High power LED beads can operate continuously under most different conditions. However, once the LED beads are corroded, they will undergo chemical reactions with the surrounding environment, which will reduce the performance of the LED beads.
Avoiding corrosion of LED beads is an important step in improving the reliability of LED beads. The reliability of LED beads is one of the important specifications used to estimate the lifespan of LED bead products. Tongjia Optoelectronics analyzed the reasons for the corrosion of LED beads and provided methods to prevent them from being corroded - to avoid LED beads approaching harmful substances, and to effectively limit the concentration level and environmental temperature of harmful substances.
In order to prevent LED lamp beads from being corroded and contacting with harmful substances such as O-ring, gasket, organic rubber, foam pad, sealing rubber, sulfurous elastomer, shock pad, etc.
Even a small amount of harmful substances can cause LED bead corrosion. Even if LED beads only come into contact with corrosive gases during the processing process, such as machines in the production line, it may still have adverse effects. In these cases, it is usually possible to observe whether the LED bead components are damaged before actual system setup. If LED beads cannot completely avoid these harmful substances, LED beads with higher corrosion resistance should be used.
Reminder: The effectiveness of LED lamp beads in limiting corrosion depends on the concentration of harmful substances. Even if you choose more durable LED beads, you should try to minimize the exposure of these LED bead materials. Usually, heat, humidity, and light can accelerate the corrosion process. However, the main influencing factors are the concentration level and temperature of harmful substances, and limiting these two factors will be an important and reasonable method to protect LED lamp beads from corrosion.
