In most display screen applications, the larger the display area per unit, the greater the power consumption, and the higher the requirements for the electrical stability of the wiring. Among the numerous wiring products available, only those that meet national standards can guarantee safety and stability. Low-quality wiring poses a hidden fire hazard.
Secondly, the power supply. Power supply products certified by UL are the best choice among similar products. Their efficient conversion rate ensures safe and stable power load, and they can operate normally even in hot external environments.
Thirdly, protective materials. The aluminum composite panels of typical outdoor display screens age quickly due to high temperatures, rain, and thermal shock. This allows rainwater to easily penetrate the screen body during humid seasons, leading to short circuits and fires. In terms of materials for the external protective structure of the display screen, most high-fire-rated display screens on the market use fire-resistant aluminum composite panels, which have excellent fire resistance and flame retardancy.
Fourthly, plastic components. Plastic components are mainly used in the unit module face mask and bottom shell. The main raw material is flame-retardant PC fiberglass material. It not only has flame-retardant properties but also remains undeformed and does not become brittle or crack under high and low temperatures and during long-term use. Combined with a good sealant, it effectively prevents rainwater from penetrating inside and causing short circuits and fires.
In addition, besides the internal raw materials affecting fire prevention, external designs such as heat dissipation are also very important. Maipu Optoelectronics LED outdoor display screens operate at high temperatures, making heat dissipation a major challenge. For large-area display screens, the difficulty of heat dissipation is even greater. Previously, outdoor large screens used fans for auxiliary cooling, but later they developed to include internal air conditioning systems. Good heat dissipation performance can prevent fire accidents and extend the lifespan of the display screen.
Of course, fire incidents are also related to local environmental factors such as temperature and humidity, as well as human error. High temperatures, high humidity, heavy rain, lightning strikes, and improper operation by construction technicians can all easily trigger accidents.
Understanding the causes of fire accidents allows for targeted preventive measures, which will contribute to the harmonious construction of a safe social environment.
