With the development of LED display technology and continuous innovation, LED full color display in the stage performances and other places more and more widely, the role is more and more prominent. Today, large and small stage performances, it can be seen everywhere, has become part of our lives. With the people facing the safety, environmental awareness of the concept of continuous enhancement, the safety of the use of LED screen fire and other technologies also put forward higher requirements and standards.
In general, LED full color display fire prevention and control technology is mainly related to fire-resistant raw materials, box technology has a significant correlation, mobile performance companies in the procurement process must be firmly checked.
LED full color display Fireproof raw materials mainly include the use of the internal display of wire, power, external protective structure of fire protection materials and plastic sets of these four aspects:
First, in most of the LED full color display applications, the display screen body unit display the greater the unit, the greater the power consumption, the power stability of the wire also has a higher demand. Many wire products, the use of GB requirements in line with the requirements of the wire to ensure its safety and stability, and its requirements are three points: the core for the copper wire conductive carrier, core cross-sectional area tolerance in the standard range, wrapped wire core insulation And flame retardant to achieve the standard, compared to the general copper clad aluminum core, core cross-sectional area is too small, the insulation rubber grade is not enough wire, power performance is more stable, not prone to short circuit conditions.
Second, the choice of power, the best choice through UL certified products. Especially for the use of stage rental LED full color display, the effective conversion rate to ensure that the power load is safe and stable, in the external environment, hot conditions, but also work properly.
Third, the plastic package is mainly unit module mask shell material, the main use of raw materials is a flame retardant PC + fiberglass material, not only has a flame retardant function, more at high and low temperature and long-term use, no deformation , Will not brittle crack, combined with a good seal of the glue used to effectively block the external environment of the rain into the internal short-circuit caused by a fire, so you must use the LED full color display plastic package.
Fourth, in the LED full color display external protective structure of the material, the market high fire rating LED full color display products are mostly using fire-resistant aluminum-plastic plate, its excellent fire resistance, fire resistance is also strong, the core Material special material oxygen aging performance is also very strong, the melting point temperature of 135 ℃, decomposition temperature ≥ 300 ℃, environmental performance, low smoke zero halogen. Outdoor use of LED color screen display, especially in summer, hot weather, coupled with LED color screen display itself work, so it is easy due to high temperature caused by fire. Some of the Shenzhen LED display company uses a new security technology set, when the LED display temperature is too high, the screen will automatically cut off the power, so to prevent the occurrence of fire.
LED external display in addition to the internal raw materials will affect the fire effects, external configuration and design is also very important, but the external configuration is mainly related to the heat problem in the heat treatment, LED full color display at the same time will configure the exhaust fan and Air conditioning on the screen inside the cooling cooling is also very necessary.
