Description

  The present invention relates to an underwater fishing light that collects fish by being submerged in water.

  In recent research on light collection using light, fish have a tendency to gather in light, but it has been found that depending on the fish, not only the high-illumination area but also the existence of a low-illumination area improves collection and retention However, the creation of low-light areas has been attracting attention in order to enhance the fish collection effect of the fish lamp.

For example, in Patent Literature 1, a bright area and a dark area that are clearly separated around an underwater fish lamp are formed in arbitrary directions under the name of “fish collection method using an underwater fish lamp”, and a high fishing area An invention relating to a method of collecting fish using an underwater fish collection lamp that can be easily formed is disclosed.
The invention disclosed in Patent Document 1 includes an underwater fish collection lamp including a shading tool that limits the maximum spread angle (θ) of light emission from the lamp to 300 degrees or less about the upper side, and the maximum light emission from the lamp. At least one underwater fish collection lamp equipped with a shading device that limits the spread angle (θ) to within 300 degrees around the lower side is suspended in the ship and dropped into the water. Depth adjustment is performed alternately.
In the first underwater fishing lamp provided with a light-shielding tool that restricts the maximum spread angle (θ) of light emission from the lamp to within 300 degrees centering on the upper side, a dark region is formed in the downward direction when the lamp is lit. In the second underwater fishing lamp provided with a light-shielding tool that restricts the maximum spread angle (θ) of light emission from the light source to within 300 degrees centering on the lower side, a dark region can be formed in the upward direction when it is lit. For example, in the case of squid fishing, these underwater fishing lights are suspended in the sea from the side of the ship, and both the first and second underwater fishing lights are turned on, or the first underwater fishing lights are lit. Only the lights are turned on, and the flocks in the area away from the ship are drawn around the ship. Then, when the raft is gathered around the ship, the first underwater fishing light is turned off, and if the second underwater fishing light is not lit, it is turned on. Then, if you want to gather around the ship, it will gather in a relatively shallow area in the upward dark area formed by the second underwater fishing light, so it will be possible to catch it with a fishhook, It becomes a fishing method with high fishing results.

Further, Patent Document 2 discloses an underwater fish lamp that collects fish by forming a suitable illuminance area in a donut shape in a swimming layer area having a depth of water suitable for each fish species and having a low stimulation light. An invention related to this is disclosed.
The invention disclosed in Patent Document 2 is a light source chamber that is formed of a transparent material and has a U-shaped longitudinal section, and a non-translucent material that is inserted and covered from above on the peripheral side surface of the upper end portion of the light source chamber. The cover cap is formed at the center position of the cover cap, the reflecting plate and the bottom reflecting plate attached to the upper and lower positions of the inner surface of the cover cap and the inner surface of the bottom surface of the light source chamber, respectively. And a water access hole formed in each of the light source chamber and the cover cap.
And when this underwater fishing light is lowered into the water, water enters the light source chamber from the water access hole, and it will be submerged without installing a special weight, so optimal swimming according to the desired fish type When the luminous bulb is turned on by lowering it to the layered area, the light from the luminous bulb passes through the water that has entered the light source chamber and is reflected face-to-face between the reflector and the bottom reflector so that there is no irritation. It diffuses in a donut shape from the side of the light source chamber with a suitable illuminance close to the natural light preferred by fish. Above and below the most suitable illuminance band that expands in a donut shape, shadows where fish concentrate are spread over a wide area, and fish can swim a lot in this part, so that effective fish collection is possible.

