  By the way, when an underwater fish lamp is thrown into the water, the underwater fish lamp rotates in the water due to a tide or the like. For this reason, the power cable connecting the water power source that is grounded on the ship or the like and the underwater fish collection lamp may be twisted, and the power cable may be damaged. Even if the power cable does not break, if the underwater fishing light rotates due to tidal currents, fish gathered around the underwater fishing light may escape, which may reduce the fish collection effect. It has become.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide an underwater fish collecting lamp that prevents the fish collecting effect from being reduced by stabilizing the posture in water.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments described below, members that are common to each other are denoted by the same reference numerals, and redundant descriptions thereof are omitted.

  FIG. 1 is a perspective view showing an underwater fish collection lamp 1 according to an embodiment of the present invention. FIG. 2 is a diagram showing an example of the usage state of the underwater fish lamp 1, and FIG. 3 is a plan view of the underwater fish lamp 1 as viewed from above. As shown in FIG. 2, the underwater fish collection lamp 1 is a fish collection lamp that is used by being put into the water from above the ship 100, for example, and is a device that collects fish by irradiating the surroundings with light. The underwater fish lamp 1 is connected to a surface power supply 110 provided on the ship 100 via a power cable 4 and emits light when power is supplied from the ship. The underwater fish lamp 1 is held at a predetermined depth by a chain 120 extending from the ship 100. However, the underwater fishing light 1 is not limited to the chain 120, and may be held in a state suspended in water by a wire or a rope.

  As shown in FIG. 1, the underwater fish lamp 1 includes a light source holding member 3 that holds and arranges a plurality of light source devices 2 in the circumferential direction. The light source holding member 3 has a frame structure in which, for example, a metal plate, an L-shaped angle, or the like is assembled in a substantially cylindrical three-dimensional shape, and the light source device 2 is attached to a plurality of locations on the side surface. In the present embodiment, for example, as shown in FIG. 3, the light source holding member 3 is formed so as to have a substantially square shape in plan view, and the light source device 2 is attached to each of the four side surfaces. The light source holding member 3 includes a hook-shaped engaging portion 11 at the upper end portion. The underwater fish lamp 1 is supported in a state of being suspended in water by engaging a chain, a wire, a rope, or the like with the engaging portion 11.

  The light source device 2 uses, for example, a light emitting element 30 such as an LED (Light Emitting Diode) as a light source. By using the LED as a light source, power consumption can be suppressed. The light source device 2 is provided with a plurality of light emitting elements 30. More specifically, the light source device 2 is configured as a thin plate-like light emitting plate in which a plurality of light emitting elements 30 are two-dimensionally arranged on a substrate. Each of the plurality of light source devices 2 attached to the light source holding member 3 is connected to the power cable 4 connected to the surface power source 110, emits light by supplying power from the surface, and irradiates light from the surface of the light emitting plate. Here, each light source device 2 is attached to each side surface of the light source holding member 3 with the surface side on which the plurality of light emitting elements 30 are mounted facing outward. Light is emitted outward from each of the two side surfaces.

  Each light source device 2 is detachably attached to the light source holding member 3. For example, by attaching the light source device 2 to the light source holding member 3 using a screw (not shown), the light source device 2 can be easily detached from the light source holding member 3 by removing the screw. As described above, the light source device 2 is detachably attached to the light source holding member 3 so that the light source device 2 can be removed from the light source holding member 3 to perform maintenance work or exchange. . Details of the light source device 2 will be described later.

  Further, the underwater fish lamp 1 includes a vertical ladder 5 that protrudes downward from the lower end of the light source holding member 3. FIG. 4 is a side view of the underwater fish collecting lamp 1. A flange portion 7 is provided at the lower end portion of the light source holding member 3 along the diagonal line of the lower surface. The vertical ladder 5 is fixed to the flange portion 7 with screws 8 and attached in a state of vertically protruding from the lower surface of the light source holding member 3. The vertical ladder 5 is a metal plate made of aluminum, stainless steel, or the like, for example, a rectangular plate as shown in FIG. One end of the vertical ladder 5 is provided at a substantially central position of the light source holding member 3, and the other end is extended to a predetermined position outside the light source holding member 3. In the underwater fish lamp 1, as shown in FIG. 3, the portion where the vertical ladder 5 protrudes in the plan view is the rear side, and the opposite portion is the front side.

