AS7220 Lumen/Color Maintenance Manager

Standalone Color/Lux Sensing and Integrated Luminaire Management

AS7220 is a highly-integrated Smart Lighting Manager with embedded tri-stimulus color sensing for direct CIE color point mapping. This provides single-device, closed-loop and automatic lock lumen output and CCT/color points for LED lamps and luminaires to enable long term lamp stability and lumen/color accuracy. For streamlined system integration, luminaire control is through direct connection to 0-10V dimmers, with control outputs that include direct PWM to LED drivers and analog 0-10V for simplified dimming.
