Description

本発明は、捕獲の対象を捕獲可能な領域に誘い込むべく釣船や漁船等の船舶に取り付けられる集魚灯及び該集魚灯を備えた船舶に関する。   The present invention relates to a fish collecting lamp attached to a vessel such as a fishing boat or a fishing boat in order to invite an object to be captured to a catchable region, and a vessel provided with the fish collecting light.

従来から、漁獲高を高める方法として種々の方法が提案されており、その一つとして船舶に取り付けた集魚灯で水面（海面）に光を照射し、その光によって捕獲の対象（例えば、ニシン、鰯、鰺、サンマ等の各種魚や、イカ、カニ、エビ類等）を捕獲可能な領域に誘い込む方法が知られている。   Conventionally, various methods have been proposed as methods for increasing catch, and as one of them, light is applied to the surface of the water (sea surface) with a fishing light attached to a ship, and the target of capture (for example, herring, There are known methods for attracting fish such as sea bream, sea bream, saury, squid, crabs, shrimps, etc.) to a catchable area.

かかる方法に用いられる集魚灯は、光源と、該光源を取り付けるためのソケットとを備えている。前記光源は、一般的にメタルハライドランプ等の電球が採用されており、船舶（船体）上に設けられた支持材（例えば、船体の全長方向に延びるように架設されたワイヤーや棒材等）に取り付けられたソケットに電気的に接続することで、発光部（バルブ）全体が露呈した状態になるように構成されている（例えば、特許文献１参照）。   A fish lamp used in such a method includes a light source and a socket for mounting the light source. The light source generally employs a light bulb such as a metal halide lamp, and is used as a support material provided on a ship (hull) (for example, a wire or a bar laid so as to extend in the full length direction of the hull). By being electrically connected to the attached socket, the entire light emitting unit (bulb) is exposed (see, for example, Patent Document 1).

上記構成の集魚灯は、船舶の左舷側と右舷側とに船体の全長方向に間隔をあけて複数配置される。これにより、船舶の略全体からその周囲の水面を照らすことができるため、網や釣竿等の漁具によって捕獲可能な領域内に捕獲の対象を光で誘い込むことができる。   A plurality of fishlights having the above-described configuration are arranged on the port side and starboard side of the ship at intervals in the full length direction of the hull. Thereby, since the water surface of the circumference | surroundings can be illuminated from the substantially whole ship, the target of capture can be drawn in by light in the area | region which can be captured with fishing gear, such as a net and a fishing rod.

ところで、従来の集魚灯は、上述の如く、光源に発光効率の高いメタルハライドランプ等の電球が採用されているため、集魚に必要な照度を十分に得ることができるが、電球のバルブ（発光部）全体を露呈させたものであるため、発光部で発光させた光が水面だけでなく集魚に関係のない上空に向けても放射され、供給した電力を無駄に消費してしまうといった問題がある。特に、燃料高騰が激しい近年においては、漁獲高（売り上げ）と操業費用（船舶及び発電機を駆動するための燃料費）とのバランスがとれず、各地において出航を取りやめるといった事態も発生しており、燃料消費の増大に繋がる電力の無駄な消費は漁師や船宿等の死活問題に繋がる大きな問題である。   By the way, as described above, the conventional fish collection light employs a light source such as a metal halide lamp with high luminous efficiency as the light source, so that sufficient illuminance necessary for fish collection can be obtained. ) Since the whole is exposed, there is a problem that the light emitted from the light emitting part is emitted not only to the water surface but also to the sky not related to fish collection, and wastes the supplied power . In particular, in recent years when fuel prices have been soaring, there has been a situation in which the balance between fishing volume (sales) and operating costs (fuel costs for driving ships and generators) is not balanced, and sailings have been canceled in various locations. The wasteful consumption of electricity that leads to an increase in fuel consumption is a major problem that leads to life and death problems for fishermen and boat houses.

このような現状から、消費電力の少ないＬＥＤを光源とする集魚灯が提案されている（例えば、特許文献２参照）。かかる集魚灯は、多数のＬＥＤをパネル上に配置したもので、全てのＬＥＤを同時に発光させることで、集魚に必要な照度を得るようになっている。   From such a current situation, a fish collecting lamp using an LED with low power consumption as a light source has been proposed (see, for example, Patent Document 2). Such a fish collection lamp has a large number of LEDs arranged on a panel, and illuminance necessary for fish collection is obtained by causing all the LEDs to emit light simultaneously.

日本国特開平９−０２２６８３号公報Japanese Unexamined Patent Publication No. 9-022683 日本国特開２００３−１３４９６７号公報Japanese Unexamined Patent Publication No. 2003-134967

しかしながら、ＬＥＤを光源とする集魚灯は、ＬＥＤの１球当りの照度（発光量）が非常に小さいため、電球のバルブ（発光部）全体を露呈させた集魚灯と同レベルの照度にするには、多数のＬＥＤが必要となり、集魚灯１基当りのサイズが大きくなってしまう。   However, the fish-collecting light that uses LEDs as the light source has a very small illuminance (amount of light emission) per bulb of the LED, so the illuminance is the same level as the fish-collecting light that exposes the entire bulb (light-emitting part) of the bulb. Requires a large number of LEDs, resulting in an increase in the size per fish collection lamp.

そのため、船舶上に配置できる集魚灯の数が減ってしまうことになり、電球のバルブ（発光部）全体を露呈させた集魚灯を船舶に複数設けたときの照度を確保することができず、結果として満足できる集魚効率が得られないといった問題がある。また、多数のＬＥＤを配置するのにパネルが大きくなりすぎると、操舵室からの視界を遮るだけでなく、横風に煽られる原因となるため安全航行を妨げるといった問題がある。   Therefore, the number of fish collection lights that can be arranged on the ship will be reduced, and it is not possible to secure the illuminance when providing a plurality of fish collection lights that expose the entire bulb (light emitting part) of the bulb, As a result, there is a problem that satisfactory fish collection efficiency cannot be obtained. Further, if the panel becomes too large to arrange a large number of LEDs, there is a problem that not only the view from the wheelhouse is obstructed but also a safe wind is obstructed because it causes a cross wind.

そこで、本発明は、斯かる実情に鑑み、少ない消費電力で優れた集魚効果が得られる集魚灯及び該集魚灯を備えた船舶を提供することを課題とする。   Therefore, in view of such a situation, an object of the present invention is to provide a fish collecting lamp capable of obtaining an excellent fish collecting effect with less power consumption and a ship equipped with the fish collecting lamp.

本発明に係る集魚灯は、船体上に設けられた支持材に対して取付可能に構成された取付手段と、２つ以上の光源と、前記取付手段に連設されるとともに各光源を保持可能に構成された保持手段とを備え、各光源は、取付手段が支持材に取り付けられた状態で上下方向となる一方向に真っ直ぐに延びる仮想軸に対して交差する方向に光軸が延びるように設けられていることを特徴とする。   The fish lamp according to the present invention is provided with an attachment means configured to be attachable to a support member provided on a hull, two or more light sources, and connected to the attachment means and capable of holding each light source. And each light source has an optical axis extending in a direction intersecting with a virtual axis extending straight in one direction which is the vertical direction in a state where the mounting means is attached to the support member. It is provided.

上記構成の集魚灯は、船舶上に設けられた支持材に取付手段を取り付けた状態で、保持手段に保持された２つ以上の光源の光軸が上下方向（仮想軸）と交差する方向に延びた状態になり、各光源で水面上を照らすことができる。このように各光源が水面のみを照らすことができるため、各光源からの光が捕獲の対象を誘い込む領域以外に無駄に放射されることがなく、光源に対して供給した電力を集魚のために有効に活用することができる。   The fishlight having the above-mentioned configuration is such that the optical axes of two or more light sources held by the holding means intersect the vertical direction (virtual axis) in a state where the attaching means is attached to a support material provided on the ship. It becomes the extended state and can illuminate the surface of the water with each light source. Since each light source can illuminate only the water surface in this way, light from each light source is not radiated wastefully outside the area that attracts the target of capture, and the power supplied to the light source is collected for fish collection It can be used effectively.

これにより、上記構成の集魚灯は、光の照射を必要としない上空にまで光を放射（四方八方に光を放射）する従来の集魚灯よりも消費電力を抑えた上で良好な集魚効果を得ることができる。なお、上記構成の集魚灯は、上述の如く、消費電力を抑えることを目的としているが、例えば、燃料価格の低下等で発電機からの電力量を従来の集魚灯と同様の電力量にすることが許される場合には、従来の集魚灯と同様の電力供給をすることで、捕獲の対象を誘い込む領域に照射する照度（光量）を従来の集魚灯よりも大きくすることができ、集魚効果をさらに高めることができる。   As a result, the fish collection lamp configured as described above has a better fish collection effect while reducing power consumption than a conventional fish collection lamp that radiates light to the sky that does not require light irradiation (radiates light in all directions). Obtainable. Note that the fishlight with the above configuration is intended to reduce power consumption as described above. For example, the amount of power from the generator is reduced to the same amount as that of a conventional fishlight due to a decrease in fuel prices. If this is permitted, the same illuminance (light intensity) applied to the area that attracts the target to be captured can be increased compared to the conventional fish light by supplying the same power as the conventional fish light. Can be further enhanced.

