Abstract
A light system, wherein a first device that partly converts radiation of a first group is disposed in front of a portion of the first group, wherein the first device includes a phosphor-containing layer that converts a portion of primary radiation into secondary radiation having a longer wavelength, wherein the second group emits radiation having a greater wavelength than the first group, a second device that partly converts primary radiation of the first group, the second device being in front of a portion of the first group, wherein a converter exhibits a temperature dependence based on a different temperature dependence of the refractive index of a phosphor and a matrix embedding the phosphor, and the phosphor and matrix have at room temperature a difference in the refractive index is small and at operating temperature the difference in the refractive index is at least 1.5 times that at room temperature.
