Description

Technical Field

[0001] This utility model belongs to the technical field of fishing aid equipment, specifically relating to an underwater fish-attracting lamp. Background Technology

[0002] With the development of modern fisheries technology, underwater fish-attracting lights, as an important fishing aid, are widely used in marine fishing, deep-sea aquaculture, and light-attracting operations. They attract phototactic fish using specific wavelengths of light, significantly improving fishing efficiency. However, due to their long-term operation in harsh environments with high humidity, high salt spray, and even deep-sea high pressure, underwater fish-attracting lights require extremely high waterproof and sealing performance.

[0003] Most underwater lights on the market currently use O-rings and screws to seal the light body and end cap. Some products also apply sealant to the seams to enhance waterproofing.

[0004] However, such traditional structures have many drawbacks: on the one hand, relying solely on elastic sealing rings is difficult to resist water pressure penetration in the long term, especially under conditions of greater depth or frequent temperature changes, they are prone to aging and deformation, leading to seal failure; on the other hand, sealant is mostly applied by hand, making it difficult to ensure uniform filling, no air bubbles, and no leaks, and lacking an effective guiding path, resulting in uneven distribution of the adhesive, forming local weak points, which seriously affects the waterproof reliability of the entire lamp. Utility Model Content

[0005] This invention addresses the aforementioned problems in the existing technology by proposing an underwater fish-attracting lamp with improved sealing performance.

[0006] This utility model can be achieved through the following technical solutions:

[0007] An underwater fish-attracting light, comprising:

[0008] The main body of the fish-attracting lamp includes a lamp tube assembly, an upper mounting plate, and a lower mounting plate. The lamp tube assembly includes a lamp tube cover and a lamp tube light source module housed within the lamp tube cover. The upper mounting plate and the lower mounting plate are respectively connected to the two end faces of the lamp tube assembly.

[0009] The upper mounting plate and the lower mounting plate have the same end face structure for connecting to the lamp housing assembly, and include a first mounting groove and a second mounting groove arranged at intervals from the outside to the inside. The end of the lamp housing is embedded in the first mounting groove.

[0010] The outer periphery of the first mounting groove is formed with a first protrusion, and the first protrusion is provided with an injection hole;

[0011] A second protrusion is formed between the first mounting groove and the second mounting groove, and the second protrusion has an adhesive outlet hole;

[0012] The injection hole and the dispensing hole are connected by an internal channel of the upper mounting plate or the lower mounting plate, and the dispensing hole is connected to the first mounting groove and the second mounting groove. The sealant injected from the injection hole is discharged from the dispensing hole through the internal channel to simultaneously fill and seal the areas where the first mounting groove and the second mounting groove are located.

[0013] As a further improvement of this utility model, a first sealing ring and a second sealing ring are respectively provided in the first mounting groove and the second mounting groove, and the first sealing ring and the second sealing ring are respectively provided with a first sealing groove and a second sealing groove.

[0014] As a further improvement of this utility model, the adhesive outlet is provided on the top surface of the second protrusion, and the sealant flows into the first sealing groove and the second sealing groove along the top surface of the second protrusion.

[0015] As a further improvement of this utility model, a distance is left between the lamp light source module and the lamp cover to form an airflow channel for heat dissipation and sealing detection, and a first air hole and a second air hole are respectively opened on the end face of the upper mounting plate and the lower mounting plate away from the lamp assembly, and the first air hole and the second air hole are respectively connected to the airflow channel.

[0016] As a further improvement of this utility model, the first vent and the second vent are configured as follows:

[0017] When one of them is closed, gas can be injected through the other vent to check the seal.

[0018] When both are open, gas can be injected through them to expel and replace the air in the airflow channel.

[0019] As a further improvement of this utility model, the upper mounting plate is also provided with a wire receiving groove on the end face away from the lamp tube assembly. The wire receiving groove is used to accommodate wires and is sealed with sealant.

[0020] As a further improvement of this utility model, a hanging rope mounting seat is installed on the end face of the upper mounting plate away from the lamp tube assembly, and a bottom base is installed on the end face of the lower mounting plate away from the lamp tube assembly.