そして、耐熱性に優れた高価な石英ガラスでバルブ（外球）が形成された電球等を光源に採用しても勿論よいが、上述の如く、消費電力が抑えられることで、各光源に低電力（低ワット）のものを採用して各光源の発光時における発熱温度を低くすることができるため、比較的低価格な汎用の電球を光源の発光部として採用することができる。なお、各光源には、指向性を有するもの、例えば、電球（発光部）とは別に反射構造（反射傘）が設けられたもの（例えば、投光器）を採用することができるが、大きさや重さを考慮すると、電球のバルブの内面にアルミ蒸着膜等の反射膜が形成された軽量で且つコンパクトなものを採用することが好ましい。   Of course, a light bulb or the like in which a bulb (outer bulb) is formed of expensive quartz glass with excellent heat resistance may be used as the light source. Since the heat generation temperature at the time of light emission of each light source can be lowered by adopting a power (low watt) one, a relatively low-cost general-purpose light bulb can be adopted as the light emitting part of the light source. For each light source, a light source having a directivity, for example, a light source (light emitting unit) provided with a reflecting structure (a reflector) (for example, a projector) can be used. In view of this, it is preferable to adopt a lightweight and compact one in which a reflective film such as an aluminum vapor deposition film is formed on the inner surface of the bulb of the bulb.

本発明の一態様として、前記２つ以上の光源は、互いの照射領域が一列に並ぶように設けられてもよい。このようにすれば、各光源の照射領域が連なって船舶に近い領域から遠方に向けて光を照射することができる。これにより、船舶が横揺れした場合（ローリングした場合）でも、船舶から所定の範囲（船舶から捕獲の対象を捕獲できる領域）に光を照射することができ、船舶周りに捕獲の対象を定常的に誘い込むことができる。   As one aspect of the present invention, the two or more light sources may be provided such that their irradiation regions are arranged in a line. If it does in this way, the irradiation area | region of each light source will continue, and it can irradiate light to the distance from the area | region near a ship. As a result, even when the ship rolls (rolls), it is possible to irradiate light from the ship to a predetermined range (an area in which the capture target can be captured from the ship), and the capture target is stationary around the ship. You can lure into.

また、本発明の他態様として、前記２つ以上の光源は、互いの照射領域が略一致するように設けられてもよい。このようにすれば、２つ以上の光源のそれぞれの光が同一領域に照射されることになるため、その領域内での照度が増すことになり、集魚効果を高めることができる。   Moreover, as another aspect of the present invention, the two or more light sources may be provided so that their irradiation areas substantially coincide with each other. If it does in this way, since each light of two or more light sources will be irradiated to the same field, the illuminance in the field will increase and the fish collection effect can be heightened.

本発明の別の態様として、各光源は、前記仮想軸及び光軸と直交又は略直交する軸線周りで回転可能に設けられていることが好ましい。このようにすれば、各光源の光軸の角度を変更することができるため、照射領域を適正な位置に適宜調整することができる。   As another aspect of the present invention, each light source is preferably provided so as to be rotatable around an axis orthogonal to or substantially orthogonal to the virtual axis and the optical axis. In this way, since the angle of the optical axis of each light source can be changed, the irradiation region can be appropriately adjusted to an appropriate position.

本発明のさらに別の態様として、前記保持手段は、前記仮想軸と交差する方向に延びるレバー部を備え、該レバー部には、各光源を保持する保持位置が長手方向に間隔をあけて設定されていることが好ましい。このようにすれば、２つ以上の光源を設けても、これらが真っ直ぐ下方に連なることがない。これにより、船舶の操舵室の前方に複数の集魚灯が配設されても操舵室からの視界を確保することができ、安全航行に貢献することができる。   As still another aspect of the present invention, the holding means includes a lever portion extending in a direction intersecting the virtual axis, and a holding position for holding each light source is set at an interval in the longitudinal direction in the lever portion. It is preferable that In this way, even if two or more light sources are provided, they do not continue straight down. Thereby, even if a plurality of fish-collecting lights are disposed in front of the ship's wheelhouse, the field of view from the wheelhouse can be ensured, contributing to safe navigation.

そして、本発明に係る船舶は、船体上に設けられた支持材に対して集魚灯が取り付けられた船舶であって、前記集魚灯が上記の何れかであることを特徴とする。かかる船舶によれば、保持手段に保持された２つ以上の光源の光軸が上下方向（仮想軸）と交差する方向に延びた状態になり、各光源で水面上を照らすことができる。このように各光源が水面のみを照らすことができるため、各光源からの光が捕獲の対象を誘い込む領域以外に無駄に放射されることがなく、光源に対して供給した電力を集魚のために有効に活用することができる。   And the ship which concerns on this invention is a ship by which the fish collection light was attached with respect to the support material provided on the hull, Comprising: The said fish collection light is any one of the above. According to such a ship, the optical axes of two or more light sources held by the holding means extend in a direction intersecting the vertical direction (virtual axis), and each light source can illuminate the water surface. Since each light source can illuminate only the water surface in this way, light from each light source is not radiated wastefully outside the area that attracts the target of capture, and the power supplied to the light source is collected for fish collection It can be used effectively.

これにより、上記構成の集魚灯は、光の照射を必要としない上空にまで光を放射（四方八方に光を放射）する従来の集魚灯よりも消費電力を抑えた上で良好な集魚効果を得ることができる。なお、上記構成の集魚灯は、上述の如く、消費電力を抑えることを目的としているが、例えば、燃料価格の低下等で発電機からの電力量を従来の集魚灯と同様の電力量にすることが許される場合には、従来の集魚灯と同様の電力供給をすることで、捕獲の対象を誘い込む領域に照射する照度（光量）を従来の集魚灯よりも大きくすることができ、集魚効果をさらに高めることができる。   As a result, the fish collection lamp configured as described above has a better fish collection effect while reducing power consumption than a conventional fish collection lamp that radiates light to the sky that does not require light irradiation (radiates light in all directions). Obtainable. Note that the fishlight with the above configuration is intended to reduce power consumption as described above. For example, the amount of power from the generator is reduced to the same amount as that of a conventional fishlight due to a decrease in fuel prices. If this is permitted, the same illuminance (light intensity) applied to the area that attracts the target to be captured can be increased compared to the conventional fish light by supplying the same power as the conventional fish light. Can be further enhanced.

そして、耐熱性に優れた高価な石英ガラスでバルブ（外球）が形成された電球等を光源に採用しても勿論よいが、上述の如く、消費電力が抑えられることで、各光源に低電力（低ワット）のものを採用して各光源の発光時における発熱温度を低くすることができるため、比較的低価格な汎用の電球を光源の発光部として採用することができる。なお、各光源には、指向性を有するもの、例えば、電球（発光部）とは別に反射構造（反射傘）が設けられたもの（例えば、投光器）を採用することができるが、大きさや重さを考慮すると、電球のバルブの内面にアルミ蒸着膜等の反射膜が形成された軽量で且つコンパクトなものを採用することが好ましい。   Of course, a light bulb or the like in which a bulb (outer bulb) is formed of expensive quartz glass with excellent heat resistance may be used as the light source. Since the heat generation temperature at the time of light emission of each light source can be lowered by adopting a power (low watt) one, a relatively low-cost general-purpose light bulb can be adopted as the light emitting part of the light source.

In view of this, it is preferable to adopt a lightweight and compact one in which a reflective film such as an aluminum vapor deposition film is formed on the inner surface of the bulb of the bulb.

そして、互いの照射領域が一列に並ぶように２つ以上の光源が設けられた場合には、各光源の照射領域が連なって船舶に近い領域から遠方に向けて光を照射することができる。これにより、船舶が横揺れした場合（ローリングした場合）でも、船舶から所定の範囲（船舶から捕獲の対象を捕獲できる領域）に光を照射することができ、船舶周りに捕獲の対象を定常的に誘い込むことができる。   And when two or more light sources are provided so that each other's irradiation area | regions are located in a line, the irradiation area | region of each light source continues and it can irradiate light from the area | region close | similar to a ship to a distant place. As a result, even when the ship rolls (rolls), it is possible to irradiate light from the ship to a predetermined range (an area in which the capture target can be captured from the ship), and the capture target is stationary around the ship. You can lure into.

また、互いの照射領域が略一致するように２つ以上の光源が設けられた場合には、２つ以上の光源のそれぞれの光が同一領域に照射されることになるため、その領域内での照度が増すことになり、集魚効果を高めることができる。   In addition, when two or more light sources are provided so that their irradiation areas substantially coincide with each other, the light of each of the two or more light sources is emitted to the same area. The illuminance of the fish will increase, and the fish collection effect can be enhanced.

そして、各光源は、前記仮想軸及び光軸と直交又は略直交する軸線周りで回転可能に設けられている場合には、各光源の光軸の角度を変更することがでるため、照射領域を適正な位置に適宜調整することができる。   When each light source is provided so as to be rotatable around an axis that is orthogonal or substantially orthogonal to the virtual axis and the optical axis, the angle of the optical axis of each light source can be changed. It can be appropriately adjusted to an appropriate position.

また、前記保持手段は、前記仮想軸と交差する方向に延びるレバー部を備え、該レバー部に各光源を保持する保持位置が長手方向に間隔をあけて設定されている場合には、２つ以上の光源を設けても、これらが真っ直ぐ下方に連なることがない。これにより、船舶の操舵室の前方に複数の集魚灯が配設されても操舵室からの視界を確保することができ、安全航行に貢献することができる。   The holding means includes a lever portion extending in a direction intersecting with the virtual axis, and when the holding position for holding each light source in the lever portion is set with an interval in the longitudinal direction, two holding portions are provided. Even if the above light sources are provided, they do not continue straight down. Thereby, even if a plurality of fish-collecting lights are disposed in front of the ship's wheelhouse, the field of view from the wheelhouse can be ensured, contributing to safe navigation.

以上のように、本発明に係る集魚灯は、少ない消費電力で優れた集魚効果が得られるという優れた効果を奏し得る。また、本発明に係る船舶についても、少ない消費電力で優れた集魚効果が得られるという優れた効果を奏し得る。   As described above, the fish collection lamp according to the present invention can exhibit an excellent effect that an excellent fish collection effect can be obtained with low power consumption. Moreover, the marine vessel according to the present invention can also have an excellent effect that an excellent fish collection effect can be obtained with low power consumption.

