Description
本発明は、配光を最適化することによって効率を改善し、集魚能力を損なうことなく消費エネルギーを削減することができる集魚灯装置、特にイカ釣り用に有用な集魚灯装置に関する。 The present invention relates to a fishlight device that can improve efficiency by optimizing light distribution and reduce energy consumption without impairing the ability to collect fish, and more particularly to a fishlight device useful for squid fishing.
イカ釣り漁業は、漁船の甲板上に集魚灯を複数吊り下げて点灯し、船下に集まったイカを自動イカ釣り機ないし手釣りによって釣り上げる漁法である。
従来、イカ釣り用集魚灯の光源として主にメタルハライドランプが使用されてきた。メタルハライドランプは、高輝度で、漁獲を促進させる作用がある半面、消費電力が大きく、これを点灯するためには大容量の発電設備が要求される。
また、集魚灯の点灯時には、発電用の機関によって膨大な量の燃料油が消費され、コスト増大の要因になっていた。
Squid fishing fishery is a fishing method in which a plurality of fishing lights are suspended and lighted on the deck of a fishing boat, and the squid gathered under the boat is fished by an automatic squid fishing machine or hand fishing.
Conventionally, a metal halide lamp has been mainly used as a light source for a fishing light for squid fishing. A metal halide lamp has high brightness and has an effect of promoting fishing, but consumes a large amount of power, and a large-capacity power generation facility is required to light it.
Further, when the fish lamp is turned on, a huge amount of fuel oil is consumed by the power generation engine, which causes an increase in cost.
メタルハライドランプは、光源中心から立体角約４πのほぼ全方向に光束が放射される。これらの光束のうち、集魚に有効に作用するものは海面に到達した光束のみであるが、多くの光束は、天空や甲板に向かって放射され、集魚に全く関与せず、無駄になっている。
このようなことから、集魚灯の配光を制御し、無駄に放射される光束を海面に振り向けて集魚に有効な光束を増やす方法が、集魚灯の効率向上の手段として考えられてきた。
The metal halide lamp emits a light beam in almost all directions with a solid angle of about 4π from the center of the light source. Of these luminous fluxes, only the luminous flux that has reached the sea surface is the one that effectively acts on the fish collection, but many of the luminous flux is radiated toward the sky and the deck and is not involved in the fish collection at all and is wasted. .
For this reason, a method of increasing the luminous flux effective for fish collection by controlling the light distribution of the fish collection lamp and directing the luminous flux emitted unnecessarily to the sea surface has been considered as a means for improving the efficiency of the fish collection lamp.
しかしながら、集魚灯用メタルハライドランプは陸上の光源と比較して大型であるがゆえに、文献１に示すような反射板を備えた配光制御機構は大型かつ複雑になりがちである。漁船では、設置スペースが限られるため、このような装置は実用化が困難である。
また、文献２に示すように、反射板等により配光制御機能を付加した集魚灯装置は、海面に光束が到達する効率が高い半面、指向性が強くなることから、照射範囲が狭くなり、広い範囲からイカを集める機能が失われる欠点を持っている。
However, since the metal halide lamp for fish collection lamp is larger than the land light source, the light distribution control mechanism including the reflector as shown in Document 1 tends to be large and complicated. Since fishing boats have limited installation space, it is difficult to put such devices into practical use.
In addition, as shown in Document 2, the fish collection lamp device to which the light distribution control function is added by a reflector or the like has a high efficiency in which the light beam reaches the sea surface, and the directivity becomes strong. It has the disadvantage of losing the ability to collect squid from a wide range.
省電力効果が期待される光源として発光ダイオード（ＬＥＤ：Ｌｉｇｈｔ Ｅｍｉｔｔｉｎｇ Ｄｉｏｄｅ）があり、特許文献３及び特許文献４に示す通り、これを集魚灯に適用することが提案されている。
しかし、発光ダイオードを光源として用いた集魚灯は、重量や投影面積が大きく、十分な漁獲能力を得るべく大量の集魚灯を甲板上に搭載した場合、重心の上昇や風圧抵抗の増加など、漁船の安全性に与える負の影響が大きかった。
There is a light emitting diode (LED) as a light source that is expected to have a power saving effect. As shown in Patent Document 3 and Patent Document 4, it has been proposed to apply this to a fish collecting lamp.
