Outdoor LED display, as the new favorite of outdoor display advertising media in the future, is widely used in sports, advertising, transportation, education system and other public places. It is used for media display, information release, traffic guidance, creative display, etc.
French outdoor LED display screen has a high probability of becoming a lightning target. Once the LED display screen is struck by lightning, because it is a high-density integrated display, it is highly sensitive to anti-interference. The damage of lightning to it will cause mechanical, electrical and thermal damage, even fire. Therefore, lightning protection measures for LED are essential. So, how can South Africa's outdoor LED display screen prevent lightning strikes? How much is the outdoor led display in dubai?
Due to the high integration of electronic components in LED display screen, its anti-interference sensitivity is also getting higher and higher. Lightning can harm the display screen in various ways. If struck by lightning, the place where the lightning current passes will cause mechanical, electrical and thermal damage, which will lead to serious damage to the LED display, and even cause short circuit or fire.
Therefore, outdoor LED displays in South Africa should not only take protective measures, but also take lightning protection measures.
Generally, when installing French LED outdoor displays, LED display manufacturers should install lightning rods on the supporting structure, while LED indoor displays or LED displays with tall buildings nearby can consider not installing lightning rods. In addition, the steel structure itself can also cause lightning attacks. Therefore, equipotential measures should be taken at the connection between the steel structure and the LED display screen shell, and grounding measures should be taken. The grounding resistance value should generally be less than 10 ohms. If the resistance value cannot meet the requirements, an artificial grounding grid should be added, and the lightning arrester should also be grounded.
In addition to the screen and steel structure, lightning current will also be induced on the power supply, and single-phase or three-phase power lightning arrester will be installed on the power line. The sectional area of the link line of the phase line shall not be less than 10 mm2, and the sectional area of the connecting ground wire shall not be less than 16 mm2. The signal line shall also be equipped with signal lightning arrester, which shall be determined according to the signal interface of the system. If it is a network line, it shall be installed with network signal lightning arrester, and the serial interface shall be installed with DB9 interface lightning arrester. The sectional area of connecting ground wire shall not be less than 1.5mm2.
After installing the arrester, the screen shall be tested. At the same time, it is necessary to regularly check the firmness of the coupling. If there is any looseness, pay attention to timely adjustment, re reinforcement or re hoisting. When installing the LED display screen, avoid direct viewing of ultraviolet light and long-term direct sunlight. The grounding socket must be correctly installed to avoid wrong handover of zero and live wires. If the power supply is frequently cut off, please carefully check the power supply. According to the environment of LED display screen, insect bites should be avoided and rodenticide should be placed if necessary.

In a word, the South African outdoor LED display itself has the functions of waterproof, dust-proof and moisture-proof, and it should be exposed to the wind, sun and rain for a long time, especially in the thunderstorm season. If lightning protection measures are not taken, the screen may be hit by lightning, which may lead to the screen being struck by lightning. So? How to take lightning protection measures for outdoor LED display? Lightning rod and lightning arrester can be installed on LED display screen to avoid being hit by lightning.
