Abstract
The invention provides a light generating system (), wherein the light generating system () is configured to generate system light () having a controllable spectral power distribution and intensity, wherein in an operational mode the light generating system () is configured to generate during a first time period P, a first spectral power distribution E, and during a second time period P, later in time than the first period P, a second spectral power distribution E, wherein: (A) the controllable spectral power distribution comprises (a) a first spectral range Λhaving one or more wavelengths in the blue, and having a primary first spectral power SP(P, Λ) during the first time period Pand a secondary first spectral power SP(P, Λ) during the second time period P, (b) a second spectral range Λhaving one or more wavelengths in the green, and having a primary second spectral power SP(P, Λ) during the first time period Pand a secondary second spectral power SP(P, Λ) during the second time period P, and (c) an amber-red spectral range Λhaving one or more wavelengths in the amber-red, and having a primary amber-red spectral power SP(P, Λ) during the first time period Pand a secondary amber-red spectral power SP(P, Λ) during the second time period P; (B) the first spectral power distribution Ecomprises the primary first spectral power SP(P, Λ), the primary second spectral power SP(P, Λ), and the primary amber-red spectral power SP(P, Λ); the second spectral power distribution Ecomprises the secondary first spectral power SP(P, Λ), the secondary second spectral power SP(P, Λ), and the secondary amber-red spectral power SP(P, Λ); (C) the first period Pis selected from of at least part of a day; the second period Pis selected from the range of at least part of a day; (D) SP(P, Λ)>0 Watt, SP(P, Λ)>0 Watt, and SP(P, Λ)>0 Watt; SP(P, Λ>0 Watt, and SP(P, Λ)>0 Watt; SP(P, Λ)/SP(P, Λ)<SP(P, Λ)/SP(P, Λ); SP(P, Λ)/SP(P, Λ)<SP(P, Λ)/SP(P, Λ); and SP(P, Λ)/SP(P, Λ)<SP(P, Λ)/SP(P, Λ).
