Abstract (en)
[origin: WO2022136578A1] The invention relates to a method and an assembly having a luminaire (2) which radiates UV light, radiating the UV light in a main propagation direction, wherein at least one surface (3) which is permanently illuminated by the UV light of the luminaire (2) when the luminaire (2) is switched on has a region (4) coated with a material which absorbs UV radiation, the shape and dimensions of the coated region (4) being selected such that all the UV radiation impinging (4) on the illuminated surface (3) with an irradiation intensity above a limit value impinges on the coated region.