And as what uses a light emitting diode, the patent document 3 discloses the invention regarding the small and lightweight fish-collecting light by which the required light quantity is obtained with the name "fish-collecting light".
The invention disclosed in Patent Document 3 includes a light emitting diode module mounted on a substrate, a light emitting diode module that covers the substrate with a case with a condensing lens that includes a condensing lens that is disposed to face the light emitting diode, and a plurality of light emitting diode modules. A light source unit having a light-emitting diode module mounted thereon, a light source unit that houses the main substrate and has a waterproof case with a light-transmitting cover on a surface facing the light-emitting diode module, and a power supply unit that supplies power to the light source unit Is provided.
Since this light emitting diode module combines a light emitting diode and a condensing lens, it is possible to dramatically improve the light intensity as compared with the light intensity of a conventional light emitting diode. Since the number of light emitting diodes can be reduced, the weight can be reduced, and when suspended on a ship, it is difficult to raise the position of the center of gravity of the ship, the resilience of the ship is maintained, and the safety is excellent. In addition, by providing the cooling fins, it is possible to effectively release the heat generated in the light emitting diode module.

Hereinafter, the best mode of an underwater fish collecting lamp according to the present invention will be described with reference to FIGS.
Fig.1 (a) is a conceptual diagram of the underwater fish collection lamp concerning this Embodiment of this invention, (b) is arrow sectional drawing of the part shown by the AA line in Fig.1 (a). It is.
In FIG. 1 (a), an underwater fish lamp 1 includes a plurality of light emitting sections 2 formed in a planar shape by arranging a plurality of light emitting diodes 3 as light source sections on a rectangular substrate 4, and a plurality of light emitting diodes. 3, a battery 5 that supplies power necessary for light emission of the light-emitting diode 3, a cylindrical first housing 6 that houses the light-emitting unit 2 and has light transparency, and a cylinder that houses the battery 5. A second casing 7 having a shape is included.
In addition, the underwater fish lamp 1 has a watertight structure in which both the first housing 6 and the second housing 7 are provided with a sealing material or the like for preventing water from entering. In addition, when considering use in a deep water location, in addition to the watertight structure, both the first housing 6 and the second housing 7 are watertight even when water pressure is applied. It is desirable to have a pressure resistant structure that can hold The degree of pressure resistance may be set appropriately depending on the fish to be caught. A bottom lid 8 is fitted to one end of the first casing 6, and a second casing 7 is connected to the other end of the first casing 6 via a connecting member 9. Even if it is immersed in water, water does not enter the inside of the first housing 6 and the second housing 7.
The bottom lid 8 and the second casing 7 are respectively provided with a first locking tool 10 and a second locking tool 11 that are formed in an annular shape. Rope and weight when installing on can be locked. The shape of the first locking device 10 and the second locking device 11 is not particularly limited as long as it is a shape capable of locking a rope or the like, and is not limited to a circular, triangular, quadrangular or polygonal ring. Various shapes such as a shape in which a part of these rings is cut off are conceivable. Of course, the locking tool is a concept including a case where a hook or shackle is installed. In the present application, “annular” or “ring” does not necessarily mean only “circular” or “circular”, but may have a corner such as a polygon, and has an end. It shows a state of continuous connection.

