#79 - The Sun is Blue

Aurelien David is the chief scientist for technology and R&D in LEDs and semiconductor optoelectronics at Soraa — a company founded by the inventor of the LED — and he was kind enough to appear on the Get a Grip on Lighting Podcast from the NAILD booth at Lightfair International.

The episode starts by addressing a recent report by ANSES about the hazards of blue light, particularly LEDs at night. Aurelien and Michael agree that the sky may be falling once again, given that so much of the light we experience, whether it be classic Edison incandescent bulbs or the sun itself project a great deal of blue light. Aurelien takes the time to explain the so-called Blue Peak; how it affects circadian lighting, how manufacturers are working to avoid it now, as well as the future of violet and cyan light as a dodge to the problems associated with blue. The episode closes out on the topic of lighting as the highest achievers in energy efficiency and waste savings, and its capacity to adapt to new technology will see it through the current health effect hurdles.
