Detailed implementation manners

[0052] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B; herein, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

[0053] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0054] As Figures 1 - 5 shown, a light - emitting diode (LED) light bulb 200 is provided, which includes a light source, a lamp housing 1, and a plurality of electrical contacts 2. The light source includes lamp beads 3, and each electrical contact 2 is electrically connected to the corresponding connection end of the lamp bead 3. The electrical connection can be achieved by means such as patch welding, snap - connection, etc., but is not limited thereto; the lamp beads 3 are encapsulated by a waterproof colloid 4. In this embodiment, the lamp beads 3 are LED lamp beads with red - green - blue (RGB) functions.

[0055] The lamp housing 1 is formed by injection molding; it can be understood that in some embodiments, the lamp housing 1 can also be formed by other processing methods.

[0056] As Figures 1 - 3As shown, two electrical contacts 2 are electrically connected to the lamp bead 3; alternatively, as Figures 4 - 5 shown, three electrical contacts 2 are electrically connected to the lamp bead 3; it can be understood that in some embodiments, the number of electrical contacts 2 can also be 4, 5, 6, etc., but is not limited thereto.

[0057] The bulb 200 further includes a glue core 5. One end of the glue core 5 is formed with a mounting hole 51, and the other end of the glue core 5 is formed with a through hole 52; the through hole 52 communicates with the mounting hole 51, and the lamp bead 3 is connected to and supported by the glue core 5.

[0058] The lamp bead 3 is located inside the lamp housing 1; it can be understood that in some embodiments, the lamp bead 3 is located inside the mounting hole 51.

[0059] One end of the lamp housing 1 facing the glue core 5 has a cavity structure with an opening and is inserted into the mounting hole 51.

[0060] Each electrical contact 2 sequentially passes through the mounting hole 51, the through hole 52, and bends towards the outside of the through hole 52 and extends towards the outer wall of the glue core 5.

[0061] The electrical contact 2 is a bent pin; it can be understood that in some embodiments, the electrical contact 2 can also be of other shapes.

[0062] It should be noted that in this embodiment, the bulb 200 is matched with the lamp socket 8 of the string light. The power cord 6 is provided with connection tabs 9 corresponding to the respective electrical contacts 2; during the process of installing the bulb 200 into the lamp socket 8, each connection tab 9 is pressed by the lamp socket 8 so that each electrical contact 2 contacts and conducts with the corresponding connection tab 9, thereby making the assembly more convenient.

[0063] The preparation process of the lamp bead is as Figure 6 shown. First, each electrical contact 2 is soldered to the corresponding connection end of the lamp bead 3 by the SMD method. Then, a waterproof colloid 4 is formed by dispensing and encapsulating around the lamp bead 3. After that, the lamp bead 3 is placed into the mounting hole 51 of the glue core 5 from bottom to top, so that each electrical contact 2 passes through the corresponding through hole 52 of the glue core 5. Then, each electrical contact 2 is bent towards the outside of the through hole 52 and the outer wall of the glue core 5. Then, the tail ends of the electrical contacts 2 are kept in contact with the outer wall of the glue core 5. After that, the lamp housing 1 is inserted into the mounting hole 51 of the glue core 5 to complete the preparation process of the LED bulb 200.

[0064] In summary, compared with the prior art, the new structure of the bulb 200 can make the assembly process simple and the preparation cost low.

[0065] As Figure 9As shown, in this embodiment, the rubber core 5 has a limiting and stopping portion 53. The limiting and stopping portion 53 passes through the mounting hole 51 from the lamp bead 3 and extends vertically towards the through hole 52. The limiting and stopping portion 53 and the rubber core 5 are of an integral structure. The waterproof colloid 4 is coated around the lamp bead 3 and abuts against the lower surface of the limiting and stopping portion 53. By adding the limiting and stopping portion 53, when the lamp bead 3 is installed in the mounting hole 51 of the rubber core 5, the limiting and stopping portion 53 can block and limit the lamp bead 3, making the assembly more convenient.

[0066] As Figure 2 , Figure 5 , Figure 8 , Figure 9 and Figures 14 - 29 As shown, one end of the lamp housing 1 facing the mounting hole 51 is provided with a clamping portion 11; the clamping portion 11 of the lamp housing 1 is embedded in the mounting hole 51, and the outer wall of the clamping portion 11 is stuck in the mounting hole 51 more stably and reliably, having better sealing performance and waterproof performance. By adding the clamping portion 11, the plug-in connection between the lamp housing 1 and the rubber core 5 is more stable and reliable, and the sealing performance and waterproof performance are also better.

