Patent ID: 8410507

Claim:
A luminous means, comprising: at least one optoelectronic semiconductor device which emits electromagnetic radiation during operation at at least one first wavelength and at at least one second wavelength, the first wavelength is around 430 nm and the second wavelength is around 470 nm, with a tolerance of 10 nm in each case; and at least one conversion means which converts the first wavelength at least partly into radiation having a different frequency, wherein a radiation spectrum emitted by the luminous means during operation is metameric with respect to a black body spectrum, wherein the second wavelength is at smaller wavelengths than a main operating range of the conversion means, and wherein the conversion means converts a proportion of at least 50% of the first wavelength into a radiation having a different wavelength, said proportion being at least 5 percent greater than a corresponding proportion of the second wavelength.
