Abstract:
The invention provides a lighting system (1000) configured to provide lighting system light (1001), the lighting system (1000) comprising: —a first light source (10) configured to generate first light source light (11) having an emission band with a peak wavelength selected from the range of 380-420 nm; —a second light source (20) configured to generate second light source light (21), spectrally different from the first light source light (11), having an emission band with a peak wavelength selected from the range of 425-440 nm; —a third light source (30) configured to generate third light source light (31), spectrally different from the first light source light (11) and from the second light source light (21), having an emission band with a peak wavelength selected from the range of 445-465 nm; —a luminescent material (200) configured to convert part of one or more of the first light source light (11), the second light source light (21), the third light source light (31), and optional fourth light source light (41) of an optional fourth light source (40), into luminescent material light (201) having an emission with one or more emission wavelengths selected from the range of 530-700 nm; and —a control system (160) configured to control the lighting system light (1001), wherein the lighting system light (1001) comprises one or more of the first light source light (11), the second light source light (21), the third light source light (31), and the luminescent material light (201).
