Description

  The present invention relates to a fishing light used by being attached to a fishing boat, and in particular, an LED fishing light is used for the fishing light, and a cooling liquid for cooling the LED collecting light is released to the outside air through a heat radiation hose. The present invention relates to a wire hanging type LED fishing light.

  Currently, panel-type LED fishing lights (a large number of low-capacity cannonball-type LED elements, etc.) have been experimentally installed on fishing boats, and their effects have been verified. Not reached. The reason for this is that the low-capacity LED elements are arranged side by side, so it is dark for the total capacity (electric power), the ability to collect fish is weak, and because it is a panel type, there is a light / dark boundary on the light irradiation surface against the sea surface. it can. In addition, a projector type (air-cooled type) has been tried, but it is air-cooled and heavy (because a heat-dissipating fin is required). Panel type LED, projector type, both size and weight due to the structure of its technical features This is a fixed type.

JP2015-170590

In this fixed type, because the ship fluctuates during operation, the light sways up and down, the intensity of light is strongly projected on the sea surface, and the gathered fish scatter (distant from the vicinity of the ship) squid fishing Since single fishing (representative fishing method) is a fishing method that is directly under the boat, collecting a school of fish directly under the boat determines the success or failure of the catch.
For this reason, the metal halide fishing lights currently used on most fishing boats are a wire suspension system that stabilizes the surface illuminance to some extent even when the boats shake.
The most important point of the fishing light is the light distribution around the ship that irradiates strong light far away, does not create a light boundary on the sea surface, and does not produce strong or weak light.

  By the way, in the “wire-suspended LED fishing light” disclosed in Japanese Patent Application Laid-Open No. 2015-170590, the size of the light emitting portion of the LED fishing light that uses the LED element as a light source does not exceed approximately 150 mm × 150 mm. Therefore, in order to cool the cooling water for cooling the LED fishing light, a cooling device (heat exchanger) is required, and as a result, a large generator for driving the cooling device is required.

  In view of the problems as described above, the present invention was created to solve the problems, and the object of the invention is to reduce the weight of the LED fishing light and make it possible to hang it on a wire rope. A small generator that eliminates the need for a cooling device that cools the coolant and eliminates the need for a large generator to drive the cooling device by releasing heat from the cooling fluid that cools the LED fishing light to the outside air through the heat radiation hose. It is providing the wire hanging type LED fish-collecting light which can be used.

To achieve the above object, the present invention is the size and the LED light emitting device of the following COB structure 100 mm × 100 mm, multiple upward and downward becomes the material from aluminum member said LED device is mounted on the surface A light-radiating member having a light-radiating member integrally formed with a rectangular heat-dissipating path with a corner-inclined section that repeats the bending of 180 degrees , and flows in the heat-dissipating path of the heat-dissipating member. A cooling liquid that absorbs heat generated by the LED light emitting device through a peripheral wall surface and cools the LED light emitting device, and that allows the heat of the cooling liquid to be released to the outside air while the cooling liquid that has absorbed heat flows inside. comprising a Do radiator hose to form an inlet and outlet of the heat radiation path on both sides of the upper end of each side or dissipating member at the lower end of the heat dissipation member, a cylindrical side peripheral surface of the heat dissipation hose, rigid It is composed of a soft side peripheral surface in which the material is integrated and spirally wound, and both ends of the radiating hose are connected to the inlet and outlet of the radiating path formed in the radiating member of the LED fishing light. The radiating hose is circulated on the fishing boat and connected to the fishing boat, and the cooling liquid storage tank and the circulation pump are provided in the middle of the circulated radiating hose, and the bow side and the stern on the fishing boat are provided. The LED fishing light is suspended in a swingable manner between wire ropes attached between poles attached to the sides, and the cooling fluid circulates through the inside and is attached to the wire ropes stretched on a fishing boat. The LED light-emitting device can be cooled through a heat dissipating hose.

