What issues should be paid attention to in the fireproof material of led display? What is the fire rating of your display? ...I often encounter such questions from customers. Regarding the fire protection function of the led display, the editor of Topsun Optoelectronics has something to say, please see below for details.

   The fireproof raw materials of the led display mainly include the wires used inside the led display, the power supply, the fireproof material of the external protective structure and the plastic kit.

1. In most LED display applications, the larger the unit area of the LED 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 core cross-sectional area tolerance 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 aluminum core, the core cross-sectional area is too small, and the insulation rubber grade is not enough, the energization performance is more stable, and the short circuit is not prone to occur.

2. UL-certified power supply products are also the best choice when choosing similar products. Their effective conversion rate can ensure the safety and stability of the power supply load, and can work normally in the case of high external ambient temperature.

3. In terms of the materials for the external protective structure of the LED display, 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 and flame retardancy. Conventional aluminum-plastic panels With the rapid aging of high temperature, rain, cold and heat, rain and dew will easily penetrate into the inside of the screen in relatively humid weather seasons, causing short circuits in electronic components and causing fires.

4. There is another important part of the fireproof raw materials for the led display screen, which is the plastic kit. The plastic kit is mainly the material used for the bottom shell of the unit module mask. The main raw material used is the flame-retardant PC+glass fiber material, which is not only flame-retardant. Function, it can be used in high and low temperature and long-term use without deformation, brittleness and cracking. At the same time, it can be used with glue with better sealing performance to effectively prevent rainwater from the external environment from penetrating into the interior and cause short-circuit and fire.

In addition to the internal raw materials that will affect the fire protection effect, the external configuration and design are also very important, but the external configuration mainly involves heat dissipation in the fire protection problem. When the LED display is working, an exhaust fan and air conditioner will be configured to cool the inside of the screen. It is recommended to install a 1P air conditioner every 8~10m2 to ensure that the temperature inside the screen maintains a normal constant temperature. Inadequate configuration of the air conditioner or exhaust fan will cause uneven heat dissipation, which may easily lead to hidden safety hazards inside the screen due to temperature rise.

    At the same time, when many LED display companies conduct the protection level test of the cabinet, they simply simulate the spray waterproof test of the external environment. The durability and strength of the waterproof effect need to be verified, so after the LED display product has been used for a period of time Water seepage occurs, which is an important reason why outdoor LED displays are prone to fire or have a short service life. When dealing with thunderstorms, the lightning arrester installed in the screen is an indispensable device to avoid strong lightning strikes and damage the internal components of the screen. The lightning arrester can directly lead the lightning to the ground without affecting the screen.

   The fireproof material is selected for the led display screen, which has a certain fire-proof function, but it only has the effect of flame-retardant. When it encounters a fire, it will not play a fire-proof effect. Therefore, when we use led display screens, we must put safety in the first place, and we must develop the habit of maintaining the screen frequently and stifle the danger in the bud.
