Description

Technical Field

[0001] The present invention relates to the field of marine fishing LED lighting technology, and in particular to a unit light source of an LED underwater fish attracting lamp placed underwater to attract fish below the water level and far from a fishing boat, and to gather fish toward the light for fishing. Background Art

[0002] The ocean, which accounts for 70% of the earth, is rich in oil, natural gas and mineral resources, as well as rich biological resources, providing food or feed for humans, represented by fish, crustaceans and cephalopods. There are about 200,000 species of organisms in the ocean, of which about 19,000 are known fish, and about 20,000 are cephalopods and crustaceans (hereinafter collectively referred to as "fish"). Based on the most primitive food in the biological food chain - aquatic plants - it is calculated that the annual production of marine fish in the world is about 600 million tons. Except for young fish, small fish in the food chain and natural extinction, about 50% of the fishery resources are catchable, that is, the annual catchable fish in the world's oceans is about 300 million tons / year. The annual fish catch in the world basically remains at around 100 million tons, so there is still considerable development prospect for marine fish resources. Due to human activities, environmental degradation and overfishing, fish are becoming less and less in the near sea (about 50m deep), so people have to use fishing boats to go to the open sea and the ocean. In order to increase the catch and time efficiency, fishing is not only done during the day, but also at night. Lights are used to lure fish, which is the premise and background for the birth of fish attracting lights. Therefore, fish attracting lights are also called "fishing lights" or "fish attracting lights".

[0003] Phototaxis is a characteristic of fish and other aquatic economic animals that produce directional behavioral responses to light stimulation. The directional behavior of fish moving toward a light source is called positive phototaxis, while the behavior moving away from a light source is called negative phototaxis. By utilizing the positive phototaxis of fish, we can design positive phototaxis light sources and develop and apply them on fishing boats and in the surrounding waters to increase the catch. At the same time, we also pay attention to the spectrum, illumination, and light flickering that avoid the generation of negative phototaxis that drives fish away.

[0004] The requirements for light fishing are mainly related to the following factors:

[0005] First, the sensitivity curves of different fisheyes to different color temperatures and chromaticities are different;

[0006] Second, fish have a certain range of suitable illumination and will cluster in the water layer with this illumination;

[0007] Third, the contrast sensitivity of fish is related to the water temperature and the intensity of background light (moonlight);

[0008] Fourthly, when visible light propagates in seawater, the light intensity decays continuously with increasing depth due to the absorption and scattering of light. Moreover, the attenuation coefficients of light of different wavelengths are also different. The attenuation coefficient is also related to the concentration of organic matter and suspended matter in the seawater. Therefore, its attracting range will also change.

[0009] The theoretical basis of fish gathering technology comes from long-term experiments and practices, and these laws provide us with the corresponding basis for the design of the spectral range and luminous intensity of fish gathering lights. In this way, we can use the phototropism of fish to make fish schools distributed in a large area gather in a small area, and fish schools distributed in deep waters gather in shallow water fishing areas, forming dense, fishable schools with fishing value for fishing.

[0010] Fish attracting lights are the most important fishing aids in light-lured fishing operations. They can be divided into two categories: onboard lights and underwater lights. When used together, they can not only attract deep-seated fish to shallower water layers for fishing at night, but also gather large fish at a certain depth for capture during the day.

[0011] Fish attracting lamps have been used in fishing operations since the 1990s. At present, the main light source is metal halogen lamps. Metal halogen lamps (HID) (formerly known as "halide dysprosium iodine lamps") are thermal light sources, that is, most of the energy is converted into heat energy, and part of the energy is converted into light energy. The development of metal halogen lamps for fishing has greatly increased the catch of fisheries due to the effect of light.

