A semiconductor light source is provided, the semiconductor light source having a primary radiation source ( 1 ) which, when the semiconductor light source is operated, emits electromagnetic primary radiation ( 5 ) in a first wavelength range, and having a luminescence conversion module ( 2 ) into which primary radiation ( 5 ) emitted by the primary radiation source ( 1 ) is fed. The luminescence conversion module ( 2 ) contains a luminescence conversion element ( 6 ) which, by means of a luminescent material, absorbs primary radiation ( 5 ) from the first wavelength range and emits electromagnetic secondary radiation ( 15 ) in a second wavelength range. The luminescence conversion element ( 6 ) is arranged on a heat sink ( 3 ) at a distance from the primary radiation source ( 1 ). It has a reflector surface ( 7, 71, 72 ) which reflects back into the luminescence conversion element ( 6 ) primary radiation ( 5 ) which passes through the luminescence conversion element ( 6 ) and is not absorbed thereby and/or reflects secondary radiation ( 15 ) in the direction of a light coupling-out surface ( 601 ) of the luminescence conversion element ( 6 ). |
