This is a YouTube video titled "How to Fix Junk Light in LEDs: Robert Soler with Dave Asprey" containing a discussion from May 27, 2020, where DJ Sleepy and another speaker talk about the blue light spectrum in LEDs, focusing on removing harmful short-wavelength blue light and enhancing beneficial sky blue light to support circadian rhythms.
What did you do to fix the junk light problem in LEDs? Yeah. So there's kind of this blue light paradox, that there's some blue that's bad for us, the shorter wavelength blue, and there's the longer wavelength blue, like the sky blue. That's actually good for us. Yeah. What we did was we basically shifted it. We took out the bad blue and reappropriate into the good blue region, giving those sky blue signals that we need and getting rid of the bad blue in the shorter wavelengths. And it's just really kind of pinpointing that. And what we've done is we give this amplification of blue light. But it's really quite interesting because this photoreceptor, there's this key photoreceptor that drives our circadian rhythms inside the eye. The melanopsin sensor. You're talking about. Yes, yes, yes, yes.