  Here, the vertical ladder 5 is not necessarily rectangular. FIG. 5 is a diagram illustrating an example of the vertical ladder 5 having a shape different from that in FIG. 4. The vertical ladder 5 shown in FIG. 5 has a form in which the front side (B side shown in FIG. 5) is formed in a triangular shape and the rear side (A side shown in FIG. 5) is formed in a rectangular shape. The front end is fixed to the front side of the center position of the light source holding member 3, and the rear end is extended to a predetermined position outside the light source holding member 3 as in FIG. Yes. That is, if the vertical ladder 5 attached to the light source holding member 3 can make the area on the rear side larger than the area on the front side with reference to the center of gravity position (center position) of the light source holding member 3, Any shape may be used.

  Such a vertical ladder 5 exhibits the same action as a so-called weathercock. That is, as shown in FIG. 6, when a tidal current F <b> 1 in a certain direction acts on the underwater fish lamp 1, a moment to rotate the underwater fish lamp 1 acts on the vertical ladder 5. The vertical ladder 5 is stabilized in a posture in which the rear side that protrudes outside the light source holding member 3 faces the rear side of the tidal current F1. That is, the vertical ladder 5 has a function of stabilizing the posture of the underwater fishing lamp 1 with the front side of the underwater fishing lamp 1 facing the upstream side of the tidal current F1 and the rear side facing the downstream side of the tidal current F1. The underwater fish lamp 1 is prevented from rotating in the water. Thus, the underwater fish lamp 1 does not excessively twist the power cable 4 connected to the surface power supply 110 through the upper end of the light source holding member 3, and prevents the power cable 4 from being damaged due to the twist. be able to. In addition, since the rotation of the underwater fish collection lamp 1 can be reduced by the vertical ladder 5, the fish collected around the underwater fish collection lamp 1 is not missed. Therefore, the underwater fish collection lamp 1 can maintain a high fish collection effect.

  Further, the underwater fish lamp 1 may be provided with a side ladder 9 on the side surface of the light source holding member 3. FIG. 7 is a view showing the underwater fish lamp 1 to which the side ladder 9 can be attached. The underwater fish lamp 1 includes a plate-like support member 40 to which a side ladder 9 can be attached on both left and right side surfaces. The support member 40 is fixed to the left and right side surfaces of the light source holding member 3 by, for example, welding. The support member 40 has a fixing hole 41 for mounting and fixing the screw 48 and a long hole 42 opened in an arc shape with a predetermined radius centered on the fixing hole 41. On the other hand, the side ladder 9 attached to the support member 40 includes a mounting plate 45 configured by bending an end portion of a flat ladder main body at a substantially right angle. The mounting plate 45 is formed with a pair of holes 46 and 47 that are opened at an interval equal to the radius of the fixed hole 41 and the long hole 42. The side ladder 9 can be fixed to the side surface of the light source holding member 3 by inserting the screw 48 into the hole 47 and the fixing hole 41 and fixing the screw 48, and the hole 46 and the long hole 42. The side ladder 9 can be adjusted to a predetermined angle by inserting the screw 48 and fixing the screw 48.

  FIG. 8 is a diagram for explaining the function and effect of the side ladder 9. As shown in FIG. 8 (a), the side ladder 9 can adjust the mounting angle θ within the range in which the arc-shaped long hole 42 is formed with the fixing hole 41 as the center of rotation. The side ladder 9 can be disposed in a state where the side ladder 9 is inclined downward toward the front side, or can be disposed in a state where the side surface ladder 9 is inclined upward. It is also possible to arrange the side ladder 9 in a substantially horizontal state with respect to the side surface of the light source holding member 3.

  FIG. 8A shows an angle adjustment example in a state in which the side ladder 9 is inclined downward toward the front side of the underwater fish collection lamp 1. When the side ladder 9 is tilted downward toward the front side of the underwater fish lamp 1 as described above, when the tidal current F1 acts from the front side of the underwater fish lamp 1 as shown in FIG. The tidal current F1 generates a force in the direction of sinking the underwater fish lamp 1 downward as indicated by an arrow F2, and the underwater fish lamp 1 can be submerged to a predetermined depth. On the other hand, when the side ladder 9 is tilted upward toward the front side of the underwater fish lamp 1, when the tidal current F1 is received, a force that causes the underwater fish lamp 1 to rise upward is generated. As described above, the underwater fish collection lamp 1 includes the side ladder 9 that can adjust the attachment angle θ, so that the vertical position of the underwater fish collection lamp 1 in the water can be stabilized according to the attachment angle θ. Become.

