Abstract
A light-emitting device, comprising: a radiation source (), which emits radiation having a first wavelength, an optical waveguide (), into which the radiation emitted by the radiation source is coupled, and a converter material (), which converts the radiation transported through the optical waveguide () into light () having a second, longer wavelength. A light-emitting device of this type can have an improved light conversion efficiency.
