[0002] Marine fishery and resource development are the most important components of my country's marine industry, with huge market economic benefits. At present, my country's light-attracted fishery is developing rapidly. Fish-attracting lamps are the main fishing aids, which use the phototropism of fish to achieve high-efficiency fishing operations. Since the 1990s, fish-attracting lamps have been widely used in marine fishing operations. LED fish-attracting lamps will gradually replace metal halide lamps due to their low energy consumption, strong directionality, strong penetration and wide range of action.

[0003] With the global shortage of fishery resources and the increasing difficulty of fishing, fishermen have an increasing demand for efficient fish gathering equipment. The high-efficiency LED fish gathering and fishing aid device with dual-channel heat conduction will gradually become the first choice of fishermen due to its significant advantages, and the market demand and prospects are expected to continue to grow. The continuous advancement of LED technology, such as higher luminous efficiency, more precise spectrum control, and intelligent control, will further enhance the performance and competitiveness of high-efficiency LED fish gathering and fishing aid devices, and expand their application areas and market space. For example, through intelligent control systems, fishermen can remotely adjust the intensity, color, and irradiation angle of the light according to different fishing scenes and fish distribution. The attention paid by governments of various countries to the sustainable development of fisheries, as well as the promotion and support policies for environmentally friendly and energy-saving fishery equipment, will provide strong policy guarantees and financial support for the market development of high-efficiency LED fish gathering and fishing aid devices. Compared with traditional fish gathering equipment such as metal halide lamps, LED fish gathering lamps have obvious advantages. As fishermen's understanding of LED fish gathering lamps continues to deepen and the technology continues to mature, the high-efficiency LED fish gathering and fishing aid device with dual-channel heat conduction will accelerate the replacement of traditional fish gathering equipment, and the market share will further expand. As the world's largest producer of LED fish-attracting lights, China's products are exported to all parts of the world. China's dual-channel heat-conducting, high-efficiency LED fish-attracting and fishing-aiding devices are expected to further expand the international market and increase its share of the global market.

[0004] However, a key technical problem faced by LED fish attracting devices is that LED fish attracting lamps require high power, but due to size limitations, they often have poor heat dissipation, resulting in reduced light efficiency, which reduces the life of the LED fish attracting lamps. In addition, if the use method is incorrect or not smooth on the operating fishing boat, the fishing effect does not reach the optimal efficiency with the same cost and light use. The present invention proposes a dual-channel heat conduction LED fish attracting and fishing aid device and its use method, aiming to solve the above problems. Summary of the invention

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A dual-channel heat-conducting LED fish-attracting and fishing-aiding device comprises an LED fish-attracting lamp, a switch, a rectifier, and electric wires. The LED fish-attracting lamp is provided with a high-efficiency LED lamp group. The LED fish-attracting lamps are distributed on lamp poles to achieve the fish-attracting function.

[0008] Furthermore, the LED fish-attracting lamp is divided into a flat mirror LED fish-attracting lamp and a small-angle LED fish-attracting lamp according to the different light-emitting angles of the lens. Three flat mirror LED fish-attracting lamps are installed on the small lamp pole, and each flat mirror LED fish-attracting lamp can realize the free switching between red and white light; the small-angle LED fish-attracting lamp is installed on the large lamp pole.

[0010] Furthermore, the LED fish attracting lamp includes a cooling fan, a fan connecting plate, a fixed plastic plate, a wavy heat sink, a wind shield, an anti-collision rubber strip, a wiring terminal, an aluminum frame, an LED light-emitting module, a sealing ring, an optical lens, and a stainless steel pressure plate; the cooling fan is fixed to the upper end of the fan connecting plate by a plurality of fixing screws; a fixed plastic plate is provided at the lower end of the fan connecting plate; the cooling fan, the fan connecting plate and the fixed plastic plate are fixedly connected to the wavy heat sink as a whole by a plurality of fixing screws; the lower end of the wavy heat sink is connected to the aluminum frame; the anti-collision rubber strip is fixed around the plane where the wavy heat sink of the aluminum frame is located; a wiring terminal mounting seat is provided on one side of the aluminum frame, and one side of the wiring terminal mounting seat is threadedly connected to the wiring terminal; the LED light-emitting module is installed in a groove of the aluminum frame opposite to the plane where the wavy heat sink is located by fixing screws; a stainless steel pressure plate is provided on one side of the optical lens; the optical lens and the stainless steel pressure plate are fixed to the back mounting surface of the aluminum frame by fixing screws, and the aluminum frame adopts ADC12 type die-cast aluminum alloy.

