Abstract
A light generating system including a first light source configured to generate a first light with a first spectral power distribution, a second light source configured to generate a second light with a second spectral power distribution different from the first spectral power distribution, and optics configured to beam shape at least the first light. The first light has a wavelength range of 380-780 nm, and the second light has a wavelength range of 470-490 nm. The light generating system is configured to provide in a first operational mode white first light in a first direction, and second light in a second direction.