However, the fishing lights that use light-emitting diodes as light sources are heavy and have a large projected area, and when a large number of fishing lights are mounted on the deck to obtain sufficient fishing capacity, the fishing boats may increase the center of gravity or increase wind pressure resistance The negative impact on the safety of
本発明は、上記諸問題を解決するものであって、照射範囲の最適化によって、広い範囲からイカを集める機能を損なうことなく効率を向上させ、エネルギー消費量を低減するイカ釣り用集魚灯を提供することを課題とする。 The present invention solves the above-described problems. By optimizing the irradiation range, a fishing light for fishing for squid that improves efficiency without reducing the function of collecting squid from a wide range and reduces energy consumption is provided. The issue is to provide.
本発明の第１の課題解決手段は、発光部分が小さく、高輝度で点光源に近い無電極プラズマランプないしレーザー照明装置を光源として用いることである。これによって、装置全体の小型化が可能になるとともに、実質的な点光源であることによって、配光制御機構の構造を単純化することができる。 The first problem-solving means of the present invention is to use an electrodeless plasma lamp or laser illumination device having a small light emitting portion, high luminance and close to a point light source as a light source. As a result, the entire apparatus can be miniaturized and the structure of the light distribution control mechanism can be simplified by being a substantial point light source.
本発明の第２の課題解決手段は、前項の光源を下向きに点灯し、１つ以上の反射鏡またはレンズ、およびこれらの組み合わせによって、光軸を水平方向に向けることである。ただし、配光のピークは仰俯角方向では水平方向とするが、方位角方向では特定の方向に光束を絞り込まず、拡散するよう照射方向を制御する。
光源を下向きに点灯することによって、天空方向への照射が抑制され、配光制御機構によって、甲板方向へ向かう光束が偏向し、海面へ向かう配光が強化される。また、上記のような配光とすることによって、広い範囲からイカを集める機能を確保する。
The second problem-solving means of the present invention is to turn on the light source in the previous section downward and to direct the optical axis in the horizontal direction by one or more reflecting mirrors or lenses and combinations thereof. However, although the peak of the light distribution is the horizontal direction in the elevation angle direction, the irradiation direction is controlled so as to diffuse without narrowing the light beam in a specific direction in the azimuth direction.
By turning on the light source downward, irradiation in the sky direction is suppressed, and the light distribution control mechanism deflects the light flux toward the deck direction and enhances the light distribution toward the sea surface. Moreover, the light distribution as described above ensures the function of collecting squid from a wide range.
本発明の第３の課題解決手段は、上記を実現し、集魚灯として必須の要件である防水性能および耐久性能を満たすため、集魚灯本体を、光源と、光源を点灯するための駆動装置と、配光を制御するための機構と、光束を透過させるための透明ガラスを備えた筐体と、前記光源を冷却するためのヒートシンクを一体化させた構造とすることである。 The third problem-solving means of the present invention realizes the above, and satisfies the waterproof performance and durability performance, which are essential requirements for a fish-collecting lamp, a fish-collecting lamp main body, a light source, and a drive device for lighting the light source. The structure for integrating the mechanism for controlling the light distribution, the housing provided with the transparent glass for transmitting the light flux, and the heat sink for cooling the light source.
具体的には、次の発明を提供するものである。
１）漁船の船上に設置する集魚灯装置であって、天空および甲板方向の配光を抑制し、海面方向の配光を強化することを特徴とする集魚灯装置。
２）光源と、光源を点灯するための駆動装置と、配光を制御するための機構と、光束を透過させるための透明ガラスを備えた筐体と、前記光源および駆動装置を冷却するためのヒートシンクを備えることを特徴とする上記１）の集魚灯装置。
３）光源として、無電極プラズマランプまたはレーザー光源を用いることを特徴とする上記２）の集魚灯装置。
４）配光を制御するための機構として、少なくとも１枚以上の反射鏡または／およびレンズを用いることを特徴とする上記２）の集魚灯装置。
５）配光を制御するための機構が、集魚灯装置の中心から水平の方向に最大の配光ピーク形成することを特徴とする上記２）の集魚灯装置。
Specifically, the following invention is provided.
1) A fish lamp device installed on a fishing boat, which suppresses light distribution in the sky and deck directions and enhances light distribution in the sea surface direction.
