Does the housing of the floodlight rust

2021-08-05

We all know that the floodlights are strong and durable. No matter from appearance or structure, waterproof and heat dissipation performance are the best of LED lamps. This can not be separated from its aluminum shell credit. As a metal material, will the shell of LED floodlight rust?
 
 
Many people think that aluminum is not easy to rust. In fact, aluminum is easier to rust than iron! However, when aluminum rusts, it is still bright, not covered with scars like iron rusts. After aluminum rust, its dense oxide layer tightly adheres to the surface of aluminum, preventing aluminum from continuing to combine with oxygen. Therefore, when using aluminum products at ordinary times, it is not suitable to rub with hard objects to avoid damaging the protective layer of oxide film.
 
 
 
But even so, alumina films also have a killer, which is acid and alkali. When alumina meets them, it will react with them to form compounds, which are very easy to fall off. Therefore, the LED floodlight installed in the outdoor is not acid rain resistant. In addition, the alumina thin feature also hinders the daily cleaning and maintenance of the floodlight.
 
 
 
This requires us not to rub the surface of the lamp with sharp tools when we clean it at ordinary times. If we lose the protective film on the surface, the aluminum pot will continue to oxidize, and the gray color of aluminum oxide will still show in front of you; and the aluminum pot will become thinner and thinner, which will affect its service life.