According to the wire hanging type LED fishing light according to the present invention, by using an LED light emitting device having a COB structure of 100 mm × 100 mm or less, a cooling device for cooling the cooling liquid can be eliminated, and the cooling device can be used. A large generator to be driven is not required, and a small generator can be used. Furthermore, since the installation space for the cooling device and the large generator can be eliminated, in particular, the merit contributing to the small ship can be significantly improved.
Moreover, since the heat radiating member to which the LED light emitting device is attached is made of a lightweight aluminum member, the LED fishing light having the LED light emitting device and the heat radiating member can be reduced in weight. The LED fishlight can be suspended in a swingable manner on a wire rope that suspends a metal halide fishlight that is installed.
Furthermore, since the cross section of the heat dissipating path that is formed integrally inside the heat dissipating member and repeats a plurality of reciprocations is formed into a square with a cross section inclined at the corner, the cooling water flowing inside the heat dissipating path is Because it flows down in close contact with the entire inner peripheral surface of the rectangular section of the corner, it is possible to absorb heat from the entire inner peripheral surface of the heat dissipation path, and the heat exchange between the heat dissipation member and the coolant. The rate can be increased.
In addition, since the cylindrical side peripheral surface of the heat-dissipating hose is composed of a soft side peripheral surface in which a hard wire integrated therein is spirally wound, flexibility is maintained by the cylindrical soft side peripheral surface. In addition, the cylindrical shape is maintained by the spiral hard wire integrated therein, and the hard wire 6b is spiral, so that it can be easily bent and can maintain flexibility. . In addition, the use of a flexible hose makes it possible to easily change the position of the fish collection lamp, and to provide the most suitable light distribution according to the target fish depending on the season.
In addition, by attaching a wide-angle lens or an umbrella-type reflector to the LED light-emitting device, it is possible to achieve a very new and beneficial effect, such as the ability to exhibit the maximum fish collection ability while maintaining a more stable light distribution sea level illuminance. It is what you play.

It is an experiment figure which shows the temperature of a LED light emission part.

  Hereinafter, the present invention will be described more specifically based on embodiments for carrying out the invention described in the drawings.

  In the figure, a wire-suspended LED fishing light is used by attaching a light source that emits light to be used for collecting fish in the nighttime fishery using the habit of gathering in the light of fish. 3 and the LED light collecting lamp 2 having the heat radiating member 4 attached to the surface thereof, the cooling liquid 5 for cooling the LED light emitting apparatus 3, the heat radiation hose 6 through which the cooling liquid 5 flows, and the storage tank for the cooling liquid 5 7. A circulation pump 8 or the like is provided, and the LED fishing light 2 is suspended swingably on a wire rope 9 stretched on the fishing boat 1, and the cooling liquid 5 circulates through the heat-dissipating hose 6 flowing through the inside. The LED light emitting device 3 has a feature that enables cooling.

  The LED fishing light 2 is a light source that emits light used to collect fish in night fishing, and includes an LED light emitting device 3 and a heat radiating member 4 to which the LED light emitting device 3 is attached. The LED light-emitting device 3 generates heat by emitting light, and unless the heat is removed, the light emission amount of the LED gradually decreases due to the heat. For this reason, it is necessary to release the heat by the heat radiating member 4.

  Among these, LED light-emitting device 3 uses LED for the light source which emits light directly. The LED uses a light emitting diode and has features such as low power consumption, long life, and low heat generation. Since the LED light-emitting device 3 uses an LED as a light source, it consumes less power than when a conventional heating lamp is used as a fish collection lamp. For this reason, a generator can be made small and power generation energy can also be reduced.

  The LED light emitting device 3 of the present invention has a COB structure with a size of 100 mm × 100 mm or less. The LED light emitting device 3 having a COB structure is a planar light emitting device that irradiates planar light by arranging a plurality of LED light emitting elements in a matrix. The reason why the size is limited to 100 mm × 100 mm or less is that when the size is larger than this, the cooling liquid 5 that is a feature of the present invention cannot be completely cooled by using only the heat dissipating hose 6. .

  That is, when the size of the LED light emitting device 3 exceeds 100 mm × 100 mm, the cooling liquid 5 cannot be sufficiently cooled only by the heat radiating hose 6, and as a result, the uncooled cooling liquid 5 sufficiently covers the central portion of the LED. Can not be cooled down. This is because a portion of the central portion of the LED light emitting device 3 that is not cooled cannot emit a predetermined amount of light and becomes dim, so that the function as a fish collecting light cannot be fully exhibited.

