[0003] The existing LED lamp beads have insufficient bonding strength between the encapsulation glue and the bracket lamp cup, which causes the encapsulation glue to easily fall off, thus affecting the light efficiency and reliability of the LED lamp beads. Especially in harsh working environments such as high temperature, high humidity, and high pressure, the thermal stress and mechanical stress between the encapsulation glue and the bracket lamp cup or substrate will increase, accelerating the aging and falling off of the encapsulation glue. In addition, the falling off or cracking of the encapsulation glue will also cause the anti-sulfurization performance of the LED chip to decrease, making the LED chip susceptible to corrosion by harmful gases such as hydrogen sulfide, thereby reducing the life of the LED lamp beads.

[0004] Therefore, how to improve the bonding strength between the encapsulation glue and the bracket lamp cup or substrate, prevent the encapsulation glue from falling off or cracking, and improve the reliability and life of the LED lamp beads is an urgent problem to be solved in the LED lamp bead packaging structure technology.
