On the evening of April 8, 2017, an LED display outside a hotel in jinzhou caught fire.Some time ago, I saw the video screen of led screen catching fire in the circle of friends. Therefore, delenser once again reminded us that we should never be cheap when buying led screen and other electronic products. We should treat the price rationally.

At 9 o ‘clock on October 27, 2013, a fire broke out in a store in the waiting hall of guangzhou baiyun airport. Ashes were flying all over the place, and the fire was spreading continuously. The security check entrance in area B was closed, and the late baggage collection office near area B was closed and unable to be used.According to baiyun airport, at 9:13 a.m. on October 27, a fire broke out outside a shop in the departure hall of baiyun airport. It was preliminarily determined that a short circuit of an LED display wire in the departure hall caught fire.

On December 16, 2011, Beijing xizhimen shopping center caught fire, which was caused by improper LED screen construction. At the end of the same month, the LED screen of traffic building in yueqing city, zhejiang province suddenly caught fire. Fortunately, no casualties were caused in the two accidents.

So what causes so many led screen fires?Let‘s take a look at the following points:

1. The wire rod on the market can be said to be of spotty quality, the spool of a lot of inferior wire rod is to use copper to wrap aluminium, the appearance looks copper wire, basically be aluminium alloy actually, this kind of line can use as temporary wire rod only, do not have method to use at all come in normal product.

2. Poor quality power supply, or low power, or long-term overload operation of power supply.

3. Poor led PCB materials, unreasonable design and poor process lead to burr of copper wire, which eventually leads to short circuit, which is the main cause of fire.
