An LED aluminum profile is a type of extruded aluminum used to encase and protect LED strip lights. It helps to distribute the light evenly and gives the strips a finished, professional look. The aluminum also acts as a heat sink, helping to dissipate heat and extend the lifespan of the LED lights. These profiles come in a variety of shapes and sizes to accommodate different lighting applications and can be easily cut to size. They can be mounted to a surface using adhesive backing or mounting clips, and are often used in under-cabinet lighting, cove lighting, and other architectural lighting applications.
