What are the measures to reduce light pollution?

Avoid unnecessary and excessive light. The International Commission on Lighting has issued many documents on lighting standards, such as roads and various stadiums (football, tennis, swimming, ice sports, etc.). ) and advertisements. Use qualified lighting equipment. That is, use lighting equipment that can avoid or reduce light pollution. Lamps and lanterns should not shine in the sky, but should shine properly, only to illuminate the areas or objects that need illumination, so as to prevent places and objects that don't need illumination from passively receiving light, that is, to prevent overflow; Select the appropriate lighting mode and take necessary lighting control. This control includes space control and time control. For example, it is necessary to strictly limit the projection of strong projection lights and laser lights such as searchlights and narrow beam projection lights to the sky and people.

To reduce light pollution, generally speaking, the following points can be used for reference:

Strengthen urban planning management, rationally arrange light sources, strengthen the management of advertising lights and neon lights, prohibit the use of high-power and strong light sources, control the use of high-power civil laser devices, and restrict the use of materials with high reflection coefficient.

If the light is too strong, you can install blinds or double curtains in the room and adjust the light intensity accordingly; Or plant trees, flowers and grass around buildings to improve and adjust the lighting environment.

Few people in our country realize the harm of light pollution, so there is no unified standard in this respect. With the rapid development of urban night landscape construction in China, it is necessary to formulate technical standards for landscape lighting as soon as possible. It is suggested that the state formulate technical specifications and corresponding laws and regulations related to light pollution.

Most night lighting in China is not only energy-saving, but also very dazzling and easy to make people tired. It is suggested to promote the use of new energy-saving light sources.

It is suggested that ND filter or CPL filter be used to filter out light pollution during photography. It is suggested to use UHC filter to filter out urban light damage and sky glow when shooting stars.

Light pollution is a new environmental pollution source after waste gas, waste water, waste residue and noise pollution, which mainly includes white light pollution, artificial daytime pollution and colored light pollution. Light pollution is threatening people's health. In daily life, people's common light pollution is mostly caused by the reflection of mirror buildings, which causes dizziness of pedestrians and drivers, and discomfort caused by unreasonable lighting at night.

To reduce the harm of light pollution, a new urban pollution, it is imperative to strengthen urban planning management, rationally arrange light sources, strengthen the management of advertising lights and neon lights, prohibit the use of high-power and strong light sources, control the use of high-power civil laser devices, and restrict the use of materials with high reflection coefficient.

As ordinary people, on the one hand, don't stay in light pollution areas for a long time. If the light is too strong, you can install blinds or double curtains in the room and adjust them according to the light intensity. On the other hand, the whole people began to plant trees and flowers around buildings, and extensively planted turf to improve and adjust the lighting environment.

It is suggested that the state formulate technical specifications and corresponding laws and regulations related to light pollution. Few people in our country realize the harm of light pollution, so there is no unified standard in this respect. Experts believe that with the rapid development of urban night landscape construction in China, it is necessary to formulate technical standards for landscape lighting as soon as possible. Let's not take the detour that others have already taken. In addition, experts believe that it is also very important to strengthen the standardized management of night landscape design and construction.

At present, there are few professional technicians engaged in lighting design and construction in China, and many night landscapes that produce light pollution and light interference are caused by unscientific design and construction.

It is understood that Tianjin has promulgated the Technical Specification for Urban Night Lighting, which is the first technical specification for night lighting in China. There used to be an "Evaluation Standard for Urban Nightscape Lighting Engineering" for the nightscape construction in Beijing, but only simple items were used to measure light pollution. Experts call for the lack of scientific and normative urban night scene construction, which needs to be changed urgently.

Vigorously promote the use of new energy-saving light sources. At this stage, although most places will consciously use energy-saving light sources, most places still fail to consciously use energy-saving light sources for lighting.

Legal basis:

People's Republic of China (PRC) Environmental Protection Law

Article 4 Protecting the environment is the basic national policy of the country. The state adopts economic and technological policies and measures that are conducive to saving and recycling resources, protecting and improving the environment, and promoting harmony between man and nature, so as to coordinate economic and social development with environmental protection.
