How to prevent led fire hazards

Large LED screens are widely used in various industries, with hundreds of thousands of areas. The shocking visual effect is very eye-catching, but there is also a crisis behind the scenery.The fire accidents caused by the fire of LED display screen occur almost every year. When the LED itself works, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit is very easy to be abnormal, thus causing a fire.

What aspects should be taken to prevent fire hazards from LED display?

1. The quality of LED display is excellent

（1） The safety and stability can only be ensured by using wires that meet the requirements of the national standard: the wire core is a copper wire conductive carrier, the cross-sectional area tolerance of the wire core is within the standard range, and the insulation and flame retardancy of the rubber wrapping the wire core meet the standard;

（2）Use high-quality power products that have passed UL certification, and its effective conversion rate ensures the safety and stability of power load;

（3） High quality protection technology and flame retardant materials shall be used to prevent rain, dew and dust from penetrating into the screen body and causing short circuit of electronic components and causing fire;

（4） The selected raw material is PC + glass fiber plastic kit with flame retardant function, which will not deform and become brittle and crack under high and low temperatures and long-term use;

（5）Select heat dissipation devices with good performance so as to release heat in time and avoid fire caused by high temperature.

2. Professional correct installation

Installation of large LED screen is also skilled, so be sure to find professionals to install it.There are hundreds or thousands of large screens, and the energy consumption is very high. Therefore, the LED large screen in Zhengzhou, Henan Province shall be equipped with exhaust fans and air conditioners to cool the inside of the screen.At the same time, lightning protection equipment shall be installed. In case of strong convection and lightning weather, the lightning protection pipe shall be timely inspected and tested. If it fails, it shall be replaced in time.

3. Daily maintenance awareness shall be strengthened

No matter how good a product is without daily maintenance, it will still have problems sooner or later. The LED large screen in Zhengzhou, Henan Province also needs maintenance at least twice a year.If damaged or other defective parts are found, they shall be replaced in time, especially the parts and small parts of the steel frame structure;When receiving the early warning of natural disasters such as bad weather, it is necessary to check the stability and safety of each component of the screen. If there is any problem, it should be handled in time to avoid unnecessary loss;Regularly maintain the surface coating of LED display screen and steel structure welding point to prevent corrosion, rust and falling off.It is summer with thunderstorms. When using the LED display screen, you must pay attention to selecting high-quality LEDs, finding professional personnel to install them, and paying attention to maintenance at ordinary times. Only in this way can the LED play its best role.