[0021] As a further improvement of this utility model, the bottom base has a cavity for accommodating a bottom light source, wherein,

[0022] The receiving cavity includes an inner mounting groove and an outer mounting groove, and the outer mounting groove and the inner mounting groove are connected and transitioned by a stepped surface;

[0023] The bottom light source includes a bottom light source module and a bottom light source protective glass. The bottom light source module is disposed in the inner mounting groove, and the bottom light source protective glass is mounted on the outer mounting groove.

[0024] As a further improvement of this utility model, the bottom base has a recessed snap-fit ​​groove on the inner side wall of the outer mounting groove. When the bottom light source protective glass is installed in the outer mounting groove, there is a distance between the side wall of the bottom light source protective glass and the inner side wall of the bottom base to form an injection space. The snap-fit ​​groove and the injection space are connected to form a common injection area.

[0025] As a further improvement of this utility model, it also includes a power distribution box, the two ends of which are respectively connected to the suspension rope mounting base and the external power supply through a first cable and a second cable, and the first cable, the second cable and the power distribution box can be detachably connected.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Achieve double-sided, double-layer composite sealing, significantly improving waterproof reliability: Through the synchronous glue injection sealing of the first and second mounting grooves, combined with the flow guiding structure of "glue injection hole - internal channel - glue outlet hole", a double-sided sealing barrier is formed, effectively isolating the external water environment and preventing water from entering the light source cavity from any direction, significantly improving the long-term waterproof performance of the lamp in deep water and high-pressure environments.

[0028] 2. The injection process is controllable, the filling is uniform, and the process is highly repeatable: The sealant is injected from the injection hole, discharged from the outlet hole through the internal channel, and flows naturally, achieving orderly "one in, one out" potting and avoiding air bubble residue and uneven filling; the outlet hole is located on the top surface of the second protrusion, which further optimizes the adhesive diffusion path, ensures that the sealing area is fully, continuously, and without dead corners, and improves production consistency and automation potential.

[0029] 3. Elastic sealing and rigid sealing work together to build a multi-layer protection system: A double-layer sealing ring with a sealing groove is set in the installation groove to form a composite sealing structure of "pre-sealing + main injection". This not only prevents the glue from leaking during the injection process, but also avoids stress damage caused by rigid contact through elastic buffering, which significantly enhances the sealing durability and vibration resistance.

[0030] 4. The airflow channel and dual-pore design enable intelligent sealing management that is "detectable, drainable, and preventable": The airflow channel connects the dual pores, allowing for bubble-based sealing tests in water to directly identify leak points; at the same time, helium can be injected to replace the internal air, utilizing helium's excellent thermal conductivity to improve heat dissipation efficiency and prevent condensation and oxidation corrosion, thus comprehensively improving the environmental adaptability and lifespan of the lamp.

[0031] 5. Modular power supply, balancing economy and functionality: The distribution box connects to the detachable first and second cables, allowing users to reuse existing long cables, reducing purchase costs, and facilitating the replacement of vulnerable cables, thus improving maintenance convenience.

[0032] 6. Achieve multi-angle three-dimensional lighting and significantly improve fish attraction efficiency: By integrating an independent bottom light source into the base, the fish attraction lamp not only has circumferential light emission from the lamp tube assembly, but also achieves downward directional supplementary lighting, forming a composite light field distribution of "horizontal diffusion + vertical penetration". This design effectively expands the lighting coverage and light penetration depth of the water area below, and is especially suitable for attracting fish that swim towards light from the seabed or diagonally below (such as bottom fish, shrimp, etc.), breaking the blind spots of traditional fish attraction lamps and greatly improving the attraction effect and the targeting and efficiency of fishing operations.

