Abstract
A light-emitting device includes at least one first light-emitting semiconductor component, which radiates red light during operation, at least one second light-emitting semiconductor component having a wavelength conversion element, and at least one third light-emitting semiconductor component having a wavelength conversion element. The second and third light-emitting semiconductor components each radiate blue primary light and converted secondary light and the respective superposition of the primary light and the secondary light of the second and third light-emitting semiconductor components has different chromaticity coordinates.
