Artificial Sunlight Gets Boost from LED Windows

Constant exposure to artificial light might not be particularly healthy. Unlike sunlight, incandescent lamps and fluorescent tubes do not radiate the full spectrum of colors that humans need to keep their biological rhythm in sync with the Earth’s cycles of day and night.

The lighting industry is working to design systems that can follow humans’ natural sleep and wake cycle. Some of the major players are Circadian ZircLight, Philips, Trilux, and Versa Technology.

A new approach being taken by the lighting industry involves dynamic fixtures that look like real windows, skylights, and doors but that use LED technology. In 2019 Darras and his team invented  manufacturing method and form light fixture that combines window-construction principles with circadian-rhythm LED technology.
