Abstract
A 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 () the target color point with the lighting system color gamut (); and if the target color point is outside of the color gamut: determining () a first approximation color point () inside the color gamut based on a minimization of a distance in the x-y color plane between the target color point and the first approximation color point; determining () a highest possible flux achievable by the lighting system at the first approximation color point; if the highest possible flux achievable by the lighting system at the first approximation color point is equal to or larger than the target flux, control () the lighting system to provide light defined by the first approximation color point and the target flux; and if the highest possible flux achievable by the lighting system at the first approximation color point is lower than the target flux, determining () a second approximation color point () at which the lighting system is capable of providing the target flux based on a minimization of a distance in the x-y color plane between the first approximation color point and the second approximation color point; and controlling () the lighting system to provide light defined by the second approximation color point and the target flux.
