China, November 29, 2016, the world's leading high-performance sensors and analog IC supplier Ai Maisi Semiconductor Corporation (amsAG, Switzerland Stock Exchange ticker symbol: AMS) today announced the industry's first integrated adjustable white Intelligent Lighting Manager - AS7221 . With the AS7221 , lighting manufacturers will be able to quickly integrate high-precision color temperature tuning (or “Kelvin tuning”) into their IoT smart lighting products. The AS7221 versatile architecture includes an I2C expansion interface with IoT sensor hub platform capabilities for sensing functions such as air quality detection, temperature sensing, space occupancy and presence for Internet of Awareness.

The AS7221 is equipped with an industry-first embedded tri-stimulus CIEXYZ color sensor for accurate color sensing by mapping directly to the CIE1931 color space. This intelligent lighting manager is a fully integrated lighting control system that is compatible with standard 0-10V inputs and implements the Internet of Things through standard clients such as Smart Bluetooth, ZigBee or WiFi and a complete intelligent lighting command set. Connection and network control, LED spectral tuning control through direct PWM channel output, creating a high-precision solution. This approach significantly reduces development and integration time compared to the more cumbersome discrete component approach.

The director of LED and lighting research at StrategiesUnlimited, a well-known photonics market research company in the industry, said: “With LEDs making the 'digital lighting revolution' possible, the next step is to integrate the control components directly into the lighting unit. Two key potential elements that are both economical and practical are sensor integration and core integration at the semiconductor device level. This result will lead us to the right path to achieve the long-term vision of the LED lighting industry, that is, to achieve truly controllable and interconnected People-oriented intelligent lighting, comprehensively conveys health and comfort, and improves productivity and efficiency."

AS7221 is Ai Maisi Semiconductor recently introduced a series of intelligent lighting management --CognitiveLighting (perceived lighting)? The first extension products. The AS7221 is packaged in a 5x5 mm LGA package for flexible integration into lighting fixtures and large light source replacements. The device provides precise color point tuning for smooth color temperature conversion of warm and cool white LED strings within the luminaire. In addition to the correlated color temperature and color tuning, AS7221 also supports automatic configuration Ai Maisi semiconductor TSL4531 ambient light sensor, to achieve automatic control of lighting.

Tom Griffiths, senior marketing manager at Amers Semiconductor, said: "Next-generation lighting will have three important features: controllability, adaptability and interconnect architecture. Our new intelligent lighting manager series meets these standards and we can help with lighting Manufacturers develop and deploy tunable luminaires that are economical, accurate, and seamlessly integrated into the Internet of Things to address their immediate time-to-market challenges."

The AS7221 has the following main features:

· Equipped with a three-stimulus XYZ color sensor that can be directly mapped to the CIE color space;

· Equipped with a serial universal asynchronous transceiver that can be easily connected to standard networks and wireless clients;

· A full network support architecture with advanced driverless command set for a range of advanced integrated lighting controls;

·I2C expansion capability to realize IoT sensor center platform function

The AS7221 Spectral Tuning IoT Intelligent Lighting Manager is now in volume production. For more information, please visit or contact
