Description

The present invention relates to a fish collection system, and more particularly to a fish collection system using light emitting diodes.

Usually, in order to catch squid and sword fish effectively, a fishing light that attracts target fish species is widely used.
At present, the cost of the generator that turns on the fishing light of the fishing boat in the squid fishing fishery accounts for 60% or more of the total cost of operation, and 40% or more of the total operating cost including the replacement cost of the fishlight. The greater the share, the greater the burden. In recent years, crude oil prices have hindered fishery management.
Most metal halide lamps are used as squid fish lamps.
However, metal halide lamps usually require very large power consumption of about 1 KW to 3 KW, so power consumption is high, and the temperature of the glass surface during light emission is very high, which may cause fire or burns. There is a disadvantage that the lifetime is as short as about 3,000 hours. In addition, when a metal halide lamp is used for about 4 to 5 months, the fish collection performance must be reduced and replaced, and a ballast that is heavy and has a large volume is required. There is a disadvantage that the volume of the fish hold for storing the fish decreases due to the increase in the space occupied by such additional equipment.
Furthermore, since the light from the metal halide lamp is radiated in all directions through the glass sphere, the sky and deck are illuminated in addition to the irradiation range necessary for fish collection, and 60 to 70% or more of the total light quantity is unnecessarily consumed. In addition, since light from the infrared region to a part of the ultraviolet region is emitted from the metal halide lamp, light other than light in an efficient wavelength band is also emitted for the fish to be collected, such as squid fish. The use of light for efficient fish collection was inefficient.
On the other hand, blue wavelength light is effective for collecting squid fish and has a longer depth of penetration into seawater than other wavelengths. Compared with other lighting, there is a disadvantage that the worker's fatigue is increased and the operation efficiency is lowered.

The present invention has been devised in order to improve the above-described problems. By using a light-emitting diode, light of an efficient wavelength is provided to a fish collection target fish by limiting the light emission angle. The purpose of the present invention is to provide a fish collection system capable of improving not only the use of light and the efficiency of fish collection but also the work efficiency of workers.

1 and 2, the fish collection system 10 includes a support base 12, first and second support lines 21 and 22, a support bar 30, a first fish collection lamp 100a, and a second fish collection lamp 100b.
The support device includes a support base 12, first and second support lines 21 and 22, and a support bar 30.
The support bases 12 are installed apart from each other on the ship 50.
The first support line 21 connects between the support bases 12.
The second support line 22 connects the support bases 12 at a position higher than the first support line 21.
The first and second support wires 21 and 22 are preferably iron wires that can support the plurality of first and second fish collection lamps 100a and 100b.
The support bar 30 connects the first and second support lines 21 and 22 in a direction across the first and second support lines 21 and 22, that is, in a vertical direction.
A plurality of the first fishlight lamps 100a are mounted in a row in the horizontal direction between the support bars 30, and the second fishlight lamps 100b are arranged in a row at a position higher than the first fishlight lamp 100a. A plurality of devices are mounted between the support bars 30.
A light emitting module that emits light having a correlated color temperature (Correlated Color Temperature) of 9,000 ° K to 15,000 ° K is applied to the first fishlight 100a.
The second fish lamp 100b is mounted with a light emitting module that emits light having a correlated color temperature of 5,000 ° K to 8,000 ° K.
Each of the light emitting diodes 135 of the light emitting module 130 applied to the first and second fish lamps 100a and 100b preferably has the same structure except for the correlated color temperature or color of light emission. For convenience of explanation, it will be collectively referred to as a fish collection lamp, and its detailed structure will be described with reference to FIGS.
The fish collecting lights 100a and 100b include a main body 110, a light emitting module 130, and a cap 150.
The main body 110 has a rectangular cylindrical structure and is functionally divided into a structure having a body 111, a heat dissipation piece 116, and a rib 118.
The body 111 of the main body 110 has a rectangular opening having an open top, and has a tapered housing groove 112 whose width becomes narrower as it goes downward.
The radiation angle of the light emitted from the main body 110 is set in the range of 60 to 70 °.
The body 111 of the main body 110 is provided with a mounting groove 117 for mounting a cap 150 described later.
The mounting groove 117 is formed to recede downward in the main body 110 so as to be mounted lower than the upper surface of the main body 110 in a state where the cap 150 is mounted.
It is preferable that the inner wall 113 that is the portion of the body 111 that forms the housing groove 112 and that faces each other along the longitudinal direction of the body 111 has an angle (a) of 60 to 70 °.
