What is the main cause of light pollution?

1, white light pollution:

When the sun shines strongly, the glass curtain wall, glazed tile wall, polished marble and various paints of buildings in the city reflect light, which is bright and dazzling.

2, mixed light:

Different kinds of light sources mixed together will seriously affect passive recipients. And it may lead to a car accident. What is even more frightening is that for pilots flying at night, it takes energy to find and identify aviation signal lights in these various lights.

3. Glare:

Light in the dark. Driving a high beam on a well-lit city street will temporarily "lose sight" of the opposite pedestrians or drivers, thus causing traffic accidents. And in the case of improper protection, this strong light will also hurt people's vision.

4, artificial sunlight:

After nightfall, advertising lights and neon lights in shopping malls and hotels are dazzling. Some intense light beams even go straight into the sky, making night like day, which is called artificial day.

Extended data:

Driving at night, being dazzled by the high beam of the opposite car when passing by; In the middle of the night, the lights of nearby buildings make the home look like daytime; On a sunny day, the strong light reflected by the glass curtain wall of the building makes people dizzy ... these are all light pollution in life.

In some local online political platforms, complaints and reports of light pollution are more prominent. At present, there is still a lot of work to be done to prevent and control light pollution, including refining relevant regulations and raising awareness.

"This store has set up three signboards, which are all on at night, making people unable to sleep." For more than a year, a resident of Baohe Sub-district Office in Chengdu, Sichuan Province has suffered from light pollution. After many complaints, urban management, street office and property management made efforts, which finally reduced the brightness of the lights and shortened the lighting time.

Glass curtain wall, neon lamp, high beam lamp, landscape lamp, etc. If used improperly, it may cause light pollution. Data show that excessive reflection of light from buildings or excessive illumination at night will not only affect people's sleep, vision and mood, but even disturb the living environment of animals and plants.
