    • 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).
    • 提供半导体光源,所述半导体光源具有主辐射源(1),当所述半导体光源被操作时,所述主辐射源(1)在第一波长范围内发射电磁主辐射(5),并且具有发光转换模块 ),其中馈送由主辐射源(1)发射的初级辐射(5)。 发光转换模块(2)包含发光转换元件(6),其通过发光材料从第一波长范围吸收主辐射(5)并在第二波长范围内发射电磁次级辐射(15)。 发光转换元件(6)被布置在距离主辐射源(1)一定距离处的散热器(3)上。 它具有反射到发光转换元件(6)的反射器表面(7,71,72),初级辐射(5)通过发光转换元件(6)并且不被其吸收和/或反射次级辐射 15)在发光转换元件(6)的光耦合表面(601)的方向上。
