Blue Light Hazard and Risk Group Classification of 8 W LED Tubes, Replacing Fluorescent Tubes, through Optical Radiation Measurements

摘要: In this paper, the authors discuss results of a measurement survey artificial optical radiation emitted by 8 W LED tubes suitable for substitution 18 fluorescent lamps used general lighting. For both types lamps, three different color temperatures were chosen, 3000 K, 4000 and 6000 K. These measurements performed to evaluate photobiological safety sources. The radiance irradiance values have been measured in wide range wavelengths (180–3000 nm). obtained compared those similar lamps. analysis has focused on 300–700 nm, blue light range, which turned out be defining risk groups This classification is function maximum permissible exposure time as indicated European Standard EN 62471 lamp systems.
