Abstract
A lighting system includes multiple light sources, a sensing unit, and a control system. The light sources have different emission spectra, and the sensing unit is configured to measure a spectral content of light. The control system may be configured to use measurements from the sensing unit to select respective intensities for emissions from the light sources and then independently control the light sources to emit the respective intensities. In particular, the control system can select and render a spectral distribution selected based on the light reflected from objects that are being illuminated or render a spectral distribution to supplement light from other light sources and achieve a lighting objective.
