Every night comes, the first light of the Hua Deng, the various LED screen advertisements in the streets and lanes of Changchun City are particularly noticeable. With the jumping of the lights, various patterns appear from time to time. However, behind the bright and colorful LED screens, there are also problems that plague the lives of the citizens. The most prominent one is the LED display light pollution.
It is understood that the installation and playback contents of the LED display are subject to approval and supervision by the relevant departments, and there is no uniform standard in terms of brightness. This has become a “blind spot†for regulations. How big is the impact of LED screens on the public? How to supervise the "light pollution" of LED large screen? Recently, the reporter conducted an investigation and interview.
Installation of LED display does not require EIA
In the interview, the reporter also learned that at present, light pollution is generally divided into three categories in the world, namely, white light pollution, artificial daylight and color light pollution. At present, China has only relevant regulations on the glass curtain wall in Bailiang pollution, and there is no relevant regulation on artificial chalk and color light pollution. However, some experts have pointed out that in fact, the human eye is also very sensitive to color light. When the LED display uses different frequencies to play different advertisements, some advertisements may give people a glare, causing emotional and psychological discomfort. It belongs to light pollution. At present, China has not yet established a clear law and regulation on light pollution control. For this reason, there is still a lack of certain law enforcement basis for handling it. It is difficult to handle such complaints. The relevant staff of the Changchun Environmental Protection Bureau also said that the installation of LED displays in Changchun does not require environmental protection by the environmental protection department, but there is no relevant laws and regulations for light pollution in Jilin Province and Changchun City.
It is understood that there are no relevant laws and regulations in China to restrict this kind of "light pollution", and there is no definition standard like noise pollution. It is difficult to specifically deal with such complaints.
According to industry insiders engaged in LED manufacturing, the national standards for LED lights are in the pipeline, and the controversial LED light pollution problem will be effectively curbed. The person in charge pointed out: "The advantages of environmental protection and energy saving of LED lights have been uncontroversial, and the only thing that needs to be solved now is light pollution. Enterprises in the industry that cannot keep up with the strength and technology will be eliminated by the market with the introduction of the national standard. Nearly 30% of LED companies face this fate."
The source pointed out that the relevant national policies are only a legal means to stop the light pollution of LED displays, and the actual reduction of LED display light pollution requires the active cooperation of advertisers and users.
Standardize the size of LED display screens to develop brightness standards
In the interview, the reporter learned that the installation and playback contents of the LED screen are subject to approval and supervision by the relevant departments. There is no uniform standard in terms of brightness, which has become a “blind spotâ€. Relevant persons in the environmental protection department said that light pollution and noise pollution are different. The noise can be measured by decibels. The standard of light pollution is difficult to define.
Many citizens also said that not only the LED display screens in the bustling business district, but also many high-rise buildings in Changchun, where commercial and residential buildings are installed, all kinds of advertising neon lights are installed. The color of the lights is constantly changing at night, often one or two kilometers apart. It can be seen that it has a great impact on the residents. "I hope Changchun can make a brightness standard for these LED displays and advertising neon lights as much as possible, for example, can give the maximum brightness limit of the LED advertising screen, and distinguish the day and night standard." In the interview, many citizens suggested this.
In the interview, a lighting engineering technician also introduced that in fact, it is quite convenient to reduce the brightness of the LED screen. By setting parameters in the background software, the brightness of the LED screen can be lowered in one minute. At the same time, some people in the construction industry believe that relevant departments should strengthen the planning and management of outdoor electronic display settings, strict approval, reasonable distribution, and standardize the size of electronic display.
