| Abstract |
Electrical safety, optical properties, and electromagnetic safety evaluation of LED applications are under way, but there is insufficient evaluation on the effect of radiance and irradiance on the human body. The visible region of the human eye is 400～700nm. In this study, we classify the LED luminaires in the 300～700nm blue light region as exemption group and risk group 1. Exemption groups have no effect on the human body, but when the risk rating is assessed as risk 1 or risk 2, the effects on the human body may be particularly dangerous because of the possible weakening or loss of vision and the rapid acceleration of age-related macular degeneration. The results of this study will be used to inform about the necessity of risk assessment of LED luminaires products that are about to be released to the market, and to create a system that can protect public health and public safety. |