[0012] However, the luminous principle of metal halogen tungsten lamp is the same as that of incandescent lamp, and it has its insurmountable disadvantages, which are mainly manifested in:

[0013] 1) The luminous efficiency is low, requiring a larger marine power, wasting a lot of energy;

[0014] 2) The luminous spectrum of metal halogen tungsten lamps includes invisible light spectra such as ultraviolet light and infrared light, so the light utilization rate is low;

[0015] 3) The central wavelength, color temperature and color are fixed and cannot be adjusted, which does not meet the fishing requirements of different fish species that are phototropic to different spectra;

[0016] 4) Poor waterproof performance, difficult to adapt to the harsh environment of offshore operations, especially not suitable for underwater fish attracting lamps, so halogen tungsten lamps are only tested or tried on very few fishing boats for underwater fish attracting lamps;

[0017] 5) The glass shell of halogen tungsten lamp has poor mechanical strength and is not suitable for the pressure of underwater lamps in deep sea (such as the maximum depth of squid fishing boat underwater fish gathering lamp is 300m, and the water pressure is 30atm). It is also difficult to be used in the harsh marine environment of strong winds, waves, rain and snow where the lamps on board are located. It is easy to break, which not only increases the cost of use and maintenance, but also the safety hazards caused by the high voltage power supply to the crew after the halogen tungsten lamp is damaged, and the harmful substances (heavy metal "dysprosium") in it will pollute the seawater, which are problems that cannot be ignored;

[0018] 6) Short service life. Generally, the service life of metal halogen tungsten lamps is only about 3000 hours, which increases the cost of use.

[0019] Light Emitting Diode (LED) is a solid-state light source that emits light in an electroluminescent manner. It belongs to the category of cold light sources and is a semiconductor device that directly converts electrical energy into visible light and radiation energy. It has been developed in my country for nearly 20 years. Since 2010, it has entered a mature stage of large-scale application and has been widely used in display light sources, outdoor lighting, indoor lighting, decorative lighting, special lighting and other fields. Since 2012, the research and development and industrialization of LED fish attracting lamps have begun. Its main advantages over metal halogen tungsten lamps are:

[0020] 2) Theoretical calculation analysis and practical application results have proved that 300W LED fish attracting lamps can replace 1000W metal halogen tungsten lamps, reducing energy consumption by more than 70%;

[0021] 2) It can control and adjust brightness, color temperature and chromaticity according to different fish species and environmental changes;

[0022] 3) LED is a solid-state light source, powered by low-voltage DC and driven by low current, with a service life of more than 25,000 hours, and is used within the safe voltage range;

[0023] 4) The LED fish attracting light is a fully solid structure with strong earthquake and impact resistance. The sealed and waterproof structure can easily meet the requirements for deep water use and is extremely easy to maintain.

[0024] 5) The LED spectrum is a discrete monochromatic spectrum with a half-width of about 30nm. LEDs of various colors have different peak wavelengths, all within the effective radiation range of the visible light spectrum. Most of the LED light is concentrated in the area where people need to radiate, with a small divergence angle, which can be effectively controlled to make full use of the luminous flux;

[0025] 6) LED light responds to current very quickly. The intensity and color of the light can be adjusted simply by adjusting the current, and adjustment and control are easy to achieve.

[0026] It can be seen that just as LED lighting fixtures replace incandescent lamps, LED fish attracting lamps replacing metal halogen tungsten lamps is an inevitable trend in the development of marine fishing light sources. Summary of the invention

[0073] The embodiment of the present invention provides a unit light source of an LED underwater fish attracting lamp, comprising: a lamp body 10, an LED lamp board 20 and a light emitting sealing component; Figure 1 and Figure 2 , the LED light board 20 includes an LED light source and a light source substrate. The LED light source can be set to multiple according to the actual embodiment, and the LED light sources are respectively installed on the light source substrates; the LED light board 20 is arranged in the lamp body 10; the LED light board 20 is installed and fixed through the mounting hole in the lamp body 10, and the light-emitting sealing component is connected to the light-emitting surface end of the lamp body 10 to seal the LED light board 20; when in use, it is necessary to place the unit light source of the LED underwater fish-collecting lamp into the depths of the ocean or lake (for example: 100 meters deep). Since the LED light board 20 is an electronic device, the LED light board 20 needs to maintain a dry environment when in use. In the embodiment of the present invention, the LED light board 20 is sealed by the light-emitting sealing component to avoid short-circuit failure caused by liquid entering the LED light board 20 during use; the light-emitting surface sealing component is provided with a high-pressure resistant glass 30, and the high-pressure resistant glass 30 is used to transmit the light emitted by the LED light board 20 to the outside. In one embodiment of the present invention, the high-pressure resistant glass 30 is made of tempered glass material to prevent the unit light source of the LED underwater fish attracting lamp from being crushed by the water depth pressure after being thrown into the depth of the ocean or lake (e.g., 100 meters). The high-pressure resistant glass 30 is a light-transmitting material, and the light emitted by the LED light board 20 is irradiated outward through the high-pressure resistant glass 30, and the light is used to lure fish for fishing.

