How to deal with light pollution scientifically

Measures to reduce light pollution include: 1. Avoid unnecessary and excessive light; 2. Use qualified lighting equipment, such as using lamps and lanterns that are appropriately bright, only illuminate the areas or objects that need to be illuminated, and prevent places that do not need to be illuminated and objects from receiving light passively; 3. Choose the appropriate lighting method and strictly control the time and space of lighting.

Light pollution, as an adverse effect caused by a certain number and specific direction of barrier light, destroys the normal living environment of the people around the pollution source, belongs to a new form of environmental pollution, and should be prevented. Article 65 of the Tort Liability Law of the People's Republic of China stipulates that: "Where damage is caused by environmental pollution, the polluter shall bear tort liability."

The National Committee for the Examination and Approval of Scientific and Technological Terminology has approved and published the definition of light pollution: 1. Excessive light radiation has an adverse effect on human life and production environment. This includes pollution from visible, infrared, and ultraviolet light.

2. One of the factors that affect the limit of the darkest object that an optical telescope can detect. It usually refers to the effect of atmospheric glow, zodiacal light, galactic background light, city night sky light, etc., which brighten the background of the starry sky over the observatory. The problem of light pollution was first raised by the international astronomical community in the thirties of the twentieth century, who believed that light pollution was caused by the negative impact of urban outdoor lighting on astronomical observations.

Later, countries such as Britain and the United States called it "interference light", and in Japan it was called "light pollution". It is now generally believed that light pollution generally refers to all kinds of light that affects the natural environment, adversely affects the normal life, work, rest and entertainment of human beings, impairs people's ability to observe objects, causes human discomfort and damages human health. Due to the adjustment of the pupil, the human eye can adapt to a certain range of light radiation, but when the light radiation increases to a certain amount, it will have adverse effects on human health, which is called "light pollution".

Optical radiation from a wavelength of 10 nanometers to 1 millimeter, i.e. ultraviolet, visible and infrared radiation, can be a source of light pollution under different conditions. Light pollution in a broad sense includes some things that may have adverse effects on people's visual environment and physical health, including the reflection of common books and papers in daily life, wall paint, and even the "light" of roadside color advertisements. In daily life, most of the common light pollution conditions are the dizziness of pedestrians and drivers caused by the reflection of mirrored buildings, and the discomfort caused by unreasonable lighting at night.

Light Pollution Solution 1) Improve the illumination of stationary light sources so that they can shine exactly where they are needed, rather than diffusing them around. 2) Improve the type of light source so that light waves are less likely to cause light pollution. 3) Re-evaluate the current lighting plan and redesign some or all of this type of plan so that only the places that really need it are illuminated, and the rest of the lighting is turned off as much as possible.

4) e.g. reduce sky glow, 5) reduce dazzling light, 6) reduce light nuisance and reduce clutter.

Solutions to light pollution 1 To ** increase the electricity bill (usually a company, or a building) 2 The billboard on the building should not be much more (the promotion of the shop) 3 Stipulate the electricity standard of the business 4 Publicize the benefits of saving electricity (especially from schools and kindergartens) 5 Emphasize that this is also a kind of environmental protection (* vigorously advertised on TV).

Light is necessary, you say it's polluting, I say it's repentance is insurance, just look at who is important.

The main causes of light pollution:

1. White light pollution:

When the sunlight shines strongly, the decoration of the glass curtain walls, glazed brick walls, polished marble and various paints of the buildings in the city reflects the light, and it is bright and dazzling.

2. Mixed light: Different kinds of light sources are mixed together, which will seriously affect the passive recipient. And it can lead to a car accident. What's even more terrifying is that pilots flying at night need to spend energy to find and identify aviation signal lights in these various lights.

3. Dizzy dismantling and arguing round light:

A bright light in the dark. Turning on the high beams on a well-lit city street can cause a temporary "loss of vision" to the suspect or driver on the opposite side, which can lead to traffic accidents. And, in the case of improper protection, this glare can also harm a person's eyesight.

4. Artificial daytime:

After nightfall, the advertising lights and neon lights on shopping malls and hotels flicker dazzlingly, making people dazzled. Some of the beams of light even reach into the sky, making the night look like day, the so-called artificial day.
