How to Avoid LED Beads Corrosion

LED beads can operate continuously under most different conditions. However, once the LED beads are corroded, they will be subjected to chemical reactions from the surrounding environment, thereby reducing the performance of the LED beads. Avoiding LED bead corrosion is an important step in improving LED bead reliability. The reliability of LED lamp beads is one of the important indicators used to estimate the lifetime of LED lamp beads. Tongjia Optoelectronics analyzed the causes of LED lamp bead corrosion and provided methods to avoid LED lamp bead corrosion - avoiding LED lamp beads approaching harmful substances, effectively limiting the concentration level and ambient temperature of harmful substances

To prevent LED lamp beads from being corroded, avoid contact with harmful substances such as O-ring, gasket, organic rubber, foam pad, sealant, sulfur-containing vulcanized elastomer, shock pad, etc. Even small amounts of harmful substances can cause LED lamp beads to corrode. Even if LED lamp beads are only exposed to corrosive gases during processing, such as machines on the production line, they may have adverse effects. In these cases, it is usually possible to observe LED components for damage before actual system setup. If LED beads cannot completely avoid these harmful substances, LED beads with higher corrosion resistance should be used. Finally, I would like to remind everyone that the corrosion limiting effect of LED lamp beads depends on the concentration of harmful substances. Even if you choose more durable LED beads, you should minimize the exposure of these LED bead materials. In general, factors such as heat, humidity, and light can accelerate the corrosion process. However, the main influencing factors are the concentration level and temperature of harmful substances. Limiting both will be an important and reasonable way to protect LED lamp beads from corrosion.
