Claim of US Patent No. 9,648,696

1. A computer-implemented method of operating a model builder system for enabling recalibration of a tunable light system,
comprising:
generating a color mixing plan for a tunable light module having multiple lamps of at least two colors, wherein the color
mixing plan includes coefficients used to determine how to drive each of the lamps to produce an output illumination of the
tunable light module, the coefficients associated with the output illumination having a particular color characteristic;

selecting a constraint of a performance metric of illumination produced from the tunable light module;
estimating a degradation level of a lamp in the tunable light module;
computing alternative coefficients for the color mixing plan for the estimated degradation level based on at least the constraint;
and

storing the alternative coefficients, associated with the estimated degradation level, in the tunable light module.
