Tunable-white lighting sensor supports closed-loop CCT tuning and daylight compensation

New Products | March 29, 2017

The AS7225 tunable-white lighting smart system sensor just launched by ams lets OEM lighting manufacturers access the company's closed-loop CCT tuning and daylight compensation, while retaining the existing host microprocessor architecture in their smart lighting design.

The result is higher precision, more flexible LED binning, and lower system costs for tunable white lighting systems.

The AS7225 is equipped with the product family’s industry-first embedded tri-stimulus CIE XYZ color sensor to enable precise color sensing with direct mapping to the International Commission on Illumination (CIE) 1931 color space. CCT and daylighting tuning directives are communicated to the host microprocessor via an industry-standard I²C interface, allowing IoT smart lighting manufacturers to avoid costly calibration and tuning algorithm development and reduce time to deployment.

The AS7225 is an extension of ams’ Cognitive Lighting smart lighting manager family. The device comes in a 4.5×4.7mm LGA package for flexible integration into luminaires, light-engines and larger replacement lamps, such as LED linear T-LED products.
