[IEEE 2019 3rd International Conference on Circuits, System and Simulation (ICCSS) - Nanjing, China (2019.6.13-2019.6.15)] 2019 3rd International Conference on Circuits, System and Simulation (ICCSS) - Long-Term Effect of Visual Fatigue Caused by LEDs with Modulated Light

摘要： The visual fatigue caused by long-term work under steady light generated by fluorescent luminaires and fluctuated light generated by LED luminaires with different modulation depth was investigated through subjective reports of symptoms and physiological signals. Both the subjective feelings and the physiological results show that visual fatigue becomes more serious with increasing time under all the test lighting conditions. Compared to fluorescent luminaires, the LED luminaires with full-modulated light produced significantly severer symptoms. However, the LEDs with 75% modulation depth was fully accepted.
