The AS7225 is designed for use directly in tunable white luminaires, replacement lamps (bulbs) and light-engines/modules. The AS7225 Smart Lighting Director incorporates an embedded digital tristimulus chromatic calibrated for life nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping. Adaptive algorithmic support enables a companion microprocessor to implement closed-loop, autonomous adjustment of variable CCT and daylight responsive LED lamps and luminaires. The AS7225 arrives pre-calibrated, and is designed for rapid integration into white-tunable and daylight responsive luminaire designs, delivering directives to the local microprocessor via an industry-standard I²C bus or UART interface.