以下、本発明の第一実施形態について、添付図面を参照しつつ説明する。   Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

図１に示す如く、本実施形態に係る集魚灯１は、漁船や釣船等の船舶Ｂの船体Ｂａ上に設けられた支持材Ｗに取り付けられるもので、一般的には船体Ｂａの全長方向に複数設けられる。そして、本実施形態に係る集魚灯１は、支持材Ｗに取り付けられることを前提に、図２、及び図３に示す如く、船体Ｂａ上に設けられた支持材Ｗに対して取付可能に構成された取付手段１０と、２つ以上（本実施形態においては２つ）の光源２０，３０と、前記取付手段１０に連設されるとともに各光源２０，３０を保持可能に構成された保持手段４０とを備えている。   As shown in FIG. 1, a fish collection lamp 1 according to the present embodiment is attached to a support material W provided on a hull Ba of a boat B such as a fishing boat or a fishing boat, and generally in the full length direction of the hull Ba. A plurality are provided. The fish lamp 1 according to the present embodiment is configured to be attachable to the support material W provided on the hull Ba as shown in FIGS. 2 and 3 on the assumption that the fishlight 1 is attached to the support material W. Mounting means 10, two or more (in this embodiment, two) light sources 20, 30, and holding means connected to the mounting means 10 and configured to hold each of the light sources 20, 30. 40.

本実施形態に係る取付手段１０は、支持材Ｗが船体Ｂａ上に架設された索条（ワイヤーＷ）であることを前提に構成されている。具体的には、取付手段１０は、図２、図３（ａ）及び図４に示す如く、ベース１００と、該ベース１００に対向して配置される片部材１０１，１０２と、片部材１０１，１０２をベース１００に固定する固定手段１０３とを備えている。   The attachment means 10 according to the present embodiment is configured on the assumption that the support material W is a rope (wire W) installed on the hull Ba. Specifically, as shown in FIG. 2, FIG. 3A and FIG. 4, the attaching means 10 includes a base 100, piece members 101, 102 arranged to face the base 100, piece pieces 101, Fixing means 103 for fixing 102 to the base 100 is provided.

前記ベース１００は、四角形状をなす板状のベース本体１００ａと、ベース本体１００ａの両端から該ベース本体１００ａの一方の面側に延出する一対の補強部１００ｂ，１００ｂとを備えている。該ベース１００は、一枚の板材を折り曲げ加工することにより前記ベース本体１００ａ及び一対の補強部１００ｂ，１００ｂが形成されている。   The base 100 includes a plate-shaped base body 100a having a quadrangular shape, and a pair of reinforcing portions 100b and 100b extending from both ends of the base body 100a to one surface side of the base body 100a. The base 100 is formed with a base body 100a and a pair of reinforcing portions 100b and 100b by bending a single plate material.

そして、前記ベース本体１００ａには、固定手段としてのネジ１０３を螺嵌するためのネジ穴Ｓ１が設けられている。本実施形態においては、ベース本体１００ａの両端部に複数のネジ穴Ｓ１…が間隔をあけて一列に形成されている。これに対し、各補強部１００ｂ，１００ｂには、前記保持手段４０（後述するアーム部材４０ａ）を連結するためネジＢ１を螺合するためのネジ穴Ｓ２が設けられている。   The base body 100a is provided with a screw hole S1 for screwing a screw 103 as a fixing means. In the present embodiment, a plurality of screw holes S1... Are formed in a row at both ends of the base body 100a with a gap therebetween. On the other hand, each reinforcing portion 100b, 100b is provided with a screw hole S2 for screwing a screw B1 to connect the holding means 40 (an arm member 40a described later).

前記片部材１０１，１０２は、短冊状の板材で構成されており、ベース本体１００ａのネジ穴Ｓ１…の配置と対応するように、長手方向に間隔をあけて複数の貫通穴Ｈ１…が穿設されている。各貫通穴Ｈ１…は、固定手段としてのネジ１０３を挿通できるサイズに設定されている。   The piece members 101 and 102 are formed of a strip-shaped plate material, and a plurality of through holes H1 are formed at intervals in the longitudinal direction so as to correspond to the arrangement of the screw holes S1 of the base body 100a. Has been. Each through hole H1... Is set to a size that allows a screw 103 as a fixing means to be inserted.

これにより、本実施形態に係る取付手段１０は、ベース１００と片部材１０１，１０２とで支持材（ワイヤー）Ｗを挟み込んだ状態で、片部材１０１，１０２の貫通穴Ｈ１に挿通したネジ１０３をベース本体１００ａのネジ穴Ｓ１に螺合して締め付けることで、船舶Ｂの船体Ｂａ上に架設されたワイヤーＷに取り付けることができるようになっている。   Thereby, the attachment means 10 which concerns on this embodiment has the screw 103 inserted in the through-hole H1 of the piece member 101,102 in the state which pinched | interposed the support material (wire) W with the base 100 and the piece member 101,102. By screwing and tightening into the screw hole S1 of the base body 100a, the base body 100a can be attached to the wire W installed on the hull Ba of the ship B.

各光源２０，３０は、図２及び図３に示す如く、取付手段１０が支持材Ｗに取り付けられた状態で上下方向となる一方向に真っ直ぐに延びる仮想軸に対して交差する方向に光軸Ｒ１，Ｒ２が延びるように設けられている。なお、図２及び図３（ｂ）において、一方向に真っ直ぐに延びる仮想軸を縦軸（Ｙ軸）として一点鎖線で示しているため、以下の説明において、便宜状、仮想軸をＹ軸ということとする。   As shown in FIGS. 2 and 3, each light source 20 and 30 has an optical axis in a direction intersecting with a virtual axis extending straight in one direction which is the vertical direction in a state where the attachment means 10 is attached to the support member W. R1 and R2 are provided to extend. In FIG. 2 and FIG. 3B, a virtual axis extending straight in one direction is indicated by a one-dot chain line as a vertical axis (Y axis). Therefore, in the following description, for convenience, the virtual axis is referred to as a Y axis. I will do it.

本実施形態においては、各光源２０，３０は、光軸Ｒ１，Ｒ２がＹ軸と平行又は略平行な共通の仮想平面（図示しない）に沿うように一列に配置されている。すなわち、本実施形態に係る集魚灯１は、２つの光源２０，３０が上下方向乃至前後方向で一列（二段）に配置されている。   In the present embodiment, the light sources 20 and 30 are arranged in a line so that the optical axes R1 and R2 are along a common virtual plane (not shown) that is parallel or substantially parallel to the Y axis. That is, in the fish lamp 1 according to the present embodiment, the two light sources 20 and 30 are arranged in a line (two stages) in the vertical direction or the front-rear direction.

このように光源２０，３０を一列に配置することで、１基当りの集魚灯１の設置スペース（Ｙ軸と光軸Ｒ１，Ｒ２と直交する方向：幅方向のサイズ）が小さくなるため、船体Ｂａの全長方向で集魚灯１を横並びに設置できる数を多くすることができるようになっている。すなわち、集魚灯１を船舶Ｂに取り付けた状態で船舶Ｂの全長方向と一致する方向に光源２０，３０を横並びに配置すると、集魚灯１の幅方向のサイズが大きくなってしまう。そのため、船体Ｂａ上に設置できる集魚灯１の数が減ってしまうが、本実施形態に係る集魚灯１は、船舶Ｂ上で横並びに配置する方向（船舶Ｂの全長方向）と直交する方向となる軸線方向に２つの光源２０，３０を一列で配置することで、集魚灯１の幅方向のサイズが最小限になっており、船舶Ｂａ上といった限られたスペースに、より多くの集魚灯１を設置することができるようになる。   By arranging the light sources 20 and 30 in a row in this manner, the installation space for the fish lamps 1 per unit (the direction perpendicular to the Y axis and the optical axes R1 and R2: the size in the width direction) is reduced. It is possible to increase the number of fish lamps 1 that can be installed side by side in the full length direction of Ba. That is, if the light sources 20 and 30 are arranged side by side in a direction that coincides with the full length direction of the boat B with the fish lamp 1 attached to the boat B, the size of the fish lamp 1 in the width direction is increased. Therefore, although the number of the fish collection lamps 1 that can be installed on the hull Ba is reduced, the fish collection lamp 1 according to the present embodiment has a direction orthogonal to the direction (the full length direction of the ship B) arranged side by side on the ship B. By arranging the two light sources 20 and 30 in a line in the axial direction, the size of the fishlight lamp 1 in the width direction is minimized, and more fishlight lamps 1 are provided in a limited space on the ship Ba. Can be installed.

そして、本実施形態において、各光源２０，３０は、それぞれの照射領域が一列に並ぶように設けられている。すなわち、図６に示す如く、２つの光源２０，３０の照射領域Ａ１，Ａ２が連なるように、一方の光源２０は、船体側を照射する一方、他方の光源３０は、一方の光源２０よりも遠方を照射するようにそれぞれ角度設定される。   And in this embodiment, each light source 20 and 30 is provided so that each irradiation region may be located in a line. That is, as shown in FIG. 6, one light source 20 irradiates the hull side so that the irradiation areas A1 and A2 of the two light sources 20 and 30 are continuous, while the other light source 30 is more than the one light source 20. Each angle is set so as to irradiate far away.