[0074] In the embodiment of the present invention, by adopting LED light source as the lighting source, replacing the traditional metal halide lamp currently used as the light source, the energy saving rate reaches more than 60%, achieving the purpose of being green, environmentally friendly and energy-saving; the LED lamp is a "solid-state lighting lamp", replacing the metal halide lamp with a glass shell, so that the service life is increased from about 2000h to more than 30000h, reducing the use cost and maintenance cost; the LED lamp board 20 is sealed by connecting the light-emitting sealing component with the light-emitting surface end of the lamp body 10; the structure is compact and has multiple waterproof and moisture-proof functions. The light-emitting surface sealing component is provided with high-pressure resistant glass 30, which is used to transmit the light emitted by the LED lamp board 20 to the outside, and the metal skeleton structure of the lamp body 10, so that the LED light source as a lighting source has the functions of high mechanical strength, high resistance to seawater corrosion, and high and low temperature resistance.

[0075] In addition, the present invention is a lighting unit that can be combined in a variety of ways according to lighting power requirements. The combination is flexible and convenient, so that underwater fish attracting lights can be better popularized and promoted.

[0076] In one embodiment of the present invention, the lamp body is made of aluminum alloy. Specifically, the lamp body 10 is made of stainless steel 1Cr18Ni9Ti (321) forgings through mechanical processing. The stainless steel forgings have the advantages of high mechanical strength, corrosion resistance, high and low temperature impact resistance, moisture-proof and waterproof functions. Because it is a forging material, its metal structure is fine and leak-proof.

[0077] In one embodiment of the present invention, the light source substrate adopts a copper substrate to reduce thermal resistance so that the heat emitted by the LED light source can be transferred to the lamp body 10 as quickly as possible; the light source is composed of 100 LED package patches with a power of 1W, that is, the total power of the unit light source is 100W; it is arranged in a 10×10 matrix structure, and is electrically connected in a full series / parallel mesh combination, and is mechanically fixed on the light source substrate; the LED patch is composed of white light LEDs, and its correlated color temperature is 5500K±300K; the average luminous efficiency is 100Lm / W; the designed downward light irradiation depth and side light irradiation distance are both 100m.

[0078] Continue reading Figure 1 and Figure 2The light-emitting sealing assembly further includes: a face ring 50, a shock-absorbing plastic ring (not shown) and a sealing ring 40. One end face of the sealing ring 40 is connected to the light-emitting surface of the lamp body 10, and the other end face of the sealing ring 40 is connected to one end face of the high-pressure resistant glass 30, and is used to seal the gap between the lamp body 10 and the high-pressure resistant glass 30. Specifically, since the lamp body 10 and the high-pressure resistant glass 30 are respectively made of rigid materials, there is a connecting gap between the lamp body 10 and the high-pressure resistant glass 30. The sealing ring 40 is a plastic part. The gap between the lamp body 10 and the high-pressure resistant glass 30 is sealed by pressing and locking, providing a sealed environment for the LED light board 20 in the lamp body 10.

[0079] One end face of the shock-absorbing plastic ring is connected to the high-pressure resistant glass 30; the face ring 50 is connected to the other end face of the shock-absorbing plastic ring. Since the face ring 50 and the high-pressure resistant glass 30 are respectively made of rigid materials; the face ring 50 and the high-pressure resistant glass 30 are in close soft contact through the shock-absorbing plastic ring.

[0080] The high pressure resistant glass 30, the shock absorbing plastic ring and the face ring 50 are respectively provided with a first through hole, and the locking member (fastening bolt 90) is connected to the lamp body 10 through the first through hole, and is used to compress and lock the high pressure resistant glass 30, the shock absorbing plastic ring, the sealing ring 40 and the face ring 50.

For example, 8 first through holes can be provided at equal distances. The first through hole is located around the edge of the light-emitting surface of the lamp body 10. This allows the high-pressure resistant glass 30, the shock-absorbing plastic ring, the sealing ring 40 and the face ring 50 to be better pressed and locked. At the same time, the space between the high-pressure resistant glass 30 and the lamp body 10 for the LED lamp board 20 is better sealed.

