AI Technical Summary
When cutting the existing LED brackets, the packaging glue is prone to cracking and breaking, resulting in low yield of LED lamp beads, poor sealing effect, and internal stress caused by differences in hot and cold shrinkage affects the packaging effect.
A stable LED bracket is designed. By recessing to the inner side of the pin at the first transition part and the second transition part and providing reinforcement strips on the outside, the first connection part and the second connection part gradually become larger, so that the thickness of the packaging rubber near the cutting end is increased, reducing the damage to the packaging rubber by cutting force, and at the same time, the packaging rubber is filled through the through hole of the bracket bowl and cup to suppress the detachment force.
It improves the yield rate of LED lamp beads, enhances the stability and sealing effect of the packaging glue, and reduces the risk of the packaging glue being separated from the bracket.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to a stable LED bracket. Background Art
[0002] An LED bracket is a bracket for installing an LED chip. A straight-pin LED bracket is a type of LED bracket. After the LED chip is fixed on the LED bracket, the chip is encapsulated inside a colloid by potting, so that the chip is isolated from the outside world. Then, the bracket is separated from the row of brackets by cutting to form single LED lamp beads. However, in the prior art, the thickness of the encapsulation glue covering the outside of the bracket is smaller at the part near the cutting end of the bracket. When the bracket is cut, affected by the cutting force, the encapsulation glue at this part is prone to cracking and breaking, resulting in a low yield rate of LED lamp beads and poor sealing effect. At the same time, due to the difference in the shrinkage ratio of the bracket and the encapsulation glue used for encapsulation under different hot and cold conditions, the internal stress formed causes the encapsulation glue in the bracket bowl to separate from the bracket bowl, affecting the encapsulation effect. Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to improve the prior art. Summary of the Utility Model
