How to rule out spontaneous combustion of outdoor LED display
Some LED power supplies that work outdoors for a long time are very prone to failure. Spontaneous combustion is a common occurrence. Wires, power supplies, and protective materials have all become the keys to determining quality. Here are some common fire causes of LED displays.
The aluminum-plastic panels of general outdoor LED display products age rapidly with high temperature, rain and cold and heat shocks, so that in relatively humid climates, rain and dew easily penetrate into the interior of the screen, resulting in short-circuiting of electronic components and causing fires. In terms of the material of the external protective structure of the display screen, most of the display products with high fire rating on the market are made of fire-resistant aluminum-plastic panels, which have excellent fire resistance and strong fire resistance and flame retardancy.
plastic kit. The plastic kit is mainly the material used for the bottom shell of the unit module mask. The main raw material is PC glass fiber material with flame retardant function. It will become brittle and crack, and at the same time, it can be used in combination with glue with better sealing performance, which can effectively prevent the rainwater from the external environment from penetrating into the interior, causing a short circuit and fire.
In addition to the heat dissipation problem, the internal raw materials also have a great influence on the fire protection effect. Especially for large-area display screens, the problem of heat dissipation is very difficult. In addition, the heat dissipation problem also needs to be paid attention to in the follow-up maintenance. In short, the heat dissipation of LED display products requires developers to be careful everywhere.