2) a light source, a driving device for turning on the light source, a mechanism for controlling light distribution, a housing provided with transparent glass for transmitting a light beam, and for cooling the light source and the driving device 1. The fish lamp device according to 1) above, further comprising a heat sink.
3) The fish lamp device of 2) above, wherein an electrodeless plasma lamp or a laser light source is used as the light source.
4) The fish lamp device according to 2) above, wherein at least one reflector or / and a lens is used as a mechanism for controlling light distribution.
5) The fishlight device of 2) above, wherein the mechanism for controlling the light distribution forms a maximum light distribution peak in the horizontal direction from the center of the fishlight device.
本発明の集魚灯によって、海面に到達する光束の割合が従来型漁灯よりも増加する。当該集魚灯の配光は、狭い範囲に絞り込まない設計であるため、照射範囲が従来型漁灯並みに確保される。以上のことから、従来型漁灯よりも少ないエネルギー消費で同等の効果をもたらすことができる。また、光源形状が点光源に近いことから、配光制御機構および本体をコンパクトに設計することが可能で、漁船に搭載した際の安全性も確保される。 The ratio of the luminous flux reaching the sea surface is increased by the fish collecting lamp of the present invention as compared with the conventional fishing lamp. The light distribution of the fish collection lamp is designed so as not to be narrowed down to a narrow range, so that the irradiation range is assured as a conventional fishing light. From the above, the same effect can be brought about with less energy consumption than conventional fishing lights. Moreover, since the light source shape is close to a point light source, the light distribution control mechanism and the main body can be designed in a compact manner, and safety when mounted on a fishing boat is ensured.
以下、本発明の実施するための形態を図面に基づき説明する。ただし、図面は、本発明の技術的思想を例示するもので、本発明を図面上の記載事項に限定するものではない。
本発明の集魚灯の全体図を図１に、図１の平面Ａにおける断面図を図２に、また本発明による配光イメージを図３および図４にそれぞれ示す。無電極プラズマランプ又はレーザー照明装置による光源１は、筐体５の上部に発光部を下向きにして設置される。
光源から放射された光束は光源の下方に位置する配光制御機構２によって仰俯角方向には水平向きに偏向される。また、配光制御機構２は特定の方位角方向に光束を絞り込む形状とはしない。
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the drawings illustrate the technical idea of the present invention, and the present invention is not limited to the matters described on the drawings.
FIG. 1 is a general view of the fish lamp of the present invention, FIG. 2 is a cross-sectional view of the plane A of FIG. 1, and FIG. 3 and FIG. The light source 1 by an electrodeless plasma lamp or a laser illumination device is installed on the top of the housing 5 with the light emitting part facing downward.
The light beam emitted from the light source is deflected horizontally in the elevation angle direction by the light distribution control mechanism 2 located below the light source. Further, the light distribution control mechanism 2 does not have a shape for narrowing the light flux in a specific azimuth direction.
この配光制御機構によって、図３に示す平面Ａにおける配光曲線のように、甲板の照射を抑制しながら、仰俯角方向には水平方向に光度のピークを有し、図４に示す平面Ｂにおける配光曲線のように方位角方向には広い範囲に光を放射する配光を実現する。
上記配光制御機構として、反射鏡の他、レンズを用いることや、これら任意の組み合わせも可能である。
光源から放射された光束は、筐体５の一部を構成する透明ガラスケース４を透過して海面上に到達する。筐体には、光源の駆動装置３が内蔵され、筐体の外側には光源１および駆動装置３から発生する熱を逃がすため、ヒートシンク６が設置される。筐体は、雨や海水から光源および駆動装置を保護するため、防水構造とする。
With this light distribution control mechanism, as shown in the light distribution curve in the plane A shown in FIG. 3, while suppressing the irradiation of the deck, the elevation angle direction has a light intensity peak in the horizontal direction, and the plane B shown in FIG. A light distribution that emits light in a wide range in the azimuth direction is realized as in the light distribution curve in FIG.
As the light distribution control mechanism, it is possible to use a lens in addition to a reflecting mirror, or any combination thereof.
The light beam emitted from the light source passes through the transparent glass case 4 constituting a part of the housing 5 and reaches the sea surface. A light source driving device 3 is built in the housing, and a heat sink 6 is installed outside the housing to release heat generated from the light source 1 and the driving device 3. The casing is waterproof to protect the light source and drive device from rain and seawater.