そして、本実施形態に係る集魚灯１は、各光源２０，３０が前記Ｙ軸及び光軸Ｒ１，Ｒ２と直交又は略直交する軸線周りで回転可能に設けられており、取り付け時に上下方向となるＹ軸に対する光軸Ｒ１，Ｒ２の角度θ１，θ２を調整できるようになっている。   In the fish lamp 1 according to the present embodiment, the light sources 20 and 30 are provided so as to be rotatable about axes that are orthogonal or substantially orthogonal to the Y axis and the optical axes R1 and R2, and are vertically oriented when attached.

そして、各保持手段４０のレバー部４００，４００の貫通穴に挿通したネジＢ２を光源２０，３０（光源本体２００，３００のネジ穴）に螺合することで、各光源２０，３０が両側から挟み込まれた状態で保持されている。これにより、各光源２０，３０は、レバー部４００の長手方向に間隔をあけて一列に配置されている。   Then, the screws B2 inserted through the through holes of the lever portions 400, 400 of the holding means 40 are screwed into the light sources 20, 30 (screw holes of the light source bodies 200, 300), so that the light sources 20, 30 are viewed from both sides. It is held in a sandwiched state. Thereby, each light source 20 and 30 is arrange | positioned at intervals in the longitudinal direction of the lever part 400 at 1 row.

また、アーム部材４０ａ（レバー部４００）に挿通したネジＢ２を光源２０，３０に螺合することで、その螺合の中心線がＹ軸及び光軸Ｒ１，Ｒ２と交差する方向（直交する方向）に延びるため、ネジＢ２の締め付けを緩めることで、光源２０，３０をネジＢ２の中心線（軸線）周りで回転させることができるようになっている。すなわち、本実施形態に係る集魚灯１は、光源２０，３０を固定するためのネジＢ２が光源２０，３０の回転中心（回転軸）としても機能するようになっている。これにより、各光源２０，３０は、上述の如く、前記Ｙ軸及び光軸Ｒ１，Ｒ２と直交又は略直交する軸線周りで回転可能になっている。   In addition, by screwing the screw B2 inserted through the arm member 40a (lever part 400) into the light sources 20 and 30, the center line of the screwing intersects with the Y axis and the optical axes R1 and R2 (perpendicular direction). ), The light sources 20 and 30 can be rotated around the center line (axis) of the screw B2. That is, in the fish lamp 1 according to the present embodiment, the screw B2 for fixing the light sources 20 and 30 also functions as the rotation center (rotation axis) of the light sources 20 and 30. As a result, the light sources 20 and 30 can be rotated around an axis orthogonal to or substantially orthogonal to the Y axis and the optical axes R1 and R2, as described above.

本実施形態に係る集魚灯１は、上述の如く、光源２０，３０（光軸Ｒ１，Ｒ２）の角度θ１，θ２を調整できるように構成されているため、この角度調整を容易にすべく、光源２０，３０（光軸Ｒ１，Ｒ２）の角度θ１、θ２を確認するための角度測定手段５０が光源２０，３０毎に設けられている。かかる角度測定手段５０は、プレート状に形成されており、その所定位置を中心点として周囲に角度を示す目盛り（図示しない）が付されている。   As described above, the fish collection lamp 1 according to this embodiment is configured so that the angles θ1 and θ2 of the light sources 20 and 30 (optical axes R1 and R2) can be adjusted. An angle measuring means 50 for checking the angles θ1 and θ2 of the light sources 20 and 30 (optical axes R1 and R2) is provided for each of the light sources 20 and 30. The angle measuring means 50 is formed in a plate shape, and has a scale (not shown) indicating an angle around the predetermined position as a central point.

本実施形態に係る角度測定手段５０は、円板状に形成されており、その中心を基準にして周方向に角度を示す目盛りが付されている。かかる角度測定手段５０は、前記所定位置にネジＢ３を挿通するための貫通穴（図示しない）が穿設されており、その貫通穴をレバー部４００の貫通穴と同心にして該レバー部４００に固定されている。従って、本実施形態に係る集魚灯１は、角度測定手段５０及びレバー部４００の貫通穴に挿通したネジＢ２が光源本体２１，３１のネジ穴に螺合されている。   The angle measuring means 50 according to the present embodiment is formed in a disk shape, and a scale indicating an angle in the circumferential direction is given with reference to the center thereof. The angle measuring means 50 is provided with a through hole (not shown) through which the screw B3 is inserted at the predetermined position. The through hole is concentric with the through hole of the lever part 400. It is fixed. Therefore, in the fish lamp 1 according to the present embodiment, the screw B2 inserted through the through hole of the angle measuring means 50 and the lever part 400 is screwed into the screw hole of the light source bodies 21 and 31.

このように角度測定手段５０を設けるに当り、本実施形態に係る集魚灯１は、光源２０，３０（光源本体２１，３１）に角度測定手段５０の目盛りの何れか一つと一致する目印（図示しない）が設けられている。これにより、光源２０，３０の姿勢（角度）に対応するように、角度測定手段５０の目盛りの何れかと目印とが一致することになり、光源２０，３０の角度を把握できるようになっている。   In providing the angle measuring means 50 as described above, the fish collection lamp 1 according to the present embodiment is provided with a mark (illustrated) on the light sources 20 and 30 (light source main bodies 21 and 31) that matches one of the scales of the angle measuring means 50. Not). As a result, the mark coincides with any one of the scales of the angle measuring means 50 so as to correspond to the postures (angles) of the light sources 20 and 30, so that the angles of the light sources 20 and 30 can be grasped. .

そして、上記構成の集魚灯１は、光源２０，３０及び保持手段４０の重心位置が取付手段１０の重心位置（実際には、支持材Ｗに対する取り付け中心）を通る仮想的な直線上に位置するように設定されている。これにより、取付手段１０を支持材Ｗに取り付けた状態で光源２０，３０が適正な状態で垂設されるようになっている。   And the fish-lamp lamp 1 of the said structure is located on the virtual straight line through which the gravity center position of the light sources 20 and 30 and the holding means 40 passes the gravity center position (actually the attachment center with respect to the support material W) of the attachment means 10. Is set to As a result, the light sources 20 and 30 are suspended in an appropriate state with the attachment means 10 attached to the support member W.

本実施形態に係る集魚灯１は、以上の構成からなり、次に、該集魚灯１の取り付け態様及び作動について説明する。   The fish collection lamp 1 according to the present embodiment has the above-described configuration. Next, an installation mode and operation of the fish collection lamp 1 will be described.

上記構成の集魚灯１は、図１及び図５に示す如く、船舶Ｂの船体Ｂａ上に設けられた支持材Ｗに取り付けられる。ここで、船舶Ｂに対する取り付け態様を具体的に説明すると、船舶Ｂの船体Ｂａ上に支持材としてのワイヤーＷが船体の全長方向に架設されており、該ワイヤーＷの長手方向に間隔をあけて複数基の集魚灯１が取り付けられる。前記ワイヤーＷは、船舶Ｂの左舷側と右舷側とに架設されており、両ワイヤーＷのそれぞれに複数基の集魚灯１が取り付けられる。なお、図１に示す船舶Ｂは、操舵室Ｃが船体Ｂａの全長方向の略中央部に設けられており、前記ワイヤーＷは、操舵室Ｃの前方を視認するための窓よりもやや上方に位置するように架設されている。   The fish collection lamp 1 having the above configuration is attached to a support member W provided on the hull Ba of the ship B as shown in FIGS. Here, when the attachment mode with respect to the ship B is demonstrated concretely, the wire W as a support material is erected on the hull Ba of the ship B in the full length direction of the hull, and it leaves | separates in the longitudinal direction of this wire W. A plurality of fish collecting lights 1 are attached. The wires W are installed on the port side and the starboard side of the ship B, and a plurality of fish collecting lights 1 are attached to both the wires W, respectively. In the ship B shown in FIG. 1, the steering chamber C is provided at a substantially central portion in the full length direction of the hull Ba, and the wire W is slightly above the window for visually confirming the front of the steering chamber C. It is erected to be located.

そして、各ワイヤーＷに取り付けられる集魚灯１は、船体Ｂａの全長方向に延びる該船体Ｂａの中心線を基準にして対称となるように発光部２２，３２を外側に向けて取り付けられる。そして、各集魚灯１の光源２０，３０の角度θ１、θ２を調整し、図６に示す如く、それぞれの集魚灯１の２つの光源２０，３０の照射領域Ａ１，Ａ２が一列に並ぶように設定される。このとき、図６（ａ）に示す如く、各光源２０，３０の照射領域Ａ１，Ａ２の一部が重複した状態、或いは、図６（ｂ）に示す如く、照射領域Ａ１，Ａ２同士が接近した状態になるように光源２０，３０の角度θ１、θ２が調節される。すなわち、一列に並ぶ照射領域Ａ１，Ａ２間に集魚効率を低下させる暗部が形成されないように２つの光源２０，３０の姿勢が調節される。このとき、２つの光源２０，３０は、それぞれの照射領域Ａ１，Ａ２を完全に一致させないことを前提に、一方の光源２０は、Ｙ軸に対して光軸Ｒ１が４５°〜６５°に設定され、他方の光源３０は、Ｙ軸に対して光軸Ｒ２が５５°〜７５°に設定されることが好ましい。   Then, the fish lamp 1 attached to each wire W is attached with the light emitting portions 22 and 32 facing outward so as to be symmetrical with respect to the center line of the hull Ba extending in the full length direction of the hull Ba. Then, the angles θ1 and θ2 of the light sources 20 and 30 of each fishlight 1 are adjusted so that the irradiation areas A1 and A2 of the two light sources 20 and 30 of each fishlight 1 are aligned in a line as shown in FIG. Is set. At this time, as shown in FIG. 6A, the irradiation areas A1 and A2 of the light sources 20 and 30 partially overlap each other, or as shown in FIG. 6B, the irradiation areas A1 and A2 approach each other. The angles θ1 and θ2 of the light sources 20 and 30 are adjusted so as to achieve the above state. That is, the postures of the two light sources 20 and 30 are adjusted so that a dark part that reduces the fish collection efficiency is not formed between the irradiation areas A1 and A2 arranged in a line. At this time, on the premise that the two light sources 20 and 30 do not completely match the respective irradiation areas A1 and A2, the one light source 20 has the optical axis R1 set to 45 ° to 65 ° with respect to the Y axis. In the other light source 30, the optical axis R2 is preferably set to 55 ° to 75 ° with respect to the Y axis.

