Description

FISHING LIGHT DEVICE AND USAGE OF THE SAME}

The present invention relates to a fishing lamp device used for fishing. Specifically, it belongs to the technical field of the fishing device for collecting marine animals, such as a cuttlefish, saury, horse mackerel, and mackerel, and to connect with a catch.

Conventionally, in the operation of fishing, fishing and the like have been used for the purpose of collecting as many target organisms as possible in the operating range of fishing gear from the sea area wider than the surrounding area of the charity and attaching them to fishing. The fishing process consists of the process of detecting the target organism (exploration), the process of collecting (collecting), and the process of catching the fish (catching), and the back light of the fish is an important factor that determines the efficiency of fishing. The main target organisms of the fishing mackerel include daylight squid, saury, horse mackerel and mackerel.

The development of the light source technology which can be used for picking-up etc. based on the idea that it is effective to increase a light power in order to increase a catch amount has been advanced. Light sources such as pick-ups have been changed into acetylene lamps, incandescent lamps and halogen lamps, and now metal halide lamps have become mainstream.

The metal halide lamp is a lamp in which argon for starting, mercury for controlling the lamp voltage, the light tube temperature, and several metal halides are enclosed in the light emitting tube, and light is emitted from metal atoms. The metal halide lamp has a total luminous flux of four times or more at the same electric power as compared with the incandescent lamp which has been used conventionally, and the luminous efficiency is improved.

However, metal halide lamps have improved luminous efficiency, but they are not sufficient, but they have problems such as high power consumption and heat dissipation due to light emission, impact on the ecosystem by the mine, and short lifespan (1,200 to 3,600 hours). . In addition, there is a large change in the lamp characteristics due to variations in the power supply voltage, and there is a problem involving a change in the emission wavelength, that is, a change in the emission color. In addition, since the gas in the arc tube needs to be cooled in order to restart the engine for about 10 minutes after the power is applied, there is a problem that a time of about 10 to 15 minutes is required.

In recent years, a pick-up lamp using a light emitting diode instead of the lamp has been proposed. Japanese Laid-Open Patent Publication Nos. 2003-134967 and 2000-125698 disclose a fishing lamp equipped with a blue light emitting diode as a light source, and describes that fish can be effectively collected at a low power consumption.

However, in these conventional picking lights, the orange color was fixed in all of them. For this reason, since it is impossible to perform appropriate dimming such as changing the emission wavelength or the emission (radiation) intensity in accordance with the operation area or the behavior of the target fish species, there is a problem that it is difficult to lead to the improvement of the fishing efficiency.

In addition, in the present invention, in view of the above-mentioned conventional situation, light emission is performed on the basis of various operation information such as the color of water in the fishing area, the roughness condition, the type of organism to be caught, the position, depth and behavior characteristics of the organism to be caught. It is an object of the present invention to provide a fishing lamp device and a method of using the same, which can be appropriately controlled and can be connected to improve fishing efficiency.

It is a pick-up lamp device provided with the light source control part which changes a light emission state by performing coloring as the whole light source.

EMBODIMENT OF THE INVENTION Hereinafter, the pick-up lamp apparatus which concerns on this invention, and its usage method are demonstrated based on each Example. First, the first embodiment of the present invention is shown in Figs.

1 and 2 show a case where the fishing lamp device according to the first embodiment is used for squid fishing. The catching lamp device 100 is comprised from the light source control part 1 and the catching lamp 2. The catcher 2 is injected into the sea from the fishing boat S by the wire 41 connected to the catcher depth control device 4. Since the squid collected by the fishing lamp 2 catches the artificial lure needle 32 of the fishing line 31 connected to the automatic squid fishing 3, the fishing line 31 is wound up by the automatic squid fishing 3 By raising, a squid can be caught.

The light emission state of the catcher 2 is controlled by the light source control unit 1 in accordance with operation information such as search of the target area, illuminance conditions, species, position, reaction behavior of the cuttlefish, and the like. In addition, by providing the umbrella part 29 etc. which light reflects to the pick-up lamp 2 as needed, it can also make it directional by changing the light which arises from the pick-up lamp 2 to face downward.

Hereinafter, the method of controlling the light emission state of the said collecting lamp 2 according to various operation information is demonstrated concretely.

