Light in the city

With the rapid development of human economy, there are more and more skyscrapers in the city. The outer skin of these buildings is usually glass curtain wall, and the use of large-area glass will produce light pollution. Not only skyscrapers, but also some buildings will produce light pollution by turning on the lights because of their location and other reasons. At night, the light pollution is more serious because of the neon lights in the city. With the continuous development of society, light pollution is becoming more and more serious, and people pay more and more attention to it. More and more laws have been issued, hoping to improve and solve light pollution. A large number of data show us the harm of light pollution to human health. So my group are trying to use the refraction of light to solve the problem of light pollution in mega cities.We hope to change the reflection and refraction of light by designing the rotation of window glass, so as to reduce the light pollution caused by the reflection of external light during the day and the refraction of internal light at night.
