Ams AS72xx Intelligent Lighting Manager

Ams's AS7211 is a network-enabled smart lighting manager with built-in Digital Ambient Light Sensor (ALS). This provides a single device, closed loop, that automatically adjusts the brightness of fluorescent and LED lights and fixtures to maintain a constant lux response to available daylight. The AS7211 allows for simplified, single-device integration, provides closed-loop and automatic adjustment of LED and fluorescent light brightness and lamp replacement to maintain constant lux response to available daylight. The light response of the AS7211s ALS, combined with an embedded infrared light (IR) blocking filter, produces high-precision Lux readings even in the presence of high infrared sources such as sunlight or nearby incandescent light bulbs. Integrated sensing and control, the AS7211 provides a single device, closed loop and automatically adjusts the brightness of LED and dimmable fluorescent lamps to maintain a constant lux response to available daylight.

The AS7221 is a family of cognitive lighting products that enable lighting to "sense", adapt to its surroundings, and automatically manage lighting to meet aesthetic, quality and energy efficiency needs. The networked Intelligent lighting Manager integrates an embedded, digital, tri-stimulus, true-color, nano-optical sensor that directly provides CIE1931 XYZ and CIE 1976 u 'v 'coordinate mapping for closed-loop, autonomously adjustable variable CCTS and spectrally adjustable LED lights and fixtures.

The AS7225 iot Intelligent Lighting Controller (SLD) integrates an embedded, digital, three-stimulus, color, "calibration life" nanooptical sensor that provides direct mapping of CIE1931 XYZ and CIE 1976 u 'V 'coordinates. The AS7225 White Tunable Director is optimized for color and daylight. This director is ideal for customers who already have a network or control integrated microcontroller (MCU). The adaptive algorithm enables a companion microprocessor to achieve closed loop, autonomous adjustment of variable CCTS and daylight response LED lights and fixtures. With the Smart Lighting controller, users can really adjust the target control.
