Specific embodiments

[0049] The present utility model will be described below in conjunction with specific embodiments.

[0050] Embodiment 1, as Figures 1 to 3b shown, a string light 100 includes a lamp head 1, a lamp tube 2 and a lampshade 3. The lamp head 1 includes an inner shell part 101 for connecting the lamp tube 2 and an outer shell part 102 for connecting the lampshade 3. A connection structure 104 is provided in the first area 103 between the inner shell part 101 and the outer shell part 102. The connection structure 104 covers the first area 103 along the circumferential direction of the inner shell part 101, and the connection structure 104, the inner shell part 101 and the outer shell part 102 are integrally formed.

[0051] Optionally, the first area 103 is a cavity to save materials and reduce production costs.

[0052] Optionally, the connection structure 104 is an annular plate to improve the production success rate and use safety of the product. It should be understood that the connection structure 104 can also be other structures, such as an annular column, which is not limited herein.

[0053] Specifically, one side of the inner shell portion 101 facing the lamp tube 2 has a first threaded hole 105, and one side of the lamp tube 2 facing the first threaded hole 105 has a first thread 106. The lamp tube 2 is connected to the first threaded hole 105 through the first thread 106.

[0054] Specifically, one side of the outer shell portion 102 facing the lampshade 3 has a second threaded hole 107. The second threaded hole 107 is located on the side of the connecting structure 104 facing the lampshade 3. One side of the lampshade 3 facing the second threaded hole 107 has a second thread 108. The lampshade is connected to the second threaded hole 107 through the second thread 108.

[0055] From the above situations, it can be seen that through the above structural design, a connecting structure 104 is provided in the first region 103 between the inner shell portion 101 and the outer shell portion 102 of the lamp head 1 of the string lamp 100 in the first embodiment. The connecting structure 104, the inner shell portion 101, and the outer shell portion 102 are integrally formed, thereby reducing the difficulty of the manufacturing process, facilitating quick installation, having a low preparation cost, and improving production efficiency. In addition, since the connecting structure 104 covers the first region 103 along the circumferential direction of the inner shell portion 101, the connection stability between the inner shell portion 101 and the outer shell portion 102 is enhanced, and the stability of the overall structure of the string lamp 100 is enhanced.

[0056] Embodiment 2, as Figure 1 、 Figures 4a to 5b shown, a string lamp 100 includes a lamp head 1, a lamp tube 2, and a lampshade 3. The lamp head 1 includes an inner shell portion 101 for connecting the lamp tube 2 and an outer shell portion 102 for connecting the lampshade 3.

The connecting structure 104 covers the first region 103 along the circumferential direction of the inner shell portion 101. The connecting structure 104, the inner shell portion 101, and the outer shell portion 102 are integrally formed.

[0057] The difference between the second embodiment and the first embodiment is that the lamp head 1 in the second embodiment is connected to the lamp tube 2 and the lampshade 3 in the following manner. Specifically, one side of the inner shell portion 101 facing the lampshade 3 has a first threaded hole 105. One side of the lampshade 3 facing the first threaded hole 105 has a second thread 108. The lampshade 3 is connected to the first threaded hole 105 through the second thread 108, and the lamp tube 2 is fixed to the lampshade 3.

[0058] From the above situations, it can be seen that through the above structural design, fixing the lamp tube 2 to the lampshade 3 can reduce the difficulty of the manufacturing process and also facilitate the replacement of the lamp tube 2 and the lampshade 3.

[0059] Embodiment 3, as Figures 6 to 8bAs shown in the figure, the difference between the third embodiment and the first embodiment is that it does not include the lampshade 3. Specifically, a string light 100 includes a lamp head 1 and a lamp tube 2. The lamp head 1 includes an inner shell part 101 and an outer shell part 102 for connecting the lamp tube 2. A connection structure 104 is provided in a first area 103 between the inner shell part 101 and the outer shell part 102. The connection structure 104 covers the first area 103 along the circumferential direction of the inner shell part 101. The connection structure 104, the inner shell part 101 and the outer shell part 102 are integrally formed.

[0060] From the above situation, it can be seen that through the above structural design, since the lampshade 3 is not required, the manufacturing cost of the string light 100 is reduced.

[0061] Among them, the specific structure and shape of the lamp tube 2 can be set according to actual needs. For example Figure 2b and Figure 6 the different structures shown are not limited herein.

[0062] Embodiment Four, as Figures 9a to 10b shown in the figure, the difference between the fourth embodiment and the second embodiment is that the lamp tube 2 is replaced by a filament 4. Specifically, a string light 100 includes a lamp head 1, a filament 4 and a lampshade 3. The lamp head 1 includes an inner shell part 101 for connecting the lampshade 3 and an outer shell part 102 for connecting the lampshade 3. A connection structure 104 is provided in a first area 103 between the inner shell part 101 and the outer shell part 102. The connection structure 104 covers the first area 103 along the circumferential direction of the inner shell part 101. The connection structure 104, the inner shell part 101 and the outer shell part 102 are integrally formed.

[0063] One side of the inner shell part 101 facing the lampshade 3 has a first threaded hole 105, and one side of the lampshade 3 facing the first threaded hole 105 has a second thread 108. The lampshade 3 is connected to the first threaded hole 105 through the second thread 108, and the filament 4 is fixed to the lampshade 3.

[0064] From the above situation, it can be seen that through the above structural design, by replacing the lamp tube 2 with a filament 4, the requirements of various scenarios can be adapted, and the use flexibility of the string light 100 can be improved.

[0065] Embodiment Five, as Figures 1 to 10b shown in the figure, the difference between the fifth embodiment and the first embodiment is that the lamp tube 2 has a first positive part 201 and a first negative part 202. One side of the inner shell part 101 facing the first positive part 201 has a first opening 5, and one side of the inner shell part 101 facing the first negative part 202 has a second opening 6. A first metal part 501 is arranged in the first opening 5, and a second metal part 601 is arranged in the second opening 6. The first metal part 501 extends from the first opening 5 and is electrically connected to the first positive part 201, and the second metal part 601 extends from the second opening 6 and is electrically connected to the first negative part 202.