And the 1st housing | casing 6 and the 2nd housing | casing 7 may be comprised integrally, and you may make it accommodate the some light emission part 2 and the battery 5 in one housing | casing. Further, the first housing 6 and the second housing 7 may be configured separately without being connected to each other so as to communicate with each other. In this case, handling of the entire apparatus becomes complicated by a power cable or the like that connects the first casing 6 and the second casing that are separately configured, but the second casing 7 that houses the battery 5 is a ship. If the first casing 6 that houses the light emitting unit 2 is separated while being connected by a cable, and only this is thrown into the sea, the second casing 7 has a completely watertight structure or pressure resistance. There is no need to have a structure, and there is a possibility that the second housing 7 can be simplified in structure, reduced in weight, improved in reliability, and cost merit. Further, the shape of the housing 7 is not limited to a cylindrical shape, and may be a hollow prismatic shape, a pyramid shape, a hollow spherical shape, or a polyhedral shape.
Further, the light source unit is not particularly limited to the light emitting diode 3 as long as it has directivity, but the light emitting diode 3 has a high light emission efficiency and a small amount of power for obtaining a unit light amount. In addition to being low and economical, the amount of heat generated can be kept low, so the durability to the watertight structure is high. Furthermore, since the light emitting diode 3 is a point light source, it can be freely arranged, and can be said to be a desirable light source from the viewpoint of arranging a light source having directivity. The light emitting diode 3 is not particularly limited in its emission color. For example, when a blue light with a short wavelength is used, it is known that many fish have a habit of favoring blue light as an environmental color. , There is an advantage that the collection and retention effect is high. In addition to blue, by adopting white including blue as a spectrum, it is possible to promote the collection and retention effect of fish by blue light due to scattering action in water. In the present embodiment, the light emitting diode 3 is used as the light source unit. However, the light emitting diode 3 is not particularly limited to the light emitting diode, and an ordinary light source such as a mercury lamp or a halogen lamp may be used in consideration of heat radiation. Needless to say. Further, the light emission color of the light source unit such as the light emitting diode 3 is not intended to be limited, and may be appropriately selected and changed. Furthermore, the light emitted from the light emitting unit 2 may be mixed by changing the emission color for each substrate 4 or by changing the light emission within the substrate 4, that is, for each light source unit such as the light emitting diode 3.
In the light emitting section 2, the light emitting diodes 3 have a high arrangement density at a substantially central portion in the longitudinal direction of the substrate 4, while the arrangement density of the light emitting diodes 3 is low at a substantially end portion. Will be described in detail later.

Here, in FIG. 1B, when the horizontal cross section of the first housing 6 is viewed, three light emitting portions 2 are formed by three substrates 4 arranged so that the cross-sectional shape is a substantially equilateral triangle. It is formed and configured to emit light in three directions with respect to the circumferential direction of the first housing 6.
Then, when the power of the underwater fish lamp 1 is turned on, the plurality of light emitting diodes 3 emit light upon receiving power from the battery 5, and these lights pass through the first housing 6 to be transmitted to the first housing 6. Around the body 6, three light dense portions are formed by the three light emitting portions 2.
The plurality of light emitting diodes 3 constituting the light emitting unit 2 have directivity, and when the number of the light emitting units 2 is n, the light emitting unit 2 has a directivity angle smaller than 360 / n [°]. In the present embodiment, since there are three planar light emitting sections 2, the light emitting diode 3 having a directivity angle smaller than 120 ° is selected. Therefore, in the light emitting unit 2, the light emitting diode 3 emits light within an angle range smaller than 120 °, so that the three light beams are adjacent to the dark portion of the three light around the first housing 6. The light part can be formed. That is, three pairs of dark and light portions of light are formed. In this way, when the number of the light emitting units 2 is n, and the light emitting diode 3 as the light source unit constituting the light emitting unit 2 has a directivity angle smaller than 360 / n [°], the light emitting unit In a case where the surface formed by 2 forms a regular polygon in its horizontal cross section, it is desirable because light emitted from any light emitting unit 2 does not interfere. Of course, the same applies to the light emitting section 2 having a regular n-gonal horizontal section. Thus, when forming a regular polygon, since the light shade part is formed at fixed intervals, it is possible to further improve the collection and retention of fish.
The directivity angle may be formed by a reflector of the light emitting diode 3 or the like, or the directivity angle may be formed by the structure of the light emitting diode 3 without using a reflector.

