According to the latest news from the Meteorological Department, this year’s No. 8 typhoon “Dianmu” (tropical storm level) is expected to land on the eastern coast of Leizhou Peninsula from the evening to the first midnight of the 18th. According to the “Emergency Plan for Flood Control, Drought, Wind, and Freeze Prevention in Guangdong Province”, the Provincial Defense Ministry decided to upgrade the emergency response of wind prevention level IV to level III at 9:00 on August 18.
In the south, the rainy weather gradually increased in May this year, and there were frequent typhoons, storms, and thunder and lightning. Compared with inland cities, southern coastal cities are economically developed areas in my country, and outdoor advertising screens account for two-thirds of the national advertising market share. Therefore, the safe use of outdoor advertising led display screens has been highly concerned by manufacturers, engineering units and users.
Considering that outdoor 55mm Flexible LED Mesh Screen display screens may be affected and damaged by typhoons, rainstorms, and lightning weather, LED screen brand manufacturer Liancheng issued a warm reminder that production-construction-use units must take measures to prevent or reduce damage to the display screen.
1. Anti-typhoon
There are many types of installation positions for outdoor led display screens, and the installation methods are also very diverse. There are wall type, mosaic type, column type, hanging type and so on. Then in the typhoon season. In order to keep the LED display equipment from falling, there are strict requirements on the load-bearing steel frame structure of the display. The engineering unit must design and install in strict accordance with the typhoon-resistant standard, and at the same time have a certain degree of earthquake resistance to ensure that the outdoor LED display will not fall and cause secondary hazards to personnel.
2. Anti-storm
There is a lot of rain in the south, so the LED display itself must have a high waterproof protection level so as not to be corroded by rain. In the outdoor use environment, the outdoor led display screen should reach IP65 level, the module should be packaged with glue, and the waterproof box should be selected, and the module and the box should be connected with a waterproof rubber ring.
3. Lightning protection
The impact of lightning on the display is fatal. If struck by lightning, the display will be seriously damaged. Therefore, the outdoor LED display must be equipped with lightning protection equipment such as lightning rods, grounded, installed a power surge protector in the distribution box, and then grounded to ensure the safety of the outdoor LED display.
4. Anti-high temperature
Outdoor LED displays generally have a large area, consume a lot of power during use, and emit a lot of heat. In addition to the high temperature outside, if the heat cannot be effectively dissipated quickly, it is likely to cause problems such as heating and short circuit of the circuit board. In production, ensure that the display circuit board is in good condition, and try to choose a transparent design when designing the shell to help heat dissipation. During installation, according to the installation situation, keep the environment where the display screen is in good ventilation, and add cooling equipment to the display screen if necessary, such as installing an external air conditioner or fan to help the display screen dissipate heat.
