    摘要： An electroluminescence device includes at least one electroluminescence light source for emitting a primary radiation, such as having wavelengths between 200 nm and 490 nm, and at least one light-converting element, arranged in the path of the rays of the primary radiation, for partial absorption of the primary radiation and emission of a secondary radiation. The light-converting element has a dilatation or expansion in the radiation direction of the primary radiation, which is less than an average scattering length of the primary radiation in the light-converting element.