Next, FIG. 2 is a conceptual diagram when the light emitting area of the underwater fish lamp according to the present embodiment is viewed from above. In the present embodiment, 60 ° is selected as the directivity angle smaller than the aforementioned 120 °.
In FIG. 2, when the underwater fish lamp 1 is turned on and submerged in the sea and viewed from above, it is adjacent to the three dark portions 12 formed in the direction of approximately 60 ° in the circumferential direction of the underwater fish lamp 1. In the circumferential direction of the underwater fish lamp 1, three light portions 13 are formed in approximately 60 ° directions. In the sea, food organisms such as benthic animals of different types gather in the dark portion 12 and the light portion 13 of light. Then, fish such as horse mackerel are attracted to the dark portion 12 of light and gather around the underwater fishing lamp 1 to actively search for and feed for food organisms gathering in the underwater fishing lamp 1. In the light shading regions arranged at intervals as described above, feeding such as horse mackerel is performed over the entire circumference of the light source, and at the same time, the light shading portion 13 is also used as a resting place. Thus, it is possible to retain fish for a long time over the entire circumference in the circumferential direction of the underwater fishing lamp 1 by creating and arranging a light portion of light. In addition, as described later, large fish-eating predators such as large horse mackerel and sea squid tend to prey in the shadow area of the surrounding light rather than the light irradiation area, and collected It was thought that it was located in a place where it was easy to capture. For this reason, in order to lengthen the residence time of fish and the like around the underwater fishing lamp 1, a light shading portion is continuously formed while forming a light shading portion in the circumferential direction of the underwater fishing lamp 1. It is considered important to make it movable.

In order to improve the collection and retention over the entire circumference of the light source, there must be at least two pairs of dark and light portions in the circumferential direction of 360 °. If the directivity angle is 180 ° between the dark portion and the light portion of a pair of light, it becomes linear when connecting the dark portion and the light portion, and when there are at least two pairs of the dark portion and the light portion, A circular orbit is not formed when tying is connected to dark, light, dark, and light. That is, at least two dark portions of light are required, and a plurality of light emitting portions are required. Further, in order to form at least two dark portions, it is necessary to arrange at least two of the plurality of pairs of light emitting portions 2 so that they do not exist on the same plane. Furthermore, it is desirable that the light emitted from the at least two light emitting units 2 does not interfere. In particular, as shown in FIG. 2, when the light shades are formed at regular intervals, the trajectory connecting the light darks and the pales is close to a regular polygon and close to a circle. This is desirable from the viewpoint of forming a circular orbit.
As described above, in the present embodiment, a plurality of light emitting units 2 are provided, and a plurality of pairs of dark and light portions of light are regularly arranged, so that it is more suitable for fish than conventional underwater fishing lights. It provides a bait space and makes it possible to improve the collection and retention of fish. Therefore, fishermen can raise more catches, and at the same time, by providing light shading areas, they can selectively catch the target fish species among small fish and large fish. It is also possible.

Next, the light source part of the underwater fish lamp according to the present embodiment will be described with reference to FIGS.
FIG. 3A is a conceptual diagram for explaining the light source unit of the underwater fish lamp according to the present embodiment, and FIG. 3B is a conceptual diagram similarly showing a light emission state of the underwater fish lamp from the side. (C) is the conceptual diagram which looked at the mode of luminescence of an underwater fish collection lamp from the front similarly.
In FIG. 3A, the underwater fish lamp 1 uses two types of light emitting diodes 3a and 3b, and a directivity angle is provided at the longitudinal direction of the first housing 6, that is, at the substantially central portion of the light emitting unit 2 in the water depth direction. Is disposed on the substrate 4, while the light emitting diode 3 b having a directivity angle of 70 ° is disposed on the substrate 4 at the substantially end portion of the first housing 6, that is, the substantially end portion of the light emitting portion 2. is set up. Although only a part is shown, each light emitting diode 3a having a directivity angle of 20 ° emits light having a directivity angle of 20 °, and each light emitting diode 3b having a directivity angle of 70 ° has a light emitting diode 3a. The light emitting diode 3b emits light having a directivity angle of 70 °. Further, the light emitting diodes 3a at the substantially central portion have a higher arrangement density than the light emitting diodes 3b at the substantially end portions.
3 (b) and 3 (c), when the overall light emission state of the underwater fishing lamp 1 is viewed as a whole, the light emitting diodes having a directivity angle of 20 [deg.] Arranged closely at the substantially central part of the light emitting part 2 are shown. 3a emits light having a directivity angle of 20 °, and the light is concentrated in a narrow range to form a strong light emitting region. On the other hand, at the substantially end portion of the light emitting section 2, light emitting diodes 3b having a directional angle of 70 ° arranged sparsely emit light having a directional angle of 70 °, diffuse the light over a wide range, and the number of installations is also large. Since there are few, the light emission area | region 15 of slightly weak light is formed. In this way, the first housing 6 of the underwater fish lamp 1 is reduced by narrowing the directivity angle while making the arrangement density of the light emitting diodes 3a at the substantially central portion of the light emitting portion 2 higher than the light emitting diodes 3b at the substantially end portions. In the longitudinal direction, a light shade region is formed so that a circular orbit can be formed also in the longitudinal direction of the underwater fish lamp 1, that is, in the water depth direction. In other words, a light-rich area is formed in the approximate center, attracting prey organisms such as plankton and benthic animals and small fish grouped together, and the upper side, that is, the shallower area, or the lower side, that is, the deeper area. In addition, the area where large fish can be hidden is formed to improve collection and retention even in the shallow water depth direction.

