How to eliminate hidden dangers of outdoor LED screen?

LED screenas the weather heats up , some LED power supplies working outdoors for a long time are very prone to failure . Spontaneous combustion is a common situation . Wire , power supply and protective materials have become the key to determine the quality . Siweixin optoelectronics will introduce some common fire causes of outdoor LED display screen. 

The aluminum-plastic plate of general outdoor LED large screen products age rapidly with the impact on high temperature , rain , cold and heat , so that it is easy about rain and dew to penetrate into the interior of the screen in humid weather seasons , resulting in short circuit of electronic components and fire . In terms of the materials of the external protective structure of LED large screen , most of the large screen products of high fire rating on the market use fireproof aluminum-plastic plate , which has excellent fire resistance and strong fire resistance . 

Plastic kit . The plastic kit are mainly used as the material for the bottom shell of the unit module mask . The main raw material is PC glass fiber material with flame retardant function . It not only has flame retardant function , but also does not to deform , brittle and crack under high and low temperature and long-term use . At the same time , it is used in combination with glue with good sealing performance , which can effectively block the rainwater from the external environment from penetrating into the interior , resulting in short circuit and fire . 

In addition to the problem of heat dissipation , the internal raw materials also have a great impact on fire prevention effect . Especially for large-area outdoor LED screens , heat dissipation is very difficult . In addition , the problem of heat dissipation also needs attention to subsequent maintenance . In short , the heat dissipation of LED displaysproducts requires developers to be careful everywhere .
