Description

  The present invention relates to a fish collection technique using a fish collection lamp having an electrodeless discharge lamp, and an illumination technique using the fish collection lamp, and in particular, using a fish collection lamp having an electrodeless discharge lamp, The present invention relates to a fish collection technique for catching a large amount of fish or the like, or a general outdoor lighting device using this fish collection light.

  Traditionally, some cephalopods and fish, such as squid, saury, horse mackerel, mackerel, and sardine, have the property of collecting light, and light is emitted toward the sea surface from the light source in the fishing light provided on the fishing boat. However, a technique for catching a large amount of the cephalopods and fish collected in the light irradiated on the sea surface and the light transmitted in the sea is known. The above cephalopods and fish have been considered to have a greater fish collection effect when the light emitted to the sea surface and the sea is brighter. For this reason, a large amount of light sources have been provided on fishing boats, and light sources with low power and high light intensity have been developed. The lighting device used for fish collection is called a fish collection lamp (or fish collection device). The light source has been used as a torch since ancient times, and it has been improved with the changing times, oil lamps, incandescent lamps, halogen lamp lamps, etc. In recent years, metal halide lamps have been mainly used.

  However, a metal halide lamp is disclosed in, for example, Patent Document 1 below, “Currently, the cost of a generator for lighting a fishing light of a fishing boat that carries out squid fishing fishery accounts for 60% or more of the total cost of operation. Including light replacement costs, it accounts for more than 40% of the total operating cost, and in recent years, the high crude oil has caused a significant hindrance to fishery management. Metal halide lamps are mostly used, however, metal halide lamps usually require very large power consumption of about 1 kW to 3 kW, so that power consumption is high and the temperature of the glass surface during light emission is very high. There is a risk of fire, burns, etc., and there is a disadvantage that the service life is as short as about 3,000 hours. When used on the moon, the fish collection performance must be reduced and replaced, and a ballast that is heavy and has a large volume is required. Occupancy reduces the volume of the fish hold where fish are stored, and the light from the metal halide lamp is radiated in all directions through the glass bulb, so that the sky and deck are not only necessary for collecting fish. In addition, 60 to 70% or more of the total amount of light is wasted, and the light emitted from the metal halide lamp is generated from the infrared region to a part of the ultraviolet region, so that the fish to be collected such as squid Light other than light in a wavelength band effective for fish collection was also emitted, and the use of light for general fish collection was inefficient ”(see paragraphs“ 0003 ”to“ 0005 ”). Has been There has been a problem UNA. In order to solve such a problem, a new light source has been used. Typical examples of the new light source include a light emitting diode (hereinafter referred to as “LED”) and an electrodeless discharge lamp (also referred to as “electromagnetic induction lamp”).

  For example, the following Patent Documents 1 to 3 relate to fish collecting lamps using LEDs as light sources, and the following Patent Document 4 relates to fish collecting lights using electrodeless discharge lamps as light sources.

  Unlike metal halide lamps that irradiate light in all directions, LEDs have directivity, so by concentrating the irradiation light from the light source in a bundle, it is possible to effectively irradiate a specific area with less power. it can. Moreover, the transmittance of the irradiation light into the sea is better than that of a metal halide lamp. As a fish collection lamp using an LED as a light source, for example, in Patent Document 2 below, “a plurality of blue light emitting diodes emitting blue light in a wavelength region of 400 nm to 500 nm are arranged in a matrix on a substrate, A planar light source, and using the LED planar light source, a right side light source that illuminates the right side of the ship and a left side light source that illuminates the left side of the ship, A working planar light source is arranged between the left planar light source, and light emitting diodes for irradiating white light for illuminating the deck are arranged in a matrix on the substrate, and the right planar light source and The left planar light source and the working planar light source are provided to form a planar light source unit, and a plurality of the planar light source units are arranged side by side above a substantially center line of a ship deck. To collect light ”(see“ Claim 1 ”) ).

