We all know that floodlights are strong and durable. Regardless of appearance or structure, waterproof and heat dissipation performance are the best in LED lamps. This is thanks to its aluminum casing. As a metal material, will the housing of the LED flood light rust?
Many people think that aluminum is not easy to rust. In fact, aluminum is easier to rust than iron! However, aluminum is still beautiful when it is rusted, and it is not covered with scars like when iron is rusted. After the aluminum is rusted, its dense oxide layer is tightly attached to the surface of the aluminum, preventing the aluminum from continuing to combine with oxygen. Therefore, when using aluminum products, it is not advisable to rub with hard objects, so as not to damage the protective layer of the oxide film. But even so, the aluminum oxide film has its nemesis, that is, acid and alkali.
When aluminum oxide encounters them, a chemical reaction occurs, forming compounds that are very easy to fall off. Therefore, the LED floodlight installed outdoors is not resistant to acid rain, and the thin aluminum oxide also hinders the daily cleaning and maintenance of the floodlight.
This requires us not to use sharp tools to rub the surface of the floodlight when cleaning. If the protective film on the surface is lost, the aluminum pot will continue to oxidize, and the gray color of aluminum oxide will still be displayed in front of your eyes; The pan is getting thinner and thinner, affecting its lifespan.
