Light pollution will be included in legal management LED display companies need

With the maturity of technologies such as artificial intelligence, big data, and the Internet of Things, smart cities have set off a new wave of urban construction. According to relevant data, more than 600 cities in China are currently promoting the construction of smart cities. However, as smart city projects are in full swing, LED displays as smart city display terminals will also be seen everywhere, and with it is the increasingly serious "light pollution" problem. How should LED outdoor display related companies deal with it? ?

The problem of light pollution in the LED display industry has a long history

With the continuous advancement of the industrialization process, as early as the 1930s, the international astronomy community put forward the concept of light pollution, but light pollution has not been paid attention to until recent years. As a by-product of industrial civilization, light pollution sources include exterior and interior lighting of buildings, advertising, commercial real estate, factories, street lights, and stadium lighting. Outdoor LED displays have been widely used in outdoor advertising media in recent years and have become the most eye-catching signs of urban lighting. Nowadays, with the advancement of smart cities, there are more and more projects such as urban architectural lighting projects and smart lighting. Clear standards define that the brightness of outdoor display screens depends on the manufacturer or user's own definition, so there is a misunderstanding of light pollution. In fact, many outdoor display screens and outdoor lighting used at night are inefficient and too bright. Inappropriate targets, improperly masked, and in many cases completely unnecessary.

In the LED display industry, there has always been a habit of using high-brightness LED light sources. "One light conceals one hundred ugliness". When the brightness is high, many display defects can be covered. The excessively high brightness is the direct cause of "light pollution". Light pollution mainly comes from two aspects. First, it comes from the manufacturing link of the display screen. In order to cater to the market demand, some display manufacturers one-sided pursuit of high brightness, coupled with the absence of industry-related standards, some companies also blindly follow the trend. This phenomenon is not the case in the LED display industry. Second, in the use of the display screen, many LED display users do not have a professional and comprehensive grasp of the performance of the LED display. In the display time period of the LED display, there is a big difference between day and night. Of the difference. During the day, the brightness of the display is also high due to the high illuminance, but it does not need to be too bright at night, so such high brightness is not necessary. Because there is no relevant standard, the owner has not adjusted the display screen accordingly, which has caused a certain amount of light pollution.

Light pollution will be included in legal management, LED screen companies need urgent attention

In fact, as early as December 2014, the "Technical Management Regulations for Outdoor Advertising in Chengdu" was officially implemented. The "Regulations" make it clear that the latest closing time for outdoor LED displays is 22:30.

How should LED outdoor display related companies respond

First of all, LED display companies need to change their concepts. In the past, there were no relevant laws and regulations and corresponding standards for light pollution in LED outdoor display screens, and related companies also did not pay enough attention to light pollution. Now that the issue of light pollution will enter the legislative discussion level, LED outdoor display related companies should also begin to pay attention to it from a conceptual point of view, and also include light pollution as an important consideration for enterprise production and operation.

Secondly, in the construction of smart cities, a reasonable design should be made for night scene lighting. Providing a reasonable design for night scene 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 floodlighting can adopt normal mode, holiday mode, major festival mode; the switch control of advertising, decoration, road lighting, etc. can adopt microcomputer timing switch or light control timing off mode.

Finally, in response to light pollution, the law should be revised and strengthened, and the subject of legal responsibility and the responsibilities of administrative agencies should be determined. Formulate the "Light Environment Quality Standard", which is the basic standard for light pollution prevention and control. On this basis, relevant light pollution emission standards, monitoring method standards, etc. should be formulated. At the same time, we encourage social organizations qualified to issue standards for associations to participate in the formulation and promulgation of relevant standards to effectively promote light pollution prevention and control. The future legislation of light pollution will also involve issues related to LED outdoor displays. LED outdoor display related companies should gradually study and come up with more complete solutions to light pollution along with the continuous improvement of legislation. LED outdoor display related companies must actively seize the initiative before legislation is issued, adapt to market demand, seize market development opportunities, turn passive to active, and win opportunities for enterprises.

The LED industry is a “light-making” industry, and the brightness problem of LED display screens has inevitably become one of the “makers” of light pollution. Because there are no regulatory constraints and industry standards, many outdoor LED displays and outdoor lighting display very dazzling brightness at night, causing serious light pollution to the surrounding environment. As LED display companies, they should pay attention to light pollution when taking the smart city construction express train. , Pay attention to the concept and consciousness, and put it into the process of research and development, design, and production to jointly promote the improvement of industry governance standards. After all, the solution of light pollution issues is related to the development of the entire industry’s ecological environment. Ecological This requires the joint efforts of everyone in the LED display industry. I believe that only the people in the LED display industry can work hard together to usher in a better ecological environment for the LED display industry.
