In the process of approving large LED billboards, Shenzhen also has strict restrictions on the areas and road sections to be set up. مثلا, LED billboards should not be too close to residential areas and should generally maintain a distance of at least 20 meters from the opposite residential area. LED billboards should not affect traffic, should not face intersections directly, and large billboards should have their brightness lowered after 10 pm.
What is light pollution?
The brightness of sunlight is 2000CD (CD is the brightness parameter, called lumens), which exceeds twice the brightness of sunlight. When viewed directly, the human eye may feel uncomfortable. The international brightness standard for outdoor LED displays is 5000CD, and exceeding 5000CD is defined as light pollution.
It is reported that there is no unified legal standard for the brightness of outdoor LED display screens in China, but generally adjusting the brightness to 5500CD is the most suitable, and it is best not to exceed 6000CD.
1、 Adopting a brightness adjustment system that can be automatically adjusted by the system
The brightness of the environment varies greatly during the day and night, at different times and locations. If the playback brightness of the LED display screen is greater than 60% of the ambient brightness, we will clearly feel discomfort in the eyes, which means it causes light pollution to people. By using an outdoor brightness collection system, environmental brightness can be collected at any time. سیستم کنترل نمایش به طور خودکار با دریافت داده های سیستم ، روشنایی پخش مناسب برای محیط را از طریق نرم افزار تبدیل می کند.
2、 فناوری تصحیح خاکستری چند سطحی
سیستم نمایشگر معمولی از یک سلسله مراتب نمایشگر رنگ 8 بیتی استفاده می کند, که منجر به رنگهای سفت در برخی از مقیاس های کم خاکستری و رنگ می شود. همچنین می تواند با نور رنگی ناراحتی ایجاد کند. سیستم کنترل صفحه نمایش جدید LED A را اتخاذ می کند 14 سلسله مراتب نمایش رنگ بیت, سختی رنگها در انتقال را بسیار بهبود می بخشد. افراد را قادر می سازد هنگام تماشای رنگ های نرم احساس کنند. از ناراحتی مردم از نور خودداری کنید.
3、 انتخاب معقول محل نصب و برنامه ریزی معقول منطقه صفحه نمایش
یک برنامه تجربی برای مشاهده فاصله وجود دارد, زاویه دید, و منطقه نمایش, while image research has specific design requirements for display screen viewing distance and viewing angle. When designing display screens, efforts should be made to meet design requirements and plan reasonably.
4、 Selection and design of playback content
LED screens are public media, including public welfare, تبلیغات, and indicator categories. When selecting the content to be played, we must reach an agreement with the public’s requirements and avoid rejection psychology, which is also an important aspect of preventing screen light pollution.
It is important to solve the problem of light pollution in LED screens. While using technical means and policies and regulations to minimize light pollution, it is also necessary to coordinate the needs of advertisers and the viewing psychology of the public. آنها فقط با استفاده از صفحه های LED به روشی منطقی و علمی می توانند درخشش و رنگ را به شهر ما اضافه کنند!
