Abstract

The effects of visible light on our health and well-being are widely known and have led to the emergence of circadian-friendly or ‘human-centric’ lighting. The effects of far-red or near-infrared (NIR) light on our bodies are less known (in the lighting community). These effects, called ‘photobiomodulation’ are mostly employed in specialty or therapeutic devices for wound healing or pain relief. However, a double-blind and placebo-controlled clinical study now shows that photobiomodulation is not only a local effect: generally healthy people that are exposed to NIR light benefit from improved health and well-being. Unfortunately, indoors we are deprived of NIR light as LED-based lamps only emit in the visible spectrum, and most windows block all wavelengths beyond the visible. Consequently, there is a need for NIR light sources that provide people indoors with the right dose of NIR light in an energy-efficient way to improve their health and well-being.
