Claim 11:
12. A lighting system comprising a plurality of luminaires, each luminaire comprising:
a first type light source configured to emit visible light, the first type light source having a visible light main intensity peak having a maximum intensity in a first direction from the luminaire; and
a second type light source configured to emit ultraviolet, UV, light, the second type light source having a UV light main intensity peak having a maximum intensity in a, transverse, second direction,
wherein the plurality of luminaires are arranged such that the UV light main intensity peaks of the plurality of luminaires substantially overlap, wherein at least a sub portion of the plurality of luminaires comprises a sensor, wherein a sensor of a specific luminaire in the sub portion is configured to measure UV light of a neighboring luminaire, and wherein the specific luminaire comprises a controller configured to control an intensity of UV light emitted from the second type light source of the specific luminaire or an intensity of UV light emitted from the second type light source of the neighboring luminaire based on an output from the sensor.
