summer is coming, the high temperature of outdoor advertising P6 P8 P10 led display screen has gradually come into our sight. in recent years, a variety of problems such as spontaneous combustion of led display screen appear, so-called prevention is in the bud, so how can we prevent such problems? today we will take you to understand the main causes of led spontaneous combustion and prevention methods.
the causes of spontaneous combustion of led can be roughly divided into four categories:
1. high temperature
because the outdoor high temperature in summer is continuously burning the led display screen, coupled with its own continuous work will produce a lot of heat, resulting in serious lack of product heat dissipation, it is easy to cause product components temperature is too high, causing damage, thereby causing fire.
2. circuit short circuit
there are many factors that cause this problem, one is the short circuit caused by improper operation of operators; the other is frequent rain in summer and lack of necessary maintenance of the display screen in peacetime, which leads to wet short circuit of the circuit environment, thus causing fire.
3. material quality of product
in production and manufacturing, some companies in order to save costs, such as pcb, fire-proof raw materials and so on have not reached the corresponding fire-proof grade, to the second best; in product design, some companies blindly pursue high brightness by increasing the current without breaking through the core raw materials such as lamp beads, thus causing fire.
