How to Exclude the Hidden Risk Outdoor LED Large Screen Spontaneous Combustion ?
LED large screen With the weather warming, long-term work in the outdoor LED power supply is very prone to failure. Spontaneous combustion is a common situation. Wire, power, protective materials have become the key to determine the quality. Four-dimensional Xin photoelectric will introduce you to the outdoor LED large screen some common fire causes:
The general outdoor LED large-screen products with aluminum plate with high temperature, rain and hot and cold impact aging faster, so that in the relatively humid climate season, rain easily penetrate into the screen inside the electronic components lead to short-circuit caused by fire. LED large screen in the external protective structure of the material, the market high fire level high-screen products are mostly using fire-resistant aluminum-plastic panels, the fire resistance is excellent, fire resistance is also very strong.
Plastic kits. The main use of raw materials is a PC fiber with flame retardant function, not only has a flame retardant function, but also in the high and low temperature and long-term use, no deformation, not Will be brittle cracking, combined with good sealing glue used, can effectively block the external environment of the rain into the internal and thus cause short-circuit fire.
Remove the heat problem, the internal raw materials on the fire effect is also a great impact. Especially for large areas of outdoor LED large screen, cooling problem is very difficult. In addition, in the follow-up maintenance of the heat problem also need attention. In short, LED display products need to be careful of the local heat dissipation.
