ams OSRAM AS7221 Network-Enabled Smart Lighting Managers

ams OSRAM AS7221 Network-Enabled Smart Lighting Managers are network-enabled IoT Smart Lighting Managers with embedded tri-stimulus color sensing for direct CIE color point mapping and control. IoT luminaire control is through a network connection or by direct connection to 0V to 10V dimmers. Control outputs include direct PWM to LED drivers and analog 0V to 10V to dimming ballasts. A simple text-based Smart Lighting Command Set and serial UART interface enable easy integration to standard network clients.


  • XYZ tri-stimulus sensor for accurate CCT/spectral control
  • Compatible with standard dimmer, occupancy controls, and ballasts
  • Built-in PWM generator for precise 1% dimming
  • 2.3mm x 2.5mm WLCSP or 4.4mm x 4.5mm LGA packages
  • Networked CCT / spectral tuning management
  • Direct 0-10V inputs/outputs
  • Direct PWM interfaces
  • Choice of compact 20-pin packages


  • Autonomous, networked solid-state lighting manager for variable CCT and daylight harvesting
  • Integrated smart lighting control of variable CCT white lighting solutions
  • Networked lighting systems with IoT sensor expandability
  • Commercial, retail, and residential white/color-changing LED lighting systems
  • Luminaires intended to meet California Title 24 daylighting requirements
