[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, a rotating wall lamp includes a lamp holder 1, a light-emitting module 2, and a hinge 3; the lamp holder 1 is provided with a stud 11, the light-emitting module 2 is provided with a rocker arm 21, and the end of the rocker arm 21 away from the light-emitting module 2 is a ball head; the hinge 3 includes a first nut 31 and a ball head seat 32 disposed in the inner cavity of the first nut 31; the first nut 31 is threadedly connected to the stud 11, and the ball head seat 32 has a hinge cavity that is hinged to the spherical surface of the ball head.

[0038] Working principle: A rocker arm 21 is added to the light-emitting module 2, and the end of the rocker arm 21 away from the light-emitting module 2 is designed as a ball head structure. The ball head is spherically hinged to the ball head seat 32 of the hinge member 3, so that the light-emitting module 2 can move with multiple degrees of freedom relative to the hinge member 3. At the same time, a stud 11 is added to the lamp holder 1, and the hinge member 3 is threadedly connected to the stud 11 through the first nut 31, so that the light-emitting module 2 is assembled on the lamp holder 1, and the light-emitting module 2 can move with multiple degrees of freedom relative to the lamp holder 1, thereby realizing the multi-directional adjustment of the lighting area of ​​the light-emitting module 2.

[0039] It is worth noting that the stud 11, rocker arm 21 and ball head seat 32 are all hollow parts. The lamp holder 1 has a threaded hole, and the stud 11 is threadedly connected to the lamp holder 1 so that the wiring harness of the light-emitting module 2 can pass through the rocker arm 21, ball head seat 32 and stud 11 in sequence to reach the inner cavity of the lamp holder 1, thereby preventing the wiring harness of the light-emitting module 2 from being exposed to the outside.

[0040] Additionally, a washer 12 is added for pressure buffering during the threaded tightening process of the stud 11 and the first nut 31. In specific implementation, the washer 12 is first pre-placed on the surface of the lamp holder 1, with its inner hole fitting around the root of the stud 11; when the first nut 31 is screwed into the stud 11 and a tightening force is applied, the washer 12 contacts the bottom surface of the first nut 31 and the outer shell of the lamp holder 1 through its upper and lower end faces respectively, converting the concentrated load into a uniform pressure, thereby preventing the first nut 31 from directly squeezing the outer shell of the lamp holder 1, which could lead to paint wear or structural deformation.

[0041] In some embodiments, the ball head seat 32 can be disposed within the first nut 31 by injection molding, by interference fit, or by threaded connection. Preferably, the ball head seat 32 is threadedly connected to the first nut 31. Threaded connection facilitates the production of the hinge 3 and the assembly of the ball head seat 32 and the first nut 31.

[0042] In some implementations, please refer to Figure 1 and Figure 5As shown, the light-emitting module 2 includes a connecting pipe 22 and a lamp tube 23. The rocker arm 21 is connected to the connecting pipe 22. The opening of the connecting pipe 22 is provided with a first terminal 221 that is electrically connected to the power drive (not shown) inside the lamp holder 1. The lamp tube 23 is provided with a second terminal 231 that is electrically connected to the first terminal 221. The lamp tube 23 is connected to the connecting pipe 22 and to the power drive and other electrical components inside the lamp holder 1 by inserting the second terminal 231 into the first terminal 221. At the same time, the rocker arm 21, which is spherically hinged to the hinge member 3, is connected to the connecting pipe 22, so that the lamp tube 23 can move with multiple degrees of freedom relative to the lamp holder 1, thereby realizing the multi-directional adjustment of the lighting area of ​​the lamp tube 23.

[0043] It is worth noting that a second nut 222 is threaded onto the outer wall of the connecting pipe 22. After the second terminal 231 is inserted into the first terminal 221, the lamp tube 23 abuts against the second nut 222. The second nut 222 is used to restrict the lamp tube 23 from getting closer to the connecting pipe 22, preventing the second terminal 231 from being over-inserted into the first terminal 221, which would damage the connection structure between the lamp tube 23 and the second terminal 231, as well as the connection structure between the connecting pipe 22 and the first terminal 221.

[0044] Additionally, the rocker arm 21 and the connecting pipe 22 can be integrally molded by injection molding, or an assembly hole can be provided on the wall of the connecting pipe 22, one end of the rocker arm 21 can be inserted into the assembly hole, and then the rocker arm 21 and the connecting pipe 22 can be welded to ensure the sealing of the connection between the rocker arm 21 and the connecting pipe 22.

[0045] In some implementations, please refer to Figure 5 As shown, a first sealing ring 4 is provided between the first terminal 221 and the connecting pipe 22. The first sealing ring 4 ensures the sealing between the first terminal 221 and the connecting pipe 22, thereby improving the dustproof and waterproof performance of the light-emitting module 2.