In this way, by making it possible to form a circular trajectory not only in the circumferential direction of the underwater fish lamp 1, but also in the water depth direction, it is possible to create a light concentrated area in both the circumferential direction and the longitudinal direction (water depth direction) of the underwater fish lamp. A light area can be formed, and a fishing ground that can be collected and retained three-dimensionally around the underwater fishing light can be formed, thereby enabling efficient fishing and increasing the catch. Can do it.
In the present embodiment, the light emitting diode 3a emits light having a directivity angle of 20 ° at a substantially central portion of the light emitting portion 2, and the light emitting diode 3b emits light having a directivity angle of 70 ° at a substantially end portion. However, it is not particularly limited to these directivity angles, and the directivity angle of the light-emitting diode installed at the substantially central portion may be smaller than that of the light-emitting diode installed at the substantially end portion.

FIG. 4 is a conceptual diagram when the light emitting area of the underwater fish collecting lamp according to the present embodiment is viewed from the side.
As described above, in the present embodiment, light emitting diodes having a small directivity angle are densely arranged at a substantially central portion in the longitudinal direction of the light emitting portion, and light emitting diodes having a large directivity angle are sparsely arranged at substantially end portions on both upper and lower sides. As shown in FIG. 4, in the longitudinal direction of the underwater fish collection lamp 1, a bright light emitting region 14 is formed at a substantially central portion, and a slightly dark light emitting region 15 is formed at a substantially end portion. Even in the longitudinal direction of the fish lamp 1, a light intensity distribution can be formed. Therefore, the effect of improving the collection and retention of fishes due to the formation of dark and light portions of a plurality of pairs of light in the circumferential direction of the underwater fish lamp 1 can be expected in the longitudinal direction, that is, in the depth direction.
In the present embodiment, light emitting diodes having different directivity angles are arranged at approximately the center and approximately the end of the light emitting section, and the distribution of the light intensity in the longitudinal direction of the light emitting section is emphasized. However, it is possible to form a light intensity distribution in the longitudinal direction of the light-emitting portion by simply changing the number of light-emitting diodes having the same directivity angle.

