Green Lighting Design of Underground Space from the Perspective of Health

It is well known that the lighting environment is crucial to human health, and the poor lighting environment is the main causation of visual fatigue, human body rhythm disorders, low work efficiency, which seriously affect people's work and life. Along with the rapid development of underground space in China, the lack of natural light, insufficient lighting level and uneven lighting distribution in the lighting environment of underground space are becoming more and more prominent. Existing research mainly focused on unidirectional studies such as natural lighting, healthy lighting, and energy efficiency in underground spaces, while only a few studies have been conducted on green lighting design from healthy perspective. To solve the existing problems, we analyze the introduction of natural light, simulation of daylight characteristics, simulation of natural landscape lighting, etc., put forward the improvement strategy of underground space lighting design, make suggestions on the future development direction of healthy lighting, with a view to providing a reference for the design of healthy light environment in underground space.