On the other hand, as shown in FIG. 4 and FIG. 5, a method may be applied in which a tapered reflector 250 whose width becomes narrower as the upper part is opened and goes downward is combined in the body 111. The inner walls 213 facing each other of the reflecting umbrella 250 forming the second housing groove are preferably set so that the angle (b) between them is in the range of 60 to 70 °. A light transmitting hole is formed on the bottom surface of the reflector 250 so that the light emitting diode 135 is exposed.
The reflector 250 is preferably made of an aluminum plate whose inner surface is mirror-finished, or one that is silver or nickel plated so that the inner surface has a high reflectance.
On the other hand, the structure of the support bar for connecting the body 111 to the support wires 21 and 22 will be described with reference to FIGS.
First, the “L” -shaped first bracket 120 is fixed to the bottom surface of the body 111 using a fixing member such as a bolt at both ends. The holes formed on the side surface of the first bracket 120 correspond to the support bar 30. The through holes 32a and 32b formed as described above can be fixed using a fixing member such as a bolt 340. The support bar 30 has a structure having a portion twisted and bent in the longitudinal direction in order to match the coupling direction of the first bracket 120 and the support lines 21 and 22 for fixing the fishlights 100a and 100b.
In addition, the support bar 30 is formed with two through holes 32a and 32b for connecting the fish collection lamps 100a and 100b in the middle of the support bar 30 and bent at the upper end so as to surround the second support line 22. An open clip 33 is formed. In the clip portion 33, coupling holes are formed in portions facing each other for inserting bolts. In addition, the lower end of the support bar 30 is coupled to a second bracket 122 having a semicircular accommodation groove formed so as to surround and support a part of the first support line 21 by a fixing member such as a bolt 340. Thus, the coupling hole 36 is formed.
On the other hand, a structure different from the above-described figure may be applied to the support structure that supports the body 111.
The first fish lamp 100a and the second fish lamp 100b mounted by such a support device are mounted so that the emission directions of the light emitted from the ship 50 are different from each other.
As shown in FIG. 9, the first fish collection lamp 100a is used to guide and collect fish to be collected in a deep layer under a region close to several meters to several tens of meters from the ship, for example, a depth of 100 to 200 m. In addition, the optical axis corresponding to the center of the radiation angle (P1) of the light emitted from the first fish lamp 100a is directed to the water surface, and the angle between the reference line (S1) aligned on the water surface (S0) and the optical axis. (P1a) is set in the range of 35 to 45 °.
Further, the second fish collection lamp 100b is shown in FIG. 9 in order to guide the fish to be collected, which is far from the ship, for example, at a depth of several tens of meters from the surface water surface of several tens of meters to several hundreds of meters. As shown, the optical axis corresponding to the center of the emission angle (P2) of the light emitted from the second fish lamp 100b is directed to the water surface and between the reference line (S2) aligned with the water surface (S0) and the optical axis. The angle (P2a) is set in the range of 10 to 20 °.
The reason why the light emitted from the second fish lamp 100b is emitted so as to be emitted upward by about 20 to 30 ° with respect to the direction aligned with the water surface (see “d2” in FIG. 9) Considering the fact that the ship is tilted to the left and right, when the ship 50 is tilted, a relatively large amount of light is irradiated only in the vicinity of the ship, so that the fish collection efficiency of the fish to be collected at a long distance is reduced. It is because it prevents. Therefore, even when the ship 50 is tilted, it is possible to guide the fish collection of the fish to be collected located at a long distance due to the presence of light toward the reference line (S2) arranged on the water surface (S0).
In such an arrangement structure of the fish collection lamps 100a and 100b, the light having a correlated color temperature of 9,000 ° K to 15,000 ° K emitted from the first fish collection lamp 100a is a blue wavelength having a low light absorption rate in seawater. Since there is a relatively large amount of components, the light having a correlated color temperature of 5,000 ° K to 8,000 ° K emitted from the second fish lamp 100b can be reached from the surface of the water near the ship. Since there are relatively many long-wavelength components with low light absorptance in the sea mist and air, improving the efficiency of transmission to long distances, the collection of target fish to be collected in the deep layer near the ship and the surface layer of long distance Is efficient.
On the other hand, although not shown in the figure, the first and second fish lamps 100a and 100b may be arranged horizontally in a row, and the optical axes may be arranged differently as described above. May be arranged in a row in the center, and alternated by changing the direction of the fish collecting lights in both directions.