Next, a heat dissipation method for the underwater fish lamp according to the present embodiment will be described with reference to FIG.
FIG. 5 is a conceptual diagram showing the internal structure of the underwater fish collection lamp according to the present embodiment.
In FIG. 5, a first heat dissipating member 16 is installed on the first housing 6 side and a second heat dissipating member 17 is installed on the second housing 7 side in the underwater fish lamp 1. Yes. The first heat radiating member 16 has a rod shape and is disposed on the back side of the substrate 4 so as to pass through the substantially center of the first housing 6, and one end portion penetrates the first housing 6 and the bottom cover 8. In contact with the insertion member 10a of the first locking tool 10 inside. On the other hand, the other end of the first heat radiating member 16 extends through the first housing 6 and the connecting member 9 to the second housing 7. And the 2nd heat radiating member 17 is rod-shaped similarly to the 1st heat radiating member 16, passes through the approximate center of the 2nd housing | casing 7, The one end part is the other end part of the 1st heat radiating member 16, and It arrange | positions so that it may not contact, and the other end part is arrange | positioned so that the 2nd locking tool 11 may be contacted.
The first heat radiating member 16 is not in contact with the substrate 4, and the heat generated with the light emission of the light emitting diode installed on the substrate 4 is transmitted to the first heat radiating member 12 through the air, and the first heat radiating member 16 The heat dissipating member 16 dissipates the transmitted heat to the outside via the first locking member 10 on the one end side. Further, on the other end portion side of the first heat radiating member 16, heat is transferred to the second heat radiating member 17 through the air, and the second engaging member 11 on the other end portion side of the second heat radiating member 17 is externally provided. To be dissipated. In the second heat radiating member 17, the heat generated by the battery accommodated in the second housing 7 is similarly transmitted to the second heat radiating member 17 through the air and passes through the second locking tool 11. And then released to the outside. Therefore, in the present embodiment, heat generated with the operation of the light emitting diode and the battery can be quickly dissipated to the outside, so that damage to the device due to heat can be prevented.
In the present embodiment, the first heat radiating member 16 and the second heat radiating member 17 are separately configured. However, they may be configured integrally, and the first locking device 10 and The second locking tool 11 can also be configured integrally. In the present embodiment, the first heat dissipating member 16 and the second heat dissipating member 17 are separately configured and arranged without contacting each other, but are configured so as to be contacted or connected to each other. May be.
Furthermore, as described with reference to FIG. 1, the first housing 6 and the second housing 7 may be configured separately without being connected to each other, such that the inside communicates. In that case, the heat radiation from the board | substrate 4 and the heat_generation | fever from a battery can be thermally radiated by respectively comprising the 1st heat radiating member 16 and the 2nd heat radiating member 17 separately. In the present embodiment, both the first heat radiating member and the second heat radiating member are formed in a rod shape, but heat transfer efficiency may be improved by providing a fin perpendicular to the rod.

Next, the amount of photons in each irradiation direction of the light emitting unit of the underwater fish lamp according to the present embodiment will be described with reference to FIGS. The measurement of this photon amount is performed by measuring 60 °, 180 ° and 300 ° when the light emitting portion 2 using the blue light emitting diode 3 as the light source portion is set to 0 ° at one vertex whose horizontal cross-sectional shape forms a substantially triangular shape. This was measured in dark air using an underwater fish lamp 1 mounted in three directions. In addition, it is common from FIG. 6 to FIG. 10 that the angle in the circumferential direction related to the measurement of the photon amount is determined from a reference in which the horizontal cross-sectional shape of the light emitting unit 2 forms one vertex that forms a substantially triangle.
FIG. 6A is a conceptual diagram showing the measurement direction of the light quantum amount of the underwater fish lamp according to the present embodiment, and FIG. FIG. 6A to 10A, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted.
In FIG. 6A, when the photon quantities in the 60 °, 180 °, and 300 ° directions shown in the circumferential direction of the underwater fish lamp 1 are measured, they are in the same direction as the installation surface of the light emitting unit 2, and therefore FIG. ), A large photon amount is measured in the vicinity of the light emitting unit 2, and the photon amount gradually decreases as the distance from the light emitting unit 2 increases.

