LED plug-in, also known as through-hole LED, is an electronic light-emitting component made of semiconductor materials, mainly used in indoor and outdoor lighting, industrial lighting, automotive lamps, and advertising displays. Its pin number can be divided into two-pin, three-pin, four-pin, and other types, adapting to various scenarios with different specifications.
The device is composed of a bracket, silver paste, chip, gold wire, and epoxy resin. The bracket serves as the conductive and supporting body and is made with a multi-layer plating process.
