A light radiating semiconductor constructional element comprises: (i) a semiconductor body (1) having a series of semiconductor layers giving out an electromagnetic radiation of wavelength lambda not greater than 520 nm; (ii) first and second electrical connections (2,3) connected to the semiconductor body (1); and (iii) a luminescence conversion element. The conversion element converts radiation of a first spectral partial region of radiation originating from a first wavelength region into radiation of a second wavelength region. The semiconductor constructional element gives out radiation from a second spectral partial region of first wavelength region and radiation of second wavelength region.
