With the rapid development of urban construction, the lighting projects in various places are surging, and “making the city bright†has become a fashion pursuit and ideal goal. Now, when night falls, not only the night scenes of major cities in the country are dazzling and radiant, but also in an ordinary small county town, it is also brilliant and eccentric. However, under the appearance of this "fire tree, silver flower, never sleeps in the city", a kind of noise pollution is spreading around us and should be highly vigilant.
Light pollution is the fifth kind of environmental pollution in addition to water pollution, air pollution, noise pollution and solid waste pollution. This pollution source will become another environmental killer that directly affects human health. Various unreasonable nighttime landscapes, outdoor flashing neon lights, decorative lights, advertising lights and colored light sources for entertainment venues, glass curtain walls, glazed tiles, polished marble and various decorative materials may all be for us. Physical health and the surrounding environment cause various adverse effects. Household lights, televisions, computers, etc. are also sources of pollution caused by light pollution. In particular, the night light with strong beam and long delay has a negative impact on the human body. Long-term exposure to a colorful glare environment can make people nervous, depressed, dizzy, and tired. Artificial white cockroaches can seriously disturb the normal body clock of the human body, making it difficult to fall asleep. Light pollution can cause visual fatigue and decreased vision. Inappropriate lighting settings can also jeopardize traffic safety and increase the incidence of accidents. Night glare can also harm birds and insects, which is not conducive to the ecological balance of nature. More seriously, the excessive lighting of the city is a huge waste of power resources, does not meet the industrial policy of energy conservation and emission reduction, and is not compatible with the concept of scientific development and harmonious development.
Increasingly serious light pollution has brought many harms to people, but it is worrying that this kind of harm has not caused enough attention until now. The reason is that people lack awareness of the potential of their harm. To this end, the following recommendations are made to prevent and control light pollution:
First, formulate laws, regulations and policies for the prevention and control of light pollution as soon as possible, and increase the content of prevention and control of light pollution in environmental protection regulations; clarify that urban construction is designed in strict accordance with scientific lighting standards, and eliminate light pollution from the source. Resolutely oppose the slick image project, prevent blind comparison, reasonably choose the light source, lamps and lighting schemes, eliminate excessive lighting, and strictly limit the generation of light pollution.
Second, actively promote the use of new technologies that are harmless, gradually eliminate backward production capacity, improve grades, reduce consumption, and achieve environmental protection and energy conservation. It is necessary to control and scientifically manage all kinds of landscape lighting, billboards and neon lights based on the coordination and unification of the ecological environment. Around the buildings and entertainment venues, more green planes should be set up, efforts should be made to improve the light environment, and attention should be paid to reducing high-power and strong light sources, and strive to make the city look harmonious and natural.
Third, strengthen management with the concept of energy conservation, and improve lighting with comprehensive management. The use of comprehensive management methods, coordinated use of various remediation methods. For cities with light pollution, the lighting power restriction policy is implemented. For cities with prominent light pollution and serious waste of resources, the necessary punishments and punishments shall be carried out, and economic, technical, legal, educational, and administrative aspects shall be taken to effectively rectify light pollution sources.
