March 28 news, leading high-performance sensor solutions provider Amers Semiconductor, announced the AS7225 adjustable white light intelligent lighting system sensor, further expanding the sensor integrated adjustable white light lighting solution. The introduction of the AS7225 enables lighting OEMs to use Amers Semiconductor's closed-loop color temperature tuning and daylight compensation technology in their original microprocessor-based intelligent lighting designs. This will result in higher product accuracy, more flexible LED grading, and reduced system cost for adjustable white lighting. The AS7225 is equipped with the industry's first color sensor based on the International Commission on Illumination (CIE) 1931 color space XYZ tristimulus to make color perception more accurate. The CIE standard is recognized as the standard for human perception of color. Color temperature and daylight adjustment commands can be transmitted to the host microprocessor via a standard I2C interface, enabling IoT intelligent lighting manufacturers to effectively avoid costly calibration and algorithm development adjustments while reducing deployment time. Tom Griffiths, senior marketing manager at Amers Semiconductor, said: As the lighting industry continues to evolve in an adjustable direction, the closed-loop drive solution with integrated sensors not only increases the accuracy of white or daylight adjustment, but also reduces LED grading and system components. Requirements. This not only reduces overall material costs, but also saves time and costs in material management and manufacturing processes. The AS7225 is the latest addition to the Amers Semiconductor Sensing LightingTM Intelligent Lighting Manager family. The highly efficient AS7225 is available in a 4.5 x 4.7mm LGA package for flexible integration into lighting, light engines and a wider range of existing luminaire replacements, such as linear T-LED products. The device provides precise CCT regulation management for the warm and cool white LED strings that come with the fixture. In addition to CCT regulation, the AS7225 can also be used to detect light conditions outside the fixture to provide precise daylight management or to coordinate CCT and daylight-sensing blending with the Amers Semiconductor TSL4531 ambient light sensor. Tom Griffiths added that recent LED price trends indicate that LEDs will no longer be the most basic cost element in commercial lighting. This means that in a few years, adjustable lighting will become the standard for new commercial lighting. The improvement in comfort, productivity and health of superior lighting has been proven for a long time, and the cost of achieving superior lighting is gradually decreasing. Adjustable lighting will become a key factor in achieving a series of benefits through LED intelligent lighting platforms. Key features of the AS7225 include: Calibration for life based on CIE XYZ tristimulus color sensor Direct mapping of measured values ​​to CIE color space Register-based extensive instruction set for sensor control and precision control integrated with adjustable white, daylight or blending Support for the AS7225 spectrum-tunable IoT intelligent lighting manager is now in volume production.
