Abstract:
1. A light-radiating semiconductor component comprising a semiconductor body having a semiconductor layer sequence comprising layers based on GaN and configured to emit electromagnetic radiation of a first wavelength range during operation of the semiconductor component; and a luminescence conversion element comprising at least one luminescent material, wherein the first wavelength range comprises at least light from the blue spectral range and the luminescence conversion element is operable to convert some electromagnetic radiation from the first wavelength range into light of at least one second wavelength range, different from the first wavelength range, in such a way that the semiconductor component emits white light, the white light being composed of visible light of the first wavelength range and of visible light of the at least one second wavelength range and having a spectrum, which spectrum has a first relative intensity peak in the blue spectral range, has a second relative intensity peak at a wavelength between 500 nm and 600 nm, and extends at least to a wavelength of 700 nm with a full-width half-maximum (FWHM) for the second relative intensity peak of at least about 80 nm, the light-radiating semiconductor component further comprising: a first transparent encapsulation directly covering the semiconductor layer sequence, wherein the luminescence conversion element is a luminescence conversion layer applied directly on the first transparent encapsulation; and a second transparent encapsulation directly covering the luminescence conversion layer.
