With the continuous development of cities and the increase of urban buildings, light pollution has become a new type of environmental pollution source. It mainly includes white light pollution, artificial day pollution and color light pollution. Light pollution is threatening people’s health. In daily life, the common light pollution is mainly caused by the vertigo of pedestrians and drivers caused by the reflection of mirror buildings, and the discomfort caused by unreasonable lighting at night.According to different classification principles, light pollution can be divided into different types. Generally, light pollution is divided into three categories: white light pollution, artificial daylight pollution and color light pollution.When the sun shines strongly, urban buildings in the glass curtain wall, glazed brick walls, polished marble and various paint and other decoration reflected light, bright bright, dazzling. Some glass curtain walls are semicircular, reflecting light convergence is also prone to fire. Long time in the white pollution environment, the retina and iris will suffer varying degrees of damage, sharp decline in vision, cataract incidence as high as 45%. Still make the person dizzy upset, produce insomnia, appetite drops even, mood is low, the body is weak wait for the symptom of similar neurasthenia.In the night lighting of some big cities, the strong light is more, some strong light even straight into the clouds, so that the night is like the day, this phenomenon is called artificial day. The immediate cause of this phenomenon is that there is too much artificial light in cities. Artificial daylight affects people’s sleep at night, which affects their mental and physical health.Color light pollution is also caused by various artificial light sources (such as fluorescent lamps, neon lights, etc.) in the city. Color light sources are dazzling, not only bad for the eyes, but also interfere with the central nervous system of the brain, and can cause nausea, vomiting, insomnia and other symptoms. If people are under the irradiation of colored lights for a long time, they will also cause fatigue, dizziness, neurasthenia and other physical and mental diseases to varying degrees.Although light pollution can be seen everywhere in our life, the general public has little understanding and attention to light pollution, and even thinks that some light pollution phenomena are good. In fact, no matter what kind of light pollution is affecting our physical and mental health to a large extent. For example, in summer, the strong reflected light from the glass curtain wall enters the nearby residential buildings, increasing the indoor temperature and affecting normal life. We chose an empty space between the city’s high-rise buildings to create an amplifier for the phenomenon of light pollution. The harm of light pollution will be magnified in the form of maze, and people will lose themselves in the maze, just as the public does not realize the harm of light pollution. Finally, when the maze comes to an end, people will realize the harm of light pollution. We hope that through such an amplifier, the general public can have a preliminary understanding of the hazards of light pollution.
