LED bracket, the bottom base of the LED lamp bead before packaging. On the basis of the LED bracket, the chip is fixed in, the positive and negative electrodes are welded, and then the encapsulation glue is used to form the package. The LED bracket is generally made of copper (also made of iron, aluminum, ceramics, etc.). Because copper has good conductivity, there are leads inside it to connect the electrodes inside the LED lamp beads. After the LED lamp beads are packaged and formed, the lamp The bead can be removed from the bracket, and the copper feet at both ends of the lamp bead become the positive and negative electrodes of the lamp bead, which are used for welding to LED lamps or other LED finished products.
