Understanding issues affecting wireless LED display fire prevention technology

Wireless LED display security issue has been of concern to everyone, wireless LED display technology, the effective application of fire can also prevent some of the fire incident. Today we present a wireless led high bay lighting wholesale technology to analyze the fire look at the impact of wireless LED display technology elements of fire due mainly from those areas.
Wireless LED display can show changes in the numbers, text, graphics and video; not only the indoor environment can also be used for outdoor environment, with a projector, TV wall, LCD screen can not match advantage.


    First, the wireless LED display * analysis of fire prevention technology
The effect of large-screen LED technology major fire and the fire appeared screen raw materials, the process is closely associated with the box. Fireproof materials including wireless LED display and an external configuration within the material to analyze two aspects.


     1, wireless LED display inside the material analysis
1) In most display applications, the unit area of the display shows the greater, the greater its power consumption, the energization of the wire has a higher stability requirements. Numerous wire products, wire conforming national standard requirements to be able to ensure its security and stability, which requires three things: a conductive copper core for the carrier, the cross-sectional area of the core values of tolerance in the standard range, wrapped wire core rubber insulation and flame retardant to meet the standards, compared to the average copper clad aluminum core, core cross-sectional area is too small, not enough insulation rubber grade wire, power performance is more stable, less prone to short circuit;


        2) the best choice of products through UL certified power also chose the same product, the effective conversion rate to ensure power load security and stability in the external ambient temperature hot conditions, but also to work;


3) In terms of material external protective structures wireless LED display on the market higher fire rating of display products are mostly made of fireproof aluminum plate, excellent fire resistance, fire retardant is also very strong, the core material of special oxygen aging properties is also very strong, melting temperature 135 ℃, decomposition temperature ≥300 ℃, environmental performance, halogen, in line with SGS, flame retardant B-S1, d0, t0, refer to the use of standard UL94, GB / 8624-2006. aluminum plate general outdoor display products with high temperature, thermal shock and rain aging rapidly, so that in more humid climates season segment, rain screen is easy to penetrate the interior of electronic components led to a short circuit caused the fire;


4) There is also a significant part of the wireless LED display fireproof materials that plastic packages, plastic packages mainly use modular units Bottom mask material, the main use of raw materials is PC + glass fiber material with a fire-retardant features, not only has the resistance burning function better at high temperatures and in long-term use, no distortion, not brittle cracking, combined with better sealing glue to use, can effectively block the rainwater penetration into the interior of the external environment in order to cause a short circuit fire .


      2, the external configuration analysis wireless LED display
In addition to the internal analysis of the above materials will affect the fire effect, external configuration and design are also very important factors that influence fire wireless LED display technology, has summed up the external configuration:


1) external configuration and design for wireless LED large screen fire safety impact. External configuration mainly touched the fire problem in the heat, and it will work in the configuration screen appears exhaust fans and air conditioning to cool the heat shield inside the stop, the initiative to ensure the screen body temperature conditioning 8-10 per square assembly 1P insistence normal temperature, air conditioning or fan cooling configuration is not in place will form the disposal does not mean, susceptible due to raise the temperature inside the screen and cause security risks. Meanwhile, many LED companies in the box when you stop protection class test, simply mimic the external environment, water spray test, to be verified on a waterproof durability and strength, so the formation of the screen to show the product after use over a period of time there seepage situation attack, it is easy to attack a fire screen outdoor show or use the short life of the important reasons.


2) high quality equipment for wireless LED display products are as safe. Wireless LED large screen on fire by reason of ordinary consumer devices are improperly formed and substandard raw materials, such as local convergence is not strong, scattered, reverse polarity, the wire is not up to other materials failure, fire, and so the value is not enough . Thus after the end of the led high bay light manufacturers means necessary to stop the consumption and stringent inspection before use. Because LED large screen are electronic products, the main material of a partial belong combustibles, so basically started from "precautionary unburned" and the use of high-quality power supply, wire, IC, convergence devices such as flammable devices, reducing the rate of defects, and control LED large screen fire probability.


          In short, only a clear understanding of the impact of wireless LED display technology elements of fire, and the enterprises according to the relevant rules to be able to improve their performance, and prevent wireless LED display technology, which led to the issue of fire accidents, and thus enhance the entire LED industry in international competitiveness.