First, a description will be given of the case where the search of the fishery area is used as the operation information. FIG. 1 shows the case where a cuttlefish exists in the area | region a1 from which the color of water differs, and the area | region a2. By setting the light emission wavelength of the catching lamp 2 to match the color of the seawater in each of the regions a1 and a2, it is possible to increase the transmittance of light in the seawater and to improve the picking effect. In addition, when operating at night, it controls so that the light emission wavelength of the fishing lamp 2 may match the color of the seawater observed during the day, and the underwater fishing lamp 2 is made to emit light.

In addition, the color of seawater is known to be affected by plankton, suspended matter, dissolved and suspended substances, and the like. For example, in phytoplankton or water lumps with little suspension, it becomes blue (wavelength 430-500 nm), and green (wavelength 510-550 nm), yellow as phytoplankton increases, or it becomes many sea areas of suspension. (Wavelengths of 560 to 600 nm) and red (wavelengths of 610 to 700 nm). As a method of observing the search of the fishery sea area, the method of visually confirming the sea water in the main port during the day is mentioned. At this time, it is also possible to observe the color of water in the sea area using a forel and a Ulle colorimeter. The Porel-Ulle colorimeter is a color standard solution that displays the difference in water color in 21 colors. By comparing the water color seen from directly above the surface of the water during the day and the Porel-Ulle colorimeter, the water color in the sea area can be observed more accurately. In addition, it is also possible to automatically obtain the color of the sea water using a color scanning radiation system.

Next, a case where the illuminance condition is used as the operation information will be described. When the solar altitude is high and the daylight intensity is strong, the seawater becomes relatively bright due to the transmitted sunlight. In this case, the cuttlefish can be collected by changing the light emission wavelength and the intensity in accordance with the set depth of the underwater fish. In addition, when operating under conditions of low illuminance such as night, the amount of light in the seawater is small. Therefore, even if the light emission intensity of the light source is set relatively small, it is possible to collect the catch target organism.

In addition, illuminance conditions change according to season, operation position, weather, time zone, etc. As a method of observing an illumination condition, the method of visually confirming is mentioned, but an illumination meter etc. can be used in order to observe more accurately.

Subsequently, the case where the operation information is a kind of squid will be described. FIG. 2 shows a case where the kinds of squids to be caught are red squids and squids. In general, squid eye specimens have high sensitivity to light around wavelengths of 470 to 500 nm, but red squids and squids, which are the targets of squid fishing, are known to exhibit maximum sensitivity at different wavelengths. By setting the light emission wavelength of the fishing lamp 2 to near the wavelength where the spectral sensitivity of each kind of cuttlefish becomes the maximum, it is possible to efficiently collect various cuttlefish.

2 also shows the case where squid exists in different depth areas d1 and d2. Depending on the depth of the sea, the density of plankton, suspended solids, dissolved and suspended solids, etc. are different. When squid exists in the area | region d1 with a shallow depth, since the density of a plankton and a suspended substance is high, it is common for the light transmittance to be low and the transmission maximum moves to a long wavelength side. Therefore, the light emission wavelength of the catching lamp 2 is adjusted from blue corresponding to the clarification water to a somewhat green side, and the light emission intensity is increased. On the contrary, when squid is present in the depth area d2 deeper than the surface high turbidity layer, the emission wavelength may be adjusted to the blue side corresponding to the clarification water, and set to a relatively small emission intensity. The squid's depth of field and how to observe the light's reaction behavior include the use of fish and sound wave detectors to monitor depth and behavior.

Subsequently, a description will be given as to the operation information using the distance between the fishing lamp 2 and the cuttlefish and the reaction behavior characteristic of the water cuttlefish. Because squid has eyes adapted to low light environment and cannot cope with sudden change of light environment from dark place to bright place, it is thought that eye compliance does not stay long in bright environment that seems to be unable to cope immediately for a long time. . In view of this, in the first embodiment, the cuttlefish is efficiently collected to the vicinity of the catching lamp 2 by changing the light emission intensity of the catching lamp 2 in accordance with the distance between the catching lamp 2 and the cuttlefish. Moreover, as a measuring method of the distance between the fishing lamp 2 and the water squid, the method of obtaining from the set depth of underwater fishing etc. and the position of the squid obtained from the fish finder and the sound wave detector are mentioned.

