According to related reports, led display has occupied the dominance of outdoor advertising. At the same time, LED display fire accidents are endless, posing a great threat to our lives and property. Let’s take a look at the causes of frequent LED fire accidents.
1, Power supply. UL-certified power supplies are also the best choice when choosing the same type of product. The effective conversion rate ensures the safety and stability of the power supply load, even in hot external environments.
2, Wire. In most display applications, the larger the display per unit area of the display, the greater the power used and the higher the stability of the line. In many wire products, the use of wire in accordance with national standards ensures safety and stability. Inferior wires, hidden fires.
3, Plastic kit. The plastic kit is mainly used for the bottom cover of the unit module mask. The main raw material is PC fiberglass material with flame retardant function. It not only has a flame retardant function, but also does not deform under high and low temperature and long-term use. It will not become fragile and broken. At the same time, it can be combined with glue and has good sealing performance, which can effectively prevent rainwater from infiltrating into the room in the external environment and cause short circuit to cause fire.
4, Protective materials. Generally, the aluminum-plastic panel of the outdoor display product ages faster under high temperature, rain and cold heat, so the rainwater easily penetrates into the screen body in a relatively humid climate, causing a short circuit of the electronic component to cause a fire. In terms of the material of the protective structure outside the display screen, most of the display products with high fire rating on the market adopt refractory aluminum-plastic composite board, which has excellent fire resistance and strong flame retardant performance.
In addition to internal materials that affect fire protection, external design such as heat dissipation is also very important. In the past, large outdoor screens were equipped with electric fans and later developed into internal independent air conditioning. The heat dissipation performance is good, on the other hand, it can prevent fire accidents, on the other hand, it can extend the service life of the display.
