Abstract

One embodiment of the invention proposes a light-emitting device comprising a radiation source for the emission of a radiation having at least a first wavelength, and an elongated, curved light-guiding body, into which the radiation emitted by the radiation source is coupled and which couples out light at an angle with respect to its longitudinal axis on account of the coupled-in radiation having the first wavelength.