  If a cooling device that cools the LED light emitting device 3 is used separately as in the conventional case, it can be cooled even if the size exceeds 100 mm × 100 mm. However, in that case, the cooling cost increases remarkably, A large generator for cooling is also required, and the energy cost increases. In addition, the installation space for such various new devices, an increase in cost, and an environment that is difficult to be adopted for the small fishing boat 1 are obtained.

  On the other hand, in the present invention, by using the LED light emitting device 3 having a size of 100 mm × 100 mm or less, a cooling device for cooling the coolant 5 can be made unnecessary, and a large-size driving device is driven. Small generators can be used without a generator. Furthermore, since the installation space for the cooling device and the large generator can be eliminated, in particular, the merit contributing to the small fishing boat 1 is significantly improved.

  In the LED light emitting device 3 of the present invention, the LED has a COB structure. An LED light-emitting device having a COB structure has an LED light-emitting element mounted in a predetermined mounting area of a substrate, and the electrode of the light-emitting element is electrically connected to a lead electrode (inner lead) on the substrate by wire bonding or the like. The LED light emitting element is manufactured by connecting the LED light emitting element to the lead electrode by flip chip mounting and sealing the mounting region with a sealing member such as a translucent resin so as to cover the LED light emitting element and the bonding wire. The LED light-emitting device having a COB structure is excellent as a planar light-emitting device that irradiates planar light by arranging a plurality of LED light-emitting elements in a matrix.

  In addition, at least one lens 31 is combined and attached to the LED light-emitting device 3 so as to cover the entire light emitted from the LED light-emitting device 3. Further, an umbrella-shaped reflector 32 that collects and reflects light emitted from the LED light-emitting device 3 is attached to the LED light-emitting device 3.

  The LED light emitting device 3 is attached to the surface of the heat dissipating member 4. The heat radiating member 4 is made of an aluminum member. Aluminum has the highest thermal conductivity after copper among the major metals. The specific gravity of aluminum is as light as about 30% of copper, and it is not easily rusted. Copper is superior to aluminum from the viewpoint of thermal conductivity, but on the other hand, it is three times heavier and more susceptible to rusting, and it is difficult to hang on a wire rope on fishing boat 1 for use. In that respect, aluminum has a high thermal conductivity, is light and resistant to rust, and is suitable for use in the ocean suspended from a wire rope stretched on a fishing boat 1. The heat radiating member 4 has a thick square shape.

  A heat radiating path 41 through which the coolant 5 flows is integrally formed inside the heat radiating member 4 with a large thickness. While the coolant 5 flows through the heat radiation path 41, the cooling liquid 5 absorbs heat generated in the LED light emitting device 3 through the inner peripheral wall surface of the heat radiation path 41, thereby cooling the LED light emitting device 3. For this reason, the heat radiation path 41 has a certain length and a cross-sectional shape that easily absorbs the LED light emitting device 3 transmitted from the surface of the heat radiation member 4 through its inner peripheral wall surface.

  The heat radiation path 41 is formed in a square cross-sectional shape that repeats a plurality of reciprocations so as to easily absorb heat from the LED light emitting device 3 efficiently. The illustrated heat radiation path 41 is formed in a state where the inlet 42 and the outlet 43 protrude slightly downward on both sides of the lower end of the rectangular heat radiating member 4. One end of the heat radiating hose 6 is connected to the inlet 42 and the outlet 43, respectively.

  The heat radiating path 41 extends vertically upward from the inlet 42 at the lower end of the heat radiating member 4, folds 180 degrees at a predetermined position on the upper portion, and extends vertically downward on the inside of the heat radiating member 4, with a predetermined lower portion. The portion of the heat radiating member 4 is again extended upward and perpendicularly by turning back 180 degrees at the point. In the drawings of the embodiments, the heat radiation path 41 is repeated three times at a predetermined upper portion and twice at a predetermined lower portion. The downstream side of the heat radiation path 41 finally extends vertically downward and is connected to the discharge port 43.

  In addition, in the figure of the Example, although the case where the inflow port 42 and the discharge port 43 were formed in the both sides of the lower end of the thermal radiation member 4 was demonstrated, the direction of the thermal radiation path 41 formed in the inside of the thermal radiation path 41 is up-down May be reversed. That is, the inlet 42 and the outlet 43 may be formed on both sides of the upper end of the heat radiating member 4.

