Calibrated CCT and Lumen Maintenance Smart Lighting Manager
The AS7220 Smart Lighting Manager™ is part of the ams Cognitive Lighting family of products that enable lights to autonomously adapt to human lighting and energy conservation needs. The AS7220 includes an advanced Cognitive Lighting Engine (CLE) to optimize CCT and lumen maintenance and color maintenance via a combination of PWM and/or 0-10V controls with dimming ballasts. Configurable single CCT lifetime target values are stored by the luminaire manufacturer within the attached flash EPROM, or are selectable using an I2C port expander. Target lumen output lux-criteria are similarly configurable and are used by the AS7220 to correlate internal lux to manage PWM mapping to allow automatic compensation for lumen output to be maintained over the life of the light.
CIE Tri-Stimulus XYZ chromatic white/color sensing provides accurate CCT measurement to allow closed loop compensation to the preset target. The AS7220 is delivered fully calibrated, while the integrated intelligence enables lifetime CCT calibration to within 2-4 Macadam steps.
Autonomous, solid-state lighting manager for long term color point and lumen maintenance.
