
