  • Patent number: 10170453
    Abstract: The invention relates to an arrangement for generating mixed light, which comprises three semiconductor chips, emitting in the blue spectral range, of three devices. Arranged in the light paths of the individual semiconductor chips are different conversion elements which are configured to convert primary radiation into secondary radiation. The total radiation (S1, S2, S3) exiting the respective devices (10, 20, 30) has a corresponding chromaticity coordinate on the black body curve of the CIE color diagram 1931 or lies within a color quadrilateral of the CIE color diagram.
