Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a compact and durable LED bead packaging structure. Background Technology

[0002] When encapsulating the light-emitting chip, wires, and pins, the encapsulation tightly secures them together, preventing them from moving freely. However, to connect the pins to the circuit board, the bottom of the pins extends beyond the encapsulation, exposing them. This can lead to damage to the pins due to collisions during packaging and movement, preventing the LED from being installed on the circuit board. Therefore, this solution proposes a compact and durable LED chip encapsulation structure to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The diagram illustrates a compact and durable LED chip package structure applied to a light-emitting chip 1. The input terminal of the light-emitting chip 1 is electrically connected to a wire 2, and the end of the wire 2 away from the light-emitting chip 1 is electrically connected to a pin 3. The package includes:

[0022] Transparent encapsulating colloid 4 is fitted onto the outer wall of the light-emitting chip 1;

[0023] The protective component 5 includes a retaining ring 502 that is inserted into the bottom of the transparent encapsulating colloid 4. The bottom of the transparent encapsulating colloid 4 is provided with a protective cover 503 for protecting the pin 3. A connector for fixing the position of the protective cover 503 is provided at the connection between the retaining ring 502 and the protective cover 503. A reinforcing member for limiting the movement of the retaining ring 502 is provided at the connection between the retaining ring 502 and the transparent encapsulating colloid 4.

[0024] It should be noted that the light-emitting chip 1, wire 2, and pin 3 are existing structures. The light-emitting chip 1 is the core light-emitting element that converts electrical energy into light energy; the wire 2 is a conductive metal wire that transmits current or signals; the pin 3 is an external metal terminal of the electronic component used for circuit connection; and the transparent encapsulating colloid 4 is an insulating encapsulating material used to protect the light-emitting chip 1, wire 2, and pin 3 and provide light transmission. In use, the top of the fixing ring 502 is encapsulated inside the transparent encapsulating colloid 4, and the connection between the fixing ring 502 and the transparent encapsulating colloid 4 is strengthened by the reinforcing member. Finally, the fixing ring 502 and the protective cover 503 are connected by the connector, thereby fixing the position of the protective cover 503 and protecting the pin 3 to prevent damage to the end of the pin 3.

[0025] Specifically, the connector includes a first thread at the bottom of the retaining ring 502, a second thread at the top of the cover 503, and the cover 503 is threaded onto the bottom of the retaining ring 502.

[0026] It should be noted that the first thread is located on the outer wall of the bottom of the fixing ring 502, and the second thread is located on the inner wall of the top of the cover 503. The first thread and the second thread are compatible, so that the cover 503 is fixed to the bottom of the fixing ring 502 by the first thread and the second thread.

[0027] Specifically, the reinforcing member includes a reinforcing block 501 fixedly connected to the top of the fixing ring 502, which is used to strengthen the connection between the fixing ring 502 and the transparent encapsulating colloid 4.

[0028] It should be noted that the cross-sections of the reinforcing block 501 and the fixing ring 502 are both annular, and the distance between the large and small circles of the reinforcing block 501 is greater than the distance between the large and small circles of the fixing ring 502. By blocking the reinforcing block 501, the connection between the fixing ring 502 and the transparent encapsulating colloid 4 is strengthened, preventing the fixing ring 502 from sliding directly from the bottom of the transparent encapsulating colloid 4.

[0029] Specifically, a fixing plate 6 is inserted and connected to the middle of the fixing ring 502. Multiple heat dissipation fins 7 are provided at the bottom of the fixing plate 6. Multiple through holes are symmetrically opened at the top center of the fixing plate 6. The pin 3 is inserted and connected inside the through holes. Multiple fixing cylinders 8 are symmetrically fixed and connected at the bottom center of the fixing plate 6. The pin 3 is inserted and connected to the middle of the fixing cylinder 8.

[0030] It should be noted that the number of fixed cylinders 8 is the same as the number of pins 3. The cross-section of the fixed cylinder 8 is circular, allowing the pins 3 to pass through the middle of the fixed cylinder 8 and strengthening the connection between the pins 3 and the transparent encapsulant 4. The heat dissipation fins 7 are used to provide a gap between the LED beads and the mounting position, and multiple heat dissipation fins 7 are provided in the gap. The heat dissipation fins 7 increase the heat dissipation surface area and promote air convection to enhance heat dissipation.

[0031] Specifically, the bottom of the protective cover 503 is provided with an anti-slip groove 9, which is used to enhance the friction between the protective cover 503 and the hand.

[0032] It should be noted that the anti-slip groove 9 is designed to increase the contact area between the hand and the protective cover 503, thereby increasing the friction between the hand and the protective cover 503.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
