Abstract

A semiconductor component has a semiconductor chip that generates an electromagnetic primary radiation having a first peak wavelength, having a first conversion element, which has a quantum structure, wherein the quantum structure is formed to partially shift the primary radiation to a secondary radiation having a second peak wavelength, wherein a second conversion element is provided which has a luminescent material, wherein the luminescent material is formed to shift an electromagnetic radiation to a tertiary radiation having a dominant wavelength, wherein the first conversion element is formed to generate secondary radiation, which has a lower peak wavelength than the dominant wavelength of the tertiary radiation.
