摘要： A light emitting device includes a radiation source for the emission of electromagnetic radiation and a converter element on which the electromagnetic radiation impinges in a first surface region and which, excited by the impinged electromagnetic radiation, emits visible light into an environment in a second surface region which differs at least partially from the first surface region. The wavelength of the light emitted into the environment differs from the wavelength of the electromagnetic radiation impinged on the converter element. The converter element includes a luminous element including a textile with a converter material. The converter material due to excitation by the electromagnetic radiation with a first wavelength emits visible light with a second wavelength differing from the first wavelength. The radiation source realizes a background illumination for the converter element. The first surface region is formed by a side surface or a back surface of the converter element.
