In recent years, LED display screens have occurred or accidents involving LED display screens have occurred frequently, causing serious losses to the lives and property safety of the people.
On May 18, 2019, a giant LED advertising screen in Times Square, New York, USA caught fire and was still playing advertisements when it caught fire.
On April 28, 2019, a fire broke out on the large LED screen of a building on Luolai Square in Minhang District, Shanghai. Smoke billowed and open flames continued.
On the evening of April 8, 2017, the external LED display of Yuandu Hotel in Jinzhou City caught fire. The fire department rushed to the scene to put out the fire. Fortunately, no casualties were caused.
On October 27, 2013, a short circuit of the LED display wire in the departure hall of Guangzhou Baiyun Airport caused a fire, which caused the security checkpoint to be blocked.
So, what are the reasons for the frequent occurrence of LED display fire accidents? How should the LED display screen do a good job of fire prevention? Dakco, which is committed to becoming "the most concerned security LED display brand", has always focused on this issue. According to Dakco technical experts, there are three main sources of LED display fires: LED display module assembly has no quality assurance, products have no overall fire protection design, and installation and maintenance are not standardized.
It can be seen that the risk of using unsecured modular assembly screen products is the greatest. Irregular production environment, process flow, non-professional operation, and non-standard installation are the main reasons for the LED display to catch fire.
Through further analysis of the key fire points of the module assembly screen, it can be found that: at the AC end of the power supply, poor contact is mainly caused by irregular wiring and loose connectors, which leads to ignition and fire. On the DC side of the power supply, it is because of the use of inferior terminals and wires, overcurrent caused overheating and fire.
In addition, unlicensed operation by non-professionals, pests and rats, causing short circuits, exposed wires without protection, replacement of insulating plates with foam cotton, fast aging of uncertified wires, large resistance, and small diameter are also key factors that cause fires.
As a company with 90% of its markets in developed countries such as Europe, America and Japan, and with a sense of social responsibility, Dakco attaches great importance to the safety of people's lives and property. Relying on the company's nearly 15 years of technical accumulation and project experience in the LED display industry, supported by factual data and professional analysis, aiming at the common fire safety hazards of LED module assembly screens, and combining European and American safety standards, the LED display has been launched The "branded machine" product Genesis column.
Compared with the LED module assembly screen using low-cost raw materials, the production process is not standardized, the quality is not strictly controlled, and the LED display panel fires frequently caused by the installation without guarantee. Dakco’s led display has 4 major advantages in terms of fire safety:
1. Using high-quality raw materials: Dakco selects high-quality PCBs, international brand power supplies, national standard wire materials and other raw materials, and the key raw materials have a fire rating of UL94-V0 in the United States. Strict safety testing standards are implemented to prevent leakage and fire;
2. Production process specifications: Dakco's manufacturing base has ISO certification, and the products have undergone at least 18 production and assembly processes, and have passed factory tests such as safety regulations, high and low temperature, waterproof, vibration, and aging. The work is regulated by professionally qualified workers and there are few human errors. The whole machine adopts a closed design, the wiring is neat, dustproof, fireproof, and rodent-proof;
3. Whole-process quality control: The product has gone through 18 monitoring links, 29 operation processes, 33 recording links, 2285 monitoring experiments, and has passed 3C certification and obtained CNAS accreditation;
4. Standardized installation: The whole machine comes with its own branded power supply, receiving card, etc., with strict safety control. The installation process is standardized, manageable and controllable. Certified service engineers strictly follow the construction standards, and the project quality is guaranteed.
Therefore, choosing safe and reliable products is the first step to prevent fires. The use of Dakco's Gen series, effectively eliminates the fire hazard of the LED display.
