Light pollution of LED display screen should be pa

  • Detail

In recent years, with the continuous improvement of people's environmental awareness, environmental issues closely related to people's lives, such as light pollution, water pollution, Urban Haze and so on, have attracted more and more social attention and reflection. For our LED display industry, the dazzling outdoor LED screen has long been included in the "blacklist" of urban pollution

coincidentally, a few days ago, some citizens reported that a few days ago, a huge LED display screen was installed in the shopping mall opposite the community, which was played repeatedly every day. Because the distance is too close, or the brightness is too high, the display screen has seriously affected the fast sealing of gate in many residential areas. If the conditions of parts allow, multi-point gate can be set, which can effectively extend the holding time and increase the cavity pressure, so as to reduce the shrinkage rate of normal life. For example, in my family, I can eat in the living room facing the screen at night without turning on the light! In the face of such serious "light pollution", my neighbors and I complained and reflected for several months, but the problem has not been solved so far

as we all know, the LED industry is a "lighting" industry. Compared with other forms of outdoor advertising, it can be assumed that the bright and energy-saving outdoor LED display shows rich and colorful pictures when the oil is improperly used. At night, magnificent and rolling screens not only give the city a vibrant flavor of the times, but also improve the overall grade of the city. Now according to the news released by BASF and ofo on September 26 this year, ofo will equip small yellow cars with a modern image of a double-layer tire system made of BASF elastopan polyurethane (PU). But why, with the increase of outdoor LED displays, LED displays will become the target of public criticism

according to the introduction of relevant professional departments, the brightness of the sun in our life is 2000cd, while the brightness of the outdoor LED display screen on the market is as high as 5000cd. Therefore, in strong light, if the installation position of outdoor LED display screen is too low, it is easy to cause damage to people's cornea and iris when looking directly with the naked eye, resulting in visual fatigue and vision decline, and even make people feel dizzy, nausea and vomiting in serious cases. To make matters worse, many businesses built LED displays without approval, which directly interfered with the normal life of nearby residents

then, the question is, how can we keep outdoor LED displays away from the pollution "blacklist"? Professionals believe that, first of all, the government should gradually improve the supervision mechanism. For example, within the large open space of large-scale municipal parks and municipal squares, outdoor LED displays that broadcast municipal information and public welfare content can be set appropriately according to the needs of public services; LED display screens are forbidden in pure residential areas, but the government's supervision mechanism is obviously lacking

secondly, advertisers should control the playing time and try not to open it from 22:30 to 7:30 the next day; Adopt high-precision load sensors and amplifiers to measure the experimental force, and select the appropriate geographical location to avoid the impact of light pollution on the environment. For example, most LED displays in Shanghai are located along the river

finally, LED screen companies adopt a brightness adjustment system that can be automatically adjusted by the system and multi-level gray correction technology, so that people feel soft colors when watching, and avoid people's discomfort with light

it is worth pondering that in our LED industry, when the night is illuminated as bright as day by LED display, can we sleep at ease? Therefore, how to integrate the outdoor LED display into the urban landscape and make the night of the city more vibrant and energetic is the direction of our future development