  In addition, the electrodeless discharge lamp irradiates light in all directions, similar to the metal halide lamp, but unlike the metal halide lamp, it generates less heat, so it is housed in a housing provided with a reflector, and the LED. Similarly, light can be effectively applied to a specific region. For example, the following Patent Document 4 states that “a light collecting device that emits light from a light source attached to a squid fishing fishing boat, and the light source includes purple, blue, green, yellow, orange, A light source that emits light that includes all wavelengths of red, and in particular has a high energy ratio of violet, green, and orange wavelengths, and the holder that holds the light source stands upright in a squid fishing device provided in a boat. A fish collection provided with an angle adjustment mechanism that can be tilted and can be rotated in the standing and tilting direction of the cradle with respect to the center part of the cradle that protrudes toward the sea when tilting, and that adjusts the rotation angle of the holder "Lamp device" (refer to "Claim 1"), "The light source is composed of an electrodeless discharge lamp" (Refer to "Claim 2"), "Fig. 4 shows the fishlight lamp device 14 provided above. The fish lamp device 14 shows the light source 41 in the stable state. 43, and disposed above the squid fishing device 13. The light source 41 is provided on one side by a reflective cover member 44 as a holding body so as to irradiate light in all directions in one direction. The side is covered ”(see paragraph“ 0034 ”, FIG. 4),“ Of the light emitted from the light source 41, the light on the reflective cover member 44 side is reflected by the reflective cover member 44, and the posture of the reflective cover member 44 is Since the reflective cover member 44 is directed obliquely downward as described above, the light 61 is irradiated to the outside of the ship and enters the sea ”(see paragraph“ 0054 ”, FIG. 10). .).

  Further, Patent Document 4 describes the invention described in Patent Document 2 using an LED, “With these circumstances, a light-emitting diode that consumes less power, does not require a ballast, and does not include ultraviolet rays in the light to be irradiated. (LED: Light Emitting Diode) has been proposed.The light collecting device using a light emitting diode compensates for the disadvantage that the light amount is small and it is difficult to reach light far away. Blue light-emitting diodes that emit blue light are used, based on the idea that blue light with a wavelength of about 470 nm would have the effect of collecting fish because it matches the squid's visibility wavelength. The effects on fishing results have not been demonstrated yet, partly because of the low light intensity in water. In addition, it may be caused by poor color rendering, that is, in addition to the fact that light is emitted in the sea, even if only blue light is applied, the color is not visible. It is imagined that this is unnatural ”(see paragraphs“ 0008 ”and“ 0009 ”).

Japanese Patent No. 5510549 Japanese Patent No. 3597498 Registered Utility Model No. 3096561 JP 2012-125202 A

  In the inventions described in Patent Documents 1 and 3, a single fish collection lamp is configured using a plurality of LEDs as light sources, and at least two rows of fish collection lamps along the left and right cages are provided on the left and right side of the fishing boat in order to enhance the fish collection effect. A row is arranged (see FIG. 6 of Patent Document 1 and FIG. 1 of Patent Document 3). The port side fish collection lamp train is configured to irradiate light to the sea surface and the sea in the port direction, and the starboard side fish collection lamp train is configured to irradiate light to the sea surface and the sea in the starboard direction. Further, in the invention described in Patent Document 4, two rows of fish are collected along the left and right side of the fishing boat on the left and right side of the fishing boat in order to configure one fish collection light using a plurality of electrodeless discharge lamps as light sources and enhance the fish collection effect. A light train is disposed (see FIG. 1 of Patent Document 4). In this way, a configuration in which at least two rows of fish collecting light trains are arranged on the left and right side of the fishing boat increases the total weight of the fishing boat, so that the fuel consumption of the fishing boat is deteriorated. In addition, it is easily affected by wind and waves, and the fishing boat balance becomes unstable. On the other hand, the above-mentioned Patent Document 2 uses an “LED planar light source”, and “a support rod b is horizontally placed by a support p standing up and down above a substantially center line on a deck d of a fish boat S. 2, the planar light source unit 1 can be attached to the support bar b with the hook 36 and the fixing screw 37 ”(see paragraph“ 0014 ”, FIGS. 2 and 3). ), And a plurality of “planar light source units 1” as fish collection lamps are arranged in a line on the longitudinal center line of the fishing boat. May be improved, but in order to make the radiation light efficiently incident on the sea surface in the horizontal direction of the ship and in the sea, the light source for fish collection is “the left side surface that illuminates the sea side on the left side of the ship. ”Light source” and “Right light source that illuminates the right side of the ship”, 2 To require a light source. In the first place, the LED has an adverse effect on visibility and workability for an operator who has a lot of glare and works on the deck of a fishing boat. For this reason, in the invention described in Patent Document 2, Aside from the “right-side light source and left-side light source”, a “planar light source for work in which light-emitting diodes that illuminate white light for illuminating the deck are arranged in a matrix on the substrate” is provided. It is guessed.

