In terms of the material of the outer protective structure of the display screen, most of the outdoor LED screens on the market are decorated with aluminum-plastic panels. In season, rainwater and dew easily penetrate into the interior of the screen, causing short circuit of electronic components and causing fire; LED screen module is fully sealed, electronic components and driver chips are sealed inside, the protection level is up to IP68, and military-grade immersion protects against rainwater, dust and corrosive gases It will not have any effect on electronic components and driver chips, and the box body is also made of die-cast aluminum, which is die-casted at one time. After the installation is completed, there is no need to decorate the aluminum composite panel. Fire rating up to B1.
The screen has a fire hazard, mainly because there are still some deficiencies in several major raw materials.
1. Wires.
In most LED electronic screen applications, the larger the unit area display of the LED electronic screen, the greater the power consumption, and the higher the requirements for the power supply 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.
2. Power supply.
UL-certified power supply products are also the choice to choose similar products. Their effective conversion rate can ensure the safety and stability of the power supply load, and can work normally even in the case of extremely hot ambient temperature.
3. Protect data.
Generally, the aluminum-plastic panels of outdoor LED electronic screen products age rapidly, high temperature, rain and cold, thermal shock, in the humid period, rain and dew can easily enter the interior of the LED screen, causing a short circuit. electronic components and cause a fire. Judging from the information on the external protection structure of the LED electronic screen, most of the LED electronic screen products with high fire rating on the market currently use fire-resistant aluminum-plastic panels, which have excellent fire performance and strong fire resistance. and flame retardancy.
4. Plastic kit.
The plastic kit is mainly the applied material of the bottom shell of the unit module mask. The main material used is PC glass fiber material with flame retardant function. It will become brittle and crack, and the use of glue with better sealing performance can effectively prevent rainwater from the external environment from seeping into the interior, causing short circuits and fires.
In addition to the internal raw materials that will affect the fire protection effect, external planning such as heat dissipation is also very important.
With the development of technology, our LED screens are becoming more and more popular. However, with the popularity of LED screens, there are more and more surprises, especially when some usage time has passed. Fire caused by long time or high temperature, so how should we do fire prevention work?
The quality of the display LED screen fire protection technology is mainly related to the display LED screen fireproof raw materials and box technology. Fire-resistant raw materials mainly include wires and power supplies used inside the display, fire-resistant materials and plastic kits for external protective structures