Referring to FIG. 2 again, the heat radiating piece 116 is formed to protrude from the body so as to extend from one side surface to the bottom surface and the other side surface perpendicular to the longitudinal direction of the body 111. A plurality of such heat radiating pieces 116 are formed apart from each other along the longitudinal direction of the body 111.
The rib 118 is extended outward in the horizontal direction along the periphery of the upper surface of the body 111.
In the rib 118, vent holes 119 penetrating vertically are formed apart from each other along the longitudinal direction in order to promote convection at a position corresponding to a region between the heat radiating piece 116 and the heat radiating piece 116.
The main body 110 uses a metal material painted with paint in order to prevent corrosion at sea, and it is preferable to apply aluminum with high heat dissipation efficiency as the metal material.
The light emitting module 130 is mounted on the bottom surface of the housing groove 112 of the main body 110, and a plurality of light emitting diodes 135 are mounted on the circuit board 131 so as to emit light toward the opening of the housing groove 112.
For the circuit board 131, MCPCB (Metal Cored Printed Circuit Board) with good heat dissipation is applied.
As described above, a light emitting diode 135 that emits white light having a correlated color temperature of 5,000 ° K to 8,000 ° K or 9,000 ° K to 15,000 ° K is used.
In this embodiment, a phosphor emitting white light, such as a YAG phosphor or a silicate phosphor, is applied to a blue light emitting diode chip, and the light emission is manufactured to have a correlated color temperature of 6500 ° K. The result of analyzing the spectrum of the emitted light with respect to the diode 135 is shown in FIG. As shown in FIG. 10, 60% or more of light is distributed in the wavelength range of 440 nm to 460 nm and 510 to 560 nm, which are blue to green wavelength ranges that are efficient for collecting squid fish.
On the other hand, a phosphor such as a YAG phosphor or a silicate phosphor was applied so as to emit white light to a blue light-emitting diode chip, and was manufactured to have a correlated color temperature of 10,000 ° K. FIG. 11 shows the result of analyzing the spectrum of the emitted light with respect to the light emitting diode 135. As an example of a method for generating the difference in correlated color temperature, the blending weight ratio between the phosphor and the transparent silicon used as the sealing agent may be adjusted.
As shown in FIG. 11, as the correlated color temperature increases, the light quantity specific gravity in the 440 nm to 460 nm band increases from the correlated color temperature of 6,500 ° K in FIG. 10.
The cap 150 is coupled to the main body 110 so as to close the opening of the receiving groove 112 of the main body 110.
Preferably, the cap 150 is made of a transparent material.
Reference numeral “154” is a sealing pad inserted between the cap 150 and the mounting groove 117 of the main body 110.
On the other hand, when the cap 150 is in the form of a lens having a curvature, the structure of the housing groove of the body 111 and the curvature of the cap 150 are appropriately set so that the radiation angle of light emitted from the main body 110 is 60 to 70 °. Apply to.
In the fish collection lamps 100a and 100b having such a structure, heat generated from the light emitting diode 135 is dissipated through the circuit board 131 and the main body 110 so that high output can be achieved, and the wavelength band of emitted light is efficiently used for collecting squid fish. By making the bands of 440 nm to 460 nm and 510 to 560 nm and limiting the light emission angle to 60 to 70 °, light can be used efficiently.
On the other hand, another structure of the fish collection lamp will be described with reference to FIG.
Referring to FIG. 12, the main body of the fish collection lamp includes a main board 410 for heat dissipation, a circuit board 430, and a reflecting mirror 470.
The heat dissipation main substrate 410 has a structure having a plate-like base plate 412 made of a metal material, an insulating layer 414 formed on the base plate 412, and a conductive pattern 416 made of a conductive material on the insulating layer 414.
The light emitting diode 135 is connected to the circuit board 430 through the conductive pattern 116.
The circuit board 430 is attached to the peripheral portion of the heat dissipation main board 410 and electrically connects the conductive pattern 416 and the wire connection terminal pads 434.
The reflecting mirror 470 is bonded to the upper part of the circuit board 430.
The reflecting mirror 470 focuses the light emitted from the light emitting diode 135 toward the side surface forward.
That is, the reflecting mirror 470 has a structure having a vertically penetrating opening at the center with a wide upper portion and a narrow lower portion so that the light emitting diode 135 is exposed.