[0033] 7. The bottom light source area achieves a three-level integrated seal: mechanical locking, adhesive anchoring, and surface encapsulation. By setting a snap-fit ​​groove on the inner side wall of the outer mounting groove, and forming a common injection area connected with the gap of the bottom light source protective glass side wall, the sealant is fully filled and cured. After injection, the sealant not only seals the gap between the lampshade and the base, but also forms a "glue nail" structure in the snap-fit ​​groove, producing a mechanical anchoring effect and enhancing pull-out resistance and vibration resistance. At the same time, the "pre-bonding + main injection" process prevents sealant leakage and extends the sealant to the root of the outer surface of the lampshade to form a continuous coating layer (outer edge sealing), constructing a complete sealing barrier. This design deeply integrates mechanical connection and adhesive sealing, achieving full-path sealing from internal anchoring to external protection, effectively preventing water intrusion, ensuring long-term stable operation of the bottom light source under high pressure and strong water flow, and significantly improving the overall waterproof rating, safety, and service life of the lamp.

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0047] like Figures 1-6 As shown, this utility model provides an underwater fish-attracting light, comprising:

[0048] The main body of the fish-attracting lamp includes a lamp tube assembly 100, an upper mounting plate 200, and a lower mounting plate 210. The lamp tube assembly 100 includes a lamp tube cover 100 and a lamp tube light source module 110 housed in the lamp tube cover 100 (the lamp tube light source module 110 includes a mounting plate and a lamp plate disposed on the mounting plate). The upper mounting plate 200 and the lower mounting plate 210 are respectively connected to the two end faces of the lamp tube assembly 100.

[0049] The upper mounting plate 200 and the lower mounting plate 210 have the same end face structure for connecting to the lamp housing assembly 100, and include a first mounting groove and a second mounting groove arranged at intervals from the outside to the inside. The end of the lamp housing 100 is embedded in the first mounting groove.

[0050] A first protrusion 240 is formed on the outer periphery of the first mounting groove, and an injection hole 241 is provided on the first protrusion 240.

[0051] A second protrusion 250 is formed between the first mounting groove and the second mounting groove, and the second protrusion 250 has an adhesive outlet hole 251.

[0052] The injection hole 241 and the dispensing hole 251 are connected by an internal channel of the upper mounting plate 200 or the lower mounting plate 210, and the dispensing hole 251 is connected to the first mounting groove and the second mounting groove. The sealant injected from the injection hole 241 is discharged from the dispensing hole 251 through the internal channel to simultaneously fill and seal the areas where the first mounting groove and the second mounting groove are located.

[0053] The specific glue injection process is explained as follows:

[0054] After assembling the lampshade 100 with the upper and lower mounting plates 210, the sealant is injected through the injection hole 241. The sealant first enters the channel in the first protrusion 240 and flows along the internal channel toward the outlet hole 251. Since the outlet hole 251 is located in the second protrusion 250 and is connected to the first and second mounting grooves, the sealant will naturally diffuse inward and outward simultaneously after being discharged from the outlet hole 251 under pressure, gradually filling the area of ​​the first and second mounting grooves and naturally leveling it. After the sealant has been left to stand for a period of time, it will naturally cure, thus completing the potting operation of the entire sealing area.

[0055] Once the first and second mounting slots are sealed, the sealing between the lamp tube and the first mounting slot, as well as the sealing between the mounting plate in the lamp tube assembly 100 and the second mounting slot, are completed. This establishes reliable sealing interfaces on both the front and rear sides of the lamp plate (i.e., the area where the light source module is located) inside the lamp tube assembly 100. This double-sided sealing structure completely isolates the internal cavity where the light source module is located from the external water environment, forming a double protective barrier that effectively blocks the path of water intrusion into the core electronic components from any direction.

[0056] Compared to existing technologies, this injection method has at least the following advantages:

[0057] 1. Achieve double-sided, double-layer sealing protection: By simultaneously injecting adhesive into the first and second mounting slots, a double-sided sealing barrier is constructed for the area where the lamp light source module 110 is located, effectively isolating the external water environment and significantly improving the waterproof reliability of the lamp under deep water and high pressure conditions.

[0058] 2. Controllable and uniform filling process: The flow-guiding structure of injection hole 241 - internal channel - outlet hole 251 forms a clear sealant flow path, realizing orderly potting from one end to the other, avoiding problems such as uneven manual application and air bubbles. After the sealant flows and cures naturally, it can ensure that the sealant fully, continuously and without dead corners fills the key sealing area.

