General description
AS7211 is a networking-enabled IoT smart lighting manager with embedded digital ambient light sensor providing closed-loop and automatic daylighting management. IoT luminaire control is through a network connection, or by direct connection to 0-10V dimmers, with control outputs that include direct PWM to LED drivers or analog 0-10V to standard dimming ballasts. A simple text-based smart lighting command set and serial UART interface, enables easy integration to standard network clients.

Smart Lighting Integration Kit for AS722x/1x
AS7221/20/11/10 Smart Lighting IntegrationKit
The Smart Lighting Integration Kit (SLIK) is a complete color tuning luminaire reference design solution, built around the AS7221 network-enabled smart lighting manager. The kit applies to the full AS72xx smart lighting manager, including the AS7221, AS7220, AS7211, and AS7210. The integration kit is designed to move developers rapidly from demo to proof-of-concept integration into a prototype luminaire design. It consists of two interconnected modules: the AS7221 sensor, networking and power module with integrated Bluetooth Smart (BLE); and the LED module with two strings of white LEDs for tuning (warm and cool). The SLIK includes the 2-section board, a diffuser, USB to serial interface cable, and power supply with US/European adapter. The included memory stick includes complete user documentation, GUI and drivers.

AS7220 CCT and Lumen Maintenance Manager
AS7220
Simplify single or selectable CCT luminaire and replacement lamp designs with the AS7220 calibrated CCT and lumen maintenance smart lighting manager. Closed loop calibrated tri-stimulus color sensing for direct CIE color point mapping and control enables lower precision components to produce a higher-quality single or selectable-CCT luminaire or replacement lamp.
Configurable single CCT lifetime target values are stored at the time of manufacture, allowing the AS7220 to manage independent LED strings to assure consistent CCT over time, temperature, and the full range of dimming. In addition, a selection of industry standard CCT targets can be selected via resistor configuration to enable a single BOM to satisfy multiple CCT SKUs while increasing lifetime color precision. Target lumen output lux-criteria are similarly configurable and are used by the AS7220 to map internal lux to manage LED strings to replace "percent of drive current" with "percent of rated lumen output", for all dimming operations.
Legacy controls are fully supported with direct connection to 0-10V control,. Control outputs include direct PWM management of digital LED drivers or analog 0-10V for standard dimmable drivers.

AS7221 CCT Tuning Smart Lighting Manager
AS7221
Simplify tunable white lighting systems with the AS7221 sensor-integrated IoT smart lighting manager. The AS7221 will lower the manufactured cost of your tunable white lighting system. Closed loop calibrated tri-stimulus color sensing for direct CIE color point mapping and control enables lower precision components to produce a higher-quality tunable white luminaire or replacement lamp. Pre-calibrated to a typical 2 SDCM accuracy, this network enabled chip-scale solution uses a simple text-based smart lighting command set via the serial UART interface to deliver easy integration to standard network clients. Legacy controls are also supported with direct connection to 0-10V controls,. Control outputs include direct PWM management of digital LED drivers or analog 0-10V for standard dimmable drivers.
