AS7225 Calibrated XYZ Chromatic Smart Lighting Director

The AS7225 Smart Lighting Director incorporates an embedded digital tri-stimulus 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.

Features

The benefits and features of this device are listed below: Benefits Features
• Provides accurate external host MCU supervision of variable CCT and spectrally tunable lighting
• Integrated intelligence with XYZ tri-stimulus color sensing for direct translation to CIE 1931 standard observer color map
• Uses accurate XYZ sensed data to provide a host MCU, with its own PWMs, simple to use directives for closed loop tuned LED lighting
• Automatically directs external warm and cool white PWM controlled LED strings for chromatic LED luminaire tuning. Also directs dimming (combined with PWM colo.
