In recent years, LED displays have become increasingly popular in a variety of social and economic domains as science and technology have advanced. The LED display application sector has emerged as a booming industry with evident advantages and characteristics. With the widespread use of LED displays, people are becoming more aware of their potential safety dangers, particularly fire hazards. Fire mishaps in LED displays represent a major hazard to people’s lives and property, and fire protection methods are desperately needed to address this issue.

At the 2010 Guangzhou International Lighting Festival, a fire suddenly broke out on the LED screen, and the flames quickly spread upward. Although firefighters arrived within a few minutes and put out the fire, the entire screen was destroyed, and the outer wall of the new library was also damaged. On December 16, 2011, improper construction of LED screens in Xizhimen Shopping Center in Beijing caused a fire. In 2012, the LED display at the Harbor Grand Hotel in Hong Kong was struck by lightning and fell into a pile of debris next to the swimming pool, causing a fire in the end. Even the exterior walls of the hotel were blackened. Fortunately, the police and fire trucks arrived in time and finally put out the fire. The fire was put out. On October 27, 2013, a short circuit caused a fire in the LED display in the departure hall of Guangzhou Baiyun Airport, resulting in the security checkpoint being blocked.

Why are LED displays prone to fire? Let’s analyze from multiple factors

First of all, in pursuit of low cost, some manufacturers may employ low-quality cables, connectors, electrical components, and potting glue. Especially under high-temperature conditions in midsummer, these low-quality wires are prone to aging and cracking, which leads to insulation failure and, ultimately, a short circuit and overheating, resulting in a fire. Worse, some cheap potting glue may contain combustible components that cannot be controlled and may exacerbate the fire, posing a major hazard to the safety of persons and property.

Secondly, irregular installation and maintenance are also common causes of fires. LED display screens are usually composed of multiple cabinets spliced together to form a large screen with many power interfaces. Improper installation, incorrect wiring, loose connections, unreasonable wiring and other problems will lead to poor circuit contact, resulting in overheating, which greatly increases the risk of fire.

In addition, we should also pay attention to the circuit layout and power distribution design of the LED display, as well as maintenance timely. The power distribution cabinet that meets the standards can cut off the circuit in time when the LED display power supply line is short-circuited, effectively preventing the occurrence of fire. However, if you want to save costs that use a shoddy power distribution cabinet, you may switch to a high-power air switch and connect multiple power lines to the output end of a large circuit breaker. In this way, once a short circuit occurs in the line, the circuit breaker will not be able to cut off the circuit in time, so lead to fire. In addition, there are too many power cord load boxes in the circuit layout and the load current is too large, which will cause the metal wire core to heat up, accelerate the aging and failure of the insulation layer, cause a short circuit in the circuit and cause a fire. Therefore, proper wiring layout and power distribution design is critical and needs to be planned and executed by professionals.

Finally, correct maintenance is crucial to the fire safety of LED displays. The terminal blocks and connectors of the LED display may become loose due to vibration, thermal expansion and contraction, etc., resulting in poor contact and heat generation, which may lead to fires. Therefore, it is necessary to regularly dispatch maintenance personnel to check the aging of the LED display lines and the tightness of the wiring points. During maintenance, need to tighten loose screws and connectors, and replace wires with aging insulation in a timely manner. For outdoor displays, it is also necessary to check the waterproof performance of the cabinet or screen structure to ensure that there is no hidden danger of water leakage. Only by doing meticulous maintenance work can effectively eliminate fire hazards, and ensure the safety and reliability of LED displays.