本発明では光源として無電極プラズマランプまたはレーザー照明装置を使用する。これら光源は、発光部は小さいが高輝度であるという特徴を有し、これらを用いることによって配光制御機構の単純化や、装置全体の小型化が可能となる。他方、無電極プラズマランプとレーザー照明装置から放射される光の分光分布には相違があり、メタルハライド光源の分光分布とも異なっている。 In the present invention, an electrodeless plasma lamp or a laser illumination device is used as the light source. These light sources have a feature that the light emitting part is small but has high luminance. By using these light sources, the light distribution control mechanism can be simplified and the entire apparatus can be downsized. On the other hand, there is a difference in the spectral distribution of the light emitted from the electrodeless plasma lamp and the laser illumination device, and the spectral distribution of the metal halide light source is also different.
具体的には、無電極プラズマランプは発光波長が広帯域にわたっているが（図５参照）、蛍光体変換方式のレーザー照明装置から放射された光の分光分布は（図６参照）、青色レーザー光で黄色の蛍光体を励起させて白色光を生成するため、白色ＬＥＤ光の分光分布（図７参照）に類似している。これらに対し、メタルハライド光源の分光分布は封入物に由来する複数のピークを有している（図８参照）。 Specifically, although the electrodeless plasma lamp has a broad emission wavelength (see FIG. 5), the spectral distribution of the light emitted from the phosphor conversion type laser illumination device (see FIG. 6) is blue laser light. Since the yellow phosphor is excited to generate white light, it is similar to the spectral distribution of white LED light (see FIG. 7). On the other hand, the spectral distribution of the metal halide light source has a plurality of peaks derived from the inclusion (see FIG. 8).
異なる光源の光に対するイカの反応を検証するため、水槽に収容したスルメイカに対し、メタルハライドランプに類似した分光特性を持つバラストレス水銀灯と無電極プラズマランプの光を、両者の発光強度を等しく調節して照射し、行動を比較する実験が行われている。
実験の結果、光源を横向きに設置して照射した場合、スルメイカ群はいずれの光源の場合でも、光源を設置したプラットフォームが形成する陰影の内部に滞留する傾向を示した（図９参照）。他方、光源を下向きに設置して照射した場合、いずれの光源でもスルメイカ群は陰影域と照射域の間を出入りし、照射域にも滞留した（図１０参照）。
以上に示すとおり、スルメイカの行動は光源の種類よりも光の向きに強く影響されることが知られている（松井萌ら（２０１５）プラズマ灯光に対するスルメイカの行動応答、スルメイカ資源評価協議会報告（平成２６年度）、 Ｐ. ３７-３８）。
In order to verify the response of squid to light from different light sources, the light intensity of both a ballastless mercury lamp and an electrodeless plasma lamp with spectral characteristics similar to those of a metal halide lamp are adjusted equally for a squid housed in a water tank. Experiments have been conducted to compare the behavior.
As a result of the experiment, when the light source was placed sideways and irradiated, the group of squids showed a tendency to stay inside the shadow formed by the platform on which the light source was installed (see FIG. 9). On the other hand, when the light source was placed downward and irradiated, the squid group entered and exited between the shaded area and the irradiated area with any light source and stayed in the irradiated area (see FIG. 10).
As shown above, it is known that the behavior of Japanese squid is more strongly influenced by the direction of light than the type of light source (Matsui Moe et al. (2015) Responses of Japanese squid to plasma lamp, 2014), P. 37-38).
図９および図１０は、これらの実験結果の模式図であるが、図９は光源を横向きに設置した場合のスルメイカ群の滞留位置を示し、図１０は光源を下向き設置した場合のスルメイカ群の滞留位置を示すものである。
また、イカ釣り漁船の集魚灯として、発光ダイオードを光源としたものの使用が始まっているが、従来型のメタルハライド集魚灯と同様の海面照度分布を白色発光ダイオード集魚灯で再現してイカ釣り操業を行った場合、両者の漁獲能力はほぼ同等となることが知られている（国立研究開発法人水産総合研究センター開発調査センター（２０１５）、海洋水産資源開発ニュース Ｎｏ. ４３４）。
FIG. 9 and FIG. 10 are schematic diagrams of these experimental results. FIG. 9 shows the staying position of the squid group when the light source is installed sideways, and FIG. 10 shows the squid group when the light source is installed downward. This indicates the staying position.
