a waterproof bracket 10; a housing 11; a metal pin 12; a first lead segment 121; a second lead segment 122; a third lead segment 123; a fourth pin segment 124; a fifth pin segment 125; a functional region 20; a chip 21; a filler 22; a metal lead 23.
Detailed Description
As shown in fig. 2, the present invention discloses an LED package structure for an LED display, which includes a waterproof support 10, a functional region 20 is formed on the waterproof support 10, and the functional region 20 is provided with a chip 21 and a filler 22; the waterproof support 10 comprises a metal pin 12 and a shell 11 wrapping the metal pin 12, and the chip 21 is electrically connected with the metal pin 12 through a metal lead 23.
The metal pin 12 includes a first pin segment 121, a second pin segment 122, a third pin segment 123, a fourth pin segment 124, and a fifth pin segment 125, where the first pin segment 121 is close to the functional region 20, the fifth pin segment 125 is far from the functional region 20, and the first pin segment 121 and the fifth pin segment 125 are parallel. The first lead section 121 is connected with the second lead section 122, and the two lead sections form an included angle of 90 degrees; the fourth lead section 124 is connected with the fifth lead section 125, and an included angle of 90 degrees is formed between the fourth lead section and the fifth lead section; the second lead section 122 is located outside the fourth lead, and the second lead section and the third lead section 123 are connected to form an inflection point at the third lead section 123.