  As the shape of the cross section of the heat radiation path 41, it is formed in a square cross section of a corner slope 41a in which each corner of the square cross section is an inclined surface. In the case of a square cross section, it is difficult for the coolant 5 flowing through the inside to flow to every corner of a right-angled corner, and a gap where the flowing coolant 5 does not easily flow is likely to occur at a part of the corner. As a result, it is difficult to release heat on the entire circumferential surface including the corners in the case of a square cross section.

  On the other hand, in the cross-sectional quadrilateral of the corner slope 41a, the corner where the void is likely to be formed in the cross-sectional quadrilateral is an inclined surface. Compared with the heat release function. Note that the cross-sectional circle has a minimum circumference compared to the cross-sectional area, and the heat release efficiency is inferior to that of the cross-sectional square of the corner slope 41a.

  The coolant 5 functions to cool the LED light emitting device 3 by flowing through the heat radiation path 41 of the heat radiating member 4 and absorbing heat generated in the LED light emitting device 3 through the inner peripheral wall surface of the heat radiation path 41. The coolant 5 is, for example, water that is safe and does not cost much, but may be, for example, edible oil having a specific heat smaller than that of water and higher safety.

  The heat dissipating hose 6 has a flexible structure having a function of releasing the heat of the cooling liquid 5 to the outside air while the cooling liquid 5 that has absorbed heat flows inside. The heat dissipating hose 6 has a flexible structure and is flexible, so that it is excellent in workability, increases the degree of freedom when being arranged on the fishing boat 1, and can be easily attached to the wire rope 9.

  The heat dissipating hose 6 is formed of a cylindrical soft side peripheral surface 6a made of a soft synthetic resin. Inside the soft synthetic resin that is the material of the soft side peripheral surface 6a, a hard wire made of an elongated hard synthetic resin is used. 6b is spirally wound and integrated.

  The heat-dissipating hose 6 is kept flexible by a cylindrical soft side peripheral surface 6a, and a cylindrical shape is maintained by a helical hard wire 6b integrated therein. Moreover, since the hard wire 6b is spiral, it bends easily. For example, soft polyvinyl chloride (soft PVC) is used as the soft synthetic resin forming the soft side peripheral surface 6a. Further, for example, hard polyvinyl chloride (hard PVC) is used as the hard synthetic resin forming the spiral hard wire 6b.

  The heat dissipating hose 6 is connected to the inlet 42 and the outlet 43 of the heat dissipating path 41 formed in the heat dissipating member 4 of the LED fishing light 2 and is circulated on the fishing boat 1. That is, one end of the heat dissipating hose 6 is connected to the inflow port 42, the other end of the heat dissipating hose 6 is connected to the discharge port 43, and the heat dissipating hoses 6 other than both ends are circulated on the fishing boat 1. ing.

  A storage tank 7 for the coolant 5 and a circulation pump 8 are provided in the middle of a heat dissipating hose 6 circulated on the fishing boat 1. The storage tank 7 and the circulation pump 8 are installed on the fishing boat 1. The storage tank 7 is a tank that temporarily stores the coolant 5. The circulation pump 8 is a pump for circulating the coolant 5 between the storage tank 7 and the heat radiation path 41 of the LED light emitting device 3 through the heat radiation hose 6. The coolant 5 is cooled while circulating through the heat radiating hose 6.

  On the fishing boat 1, a wire rope 9 is stretched in the length direction of the boat. Pole 91 and 92 are attached to the cockpit on the bow side and the stern side of the fishing boat 1, and the wire rope 9 is stretched between the pole 91 and the pole 92. A heat radiation hose 6 connected at both ends to the heat radiation path 41 of the LED light emitting device 3 is attached to the wire rope 9 stretched between the pole 91 and the pole 92.

Similarly, the LED fishing light 2 is suspended from the wire rope 9 so as to be swingable between the pole 91 and the pole 92. The LED fishing light 2 is suspended so as to emit light toward the port side and starboard direction of the fishing boat 1. The LED fishing light 2 is suspended on the wire rope 9 so as to be able to swing, so that even if the fishing boat 1 is tilted by a wave, the LED fishing light 2 swings and maintains a predetermined orientation with respect to the sea surface. The light emitted from the LED fishing light 2 always illuminates the sea surface of the fishing boat 1 in the port and starboard directions.

