Acuity Brands to license Circadian ZircLight’s IP

December 04, 2019 //By Julien Happich
Acuity Brands has entered into a strategic partnership with Circadian ZircLight whereby it will license the company’s intellectual property and commercialize the Zirc branded technology across North America.

Over the past five years, Circadian ZircLight has created evidence-based specifications for workplace lighting and developed specialized Zirc LED chips, light engines, control systems and luminaires to address the need for circadian lighting. This partnership reinforces both companies’ commitment to innovation that advances the value proposition of lighting designed to enhance human productivity, alertness and health.

“Circadian lighting supports the natural circadian rhythms of human beings,” said Rick Earlywine, Acuity Brands Lighting Senior Vice President, Architectural Lighting Solutions. “Our bodies are tuned to respond to the key circadian signal in natural light which is blue-rich during the day and depleted of blue after sunset. Yet, traditional lighting technologies, including LEDs, were developed to provide energy-efficient lighting with high enough light levels for humans to see well; circadian lighting considerations were not really in the mix. Circadian ZircLight is addressing this limitation by providing improvements through both patented LED technology and lighting controls to provide lighting that is more in tune with the blue-rich day and blue-depleted night signal of natural light.”
