  In the cold winter, the temperature becomes dry, so do a good job of fire prevention of the LED display in winter. The quality of the display fire protection technology is mainly related to the display fire protection raw materials and cabinet technology. Fireproof raw materials mainly include the wires and power supply used inside the display screen, the fireproof materials of the external protective structure and the plastic kits: 4 aspects:

  1. In most display applications, the larger the unit area of the display, the greater the power consumption, and the higher the requirements for the stability of the wire.

  2. UL-certified power products are also the best choice when choosing similar products. Their effective conversion rate can ensure the safety and stability of the power load, and can work normally in the hot external environment.

  3. In terms of materials for the external protective structure of the display screen, most of the display products with a higher fire rating on the market use fireproof aluminum-plastic panels, which have excellent fire resistance, strong fire and flame retardancy, and oxygen aging performance of special materials for core materials. It is also very strong, melting point temperature 135℃, decomposition temperature ≥300℃, environmental protection performance, low smoke and halogen free, etc. The aluminum-plastic panels of general outdoor display products age quickly with high temperature, rain, cold and heat impact, so that in the humid climate season, rain and dew will easily penetrate into the screen and cause short circuits in electronic components and cause fires.

  4. There is another important part of the fireproof raw materials for the display screen, which is the plastic kit. The plastic kit is mainly the material used for the bottom shell of the unit module mask. The main raw material used is the flame-retardant PC+glass fiber material, which not only has the flame-retardant function. , It can be used in high and low temperature and long-term use without deformation, brittleness and cracking. At the same time, it can be used in combination with a better sealing glue to effectively prevent rainwater from the external environment from penetrating into the interior and causing short-circuit and fire.

  Since LED electronic displays are electronic products, part of their main materials are also combustibles. Use high-quality power supplies, wires, ICs, connecting devices and other combustible devices to reduce the failure rate and control the LED display to catch fire Probability; technically, the LED display must be installed, instructed, and inspected by professionals during the installation process to prevent it from happening; the combustibles and combustibles around the LED display should be removed to prevent the surrounding fire hazards from causing the LED The display is on fire.
