Abstract
The invention provides a light generating system (1000) configured to generate system light (1001), wherein the light generating system (1000) comprises a first light generating device (110), wherein: (A) the first light generating device (110) comprises a first light source (10) and a first luminescent converter (210); (B) the first light source (10) comprises a solid state light source, wherein the first light source (10) is configured to generate first light source light (11) having a first light source centroid wavelength (λs,1) selected from the range of 380-420 inn; (C) the first luminescent converter (210) is configured to convert at least part of the first light source light (11) into first converter light (211) having a first converter centroid wavelength (λc, 1) selected from the green-yellow wavelength range; (D) the first light generating device (110) is configured to generate first device light (111) having a spectral power distribution in the wavelength range of 380-780 nm with at least 60% of the spectral power provided by the first light source light (11) and at maximum 40% of the spectral power provided by the first converter light (211).
