Fire prevention common sense of LED full color display screen

 

 

LED full color display screen, its structure includes external display, internal line, plastic kit, external protection and so on. Because of the complexity of its structure, there are still a lot of work to do in product fire protection. Here's a few small fire proofing knowledge of LED full color display, which I hope can help you.

First, wire quality: in the majority of LED display signs applications, the larger the unit area of the display screen, the greater the power consumption, the higher the demand for wire electrified stability. In many wire products, used to meet the standard requirements of the wire to ensure its safety and stability, which requires three points: copper wire core conductive wire core carrier, cross-sectional area of tolerance in the standard range of values, wrapped core rubber insulation and flame retardant reached the standard, compared to the general copper clad aluminum wire core and a wire core cross-sectional area is small, the level is not enough insulation rubber wire, electric performance is more stable, not prone to short circuit.

Two, power quality: UL certified power supply is the best choice to purchase LED full color display power. Its effective conversion rate can ensure the safety and stability of the power load, and it can also work normally in the hot environment of the external environment.

Three, full-color LED display exterior protection structural materials: market display products LED high fire rating is the fireproof aluminum plate, its excellent fire resistance, fire retardant is also very strong, the core material of the special material aging performance is also very strong, the melting point of 135 degrees Celsius temperature, decomposition temperature more than 300 DEG C, and low environmental performance smoke halogen-free flame retardant B-S1, with SGS, d0, T0, UL94, GB/8624-2006 standard reference. Generally, the aluminum-plastic panel of outdoor LED display is faster and faster with high temperature, rain, heat and cold impact, which makes it easy to penetrate into the screen body in the relatively humid season.

Four, plastic kit: the LED full color display screen plastic kit mainly is the unit module mask shell bottom shell material. The main raw material is PC+ glass fiber materials with flame retardant function, not only has the flame retardant function, more in high temperature and long time use, no deformation, no brittle cracking, combined with good sealing glue, can prevent the external environment effective rainwater penetration into the internal fire caused by short circuit.