For example, at the start of the operation, in order to collect a wider range of squid, the light emission intensity of the fishing lamp 2 is set large. When the cuttlefish is collected and the distance between the pickling lamp (2) and the water cuttlefish is near, the luminous intensity of the pickling lamp (2) is reduced together to prevent the squid from being collected in the collecting process, and the pickling lamp (2) Squid groups are to be collected to the vicinity of. In addition to the method of reducing the light emission intensity, a method of changing the light emission wavelength to a light emission wavelength having a low transmittance in the sea and monitoring the effect by a fish detector or a sound wave detector can be suitably used.

In addition, in order to increase the fishing efficiency, it is necessary to increase the number of dropping and winding-up of the fishing line per unit time. Therefore, when the activity depth of a cuttlefish is deep, as shown in FIG. 2, it is necessary to collect a cuttlefish to a shallow area. In the first embodiment, at the start of the operation, the pick lamp 2 is lowered to a deep depth region, the luminous intensity is set large, and a wider range of squid is collected. Then, as the distance between the fishing lamp 2 and the cuttlefish approaches, the squid can be guided to a shallow depth by raising the fishing lamp 2 while reducing the light emission intensity. In addition, pulling up the pick-up lamp 2 can be performed by winding the wire 41 by the pick-up depth controller 4.

As described above, the method of controlling the light emission state of the fish, such as the color of the seawater, the illumination condition, the type of the squid, the depth of the squid, the distance between the fish and the squid, and the reaction behavior of the squid, etc. As described above, in addition to the above operation information, it is also possible to control the emission wavelength and the emission intensity based on operation information such as changes in sea water temperature, algae direction and flow rate and fishing line behavior.

In addition, in the above, the method of controlling the light emission state of the picking lamp 2 based on one operation information has been described. However, the light emission wavelength and the light emission intensity can be controlled by integrating a plurality of operation information actually obtained. .

In addition, in the above, the case of collecting squid is mentioned, but it is applicable to aquatic animals with various daylight, such as saury, horse mackerel, and mackerel other than squid.

Next, a device configuration of the catching device 100 will be described. The catcher device 100 according to the first embodiment includes a catcher 2 having a light source 20 and a light source controller for changing the light emission state of the light source 20 according to operation information as shown in FIG. 3. It is roughly comprised by connecting (1). 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. have.

The operation part 10 is provided with the volume part 12 which changes the light emission state of the light source 20, and the scale part 11 corresponding to the setting position of the volume part 12. As shown in FIG. Specifically, as shown in FIG. 4, the operation unit 10 is composed of, for example, an operation panel formed in a box shape, and has a light emission wavelength volume 12a for changing the light emission wavelength of the light source 10. And a light emission intensity volume portion 12b for changing the light emission intensity, and each volume portion is configured to continuously change the light emission wavelength and intensity by sliding the knob 120. In addition, the light emission wavelength scale part 11a and the light emission intensity scale part 11b are provided so as to correspond to the light emission wavelength volume part 12a and the light emission intensity volume part 12b. The light emission wavelength scale portion 11a is made of, for example, a band-shaped display member that mimics the spectrum of visible light, and the light emission wavelength of the light source 20 corresponding to the position of the knob 120 can be intuitively recognized. It is supposed to be. In addition, the luminous intensity scale part 11b is configured in a triangular shape, for example, so that the luminous intensity of the light source 20 is changed intuitively by moving the knob 120. In addition, a numerical scale is also provided as an index for reproducing the setting of the emission spectrum scale and the emission intensity.

The light emission wavelength volume portion 12a and the light emission intensity volume portion 12b have, for example, a variable resistance, and a voltage value corresponding to the set value is input to the AD terminal of the CPU 131. After the AD conversion in the CPU 131, the current value for each light emitting diode 21 of RGB is calculated. The current command value based on the calculation result is outputted to the constant current circuit 132 so that a current flows to each light emitting diode, and each light emission amount is controlled.

In addition, in this first embodiment, the white light switch 14 which can convert the light emission color of the light source 20 into white with one touch is provided separately by lighting each LED 21 of RGB in the operation part 10, have. As described above, the present invention is characterized in that the light emission state is arbitrarily controlled in accordance with the operation information by operating the volume unit 12 or the like. However, for example, a worker works under a monochromatic light such as blue / green on a ship. Doing so can cause retardation or retinitis, which can cause eye irritation. Thereby, such a situation can be prevented by providing the white light switch 14 which can be one-touch-converted to white light. That is, until the distant catching creature is placed in the vicinity of the fishing vessel S, the monochromatic light which controlled the emission wavelength is used, and after that, by switching from monochromatic light to white light, the target fish picked up nearby do not run away, It is possible to create a light environment with less load on the operator.

