The light emitting diode (LED) has wide applications recently. However, there are few literatures on the investigation for the influences of LED lighting on visual fatigue or its comparison with the fluorescent lighting. The aim of this study is to analyze the influences of different LED lighting conditions on visual fatigue, especially to discuss the impacts by the lighting condition factors of lighting type (LED or fluorescent lamp), illumination level, correlated color temperature (CCT). In this study, the subjective responses of visual fatigue and task performance were evaluated via a numerical verification experiment under LED and fluorescent lighting conditions, respectively. The experimental results indicate that illuminance, CCT and the type of light source indeed have effects on some symptoms of visual fatigue. Particularly, LED lighting can suppress visual fatigue more effectively than fluorescent one. Moreover, the task performance is not influenced by lighting conditions in these experimental setups.
