Illumination Security of White LED in Visible Light Communication

Abstract

Medical experiments by white LED in visible light communication had been done to explain influence on visual function. The isolated RPE cells were cultured and light source illumination experiments with different illumination (lux), time and spectral range are designed. Using ELISA, the intracellular transcription factors in each group were detected, which include MCP-1 and IL-8. From experiments, the illumination safety threshold of white light is 500lux, and the illuminance safety threshold of blue light is 300lux. Compared with illumination (lux), Spectral range is the main factor of affecting visual function. In different spectral ranges, the magnitude of illumination and the duration of irradiation also affect visual function.
