1. A disinfection lighting device comprising:
a first light source, wherein the first light source comprises a solid-state light source, wherein the solid-state light source comprises one or more light emitting diodes, lasers and/or superluminescent diodes; wherein the first light source is configured to generate first light source light having a first spectral power distribution, wherein the first spectral power distribution comprises first light source light in the UV wavelength range and/or visible wavelength range;
a second light source, wherein the second light source is configured to generate second light source light having a second spectral power distribution different from the first spectral power distribution, wherein the second spectral power distribution comprises second light source light in the UV wavelength range,
wherein the second light source is arranged at a distance D from the first light source, the second light source comprises a light input face configured in a light receiving relationship with the first light source, and the second light source comprises a light exit face,
wherein the second light source is transmissive for at least (a major) part of the first light source light; and
wherein the disinfection lighting device is configured to generate lighting device light emanating from the light exit face and comprising the second light source light and the first light source light,
wherein the disinfection lighting device comprises a light exit window, wherein the light exit face is the light exit window.
