Description

Specification

Fish collecting light device and method of using the same

Technical field

The present invention relates to a fishing light device used for fishing. Specifically, the background art belongs to the technical field of a fish-collecting light device for collecting marine animals such as squid, saury, horse mackerel, mackerel, etc.

[0002] Conventionally, in fishing operations, a fishing light has been used for the purpose of collecting as many target organisms as possible in the operating range of fishing gear and expanding the area of the sea around the own ship and linking it to fishing. The fishing process consists of the process of detecting the target organism (fish detection), the process of attracting (fish collection), and the process of catching (fishing). The light from the fishing light is an important factor that affects the efficiency of fishing. is there. The main target organisms for the fishing light fishing are squid, saury, horse mackerel, mackerel, etc., which have phototactic properties.

[0003] Light source technology used for fish-collecting lights has been developed based on the idea that increasing the light power is effective in increasing the catch. The light source for fish-collecting lights has been changing to acetylene lamps, incandescent lamps, and halogen lamps, and metal halide lamps are now the mainstream.

[0004] A metal halide lamp is a lamp in which argon for starting, mercury for adjusting the lamp voltage and the temperature of the arc tube and several kinds of metal halides are sealed in the arc tube, and uses light emission by metal atoms. It is. Metal halide lamps have more than four times the total luminous flux at the same power compared to the incandescent lamps conventionally used, and have improved luminous efficiency.

[0005] However, although metal halide lamps have improved luminous efficiency, they do not emit light that is not sufficient, resulting in large power consumption and heat dissipation, effects on ecosystems due to light pollution, and a short life span (1,200 to 3,600 hours). Problem. Further, there is a problem that a change in the lamp characteristics due to a change in the power supply voltage is large and a change in the emission wavelength is accompanied by a change in the emission color. In addition, there is also a problem that it takes about 10 to 15 minutes to start after turning on the power and about 10 to 15 minutes because it is necessary to cool the gas in the arc tube to relight. [0006] Therefore, recently, a fish-collecting lamp using a light-emitting diode instead of the lamp has been proposed. Patent Documents 1 and 2 disclose a fish-collecting lamp equipped with a blue light-emitting diode as a light source, and describe that fish can be effectively collected with low power consumption.

[0007] However, in these conventional fish-collecting lights, the light color is fixed. As a result, appropriate dimming such as changing the emission wavelength and emission (emission) intensity in accordance with the behavior of the operating sea area and target fish species cannot be performed, and it is difficult to improve fishing efficiency. was there.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a fishing light device according to the present invention and a method of using the same will be described based on each embodiment. First, an embodiment (1) of the present invention is shown in FIGS.

FIGS. 1 and 2 show a case where the fish-collecting light device according to the embodiment (1) is used for squid fishing. The fishing light device 100 includes a light source control unit 1 and a fishing light 2. The fishing light 2 is introduced into the sea from the fishing boat S by a wire 41 connected to the fishing light depth control device 4. The squid collected by the fishing light 2 catches the artificial baiting needle 32 of the fishing line 31 connected to the automatic squid fishing machine 3, so that the fishing line 31 is wound up by the automatic squid fishing machine 3 to capture power. can do.

[0028] The light emission state of the fish-collecting light 2 is controlled by the light source control unit 1 according to the operation information such as the light blue color of the target sea area, the illuminance condition, and the squid type 'position' reaction behavior. It is to be noted that, if necessary, by providing an umbrella portion 29 or the like that reflects light, the fish collecting light 2 can have directivity such that light emitted from the fish collecting light 2 is directed downward.

Hereinafter, a method of controlling the light emitting state of the fish-collecting light 2 according to various operation information will be specifically described.

First, a case where the light blue color of the fishing ground sea area is used as the operation information will be described. Fig. 1 shows the case where squid is present in the area al having different water colors and the area a2. By setting the emission wavelength of the fish-collecting light 2 so as to match the color of the seawater in the respective regions al and a2, the transmittance of light in the seawater can be increased and the fish-collecting effect can be improved. In addition, at night In operation, control the emission wavelength of the fish collector light 2 to match the color of the seawater observed during the day, and emit the underwater fish collector lamp 2.

[0030] It is known that the color of seawater is affected by plankton, suspended matter, dissolved and suspended substances, and the like. For example, phytoplankton and water bodies with little suspended matter have a blue color (wavelength 430-500 nm), and as the amount of phytoplankton increases or the area of the suspended matter becomes more marine, green (wavelength 510-550 nm) and yellow (wavelength 510-550 nm) The wavelength changes from 560 to 600 nm) and red (610 to 700 nm). As a method of observing the water color of the fishing grounds, there is a method of visually checking the seawater during daytime cruising. At this time, it is good to observe the color of the water in the sea area using Forel's Ule color meter. Forel 'Uhle water color meter is a light blue standard solution that shows the difference in water color in 21 levels. By comparing the water color seen directly above the water surface during the day with the Forel 'Uhle water color meter, it is possible to observe the water color of the sea area more accurately. It is also possible to automatically obtain the color of the sea water using a sea color shunt radiometer or the like.