  As described above, the underwater fish collection lamp 1 can stabilize the posture in the rotation direction in the water by including the vertical ladder 5, and can also be vertically adjusted in the water by including the pair of side ladders 9 protruding laterally with respect to the left and right side surfaces. It is the structure which can stabilize the position of a direction.

  Next, details of the light source device 2 will be described. FIG. 9 is a diagram illustrating a configuration example of the light source device 2. The light source device 2 includes a substrate 31 on which a plurality of light emitting elements 30 are mounted, a power cable 4 connected to the substrate 31, a substrate container 50, a filler 55, and a plate member 54. . The substrate container 50 has a concave portion 51 for accommodating the substrate 31 in the center, and a groove 53 through which the power cable 4 covered with vinyl chloride or the like passes is formed in a part of the peripheral wall portion 52 around the concave portion 51. This is the configuration. Here, the depth of the recess 51 is formed to be slightly larger than the thickness of the substrate 31 on which the light emitting element 30 is mounted. The plate member 54 is configured as, for example, a transparent body that transmits light from the light emitting element 30, has an outer shape that is substantially the same size as the substrate container 50, and an edge thereof is joined to the peripheral wall portion 52 of the substrate container 50. As a result, the recess 51 is sealed. The plate member 54 may be a translucent body, but is preferably configured as a transparent body from the viewpoint of improving the utilization efficiency of light emitted from the light emitting element 30. Further, the plate member 54 may be made of resin, but it is preferable that the plate member 54 is made of glass in consideration of hard use that is repeatedly introduced into water, and more preferably than ordinary glass. The use of tempered glass with high strength.

  The plurality of light emitting elements 30 are mounted in a two-dimensional array with respect to the surface of the substrate 31. The power cable 4 is electrically connected to a connection portion 32 made of a conductor provided on the surface side of the substrate 31. And the board | substrate 31 with which the light emitting element 30 was mounted is arrange | positioned with respect to the recessed part 51 of the board | substrate container 50, as shown to Fig.9 (a). At this time, the power cable 4 is not wired at the shortest distance from the inner side of the recess 51 to the groove 53, but, for example, is wired so as to be wound around the substrate 31 at least once in the space inside the recess 51. Then, the wiring is routed outside the substrate container 50 through the groove 53.

  Then, the filling material 55 is filled inside the recess 51 and inside the groove 53 in a state where the substrate 31 and the power cable 4 are accommodated inside the recess 51. The filler 55 is made of, for example, resin or silicon, and has a certain viscosity and fluidity when filled, and enters the gap around the substrate 31 or the gap around the power cable 4 inside the recess 51. Thus, the inner space of the recess 51 is filled without any gap. The filler 55 may be one that loses fluidity and solidifies after filling, or one that does not lose viscosity and fluidity. The filler 55 filled in the surface of the substrate 31 may be different from the filler filled around the substrate 31. However, it is preferable that the filler filled in at least the surface of the substrate 31 has transparency that allows light to pass after filling.

  Then, after the filler 55 is filled into the inner space of the recess 51, the plate member 54 is bonded to the peripheral wall portion 52 of the substrate container 50. At this time, the plate member 54 and the substrate container 50 are bonded so that bubbles are not generated in the inner space of the recess 51 sealed by the plate member 54. In this manner, the light source device 2 is configured as a light emitting plate that irradiates light outward from one surface on which the plate member 54 is provided, as shown in FIG. 9B.

  FIG. 10 is a diagram illustrating a cross-sectional structure of the light source device 2. As shown in FIG. 10, the light source device 2 includes a filler with respect to the periphery of the substrate 31, the light emitting element 30, and the power cable 4 in a state where the inner space of the recess 51 in which the substrate 31 is accommodated is sealed by the plate member 54. 55 is configured so that no bubbles or air layers exist in the sealed space. Therefore, even if the underwater fish lamp 1 is thrown into the water, the light source device 2 is not affected by the water pressure. That is, the water pressure acting on the light source device 2 increases by 1 atm for every 10 m of water depth, such as 1 atm on the surface of the water, 2 atm at the depth of 10 m, 3 atm at the depth of 20 m, and 4 atm at the depth of 30 m. For example, when 4 atmospheres acts on the light source device 2 at a water depth of 30 m, if there are bubbles or air layers inside the light source device 2, the volume of the bubbles or air layers is compressed to ¼ by water pressure. Therefore, if bubbles or air layers exist inside the light source device 2, a large dent is generated in the outer wall portion of the light source device 2 as the water depth of the underwater fishing lamp 1 increases, and the dent causes the light emitting element 30 and the substrate 31 to be formed. It becomes a factor which damages by pressing. On the other hand, as shown in FIG. 10, when there is no bubble or air layer in the inner space of the light source device 2, the outer wall portion of the light source device 2 has a dent even if water pressure acts on the light source device 2. Does not occur. Therefore, even when the underwater fish lamp 1 is inserted deeply into the water, it can be used normally without damaging the light source device 2.