[0011] Furthermore, the dual-channel heat-conducting LED fish-attracting and fishing-aiding device includes a dual-channel heat-conducting structure, which includes a passive heat dissipation structure and an active heat dissipation structure. The passive heat dissipation structure includes a wavy heat sink and a wind shield. The design of the wavy heat sink can increase the heat dissipation area and improve the heat dissipation efficiency. The active heat dissipation structure is realized by a heat dissipation fan.

[0012] Furthermore, the dual-channel heat conduction structure of the LED fish collecting device, that is, the use of wavy heat sinks, wind shields, reinforcing ribs, screw holes, and top columns are formed by pressure casting; the wavy heat sink is located on the back of the aluminum frame, and the wavy heat sink is divided into two symmetrical parts by the wind shield, each part is composed of 72 wavy heat sinks of different lengths, and the angle between the two heat sinks is 5°.

[0013] Furthermore, a wind shield and reinforcing ribs are provided in the middle of the back of the aluminum frame, and the reinforcing ribs are located around the front edge of the aluminum frame. The dual-channel heat conduction structure also includes a top column, and the top column is located on the corrugated heat sink.

[0014] A method for using a dual-channel heat-conducting LED fish-attracting and fishing-aiding device comprises the following steps:

[0015] (1) Design a saury boat area division scheme, dividing the saury boat into three areas: A, B, and C. Area A is the left half, area B is the right half, and area C is the center area for the light pole net laying;

[0016] (2) During the fish gathering stage, use a sea sweeping strong light to gradually attract the fish schools in the distance to the vicinity of the boat, and then turn on the white light of the LED fish attracting light to make the saury gather around the boat;

[0017] (3) In the fish stabilization stage, when the density of fish around the hull reaches a certain level, the white light is switched to red light to reduce the range of fish activity, thus playing the role of stabilizing and gathering fish;

[0018] (4) During the fish chasing stage, when the fish school moves stably under the red light, the small red lights on the light poles are turned off from the port side of areas A and B to the big light pole on the right side of the ship, leaving only the red light of the big light pole in area C. The fish school chases the red light and gathers in area C via the bow or stern;

[0019] (5) During the fish gathering stage, each row of LED fish attracting lights is turned off in sequence starting from the right side of the ship, leaving only two rows of small-angle LED fish attracting lights at the farthest end of the light pole, so that the fish gather there;

[0020] (6) During the net-raising phase, the side rings and lower lines are reeled in, and then the net is hoisted and fixed to the side of the ship.

[0022] Furthermore, in the step (1), the lens angles of the LED fish attracting lights in the same row on the headlight pole are the same, while the lens angles of different rows vary. After the headlight pole is unfolded, the farther away from the side of the ship, the smaller the lens angle; the smaller the lens angle of the LED fish attracting light, the smaller the area illuminated in the water, and accordingly, the smaller the activity range of the fish, the better the attracting effect.

[0023] Furthermore, in step (1), the angle of each row of lenses of the headlight pole decreases step by step from one section of the ship's side to the farthest end, and the angles are 90°, 90°, 65°, 65°, 50°, 50°, 30°, and 30° respectively.