Next, a case where an illuminance condition is used as operation information will be described. At high altitudes and strong sunlight, seawater is relatively bright due to the transmitted sunlight. In this case, squid can be attracted by changing the emission wavelength and intensity according to the set depth of the underwater fishing light. In addition, when operating under low illuminance conditions, such as at night, the amount of light in the seawater is small, so even if the luminous intensity of the fishing light source is set relatively low, it is possible to attract fish to be harvested. is there.

[0032] The illuminance condition changes according to the season, operating position, weather, time zone, and the like. As a method of observing the illuminance condition, there is a method of visually confirming the illuminance condition, but for more accurate observation, use an illuminometer or the like.

Next, a case where the operation information is the type of squid will be described. Figure 2 shows the types of squid to be caught in the squid and squid. In general, the squid's eye visual pigment has a high sensitivity to light in the wavelength range of 470 to 500 nm. I have. By setting the emission wavelength of the fish-collecting light 2 near the wavelength at which the spectral sensitivity of each type of squid is maximized, it is possible to efficiently attract various squids. FIG. 2 also shows a case where squids exist in different depth regions dl and d2. Depending on the depth of the sea, the density of plankton, suspended solids, dissolved 'suspended solids, etc. differs. When squid is present in the shallow depth dl, the density of plankton and suspended solids is high, so that the transmission maximum where the light transmittance is low generally moves to the longer wavelength side. Therefore, the emission wavelength of the fish-collecting light 2 is adjusted from blue corresponding to the clear water to slightly green, thereby increasing the emission intensity. Conversely, when squid is present in the depth region d2 deeper than the surface turbidity layer, the emission wavelength may be adjusted to the blue side corresponding to the clear water and set to a relatively small emission intensity. Methods for observing the squid's inhabiting depth and response behavior to light include monitoring the depth and behavior using a fish finder or sonar.

Next, a case will be described in which the distance between the fish-collecting light 2 and the squid and the reaction behavior characteristics of the squid are used as the operation information. Squid has an eye adapted to low-light environments and cannot respond to sudden changes in the light environment from a place to a light place. It is not expected to stay long in a bright environment. From such a viewpoint, in the embodiment (1), the squid is efficiently collected up to the vicinity of the fish-collecting light 2 by changing the emission intensity of the fish-collecting light 2 according to the distance between the fish-collecting light 2 and the squid. . In addition, as a method of measuring the distance between the fish-collecting light 2 and the squid, there is a method of obtaining the distance from the set depth of the underwater fish-collecting light and the position of the squid obtained from the fish finder Sona.

[0036] For example, at the start of the operation, the luminous intensity of the fish-collecting light 2 is set to be large in order to attract a wider range of squid. The squid is attracted, and the distance between the squid 2 and the squid is reduced, and the emission intensity of the squid 2 is reduced. Will be invited. In addition to the method of reducing the light emission intensity, a method of changing the light emission wavelength to a light emission wavelength with low transmittance in the sea and monitoring the effect with a fish finder and a sonar can be appropriately adopted.

[0037] Further, in order to increase the catching efficiency, it is necessary to increase the number of times the fishing tackle line is lowered and wound per unit time. Therefore, when the activity depth of squid is deep, it is necessary to recruit squid to a shallow area as shown in Figure 2. In this embodiment (1), at the start of the operation, the fish catching light 2 is lowered to a deep area, the luminous intensity is set large, and a wider range of squid is collected. Then, as the distance between the fish light 2 and the squid becomes shorter, By raising the fishing light 2 while reducing the intensity, it is possible to guide the squid to a shallower area. The fishing light 2 can be pulled up by winding the wire 41 by the fishing light depth adjusting device 4.

[0038] Based on the operation information such as the color of the seawater, the illuminance condition, the type of squid, the depth of the squid, the distance between the squid and the squid, the reaction behavior characteristics of the squid, etc. Although the control method has been described, in addition to the operation information, it is necessary to control the emission wavelength and the emission intensity based on operation information such as a change in seawater temperature, a flow direction and velocity of a tidal current, and behavior of a fishing tackle line. Is also possible.

In the above description, the method of controlling the light emission state of the fish-collecting light 2 based on one piece of operation information has been described. However, a plurality of actually obtained pieces of operation information are combined to obtain the emission wavelength and emission intensity. May be controlled.

Further, in the above description, the present invention is applicable to various phototactic animals such as saury, mackerel and mackerel, in addition to the power squid described in the case of attracting squid.

Next, the device configuration of the fish collecting light device 100 will be described. As shown in FIG. 3, a fishing light device 100 according to this embodiment (1) includes a fishing light 2 having a light source 20 and a light source control unit 1 for changing a light emitting state of the light source 20 according to operation information. Are connected to each other. The light source control unit 1 includes an operation unit 10 for setting a light emission state of the light source 20 and a circuit unit 13 for outputting a signal input to the operation unit 10 to the light source 20.

[0042] The operation unit 10 is provided with a volume unit 12 for changing the light emission state of the light source 20, and a scale unit 11 corresponding to the set position of the volume unit 12.

