    摘要: 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.

    摘要: Electroluminescence light source having a transparent substrate (2), an electroluminescent layer structure for emitting light throughthe substrate, a first light outcoupling layer (3) arranged between substrate and electroluminescent layer structure for producing a non-uniform angular distribution of the light upon entry of the light into the substrate (2), and a second light outcoupling layer (1) arranged above the substrate (2) when viewed in the direction of propagation of light (7), with a surface structure adapted to the non-uniform angular distribution of the light for the effective light outcoupling from the electroluminescence light source.