[0024] Technical principle of the present invention: The present invention is a dual-channel heat dissipation device for LED fish-attracting lamps. Through the dual-channel technology of active heat dissipation and passive heat dissipation, the fish-attracting lamps can achieve efficient heat dissipation, reduce the light decay of the lamp beads caused by long-term high temperature during use, thereby increasing the service life and reducing the cost of equipment maintenance and replacement. The device can effectively solve the heat dissipation problem of LED fish-attracting lamps through dual-channel heat conduction technology, reduce the light decay of the lamp beads caused by long-term high temperature, so as to always maintain a high light efficiency and a stable spectrum, accurately attract specific fish, and improve the efficiency of fish gathering. Good heat dissipation allows the LED lamp beads to work at a suitable temperature with higher luminous efficiency. Under the condition of achieving the same fish-attracting effect, compared with traditional fish-attracting lamps or LED fish-attracting lamps with poor heat dissipation, the energy consumption is greatly reduced, fuel or electricity costs are saved, and the costs caused by frequent replacement of lamp beads and equipment maintenance are also reduced. Dual-channel heat conduction can prevent LED lamp beads from aging rapidly due to overheating, reduce light decay, extend the service life of LED fish-attracting lamps, reduce the equipment update cost of fishermen, and improve the return on investment of equipment. The efficient heat dissipation system can reduce the risk of safety accidents such as fire caused by overheating of equipment, improve the safety of fishery operations, and make fishermen feel more at ease when operating at sea. LED fish attracting lights are mercury-free and UV-free, while dual-channel thermal conductivity technology further improves their performance and stability, reduces waste and environmental pollution that may be generated by equipment failure or frequent replacement, and helps achieve green and sustainable development of the fishery industry.

[0025] Beneficial effects of the present invention: The present invention solves the problem that the LED fish attracting lamp is limited in size and often has poor heat dissipation effect, resulting in reduced light efficiency, thereby reducing the life of the LED fish attracting lamp. A dual-channel heat dissipation device for LED fish attracting lamps is designed. Through dual channels of active heat dissipation and passive heat dissipation, efficient heat dissipation of the fish attracting lamp is achieved, and the light decay of the lamp beads caused by long-term excessive temperature during use is reduced, thereby increasing the life and reducing the cost of equipment maintenance and replacement. Based on the study of the phototaxis behavior of fish, the present invention further designs the lighting control scheme and the lens angle of the fish attracting lamp, which can achieve the final gathering of fish in the middle position of the net, and has the characteristics of fast and high efficiency, so as to achieve the best effect of pumping as many catches as possible onto the boat. Compared with the traditional process of luring, gathering, driving and netting, the fast and efficient light-induced fish attracting system and its use method for attracting oceanic saury proposed by the present invention can improve the fishing efficiency of the side net saury fishing boat, greatly improve the fishing output and the economic benefits of a single fishing.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0040] See also Figure 1 , Figure 2 The technical solution adopted by the present invention is: a dual-channel heat-conducting high-efficiency LED fish-attracting and fishing-aiding device, characterized in that it includes: an LED fish-attracting lamp 1, a wire 2, a switch 3, and a rectifier 4. The LED fish-attracting lamp 1 is equipped with a specially designed high-efficiency LED lamp group, which is distributed on the lamp pole and is a key component for realizing the fish-attracting function. It is connected to the switch 3 and the rectifier 4 in sequence through wires, and its luminous intensity and wavelength and other parameters are designed according to the phototropism characteristics of fish;

[0041] According to this embodiment, the switch 3 is connected to the rectifier 4 at one end through a wire, and is connected to the LED fish attracting lamp 1 at the other end, and plays a role in circuit transmission and signal transmission, and can control the switch and color switching of the LED fish attracting lamp 1 connected thereto;

[0042] According to this embodiment, one end of the rectifier 4 is connected to the cabin power supply, and is used to receive AC power and convert it into DC power and output it to the switch 3 and the LED fish attracting light 1.