  The light source device 2 as described above is attached to the side surface of the light source holding member 3 with the groove 53 into which the power cable 4 is inserted facing upward, for example. Here, the filling material 55 is also filled in the gap around the power cable 4 in the portion of the substrate container 50 where the groove 53 is formed. However, the filler 55 is not necessarily in close contact with the outer peripheral surface of the power cable 4, and a fine gap may be formed between the filler 55 and the power cable 4. In such a case, when the underwater fish lamp 1 is thrown into the water, a capillary phenomenon occurs in a slight gap between the power cable 4 and the filler 55, and moisture moves along the power cable 4 inside the light source device 2. Infiltrate. When moisture entering due to capillary action reaches the connection portion 32 made of a conductor provided on the surface of the substrate 31, corrosion due to moisture starts and the light source device 2 is damaged. In particular, when the underwater fish lamp 1 is thrown into the sea, there is a problem that the conductor is remarkably corroded by the salt contained in the sea water and the light source device 2 cannot be used at an early stage.

  On the other hand, moisture that penetrates into the slight gap between the power cable 4 and the filler 55 by capillary action has a property of proceeding downward according to gravity. In the present embodiment, as described above, the power cable 4 is wired so as to be wound around the substrate 31 at least once inside the substrate container 50, and from the groove 53 of the substrate container 50 to the substrate 31. As a wiring pattern directed to the connection portion 32, a wiring portion that extends at least from the bottom to the top in a sealed space formed by the substrate container 50 and the plate member 54 is provided. The wiring portion extending from the bottom to the top serves as a resistance when the moisture that has entered through the capillary phenomenon proceeds, and therefore prevents the moisture from reaching the connection portion 32 provided on the surface of the substrate 31.

  Here, the wiring pattern of the power cable 4 in the light source device 2 is not necessarily limited to the pattern that winds around the substrate 31. In other words, in order to prevent water from entering due to capillary action, the wiring pattern from the groove 53 of the substrate container 50 to the connection portion 32 of the substrate 31 may have at least a wiring portion that extends from the bottom to the top. FIG. 11 is a diagram illustrating a wiring pattern example of the power cable 4 inside the substrate container 50.

  FIG. 11A shows a wiring pattern in a state where the periphery of the substrate 31 is wound once as described above. When the light source device 2 is arranged with the groove 53 of the substrate container 50 facing upward, a wiring portion 59 is formed on the right side of the substrate 31 from the bottom to the top. For this reason, the wiring portion 59 becomes a resistance that hinders the rise of moisture, and thus corrosion of the substrate 31 and the like can be prevented.

  FIG. 11B is an example of a wiring pattern of the power cable 4 when the groove 53 of the substrate container 50 is disposed facing downward. In the wiring pattern shown in FIG. 11B, the power cable 4 led from the lower part of the light source device 2 to the inside of the light source device 2 is wired upward and is connected to the connection part 32 at the upper part of the substrate 31. A wiring portion 59 is formed from the groove 53 toward the connection portion 32 from the bottom to the top. For this reason, the wiring portion 59 becomes a resistance that hinders the rise of moisture, and thus corrosion of the substrate 31 and the like can be prevented.

  FIG. 11C shows an example of a wiring pattern in which a plurality of power cables 4 are folded back inside the substrate container 50. In the wiring pattern shown in FIG. 11C, a plurality of power cables 4 are folded back inside the substrate container 50, and wiring portions 59 are formed at a plurality of locations from the bottom to the top. Therefore, in this wiring pattern, the length of the wiring portion 59 from the bottom to the top can be made longer than the wiring pattern shown in FIGS. 11A and 11B, and moisture that infiltrates by capillary action. Can be further reduced to reach the connecting portion 32. Therefore, as shown in FIG. 11C, a wiring pattern in which a plurality of power cables 4 are folded back inside the substrate container 50 is the most preferable pattern.