このように２つの光源２０，３０の照射領域Ａ１，Ａ２が一列に並ぶように設定された集魚灯１がワイヤーＷの長手方向に複数配設されることで、各集魚灯１の照射領域Ａ１，Ａ２が船体Ｂａの全長方向に連なる結果、船舶Ｂの周囲の略全域を照らすことができるようになる。   In this way, a plurality of fish collection lamps 1 set so that the irradiation areas A1 and A2 of the two light sources 20 and 30 are arranged in a line are arranged in the longitudinal direction of the wire W, so that the irradiation areas A1 of each fish collection lamp 1 are arranged. , A2 are continuous in the full length direction of the hull Ba, so that the entire area around the ship B can be illuminated.

以上のように、本実施形態に係る集魚灯１は、取付手段１０を支持材Ｗに取り付けた状態で上下方向となるＹ軸に対して交差する方向に光軸Ｒ１，Ｒ２が延びるように、２つの光源２０，３０が設けられているので、船舶Ｂ上に設けられた支持材Ｗに取付手段１０を取り付けた状態で、保持手段４０に保持された２つの光源２０，３０の光軸Ｒ１，Ｒ２が上下方向（Ｙ軸）と交差方向に延びた状態になり、各光源２０，３０で水面上を照らすことができる。このように、各光源２０，３０が水面のみを照らすことができるため、各光源２０，３０からの光が捕獲の対象を誘い込む領域以外に無駄に放射されることがなく、光源２０，３０に対して供給した電力を集魚のために有効に活用することができる。   As described above, the fish lamp 1 according to the present embodiment is such that the optical axes R1 and R2 extend in a direction intersecting the Y axis which is the vertical direction in a state where the attachment means 10 is attached to the support member W. Since the two light sources 20 and 30 are provided, the optical axes R1 of the two light sources 20 and 30 held by the holding means 40 in a state where the attachment means 10 is attached to the support member W provided on the ship B. , R2 extend in the direction perpendicular to the vertical direction (Y-axis), and the light sources 20 and 30 can illuminate the surface of the water. Thus, since each light source 20 and 30 can illuminate only the water surface, the light from each light source 20 and 30 is not radiated | emitted wastefully other than the area | region which invites the object of capture, and the light sources 20 and 30 are irradiated. On the other hand, the supplied power can be effectively used for collecting fish.

これにより、上記構成の集魚灯１は、光の照射を必要としない上空にまで光を放射（四方八方に光を放射）する従来の集魚灯よりも消費電力を抑えた上で良好な集魚効果を得ることができる。そして、上述の如く、消費電力が抑えられることで、各光源２０，３０に低電力（１０００Ｗ未満、好ましくは７５０Ｗ以下の低ワット）のものを採用して各光源２０，３０の発光時における発熱温度を低くすることができるため、比較的低価格な汎用の電球を光源２０，３０の発光部２２，３２として採用することができる。   Thereby, the fish collection lamp 1 having the above-described configuration has a better fish collection effect while suppressing power consumption than a conventional fish collection lamp that radiates light to the sky that does not require light irradiation (radiates light in all directions). Can be obtained. As described above, by suppressing power consumption, the light sources 20 and 30 are low power (less than 1000 W, preferably 750 W or less), and the light sources 20 and 30 generate heat during light emission. Since the temperature can be lowered, a general-purpose light bulb having a relatively low price can be used as the light emitting units 22 and 32 of the light sources 20 and 30.

また、各光源２０，３０は、互いの照射領域Ａ１，Ａ２が一列に並ぶように構成されているので、船舶Ｂが横揺れした場合（ローリングした場合）でも、船舶Ｂから所定の範囲（船舶Ｂから捕獲の対象を捕獲できる捕獲領域）に光を照射することができるため、船舶Ｂ周りに捕獲の対象を定常的に誘い込むことができる。   Moreover, since each light source 20 and 30 is comprised so that mutual irradiation area | region A1, A2 may be located in a line, even when the ship B rolls (when rolling), the predetermined range (ship) Since the light can be irradiated from B to the capture region where the capture target can be captured, the capture target can be steadily invited around the ship B.

また、各光源２０，３０は、前記Ｙ軸及び光軸Ｒ１，Ｒ２と直交又は略直交する軸線周りで回転可能に設けられているので、各光源２０，３０の光軸Ｒ１，Ｒ２の角度θ１、θ２を変更することができ、照射領域Ａ１，Ａ２を所望する位置に適宜変更することができる。また、角度測定手段５０が設けられているため、各光源２０，３０（光軸Ｒ１，Ｒ２）の角度を適正な角度に容易に設定することができる。   Further, since each of the light sources 20 and 30 is provided so as to be rotatable around an axis orthogonal or substantially orthogonal to the Y axis and the optical axes R1 and R2, the angle θ1 of the optical axes R1 and R2 of the light sources 20 and 30 is provided. , Θ2 can be changed, and the irradiation areas A1 and A2 can be appropriately changed to desired positions. Further, since the angle measuring means 50 is provided, the angles of the light sources 20, 30 (optical axes R1, R2) can be easily set to appropriate angles.

さらに、前記保持手段４０は、前記Ｙ軸と交差する方向に延びるレバー部４００を備え、該レバー部４００には、各光源２０，３０を保持する保持位置Ｐ１，Ｐ２が長手方向に間隔をあけて設定されているので、２つ以上の光源２０，３０を設けても、これらが真っ直ぐ下方に連なることがない。これにより、船舶Ｂの操舵室Ｃの前方に複数の集魚灯１が配設されても光源２０，３０等が操舵室Ｃからの視界から外れることになり、安全航行に貢献することができる。   Further, the holding means 40 includes a lever portion 400 extending in a direction intersecting the Y axis, and holding positions P1 and P2 for holding the light sources 20 and 30 are spaced apart in the longitudinal direction in the lever portion 400. Therefore, even if two or more light sources 20, 30 are provided, they do not continue straight down. Thereby, even if a plurality of fish-collecting lights 1 are disposed in front of the steering chamber C of the ship B, the light sources 20, 30 and the like are out of sight from the steering chamber C, which can contribute to safe navigation.

次に、本発明の第二実施形態について、添付図面を参照しつつ説明する。なお、本実施形態に係る集魚灯は、保持手段以外の構成が第一実施形態と同様であるので、以下の説明では、保持手段以外の構成については第一実施形態の各構成と同一名称及び同一符号を付して説明を割愛し、保持手段のみについて説明することとする。   Next, a second embodiment of the present invention will be described with reference to the accompanying drawings.

The lever portion 400 is configured to fix the light sources 20 and 30 to one end side on the attachment means 10 side and the other end side farther from the attachment means 10 than the one end side due to the height difference.

本実施形態に係る集魚灯１は、光源２０，３０が２つ設けられているため、各光源２０，３０を保持する保持位置Ｐ１，Ｐ２がレバー部４００の両端部に設定されている。各保持位置Ｐ１，Ｐ２には、光源２０，３０を保持するための前記ネジＢ２を挿通するための貫通穴（図示しない）が穿設されている。これにより、本実施形態に係る光源２０，３０は、レバー部４００の貫通穴に挿通したネジＢ２を光源本体２１，３１のネジ穴に螺合して締め付けることで保持位置Ｐ１，Ｐ２で保持（固定）されている。   Since the fish collection lamp 1 according to this embodiment is provided with two light sources 20 and 30, holding positions P <b> 1 and P <b> 2 for holding the light sources 20 and 30 are set at both ends of the lever portion 400. Each holding position P1, P2 has a through hole (not shown) through which the screw B2 for holding the light sources 20, 30 is inserted. Accordingly, the light sources 20 and 30 according to the present embodiment are held at the holding positions P1 and P2 by screwing and tightening the screws B2 inserted through the through holes of the lever portion 400 into the screw holes of the light source bodies 21 and 31 ( Fixed).

前記連結部４０１は、取付手段１０（補強部１００ｂ，１００ｂ）に固定される固定部４０１ａと、該固定部４０１ａから延出した連結部本体４０１ｂとで構成される。前記固定部４０１ａは、補強部１００ｂ，１００ｂのネジ穴（図示しない）の配置に対応するように複数の貫通孔（図示しない）が穿設されている。すなわち、固定部４０１ａは、ネジＢ１を挿通する貫通穴が穿設されており、該貫通穴に挿通したネジＢ１を補強部１００ｂ，１００ｂのネジ穴に螺合することで固定されるようになっている。   The connecting portion 401 includes a fixing portion 401a fixed to the attachment means 10 (reinforcing portions 100b and 100b) and a connecting portion main body 401b extending from the fixing portion 401a. The fixing portion 401a has a plurality of through holes (not shown) so as to correspond to the arrangement of screw holes (not shown) of the reinforcing portions 100b and 100b. That is, the fixing portion 401a has a through hole through which the screw B1 is inserted, and is fixed by screwing the screw B1 inserted through the through hole into the screw hole of the reinforcing portions 100b and 100b. ing.