[0043] According to this embodiment, the LED fish attracting lamp is divided into a flat mirror LED fish attracting lamp and a small angle LED fish attracting lamp according to the different light emitting angles of the lens. Figure 3 ;

[0044] According to this embodiment, three flat lens LED fish attracting lamps are installed on the small lamp pole, and each fish attracting lamp can realize the free switching of red and white light; the small angle LED fish attracting lamp is mainly installed on the large lamp pole. Please refer to the flat lens LED fish attracting lamp and the small angle LED fish attracting lamp for details. Figure 7 , Figure 8 .

[0045] See also Figure 11 to Figure 12 The small light poles are arranged around the left and right sides, bow and stern of the ship, and the distance between the two small light poles is about 1 meter; the large light pole is installed in the middle of the starboard side, is about 15 meters long, and the farthest end is approximately above the middle position of the net. 8 rows of LED fish attracting lights are installed on the large light pole, 3 in each row, for a total of 24;

[0046] See also Figure 4 , Figure 5 The dual-channel heat conduction LED fish attracting and aiding fishing device includes a dual-channel heat conduction structure, including passive heat dissipation structure, active heat dissipation structure, material selection, sealing and waterproof design, optical design, and circuit design. The specific design is divided into the following parts:

[0047] (1) Passive heat dissipation structure

[0048] Passive heat dissipation structures usually include corrugated heat sinks and wind shields. The corrugated heat sink design can increase the heat dissipation area and improve the heat dissipation efficiency. The wind shield is used to change the direction of hot air flow, promote air circulation, and accelerate the heat dissipation process1.

[0049] (2) Active heat dissipation structure

[0050] The active heat dissipation structure is mainly realized by the heat dissipation fan. The heat dissipation fan uses air cooling to force the heat generated by the LED lamp beads to be removed. Usually, the heat dissipation fan is fixed on the fan connection plate and connected to the wavy heat sink through a fixed plastic plate to form an effective heat dissipation system.

[0051] (3) Material selection

[0052] Choosing materials with good thermal conductivity and corrosion resistance is crucial for heat dissipation and device life. For example, aluminum frames, stainless steel pressure plates, and silicone anti-collision strips are all good choices. These materials can not only effectively conduct heat, but also protect the device from physical damage.

[0053] (4) Sealed and waterproof design

[0054] Since fish attracting lights are usually used in humid or underwater environments, they need to have a good sealing and waterproof design. By setting sealing grooves around the lower end of the aluminum frame and installing sealing rings, it can effectively prevent moisture intrusion and protect the LED light-emitting module and other electronic components.

[0055] (5) Optical design

[0056] The selection and design of the optical lens will also affect the performance of the fish attracting light. The optical lens made of PC plastic has good strength and light transmittance, which can ensure the effective propagation and coverage of light.

[0057] (6) Circuit design

[0058] Circuit design should consider parameters such as the working voltage, power and switch type of LED lamp beads. Reasonable circuit design can ensure the stable operation of LED lamp beads and extend their service life.

[0059] The LED fish attracting lamp includes a cooling fan 5, a fan connecting plate 6, a fixing plastic plate 7, a wavy heat sink 8, a wind baffle 9, an anti-collision rubber strip 10, a wiring terminal 11, an aluminum frame 12, an LED light-emitting module 13, a sealing ring 14, an optical lens 15, and a stainless steel pressing plate 16;

[0060] According to this embodiment, the LED light emitting module 13 is the core component for generating light source, which has high light emitting efficiency and can emit a specific spectrum to attract fish. High-brightness and high-quality LED lamp beads are usually used, which will generate more heat when working.