In addition, the use of light emitting diodes as a light source for squid fishing fishing boats has begun to be used, but the illuminance distribution similar to that of conventional metal halide fishery lights is reproduced with white light emitting diode fishery lamps for squid fishing operations. It is known that the fishing capacities of the two will be almost the same (National Fisheries Research Center Development Research Center (2015), Marine Fisheries Resources Development News No. 434).
以上のことから、発光波長がある程度広帯域であれば、これら光源、すなわちメタルハライドランプ、無電極プラズマランプ、蛍光体変換方式のレーザー照明装置、白色発光ダイオードは、集魚灯装置の光源として、互に交換可能であると考えられ、高効率の光源を用いることによって、少ないエネルギー消費量で同等の漁獲能力を得ることが期待される。 From the above, if the emission wavelength is a certain range, these light sources, ie metal halide lamp, electrodeless plasma lamp, phosphor conversion laser lighting device, and white light emitting diode, are interchanged as the light source of the fish collection lamp device. It is considered possible, and by using a highly efficient light source, it is expected to obtain the same catching capacity with low energy consumption.
本発明によって実現される配光は、天空および甲板方向の照射を抑制すること、仰俯角方向には水平方向にピークを持つこと、方位角方向には特定の方向に配光を絞り込まず、光源から放射された光束を拡散させることを特徴とする。これら特徴は、無駄に照射されて集魚に寄与しない光束を偏向し、海面方向へ振り向けることで照射効率を向上させることをねらいとしている。 The light distribution realized by the present invention suppresses irradiation in the sky and deck directions, has a peak in the horizontal direction in the elevation angle direction, and does not narrow the light distribution in a specific direction in the azimuth angle direction. It is characterized by diffusing the light beam emitted from the. These characteristics aim to improve the irradiation efficiency by deflecting the light beam that is irradiated unnecessarily and does not contribute to the fish collection and directing it toward the sea surface.
しかし、配光制御によって光束を絞り込み、光軸を海面に向けることによって、さらに照射効率を向上することができる半面、照射範囲が狭くなり、広い範囲からイカを集める機能を失うことになる。既往の知見では、スルメイカは２海里程度の距離からも集魚灯の光に誘引されることが知られており（高尾芳三 （２０１３）「漁灯は広範囲からイカを集めている」水産工学研究所ほか編、イカ釣りＬＥＤ漁灯活用ガイド Ｐ. １４-１５）、広い範囲からの集魚を可能とするため、方位角方向には、可能な限り配光を絞り込まないことが望ましい。 However, by narrowing the light flux by light distribution control and directing the optical axis to the sea surface, the irradiation efficiency can be further improved. On the other hand, the irradiation range is narrowed, and the function of collecting squid from a wide range is lost. According to previous knowledge, squid are attracted to the light of the fishing light even from a distance of about 2 nautical miles (Yoshizo Takao (2013) “Fishing light collects squid from a wide area”. Others, Squid Fishing LED Fishing Light Utilization Guide P. 14-15), it is desirable not to narrow the light distribution as much as possible in the azimuth direction in order to enable fish collection from a wide range.
また、遠方のイカに対する集魚効果を期するため、仰俯角方向の配光のピークは水平方向とすべきである。既存の技術であるメタルハライド集魚灯および発光ダイオード集魚灯においても、漁船に艤装する際には配光のピークが水平方向を向くよう設置されるのが一般的である。 In addition, the peak of the light distribution in the elevation angle direction should be in the horizontal direction in order to achieve a fish collection effect on distant squid. In existing metal halide and light-emitting diode fishing lights, which are existing technologies, the light distribution peak is generally installed so that the peak of the light distribution faces in the horizontal direction when equipping a fishing boat.
以下に、上記形態によって実現する集魚灯装置を用いた場合の実施例として、１９トン型の小型イカ釣り漁船の集魚灯をメタルハライドランプから本発明に置き換えた場合の効果について、光学シミュレーションの結果に基づいて記述する。 In the following, as an example of using a fishlight device realized by the above-described embodiment, the effect of replacing the fishlight of a 19-ton type small squid fishing fishing boat with a metal halide lamp according to the present invention is the result of optical simulation. Describe based on.
