LED light bead material knowledge point
‌      The core materials of LED lamp beads include wafer, bracket, silver glue, gold thread and epoxy resin. ‌ chip is a PN junction composed of P and N layers of semiconductor elements, which is rearranged and combined by electron movement. The 
      bracket consists of a multi-layer structure consisting of iron, copper, nickel and silver layers to ensure electrical conductivity, heat dissipation and oxidation resistance. argentol
      It acts as a conductor and bond, while the gold wire connects the chip and the bracket to form a closed circuit. Finally, the epoxy resin is used to seal and protect the lamp beads from the external environment ‌.
      In addition, the material of LED lamp beads also includes some specific semiconductor materials, such As gallium (Ga) and arsenic (As), phosphorus (P) compounds. These materials radiate visible light when electrons are combined with holes,    
     allowing leds to emit light in a variety of colors. With the development of technology, the material of LED lamp beads continues to improve, such as the use of better thermal materials
     Materials and more efficient luminous materials to improve the efficiency and life of LED lamps ‌.