Next, the operation based on the configuration of the embodiment for carrying out the invention will be described below.
The LED fishing light 2 attached to the fishing boat 1 is stretched between the pole 91 and the pole 92 and is suspended from the wire rope 9 so as to be swingable. Therefore, even if the fishing boat 1 swings left and right, the LED fishing light 2 2 can always illuminate the sea surface in the port and starboard directions without tilting left and right.

  The LED fishing light 2 that illuminates the sea surface generates heat when it emits light from the LED light emitting device 3 on its surface. Since the heat radiating member 4 is attached to the back side of the LED light emitting device 3, the heat generated in the LED light emitting device 3 is removed by being transmitted to the heat radiating member 4, and the LED light emitting device 3 is prevented from being heated. Therefore, a decrease in the light emission amount is avoided.

  The heat transmitted to the heat radiating member 4 is absorbed by the coolant 5 flowing through the heat radiating path 41 inside. The coolant 5 is circulated by the circulation pump 8 so that it flows in the order of the storage tank 7, the upstream heat radiation hose 6, the heat radiation member 4, and the downstream heat radiation hose 6 and returns to the original storage tank 7. ing.

  The coolant 5 that absorbs heat from the heat radiating member 4 enters from the inlet 42 of the heat radiating path 41 inside the heat radiating member 4, flows through the heat radiating path 41, and is discharged from the outlet 43. Since the heat radiation path 41 through which the coolant 5 flows is formed in a square shape with a corner slope 41a, the coolant 5 is in close contact with the inner peripheral wall surface of the heat radiation path 41 having a square shape with a corner slope 41a. It flows in the state. Thereby, the coolant 5 can efficiently absorb heat from the entire inner peripheral wall surface of the heat radiation path 41.

  In this way, the heat generated in the LED light emitting device 3 when the sea surface is illuminated is transferred to the heat radiating member 4, and the heat transferred to the heat radiating member 4 is transferred to the cooling liquid 5 flowing through the heat radiating path 41 and absorbed therein. This prevents the LED light emitting device 3 from being heated.

  The coolant 5 that is heated by absorbing heat while flowing through the heat radiation path 41 of the heat radiation member 4 flows from the discharge port 43 of the heat radiation path 41 into the heat radiation hose 6 to which the end is connected. . The coolant 5 that has flowed into the heat radiating hose 6 is cooled by the absorbed heat being released from the surface of the heat radiating hose 6 to the outside air while flowing through the inside.

  The coolant 5 from which heat has been released while flowing through the heat radiating hose 6 is once stored in the storage tank 7 and then flows again through the heat radiating hose 6 toward the inlet 42 of the heat radiating path 41 of the heat radiating member 4. Flowing. While flowing through the heat radiation hose 6, the heat absorbed by the coolant 5 is released from the surface of the heat radiation hose 6 to the outside air.

  That is, the coolant 5 flows while flowing through both the so-called upstream heat-dissipating hose 6 flowing toward the heat-dissipating member 4 and the so-called downstream heat-dissipating hose 6 discharged from the heat-dissipating member 4 and flowing. Heat is released from the surface to the outside air.

  In this way, the heat generated in the LED light emitting device 3 when illuminating the sea surface is transmitted to the coolant 5 through the heat radiating member 4. The heat transmitted to the coolant 5 is released to the outside air from the surface of the heat radiation hose 6 while flowing through the heat radiation hose 6, whereby the LED light emitting device 3 is cooled and a decrease in the light emission amount is prevented. It is.

  Since it was found that the simple cooling system shown in FIG. 2 was sufficient for cooling, an experiment for confirming the temperature rise was conducted in the factory. As shown in FIG. 8, it was observed that the result increased from the room temperature of 20 ° C., but saturated at 42 to 43 ° C. As a result, it was found that the maximum temperature rise from the outside air temperature was about 25 ° C., and that it could be sufficiently cooled even in summer (outside air temperature 30 ° C.).