典型的な１９トン型の小型イカ釣り漁船は、消費電力３ｋＷのメタルハライド集魚灯を５３本装備し、前灯を点灯した場合の消費電力は１５９ｋＷとなる。メタルハライド集魚灯1本から放射される光エネルギーの総和である全放射束を１，０８０Ｗとすると、システム全体では放射束は５７，２４０Ｗとなる（図１１Ａ）。
この放射束のうち、船体を中心とした２００ｍ四方の海面に到達する放射束の量をモンテカルロ法によりシミュレーションしたところ、システム全体の放射束の約１６％に相当する９，０２６Ｗであると試算された（図１１Ｂ）。
A typical 19-ton small squid fishing fishing boat is equipped with 53 metal halide fishing lights with a power consumption of 3 kW, and the power consumption when the front lights are turned on is 159 kW. Assuming that the total radiant flux, which is the sum of light energy emitted from one metal halide fishing lamp, is 1,080 W, the radiant flux is 57,240 W in the entire system (FIG. 11A).
Of these radiant fluxes, the amount of radiant flux reaching the 200m square sea surface centered on the hull was simulated by the Monte Carlo method. (FIG. 11B).
本発明による集魚灯の実施例として、無電極プラズマランプを光源とした、消費電力約０．５ｋＷ、全放射束約１２８Ｗの集魚灯を用いた際の効果を前述の方法と同様にシミュレーションした。当該集魚灯は、海面へ到達する放射束の割合が高く、約７６％の放射束が海面に到達すると試算された。前述のメタルハライド集魚灯と同量の放射束を海面に到達させるには、９５台の本発明による集魚灯が必要で、システム全体の放射束は１２，１１９Ｗ（図１１Ｃ）、うち海面に到達する放射束は９，１９０Ｗとなる（図１１Ｄ）。 As an example of the fish collection lamp according to the present invention, the effect of using a fish collection lamp with an electrodeless plasma lamp as a light source and a power consumption of about 0.5 kW and a total radiant flux of about 128 W was simulated in the same manner as described above. The fishlight has a high ratio of radiant flux reaching the sea surface, and it is estimated that approximately 76% of the radiant flux reaches the sea surface. In order to reach the sea surface with the same amount of radiant flux as that of the metal halide fish lamp described above, 95 fish lamps according to the present invention are required, and the radiant flux of the entire system is 12,119 W (FIG. 11C), of which the sea surface is reached. The radiant flux is 9,190 W (FIG. 11D).
上記事例の無電極プラズマランプ集魚灯を全て点灯した場合の消費電力は４７．５ｋＷとなる。以上のことから、上記のメタルハライド集魚灯と比較して約１／３の電力で、同等の漁獲能力を実現することが期待される。シミュレーションによる試算では、パネル状の発光ダイオード集魚灯では、放射束の海面到達率は３０％程度と試算されており、これと比較しても本発明による集魚灯は高効率であるといえる。 The power consumption when all of the electrodeless plasma lamps in the above case are turned on is 47.5 kW. From the above, it is expected that the same catching ability will be realized with about 1/3 of the electric power compared to the above metal halide fishing lights. In the trial calculation by simulation, the panel-like light-emitting diode fishing lamp has been estimated to have a sea surface arrival rate of radiant flux of about 30%. Compared with this, it can be said that the fishing lamp according to the present invention is highly efficient.
本発明は少ない消費電力で従来型集魚灯と同様の効果をもたらすものであり、イカ釣り漁業の支出において大きな割合を占める燃料費を削減し、経営改善に資する効果がある。また、機器を比較的コンパクトに設計できることから、甲板上への艤装が容易であり、重心の低下や風圧抵抗の減少など、漁船の安全性の向上にも寄与する。 The present invention brings about the same effect as a conventional fish-collecting light with low power consumption, and has the effect of reducing the fuel cost, which accounts for a large proportion of the expenditure in the squid fishing fishery, and contributing to management improvement. In addition, since the equipment can be designed relatively compactly, it can be easily equipped on the deck, contributing to the improvement of fishing boat safety, such as lowering the center of gravity and reducing wind pressure resistance.
