Itnbecomes a semiconductor light source with a primary radiation source,nwhich in the operation of the semiconductor light source electromagnetic primary radiationnemitted in a first wavelength range, and withna luminescence conversion module into which of the primary radiation sourcenemitted primary radiation is coupled, indicated.nThe luminescence conversion module contains a luminescence conversion element,nwhich by means of a phosphor primary radiationnabsorbed the first wavelength range and electromagnetic secondary radiationnemitted in a second wavelength range. The luminescence conversion elementnis spaced from the primary radiation source at onenHeat sink arranged. It has a reflector surfacenon, passing through the luminescence conversion element, of thisnunabsorbed primary radiation into the luminescence conversion elementnreflected back and / or secondary radiation innDirection of a light output surface of the luminescence conversion elementnreflected. |