The transparent cap 490 is for closing the opening of the reflecting mirror 470 so as to transmit light and is coupled to a mounting groove formed at the upper end of the reflecting mirror 470.
The transparent cap 490 may apply a Fresnel lens structure or other form of lens structure for inducing diffusion or light collection. Further, unlike the above-described example, the transparent cap 490 may be formed by filling the internal space of the reflecting mirror 470 with a transparent material such as silicon or epoxy.
Reference numeral “530” is an auxiliary plate joined to the lower part of the base plate 412.
The auxiliary plate 530 is applied in order to improve the heat dissipation capability, and a metal material having a high heat dissipation capability, such as an aluminum or copper material, is applied.
The covered core wire of the electric wire 520 is inserted into the terminal pad 434, and is coupled to the terminal pad 434 by soldering.
The cup cell mold part 540 is formed to ensure waterproofness and corrosion resistance against salt water. From the peripheral area of the transparent cap 490, the circuit board 430 and the auxiliary plate are exposed so that the bottom part of the auxiliary plate 530 is exposed. The molding process is performed by sealing up to the side surface of 530. The cup cell mold part 540 is molded by applying a material having waterproof properties and resistance to corrosion, such as an epoxy, a urethane material, and other plastic materials.
FIG. 12 shows a structure in which a heat radiation pin structure 550 having a plurality of heat radiation pieces 552 formed separately from each other at the lower portion of the support plate 551 is coupled to the lower portion of the auxiliary plate 530 in order to improve the heat radiation capability. FIG. 13 shows a structure in which a cooling water flow pipe 570 through which cooling water flows is coupled to the lower part of the auxiliary plate 530.
The cooling water circulation pipe 570 may be formed in the main body 110 of FIG.
When the cooling water flow pipe 570 is applied, as shown in FIG. 14, the cooling water flow pipes 570 are connected in series by a connection pipe 610, and are connected to the outlet side of the cooling water 610a. The compressor 620 that compresses the cooling water that flows out through the compressor and the condensing unit 630 that condenses the cooling water compressed by the compressor 620 are installed, and the cooling water is supplied through the connection pipe 610b on the inlet side. The system can be applied.
Reference numeral “632” is a condensing fan, and reference numeral “640” is a cooling water auxiliary tank.
The light emitting module 130 is more efficient for collecting fish in a driving method in which blinking is repeated than in a continuous driving method, and FIG. 15 shows an example of a control circuit for such blinking driving.
Referring to FIG. 15, a drive signal is input from a control unit (not shown) via a control signal input terminal 161, and the drive unit 163 that controls the FET 167 of the switching element by this drive signal turns on and off the light emitting diode 135. To drive. Reference numeral “165” is a buffer.
When the driving mode for driving such a light emitting module is turned on, the control unit drives the light emitting diodes to repeatedly blink on and off, and the lighting maintenance time and the lighting maintenance time are 0.1 to 0, respectively. .3 seconds are preferred.
On the other hand, in order to investigate the reaction characteristics for collecting squid, we tested the squid which were caught. Since fish squid caught in the aquarium become less reactive to light after 2 to 3 days, the fish behavioral experiment was conducted by putting the squid caught in the evening the day before the experiment into the aquarium in the morning of the day. After that, it went on the night of the day after the sun set. The water temperature of the water tank was set in the range of 10 to 23 ° C. according to the experiment day.
<Experimental water tank and equipment>
In order to easily observe the behavior of the Japanese squid, and to quantitatively indicate the distance traveled, the experimental tank has a length of 20 m, a width and a height of 0.8 m, and the height from the bottom to the water surface is 0. 0. It was 7 m. In addition, the 20-m long water tank was divided into 16 sections of 1.25 m each, and the position of the squid that were gathered for a certain period of time was invited by the light.
In the experiment, an approximately 50 W LED lamp in which 7 × 7 1 W LED elements were arranged was used, and five kinds of lamps representing white, red, yellow, green, and blue were applied to the lamps, respectively. In addition, 30 ° reflectors were provided on the front surface of the lamp, and the angle of the LED lamp was adjusted so that the yin yang of light was located at the boundary between the bottom of the first section and the bottom of the second section. In this way, the characteristics of the cuttlefish with respect to the shadow region can also be confirmed.
