Precautions for Using LED Screens in Thunderstorm-Prone Area

In summer, thunderstorms in summer and bad weather also test LED Screens. The electronic components in the LED display are highly integrated, and their sensitivity to interference is getting higher and higher. Thunder and lightning can harm the display in various ways. If hit, the lightning current will cause mechanical, electrical, and thermal damage to the place where the lightning current passes. It may even cause a fire. Therefore, the lightning protection of the LED screen is essential.

Lightning Protection Measures For LED Display:

1. For the protection of direct lightning strikes, install lightning rods on the support structure of the LED Screen (outdoor), indoor LED Displays or LED screens 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 displays, 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 Artificial grounding grid. The lightning protection device 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 arrester is determined according to the signal interface of the system. If it is a network cable, install a network signal arrester, and install a DB9 interface lightning arrester for the serial interface. The cross-sectional area of the ground wire cannot be less than 1.5mm square.

Regarding How To Use LED Display Reasonably Under Harsh Conditions, HONGHAI LED Gives You The Following Suggestions:

First of all：check the firmness of the hook regularly. If there is any looseness, pay attention to timely adjustment, re-reinforce or re-lift.

Secondly：when installing the LED Display, avoid looking directly at 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.