[0061] According to this embodiment, the heat dissipation fan 5 is fixed to the upper end of the fan connecting plate by a plurality of fixing screws;

[0062] According to this embodiment, a fixed plastic plate 7 is provided at the lower end of the fan connecting plate 6; the cooling fan 5, the fan connecting plate 6 and the fixed plastic plate 7 are fixedly connected to the wavy heat sink 8 as a whole by a plurality of fixing screws 17;

[0063] According to this embodiment, the lower end of the wavy heat sink is connected to the aluminum frame 12; the anti-collision rubber strip 10 is fixed around the plane of the wavy heat sink 8 of the aluminum frame;

[0064] According to this embodiment, a terminal 11 mounting seat is provided on one side of the aluminum frame 12, and a terminal 11 is threadedly connected to one side of the terminal mounting seat;

[0065] According to this embodiment, the LED light-emitting module 13 is mounted in a groove of the aluminum frame 12 opposite to the plane where the wavy heat sink 8 is located by fixing screws 17;

[0066] According to this embodiment, a stainless steel pressing plate 16 is provided on one side of the optical lens 15, and the optical lens 15 and the stainless steel pressing plate 16 are fixed to the mounting surface on the back of the aluminum frame 12 by fixing screws 17. The optical lens 15 focuses and adjusts the angle of the light emitted by the LED lamp beads so that the light forms a specific illumination area in the water to attract fish. The power supply and control module adjusts the working parameters of the lamp beads according to the settings to achieve the best fish attracting effect.

[0067] The dual-channel heat conduction structure includes a combination of active heat dissipation by the cooling fan and passive heat dissipation by the wavy heat sink to improve the heat dissipation efficiency; when the device is working, the LED lamp beads emit light to generate heat, and the heat is transferred to the heat dissipation fins through the substrate, and the natural air cooling channel starts to work, and the surrounding air naturally convects to take away some of the heat. At the same time, the fan in the fan heat dissipation channel starts to force air flow, and the cold air is blown to the lamp beads and the heat dissipation fins, and is discharged from the device after absorbing the heat. The two channels work together to dissipate heat efficiently, ensuring that the LED lamp beads work at a suitable temperature and maintain luminous efficiency.

[0068] The passive heat dissipation calculation can be based on the formula:

[0069]

[0070] Where A is the area perpendicular to the direction of heat transfer, in m 2 ; T h With T care the temperatures of the high and low temperature surfaces, respectively, in °C; δ is the distance between the two surfaces, in m; λ is the thermal conductivity of the material, in W / (m·°C)

[0071] Active heat dissipation calculation can be based on the formula:

[0072] Q=hA(T w -T air )

[0073] in:

[0074] A is the area perpendicular to the direction of heat transfer, in m 2 ; T w and Tair are the temperatures of the solid wall and fluid, respectively, in °C; h is the convective heat transfer coefficient. Figure 6 .

[0075] According to this embodiment, the aluminum frame 12 is provided with a wind shield 9 at the middle of the back, and further includes a reinforcing rib 19; the reinforcing rib 19 is located around the front edge of the aluminum frame; the dual-channel heat conduction structure is characterized in that it also includes a top column 18;

[0076] See also Fig. 9 , Fig.10 , the top column 18 is located on the wave heat sink 8; the dual-channel heat conduction structure is characterized in that the aluminum frame 12, the wave heat sink 8, the wind baffle 9, the reinforcing rib 19, the screw holes and the top column 18 are formed by pressure casting;

[0077] According to this embodiment, the dual-channel heat conduction structure is characterized in that the aluminum frame 12 is made of ADC12 type die-cast aluminum alloy;

[0078] According to this embodiment, the dual-channel heat conduction structure is characterized in that the wavy heat sink 8 is located on the back of the aluminum frame 12, and is divided into two symmetrical parts on the left and right by the wind shielding plate 9. Each side is composed of 72 wavy heat sinks 8 of different lengths, and the angle between two heat sinks is 5°.

[0079] Furthermore, the method for using the small-angle LED fish-attracting lamp on the headlight pole comprises the following steps: dividing the side-net fishing boat into three areas, namely, the left half area, the right half area, and the headlight pole fish-taking area, and placing a long lamp pole and several LED fish-attracting lamps with changing lens angles at the net-lowering position; when fishing, all the LED fish-attracting lamps are turned on for a period of time to complete the fish-attracting, and then the LED fish-attracting lamps on the small lamp poles in the left and right halves are turned off in sequence from the middle of the left side of the fish-taking part through the switch in the control room, and the saury are gradually attracted to the headlight pole above the net according to the closing sequence; at this time, the rows of fish-attracting lamps on the headlight pole are turned off in sequence to the outermost side of the lamp pole, the lens angle of the outermost fish-attracting lamp is the smallest, and the area illuminated on the sea surface is small, the activity area of ​​the saury is small and in the middle of the net, at this time, the side ring net and the lower net are reeled in, and then the net is hoisted and fixed to the side of the boat, and the fish are gathered at the fish suction pump to complete the fishing operation through pump suction.

