Abstract
The invention provides a light generating system () configured to generate in a first operational mode of the light generating system () system light (), wherein: the system light () in the first operational mode has a spectral power distribution with at least 85% of the spectral power in three emission bands () comprising (i) a first emission band () having a centroid wavelength of 445 nm +/−25 nm and having a full width half maximum of at maximum 25 nm, (ii) a second emission band () having a centroid wavelength of 541 nm +/−25 nm and having a full width half maximum of at maximum 150 nm, and (iii) a third emission band () having a centroid wavelength of 614 nm +/−25 nm and having a full width half maximum of at maximum 25 nm; in the first operational mode the light generating system () is configured to control the spectral power distribution of the system light () in dependence of a radiant flux of the system light () while maintaining a correlated color temperature of the system light () within +/−10% of a predetermined correlated color temperature value; and in the first operational mode the light generating system () is configured to shift a color point () of the system light () towards a lower Dwith decreasing radiant flux of the system light () or to shift the color point () of the system light () towards a higher Dwith increasing the radiant flux of the system light ().
