Claim 12:
13. The lighting system according to claim 12, wherein the first type light source and the second type light source is a solid-state light source such as a light-emitting diode, LED and/or a laser diode, and
wherein each luminaire, further comprising a reflector frame forming at least a part of a perimeter of an inner space essentially extending in an x-y plane, according to a cartesian coordination system having x, y, and z vectors, wherein the vector z is in the first direction, wherein the second type light source is arranged to emit UV light into said inner space in plane with said x-y-plane, wherein the UV light main intensity peak has its maximum intensity in a direction towards a remotely arranged location across said inner space, at said location said UV light is:
i) absorbed by a beam dump; or
ii) reflected by a first part of the reflector frame back across said inner space to either a second part of the reflector frame or to a beam dump; or
iii) reflected multiple times back and forth from said first part to said second part and from said second part to further parts of the reflector frame, optionally finally being reflected towards said beam dump.
