Claim Text:
1. Method for providing a light output from a lighting system capable of emitting light within a lighting system color gamut in an x-y color plane, comprising the steps of: receiving a light output target comprising a target color point and a target flux; comparing said target color point with said lighting system color gamut; and if said target color point is outside of said color gamut: determining a first approximation color point inside said color gamut based on a minimization of a distance in said x-y color plane between said target color point and said first approximation color point; determining a highest possible flux achievable by said lighting system at said first approximation color point; if said highest possible flux achievable by the lighting system at said first approximation color point is equal to or larger than said target flux, control said lighting system to provide light defined by said first approximation color point and said target flux; and if said highest possible flux achievable by the lighting system at said first approximation color point is lower than said target flux, determining a second approximation color point at which said lighting system is capable of providing said target flux based on a minimization of a distance in said x-y color plane between said first approximation color point and said second approximation color point; and controlling said lighting system to provide light defined by said second approximation color point and said target flux.
