Abstract
Some embodiments include a method of operating a tunable light module. The method can include driving a lamp in the tunable light module, having lamps of at least two colors, to produce a colored light according to the color mixing plan that corresponds to a correlated color temperature (CCT); measuring a light characteristic of the lamp using a light sensor; detecting a degradation level by comparing the measured light characteristic against an expected light characteristic; and adjusting a current level for driving the lamp at the CCT by referencing the color mixing plan and an alternative coefficient corresponding to the degradation level.

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.
A method of operating a computer server comprising:
- receiving a spectral profile of a lamp having degraded in a tunable light module that has multiple lamps of at least two colors;
- re-aligning lamps color space map that has test data of the lamp prior to deployment of the tunable light module with the spectral profile;
- updating a color mixing plan associated with the tunable light module based on the re-aligned lamps color space map by re-optimizing the color mixing plan against a set of performance metric constraints on illumination produced by the lamps of the tunable light module;
- and
- sending the updated color mixing plan destined for the tunable light module.
