Sad! The LED screen at the Hong Kong Coliseum fell and hurt someone! These safety hazards cannot be ignored

On the 28th, a major safety incident occurred on the Hong Kong Coliseum stage: Hong Kong popular idol group Mirror held a concert at the Coliseum. A large LED screen hanging above the stage suddenly fell and hit two dancers who were performing! It is understood that the two actors' spines were injured to varying degrees. One was in a relatively stable condition, while the other was seriously injured and was in a third-level coma when he was sent to the hospital. Currently, this incident has attracted the attention of the Chief Executive of the Hong Kong Special Administrative Region, Lee Ka-chao! It is very sad to see such a scene.

The cause of this security incident is under investigation. At present, this incident has attracted extreme attention from people in the LED display industry, stage performing arts industry, rental construction and other industries. The industry must pay attention to some potential safety hazards in the production, structure, installation and use of LED displays. This is a wake-up call! Safety in the construction of large screens is extremely important. LED fixed screens, stage screens, etc. are usually stacked very high and very large, or are hoisted at high places. There are many actors, audiences, and pedestrians nearby, which raises safety issues. The structural safety of the display screen is an important part of the design and installation process. Due to the short installation time of the LED rental screen, it is impossible to leave a long time to check whether it is firm, so it is particularly important whether the box connection can be quickly checked. In terms of box materials, the application of new materials such as carbon fiber, magnesium alloy, and unique nano-polymer materials can significantly reduce the weight and thickness of the LED display box. The box is lightThinning not only facilitates product installation and maintenance, but also reduces the load on supporting buildings and trusses, making it safer.

To eliminate the safety hazards of LED display screens in stage performances, in addition to the hard work of the manufacturer on the product, the correct installation and use of the LED display screen renter on site is also indispensable. Before the construction of the large screen, a construction party with complete qualifications must be selected. The construction personnel must have relevant construction experience and carry a certificate to work. This is the key to eliminating safety hazards. In order to ensure the safety of stacking and hoisting, LED display lessors and construction parties must strictly abide by the limit on the number of layers for stacking and hoisting, and at the same time choose the correct installation method and high-quality construction materials to avoid safety accidents.

Of course, in addition to the LED large screen involved falling during use, in recent years there have been many large screen collapse accidents caused by factors such as improper construction and unreasonable structures. These safety accidents are worthy of deep thought by the upper, middle and lower reaches of the industry. At the same time, we also need to strictly control every step, even if it is tightening the last small nut.

Safety of use, these problems may increase safety risks beyond the quality of display projects and installation. During the use of LED displays, many factors may cause safety problems, and users need to have certain common sense. For example, the brightness of LED electronic displays near the road should be controlled well. If the brightness is moderate,To bring convenience to pedestrians and vehicles, however, if the brightness of the LED electronic screen is too high, it may cause the yellow line in the middle of the road to be unclear, causing accidents and violations. Overly dazzling video content can also cause accidents caused by pedestrians and driving vehicles looking up at the screen. If indecent content is broadcast, criminal law may apply.

For product safety, manufacturers need to control quality

LED display fire accidents occur from time to time, mostly due to poor product quality and untimely maintenance. Especially in summer, the temperature is very high. After the LED display is lit, it is in a power-on state, so the heat dissipation requirements are also very high. If the cooling air duct design is unreasonable, dust may easily accumulate on the fan spindle, power supply, and motherboard, resulting in various problems such as poor heat dissipation, short circuit of electronic components, short circuit of connecting wires, stuck fan, etc., all of which may lead to fires.

In fact, bad weather will cause damage to LED displays to some extent. Generally, manufacturers will take these factors into consideration within the design scope and conduct corresponding safety protection and testing, but they cannot completely guarantee that their products are foolproof. If the weather deteriorates, be sure to turn off the LED display and conduct a safety test before starting it again. We should also keep up with after-sales service and conduct timely inspections and maintenance.

When choosing products, buyers must recognize theseFor some practical problems, don’t be greedy for cheap, be sure to purchase products that have passed the LED display standards and are from regular manufacturers. Then regular manufacturers must be worthy of their own brands and be responsible for the entire process from the product leaving the factory to installation and maintenance! Regardless of whether it is Party A or the manufacturer, before the large screen is lit, users must receive formal training and standardize the use of LED displays. For example, outdoor LED displays that are exposed to outdoor environments for a long time are easy to be contaminated with dust. You can use alcohol to wipe them, or use a brush or vacuum cleaner to remove dust, but you cannot wipe them directly with a wet cloth. If breaks or other damage are found, they should be replaced in time, especially screws, pins, load-bearing beams, etc.; check the product power distribution system every six months, etc. At the same time, LED display screen manufacturers must control quality. For example, when producing LED outdoor large screens, they must pay attention to the use of fireproof materials, waterproof, dustproof, heat dissipation and other aspects of quality control. If you blindly pursue cost performance, you may destroy the principle of quality control and ultimately lose more than you gain. Written at the end

It is reported that there were potential safety hazards before the story of the big screen falling down in the Hong Kong Coliseum. As long as all aspects of safety inspections are done carefully, the accident may be avoidable. LED stage screens have long been popular around the world. We have enough experience to deal with them, but such serious accidents still occur! The safety alarm bell is ringing again, and the entire bank must put safety first! Finally, I wish the actors injured in this accident and the shocked audience a speedy recovery! We also hope that the entire industry will become more and moreThe more healthy development!