[0067] As Figures 1 - 5 As shown, a shoulder 54 is provided on the outer wall of the rubber core 5. By adding the shoulder 54, during the process of inserting the rubber core 5 into the lamp socket 8, the shoulder 54 can limit the insertion position to ensure that the rubber core 5 can be accurately inserted into the lamp socket 8.

[0068] As Figures 7 - 11 As shown, a string light 100 is provided, including a bulb 200, a lamp socket 8, and a power cord 6.

[0069] As Figures 6 - 7 As shown, the lamp socket 8 is sequentially installed on the power cord 6. A bulb is installed on one side of each lamp socket 8, and a wire groove 82 is provided on the other side. The wire groove 82 faces the power cord 6. The lamp socket 8 has a jack 81 that opens towards the bulb 200 and communicates with the wire groove 82.

[0070] The jack 81 has an opening 84, and at least a part of the bulb 200 enters the jack 81 through the opening 84 and is installed on the lamp socket 8.

[0071] The power cord 6 passes through the wire groove 82 and extends into the jack 81 of the lamp socket 8, and is respectively electrically connected to the corresponding terminal piece 9 in the jack 81; during the process of installing the bulb 200 onto the lamp socket 8, each terminal piece 9 is pressed by the lamp socket 8, so that each electrical contact 2 contacts and is electrically conducted with the corresponding terminal piece 9; by adding the wire groove 82, the power cord 6 passes through the wire groove 82 and the lamp socket 8 and is electrically connected to the bulb 200, thereby effectively improving the stability and reliability of the connection between the lamp socket 8 and the power cord 6.

[0072] On the inner wall of the jack 81, there are slot grooves 83 corresponding to each connection piece 9, and each connection piece 9 is arranged and clamped in the corresponding slot groove 83; during the assembly process of the connection piece 9, each connection piece 9 is embedded and limited in the corresponding slot groove 83, so that each connection piece 9 is accurately positioned and installed.

[0073] The string of lights 100 further includes a waterproof housing 12, and the waterproof housing 12 has an opening facing the lamp socket 8 for accommodating the lamp socket 8.

[0074] The string of lights 100 further includes a blocking member 10, and the blocking member 10 is located in the space between the waterproof housing 12 and the light bulb 200. The blocking member 10 seals the part of the wire slot 82 on the peripheral side of the power cord 6.

[0075] As Figure 12 shown, in an example of the blocking member 10, the blocking member 10 is a block, which is installed on the rubber core 5 in the lamp socket 8 and has a first convex block 101. The convex block is located on the side of the block facing the wire slot 82, and its shape matches the shape of the wire slot 82. The first convex block 101 is embedded in the wire slot 82, so as to enclose and seal the part of the wire slot 82 surrounding the power cord 6.

[0076] In this example, the block has two opposite side walls respectively located on both sides of the first convex block 101, and the lamp socket 8 also has two opposite inner walls respectively facing the two opposite side walls of the block. Card slots are respectively arranged on the two inner walls of the lamp socket 8, and second convex blocks 102 are respectively arranged on the two opposite side walls of the block. The second convex blocks 102 are embedded in the card slots on the inner wall of the lamp socket 8, so that the block is fixed in the lamp socket 8.

[0077] As Figure 13 shown, in another example of the blocking member 10, the blocking member 10 is an elastically openable plate, which is integrally arranged on the lamp socket 8 to enclose and seal the part of the wire slot 82 surrounding the power cord 6.

[0078] The power cord 6 includes a male connector 71 connected to one end of the power cord 6 and a female connector 72 connected to the other end of the power cord 6 for connecting to a power source; it can be understood that in some embodiments, the power cord 6 only includes a connector for connecting to a power source.

[0079] It can be understood that in some embodiments, any one of the power cord 6 and the connector can be removed to simplify the structure.

[0080] As Figures 14 - 29 shown, the shape of the lamp housing 1 can adopt different shapes and textures according to needs, such as cylindrical, spherical, pear-shaped, peach-shaped, etc., but not limited thereto.

[0081] Due to the waterproof housing of the sealed lamp holder and the blocking member for preventing glue leakage, it is possible to prevent water while avoiding the problem of glue leakage of the bulb, thereby improving the stability and yield of the product.

[0082] In the description of this embodiment, unless otherwise specified, "a plurality of" means two or more. The above content is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