[0046] In some implementations, please refer to Figure 5 As shown, a second sealing ring 5 is provided between the first terminal 221 and the second terminal 231. The second sealing ring 5 ensures the sealing between the first terminal 221 and the second terminal 231, thereby improving the dustproof and waterproof performance of the light-emitting module 2.

[0047] In some embodiments, the first terminal 221 and the second terminal 231 are four-core connectors. An emergency power supply (not shown) is provided inside the lamp holder 1. The four-core connector is electrically connected to the power driver and the emergency power supply. The four-core connector of the first terminal 221 has two wires connected to the positive and negative terminals of the power driver, and the other two wires connected to the positive and negative terminals of the emergency power supply, respectively. The four-core connector of the second terminal 231 has two wires connected to the positive terminal of the light source board inside the lamp tube 23, and the other two wires connected to the negative terminal of the light source board inside the lamp tube 23. When the first terminal 221 and the second terminal 231 are connected, a conductive circuit is formed between the power driver and the light source board, as well as a conductive circuit between the emergency power supply and the light source board. Therefore, when the power driver is de-energized, the emergency power supply can be immediately activated to allow the light source board to operate normally.

[0048] In some embodiments, the first terminal block 221 includes a first terminal 2211 and a first connecting sleeve 2212 sleeved on the outer wall of the first terminal block 2211. The first connecting sleeve 2212 is connected to the connecting tube 22 by waterproof adhesive. The second terminal block 231 includes a second terminal 2311 electrically connected to the first terminal block 2211 and a second connecting sleeve 2312 sleeved on the outer wall of the second terminal block 2311. The second connecting sleeve 2312 is connected to the lamp tube 23 by waterproof adhesive. The connection of the first connecting sleeve 2212 to the connecting tube 22 by waterproof adhesive improves the dustproof and waterproof performance between the connecting tube 22 and the first connecting sleeve 2212. The connection of the second connecting sleeve 2312 to the lamp tube 23 by waterproof adhesive improves the dustproof and waterproof performance between the lamp tube 23 and the second connecting sleeve 2312, thereby improving the dustproof and waterproof performance of the light-emitting module 2.

[0049] It is worth noting that the first connecting sleeve 2212 is connected to the first terminal 2211 by waterproof adhesive, which can improve the dustproof and waterproof performance between the first connecting sleeve 2212 and the first terminal 2211; the second connecting sleeve 2312 is connected to the second terminal 2311 by waterproof adhesive, which can improve the dustproof and waterproof performance between the second connecting sleeve 2312 and the second terminal 2311, and further improve the dustproof and waterproof performance of the light-emitting module 2.

[0050] In some implementations, please refer to Figure 1 As shown, the light-emitting module 2 also includes a decorative tube 24 sleeved on the outer wall of the lamp tube 23. The decorative tube 24 can be used to control the light emitted by the lamp tube 23. Specifically, the decorative tube 24 can be a blocking component that blocks part of the light emitted by the lamp tube 23, so that the light-emitting module 2 can shine light in a specific direction or emit a specific pattern; it can also be a light filter component that filters light, so that the light-emitting module 2 can emit light of a specified color.

[0051] In some implementations, please refer to Figure 6As shown, the light-emitting module 2 also includes an end cap 25, which is disposed at the end of the decorative tube 24 away from the connecting tube 22. The end cap 25 is used to block the light beam emitted from the end of the lamp tube 23, preventing light leakage from the light-emitting module 2 and affecting its performance.

[0052] It is worth noting that if the end of the lamp tube 23 away from the connecting tube 22 is an open structure, that is, the light source board inside the lamp tube 23 can be directly seen from that point, then the end cap 25 is provided with a sealing block 252 that can extend into the inner cavity of the lamp tube 23. At the same time, the sealing block 252 is connected to the inner wall of the lamp tube 23 by waterproof glue, and the end cap 25 is connected to the decorative tube 24 by waterproof glue to prevent water and dust from entering the lamp tube 23 from the end cap 25.

[0053] In some implementations, please refer to Figure 6 and Figure 7 As shown, the decorative tube 24 has a positioning groove 241 at the end away from the connecting tube 22, and the end cap 25 has a positioning head 251 that matches the positioning groove 241. By inserting the positioning head 251 into the positioning groove 241, the end cap 25 can be quickly installed on the decorative tube 24.

[0054] In some implementations, please refer to Figure 2 and Figure 8 As shown, the rotating wall lamp also includes a mounting plate 6, which has mounting holes 61 and hooks 62. The bottom of the lamp holder 1 has a hanging ear 13 that matches the hook 62. During wall mounting, the mounting plate 6 passes through the mounting holes 61 with expansion bolts. Then, by operating the lamp holder 1, the hanging ear 13 of the lamp holder 1 is hooked onto the hook 62 of the mounting plate 6, thus completing the installation of the rotating wall lamp on the wall.
