How to avoid LED corrosion

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, the general LED products can continue to work. However, once the LED is corroded and the LED is subjected to chemical reactions by the surrounding environment, the performance of LED products will be reduced.



In order to avoid LED corrosion, the best way is to avoid the LED close to harmful substances. Even small amounts of harmful substances can cause LED corrosion. Even if the LED is only in contact with corrosive gases during processing, such as machines in the production line, there may be adverse effects. In these cases, it is usually possible to see if the LED component is damaged before actually setting up the system. In particular, Sulfur contamination should be avoided.



Here are some examples of potentially corrosive substances (particularly hydrogen sulfide) including:

O-ring (O - RING)

The gasket

Organic rubber

Foam pad

The sealing rubber

Sulfur elastomer

Anti-shock pad

If these harmful substances cannot be completely avoided, leds with higher corrosion resistance should be used. However, keep in mind that the effect of limiting corrosion depends on the concentration of the harmful substance. Even if you choose a more durable LED, you should minimize the exposure of these LED materials.



In general, heat, humidity, and light speed up the corrosion process. However, the most important factors are the concentration level and temperature of harmful substances. Limiting these two factors will be the most important method to protect LED.
