ams announced the introduction of the new AS7220 Smart Lighting Manager. This product enables the realization of next-generation high-quality LED-based lamps and lighting products by utilizing closed-loop sensing to maintain more precise correlated color temperature (CCT) and light intensity while lowering system BOM costs.

The AS7220 is a successor product that combines a precision permanent calibration color sensor with an intelligent Cognitive Lighting engine for maintaining an independent closed-loop for the output of a white LED array. Consequently, it can automatically regulate phenomena such as color shift or LED brightness degradation caused by deviations in the LED driver due to aging, changes in operating temperature, and lifespan.

In the commercial, industrial, and high-end residential premium lighting system markets, manufacturers have been forced to rely on very tight LED binning to achieve the required CCT. Based on advanced sensor-driven algorithms, the ams AS7200 Smart Lighting Manager enables more extensive CCT testing and flexible binning by manufacturers, ensuring that LEDs provide stable and high-quality lighting.

Tom Griffiths, Senior Marketing Manager at ams, said, “The LED lighting industry continues to face the challenge of providing precisely identical color and output not only at operating temperatures but also throughout the lifespan customers expect.” While white LEDs perform well initially, differences in color or brightness develop over time. Furthermore, LEDs are evolving so rapidly that selecting the same LED for lighting less than a year old is no longer a cost-effective choice, which can lead to greater variations between lights.

Tom Griffiths, Senior Marketing Manager, continued, “Lighting manufacturers can relieve the burden of related technology and supply constraints by adding closed-loop sensing to their product architecture. Furthermore, they can reduce Bill of Materials (BoM) costs, expand the range of choices while maintaining consistency in component selection, and deliver more precise lighting quality throughout the product lifecycle.”
