    • This invention relates to a device for determining the conversion power of conversion element, a method for performing these measurements and a method for producing pcLEDs with essentially the same color point applying said device and said method. The device comprises a light source (5), a sample holder (6) and a detector element (7), wherein the light source (5) illuminates the sample holder (6) with a primary light (41), the sample holder (6) is at least locally transparent for a primary light (41), suitable to mount the multitude of conversion elements (3) capable to partly convert the primary light (41) into a secondary light (42), and comprises suitable prevention means (62, 62a, 62b, 62c, 62d, 62e) to prevent a light guiding of the secondary light (42) from one mounted conversion element (3) through the sample holder (6) to another mounted conversion element (3), and the detector element (7) is suitable to measure the intensities of primary and secondary light (41, 42) for each conversion element (3) separately.
    • 本发明涉及一种用于确定转换元件的转换功率的装置,一种用于执行这些测量的方法,以及一种基本上具有相同色点的pcLED的应用所述装置和所述方法的方法。 该装置包括光源(5),样本保持器(6)和检测器元件(7),其中光源(5)用初级光(41)照射样品架(6),样品架 6)对于初级光(41)至少是局部透明的,适于安装能够将初级光(41)部分地转换成二次光(42)的多个转换元件(3),并且包括合适的防止装置 62,62a,62b,62c,62d,62e),以防止二次光(42)从一个安装的转换元件(3)通过样品保持器(6)到另一个安装的转换元件(3)的引导, 检测器元件(7)适合于分别测量每个转换元件(3)的初级和次级光(41,42)的强度。