[0059] 3. Improve structural integrity and durability: After the sealant cures, it firmly combines the lamp tube cover 100, the mounting plate and the sealing groove structure, which enhances the mechanical strength and vibration resistance of the connection parts, while buffering the stress changes caused by thermal expansion and contraction, and extending the service life of the lamp in complex underwater environments.

[0060] Preferably, a first sealing ring 220 and a second sealing ring 230 are respectively provided in the first mounting groove and the second mounting groove. The first sealing ring 220 and the second sealing ring 230 are respectively provided with a first sealing groove and a second sealing groove. It is worth mentioning that the setting of the first sealing ring 220 and the second sealing ring 230 makes the lamp cover and the mounting plate form an elastic compression seal. The sealing ring is subjected to axial compression during assembly, generating a uniform rebound force, ensuring that the lamp cover and the sealing groove maintain a continuous pre-tight contact, effectively preventing the seal from loosening due to vibration, temperature change or mechanical impact. This structure forms a preliminary sealing barrier before the glue is injected, which can prevent the sealant from leaking into the non-target area inside during the glue injection process, and at the same time provides "double protection" for subsequent glue sealing.

[0061] In other words, by setting up a double-layer elastic sealing ring, pre-sealing is achieved not only before the adhesive is injected, but also after the adhesive is injected and cured, it forms a composite sealing system of "elastic seal + rigid seal" together with the sealant, which significantly improves the overall waterproof level and long-term stability.

[0062] Meanwhile, the elastic buffering effect of the sealing ring avoids rigid contact between the lamp cover 100 and the metal mounting plate, effectively reducing the risk of stress concentration and crack propagation caused by differences in the thermal expansion coefficients of materials or external impacts, protecting the structural integrity of the lamp cover, and extending the service life of the lamp in complex underwater environments.

[0063] Preferably, the dispensing hole 251 is located on the top surface of the second protrusion 250, so that after the sealant is discharged from the dispensing hole 251, it can naturally spread to both sides along the top surface of the second protrusion 250 under the action of thrust and gravity, and can flow more smoothly and evenly into the area where the first sealing groove and the second sealing groove are located, ensuring that the mating interface is fully wrapped and filled by the sealant, and avoiding local lack of sealant or the formation of air gaps.

[0064] This layout optimizes the flow path of the sealant, utilizing the planar expansion characteristics of the top surface to achieve natural leveling and full coverage of the sealant. This significantly improves the filling quality of the dual sealing groove area, enhances the adhesion strength and waterproof continuity between the sealing ring and the surrounding structure, effectively prevents moisture from penetrating along the edge of the sealing ring, and further improves the overall reliability and durability of the seal.

[0065] In addition, the top surface of the second protrusion 250 is provided with an exhaust hole 252. The exhaust hole 252 is symmetrically arranged with the glue outlet hole 251, so that gas can be smoothly released from the exhaust hole 252 during the glue injection process, ensuring smooth glue injection.

[0066] Preferably, a distance is left between the lamp light source module 110 and the lamp cover 100 to form an airflow channel for heat dissipation and sealing test, and a first air hole 201 and a second air hole 211 are respectively opened on the end face of the upper mounting plate 200 and the lower mounting plate 210 away from the lamp assembly 100, and the first air hole 201 and the second air hole 211 are respectively connected to the airflow channel.

[0067] Specifically, the first vent 201 and the second vent 211 are configured as follows:

[0068] Sealing test: The lamp is completely immersed in water, and gas is injected through one of the vents. If the lamp is not properly sealed, the gas will escape from the leak point and form visible bubbles in the water, thus providing a direct assessment of the sealing performance.

[0069] To improve heat dissipation: Open both vents and introduce dry helium into the airflow channel to expel internal air and replace it with helium. After filling for a period of time, close both vents to fill the lamp with dry helium and maintain a slightly positive pressure.

