1. A lighting arrangement, comprising:
at least one first solid state light source arranged to emit visible light in a wavelength range from 430 to 800 nm,
at least one second solid state light source arranged to emit second light of at least one of violet light and ultraviolet (UV) light in a wavelength range from 315 to 420 nm,
a reflector comprising at least one light-reflecting surface, wherein the reflector at least partially encloses the at least one first solid state light source and the at least one second solid state light source, and wherein at least part of the reflector defines a mixing chamber for mixing at least part of the visible light emitted from the at least one first solid state light source and at least part of the second light emitted from the at least one second solid state light source,
a light exit window, wherein the visible light and the second light mixed by the mixing chamber are arranged to exit the lighting arrangement through the light exit window,
at least one third solid state light source arranged to emit UV light in a wavelength range from 190 to 315 nm, wherein the at least one third solid state light source is arranged outside the mixing chamber, and the at least one third solid state light source is arranged on the light exit window,
a controller configured to individually control the at least one second solid state light source and the at least one third solid state light source, and
the controller further being configured to control one or more properties of the light emitted from the second solid state light source and/or the third solid state light source.
