LIGHT GENERATOR SYSTEMS AND METHODS

摘要

A light generating system comprising: a plurality of solid state emitters (SSEs) and a stability control system for controlling the spectral stability of the SSEs. In a particular case, the stability control system ma}' comprise: a power regulator to regulate power supplied to a sub-set of the plurality of SSEs; a constant current circuit connected to the power regulator to provide a constant current to the sub-set of SSEs; a current regulation set point connected to the constant current circuit; and a controller configured to set the regulation set point based on metrology relating to the state of the SSEs.
