With the increasingly mature technologies such as artificial intelligence, big data and Internet of things, smart cities have set off a new upsurge of urban construction.According to relevant data show that there are more than 600 domestic cities in promoting wisdom city construction, although now wisdom city construction in our country is still in its infancy stage, the future with wisdom, wisdom, communications, intelligence, wisdom, campus security, wisdom, will be the focus of the wisdom urban community areas, trillions of market potential for quick release.However, as the smart city project is in full swing, LED displays as smart city display terminals will also be seen everywhere, followed by more and more serious "light pollution" problem, how should the LED outdoor display enterprises deal with it?
The LED display industry has a long history of light pollution
With the continuous progress of industrialization, as early as the 1930s, the concept of light pollution was put forward by the international astronomical community.As a by-product of industrial civilization, the sources of light pollution include external and internal lighting of buildings, advertising, commercial real estate, factories, streetlights and stadium lighting.Outdoor LED display screen is widely used in outdoor advertising media in recent years, become the most eye-catching signs, designs city-lighting today along with the advancement of wisdom city, urban building lighting engineering, intelligent lighting project more and more, but because there is no clear standard definition, outdoor display screen brightness depending on the manufacturer or the user's own definition, so there is a misunderstanding of the light pollution, in fact use many outdoor display screen, outdoor lighting at night is inefficient, too bright, inappropriate goals, inappropriately covered, and in many cases, completely unnecessary.
In the LED display industry, it has always been a habit to use high-brightness LED light sources. "one bright light covers a hundred ugly", which can cover up many defects of the display screen when the brightness is very high.Excessive brightness is the direct cause of "light pollution". Light pollution mainly comes from two aspects.In order to meet the market demand, some display manufacturers unilaterally pursue high brightness. In addition, without the restriction of relevant industry standards, some enterprises blindly follow the trend. The brightness of some outdoor display screens produced by them exceeds the standard seriously, resulting in serious light pollution.Second, in the aspect of display screen use, many LED display users do not have a professional and comprehensive grasp of the performance of LED display, so there is a big difference between day and night in the playing time of LED display.During the day, high illumination also requires high brightness of the display screen, but at night, it does not need too bright, so it is not necessary to be so high brightness.Because there is no relevant standard specification, the owner also did not carry out corresponding debugging on the display screen, thus causing some light pollution.
Light pollution will be brought into the legal management of LED screen enterprises need to pay attention
In fact, as early as December 2014, "chengdu outdoor advertising set technical management regulations" has been formally implemented.According to the regulations, the latest time to shut down outdoor LED displays is 22:30.Later, the LED screen interference light evaluation requirements (GB/T 36101-2018) implemented on October 1, 2018 clearly stipulates the classification and evaluation requirements of LED screen interference light at night, and the first LED screen light pollution case in chongqing is also judged according to this regulation.At this year's two sessions, wen xiangcai, a member of the national committee of the Chinese people's political consultative conference (CPPCC) and a researcher at the China environmental monitoring station, proposed that the harm caused by light pollution should be paid attention to, and in particular included in the rule of law.
LED display industry in the outdoor LED display market, there is no certain standard, choose a light source with too high brightness, resulting in light pollution that people identify, but this light pollution can be prevented, LED display enterprises should also recognize this problem, choose the right light source.In the future, the problem of light pollution will eventually go through the legislative process, and LED outdoor display screen will urgently solve this problem.It should be said that in recent years, the local government urban construction departments to clean up and rectify the outdoor advertising market, has sounded the alarm for us.It's time for the LED display industry to face up to the problem.
LED outdoor display screen related enterprises should how to deal with
First, LED display companies need to change their minds.Before, there were no relevant laws and regulations to regulate light pollution in LED outdoor displays, and relevant enterprises didn't pay enough attention to light pollution.Now the issue of light pollution will enter into the legislative discussion level, LED outdoor display related enterprises should also start from the concept of attention, light pollution should also be included in the enterprise production and operation of important considerations.
Secondly, in the construction of smart city, reasonable design should be made for night lighting. Providing reasonable design for night lighting is the most fundamental way to control light pollution.The control of urban night scene lighting should adopt the method of intelligent centralized management and decentralized control.For example, the switch control of floodlight lighting can be used in peacetime mode, holiday mode, major holiday mode;For the switch control of advertisement, decoration, road lighting, etc., microcomputer timing switch or optical timing off mode can be adopted.
Finally, the light pollution should also be amended to strengthen the law, determine the subject of legal responsibility, the responsibility of administrative organs.Standards for the quality of light environment shall be formulated, which is the basic standard for the prevention and control of light pollution.At the same time, we will encourage social organizations that are qualified to issue community standards to participate in the formulation and release of relevant standards to effectively prevent and control light pollution.Future legislation on light pollution will also address issues related to outdoor LED displays.With the continuous improvement of legislation, enterprises related to LED outdoor display screen should gradually study and come up with more perfect solutions to light pollution.Enterprises related to LED outdoor display screen should actively seize the initiative before legislation, adapt to market demand, seize market development opportunities, change passivity into initiative, and win opportunities for enterprises.
LED industry is a "light" industry, and LED display brightness problems, inevitably become one of the "light pollution" manufacturers.Because there is no specification and industry standards, many outdoor LED display and outdoor lighting night show very dazzling brightness, cause serious light pollution on the surrounding environment, so as the LED display company, express in flight wisdom city construction, should pay attention to light pollution problems, the concept of awareness on the rise, and put into research and development, design, production process, to promote the improvement of the industry standards of governance, light pollution is related to the industry to resolve the problem, after all, the development of the ecological environment, to create a conducive to the development of the whole industry ecology which need LED display industry to the combined efforts of everyone,It is believed that only with the joint efforts of people in the LED display industry can we usher in a better ecological environment for the LED display industry.
