There are many LED display manufacturers on the market today , there are large-scale screen enterprises, there are medium and high-end manufacturers, and there are also low-end wholesale manufacturers. Eliminating the hidden dangers of LED display has reached an urgent point. LED display for security risks we need to focus on the following points:
First, is the steel structure's force and steel selection reasonable ? The steel structure plays a vital role in the use of the LED display . It is the force point that supports the entire display. The steel structure is not strong and the design is unreasonable, which is easy to cause collapse.
Second, from the material of the box, the application of new materials can greatly reduce the weight and thickness of the LED display box. The light and thin cabinet is not only conducive to the installation and maintenance of the product, but also reduces the load and safety for the supported buildings and trusses. In addition, the perfect structural design can also avoid the appearance of LED display collapse accidents. The LED stage displays used for leasing are usually stacked very high, or hoisted high, with casters and spectators nearby, and structural safety is the most important part of the design process. Due to the short installation time, it is impossible to leave a long time to check whether it is firm, so it is especially important that the cabinet connection can be checked by the speed. Third, the design, manufacturing process is not fine LED display works at high temperatures, heat dissipation issues become the first problem to be solved. If the LED display area is too large, it will increase the difficulty of heat dissipation. If the heat dissipation design and manufacturing process are not refined, it will lead to safety hazards inside the screen due to temperature increase.
Fourth, the external cause LED display supplier did not systematically train the purchase customer, resulting in irregular operation. On the other hand, regular maintenance or post-maintenance is not timely and inconspicuous, resulting in the inability to detect and handle anomalies in time.
Fifth, the power supply selection of poor quality power supply is likely to cause fire and fire. Use inferior power supply or use the power rating of the power supply to a large extent, resulting in long-term overload operation of the power supply ( usually only 75% of the rated power of the power supply ) , and then the power cord terminal is inferior and the contact is not strong, these may be Become a cause of fire hazards.
Sixth, wire, flame retardant, inferior leakage and other products on the market, the quality of the wire is uneven, many wire spools are copper-clad aluminum, the appearance looks like copper wire, the actual is aluminum-copper wire ; this line is generally used for temporary use Lines cannot be used on regular products at all. There are copper problems of copper wire, problems of insulation layer, and the size of wire diameter ( generally required to be equipped with 1.2 times of the power of the display ) . If you neglect one of these problems, you will bury hidden dangers for later. In the event of a big disaster ; in addition, inferior wires are prone to electric leakage and cause electric shock. In most display applications, the larger the display per unit area of ​​the display, the greater the amount of electricity used, and the higher the stability of the wire. Among the many wire products, the use of wire that meets the requirements of the national standard can ensure its safety and stability.
In response to a few safety issues, an outdoor full-color LED display with a front-maintenance aluminum sump module and a die-cast aluminum housing was designed . In the outdoor, it is not only safe, waterproof, but also energy-saving. The product quality is stable, listed for one year, and it is highly recognized by the global outdoor LED display experts for its superior value . The products are not only sold well in China, but also exported to France, India, Netherlands, Russia, USA and so on.