First, in the first experiment, five kinds of lamps were provided only on one side of the aquarium located in the dark, and 30 squids were confined by a net in a section with a length of 1 m in the middle of the aquarium, and the light was kept for about 30 seconds. After illuminating, the net was removed and released freely. After 5 minutes, the number of squid was recorded for each section. In the second experiment, two kinds of LED lamps having different wavelengths are aligned so as to face each other at both ends of the aquarium, and in the same way as in the first experiment, 30 squids have a width of 1 m in the middle of the aquarium. After being confined with a net and illuminated with light for about 30 seconds, the net was removed, and after 5 minutes, the number of squid was recorded for each section. In the third experiment, the LED lamps having the same wavelength with respect to the white light and the blue light are aligned so as to face each other at both ends of the water tank, and one of the lamps blinks at intervals of 0.1 to 0.3 seconds. The number of individuals in each section of the aquarium was recorded in the same manner as in the second experiment with the lamp turned on. The fourth experiment is the same as the second experiment, and lamps with wavelengths of 450 nm and 490 nm, and 450 nm and 460 nm are provided in order to obtain more accurate information on the wavelength of blue light that has the best attracting effect in the experiment described above. And compared.
The first experiment was performed five times, 25 times, and the second, third, and fourth experiments were performed 10 times, 100 times, 20 times, and 20 times. The power used was 28 W according to the principle of supplying the same energy.
In addition, in order to accurately measure the wavelength characteristics of the LED lamp used in the experiment, the wavelength of each LED lamp is analyzed using a spectral illuminometer (Spectro meter USB4000, THOR Co.) that enables spectral analysis by wavelength. did. The measurement position was 5 m away from the lamp.
White light is mainly a mixture of blue and green light wavelengths, and may have a little mixed yellow wavelength. The wavelength value of each lamp is about 634 nm of red light, 596 nm of yellow light, 523 nm of green light, and 454 nm of blue light, and the output value of light decreases in the order of red light, yellow light, green light, and blue light. It was the same.
<The color of LED lamps preferred by squids>
As a result of investigating the color of LED lamps preferred by squid, the most preferred color lamp was a blue light, followed by a white light and a green light, followed by a red light, and finally a yellow light. In particular, it has been clarified that squid have more negative phototactic behavior than positive one for red and yellow wavelengths. In addition, when the net was removed, the squid located at the center of the aquarium moved to the side where there was much light due to curiosity with respect to the light, and then moved to the shaded portions at both ends of the aquarium. After 5 minutes, the lightest squid in the brightest section located in the next section of the shaded area became relatively small. Until 5 minutes passed, about 2-3 squids reciprocated in the aquarium and the rest did not move. In other words, the squid will move positively for blue, green and white lights, negative for red and yellow lights, and move to the end of the aquarium. It was most often located in a dark place.
<Types of LED lamps preferred by squids>
As a result of comparison of LED lamps preferred by squid, both blue and white lights were preferred to flashing lights rather than regular lights. Quantitatively determining the number of squid moved, the blue flashing light (34.3%) was 10.6% higher than the constant light (23.7%) and the white flashing light (38%) was always on (26 %) Was 12.6% higher. Therefore, it is judged that the squid is very curious about the flashing lights.
<Types of blue LED lamps preferred by squids>
As a result of comparing the types of blue LED lamps preferred by squid, 450 nm lamps were preferred in comparative experiments between 450 nm wavelength lamps and 490 nm wavelength lamps. Quantitatively determining the number of squid moved, the 450 nm lamp (44.3%) was 12.3% higher than the 490 nm lamp (32%). In a comparative experiment between a lamp with a wavelength of 450 nm and a lamp with a wavelength of 460 nm, the difference between the 450 nm lamp (37.3%) and the 460 nm lamp (35.8%) is only 1.5%. It can be said that the lamps have almost the same attracting performance. Therefore, even in the blue LED lamp, it is judged that the lamp having a short wavelength band of 450 to 460 nm has high attracting performance for the squid.
On the other hand, according to such experimental results, from the viewpoint of simple fish collection efficiency, it is preferable to use blue light for fish collection, but only blue light is irradiated for workers who are fishing at the work site. Since it is difficult to distinguish colors for the work target object and the surrounding environment and it is easy to get tired, it is difficult to work for a long time.
Therefore, in order to alleviate the worker's visual fatigue and improve fish collection efficiency, as described above, white light generated by applying a YAG or silicate phosphor on a blue light emitting diode chip. By using, the visual fatigue level of the operator can be reduced, and the fish collection efficiency can be improved by the blue light having a main wavelength of 440 to 460 nm and the green light having a wavelength of 510 nm to 560 nm.
