Abstract
The invention provides a light generating system () comprising one or more primary solid state light sources (), one or more secondary solid state light sources (), a first luminescent material arrangement (), a second luminescent material arrangement (), and a control system (), wherein: (A) the one or more primary solid state light sources () are configured to generate primary light (); (B) the one or more secondary solid state light sources () are configured to generate secondary light (); (C) the first luminescent material arrangement () is configured in a light receiving relationship with at least one primary solid state light source () and is configured to convert at least part of the primary light () of the at least one primary solid state light source ()) into first luminescent material arrangement light (); wherein when the at least one primary solid state light source () alone irradiates the first luminescent material arrangement () a first spectral power distribution, comprising the primary light () (of the at least one primary solid state light source ()) and the first luminescent material arrangement light (), is obtained; (D) the second luminescent material arrangement () is configured in a light receiving relationship with at least one (other) primary solid state light source () and is configured to convert at least part of the primary light () into second luminescent material arrangement light (); wherein when the at least one (other) primary solid state light source () alone irradiates the second luminescent material arrangement () a second spectral power distribution, comprising the primary light () and the second luminescent material arrangement light (), is obtained; (E) the first spectral power distribution and the second spectral power distribution have v' values differing at least 0.02; wherein the first spectral power distribution has a first color point outside 10 standard deviation of color matching (SDCM) from the black body locus, and wherein the second spectral power distribution has a second color point outside 10 standard deviation of color matching (SDCM) from the black body locus.
