摘要:
A lighting assembly (1000), a lamp and a luminaire are provided. The lighting assembly comprises a first light source (110), a second light source (108) and an UV filter (104). The first light source emits in operation visible light (112). The second light source emits in operation UV light (108). The UV filter allows a transmission of visible light and absorbs or reflects UV light. The UV filter is arranged in an optical path from the second light source towards the first light source to prevent the UV light to impinge on the first light source while allowing the emission of the UV light into the ambient of the lighting assembly.
