일반 설명
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.

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.

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.
TSL25721 Ambient Light Sensor
TSL25721
TSL2572 device family provides ambient light sensing (ALS) that approximates human eye response to light intensity under a variety of lighting conditions and through a variety of attenuation materials. Accurate ALS measurements are the result of TAOS’ patented dual-diode technology and the UV rejection filter incorporated in the package. The operating range can be extended to 60000 LUX when the low-gain mode is use. The TSL2572 device is particularly useful for enabling automatic brightness control (ABC) in large LCD flat-panel TVs and displays by providing optimum viewing in diverse lighting conditions (daytime versus nighttime viewing) while significantly reducing energy consumption to meet the stringent ENERGY STAR requirements.