Next, the pick-up lamp 2 is demonstrated. FIG. 5A is a perspective view of the catching lamp 2 according to the first embodiment, and FIG. 5B is an A-A cross-sectional view thereof. The pick-up lamp 2 can attach a plurality of light-emitting diodes 21 to the circumferential surface of the cylindrical body 22, so that light can be emitted in all directions. Moreover, the attachment lamp 24 is provided in the pick-up lamp 2, and can be thrown in the sea by the wire 41, and can be used. Then, the catching lamp 2 and the light source control unit 1 are connected to the input / output line 23, and a signal for controlling each light emitting diode 21 is sent. In addition, in FIG. 5, the umbrella part 29 shown in FIG. 1 is abbreviate | omitted for convenience.

As shown in FIG. 5B, each light emitting diode 21 is provided on the light emitting diode mounting substrate 26. As shown in FIG. The water-resistant silicon 27 is coated on a part of the light emitting diode 21 and the surface of the light emitting diode mounting substrate 26 to perform waterproofing.

The pick-up lamp 2 is also provided with a through hole 25 for cooling the light emitting diode 21 through seawater. Specifically, as shown in FIG. 5B, the through hole 25 is formed along the longitudinal direction of the cylindrical body 22, and the seawater penetrates the seawater 25 when the picking lamp 2 is sunk in the water. ), The light emitting diode 21 is cooled, and the light emitting efficiency is increased by using naturally flowing into the light.

In this first embodiment, the light emitting diode 21 has 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. 5B. As shown in Figs. 6 and 7, by controlling the light emission amounts of the three-color light emitting diodes, the apparent light emission wavelengths generated from the light emitting diodes 21 are synthesized, for example, H1 in Fig. 6. In FIG. 7, the light emission intensity of the light emitting diodes 21 may be changed to change to H2. As a result, coloration and dimming of the light source 20 as a whole can be performed freely.

The circuit configuration of the light source control unit 1 and the collecting lamp 2 is not limited to the example of FIG. 4, and can be appropriately designed. For example, as shown in Fig. 8, the connection of the light emitting diodes 21 can be partially parallel.

In addition, in the first embodiment, the case where the red light emitting diode 211, the blue light emitting diode 212, and the green light emitting diode 213 are built in one light emitting diode 21 is described. It doesn't happen. For example, as shown in FIG. 9, the monochromatic red light emitting diodes 211, the blue light emitting diodes 212, and the green light emitting diodes 213 are used, respectively, and they are alternately installed, and a light source is provided. (20) Coloring and dimming as a whole can be performed.

Although the above-mentioned 1st Example mentioned the cylindrical underwater pick-up etc., it is not limited to this, It can be set as arbitrary shapes, such as a spherical shape and a polygonal column shape.

Also, Fig. 10 shows a second embodiment of the present invention. This picking-up lamp 2B is installed on a ship and emits light toward the sea surface. The pick-up lamp 2B has a plate 22b formed in a flat plate shape, and a plurality of light emitting diodes 21 are laid on one surface of the sea surface side. The other side of the housing 22b is provided with an attachment mechanism 24b for fixing on the ship, and a cooling fan 28 is provided on the side of the housing 22b to emit light inside the housing 22b. The diode 21 can be cooled.

By using the fishing boat 2B for ships, various catch objects, such as saury, can be picked up efficiently.

The pincers used on the ship are not limited to the flat plate shape of the second embodiment, but may be any shape such as a curved or polygonal column.

In the second embodiment, the configuration of the light emitting diode 21, the method of controlling the light emission state by the light source control unit 1, and the like are the same as in the first embodiment.

According to the present invention, since a plurality of light emitting diodes having different emission colors are controlled according to the color of water in the sea area and the fishery information of the species and the reaction behavior of the fish, the coloration and dimming suitable for the situation can be varied. As a result, the fishing efficiency can be improved.

In addition, since any color (wavelength) in the visible light range can be emitted, it is not necessary to change the light source depending on the species to be caught or the sea area.
