AS7220 Overview
AS7220 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 device is equipped with an advanced Cognitive Lighting Engine (CLE) to optimize CCT and lumen maintenance and color maintenance via a bination of PWM and/or 0-10V...
AS7220 Key Features
- Accurate maintenance of CCT and daylight responsive lighting
- Calibrated XYZ tri-stimulus color sensing for direct translation to CIE 1931/1976 standard observer color maps
- Lifetime-calibrated sensing with minimal drift over time or temperature
- Filter set realized by silicon interference filters
- Optional user/manufacturer configurable CCT maintenance and/or Lumen maintenance
- If enabled, desired CCT and/or Lumen settings are read by the Cognitive Light Engine and maintained by using spectrally
- patible with standard dimmer controls and
- Directly interfaces to 0-10V dimmer controls and
- Directly interfaces to LED string circuity via PWM outputs
- Built-in PWM generators to dim and control warm/cool luminaire LED strings