前記固定部４０１ａ及び連結部本体４０１ｂは、何れも帯板状に形成されており、それぞれの長手方向の一端同士が接続されている。そして、本実施形態において、連結部本体４０１ｂは、固定部４０１ａに対してベース本体１００ａの他方の面側で斜め下方に向けて傾斜するように延びている。すなわち、固定部４０１ａ及び連結部本体４０１ｂは、所定角度（本実施形態においては鈍角）で屈曲形状をなしている。   Each of the fixing portion 401a and the connecting portion main body 401b is formed in a band plate shape, and one ends in the longitudinal direction thereof are connected to each other. And in this embodiment, the connection part main body 401b is extended so that it may incline toward diagonally downward on the other surface side of the base main body 100a with respect to the fixing | fixed part 401a. That is, the fixed portion 401a and the connecting portion main body 401b are bent at a predetermined angle (in this embodiment, an obtuse angle).

また、レバー部４００についても、帯板状に形成されており、他端部（他方の光源３０の保持位置Ｐ２が設定された他端部）が連結部本体４０１ｂの他端部に接続されている。該レバー部４００は、連結部本体４０１ｂの先下り方向（傾斜方向）とは反対向きに一端側（一方の光源２０の保持位置Ｐ１が設定された一端側）が先下りに傾斜している。これにより、連結部本体４０１ｂ及びレバー部４００は、所定角度（本実施形態においては略直角）で屈曲形状（Ｌ字状）をなしている。なお、本実施形態に係るアーム部材４０ａは、板材を打ち抜き加工して固定部４０１ａ、連結部本体４０１ｂ、及びレバー部４００が一体的に形成されている。   The lever portion 400 is also formed in a band plate shape, and the other end portion (the other end portion where the holding position P2 of the other light source 30 is set) is connected to the other end portion of the connecting portion main body 401b. Yes. The lever portion 400 has one end side (one end side where the holding position P <b> 1 of the one light source 20 is set) is inclined forward and backward in a direction opposite to the forward descending direction (inclination direction) of the connecting portion main body 401 b. As a result, the connecting portion main body 401b and the lever portion 400 are bent (L-shaped) at a predetermined angle (substantially at right angles in the present embodiment). In the arm member 40a according to the present embodiment, a fixing member 401a, a connecting part main body 401b, and a lever part 400 are integrally formed by punching a plate material.

これにより、本実施形態に係る保持手段４０のアーム部材４０ａは、連結部本体４０１ｂに接続されたレバー部４００の他端部が一端部よりも取付手段１０側に位置し、レバー部３００が一端側に向けて先下りに形成されている。そして、本実施形態においても、２つの光源２０，３０のうちの船体Ｂａ側を照射する一方の光源２０が取付手段１０から離間したレバー部４００の一端側の保持位置Ｐ１に固定され、一方の光源２０よりも遠方を照射する他方の光源３０が取付手段１０から離間したレバー部４００の他端側の保持位置Ｐ２に固定されている。   Thereby, in the arm member 40a of the holding means 40 according to the present embodiment, the other end portion of the lever portion 400 connected to the connecting portion main body 401b is located closer to the attachment means 10 than the one end portion, and the lever portion 300 is one end. It is formed forward and downward toward the side. And also in this embodiment, one light source 20 which irradiates the hull Ba side of the two light sources 20 and 30 is fixed to the holding position P1 on one end side of the lever portion 400 separated from the attachment means 10, and The other light source 30 that irradiates farther than the light source 20 is fixed to the holding position P <b> 2 on the other end side of the lever portion 400 that is separated from the mounting means 10.

以上のように、本実施形態に係る集魚灯１は、第一実施形態に対してアーム部材４０ａの形態が異なる点以外は、基本的な構成が共通しているので、第一実施形態の集魚灯１と同様の作用及び効果を奏することができる。   As described above, the fish collection lamp 1 according to the present embodiment has the same basic configuration except that the form of the arm member 40a is different from that of the first embodiment. The same operations and effects as the lamp 1 can be achieved.

すなわち、本実施形態に係る集魚灯１は、取付手段１０を支持材Ｗに取り付けた状態で上下方向となるＹ軸に対して交差する方向に光軸Ｒ１，Ｒ２が延びるように、２つの光源２０，３０が設けられているので、船舶Ｂ上に設けられた支持材Ｗに取付手段１０を取り付けた状態で、保持手段４０に保持された２つの光源２０，３０の光軸Ｒ１，Ｒ２が上下方向（Ｙ軸）と交差方向に延びた状態になり、各光源２０，３０で水面上を照らすことができる。このように、各光源２０，３０が水面のみを照らすことができるため、各光源２０，３０からの光が捕獲の対象を誘い込む領域以外に無駄に放射されることがなく、光源２０，３０に対して供給した電力を集魚のために有効に活用することができる。   That is, the fish lamp 1 according to the present embodiment has two light sources such that the optical axes R1 and R2 extend in the direction intersecting the Y axis which is the vertical direction with the attachment means 10 attached to the support member W. 20 and 30 are provided, the optical axes R1 and R2 of the two light sources 20 and 30 held by the holding means 40 in a state where the attaching means 10 is attached to the support material W provided on the ship B. The light source 20 and 30 can illuminate the surface of the water, extending in the vertical direction (Y axis) and the crossing direction. Thus, since each light source 20 and 30 can illuminate only the water surface, the light from each light source 20 and 30 is not radiated | emitted wastefully other than the area | region which invites the object of capture, and the light sources 20 and 30 are irradiated. On the other hand, the supplied power can be effectively used for collecting fish.

これにより、光の照射を必要としない上空にまで光を放射する従来の集魚灯よりも光源２０，３０の消費電力を抑えることができる。また、各光源２０，３０の照射領域が一列に並ぶように構成されているので、船舶Ｂが横揺れした場合（ローリングした場合）でも、船舶Ｂから所定の範囲（船舶Ｂから捕獲の対象を捕獲できる捕獲領域）に光を照射することができるため、船舶Ｂ周りに捕獲の対象を定常的に誘い込むことができる。   Thereby, the power consumption of the light sources 20 and 30 can be suppressed compared with the conventional fish collection light which radiates | emits light to the sky which does not require light irradiation. Further, since the irradiation areas of the light sources 20 and 30 are arranged in a line, even when the ship B rolls (rolls), a predetermined range from the ship B (the target of capture from the ship B) Since the light can be irradiated to the capture region that can be captured, the capture target can be steadily guided around the ship B.

また、各光源２０，３０は、前記Ｙ軸及び光軸Ｒ１，Ｒ２と直交又は略直交する軸線周りで回転可能に設けられているので、各光源２０，３０の光軸Ｒ１，Ｒ２の角度θ１、θ２を変更することができ、照射領域Ａ１，Ａ２を所望する位置に適宜変更することができる。   Further, since each of the light sources 20 and 30 is provided so as to be rotatable around an axis orthogonal or substantially orthogonal to the Y axis and the optical axes R1 and R2, the angle θ1 of the optical axes R1 and R2 of the light sources 20 and 30 is provided. , Θ2 can be changed, and the irradiation areas A1 and A2 can be appropriately changed to desired positions.

さらに、前記保持手段４０は、前記Ｙ軸と交差する方向に延びるレバー部４００を備え、該レバー部４００には、各光源２０，３０を保持する保持位置Ｐ１，Ｐ２が長手方向に間隔をあけて設定されているので、２つの光源２０，３０を設けても、これらが真っ直ぐ下方に連なることがない。これにより、船舶Ｂの操舵室Ｃの前方に複数の集魚灯１が配設されても光源２０，３０等が操舵室Ｃからの視界から外れることになり、安全航行に貢献することができる。   Further, the holding means 40 includes a lever portion 400 extending in a direction intersecting the Y axis, and holding positions P1 and P2 for holding the light sources 20 and 30 are spaced apart in the longitudinal direction in the lever portion 400. Therefore, even if the two light sources 20 and 30 are provided, they do not continue straight down. Thereby, even if a plurality of fish-collecting lights 1 are disposed in front of the steering chamber C of the ship B, the light sources 20, 30 and the like are out of sight from the steering chamber C, which can contribute to safe navigation.

発明者は、従来の集魚灯の性能と本発明に係る集魚灯の一例として第一実施形態の集魚灯（２つの光源２０，３０を一列に配置した集魚灯）の性能とを確認すべく、照度分布の解析を行った。解析の対象は、従来の集魚灯を６０基、すなわち電球を６０灯（左舷に３０灯、右舷に３０灯）設けた船舶Ｂと、本発明の集魚灯を７０基（左舷に３５基、右舷側に３５）設けた船舶Ｂとした。そして、横並びに配置される集魚灯１の全ての条件を同一に設定するようにした。すなわち、各集魚灯１の取り付け高さは、水面を基準に概ね４ｍに設定することとし、隣り合う集魚灯１の一方の光源２０の角度θ１が同一角度となり、また、他方の光源３０，３０の角度θ２が同一角度になるよう、各集魚灯１の各光源２０，３０の角度θ１，θ２を適宜変更するようにした。なお、以下において、船体Ｂａ側を照射する一方の光源２０を第一光源といい、第一光源２０よりも遠方を照射する他方の光源３０を第二光源ということとする。   The inventor is to confirm the performance of the conventional fish collection lamp and the performance of the fish collection lamp of the first embodiment (fish collection lamp in which two light sources 20 and 30 are arranged in a row) as an example of the fish collection lamp according to the present invention. The illuminance distribution was analyzed. The objects of analysis are the ship B with 60 conventional fishlights, that is, 60 light bulbs (30 lights on the port and 30 lights on the starboard), and 70 fishlights of the present invention (35 on the port, starboard) It was set as the ship B provided on the side 35). And all the conditions of the fishlight 1 arrange | positioned side by side were set identically. That is, the mounting height of each fishlight 1 is set to approximately 4 m with respect to the water surface, the angle θ1 of one light source 20 of the adjacent fishlight 1 is the same angle, and the other light sources 30, 30 The angles θ1 and θ2 of the light sources 20 and 30 of the fish collection lamps 1 are appropriately changed so that the angles θ2 of the fishfishes 1 are the same. In the following, one light source 20 that irradiates the hull Ba side is referred to as a first light source, and the other light source 30 that irradiates far from the first light source 20 is referred to as a second light source.