Specifically, as shown in FIG. 4, the operation unit 10 is composed of, for example, a box-shaped operation panel, and changes an emission wavelength volume 12 a for changing the emission wavelength of the light source 10 and an emission intensity. A light emission intensity volume section 12b, and each volume section is configured so that the light emission wavelength and intensity can be continuously changed by sliding a knob 120. Further, an emission wavelength scale section 11a and an emission intensity scale section lib are provided along the emission wavelength volume section 12a and the emission intensity volume section 12b, respectively. The emission wavelength scale section 11a is made of, for example, a band-like display member that simulates the spectrum in the visible light range, and the emission wavelength of the light source 20 corresponding to the position of the knob 120 is intuitively recognized. You can do it. Further, the light emission intensity scale part l ib is formed, for example, in a triangular shape, so that the user can intuitively recognize that moving the knob 120 changes the light emission intensity of the light source 20. In addition, a numerical scale is also provided as an index to reproduce the setting of the emission spectrum 'scale and emission intensity.

The emission wavelength volume section 12a and the emission intensity volume section 12b include, for example, a variable resistor, and a voltage value corresponding to the set value is input to the AD terminal of the CPU 131. Then, after the AD conversion by the CPU 131, the current value for each of the RGB light emitting diodes 21 is calculated. A current command value based on the calculation result is output to the constant current circuit 132, and a current is supplied to each light emitting diode to control the light emission amount of each light emitting diode.

In this embodiment (1), the operation unit 10 is provided with a white light switch 14 that can convert the light emission color of the light source 20 to white with one touch by turning on each of the light emitting diodes 21 of RGB. I have. As described above, the present invention is characterized in that the light emitting state is arbitrarily controlled in accordance with the operation information by operating the volume unit 12 and the like. Working in the light can cause complementary color phenomena and retinal inflammation that can interfere with the eyes. Therefore, such a situation can be prevented by equipping the white light switch 14 capable of one-touch switching to white light. In other words, monochromatic light with a controlled emission wavelength is used until the distant target organism is brought close to the fishing boat S, and then, by switching from monochromatic light to white light with a switch, the target fish that has been collected nearby can be collected. It is possible to create a light environment with less burden on the worker while avoiding escape.

Next, the fish collecting light 2 will be described.

In addition, the fishing light 2 is provided with a mounting device 24, which is put into the sea by a wire 41 and used. Then, the fishing light 2 and the light source control unit 1 are connected by an input / output line 23, and a signal for controlling each light emitting diode 21 is transmitted. In FIG. 5, for convenience, the umbrella section 29 shown in FIG. 1 is omitted.

As shown in FIG. 5B, each light emitting diode 21 is mounted on the light emitting diode mounting substrate 2. 6 is arranged on. Then, a part of the light emitting diode 21 and the surface of the light emitting diode mounting board 26 are coated with waterproof silicon 27 and subjected to waterproof treatment.

[0047] The fish collecting light 2 is provided with a through hole 25 for cooling the light emitting diode 21 through seawater. Specifically, as shown in FIG. 5 (b), a through hole 25 is formed along the length direction of the cylindrical housing 22, so that when the fishing light 2 is submerged underwater, seawater penetrates. Utilizing the natural flow into the hole 25, the light emitting diode 21 is cooled to increase the luminous efficiency.

In this embodiment (1), the light emitting diode 21 includes a red light emitting diode 211, a blue light emitting diode 212, and a green light emitting diode 213 as shown in the enlarged view of FIG. ing. As shown in FIGS. 6 and 7, by controlling the light emission amounts of the three-color light-emitting diodes, respectively, the apparent emission wavelength emitted from the light-emitting diode 21 as a composite of them is, for example, Hl in FIG. 6, FIG. Then, the light emission intensity of the light emitting diode 21 can be changed so as to be H2. As a result, toning and dimming of the entire light source 20 can be performed freely.

[0049] The circuit configuration of the light source control unit 1 and the fish collecting lamp 2 can be appropriately designed without being limited to the example of FIG. For example, as shown in FIG. 8, the connection of the light emitting diodes 21 can be partially parallel.

In this embodiment (1), the case where the red light emitting diode 211, the blue light emitting diode 212, and the green light emitting diode 213 are incorporated in one light emitting diode 21 has been described. It is not something to be done. For example, as shown in FIG. 9, a monochromatic red light emitting diode 211, a blue light emitting diode 212, and a green light emitting diode 213 are used, respectively, and they are arranged alternately to form a light source 20 as a whole. Toning and dimming may be performed.

[0050] In the above embodiment (1), the column-shaped underwater fish-collecting light is described. However, the present invention is not limited to this, and may be any shape such as a sphere or a polygonal column.

The fish-collecting light 2B has a housing 22b formed in a flat shape, and a plurality of light emitting diodes 21 are spread on one surface of the sea surface side. Also The other side of the housing 22b is provided with a mounting device 24b for fixing on the ship, and a cooling fan 28 is provided on a side surface of the housing 22b to emit light from inside the housing 22b.
