DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-3 As shown, the underwater projection light of the present invention is a lighting device for installation in an underwater environment. It includes a hollow and transparent lamp tube 01 and a light-emitting component disposed within lamp tube 01. End caps 02 are disposed at both ends of lamp tube 01. Each end cap 02 is provided with a connecting component. One end of the connecting component is located within end cap 02 and electrically connected to the light-emitting component, while the other end of the connecting component is located outside end cap 02. During use, an external power source is electrically connected to the connecting component, thereby activating the light-emitting component within lamp tube 01, and the light generated by the light-emitting component passes through lamp tube 01. Because connecting components are disposed at both ends of lamp tube 01, in actual use, the light-emitting component can be activated by connecting either connecting component to an external power source. This improves installation practicality.

[0023] The connection assembly includes a fixing post 03 fixedly connected to the end cap 02 and a threaded post 04 fixedly connected to fixing post 03. A transition hole 05 and a connection hole 06 are coaxially located at the center of fixing post 03. The diameter of connection hole 06 is smaller than that of transition hole 05. One end of threaded post 04 is fixedly mounted in connection hole 06, while the other end extends out of end cap 02, away from the lamp tube 01, for connection to an external power source. Transition hole 05 is connected to lamp tube 01. A mounting hole 07 is located in the center of end cap 02, which mates with fixing post 03. One end of fixing post 03 is fixedly mounted in mounting hole 07, flush with end cap 02, while the other end of fixing post 03 extends toward lamp tube 01 and penetrates it. It should be noted that fixing post 03 and end cap 02 are fixedly connected by welding, integral molding, or transition fit. The connection assembly, end cap 02, and the connection assembly itself are typically waterproofed to IP65 or higher, capable of withstanding a certain level of water pressure.

[0024] To further improve the sealing performance, a first retaining ring 08 is provided on the outer circumferential surface of the fixing column 03. The first retaining ring 08 and the fixing column 03 are integrally formed. The diameter of the first retaining ring 08 is adapted to the inner diameter of the end cap 02. A sealing groove 09 is provided on one side of the first retaining ring 08, and a first silicone pad 10 is provided on the other side of the first retaining ring 08. One side of the first silicone pad 10 abuts against the first retaining ring 08, and the other side abuts against the end of the lamp tube 01. A sealing ring is provided in the sealing groove 09, and the sealing ring abuts against the end cap 02. The provision of the first silicone pad 10 and the sealing ring improves the sealing performance between the fixing column 03 and the end cap 02, thereby further improving the waterproof performance of the end cap 02. At the same time, the first silicone pad 10 can also improve the fire resistance between the lamp tube 01 and the end cap 02.

[0025] A second retaining ring 11 is integrally formed on the outer circumferential surface of the threaded column 04. The second retaining ring 11 is located within the transition hole 05 and abuts the bottom surface of the transition hole 05, with sealant provided between the two. An external thread 12 is provided on the outer surface of the threaded column 04, and a fixing nut 13 is threadedly connected to the threaded column 04. The fixing nut 13 is located outside the fixed column 03 and abuts the end surface of the fixed column 03. By screwing the fixing nut 13, the first retaining ring 08 abuts the bottom surface of the transition hole 05, and sealant is provided between the first retaining ring 08 and the bottom surface of the transition hole 05. This not only achieves a fixed connection between the threaded column 04 and the fixed column 03, but also improves the sealing between the fixed column 03 and the threaded column 04.

[0026] To prevent the fixing nut 13 from loosening during long-term use, a washer 14 is provided between the fixing thread and the fixing column 03. The washer 14 abuts against the end surface of the fixing column 03. The washer 14 can prevent the fixing nut 13 from loosening.

[0027] A connecting strap 15 is provided between the washer 14 and the fixing nut 13. The end of the connecting strap 15 is connected to a sealing cap 16, which has internal threads that mate with the external threads 12. When not in use, the sealing cap 16 is threadedly connected to the threaded post 04 to prevent water from entering the insertion hole 17 and damaging the conductive post 19.

[0028] Threaded post 04 is penetrated by a through-hole 17, which is equipped with a mounting plate 18. Mounting plate 18 is equipped with several conductive posts 19. One end of each conductive post 19 extends through mounting plate 18 into transition hole 05, and the other end is located within through-hole 17. The conductive posts 19 within transition hole 05 are electrically connected to the light-emitting assembly. The conductive posts 19 within through-hole 17 and the threads on the outer surface of threaded post 04 form a female power connector. A male power connector is then electrically connected to an external power source, thereby establishing an electrical connection between the external power source and the conductive posts 19.

[0029] Since one end of the fixing post 03 is inserted into the lamp tube 01, a third silicone pad 20 is provided between the fixing post 03 and the light-emitting component. One end of the third silicone pad 20 abuts the fixing post 03, and the other end abuts the light-emitting component, further improving the sealing between the light-emitting component and the lamp tube 01.

[0030] The light-emitting assembly includes a light source holder 21 and a cover plate 22, fixedly mounted at intervals within the lamp tube 01. A light board 23 is fixedly mounted on the light source holder 21. Several light sources 24 are fixedly mounted on the light board 23. The cover plate 22 is provided with a stabilizing hole 25 adapted for the light source 24 and a light exit hole 26 coaxially arranged with the stabilizing hole 25. The top of the light source 24 is located within the stabilizing hole 25.

[0031] See also Figure 2 As shown, the underwater projector also includes a mounting bracket, which includes an upper bracket 27 that fits over the end cap 02 and a lower bracket 28 that is rotatably connected to the upper bracket 27. A fastener is threaded onto the upper bracket 27, and the end of the fastener abuts the end cap 02. A lower connecting section 29 is integrally formed at the bottom of the lower bracket 28, and a fixing nut 13 is fixedly mounted within the lower connecting section 29. A locking hole 30 is fixedly provided on the lower bracket 28, and a fastener is disposed within the locking hole 30, which is threadably connected to the fixing nut 13. When the fastener is loosened, the upper bracket 27 can rotate around the fastener in the locking hole 30. A mounting plate 18 is also provided at the bottom of the lower bracket 28.

[0032] See also Figure 3As shown, another embodiment of the mounting bracket differs from the above mounting bracket in that the mounting bracket includes a connecting plate 31 and support plates 32 arranged at both ends of the connecting plate 31. The tops of the support plates 32 are provided with receiving grooves 33. The receiving grooves 33 on the two support plates 32 form receiving holes that adapt to the lamp tube 01. A connecting rod 34 is connected between the two support plates 32. The connecting rod 34 is composed of a fastener and a fixing nut 13. A support tube 35 is sleeved on the connecting rod 34 and is located between the two support plates 32.

[0033] It should be noted that for the sake of clarity, the fasteners described in this application are any one of screws, bolts, and screws, and the "fixing nuts" installed in different positions are marked with the same figure number "13".
