Abstract
A visible light communication LED having a spiral inductance coil and a circular core is provided, comprising a sapphire substrate provided with a positive electrode welding spot and a negative electrode welding spot, and a plurality of LED cores deposited on the sapphire substrate. The negative electrode of a former core is connected with the positive electrode of a latter core, and the positive electrode of the first core and the negative electrode of the last core are respectively connected to the positive electrode welding spot and the negative electrode welding spot on the substrate. According to the present invention, each of the LED cores is surrounded by a spiral inductance coil, and a pin of one end of the spiral inductance coil is connected via a connecting wire with the negative electrode of an adjacent LED core, while the other end is directly connected with the positive electrode of the LED core that is surrounded by the spiral inductance coil.