Moreover, Fig.7 (a) is a conceptual diagram which shows the measurement direction of the optical quantum amount of the underwater fish collection lamp concerning this Embodiment, (b) is 45 degrees and 75 degrees and 165 degrees and 195 of an underwater fish collection lamp similarly. It is a conceptual diagram which shows the amount of photons in the direction of °, 285 ° and 315 °.
As shown in FIG. 7B, the photon quantities in the 45 °, 75 °, 165 °, 195 °, 285 °, and 315 ° directions in the circumferential direction of the underwater fish lamp 1 in FIG. Although a slightly large photon amount is measured in the vicinity of, the distance from the light emitting unit 2 is small at a position of 2 m.

FIG. 8A is a conceptual diagram showing the measurement direction of the light quantum amount of the underwater fish lamp according to the present embodiment, and FIG. 8B is the same for 30 °, 90 °, 150 °, and 210 of the underwater fish lamp. It is a conceptual diagram which shows the photon amount in the direction of °, 270 ° and 330 °.
Moreover, Fig.9 (a) is a conceptual diagram which shows the measurement direction of the optical quantum amount of the underwater fish collection lamp which concerns on this Embodiment, (b) is also 15 degrees, 105 degrees, 135 degrees, and 225 of an underwater fish collection lamp. It is a conceptual diagram which shows the photon amount in the direction of °, 255 ° and 345 °.
FIG. 10A is a conceptual diagram showing the measurement direction of the light quantum amount of the underwater fish lamp according to the present embodiment, and FIG. 10B is the same for the 0 °, 120 °, and 240 ° directions of the underwater fish lamp. It is a conceptual diagram which shows a photon amount.
As shown in FIGS. 8 (b), 9 (b), and 10 (b), the photon amount in any measurement direction shown in FIGS. 8 (a), 9 (a), and 10 (a). Is even smaller in the vicinity of the light emitting unit 2, and it can be seen that the range of the photon quantity that can be measured is reduced.
As shown in FIGS. 6 to 10, in the present embodiment, the photon quantities in the directions of 60 °, 180 °, and 300 ° are the strongest and widely measured in the circumferential direction of the underwater fishing lamp 1, and in other directions. The measured quantity of photon is small. Therefore, in the underwater fish lamp 1, the directivity of the selected light emitting diode is sufficiently exhibited, and it is possible to form clear dark and light portions in the circumferential direction of the underwater fish lamp 1.

Next, a prototype of the underwater fish lamp according to the present embodiment will be described with reference to FIGS.
FIG. 11 is a prototype photograph in which the underwater fish collection lamp according to the present embodiment is lit, and FIG. 12 is a prototype photograph in which the underwater fish collection lamp according to the present embodiment is lit in the sea.
In FIG. 11, two underwater fish lamps of the same shape are mounted on the table in a state where they are lit. In these underwater fishlights, the front side in the figure is a second housing that houses a battery, and a second locking tool is installed at the end of the second housing. In addition, in the back side in the figure, there is a first housing that accommodates three light emitting units, and a plurality of light emitting diodes installed in the three light emitting units emit light and a peripheral portion of the first housing You can see the scene shining brightly. However, the dark portion and the light portion of the light are not clearly formed.
On the other hand, in FIG. 12, the underwater fishing lamp is submerged in the sea with the rope locked by the second locking tool. When the underwater fish lamp is lit in the sea, three dark areas extending in three directions are clearly formed in the periphery of the underwater fish lamp, and there are light light areas around these dark areas. It can be seen that it is formed.

Below, an example is given and demonstrated about the fish collection effect of the underwater fish lamp concerning this embodiment.
In the island town of Oki Island, Shimane Prefecture, in the end of August, a pillar of a columnar reef with a structure of a 3m x 3m x 0.6m base with a length of 3.5m and a diameter of about 0.3m An underwater fish lamp was installed at a position where the water depth was about 12 m at the top end.
In Suo-Oshima Town, Yamaguchi Prefecture, in mid-October, an underwater fishing light was installed on the bottom of a stone pit that was installed for the purpose of sand control on an artificial beach at a depth of about 5m.
In any place, we observed and confirmed the collected organisms by diving observation and video images fixed on the seabed. The plankton was collected in a light-irradiated area and a non-irradiated area by a portable plankton net, and collected fish were collected.

