    摘要: 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).
