    • 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。
