Anti-corrosion knowledge about LED Lighting
The reliability of LED products is one of the most important specifications used to estimate the life of LED products. Even in most different conditions, general LED products can continue to operate. However, once the LED is corroded, the LED reacts chemically to the surrounding environment, which degrades the performance of the LED product.
In order to avoid corrosion of the LED, the best way is to avoid the LED approaching harmful substances. Even a small amount of harmful substances can cause LED corrosion. Even if the LED is only in contact with corrosive gases during processing, such as machines in a production line, it may have an adverse effect. In these cases, it is usually possible to observe whether the LED components are damaged before the actual system setup. In particular, it should be protected from sulfur (Sulfur).
Below are some examples of potentially corrosive substances (especially hydrogen sulfide) including:
Sulfur-containing vulcanized elastomer
If these hazardous substances cannot be completely avoided, LEDs with higher corrosion resistance should be used. However, keep in mind - limiting the effects of corrosion, depending on the concentration of harmful substances. Even if you choose a more durable LED, you should minimize the exposure of these LED materials.
Generally, heat, humidity, and light can accelerate the corrosion process. However, the most important factor is the concentration level and temperature of the harmful substances. Limiting these two will be the most important method to protect the LED.
