1. Wire quality: In most LED 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, 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 wire core has a small cross-sectional area, and the insulating rubber grade is not enough, the energization performance is more stable, and it is not easy to short-circuit.
2. Power supply quality: UL certified power supply products are the best choice for purchasing full-color LED display power supply. .
3. External protective structural material of full-color LED display: Most of the LED display 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, and oxygen aging of core materials. The performance is also very strong, the melting point temperature is 135 ℃, the decomposition temperature is ≥ 300 ℃, environmental protection performance, low smoke and halogen-free, in line with SGS flame retardant B-S1, d0, t0, reference standard UL94, GB/8624-2006. The aluminum composite panel of the general outdoor LED display screen ages rapidly with high temperature, rain and cold and thermal shock, so that in the relatively humid climate season, rain and dew easily penetrate into the interior of the screen, resulting in short circuit of electronic components and fire.
4. Plastic kit: The full-color LED display plastic kit is mainly the material used for the bottom shell of the unit module mask. The main raw material used is PC+glass fiber material with flame retardant function, which not only has flame retardant function, but also can not deform, become brittle and crack under high and low temperature and long-term use, and is used in combination with glue with good sealing performance. , which can effectively prevent the rainwater from the external environment from penetrating into the interior and cause a short circuit to cause a fire.
