Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0025] Example 1

[0026] like Figures 1 to 4As shown, an embodiment of the present invention preferably provides a marine constant direction mast light, which includes a rotating device 1, a lighting assembly 2 and a control component 3; one end of the rotating device 1 is connected to the ship, and the other end is connected to the lighting assembly 2; the lighting assembly 2 includes a mast light component 21, a mast light base 22 and a steel cable 23, the mast light component 21 is arranged above the mast light base 22, and a slot is provided on one end surface of the mast light base 22 close to the mast light component 21, the slot is arranged along the circumference of the mast light base 22 and extends in a direction away from the mast light component 21, the mast light component 21 is inserted into the slot, and the steel cable 23 is provided. It is arranged in the slot, and one end of the steel cable member 23 is connected to the mast light member 21, and the other end extends out of the slot; the control member 3 is arranged at one end of the rotating device 1, and the power output end of the control member 3 is connected to the end of the steel cable member 23 extending out of the slot. The control member 3 drives the steel cable member 23 to extend and retract, and the extension and retraction of the steel cable member 23 drives the mast light member 21 to rotate along the circumference of the mast light holder 22; wherein, when the rotating device 1 rotates along the circumference of the mast light holder 22, the control member 3 drives the mast light member 21 to rotate along the circumference of the mast light holder 22 and away from the rotating device 1 by pulling the steel cable member 23.

[0027] Based on the above technical features, the present invention uses a rotating device 1, which is the key to connecting the ship and the lighting assembly 2. One end of the rotating device 1 is firmly installed on the ship, and the other end is connected to the lighting assembly 2, so that the entire lighting assembly 2 can rotate relative to the ship. By setting up the lighting assembly 2, as a lighting device, it is installed above the mast lamp holder 22 to provide necessary lighting. The lighting assembly 2 includes a mast lamp 21, a mast lamp holder 22 and a steel cable 23. The mast lamp holder 22 is the base supporting the mast lamp 21. It is designed with a special slot structure. This slot is opened along the circumference of the mast lamp holder 22 and extends away from the mast lamp 21. The mast lamp 21 can be inserted into this slot and slidably connected with the slot. The mast lamp 21 can rotate circumferentially within the slot. Meanwhile, the steel cable 23 is a key component connecting the masthead light 21 and the control unit 3. Set within the slot, the cable 23 has one end connected to the masthead light 21 and the other end extending through the slot to the outside and connected to the control unit 3. When the rotating device 1 rotates along the circumference of the masthead light base 22, the control unit 3 pulls the cable 23 accordingly via the control unit 3. This pulling action causes the masthead light 21 to rotate along the circumference of the masthead light base 22, but in a direction away from the rotating device 1. This design ensures that regardless of how the rotating device 1 rotates, the masthead light 21 maintains a constant lighting direction through the precise control of the control unit 3, which is crucial for the safety and navigation of the vessel during navigation.

[0028] As some embodiments of the present invention, Figure 2As shown, the mast light assembly 21 includes a housing 211, a lamp body 212, and a power cord 213. The housing 211 is provided with a cavity, and the lamp body 212 is disposed within the cavity. One end of the power cord 213 is connected to the middle portion of the lamp body 212, and the other end extends through the cavity to the outside of the cavity. When the rotating device 1 drives the lighting assembly 2 to rotate, the connection between the power cord 213 and the lamp body 212 is fixed, and the power cord 213 can flexibly pass through the cavity of the housing 211. Therefore, the lighting direction of the lamp body 212 can remain stable and is not affected by the rotating device 1. At the same time, the provision of the housing 211 ensures that the lamp body 212 will not be affected during the rotation of the mast light assembly 211, thereby improving the stability of the lamp body 212.

[0029] As some embodiments of the present invention, Figure 2 As shown, the masthead light 21 also includes a lampshade 214 and a light shield 215. Both are positioned within the cavity, with the lampshade 214 positioned at one end of the cavity and the light shield 215 positioned at the end of the cavity facing away from the lampshade 214. The lampshade 214 and light shield 215 play a crucial role in the masthead light 21, ensuring the effective transmission and concentration of light. The lampshade 214, through its transparent material and specific shape, guides light from the lamp body 212 and diffuses it into the intended illumination area. The light shield 215 further enhances the lighting efficiency and effectiveness of the masthead light 21 by preventing unwanted light leakage.

[0030] As some embodiments of the present invention, Figure 3 As shown, the masthead light assembly 21 also includes a ball bearing 216 disposed on one end surface of the masthead light assembly 21 near the retaining groove. Multiple balls 216 are provided, extending circumferentially along the masthead light holder 22. The inclusion of multiple balls 216 not only reduces friction and wear between the masthead light assembly 21 and the holder 22 but also improves the rotational efficiency and stability of the masthead light assembly 21. These advantages collectively ensure efficient and reliable rotation of the masthead light assembly 21 in a marine constant-bearing masthead light system.

[0031] As some embodiments of the present invention, Figure 1 As shown, the masthead light base 22 also includes a fixing rod 221, one end of which is connected to the masthead light base 22 and the other end to the rotating device 1. The provision of the fixing rod 221 further enhances the stability and reliability of the marine constant-direction masthead light. It ensures the stability and accuracy of the lighting assembly 2 during rotation, providing strong support for the safe navigation of the vessel.

