With the rapid development of modern science and technology, China's LED display industry sustained growth and industry size have been expanding. The market share continued to grow by an annual average growth rate of 40% from 1993 to the present. However, the fire incident of Hong Kong Harbour Grand knocked a wake-up call to entire LED display industry. With the rapid growth of LED display industry, the technology of LED display security applications remaining short board, LED products standardization and standardization again on the agenda. In particular, LED display fireproof safety application techniques is the focus. Here, we will see what factors will affect the fireproof issues of LED display.
The quality of the LED display fireproof performance are closely associated with raw materials and cabinet process. The fireproof materials mainly include wire, power supply, external protection, external structural fireproof materials and plastic kit.
In most LED display applications, the greater display area, the more power consumption, which also have higher requirements on the power stability of the wire. The wire in line with GB requirements to be able to guarantee its security and stability.
Power products have UL approved are also the best choice, its effective conversion rate ensure power load security and stability. It can work in the external ambient temperature of the hot case.
In the external structural fireproof materials, higher fireproof rating LED display products are using of aluminum composite panel, which has excellent fire resistance. The aluminum composite panel of outdoor LED display products aging rapidly, rain is easy to penetrate the screen inside and leading to electronic components short circuit or cause fire.
There is an important part of display fireproof materials, that is plastic kit. Plastic kit is the materials of the unit modules mask, the main raw materials are PC and fiberglass materials. It can effectively block the rain penetration into internal and avoid to cause fire.
