Combined multicolor LED light sources generate a wide range of colors and correlated color temperatures (CCTs). There are, however, challenges to overcome before such high-quality light sources can be produced. The MD Optical Design Color Management System addresses those challenges. A smart LED driver controls eight channels. Each channel uses smooth-amplitude modulated output signals, thus providing zero-flicker illumination, unlike many existing drivers that use PWM. Using a spectral feedback loop accurately maintains CCT and color point. Possible applications include studio/movie shooting, advertisement panels, color calibration standards for microLED/display manufacturing, paint mixing, automotive paint booths, cosmetics appearance, and exhibition light management.
