With the rapid development of modern technology, the application of LED display rentals has become more and more extensive. Commercial performances, new product promotion fairs, cultural performances and other LED displays frequently appear. In order to ensure the smooth progress of the performance, the standardization and standardization of LED products have been put on the agenda again. Especially LED display fire safety application technology is the focus. Mobile performance LED display companies must pay attention to the following issues in the performance of the project.
The quality of LED display fire protection technology is mainly related to the display fire protection raw materials and cabinet technology. Mobile performance companies must work hard to check during the procurement process.

Fireproof raw materials mainly include the wires and power used inside the display screen, the fireproof materials for the external protective structure and the plastic kits:
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. 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 core is a copper wire conductive carrier, the cross-sectional area tolerance of the core is within the standard range, and the insulation of the rubber covering the core And the flame retardancy reaches the standard, compared with the general copper clad aluminum core, the core cross-sectional area is small, and the insulation rubber grade is not enough, the electrical performance is more stable, and the short circuit is not prone to occur.
2. UL-certified power supply products are also the best choice when choosing similar products. Its effective conversion rate can ensure the safety and stability of the power load, and it can work normally even in the hot external environment.
3. In terms of the materials for the external protective structure of the LED display, most of the display products with a higher fire rating on the market are made of fire-resistant aluminum-plastic panels, which have excellent fire resistance, strong fire and flame retardancy, and oxygen aging of special materials for core materials. The performance is also very strong, the melting point temperature is 135 degree , the decomposition temperature is Greater than or equal to 300 degree , environmental protection performance, low smoke and halogen free, in line with SGS, flame retardant B-S1, d0, t0, refer to the use standard UL94, GB/8624-2006. The aluminum-plastic panels of general outdoor display products age quickly with high temperature, rain, cold and heat impact, so that in relatively humid weather seasons, rain and dew will easily penetrate into the screen and cause short circuits in electronic components and cause fires.
Fourth, there is another important part of the fireproof raw materials for LED display screens, that 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 plus glass fiber material, which is not only flame-retardant. It is more capable of not deforming or becoming brittle and cracked under high and low temperature and long-term use. 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 a short circuit to cause a fire.

In addition to the internal raw materials that will affect the fire protection effect, the external configuration and design are also very important, but the external configuration mainly involves heat dissipation in the fire protection problem. When the LED display is working, an exhaust fan and air conditioner will be configured to cool the interior of the screen. , It is recommended to install a 1P air conditioner every 8-10 square meters to ensure that the temperature in the screen body is maintained at a normal constant temperature. Inadequate configuration of the air conditioner or exhaust fan will cause uneven heat dissipation, which may easily lead to hidden safety hazards inside the screen due to temperature rise. At the same time, when many LED display rental companies conduct the protection level test of the cabinet, they simply simulate the spray waterproof test in the external environment. The durability and strength of the waterproof effect need to be verified, so the display products have been used for a period of time. After that, water seepage occurs, which is an important reason why outdoor displays are prone to fire or have a short service life. When dealing with thunderstorms, the lightning arrester on the screen is also an indispensable tool to prevent the internal components of the screen from being damaged by lightning. It can directly lead the lightning to the ground without affecting the screen.
