LED full-color display, its structure includes external display, internal wiring, plastic kit, external protection, etc. Because of the complexity of its structure, there is still a lot of work to be done in terms of product fire protection. The following editor summarizes a few fire prevention knowledge of LED full-color display screens, and hopes to help you.  

 

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, 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 rubber covering the core is insulated. The performance and flame retardancy meet the standard. Compared with the general copper-clad aluminum core, the core cross-sectional area is too 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. Power quality: UL-certified power supply products are the best choice for purchasing LED full-color display power supplies. Its effective conversion rate can ensure the safety and stability of the power supply load, and it can work normally in the hot external environment. .

 

3. External protective structure materials for LED full-color display screens: Most of the LED display products with a higher fire rating on the market use fireproof aluminum-plastic panels, which have excellent fire resistance and strong fire resistance and flame retardancy. The special materials for core materials are oxidized. 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 retardancy B-S1, d0, t0, refer to the use standard UL94, GB/8624-2006. The aluminum-plastic panels of general outdoor LED display screens 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 body and cause short circuit of electronic components and cause fires.

 

4.Plastic kit: LED full-color 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 or become brittle and crack under high and low temperature and long-term use. At the same time, it can be used in combination with glue with better sealing performance. , It can effectively prevent rainwater from the external environment from penetrating into the interior and cause a short circuit to cause a fire.

 

The above are the four key points of fire prevention for LED full-color displays, hurry up and collect them!