[0083] In one embodiment of the present invention, the high pressure resistant glass is a high pressure resistant and corrosion resistant glass. Specifically, the high pressure resistant glass 30 is made of tempered glass. According to the pressure requirement of diving at a depth of 100m, a high pressure glass with a thickness of 10mm is selected. The edge of the high pressure resistant glass 30 has 8 openings at equal distances corresponding to the openings around the edge of the upper portion of the lamp body 10. The openings are the same, so as to facilitate fixing with the lamp body 10, the sealing ring 40, the shock-absorbing plastic ring, the face ring 50 and other components.

[0084] In one embodiment of the present invention, the shock-absorbing plastic ring is made of polytetrafluoroethylene plastic, which is the same material as the sealing ring 40; the shock-absorbing plastic ring is placed between the high-pressure resistant glass 30 and the face ring 50 to reduce the pressure of the face ring 50 on the high-pressure resistant glass 30, so that the face ring 50 and the high-pressure resistant glass 30 can achieve close soft contact through the hole.

[0085] In one embodiment of the present invention, the face ring is made of aluminum alloy, specifically, the face ring 50 is composed of stainless steel 1Cr18Ni9Ti with high strength, corrosion resistance, high and low temperature resistance, moisture and water resistance, and certain mechanical strength; it is placed on the shock-absorbing plastic ring, and the face ring 50 is matched with the shock-absorbing plastic ring, the high-pressure resistant glass 30, and the sealing ring 40 through fasteners to achieve a tight mechanical connection with the lamp body 10, so that the LED light source can achieve a high light output rate, and the waterproof and moisture-proof safety of the light source concave cavity of the lamp body 10 is guaranteed.

[0087] For details, please refer to Figure 2 The concave groove 101 is provided on the interface between the lamp body 10 and the sealing ring 40, and the concave groove 101 may be provided with a plurality of small pressing grooves (not shown); the sealing ring 40 is provided with a pressing step 401 adapted to the concave groove 101. The concave groove 101 is sleeved on the pressing step 401, and the concave groove 101 is used to press and fit with the sealing ring 40 to further seal the gap between the lamp body 10 and the high-pressure resistant glass 30, so as to prevent the seawater from entering the space of the LED lamp board 20 through the gap between the high-pressure resistant glass 30 and the lamp body 10 under the action of the high pressure of deep sea water.

[0088] Similarly, the lamp body 10 may be provided with a convex step, and a compression groove matched with the convex step may be provided on the sealing ring 40. The convex step and the compression groove are tightly matched to further seal the gap between the lamp body 10 and the high pressure resistant glass 30.

Bolt holes are provided on the lower plane of the concave cavity 102. In one embodiment of the present invention, four bolt holes are provided to fix the LED lamp board 20; a concave wire groove is provided under the concave cavity 102 of the lamp body 10, and the concave wire groove is used for wiring the power cable.

[0090] Continue reading Figure 1 and Figure 3 The lamp body 10 is also provided with a plurality of heat dissipation fins 103, and the heat dissipation fins 103 are used to conduct the heat emitted by the LED lamp board 20 during operation to the liquid for heat dissipation.

In one embodiment of the present invention, the heat dissipation fins 103 may be four, and the heat dissipation fins 103 may transfer the heat emitted by the LED during operation to the outer surface through the inner wall, and conduct the heat dissipation through the heat dissipation fins 103 and the seawater.

[0092] See also Figure 1 and Figure 2 The lamp body 10 is further provided with a cable installation hole 104 at the end away from the light emitting surface. The cable installation hole 104 is connected to the LED light board 20 and is used to provide an entry hole for the power supply cable. Specifically, the cable is introduced into the power supply end of the LED light board 20 through the cable installation to provide power supply to the LED light board 20.

[0094] Furthermore, in one embodiment of the present invention, the cable installation hole 104 can also be sealed by filling waterproof glue. For example, when the unit light source of the underwater fish attracting lamp needs to be placed in the deep sea, in order to prevent seawater from seeping into the cable installation hole 104 under the high pressure in the deep sea.
