[0038] The following is in conjunction with the appendix Figure 1-4 The LED packaging structure of this utility model embodiment is described.

[0039] The LED packaging structure of this utility model embodiment includes a colloid 1, a light-emitting chip 2, and a bracket 3.

[0040] like Figure 2-4 As shown, the light-emitting chip 2 is disposed within the colloid 1.

[0041] The bracket 3 includes an embedded portion 301 disposed within the colloid 1 and a terminal portion 302 disposed outside the colloid 1. That is, a portion of the bracket 3 is disposed inside the colloid 1, and another portion of the bracket 3 is disposed outside the colloid 1. The portion of the bracket 3 disposed outside the colloid 1 is the terminal portion 302, and the portion of the bracket 3 disposed inside the colloid 1 is the embedded portion 301.

[0042] like Figure 2-4 As shown, a blocking structure 4 is provided around the embedded part 301 on the bonding surface between the embedded part 301 and the colloid 1. The blocking structure 4 divides the embedded part 301 into a mounting part 3011 and a connecting part 3012. The mounting part 3011 is connected to the light-emitting chip 2, and the connecting part 3012 is connected to the terminal part 302.

[0043] Specifically, the blocking structure 4 is disposed on the inner part 301 of the bracket 3.

[0044] It is understandable that the blocking structure 4 provided around the embedded part 301 can divide the embedded part 301 into two parts, one part being the mounting part 3011 and the other part being the connecting part 3012. The mounting part 3011 is used to connect with the light-emitting chip 2, and the connecting part 3012 is used to connect with the terminal part 302.

[0045] Therefore, when external moisture seeps inward through the bonding surface between the embedded part 301 and the colloid 1, the blocking structure 4 can extend the penetration path, thereby achieving the effect of blocking moisture and preventing moisture from seeping further inward. This prevents moisture from entering the light-emitting chip 2, allowing the light-emitting chip 2 to operate stably, extending the lifespan of the light-emitting chip 2, and thus extending the lifespan of the LED.

[0046] The LED packaging structure of this utility model embodiment has good waterproof performance and can also extend the service life of the LED.

[0047] In some embodiments, such as Figure 2 As shown, the blocking structure 4 includes a protrusion 5, which surrounds the embedded portion 301. That is, in this embodiment, the protrusion 5 is connected end to end and surrounds the embedded portion 301. The protrusion 5 divides the embedded portion 301 into a mounting portion 3011 and a connecting portion 3012. The mounting portion 3011 is connected to the light-emitting chip 2, and the connecting portion 3012 is connected to the terminal portion 302.

[0048] Therefore, when external moisture seeps in through the bonding surface between the embedded part 301 and the colloid 1, the protrusion 5 can block the moisture, preventing it from seeping further in and thus preventing it from entering the light-emitting chip 2. This allows the light-emitting chip 2 to operate stably, extending its lifespan and consequently the lifespan of the LED.

[0049] Furthermore, the protrusion 5 and the bracket 3 are integrally formed, which facilitates manufacturing.

[0050] In some embodiments, such as Figure 3 As shown, the blocking structure 4 includes a groove 6, which surrounds the embedded portion 301. That is, in this embodiment, the groove 6 is connected end to end and surrounds the embedded portion 301. The groove 6 divides the embedded portion 301 into a mounting portion 3011 and a connecting portion 3012. The mounting portion 3011 is connected to the light-emitting chip 2, and the connecting portion 3012 is connected to the terminal portion 302.

[0051] Therefore, when external moisture seeps in through the bonding surface between the embedded part 301 and the colloid 1, the groove 6 can block the moisture, preventing it from seeping further in and thus preventing it from entering the light-emitting chip 2. This allows the light-emitting chip 2 to operate stably, extending its lifespan and consequently the lifespan of the LED.

[0052] In some embodiments, such as Figure 4 As shown, the blocking structure 4 includes a protrusion 5 and a groove 6. The protrusion 5 and the groove 6 are connected and arranged around the embedded portion 301. That is, in this embodiment, the protrusion 5 and the groove 6 are connected end to end and arranged around the embedded portion 301. The blocking structure 4 formed by the connection of the protrusion 5 and the groove 6 divides the embedded portion 301 into a mounting portion 3011 and a connecting portion 3012. The mounting portion 3011 is connected to the light-emitting chip 2, and the connecting portion 3012 is connected to the terminal portion 302.

[0053] Therefore, when external moisture seeps in through the bonding surface between the embedded part 301 and the colloid 1, the protrusion 5 and the groove 6 can block the moisture, preventing it from seeping further in and thus preventing it from entering the light-emitting chip 2. This allows the light-emitting chip 2 to operate stably, extending its lifespan and consequently the lifespan of the LED.

[0054] In some embodiments, such as Figure 2-4 The colloid 1 shown also contains a metal wire 7, one end of which is connected to the light-emitting chip 2, and the other end of which is connected to the bracket 3.

[0055] Furthermore, the metal wire 7 can be any one of aluminum wire, copper wire, and gold wire.

[0056] In some embodiments, as shown in the figure, there are 4 brackets 3, which can be divided into two groups. There are 2 light-emitting chips 2. The two light-emitting chips 2 are connected to the two groups of brackets 3 respectively through metal wires 7. That is, one bracket 3 is connected to the two brackets 3 of one group through metal wires 7, and the other bracket 3 is connected to the two brackets 3 of the other group through metal wires 7.

[0057] In some embodiments, there are multiple brackets, which are insulated from each other. The light-emitting chip is connected to two metal wires, which are respectively connected to two brackets.

[0058] In some embodiments, the support is a plate-like structure, which facilitates processing.

[0059] In some embodiments, the support is a metal support.

[0060] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
