The key to the application of fire prevention technology in ED display screens is closely related to the fire prevention raw materials and box technology of LED display screens. The fireproof raw materials include four layers: the wires and power supply used inside the LED display screen, the fireproof materials and plastic kits for the external safety protection structure;
1. In most LED display applications, the larger the unit area of the display, the higher the power consumption, and the higher the requirements for the stability of wire conduction. Among numerous wire products, only wires that meet national standards can ensure safety and reliability. There are three regulations: the wire core is a copper conductive carrier, the cross-sectional area tolerance of the wire core is within the standard range, and the insulation and flame retardancy of the rubber covering the wire core comply with the standard specifications, which is different from ordinary copper-clad aluminum wire cores. Wires with small core cross-sectional area and insufficient insulation rubber grade have more stable electrical performance and are less likely to cause short circuits;
2. UL certified power products are the best choice in the same industry, and their reasonable conversion rate can ensure the safety and stability of power loads, and can work normally in hot external environments.
3. As for the materials for the external safety protection structure of LED display screens, most of the display screen products with high fire resistance on the market are fireproof aluminum-plastic panels, which have excellent fire resistance, fire safety, and flame retardancy. The core material special material has strong oxygen aging performance, melting point temperature of 135, decomposition temperature of 300, environmental performance, UL94 halogen-free, in compliance with SGS, flame retardant B-S1, d0，t0， The aluminum-plastic panel of ordinary outdoor display products, as per the reference usage standards, ages rapidly under high temperature and rainwater impact. In relatively humid weather conditions, rainwater and dew can easily penetrate the screen, causing electronic component short circuits and fire accidents.
4. The fire-resistant raw materials for LED display screens have a key component. If we talk about plastic kits, they are mainly used as raw materials for the bottom shell of the unit module face mask. The key application raw material is PC glass fiber raw material with flame retardant effect. It not only has flame retardant effect, but also will not deform or become brittle under high and low temperature and long-term application, and is easy to crack. It can be directly combined with adhesive with good sealing performance to prevent rainwater from the external environment from seeping into the interior and causing short-circuit fires.
5. Without breakthroughs in key raw materials such as LED chips, increasing current does not improve brightness. If the air conditioning or exhaust fan is not properly configured and the heat dissipation distribution is uneven, it is easy to cause safety risks inside the screen due to temperature rise..
6. Correctly installed. Because full-color LED displays should be electronic components, and some of their main raw materials are also flammable, they need to be fundamentally “flame resistant” by using high-quality power supplies, wires ic、 Combustible electronic components such as connectors can reduce failure rates and adjust the fire probability of LED displays; Technically, professionals must provide proper installation, guidance, and inspection throughout the entire process of installing full-color LED displays in order to prevent potential issues before they arise.
