High-intensity LED lighting designs emit a large amount of blue light, which that appears white to the naked eye and create worse nighttime glare than conventional lighting. Streetlights with blue LED operate at a wavelength that most adversely suppresses melatonin during the night. It is estimated that white LED lamps have five times greater impact on circadian sleep rhythms than conventional street lamps. How can we eliminate the negative effect of “bad blue” in our design?
- Negative effect of Blue LED on human's health.
- What is “bad blue”? What is “good blue”?
- Why blue light is important? Why shouldn't we completely eliminate it in our product design?
- How to minimize the negative side of blue LED in exterior and interior design?
