WCBA Beijing home LED advertising screen burned the scene smoke smoke

On February 18th, WCBA semi-final round match Beijing's match against Shanghai at Shougang stadium, in the second quarter of the game, the home court LED billboards burned smoke scene, become an episode of fierce confrontation among the parties.

This is the scene soon began to play in the second quarter, the first section of the game after the end of the Beijing women's basketball team to 23-22, 1 points ahead of the competition, while the two sides fight to the fans watching at home court Nanshenanfen when suddenly asked the pungent smell, to be looked up, I found it was the scene of a a LED billboard burned, venue suddenly smoke rising, and the order was also part of chaos, the audience stood up his nose to leave the seat.

But the episode did not affect the continuation of the match, in quite a part of the time, both players can only smell the smell of smoke in the air filled with coke in the field continue to fight, to become the WCBA stadium for a large number of wonders, this event also attracted many fans attention. Micro-blog named Guo Jianyuan @_ _ users in which micro-blog quipped: "this is the real smell of gunpowder! "

Causes of the fault current still can make nothing of it, but it is worth mentioning that, in the domestic similar LED screen burn out is not the first incident, in yesterday's Qinhuai District Nanjing Longpan Road No. 450 building facades, it has a large LED screen burn smoke rose, then the fire brigade rushed to the to control the fire did not let down the further deterioration of the situation, but before this, in 2012 April 23rd, the Hongkong harbour grand hotel for LED LCD screen burn fire occurred, a total of more than and 300 people were evacuated, but relatively large public places, relatively more gathered in the basketball hall in such a small area, stream of people what the risk is clearly more, not after this incident, the unit will not be repaired in a timely manner, to avoid the recurrence of similar things.

China LED Xiaobian think: LED display fire hazard, is still some short board raw materials. First, wire. In most display applications, the greater the unit area of the display screen, the greater the power consumption, the higher the demand for the stability of the wire. Many wire products, the use of wire in line with the requirements of national standards to ensure its safety and stability. Second, power. UL certified power supply products is the best choice for similar products, the effective conversion rate can ensure the security and stability of power supply load, in the external environment, the temperature is hot, but also can work properly. Third, protective materials. Aluminum plate general outdoor display products with high temperature, rain and cold shock aging faster, so the climate humid rain season period, easy to penetrate the screen body internal cause electronic components caused by short circuit fire. In the external protective structure display materials market, high fire rating display products are mostly made of fireproof aluminum plate, its excellent fire resistance, fire retardant is also very strong. Fourth, plastic kit. Plastic package is mainly used material module mask the bottom shell of the unit, the main raw material is PC glass fiber materials with flame retardant function, not only has the flame retardant function, more in high temperature and long time use, no deformation, no brittle cracking, combined with good sealing glue, can effectively block the external environment the water penetration into the internal fire caused by short circuit.

In addition to the internal raw materials will affect the fire effect, heat dissipation and other external design is also very important. LED outdoor display at high temperatures, power consumption is a big test, if it is a large area of the display, but also increased the difficulty of heat. Before the big screen is the use of fans and other auxiliary heat dissipation, and later developed into the self installed air conditioning facilities. In addition, we can not ignore the factors that are considered in the late maintenance project. In short, the LED display of the fire problem needs to be careful everywhere.
