1. A light emitting device, comprising:
at least one radiation source for the emission of electromagnetic radiation having a first wavelength, and
a converter element on which the electromagnetic radiation impinges in a first surface region of the converter element and which, when excited by the impinged electromagnetic radiation, emits visible light having a second wavelength different from the first wavelength into an environment by way of a second surface region of the converter element which is different from the first surface region,
wherein
the converter element comprises at least two luminous elements comprising a first luminous element and a second luminous element,
each of the at least two luminous elements comprises a yarn, twine and/or rope,
the yarn, twine and/or rope of the first luminous element is coated or impregnated with a first converter material,
the yarn, twine and/or rope of the second luminous element is coated or impregnated with a second converter material,
in response to being excited by the electromagnetic radiation having the first wavelength, the first luminous element and the second luminous element respectively emit visible light having different colors that mix to form the visible light emitted by the converter element into the environment,
the radiation source realizes a background illumination for the converter element,
the first surface region is formed by a back surface of the converter element, and
the second surface region is a visible surface of the light emitting device that faces away from the radiation source.