FIG. 13A is a conceptual diagram showing an image of fish collection from the side when the underwater fish lamp according to the present embodiment is installed on the columnar reef, and FIG. 13B is also a diagram showing that the underwater fish lamp is installed on the columnar reef. It is a conceptual diagram which shows the image of the fish collection from the upper surface at the time.
13 (a) and 13 (b), in Oki Island Town, Shimane Prefecture, the underwater fish lamps form clear pairs of light dark and light areas, and the light dark areas are small The collection was remarkable, and medium- and large-sized horse mackerel were observed in the light-light part and the light-dense part of the light part. In addition, sea squids were distributed in the light part of the upper light aiming at the horse mackerel and the like.
Moreover, Fig.14 (a) is a conceptual diagram which shows the image of the fish collection from the side surface at the time of installing the underwater fish collection lamp which concerns on a present Example in a submerged dike (stone place), (b) is also an underwater fish collection lamp It is a conceptual diagram which shows the image of the fish collection from the upper surface at the time of installing in a submerged levee (stone place).
14 (a) and 14 (b), in Suo-Oshima Town, Yamaguchi Prefecture, because the transparency of seawater is low, the boundary between the dark portion and the light portion is not clear, but the light dark portion and the light portion are regular. A simple array has been formed. The collection of small horse mackerel was remarkable, but in addition, we were able to observe the sea squid and the hailfish.

In any sea area, underwater fishing lamps divide the light part of the surrounding light at moderate intervals by the dark part of light formed by light emission in three directions with high directivity, and between the dark parts of the light. It was possible to form regular bright and dark spots in which light portions were arranged so as to be sandwiched between the two. And, a remarkable collecting effect was recognized mainly for the horse mackerel, and the horse mackerel began to gather in about 30 minutes after turning on the underwater fishing light, forming a large group, and collecting and staying in the large group for about 4 hours until the extinction Was recognized. The collected horse mackerel was always observed while it was lit, and was constantly observed to eat actively.
And from the analysis results of the samples collected in the plankton net and the stomach contents analysis of the horse mackerel, it was thought that the horse mackerel selectively eats large benthic animals such as polychaetes that have started swimming in the water . Therefore, it was confirmed that fish such as horse mackerel have the habit of actively searching for and feeding on prey organisms such as plankton and benthic animals that are attracted by light and gather in the underwater fishing light and flock to the underwater fishing light. .
In addition, a lot of small horse mackerel gathered in the light emitting area of the underwater fishing light. On the other hand, many large horse mackerels appeared in places with low light, suggesting that the effect of light shading is important even in large fish. Also, in both locations, large fish-eating predators such as sea squirrels and sea bream on Suo-Oshima tend to be distributed in the shaded area of the surrounding light rather than the light irradiation area, and it is easy to capture the collected mackerel It was thought that it was located in the place.

  The result of comparing a conventional underwater fish lamp that illuminates in one direction with a light source arranged on one surface and an underwater fish lamp that illuminates in three directions with a light source arranged on three surfaces in the underwater fish lamp according to the present embodiment. Table 1 shows.

As shown in Table 1, in contrast to the conventional underwater fishlight, no horse mackerel appeared in the light part of the light, whereas in the underwater fishlight according to the present embodiment, both the dark part and the light part were large. More than 500 small and medium sized horse mackerel collected, suggesting that the formation of effective light and dark spots is important for improving the collection and retention of large fish.
As described above, in the underwater fish lamp according to the present embodiment, a bait space suitable for fish such as horse mackerel is an arrangement in the underwater space of a plurality of light portions having strong directivity and light light portions having appropriate intervals. It was found to be effective for collecting and retaining fish for a long time.
