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 () 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.

Arrangement and method for generating mixed light

An illumination device includes a number of radiation reflectors that are each irradiated by at least one light source. The radiation reflectors are shaped in such a way that they can be combined modularly to form a radiation-reflecting luminous area.

Illumination device with radiation reflectors arranged modularly to form a radiation-reflecting luminous area

A lighting apparatus comprising a plurality of light modules is specified, wherein each light module includes a plurality of groups of light sources mounted on a circuit board of said light module, and said light modules are arranged in rows on a carrier of said lighting apparatus. A display device comprising such a lighting apparatus is also specified.
