Light-Emitting Diodes (LEDS): Implications for Safety

Health Physics, 2020
Abstract Since the original ICNIRP Statement was published in 2000, there have been significant improvements in the efficiency and radiance (i.e., optical radiation emission) of LEDs. The most important improvement is the development of ‘white’ LEDs that can be used as general lighting sources, which are more efficient than traditional ...
