In summer, there are many thunderstorms and bad weather is also a test for the LED display. The LED display has a high degree of integration of electronic components, and its sensitivity to interference is becoming higher and higher. Thunder and lightning can harm the display in various ways, such as by being Hitting, where lightning current passes will cause mechanical, electrical, and thermal damage, resulting in serious damage to the LED display. It may even cause a fire. Therefore, the lightning protection of the LED display is essential. The following Sunrise team sorted out the lightning protection measures of the LED display for your reference. outdoor LED screens in summer

Lightning protection measures of LED display

1. For the protection against direct lightning, install a lightning rod on the support structure of the outdoor LED display. 2. For the protection of the steel structure, connect the structure to the LED display shell, do the same potential, and do the grounding. The grounding resistance generally requires less than 10 ohms. If the resistance does not meet the requirements, additional Artificial grounding grid. The lightning protector should also be grounded. 3. For the lightning current induced on the power line, install a single-phase or three-phase power surge protector on the power line. The cross-sectional area of the link line of the phase line should not be less than 10mm square, and the cross-sectional area of the connecting ground wire should not be less than 16mm square. 4. For the lightning current induced on the signal line, install a signal lightning protector on the signal line. The signal lightning arrester depends on the signal interface of the system. If it is a network cable, install the network signal lightning protector, and the serial interface install the DB9 interface lightning protector, etc. The cross-sectional area of the connecting ground wire should not be less than 1.5mm square.

Recommendations for using LED display in harsh conditions

1. Regularly check the firmness of the connection place. If there is any looseness, pay attention to timely adjustment, re-reinforcement or re-lifting. 2. According to the environment of the LED display, insect bites should be avoided, and rodenticide should be placed if necessary. 3. When installing the outdoor LED display, avoid looking directly at the ultraviolet rays and avoid direct sunlight for a long time. 4. The grounding socket must be installed correctly to avoid zero and live wire transfer errors. If the power is often cut off, please check the power supply carefully. The above is about how to do a good job of outdoor LED display lightning protection in summer. Regular daily inspection and maintenance of LEDs are also necessary. The editor reminds everyone that during the summer when lightning strikes frequently, please use LED displays reasonably to avoid screen problems affecting normal Work, the most important thing is to prevent fire.
