High-power LED lamp beads can continue to operate under most different conditions. However, once the LED lamp bead is corroded, the chemical reaction of the LED lamp bead by the surrounding environment will reduce the performance of the LED lamp bead.
Avoiding corrosion of LED lamp beads is an important part of improving the reliability of LED lamp beads. The reliability of LED lamp beads is one of the important specifications used to estimate the life of LED lamp beads. Tongjia Optoelectronics analyzed the causes of corrosion of LED lamp beads and gave ways to avoid LED lamp beads from being corroded-avoiding LED lamp beads from approaching harmful substances, and effectively limiting the concentration level of harmful substances and the ambient temperature.
In order to avoid corrosion of LED lamp beads, avoid contact with harmful substances such as O-rings, gaskets, organic rubber, foam pads, sealing rubber, sulfur-containing vulcanized elastomers, and shock-proof pads.
Even a small amount of harmful substances can cause corrosion of LED lamp beads. Even if the LED lamp bead is only in contact with corrosive gas during processing, such as the machine in the production line, it may have an adverse effect. In these cases, it is usually possible to observe whether the LED lamp bead assembly is damaged before the actual system setup. If LED lamp beads cannot completely avoid these harmful substances, LED lamp beads with higher corrosion resistance should be used.
Remind everyone: the effect of LED lamp beads to limit corrosion depends on the concentration of harmful substances. Even if you choose more durable LED lamp beads, you should minimize the exposure of these LED lamp beads. Generally, heat, humidity and light can accelerate the corrosion process. However, the main influencing factors are the concentration level and temperature of harmful substances. Limiting these two will be an important and reasonable method to protect LED lamp beads from corrosion.