  Note that the electrodeless discharge lamp, unlike the LED described above, has omnidirectionality (also referred to as “omnidirectional”), can irradiate light at a wide angle, is bright in all directions, and has a measured illuminance. Can shine brighter than. For this reason, the space where light and light overlap is large, and it is difficult to shadow luggage and equipment, so it is easy to work on the deck of a fishing boat. Moreover, since there is little glare, an operator's visibility and workability are not adversely affected.

  In the invention described in Patent Document 4, an electrodeless discharge lamp is used as a fish lamp device for squid fishing, but an “electrodeless discharge lamp” is used as the “light source 41” of the “fish collector 14”. Although it is used, the light source 41 is configured so that one side is covered with a reflective cover member 44 as a holding body in order to irradiate light emitted in all directions in one direction. For this reason, since it is necessary to arrange the “fish collection lamp device 14” in two rows along the fishing boat's left and right ridges (see FIGS. 1 and 2), as described above, the fuel consumption deteriorates due to the weight increase and the balance is not balanced. It is assumed that there are problems such as stability. As can be seen from FIG. 2, the “fish collection lamp device 14” cannot illuminate the deck of the “squid fishing fishing boat 11”, and if considering the safety and efficiency of the work, It is necessary to provide another lighting device, and there is a possibility that problems such as fuel consumption and balance stability of the fishing boat are deteriorated.

  Next, let us mention the mechanism of the fishing light for squid. As described in paragraph “0002”, some cephalopods such as squid have been conventionally considered to have the property of gathering in light (positive phototaxis). For this reason, it is said that the brighter the light source, the greater the fish collection effect, and a large amount of light source (fish collection light) is provided on the fishing boat, or a light source with low power and high light intensity has been developed.

  However, in recent years, plankton and small fish with positive phototaxis are attracted and gathered by the light irradiated on the sea surface and in the sea, and squids shadow the bottom of the ship to supplement the collected plankton and small fish. Plankton that gathers in the dark part of the non-irradiated area of the squid, or that the squid that has floated near the sea surface due to vertical movement gathers in the irradiated area because the squid has negative phototacticity (a property to escape from light) It is thought that it gathers in the dark part of the non-irradiated area such as the shadow of the ship bottom to supplement the fish and small fish.

  Thus, it is considered that the squid gathers not in the light irradiation region (bright region) but in the light non-irradiation region (dark region) like a shadow portion of the ship bottom. Regarding this, Patent Document 1 describes that “squid is approaching with light of any wavelength, but when it receives a strong stimulus, it escapes and searches for shadows” (see paragraph “0069”). According to Patent Document 2, “The squid is usually on the sea floor of about 100m to 200m, but it is attracted by the light from the fishing light 1 and floats up to about 50m. It is described as “Hiding the body, jumping quickly to the fish etc. swarming under the irradiation light of the fish lamp A” and trying to prey on the legs ”(see paragraph“ 0020 ”). “When the sea surface WP and the underwater WI near the fishing boat 1 are irradiated with LED light of blue, green or transparent, nearby fish (for example, squid) are invited to the light and approach the fishing boat 1 in the shadow. Gather in the fish collection area BA. Since it has the habit of coming, it gathers in the shaded fish collection area BA "(see paragraph" 0042 "). Patent Document 4 states that" the shadow of the hull 12 formed below the hull 12 as described above. 62 is relatively clear in the boundary with the bright part, so that the place where the squid gathers can be easily determined, that is, the range of collecting the squid can be limited ”(see paragraph“ 0060 ”).

