The positive and negative ends of the beads are directly welded on the front of the aluminum substrate, and the back of the aluminum substrate is in contact with the inner plate of the lamp holder (lamp housing) by coating a thermally conductive paste such as silicone grease. This manufacturing process is not only complicated but also has disadvantages: due to the existing The LED lamp bead uses an aluminum substrate as the electrical substrate and the heat dissipation effect is not ideal by coating heat-conducting silicone grease. The LED lamp is easily affected by high temperature during use and the efficiency is reduced, which not only wastes power but also shortens the service life of the LED. And if it is because of the damage of any small component of the driving power supply or the damage of any lamp bead, the change of instantaneous voltage and current will cause other lamp beads to be damaged successively, so that the whole LED lamp cannot be used and all are scrapped.
