AS7225 Description
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 panion microprocessor to implement closed-loop, autonomous adjustment of variable CCT and daylight responsive LED lamps and luminaires. The AS7225 arrives pre-calibrated, and is...
AS7225 Key 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 m
- Uses accurate XYZ sensed data to provide a host MCU, with its own PWMs, simple to use directives for closed loop tuned L
- Automatically directs external warm and cool white PWM controlled LED strings for chromatic LED luminaire tuning. Also d
- Automatic spectral and lumen maintenance over temperature and time
- Supports autonomous color point and lumen output adjustment resulting in automatic spectral and lumen maintenance
- General Description
- Provides direct register based access to closed loop tuning directives
- I²C slave digital Interface
- Used to interface other ams sensors with native support by the AS7225 (e.g. TSL4531 for adding Daylighting operation)
