Dalam proses menyetujui papan iklan LED besar, Shenzhen also has strict restrictions on the areas and road sections to be set up. Sebagai contoh, 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. Sistem kontrol tampilan secara otomatis mengonversi kecerahan siaran yang cocok untuk lingkungan melalui perangkat lunak dengan menerima data sistem.
2、 Teknologi Koreksi Greyscale Multi Level
Sistem tampilan biasa menggunakan hierarki tampilan warna 8-bit, yang menghasilkan warna kaku dalam beberapa skala abu -abu dan transisi warna. Itu juga dapat menyebabkan ketidaknyamanan dengan cahaya berwarna. Sistem kontrol layar LED baru mengadopsi a 14 hierarki tampilan warna bit, sangat meningkatkan kekerasan warna dalam transisi. Memungkinkan orang merasakan warna lembut saat menonton. Hindari ketidaknyamanan orang dengan cahaya.
3、 Pilihan lokasi pemasangan yang wajar dan perencanaan area layar tampilan yang wajar
Ada rencana empiris untuk melihat jarak, sudut pandang, dan area tampilan, 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, periklanan, 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. Hanya dengan menggunakan layar LED dengan cara yang masuk akal dan ilmiah mereka dapat menambahkan kilau dan warna ke kota kami!
