Abstract
System(s), apparatus(es), and method(s) are provided for control of quality of light emitted from a group of solid-state light (SSL) sources that are part of an illumination fixture. The control is based at least in part on regulation of the spectral power distribution (SPD) of the light to match a SPD of a reference light source. A spectroscopic analyzer collects electromagnetic (EM) radiation emitted from the group of SSL sources and EM radiation substantially emitted from the reference light source. A first controller analyzes spectroscopic data related to SPDs of the group of SSL sources and the reference light source and, based on the analysis issues a configuration of the group of SSL sources. Implementation of the configuration causes the group of SSL sources to emit EM radiation with a SPD that nearly matches the SPD of the EM radiation substantially emitted from the reference light source.
