           High power LED beads can operate continuously under most different conditions. However, once the LED lamp beads are corroded, the LED lamp beads will have a chemical reaction by the surrounding environment, which will reduce the performance of the LED lamp beads.

          To avoid corrosion of LED lamp beads is an important step to improve the reliability of LED lamp beads. The reliability of LED lamp beads is one of the important specifications used to estimate the service life of LED lamp beads. Tongjia optoelectronics analyzed the causes of LED lamp bead corrosion, and gave the methods to avoid LED lamp bead corrosion - to avoid LED lamp bead from approaching harmful substances, and to effectively limit the concentration level and ambient temperature of harmful substances.

          In order to avoid corrosion of LED lamp beads, avoid contacting O-ring, gasket, organic rubber, foam pad, sealing rubber, sulfur containing vulcanized elastomer, shockproof pad and other harmful substances.

          Even a small amount of harmful substances will cause led bulb corrosion. Even if the LED lamp beads are only in contact with corrosive gases during processing, such as machines in the production line, it may have adverse effects. In these cases, it is usually possible to observe whether the LED bulb assembly is damaged before the actual system setting. If these harmful substances cannot be completely avoided, LED lamp beads with higher corrosion resistance shall be used.

          Remind everyone: the effect of LED lamp beads on corrosion restriction 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. 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 factors will be an important and reasonable method to protect LED lamp beads from corrosion.