[0070] Because helium has a higher thermal conductivity than air, when the lamp body is working and generating heat, the helium-filled airflow channel can more effectively transfer the heat generated by the light source module to the inner wall of the lamp barrel cover 100 through gas convection, and then exchange heat with the external water body through the lamp barrel cover 100, thereby improving the overall heat dissipation efficiency.

[0071] Overall, by setting up a first air hole 201 and a second air hole 211 connected to the airflow channel, and combining them with underwater air tightness testing methods, the sealing performance of the lamp can be verified intuitively, efficiently, and reliably under simulated actual use environment conditions. At the same time, the structure also takes into account the internal air replacement function to improve heat dissipation, realizing a multi-functional sealing design that is "inspectable, drainable, and preventable," significantly enhancing the environmental adaptability and long-term operational reliability of the underwater fish-attracting lamp.

[0072] In addition, when the first vent 201 and the second vent 211 need to be sealed, this solution adopts a triple sealing method: First, the M4 machine screw is screwed into the vent to initially seal the channel and tighten the cover; then, a small amount of sealant is injected through the gap between the screw and the vent, allowing the sealant to penetrate into the threaded joint, fill the tiny gaps, and enhance the continuity of the seal; finally, the waterproof sealing screw is tightened, and the final mechanical seal is achieved by utilizing its precise fit and the pressing action of the sealing ring and the end face.

[0073] By using a combination of "M4 machine screws + sealant injection + waterproof sealing screws" to achieve triple redundancy protection for the pore sealing area, the sealing level of this potential leakage point, the pore, is significantly improved.

[0074] This method balances operational feasibility with sealing reliability, meeting the testing requirements during production while ensuring complete pore sealing in the final use state, eliminating the risk of leakage due to vibration, pressure differential, or material aging during long-term use. It is particularly suitable for underwater fish-attracting lights in high-pressure deep-water environments, effectively ensuring a dry internal environment and electrical safety, further enhancing the overall durability and environmental adaptability of the light.

[0075] Preferably, the upper mounting plate 200 is further provided with a wire receiving groove 202 on the end face away from the lamp housing assembly 100. The wire receiving groove 202 is used to accommodate the power wires led out from inside the lamp body, and the gap between the wires and the groove wall is completely sealed by filling with sealant, which effectively avoids the risk of water seeping through the capillary between the wires and the outer shell, significantly improving the waterproof reliability of the lead wire area. Combined with the overall glue injection process, the wire sealing works synergistically with other sealing areas, further improving the omnidirectional waterproof system of the lamp, and greatly improving its safety and durability in deep water, high pressure and complex dynamic environments.

[0076] Preferably, a hanging rope mounting seat 300 is mounted on the end face of the upper mounting plate 200 away from the lamp housing assembly 100, and a bottom base 400 is mounted on the end face of the lower mounting plate 210 away from the lamp housing assembly 100.

[0077] The 300 lanyard mounting bracket is mainly used to install lanyards, enabling the fish-attracting light to be suspended and positioned during operation. It also prevents foreign objects from entering the airflow channel between the light source module and the lamp cover, avoiding blockage of the internal channel by mud, marine organisms, or net fragments, which could affect heat dissipation efficiency or gas exchange effect, thus ensuring the cleanliness of the internal environment and the stability of thermal management performance of the light fixture.

[0078] Furthermore, in this embodiment, the lanyard mounting base 300 is designed with a conical structure. This conical head design not only has a good streamlined shape, which can quickly glide through the gaps in the fishing net in the water, effectively avoiding being stuck or tangled in the net, thus improving the efficiency of deployment and retrieval, but also plays a role in breaking the water when the light is towed with the boat, reducing water resistance, reducing vibration and sway amplitude, and improving operational stability.

[0079] Meanwhile, the 300 tapered structure of the sling mount has a certain strength and guiding properties at the front end, which can slightly stretch the fishing net fibers to achieve the "self-detachment" function, further reducing the risk of getting caught in the net, and is suitable for continuous operation in complex fishing environments.

[0080] The bottom base 400 has a cavity for housing and for installing the bottom light source 500. The bottom light source 500 also enables downward directional supplemental lighting, forming a "circumferential + downward" composite lighting mode. This design can effectively expand the illumination coverage of the lamp and enhance the penetration into the water below. It is especially suitable for attracting fish that swim towards the light from the bottom or diagonally below, significantly improving fish collection efficiency and operational adaptability.

