Common sense for LED screen selection and maintenance. At present, LED screens are closely related to people who do business. They can be seen in small jewelry 2 yuan stores, clothing stores, and convenience stores, as large as shopping malls, supermarkets, airports, and docks. Now the commercial atmosphere is very strong, and the LED screen can play a very good role in promoting the spread of advertisements. LED screens, like other electronic products, have a service life. Although the theoretical life of LED is 100,000 hours, it can work for more than 11 years based on 24 hours a day and 365 days a year, but there is still a gap between the actual situation and the theoretical data. According to statistics, the life of LED screens on the market is generally 6 ~12 years, a large LED screen that can be used for more than 10 years is considered very good, especially for outdoor LED screens, the life span is even shorter.
If we pay attention to some details during use, it will bring unexpected effects to our LED screen. For outdoor LED screens, necessary peripheral safety equipment must be provided, and lightning protection and surge protection measures must be taken. Try not to use LED screens in thunderstorm weather. Pay attention to the protection of the environment, try not to put it in a dusty environment for a long time, it is strictly forbidden to enter the inside of the LED screen, and take rainproof measures.
Choose the correct heat dissipation equipment, install the fan or air conditioner according to the standard, and make the screen environment as dry and ventilated as possible. From the procurement of raw materials to the standardization and normalization of the production and installation process, it will have a great impact on the service life of the LED screen. The materials of electronic components such as lamp beads and ICs, and the quality of switching power supplies are all direct factors that affect the life of LED large screens.
When we plan the project, we should specify reliable quality LED lamp beads, good reputation switching power supply, and other accessories with better materials. In the process of production, we must pay attention to anti-static measures, such as wearing anti-static rings, wearing anti-static clothes, and choosing dust-free workshops and production lines to minimize the failure rate. Before leaving the factory, it is necessary to ensure the aging time as much as possible to achieve a 100% factory pass rate.
During the transportation, the product should be packaged well, and the fragile product should be marked on the outside of the package. If it is shipped by sea, it is necessary to take anti-hydrochloric acid corrosion measures. In addition, the daily maintenance of the LED screen is also very important. Regularly clean the dust accumulated on the LED screen so as not to affect the heat dissipation function. When playing advertisement content, try not to stay in all white, all green and other screens for a long time, so as not to cause current amplification, cable heating and cause short circuit and other faults.
When playing festivals at night, the brightness of the screen can be adjusted according to the brightness of the environment, which can not only save energy, but also prolong the service life of the LED screen. .
