    Abstract: A luminous means (1) including at least one optoelectronic semiconductor device (2) which emits electromagnetic radiation during operation at at least one first wavelength (L1) and at at least one second wavelength (L2), wherein the first wavelength (L1) and the second wavelength (L2) differ from one another and are below 500 nm, in particular between 200 nm and 500 nm. Furthermore, the luminous means (1) includes at least one conversion means (3) which converts the first wavelength (L1) at least partly into radiation having a different frequency. The radiation spectrum emitted by the luminous means (1) during operation is metameric with respect to a black body spectrum. Such a luminous means makes it possible to choose the first wavelength and the second wavelength in such a way that a high color rendering quality and a high efficiency of the luminous means can be realized simultaneously.