上記の条件を前提に解析を行ったところ、図９〜図１９に示すような結果が得られた。なお、図９〜図１９において、二点鎖線で包囲した領域Ａ’が船舶Ｂ上から捕獲の対象（魚やイカ、エビ等）を捕獲できる捕獲領域である。   When analysis was performed on the assumption of the above conditions, results as shown in FIGS. 9 to 19 were obtained. 9 to 19, a region A ′ surrounded by a two-dot chain line is a capture region where a capture target (fish, squid, shrimp, etc.) can be captured from the ship B.

ここで解析結果について具体的に説明すると、従来の船舶Ｂ（従来の電球で構成される集魚灯１）は、３ｋｗの電球を６０灯設けた場合（合計１８０ｋｗ：図９参照）、２．７ｋｗの電球を６０灯設けた場合（合計１６２ｋｗ：図１０参照）、２ｋｗの電球を６０灯設けた場合（合計１２０ｋｗ：図１１参照）において、捕獲領域Ａ’で合計電力に比例して照度が高くなることが確認できた。すなわち、捕獲領域Ａ’において、図９に示す如く、３ｋｗの電球を６０灯設けた場合（合計１８０ｋｗ）に、左舷側及び右舷側の捕獲領域Ａ’で最大１４０００ルクス、図１０に示す如く、２．７ｋｗの電球を６０灯設けた場合（合計１６２ｋｗ）に、左舷側及び右舷側の捕獲領域Ａ’で最大１２０００ルクス、図１１に示す如く、２ｋｗの電球を６０灯設けた場合（合計１２０ｋｗ）に、左舷側及び右舷側の捕獲領域Ａ’で最大８０００ルクスであった。   Here, the analysis results will be described in detail. In the case of a conventional ship B (fishing lamp 1 composed of conventional light bulbs), 60 light bulbs of 3 kW are provided (total 180 kW: see FIG. 9), 2.7 kW When 60 light bulbs are provided (total 162 kw: see FIG. 10), when 60 light bulbs of 2 kw are provided (total 120 kw: see FIG. 11), the illuminance is high in proportion to the total power in the capture region A ′. It was confirmed that That is, in the capture area A ′, as shown in FIG. 9, when 60 bulbs of 3 kW are provided (total 180 kW), the capture area A ′ on the port side and starboard side has a maximum of 14,000 lux, as shown in FIG. When 60 light bulbs of 2.7 kW are provided (total 162 kw), a maximum of 12000 lux is obtained in the capture area A ′ on the port side and starboard side. As shown in FIG. 11, 60 light bulbs of 2 kW are provided (total 120 kw) ), The maximum was 8000 lux in the capture area A ′ on the port side and starboard side.

これに対し、本発明に係る船舶Ｂ（集魚灯１）は、低電力でありながら捕獲領域Ａ’で従来の電球を設けた場合と同等或いはそれ以上の照度が得られ、また、捕獲領域Ａ’での照度が均一であることが判る。   On the other hand, the ship B (fishing lamp 1) according to the present invention has an illuminance equivalent to or higher than that in the case where a conventional light bulb is provided in the capture area A ′ while having low power. It can be seen that the illuminance at 'is uniform.

具体的には、図１２に示す如く、各集魚灯１の２つの光源２０，３０のうち船体Ｂａ側を照射する第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１（斜め下方に傾斜させた光軸Ｒ１のＹ軸に対する小さい方（内角）の角度）を４５°とし、第二光源３０を７００ＷでＹ軸に対する光軸Ｒ２の角度θ２（斜め下方に傾斜させた光軸Ｒ２のＹ軸に対する小さい方（内角）の角度）を６５°とした場合（合計７７ｋｗ）、左舷側及び右舷側の捕獲領域Ａ’で最大１４０００ルクスもの照度が得られている。   Specifically, as shown in FIG. 12, the first light source 20 that irradiates the hull Ba side of the two light sources 20 and 30 of each fishlight 1 is 400 W at an angle θ1 of the optical axis R1 with respect to the Y axis (inclined downward). The smaller one (inner angle) of the inclined optical axis R1 with respect to the Y axis is 45 °, and the second light source 30 is 700 W at an angle θ2 of the optical axis R2 with respect to the Y axis (of the optical axis R2 inclined obliquely downward). When the smaller one (inner angle) with respect to the Y-axis is 65 ° (total 77 kW), an illuminance of up to 14,000 lux is obtained in the port-side and starboard-side capture areas A ′.

また、図１３に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を４５°とし、第二光源３０を７００ＷでＹ軸に対する光軸Ｒ２の角度θ２を５５°とした場合（合計７７ｋｗとした場合）、左舷側及び右舷側の捕獲領域Ａ’で最大１６０００ルクスもの照度が得られている。   As shown in FIG. 13, the first light source 20 is 400 W, the angle θ1 of the optical axis R1 with respect to the Y axis is 45 °, the second light source 30 is 700 W, and the angle θ2 of the optical axis R2 with respect to the Y axis is 55 °. In this case (when the total is 77 kW), an illuminance of up to 16000 lux is obtained in the capture area A ′ on the port side and starboard side.

さらに、図１４に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を４５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を４５°とした場合（合計５６ｋｗ）や、図１５に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を５５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を５５°とした場合（合計５６ｋｗ）、左舷側及び右舷側の捕獲領域Ａ’で最大１６０００ルクスの照度が得られている。   Further, as shown in FIG. 14, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 45 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis is 45 °. In the case (total 56 kw), as shown in FIG. 15, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 55 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis. Is 55 ° (total 56 kw), the maximum illuminance of 16000 lux is obtained in the capture area A ′ on the port side and starboard side.

そして、図１６に示す場合、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を５５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を６５°とした場合（合計５６ｋｗ）や、図１７に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を６５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を６５°とした場合（合計５６ｋｗ）、遠方側での光の照射が増すため、左舷側及び右舷側の捕獲領域Ａ’で最大８０００〜１００００ルクスになるが、照度分布の均一性が崩れる傾向あることが判る。   In the case shown in FIG. 16, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 55 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis is 65 °. In the case (total 56 kw), as shown in FIG. 17, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 65 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis. When the angle is set to 65 ° (total 56 kw), the light irradiation on the far side increases, so the maximum is 8000 to 10000 lux in the port-side and starboard-side capture areas A ′, but the uniformity of the illuminance distribution tends to collapse I know that there is.

これに対し、図１８に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を４５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を５５°とした場合（合計５６ｋｗ）、左舷側及び右舷側の捕獲領域Ａ’で最大１６０００ルクスもの照度が得られている。また、図１９に示す如く、第一光源２０を４００ＷでＹ軸に対する光軸Ｒ１の角度θ１を４５°とし、第二光源３０を４００ＷでＹ軸に対する光軸Ｒ２の角度θ２を６５°とした場合（合計５６ｋｗ）、左舷側及び右舷側の捕獲領域Ａ’で最大１２０００ルクスの照度が得られている。   On the other hand, as shown in FIG. 18, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 45 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis is 55 °. (Total 56 kw), an illuminance of up to 16000 lux is obtained in the capture area A ′ on the port side and starboard side. 19, the first light source 20 is 400 W and the angle θ1 of the optical axis R1 with respect to the Y axis is 45 °, and the second light source 30 is 400 W and the angle θ2 of the optical axis R2 with respect to the Y axis is 65 °. In the case (56 kw in total), an illuminance of up to 12000 lux is obtained in the capture area A ′ on the port side and starboard side.

このように、本発明に係る集魚灯１は、低電力でありながらも捕獲領域Ａ’で十分な照度が得られる。また、第二光源３０が第一光源２０よりも遠方を照射するため、仮に船体Ｂａが横揺れした場合であっても船体Ｂａ近傍の捕獲領域Ａ’に十分な照度が得られることが判る。特に、第一光源２０の角度θ１よりも第二光源３０の角度θ２を大きくすることで、一列に並ぶ照射領域Ａ１，Ａ２が一体になって船体Ｂａ近傍から遠方に向けて延びた領域となるため、捕獲領域Ａ’を含んでその遠方にまで十分な照度が得られ、船体Ｂａに横揺れに影響を受けにくくして集魚効率を高めることができる。なお、上記解析結果は、各集魚灯１の取り付け高さを概ね４ｍに設定した場合であるが、集魚灯１の取り付け高さを約３．５ｍ〜４．５ｍの範囲で変更しても上記解析結果と同様の結果になることを確認している。   As described above, the fish lamp 1 according to the present invention can obtain a sufficient illuminance in the capture region A ′ while having low power. Moreover, since the 2nd light source 30 irradiates far away from the 1st light source 20, even if it is a case where the hull Ba rolls, it turns out that sufficient illumination intensity is obtained in the capture area | region A 'near hull Ba. In particular, by making the angle θ2 of the second light source 30 larger than the angle θ1 of the first light source 20, the irradiation areas A1 and A2 arranged in a row are integrated into an area extending from the vicinity of the hull Ba toward the far side. Therefore, sufficient illuminance can be obtained far beyond the capture area A ′, and the hull Ba is less susceptible to rolling, and the fish collection efficiency can be increased. In addition, although the said analysis result is a case where the attachment height of each fishlight 1 is set to about 4 m, even if it changes the attachment height of the fishlight 1 in the range of about 3.5 m-4.5 m, It has been confirmed that the results are similar to the analysis results.