[0032] As some embodiments of the present invention, Figure 1 As shown, the masthead lamp holder 22 also includes fixed guide wheels 222, which are disposed at both ends of the fixing rod 221 along the length of the fixing rod 221. One end of the steel cable 23 passes through the slot and extends along the length of the fixing rod 221. Both fixed guide wheels 222 are connected to the steel cable 23 to secure the cable 23. The provision of the fixed guide wheels 222 further enhances the stability and reliability of the masthead lamp holder 22. When the control unit 3 issues a command to extend the steel cable 23, the cable 23 extends along the predetermined path guided by the fixed guide wheels 222, driving the lighting assembly 2 to rotate to a predetermined position. The fixed guide wheels 222 provide stable support and guidance, effectively ensuring the stability of the masthead lamp 21 during rotation.

[0033] As some embodiments of the present invention, Figure 4 As shown, the mast light holder 22 also includes a return spring 223. The return spring 223 is located in the slot, and the power output end of the return spring 223 is connected to the mast light 21. When the mast light 21 is subjected to a force that rotates along the circumference of the mast light holder 22, the mast light 21 drives the return spring 223 to stretch. After stretching, the return spring 223 applies an elastic force to the mast light 21 to return it to its initial position. The main function of the return spring 223 is to provide an automatic reset function. When the mast light 21 begins to rotate from its initial position due to an external force, the return spring 223 uses its elastic potential energy to apply a reverse elastic force to the mast light 21. When the external force is removed from the mast light 21, the return spring enables it to quickly and accurately return to its initial position. This function is crucial to maintaining the stability and accuracy of the mast light 21 lighting.

[0034] As some embodiments of the present invention, Figure 2 As shown, the return spring member 223 further includes a latch 224. One end of the latch 224 is connected to the end of the return spring member 223 facing away from the mast light member 21, and the other end is connected to the inner wall of the slot. The main function of the latch 224 is to secure the return spring member 223 within the slot, preventing it from moving or falling out. By connecting one end of the latch 224 to the return spring member 223 and the other end to the inner wall of the slot, the return spring member 223 can maintain a stable position and shape when subjected to external forces.

[0035] Example 2

[0036] like Figure 5 As shown, the present invention further provides a constant direction mast light for a ship, which differs from the first embodiment in that: a control part 3.

[0037] In this embodiment, a marine constant direction mast light includes a rotating device 1, a lighting assembly 2, and a driving assembly 4. The driving assembly 4 is arranged at one end of the lighting assembly 2. The driving assembly 4 includes a driving motor 41, a gear member 42, and a waterproof cover 43. The gear member 42 is arranged in a slot, and one end of the gear member 42 is connected to the lighting assembly 2, and the other end is connected to the power output end of the driving motor 41. The driving motor 41 drives the gear member 42 to rotate, and the gear member 42 drives the lighting assembly 2 to rotate along the circumference of the mast lamp holder 22.

[0038] Furthermore, a storage cavity is provided inside the waterproof cover 43, and the drive motor 41 is located in the storage cavity, thereby achieving watertight protection for the drive component 4 and ensuring that the drive motor 41 operates normally in rainy and snowy weather.

[0039] Example 3

[0040] like Figure 6 As shown, the present invention also provides a marine constant direction mast light, which is different from the first embodiment in that: the control part 3

[0041] In this embodiment, a constant-direction masthead light for ships comprises a rotating device 1, an illumination assembly 2, a laser capture device 5, and a laser emitting device 6. The laser emitting device 6 is mounted high on the bow of the ship, facing the illumination assembly 2, allowing the laser to illuminate the laser capture device 5 without obstruction. After capturing the laser signal, the laser capture device 5 maintains its orientation facing the emitting device. Once the rotating device 1 rotates, the laser capture device 5 automatically captures the light source, driving the masthead light assembly 21 to rotate, maintaining the constant direction of illumination from the masthead light assembly 21.

[0042] In summary, the embodiment of the present invention provides a marine constant direction mast light, which has the following advantages compared with the prior art: 1) Rotating device 1, which is the key to connecting the ship and the lighting assembly 2. One end of the rotating device 1 is firmly mounted on the ship, and the other end is connected to the lighting assembly 2, so that the entire lighting assembly 2 can rotate relative to the ship; 2) The lighting assembly 2, which is mainly a lighting device, is installed above the mast light holder 22 to provide necessary lighting. The lighting assembly 2 includes a mast light component 21, a mast light holder 22, and a steel cable 23. The mast light holder 22 is the base supporting the mast light component 21. It is designed with a special slot structure. This slot is opened along the circumference of the mast light holder 22 and extends away from the mast light component 21. The mast light component 21 can be inserted into this slot and slidably connected to the slot. The mast light component 21 can rotate circumferentially in the slot. At the same time, the steel cable 23 is a key component connecting the mast light 21 and the control part 3. The steel cable 23 is set in the slot, one end of which is connected to the mast light 21, and the other end extends through the slot to the outside and is connected to the control part 3; 3) Control part 3, when the rotating device 1 rotates along the circumference of the mast light holder 22, the control part 3 will pull the steel cable 23 accordingly. This pulling action will cause the mast light 21 to rotate along the circumference of the mast light holder 22, but the direction of rotation is away from the rotating device 1. This design ensures that no matter how the rotating device 1 rotates, the mast light 21 can maintain a constant lighting direction through the precise control of the control part 3, which is crucial for the safety and navigation of the ship during navigation. The present invention effectively solves the problem in the prior art that the ship mast light 21 is generally unable to be installed on the rotating device 1 of the ship, resulting in a high investment cost of the ship mast light 21, a large deck area occupied, and an impact on ship operations.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
