Abstract: The invention relates to a luminaire (100) that can simultaneously be used for disinfection and for illumination. The luminaire (100) comprises a light engine (120) located in a housing, and an optical component (130) for receiving a light output of the light engine (120). The light engine (120) has a first light source (121) for emitting visible light and a second light source (122) for emitting ultraviolet radiation. The input side (131), the output side (132), and the wall structure (133) together delimit an interior volume of the optical component (130). The input side (131), the output side (132) and the interior volume of the optical component (130) are transmissive for visible light and for ultraviolet radiation. The wall structure (133) of the optical component (130) is transmissive for visible light and non-transmissive for ultraviolet radiation. The optical component (130) has a wall structure (133) separating an input side (131) and an output side (132). The input side (131), the output side (132) and an interior volume of the optical component (130) are transmissive for visible light and for ultraviolet radiation, while the wall structure (133) of the optical component (130) is transmissive for visible light and non-transmissive for ultraviolet radiation.
