May 15, 2014…The US. Department of Energy has published a fact sheet that examines the effects of lighting on human health, with particular reference to LEDs. The DOE based the article entitled, Lighting for Health: LEDs in the New Age of Illumination, on a recent article by 14 leading researchers, which appeared in the journal Trends in Neurosciences.
The DOE report points out that inherently, LEDs are neither more hazardous nor more beneficial to human health than any other light source. However, their spectral power distribution can only be tuned to maximize human health and productivity if the guidelines for doing so are known. The lighting that is beneficial during the day may be harmful at night. This lighting’s effect might vary significantly between individuals.
The DOE says that presently, many details need to be considered about the physiological effects of LED lighting. So far, studies have found few definitive answers to important questions about the effect of light on different users. The DOE cautions against viewing any product as a panacea and any benefits depend on using the product properly. While non-visual needs are now being considered with LED lighting because of recent scientific advancement, the DOE says that much needs to be learned before widespread adoption of nonvisually-effective solutions is possible.
