Problems solved by technology

[0004] The insulating isolation strip between the positive electrode substrate and the negative electrode substrate is perpendicular to the long side of the support and arranged parallel to the positive electrode substrate and the negative electrode substrate; and the insulating isolation strip is made of relatively fragile insulating plastic material, and the width of the insulating isolation strip is narrow , leading to a small amount of plastic in the insulation isolation belt, and the insulation isolation belt is prone to breakage, which reduces the overall strength and reliability of the LED bracket and the LED made by using the bracket;
[0005] The wall contact area and functional area on the front of the positive electrode substrate 11 and the negative electrode substrate 12 are all located on a plane, so when the moisture spreads to the front of the substrate along the junction of the side of the substrate and the plastic wall 10, it is easy to pass through the wall on the front of the substrate. The contact area enters the functional area, resulting in short circuit of the circuit in the functional area, damage to the device or even directly causing dead lights; and most of the functional area of ​​the substrate is plated with a metal silver layer, and the metal silver layer is also easy to corrode under the action of moisture, resulting in functional failure. sexual defect
It can be seen that the moisture-proof performance of the existing LED bracket and the LED made by using the bracket is poor
