Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a night fishing light with a replaceable optical lens module. Background Technology

[0002] As a crucial piece of equipment for outdoor fishing, the optical performance of a night fishing light directly impacts the illumination of the fishing area. Traditional products generally employ a fixed optical lens design, using only one fixed lens to achieve basic single-spot size adjustment through a single lens module. This technical architecture has significant limitations: the range of spot size adjustment is restricted by the fixed focal length structure. In scenarios requiring expanded observation range or enhanced local brightness, users can only compromise by physically moving the light fixture or sacrificing sharpness. When the spot diameter increases, the central illuminance decreases, creating an irreconcilable conflict between observation sharpness and illumination range.

[0003] In existing technologies, although some high-end products attempt to improve bokeh parameters through zoom mechanisms, they cannot directly replace the lens and cannot simultaneously adjust the size and sharpness of various bokeh spots. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a night fishing light with a replaceable optical lens module. Through structural improvements to the lens module, the head ring can be directly replaced, and the aperture ring within the head ring enables focal length adjustment, allowing for simultaneous changes in spot size and sharpness, thus enhancing ease of use. Furthermore, the replaceable lens module, employing a standardized interface, integrates optical requirements across multiple scenarios. Moreover, the aperture ring's focal length adjustment method allows for focusing operations even in a sealed, waterproof environment, combining focusing functionality with a waterproof design, and simplifying operation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings:

[0023] Lens module 2 includes head ring connecting ring 21 and head ring 22. The head ring 22 is adapted to and connected to the output aperture 12 through the head ring connecting ring 21.

[0024] The head ring 22 includes a lens 221 and an aperture ring 222. The aperture ring 222 is located at the end of the head ring 22, and the lens 221 is located inside the aperture ring 222 inside the head ring 22. The focal length is adjusted by the aperture ring 222.

[0025] In this embodiment, the improved structure of the lens module 2 allows the head ring 22 to be directly replaceable. At the same time, the aperture ring 222 inside the head ring 22 can achieve focal length adjustment, enabling simultaneous changes in spot size and sharpness, thus improving the convenience of use. Furthermore, the interchangeable lens module 2 with a standardized interface can integrate optical needs for multiple scenarios. Moreover, the focal length adjustment method of the aperture ring 222 can achieve focusing operation in a sealed and waterproof environment, compatibility with focusing operation and waterproof design, and simple operation.

[0026] Specifically, the optical lens determines the size of the light spot of the lamp. This invention improves the structure of the lens module 2, allowing for the direct replacement of a lens module 2 with the original lens 221 module and other structural elements of the night fishing lamp. This allows the light spot to be enlarged or reduced by adjusting the lens focal length, increasing the viewing area when the light spot is enlarged and reducing light spot distortion when the focal length is adjusted, thereby improving brightness and viewing clarity.

[0030] During the assembly process, after connecting the dimming ring 222 and the head ring 22, the lens 221 is inserted into the head ring 22 from the inside. Finally, the lens retaining ring 223 (with glue applied around the lens retaining ring 223) is pressed into the head ring 22 to complete the assembly of the head ring 22.

[0031] In the above embodiment, preferably, the lamp body 11 includes an upper cover 13, a middle cover 14, a tail cover 15, a battery box 16, and a switch 17. The upper cover 13 is disposed outside the light ring 12, the middle cover 14 is disposed outside the battery box 16, the battery box 16 is disposed inside the lamp body 11, the tail cover 15 is disposed outside the end of the battery box 16, and the switch 17 is disposed on the side of the lamp body 11.

[0032] like Figure 2 As shown, during the implementation process, the assembled head ring 22 is connected to the head ring connecting ring 21, and then the head ring connecting ring 21 is twisted to connect the head ring connecting ring 21 to the light output ring 12 of the night fishing lamp body 1.

[0033] If you need to change the lens, simply remove the head ring 22 from the head ring connecting ring 21, and then install the head ring 22 that you want to replace onto the head ring connecting ring 21.