尚、本発明の集魚灯及び該集魚灯を備えた船舶は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   Note that the fishlight of the present invention and the ship equipped with the fishlight are not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention.

上記各実施形態において、各光源２０，３０の照射領域Ａ１，Ａ２が一列に並ぶ、すなわち、一方の光源２０が船舶Ｂ側を照射する一方で、他方の光源３０が一方の光源２０よりも遠方を照射するように光源２０，３０を設けたが、例えば、図２０に示す如く、２つ以上の光源２０，３０は、互いの照射領域Ａ１，Ａ２が略一致するように設けられてもよい。このとき、２つの光源２０，３０は、それぞれの照射領域Ａ１，Ａ２を一致さることを前提に、それぞれの光軸Ｒ１がＹ軸に対して４５°〜６５°に設定されることが好ましい。   In each said embodiment, irradiation area | region A1, A2 of each light source 20 and 30 is located in a line, ie, one light source 20 irradiates the ship B side, while the other light source 30 is farther than one light source 20 However, for example, as shown in FIG. 20, two or more light sources 20 and 30 may be provided so that their irradiation areas A1 and A2 substantially coincide with each other. . At this time, it is preferable that the two light sources 20 and 30 have their respective optical axes R1 set to 45 ° to 65 ° with respect to the Y axis on the assumption that the irradiation areas A1 and A2 coincide with each other.

このようにすれば、２つ以上の光源２０，３０のそれぞれの光が同一領域Ａ１，Ａ２に照射されることになるため、船舶Ｂがローリングした場合に、照射領域Ａ１，Ａ２が移動して船舶Ｂ近傍の捕獲領域に安定して光を照射できなくなるが、各光源２０，３０からの光が重なる分、その領域内での照度が増すことになる。従って、船舶Ｂの横揺れ等が少ないときに、捕獲領域を高照度で照らすことができ、集魚効果をよりいっそう高めることができる。この場合、各光源２０，３０の光源の角度を変更することで、互いの照射領域Ａ１，Ａ２を一致させることができるため、集魚灯１の構成としては、上記各実施形態に係るものと同一のものを採用することができる。   If it does in this way, since each light of two or more light sources 20 and 30 will be irradiated to the same field A1, A2, when ship B rolls, irradiation field A1, A2 will move. Although it becomes impossible to irradiate light stably to the capture region in the vicinity of the ship B, the illuminance in the region increases as the light from the light sources 20 and 30 overlaps. Therefore, when there is little rolling of the ship B etc., a capture area | region can be illuminated with high illumination intensity and the fish collection effect can be improved further. In this case, since the irradiation areas A1 and A2 can be matched by changing the angle of the light source of each of the light sources 20 and 30, the configuration of the fish collecting lamp 1 is the same as that according to each of the above embodiments. Can be adopted.

そして、上記各実施形態において、光源２０，３０を回転可能に設け、光源２０，３０の光軸Ｒ１，Ｒ２の角度を変更できるようにしたが、これに限定されるものではなく、例えば、各光源２０，３０の照射領域Ａ１，Ａ２が一列に並んで連続する又は一部が重複するように光源２０，３０の姿勢を設定して固定するようにしてもよい。また、上述の如く、各光源２０，３０の照射領域Ａ１，Ａ２を一致させる場合も、照射領域Ａ１，Ａ２が重なるように光源２０，３０の姿勢を設定して固定するようにしてもよい。   In each of the above embodiments, the light sources 20 and 30 are provided so as to be rotatable, and the angles of the optical axes R1 and R2 of the light sources 20 and 30 can be changed. The postures of the light sources 20 and 30 may be set and fixed so that the irradiation areas A1 and A2 of the light sources 20 and 30 are arranged in a row and are continuous or partially overlapped. Further, as described above, when the irradiation areas A1 and A2 of the light sources 20 and 30 are matched, the postures of the light sources 20 and 30 may be set and fixed so that the irradiation areas A1 and A2 overlap.

また、各光源２０，３０は、それぞれの照射領域Ａ１，Ａ２が一列に並ぶように設けられたり、それぞれの照射領域Ａ１，Ａ２が一致するように設けられたりしたものに限定されるものではなく、取付手段１０が支持材Ｗに取り付けられた状態で上下方向となる一方向に真っ直ぐに延びる仮想軸（Ｙ軸）に対して交差する方向に光軸Ｒ１，Ｒ２が延びるように設けられ、船舶Ｂの支持材Ｗに取り付けられた状態で、同時に水面（捕獲領域）に向けて照射できればよい。   Further, the light sources 20 and 30 are not limited to those in which the respective irradiation areas A1 and A2 are provided so as to be arranged in a line, or provided so that the respective irradiation areas A1 and A2 are aligned. The optical means R1 and R2 extend in a direction intersecting with a virtual axis (Y axis) extending straight in one direction which is the vertical direction in a state where the attachment means 10 is attached to the support member W. What is necessary is just to be able to irradiate toward the water surface (capture region) at the same time in a state of being attached to the support material W of B.

上記各実施形態において、光源２０，３０を２つ設けたが、これに限定されるものではなく、例えば、光源２０，３０を３つ以上設けるようにしてもよい。この場合においても、各光源２０，３０は、光軸Ｒ１，Ｒ２がＹ軸と交差する方向に延びるよう設けられることは勿論のことである。   In each said embodiment, although two light sources 20 and 30 were provided, it is not limited to this, For example, you may make it provide three or more light sources 20, 30. FIG. Also in this case, it goes without saying that the light sources 20 and 30 are provided so that the optical axes R1 and R2 extend in a direction intersecting the Y axis.

上記各実施得形態において、光源２０，３０としてバルブの半分の領域に反射膜（反射鏡）が設けられた電球を採用したが、これに限定されるものではなく、発光部２２，３２の発光に伴う光の指向性を付与するための反射傘（反射構造）を電球とは別に設けた投光器型のもの、すなわち、投光器型集魚灯であってもよい。但し、投光器型のものを採用すると、反射構造の存在で風の影響を受けたり、反射構造が水分や塩分によって反射効率を低下させるようなダメージを受けたりする虞があり、また、このようなダメージを防止するのに前面ガラスを設けると大型化したり重くなったりするため、上記各実施形態のように、光源２０，３０（発光部２２，３２）には、バルブ内面に反射膜（反射鏡）が設けられた軽量で且つコンパクトな電球を採用することが好ましい。   In each of the above embodiments, the light source 20 and 30 is a light bulb provided with a reflecting film (reflecting mirror) in a half region of the bulb. However, the present invention is not limited to this, and the light emitting units 22 and 32 emit light. The projector type thing which provided the reflecting umbrella (reflective structure) for providing the directivity of the light accompanying to separately from a light bulb, ie, a projector type fish lamp, may be used. However, if a projector type is used, there is a risk of being affected by the wind due to the presence of the reflecting structure, or the reflecting structure may be damaged by moisture or salt to reduce the reflection efficiency. If a front glass is provided to prevent damage, the size of the light source increases and becomes heavy. Therefore, as in each of the above embodiments, the light sources 20 and 30 (light emitting units 22 and 32) have a reflecting film (reflecting mirror) on the inner surface of the bulb. It is preferable to employ a light bulb that is light and compact.

また、上記各実施形態において、光源本体２１，３１の他端部を拡大させ、バルブ２２，３３の一部（基端側）を光源本体２１，３１の他端部に収容するようにしたが、これに限定されるものではなく、例えば、バルブ２２，３３の略全体が露出するようにしてもよい。   In each of the above embodiments, the other end portions of the light source bodies 21 and 31 are enlarged, and a part (base end side) of the bulbs 22 and 33 is accommodated in the other end portions of the light source bodies 21 and 31.

However, the present invention is not limited to this. The light sources 20 and 30 may be fixed to the holding means 40 after the angles of the axes R1 and R2 are set to predetermined angles.

You may make it pinch | interpose the wire W with the one piece member 101,102. Moreover, the attachment means 10 is not limited to what was comprised with the base 100 and the piece members 101 and 102, For example, you may make it comprise the attachment means 10 with a clamp. And although the wire W was employ | adopted as the support material W arrange | positioned on the hull Ba, it is not limited to this, For example, a rod body is arrange | positioned so that it may extend in a horizontal direction and this may be used as the support material W. Alternatively, a plurality of rods extending in the vertical direction may be arranged corresponding to the arrangement of the fish collection lamps 1. That is, the attachment means 10 may be appropriately changed according to the mode of the support material W provided on the hull Ba as required.

上記各実施形態において、保持手段４０を一対設けて光源２０，３０を両側から保持するようにしたが、これに限定されるものではなく、例えば、一つの保持手段４０で複数の光源２０，３０を保持するようにしても勿論よい。   In each of the above embodiments, a pair of holding means 40 is provided to hold the light sources 20 and 30 from both sides. However, the present invention is not limited to this. For example, a plurality of light sources 20 and 30 are formed by one holding means 40. Of course, it may be made to hold.

上記各実施形態において、レバー部４００の貫通穴に挿通したネジＢ２を光源２０，３０のネジ穴に挿通することで各光源２０，３０を保持するようにしたが、これに限定されるものではなく、例えば、アーム部材４０ａ（レバー部４００）に凸部を設けるとともに、光源２０，３０（光源本体２１，３１）に凸部を嵌合させる凹部を形成し、この凸部と凹部との嵌合によって光源２０，３０を保持するようにしても勿論よい。   In each of the above embodiments, the light sources 20 and 30 are held by inserting the screws B2 inserted through the through holes of the lever portion 400 into the screw holes of the light sources 20 and 30, but the present invention is not limited to this.
