Thunder and lightning threaten outdoor LED full-color screens!

I don't need to say more about the power of thunder and lightning. I remember that I was most afraid of thunder in the sky when I was young. The outdoor full-color LED screen is also afraid of lightning.
The voltage of lightning is very high, reaching 100 million to 1 billion volts! It is 10,000 to 100,000 times that of our commonly used high-voltage lines. Under such a high voltage, the charged cloud layer breaks through the atmosphere to form a single release of electrical energy. When the lightning is released, the charge in the charged cloud layer decreases rapidly, causing the metal conductor about 2 kilometers around the lightning point to produce electrostatic induction and electromagnetic induction, forming high voltage or instantaneous current in the conductor. Both high voltage and instantaneous inrush current can cause the LED display power supply to burn out, the chip and the lamp tube are broken down, and the damage caused by lightning to the outdoor LED display is irreparable.
Outdoor full-color LED screen is very important for lightning protection. Next, let’s take a look at lightning protection measures for outdoor LED full-color screens:
1. Install lightning protection pins. It is best to install a well-grounded lightning rod 5 meters above the screen body near the screen body (lightning rods should not be installed on the screen body structure, which is not lightning protection but lightning, remember to remember) to prevent lightning from directly hitting the screen body.
2. Install lightning protection device. Install SPD surge arresters inside the display power distribution box to prevent the external main cable from being damaged by the induced current caused by lightning strikes.
It is beyond doubt that benefits led light engine module. Market sentiments are strong, especially in the light of growing led light engine observed globally.
Above all, we expect to be a credit to the communities we serve, a valuable resource to our customers, and a place where our dedicated About Us can grow and prosper.
The team of engineers and developers at Demo Photoelectric Technology (Wuxi) Co., Ltd. are the best in their own way and we promise to provide timely service to our esteemed clients.
