How to do the fire prevention work of the LED display?outdoor used led billboard Production

　　The key to the application of LED display fireproof technology is closely related to the LED display fire protection raw material and box technology. Fire -resistant raw materials include four layers: the wire and power supply used in the LED display, the fire prevention materials and plastic kits of the external safety protection structure;

　　1. In most LED display applications, the larger the display area of the unit area, the greater the power consumption, and the higher the requirements for the stability of the wire power. Among many wire products, only the application of wires that meet the requirements of national standards can ensure security and reliability. There are three regulations: the core is a copper -conductive carrier, and the cross -sectional tolerance of the wire core is within the standard range. The insulation and flame retardant of the wiring core rubber meet the standard specifications, which is different from the ordinary copper bag aluminum core. The wire core has a small cross -sectional area and insufficient wiring of insulating rubber levels. The charging performance is more stable, and it is not easy to cause short circuit;

　　2. Passage -certified power products are the best choices in the same industry. Its reasonable conversion rate can ensure the safe and stability of the power load, and can work normally in a hot external environment.

　　3. As for the materials of the external safety protection structure of the LED display, most of the display products with high fire resistance on the market are mostly fire -resistant aluminum -plastic boards, which have excellent fire resistance, fire safety and flame retardant. Strong oxygen aging performance, melting point temperature 135, decomposition temperature 300, environmental performance, UL94 halogen, conforming to SGS, flame retardant B-S1, D0, T0, and reference aluminum plastic plates that specify ordinary outdoor display products are high temperature on high temperature Under the impact of rainwater, aging is rapid. Under relatively humid climate conditions, rain and dew can easily penetrate the screen, causing short -circuit and fire accidents in electronic components.

　　4. The defense of LeD displayThere is a key part of fire raw materials. If the plastic kit, the plastic kit is mainly used as the raw material of the bottom shell of the unit module mask. The key application raw material is PC glass fiber raw materials with flame retardant effects. Deformation or crispy, easy to crack, can directly combine glue with good sealing performance to reasonably prevent rainwater from penetrating into the internal environment and cause short -circuit fire.

　　5. In the absence of breakthroughs in key raw materials such as lamp beads, increasing current does not increase brightness.

　　In addition, the internal raw materials will affect the actual effect of fire prevention. The external configuration is as critical as the design, but the key to external configuration includes heat dissipation in fire prevention. When the display is working, the exhaust fan and air conditioner will be configured to heat dissipation and heat dissipation inside the screen. It is recommended that the square flow line 1P every 8-10 air conditioners ensure that the temperature in the screen is kept at a normal constant temperature. If the air conditioner or exhaust fan is not configured properly, the heat dissipation distribution is uneven, and it is easy to cause the internal safety risk of the screen due to increased temperature. In addition, many LED display companies only simulate the testing of spray waterproof in environmental factors when testing the protection level of the box. The actual waterproof effect and strength of the actual waterproof effect need to be verified. As a result, the display product will have water seepage after a period of time. This is also the key reason why outdoor display is very easy to get angry or use short life. When dealing with thunderstorm temperature, the lightning arrester of the screen device is necessary. It is also a special tool for avoiding lightning strikes and burning the internal components of the screen. At the same time, it will cause lightning to enter the pavement, which is not easy to cause damage to the screen.

　　6. Correct installation

　　Because the full -color LED display should be an electronic component, some of the main raw materials are also flammable, so it is necessary to fundamentally "combustible" and apply combustible electronic components such as high -quality power, electric wires, ICs, and connection devices to reduce the failure rate Adjust the fire probability of the LED display; technically, in the entire process of installation of full -color LED display, professionals must do installation, guidance and inspection to prevent the suffering from the LED display.
