Ams Launches AS7221 Smart Lighting Manager
Ams AG, a provider of sensors and analog ICs, has announced the AS7221, which the company calls the industry's first integrated white-tunable smart-lighting manager. Lighting manufacturers designing products with the AS7221 can quickly integrate high-precision CCT capabilities into their Internet of Things smart-lighting offerings. The system's architecture, which includes an I2C extension interface, enables the AS7221 to provide 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 precise 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 and Wi-Fi. LED control for spectral tuning is implemented via direct PWM channel outputs, the company reports, resulting in a high-precision solution that slashes development and integration times compared with more bulky discrete component approaches.

"With LEDs having enabled the digital lighting revolution, the next logical step is to control integration directly into the luminaires," said Philip Smallwood, the director of LED and lighting research for photonics market research firm Strategies Unlimited, in a prepared statement. "Two potential keys to that move, which make it both practical and cost-effective, are sensor fusion and core integration at the semiconductor device level. The result will take us right down the path of realizing the LED lighting industry's long-standing vision of truly controllable, connected and human-centered smart lighting that will deliver well-being, productivity and efficiency benefits across the board."

The AS7221 is the first extension to ams' recently announced Cognitive Lighting smart-lighting manager family. The compact AS7221 will be available in a 5-millimeter by 5-millimeter LGA package, the company reports, for flexible 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, the AS7221 includes automatic configuration support for ams' TSL4531 ambient light sensor for turnkey daylighting capabilities.

"The next generation of lighting will be defined by three key characteristics: controllability, adaptation and connected architectures," said Tom Griffiths, ams' senior marketing manager, in the prepared statement. "Our new family of smart lighting managers meet those criteria. With this latest entry, we are addressing the luminaire manufacturers' critical time-to-market challenge for developing and deploying a spectrally tunable luminaire that is cost-effective and accurate, and which smoothly integrates into the Internet of Things."

Key features include a tri-stimulus XYZ color sensor for direct mapping into the CIE color space; a serial UART for simple connection to standard networks and wireless clients; a fully network-enabled architecture with a high-level, driverless command set for an array of integrated luminaire controls; and I2C expansion capability, to enable IoT sensor-hub platform functionality.

Pricing for the AS7221 Spectral Tuning IoT Smart Lighting Manager is set at $3.13 each in quantities of 10,000 pieces, and the system is also available in production volumes. Additional information is available at the company's website, at by contacting
