Abstract：This article presents our recent studies on the effects of correlated color temperature and illumination on biological rhythm .Five male and five female were exposed to nine different LED lighting conditions (with illumination 300 lx, 500lx and 800 lx and correlated color temperature 2700K, 4500K and 6500K).The results show that under “Ev =500 lx, Tc =4500K” the study participates'learning efficiency and binocular vision accommodation were better and physiological parameters were more stable than other lighting scenarios in the experimental setting Tc and Ev range.In addition to that they preferred “Ev =500 lx, Tc =4500K” over other lighting scenarios.Comprehensive consideration, the average horizontal illumination level at desk is 500 lx with correlated color temperature 4500 K of LED lighting is a preferable lighting environment for learning and office working .