[0081] Furthermore, the receiving cavity includes an inner mounting groove 410 and an outer mounting groove 420, which are connected and transitioned by a stepped surface. Meanwhile, the bottom light source 500 includes a bottom light source module 510 and a bottom light source protective glass 520. The bottom light source module 510 is disposed in the inner mounting groove 410, and the bottom light source protective glass 520 is mounted on the outer mounting groove 420, forming a sealed fit with the bottom base 400, thereby encapsulating the bottom light source 500 entirely within the receiving cavity.

[0082] The inner mounting groove 410 and the outer mounting groove 420 are designed with stepped surfaces to achieve layered installation and precise positioning of the bottom light source module 510 and the bottom light source protective glass 520, ensuring a stable and reliable assembly process.

[0083] It is worth mentioning that in this embodiment, the bottom base 400 has a recessed snap-fit ​​groove 430 on the inner side wall of the outer mounting groove 420. When the bottom light source protective glass 520 is installed in the outer mounting groove 420, a certain gap is maintained between its side wall and the inner side wall of the bottom base 400 to form an annular glue injection space. The snap-fit ​​groove 430 and the glue injection space are connected to form a continuous common glue injection area.

[0084] Therefore, after the bottom light source protective glass 520 is assembled, sealant is injected into the injection area. The sealant can simultaneously fill the injection space and flow into the snap-fit ​​groove 430. After curing, it forms an integrated sealant structure. This design organically combines mechanical snap-fit ​​and sealant sealing, which significantly improves the connection strength and waterproof reliability of the bottom light source protective glass 520. The sealant fills the injection space, effectively sealing the gap between the bottom light source protective glass 520 and the base, preventing moisture from seeping into the interior along the mating surface.

[0085] Meanwhile, after the colloid cures deep inside the snap-fit ​​groove 430, it forms a "glue nail" effect, producing a mechanical anchoring effect, which greatly enhances the pull-out resistance and vibration resistance of the lamp cover, preventing the lamp cover from loosening due to water flow impact or external collision. In addition, the common injection area ensures that the sealant is fully filled and continuous, covering the entire connection interface without dead corners, realizing the dual functions of "structural locking + sealing protection", so that the bottom light source 500 maintains a stable and reliable sealing state during long-term underwater operation, further improving the overall safety and durability of the fish-attracting lamp.

[0086] In addition, to further improve the sealing effect, during the assembly process, a low-viscosity, fast-curing pre-adhesive is first applied to the contact area between the bottom light source protective glass 520 and the stepped surface of the outer mounting groove 420 to fix the lampshade in place and achieve the initial positioning and gap sealing of the lampshade.

[0087] This pre-bonding process can effectively seal the initial gap between the bottom light source protective glass 520 and the bottom base 400 before the formal glue injection, preventing the glue from leaking into the inner non-sealed area or creating gaps when the main sealant is injected later. After the pre-bonding glue has initially cured, the main sealant is then evenly injected into the entire common glue injection area (including the glue injection space and the snap-fit ​​groove 430) to ensure that the glue fully fills all connection interfaces.

[0088] During the sealant application process, under pressure, the sealant not only completely fills the common application area but also naturally extends outwards, covering the root area of ​​the outer surface of the bottom light source protective glass 520, forming a continuous sealing layer. This layer completely encapsulates the connection between the lampshade and the base, further extending the path for moisture intrusion and enhancing the waterproof barrier capability of the interface.

[0089] The dual-stage sealing process of "pre-bonding + main adhesive injection" significantly improves the reliability and sealing integrity of the bottom light source protective glass 520 package. The pre-bonding adhesive effectively prevents the main sealant from seeping in or filling unevenly, ensuring the controllability and consistency of the adhesive injection process.

[0090] The main sealant not only achieves the dual functions of mechanical anchoring and sealing, but its "outer edge sealing" structure extending to the outer surface of the lampshade also creates an additional waterproof barrier, greatly reducing the risk of seal cracking due to vibration, thermal cycling or external impact.

