What are the solutions to LED display screens facing the threat of lightning?

Needless to say, the power of thunder and lightning. I remember when I was a child, many people were afraid of thunder in the sky, and outdoor LED displays are also afraid of thunder and lightning. The voltage of lightning is very high,cog led reaching 100 million to 1 billion volts! It is 10,000 to 100,000 times that of our commonly used high-voltage lines. At such a high voltage, charged clouds break down into the atmosphere to release a primary electrical energy.

When lightning is released, the charge carried by the charged cloud layer decreases rapidly, causing electrostatic induction and electromagnetic induction in metal conductors about 2 kilometers around the lightning point, forming high voltage or instantaneous surge current inside the conductor.outdoor lcd digital signage High voltage and instantaneous surge current can cause the LED display power supply to burn out, and the chip and lamp tube to be broken down. The damage caused by lightning to the outdoor LED display is irreparable.

Therefore, it is very important to provide lightning protection for outdoor LED displays. So next,ips vs ads panel let’s take a look at the lightning protection measures for outdoor LED displays:

It is best to install lightning protection rods. It is best to install a well-grounded lightning rod 5 meters above the screen near the screen (lightning rods should not be installed on the screen structure, as they are not lightning protection but lightning guides, so remember) to prevent lightning from directly hitting the screen.

You can also choose to install a lightning protector. Install an SPD surge arrester inside the display distribution box to prevent induced current caused by lightning strikes on the external main cable from damaging the display.
