LED display screens have been applied in many scenarios, and the scope is also expanding. It is often seen both indoors and outdoors. LED is an electrical product that generates a lot of heat during operation. Therefore, LED display screens need to be Screening to prevent fire hazards is the key. According to relevant statistics, in recent years, more and more fires have been caused and induced by LED reality. How to prevent fires caused by LED screen? At the same time, what problems do users need to pay attention to? Let's followEager LED to share with you Knowledge about it!
What aspects should be started to prevent fire hazards of LED screen ?
First, LED wire, power supply
In most display applications, the larger the unit area of the LED panel, the greater the power consumption, and the higher requirements for the stability of the wire. Among many wire products, the use of wires that meet the requirements of the national standard can ensure their safety and stability. There are three requirements: the wire core is a copper wire conductive carrier, the tolerance of the cross-sectional area of the wire core is within the standard range, and the insulation of the rubber covering the wire core Compared with the general copper-clad aluminum wire core, the cross-sectional area of the wire core is small, and the insulation rubber level is not enough, the electrical performance is more stable and the short circuit is not easy to occur.
UL-certified power supply products are also the best choice when choosing similar products. Their effective conversion rate can ensure the safety and stability of the power supply load, and they can also work normally under hot external ambient temperature conditions.
Second, LED screen protective materials, plastic kits
In terms of materials for the external protective structure of outdoor LED displays, most of the display products with higher fire ratings on the market are made of fire-resistant aluminum-plastic panels, which have excellent fire resistance, strong fire resistance and flame retardancy, and the oxygen aging performance of special core materials It is also very strong, with a melting point of 135°C, a decomposition temperature of ≥300°C, environmental performance, low smoke and no halogen, conforming to SGS, flame retardancy B-S1, d0, t0, and reference standards UL94, GB/8624-2006. The aluminum-plastic panels of general outdoor display products age quickly with the impact of high temperature and rain, so that in relatively humid climate seasons, rain and dew can easily penetrate into the screen body, causing short circuits of electronic components and causing fires.
The plastic kit is mainly the material used for the bottom shell of the unit module mask. The main material used is PC fiberglass material with flame retardant function. It will become brittle and crack, and at the same time, combined with the glue with good sealing performance, it can effectively prevent the rainwater from the external environment from penetrating into the interior and cause short circuit and fire.
Third, professionals should install correctly
There are also skills in installing LED large screens, so be sure to find a professional to install them.
Large screens with hundreds or even thousands at every turn consume very high energy consumption. Therefore, exhaust fans and air conditioners should be equipped with large LED screens during installation to cool down the inside of the screen. At the same time, it is necessary to install lightning protection equipment, check in time during strong convection and lightning weather, test the anti-pipe, and replace it in time if it fails.
Fourth, the awareness of daily maintenance should be strengthened
No matter how good a product is without daily maintenance, it will go wrong sooner or later, and it needs maintenance at least twice a year.
If any defective parts such as damage are found, they should be replaced in time, especially the small parts of the steel frame structure; when receiving early warnings of natural disasters such as weather deterioration, it is necessary to check the stability and safety of each component of the screen. if there is a problem, deal with it in time to avoid unnecessary losses
Regularly maintain the surface coating of the LED display and steel structure welding points to prevent corrosion, rust and peeling off.
When using LED displays, we must pay attention to choosing high-quality LEDs, finding professionals to install them, and paying attention to maintenance at ordinary times, so that the LEDs can play their best effects.