[0091] The overall structure, combined with the snap-fit ​​groove 430 and the common glue injection area, achieves three levels of protection: "mechanical locking - glue anchoring - surface encapsulation". This gives the bottom light source area 500 excellent waterproof, anti-detachment, and durability performance, making it particularly suitable for underwater fish-attracting lights that operate under high pressure and strong water flow environments for extended periods. This comprehensively improves the product's sealing level and operational reliability.

[0092] Preferably, it also includes a distribution box 600, whose two ends are connected to the sling mounting base 300 and an external power source respectively via a first cable 610 and a second cable 620, and the first cable 610 and the second cable 620 can be detachably connected to the distribution box 600.

[0093] It should be noted that the addition of the 600 distribution box and the use of a segmented cable structure were primarily for cost optimization and ease of maintenance.

[0094] On the one hand, some users already have long-distance power transmission cables that meet specifications (i.e., the second cable 620) in actual applications, which are usually tens of meters long. By setting up a detachable distribution box 600, the manufacturer only needs to provide such users with a combination configuration of the fish-attracting lamp body + the first cable 610 + the distribution box 600 when leaving the factory. The second cable 620 can be directly reused by the user, avoiding repeated purchase of long cables and significantly reducing procurement costs. The economic benefits are even more prominent in large-scale deployment scenarios.

[0095] On the other hand, due to the large length of the second cable 620, its long-term deployment in complex environments, and its high tensile strength, it is prone to wear and tear. Traditional integrated cables often require complete replacement once damaged, resulting in high maintenance costs and disruption to operations. In contrast, this solution achieves modular connection through the distribution box 600. When the second cable 620 wears out or fails, it can simply be removed from the distribution box 600 and replaced with a new cable without disassembling the main body of the light fixture or replacing the internal wiring, greatly improving maintenance efficiency and operational flexibility.

[0096] The 600 power distribution box and segmented detachable cable structure enable the modular, standardized, and scalable design of the fish-attracting lamp power supply system. This not only allows users to configure and flexibly select according to their needs, reducing initial investment costs, but also significantly improves the maintainability and economy of the equipment during long-term operation.

[0097] Currently, conventional fish-attracting lights connect the upper mounting plate 200 and the lower mounting plate 210 only through bolts 260 arranged at intervals. Although this structure can ensure the structural stability of the light fixture under normal working conditions, it lacks external protection and has poor impact and drop resistance.

[0098] When the fish-attracting lamp is accidentally dropped during transportation or placement, the lamp tube cover 110 and the bottom light source protective glass 520 are usually made of glass with excellent light transmission and weak impact resistance. They are very easy to break due to direct contact with the ground or collision, resulting in sealing failure or damage to the light source.

[0099] To address this issue, this application provides the following improvements:

[0100] Several annular plates 270 are spaced apart on the annular end faces of each bolt 260 and extend circumferentially to form a cage-like protective structure surrounding the lamp housing assembly. This cage-like structure, composed of multiple annular plates 270, is evenly distributed around the lamp housing and can preferentially contact the ground when the lamp falls, providing cushioning and support, effectively dispersing the impact force, preventing the lamp housing 110 from being directly subjected to force, and significantly improving the overall drop resistance and mechanical protection capabilities.

[0101] Meanwhile, an outwardly extending protrusion 440 is provided on the bottom end face of the base 400. The height of the protrusion 440 is greater than the outward protrusion height of the bottom light source protective glass 520, so that when the bottom of the lamp touches the ground, the protrusion 440 makes contact with the ground first, thereby extending the distance between the protective glass 520 and the ground and forming physical limiting protection. This design significantly reduces the risk of the protective glass breaking due to bottom impact, further improving the durability and safety of the lamp in actual use.

[0102] In summary, by adding a cage-shaped protective structure and a bottom protrusion, comprehensive mechanical protection for key optical components is achieved, significantly enhancing the fish-attracting lamp's resistance to drops and impacts in complex operating environments, effectively extending product lifespan, and reducing maintenance costs.
