Now, for many consumers who buy LED display products, they have certain considerations in terms of price, but not only in terms of price, but also in terms of quality. Of course, with the rapid development of modern technology, my country's LED display industry continues to grow at a high speed, the scale of the industry continues to expand, the technology continues to innovate, and the growth rate in the market continues to grow. LED display products have reached a new level in technology. However, there are still certain technological problems, such as the fire incident at the Hong Kong Yijunchuo Hotel on April 2, 2012. This is a typical failure in terms of process quality, and it also sounded a wake-up call for the entire LED display industry. Therefore, in order to develop in this high-tech industry, there must be shortcomings in the field of LED display safety application technology, and the standardization and standardization of LED products have been put on the agenda again. Especially pay attention to the fire safety application technology of led display.

The quality of the fire prevention technology of the led display is mainly related to the fire prevention raw materials and the box process of the led display. Experts pointed out that fireproof raw materials mainly include wires and power supplies used inside the display screen, fireproof materials for external protective structures and plastic kits:

1. In most LED display applications, the larger the unit area of ​​the LED display, the greater the power consumption, and the higher requirements for the stability of the wire.

2. In terms of materials for the external protective structure of the LED display, most of the display products with a higher fire rating on the market are made of fire-resistant aluminum-plastic panels, which have excellent fire resistance and strong fire and flame retardancy. The special core material is oxygen-aging The performance is also very strong, and the aluminum-plastic panels of general outdoor led display products age quickly with the impact of high temperature and rain, so that in relatively humid climate seasons, rain and dew can easily penetrate into the screen body and cause electronic components to be damaged. A short circuit causes a fire.

3. The UL-certified power supply is also the best choice when choosing similar products. Its effective conversion rate can ensure the safety and stability of the power supply load, and it can also work normally under hot external ambient temperature.

Fourth, there is another important part of the fireproof raw materials of the led display, that is, the plastic kit. The function is that it not only has the function of flame retardancy, but also can not be deformed, brittle and cracked under high and low temperature and long-term use. At the same time, it can be used with glue with good sealing performance, which can effectively prevent rainwater from the external environment from penetrating into the interior. This can cause a short circuit and cause a fire.

Of course, the appeal of the four points is mainly from the internal raw materials, but the external configuration and design are also very important. It mainly involves the heat dissipation in the fire protection problem. During the work of the LED display, an exhaust fan and an air conditioner will be configured to dissipate heat and cool down the inside of the screen. Sometimes the air conditioner or exhaust fan is not properly configured, which will cause uneven heat dissipation, which may easily lead to temperature rise. Potential safety hazard inside the screen. At the same time, many companies simply simulate the test of spraying and waterproofing in the external environment when testing the protection level of the cabinet. The durability and strength of the waterproof effect need to be verified. Water seepage will occur after the led products are used for a period of time. This is also an important reason for the fire or transparent video wall short service life of the outdoor led display.

To sum up, it shows that the LED display screen cannot be sloppy in terms of technology, and must be carefully and conscientiously to find problems, analyze problems, and finally solve problems. Process technology involves a wide range of aspects, so it is necessary to observe the reasons from many aspects. What we have mentioned above are all internal factors. Of course, human factors in the later maintenance process cannot be ignored. Therefore, if you want to be a leader in the LED display industry, you must firmly grasp the technology, demand yourself with high quality and strict specifications, and guide the healthy development of the industry, so as to enhance the international competitiveness of the entire industry and go international!
