Due to the popularity of the full -color LED display in indoor and outdoor display places, there are many fire accidents caused by product quality problems and design defects due to product quality problems and design defects in full -color. With the increasingly frequent safety accidents, we have just begun more in -depth analysis: how to prevent fire accidents in practice?
The full -color LED display has a hidden fire hazard. The key is that several main raw materials are still weak.
First, wire. In most display applications, the greater the display information of the unit area, the greater the power consumption, and the higher the standard for the stability of the wires. Among many wire products, only wires that meet national standards can ensure the safety and stability of wire products.
Second, power supply. UL -certified power products are also the best choice for products. Its reasonable conversion rate can ensure the safe and stability of the power load. Even if the external environmental temperature is high, everything can work normally.
Third, protective materials. Common outdoor display products are aging quickly under the impact of high temperature and rainwater. In the humid climate season, it is easy to penetrate into the screen by rain and dew, causing short circuits and fire accidents in electronic components. At the material level of the external safety protection structure of the display screen, most of the display screen products with higher fire -resistant levels on the market use fire -resistant and safe aluminum plastic plates, with excellent fire resistance and strong fire protection.
Fourth, plastic kit. The key to plastic kit is the application raw material for the bottom shell of the unit module. Key application raw materials are PC glass fiber raw materials with flame retardant functions. It not only has flame retardant, but also does not deform, not easy to become brittle and cracking under high and low and long -term application. Applying the glue with good sealing performance can reasonably prevent rainwater from penetrating into the interior, causing short circuit failure and fire.
In addition to internal raw materials that affect the actual effect of fire prevention, external design such as heat dissipation is also critical. The outdoor LED display continues to work at high temperature, and power consumption is also a great test. If it is a large area display, it will increase the difficulty of heat dissipation. In the past, large outdoor screens used electric fans to assist heat dissipation, and later developed into an internal air -conditioning equipment. At the same time, we cannot ignore the key factor in the final maintenance project. In other words, the fire prevention problem of full -color LED display should be paid attention to everywhere.
