The AS7221 CCT Tuning Smart Lighting Manager device is part of the ams AS722x/1x Smart Lighting Manager/Director family of products that simplify tunable and environmentally responsive lighting designs, enable lights to be “aware” and adapt to their surroundings, and to autonomously serve human-centered lighting and energy conservation needs. The device is equipped with an advanced Cognitive Lighting Engine (CLE) to optimize, chromatic white tuning, daylight harvesting and lumen maintenance via a combination of PWM and/or 0-10 V controls with dimming ballasts. Direct connection to a local I/O network enables connectivity with standard occupancy sensors, dimmers or communications bridges.
