Is the LED life enough? How to make LED display life of 100,000 hours?
In the projection era, LED display has the same service life as other electronic products. Although the theoretical life of LED is 100,000 hours, it can work for more than 11 years according to 24 hours a day, 365 days a year, but the actual situation and theoretical data are much worse. According to statistics, the life expectancy of LED displays on the market is generally 6~8. In the year, the large LED screen that can be used for more than 10 years is very good, especially the outdoor LED display, the life is even shorter. If we notice some details in the use process, it will bring unexpected results to our display.
From the procurement of raw materials, to the standardization and standardization of the production and installation process, the use of LED display screens will have a great impact. The brand of electronic components such as lamp beads and ICs, to the quality of switching power supplies, are all direct factors affecting the life of LED large screens. When planning the project, we should specify the quality of the reliable LED lamp beads , good reputation of switching power supply, and the specific brand and model of other raw materials. In the process of production, you should pay attention to anti-static measures, such as wearing anti-static rings, wearing anti-static clothes, choosing a dust-free workshop and production line to minimize the failure rate. Before leaving the factory, it is necessary to ensure the aging time as much as possible, and the factory pass rate is 100%. In the transportation process, the product should be packed, and the packaging should be fragile. If it is shipping, it is necessary to prevent hydrochloric acid corrosion.
For outdoor LED display, it is necessary to have necessary peripheral safety equipment, do lightning protection against surge, and try not to use the display during lightning storms. Pay attention to the protection of the environment, try not to put it in a dusty environment for a long time. It is forbidden to enter the water inside the display screen and take measures to prevent rain. Choose the correct cooling equipment, install the fan or air conditioner according to the standard, and the screen environment should be as dry and ventilated as possible.
In addition, the daily maintenance of the LED display is also very important, regularly clean the dust accumulated on the screen, so as not to affect the heat dissipation function. When playing advertising content, try not to be in full white, full green, etc. for a long time, so as to avoid current amplification, cable heating and short circuit failure. When playing a holiday at night, you can adjust the brightness of the screen according to the brightness of the environment, which not only saves energy, but also prolongs the service life of the LED display.