[0080] The present invention is further illustrated by a specific embodiment below.

[0081] 1. Regional division of fishing vessels

[0082] The saury boats are divided into three areas: A, B, and C. Area A is the left half, area B is the right half, and area C is the center area of ​​the large light pole for laying nets. Small light poles are installed in areas A and B, and 3 LED fish-attracting lights with flat lenses are installed on the small light poles. Each fish-attracting light can freely switch between red and white light. The small light poles are placed around the left and right sides of the ship, the bow, and the stern, and the distance between the two small light poles is about 1 meter; a large light pole is installed in area C. In the middle of the starboard side, about 15 meters long, the farthest end is approximately above the middle of the net placement. 8 rows of LED fish-attracting lights are installed on the large light pole, 3 in each row, for a total of 24.

[0083] 2. Installation of LED fish attracting lights on headlight poles

[0084] The headlight pole is located in the middle of the starboard side, about 15 meters long, and the farthest end is approximately directly above the middle of the laying net. There are 8 rows of LED fish-attracting lights installed on the headlight pole, 3 in each row, for a total of 24. The lens angles of the LED fish-attracting lights in the same row are the same, while the lens angles of different rows vary. After the headlight pole is unfolded, the farther away from the ship's side, the smaller the lens angle. The lens angle of each row of the headlight pole decreases in steps from the ship's side to the farthest end, and the lens angles are 90°, 90°, 65°, 65°, 50°, 50°, 30°, and 30°, respectively.

[0085] 3. Fish gathering stage

[0086] Use a sea-sweeping high-intensity light to gradually attract the fish schools in the distance to the vicinity of the boat, and then turn on the white light of the LED fish-attracting light to make the saury gather around the boat.

[0087] 4. Stabilizing the fish stage

[0088] When the density of fish around the hull reaches a certain level, the white light will be switched to red light to reduce the range of fish activity, thus stabilizing and gathering fish.

[0089] 5. Fishing Stage

[0090] When the fish school moves stably under the red light, the red lights of the small lamp poles are turned off in sequence from the port side of areas A and B to the big lamp pole on the right side of the ship, leaving only the red light of the big lamp pole in area C. The fish school chases the red light and gathers in area C via the bow or stern.

[0091] 6. Fish gathering stage

[0092] Starting from the right side of the ship, each row of LED fish-attracting lights is turned off in turn, leaving only two rows of small-angle LED fish-attracting lights at the farthest end of the light pole, so that the fish will gather here.

[0093] 7. Net lifting and pumping stage

[0094] At this time, the side ring line and the lower line are reeled in, and then the net is hoisted and fixed to the side of the ship. The crew then gathers the net from both sides of the bow and stern to the middle to form a "pocket" shape, and pulls the net to pull the fish to the fish suction pump, turns on the fish suction pump, and catches the fish.

[0095] On the other hand, the method of using a high-efficiency LED fish attracting and aiding fishing device with dual-channel heat conduction mainly includes the following steps:

[0096] (1) Installation: Fix the fish attracting light at an appropriate position on the vessel, making sure the light is stable and avoid shaking.

[0097] (2) Connect the power supply: Connect the marine DC power supply through the terminal block to ensure a stable power supply.

[0098] (3) Adjust the beam angle: Adjust the angle of the optical lens as needed to ensure that the light covers the target sea area.

[0099] (4) Turn on the equipment: Activate the fish attracting light and adjust the brightness and color to attract specific types of fish.
