Bad weather is also a test for the LED display. The electronic components in the LED display are highly integrated, and their sensitivity to interference is getting higher and higher. Lightning can harm the display in various ways, such as being hit, lightning current Passing by will cause mechanical, electrical, and thermal damage, causing serious damage to the LED display. It may even cause a fire. Therefore, the lightning protection of the LED display is essential.
Outdoor LED display
Lightning protection measures for LED display:
1. For the protection of direct lightning strikes, install lightning rods on the support structure of the LED display (outdoor), indoor LED displays or LED displays with tall buildings next to them, you do not need to consider installing lightning rods.
2. For the counterattack of the steel structure, connect the rigid structure to the shell of the LED display, make equipotential and ground it, the grounding resistance is generally required to be less than 10 ohms, if the resistance does not meet the requirements, additional The artificial grounding grid. The lightning arrester should also be well grounded.
3. For the lightning current induced on the signal line, install a signal lightning protection device on the signal line. The signal lightning arrester is determined according to the signal interface of the system. If it is a network cable, install a network signal lightning protection device, and install a DB9 interface lightning protection device for the serial interface. The cross-sectional area of the ground wire cannot be less than 1.5mm square.
As for how to use LED displays reasonably under harsh conditions, the editor gives you the following suggestions:
First of all, check the firmness of the joints regularly. If there is any looseness, pay attention to timely adjustments, re-reinforcement or re-lifting.
Secondly, when installing the LED display, avoid looking directly at the ultraviolet rays and avoid direct sunlight for a long time.
Finally, the grounded socket must be installed correctly to avoid errors in the zero and live wire transfer. If there are frequent power failures, please check the power supply carefully.
