Abstract:
A semiconductor light source is disclosed. In an embodiment a semiconductor light source includes at least one semiconductor laser configured to generate a primary radiation and at least one coupling-out element comprising a continuous base region and rigid light guide columns extending away from the base region, the light guide columns acting as waveguides for the primary radiation, wherein the primary radiation is irradiated into the base region during operation, is led through the base region to the light guide columns and is directionally emitted from the light guide columns so that an intensity half-value angle of the emitted primary radiation is at most 90°.