  Since the light source device 2 as described above is not affected by water pressure and has a low possibility of corrosion, a light source that can be used satisfactorily over a long period of time is realized. Therefore, the underwater fish lamp 1 equipped with such a light source device 2 is excellent in that the maintenance cycle is long and the running cost can be kept low.

  As shown in FIG. 1, the underwater fish lamp 1 of the present embodiment can have a light scattering device 6 attached to the front side of each light source device 2. The light scattering device 6 is configured, for example, as a box-shaped transparent container 20, and is slid and inserted from above into a guide portion 10 configured with L-shaped angles provided on the left and right sides of the light source device 2. 2 is attached to the front position. In this case, in the light scattering device 6, the left and right side edges of the transparent container 20 are held in the vertical direction by the L-shaped angle of the light source holding member 3 as indicated by a broken line in FIG. 3. In addition, the light scattering device 6 is dropped from the light source holding member 3 in water by holding the bottom portion of the transparent container 20 by the light source holding member 3 and closing the upper end portion of the guide portion 10 after inserting the slide. It is configured so that there is no.

  The light scattering device 6 includes a plurality of openings 21 and 22 that are formed in a mesh shape in order to introduce or derive a water flow at the upper and lower ends of the transparent container 20. Furthermore, the light scattering device 6 includes a reflecting member 23 formed in a size larger than the openings 21 and 22 inside the transparent container 20. The reflecting member 23 is formed in a thin and lightweight plate shape, and is configured by a glossy member whose surface reflects light. Such a reflection member 23 may be constituted by a glossy metal plate, or may be a plate in which a glossy metal is plated on the surface of the resin plate. The shape of the reflecting member 23 may be any shape such as a round shape or a square shape. For example, if the shape of the reflecting member 23 is formed in the shape of an elongated tree, light reflection that mimics a small fish can be realized.

  FIG. 12 is an enlarged view of the light scattering device 6. When the light scattering device 6 is thrown into water in a state of being attached to the front side of each light source device 2, the openings 21 and 22 provided at the upper end portion and the lower end portion of the transparent container 20 are changed to arrows F 3 and F 4. Inject the water stream as shown. Since this water flow changes depending on the tide around the underwater fishing light 1, a water flow corresponding to the surrounding tide is generated inside the light scattering device 6. And the water flow which arises inside the light-scattering apparatus 6 makes the reflection member 23 accommodated inside the transparent container 20 flow. That is, the reflecting member 23 changes its position or posture in the transparent container 20 by the water flow flowing from the upper end portion and the lower end portion of the light scattering device 6, and light emitted from the light source device 2 according to the position or posture. Is scattered to the surroundings. Accordingly, since the light reflected by the reflecting member 23 is scattered to the surroundings as if small fish are gathered around the underwater fishing light 1, it has the effect of collecting relatively large fish and bandits. It becomes possible to raise it further.

  Such a light scattering device 6 is detachable from the light source holding member 3. Therefore, the light scattering device 6 in which the reflecting members 23 having different sizes or shapes depending on the type of fish aiming at the fish collecting effect can be mounted on the light source holding member 3. When the light scattering device 6 is unnecessary, the underwater fish collecting lamp 1 can be used with the light scattering device 6 removed from the light source holding member 3. In addition, the transparent container 20 which comprises the light-scattering apparatus 6 is not necessarily restricted to a box shape, You may be a cylinder shape.

  As mentioned above, although one Embodiment regarding this invention was described, this invention is not restricted to the thing of the content mentioned above, A various modification is applicable.

  For example, in the above embodiment, the case where the power cable 4 is directly connected to the light source device 2 from the surface power supply 110 is illustrated, but the present invention is not limited to this. That is, when replacing the light source device 2 is considered, the power cable 4 connected to the water power source 110 and the power cable 4 connected to the light source device 2 are configured as separate cables, and the two power cables 4 are connected to each other. More preferably, a waterproof connector is used to connect each other. In this case, when the light source device 2 is replaced, it is possible to replace only one of the plurality of light source devices 2 by removing the waterproof connector, so that excellent convenience is exhibited.

  Further, for example, the plurality of light source devices 2 attached to the side surface of the light source holding member 3 may be configured to irradiate light having different wavelengths (colors). For example, by using two light source devices 2 that emit white light and two light source devices 2 that emit blue light, the fish collection effect can be further enhanced.
