ams announces AS7221 smart lighting manager

November 30, 2016 -- ams announced the AS7221, an integrated white-tunable smart lighting manager. Lighting manufacturers designing with the AS7221 can now integrate CCT, or “Kelvin-tuning”, capabilities into their Internet of Things (IoT) smart lighting offerings. The architecture, which includes an I2C extension interface, positions the AS7221 to deliver Internet of Awareness IoT sensor hub platform capabilities for sensing functions such as air quality, temperature, occupancy, and presence.

The AS7221 is equipped with an embedded tri-stimulus CIE XYZ color sensor to enable color sensing with direct mapping to the CIE 1931 color space. This smart lighting manager is a fully integrated luminaire control system, compatible with standard 0-10V inputs and enabled for IoT connectivity and network control through standard clients such as Bluetooth Smart, ZigBee or WiFi, through a complete Smart Lighting Command Set. LED control for spectral tuning is implemented via direct PWM channel outputs.
The AS7221 is the first extension to ams’ recently announced Cognitive Lighting smart lighting manager family. The AS7221 will be available in a 5x5mm LGA package, for integration into both luminaires and larger replacement lamps. The device provides precise color point tuning, smoothly controlling CCT transitions between configured warm and cool white LED strings within a luminaire.  In addition to the color- and CCT-tuning functions, the AS7221 includes automatic configuration support for ams’ TSL4531 ambient light sensor for turnkey daylighting capabilities.

Key features of the AS7221 include:

  • Tri-stimulus XYZ color sensor for direct mapping into the CIE color space
  • Serial UART for simple connection to standard networks and wireless clients
  • Fully network-enabled architecture with high-level, driverless command set for a wide array of advanced integrated luminaire controls
  • I2C expansion capability to enable IoT sensor-hub platform functionality
