Four fire protection technologies of LED display
With the development and continuous innovation of LED display technology, LED full-color display has become more and more widely used in stage performances and other places, and its role has become more and more prominent. Nowadays, it can be seen everywhere on stage performances large and small, and it has become a part of our life. As people’s awareness of safety and environmental protection continues to increase, higher requirements and standards have also been put forward for the safe use of LED screens and other technologies.
Generally speaking, the quality of indoor ultra slim LED display fire protection technology is mainly related to fireproof raw materials and cabinet technology. Mobile performance companies must firmly check in the procurement process.
The fireproof raw materials of the LED full-color display mainly include four aspects: the wires used inside the display, the power supply, the fireproof material of the external protective structure and the plastic kit:
1. In most LED full-color display applications, the larger the unit area of the display screen, the greater the power consumption, and the higher the requirements for the power-on stability of the wire. Among many wire products, only the wire that meets the requirements of the national standard can ensure its safety and stability. There are three requirements: 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 of the rubber wrapping the wire core. Compared with the general copper-clad aluminum wire core, the cross-sectional area of the wire core is too small, and the insulation rubber grade is not enough, the energization performance is more stable, and the short circuit is not easy to occur.
2. When choosing a power supply, it is best to choose products that have passed UL certification. Especially for the full-color LED display used in the stage rental, its effective conversion rate can ensure the safety and stability of the power load, and it can work normally even when the external ambient temperature is hot.
3. The plastic kit is mainly the material used for the bottom shell of the unit module mask. The main raw material is PC+glass fiber material with flame retardant function. , It will not become brittle and crack, and at the same time, it can effectively prevent the rainwater from the external environment from penetrating into the interior and cause a short circuit and fire. Therefore, it is necessary to use the LED full-color display plastic kit.
4. In terms of the material of the external protective structure of the LED full-color display screen, most of the LED full-color display screen products with high fire rating on the market are made of fire-resistant aluminum-plastic panels, which have excellent fire resistance, fire resistance and flame retardancy. The oxygen aging performance of the special material is also very strong, the melting point temperature is 135 °C, the decomposition temperature is ≥300 °C, environmental protection performance, low smoke and no halogen. LED color screen display used outdoors, especially in summer, the weather is hot, and the LED color screen display itself is constantly working, so it is easy to cause fire due to excessive temperature. Some Shenzhen LED display companies have adopted new safety technology settings. When the temperature of the LED display is too high, the screen will automatically cut off the power supply, thus preventing the occurrence of fire.
In addition to the internal raw materials that will affect the fireproof effect of the led video wall, the external configuration and design are also very important, but the external configuration mainly involves the heat dissipation in the fire prevention problem. When the LED full-color display works, it will be equipped with exhaust fans and It is also necessary for the air conditioner to cool down the interior of the screen.