  Based on the above, in squid fishing using a fish-collecting lamp, the irradiated area where plankton and small fish gather (bright area) and the non-irradiated area where squid gathers to prey on the collected plankton and small fish (dark area) It is considered to be a problem to form so that the fish collection effect / fishing effect is greatly improved.

  Therefore, the present invention first uses an electrodeless discharge lamp instead of a directional LED as a light source for a fish collection lamp, and a reflection plate that reflects the direct light emitted by the electrodeless discharge lamp is provided in the fish collection lamp. The purpose is to provide a fishing light that can irradiate a wide range in the port direction, starboard direction, and deck direction of a fishing boat with one (one row) fish collecting light using direct light and reflected light.

  Hereinafter, the present invention will be described in more detail using preferred embodiments. However, the following embodiments are merely examples embodying the present invention, and the present invention is not limited thereto.

(Embodiment)
A fish collection lamp according to an embodiment of the present invention will be described with reference to FIGS. In order to make the explanation easy to understand, each figure is provided with an arrow indicating a direction. The fish collecting lamp 1 includes a lamp cover main body 2, a reflector main body 3 provided in the lamp cover main body 2, and a light source 4 attached to the inside of the reflector main body 3. The lamp cover main body 2 has the cover frame portions 2b and 2b in a state where the cover frame portions 2b and 2b of the pair of left and right symmetrical covers 2a and 2a are attached, except for the power cable mounting portion (not shown). A substantially U-shaped frame 5 is fitted to the frame 5 from above, and openings (5b, 2h, 5b) provided at the four corners of the frame 5 and the corresponding four corners of the cover frame portions 2b, 2b. , 2h...), And screwing means (5a, 5a,...) Such as a bolt / nut pair are screwed into the frame 5 and the cover frame portions 2b, 2b. Yes.

  As shown in FIG. 1, the lamp cover main body 2 has a pair of light transmission window portions 2 c and 2 c for transmitting light emitted from the light source 4 on the left and right side surfaces in a rectangular shape. A window frame portion 2e is formed around the portions 2c and 2c. In order to close the light transmission window portions 2c and 2c, for example, transparent plates 2d and 2d formed of an acrylic plate are waterproofed and attached to the inner wall of the window frame portion 2e. The lamp cover body 2 is made of a lightweight metal material. In FIG. 1, the side where the entire light transmission window 2c is visually recognized is the left side, and the light transmission window 2c side disposed opposite is the right side, and the opening side of the substantially U-shaped frame 5 is the opening side. The lower side and the opposite side of the opening side are the upper side, the side surface side of the lamp cover main body 2 being viewed is the front side, and the opposite side surface side is the rear side.

  A reflector main body 3 is provided in the lamp cover main body 2. As will be described in detail later, the reflector main body 3 is attached in a standing state to the bottom reflector 3a formed in a curved state toward the inside of the lamp cover main body 2 and the front and rear ends of the bottom reflector 3a. A pair of front and rear side reflectors 3b and 3b, and a top reflector 3c having both ends attached to the upper ends of the front and rear side reflectors 3b and 3b. All the left and right surface sides of the reflector main body 3 are opened. The reflector main body 3 is formed with a mirror surface at least on the entire inner surface.

The light source 4 is an electrodeless discharge lamp in which ferrite cores 4b and 4b are provided on the left and right sides of a closed-loop and square-shaped glass tube 4a, and a lamp fixture integrally formed on each of the left and right ferrite cores 4b and 4b. 4c and 4c are screwed and fixed to the front and rear side reflectors 3b and 3b.

And is converted into visible light. In addition, mercury vapor | steam is not enclosed in the glass tube 4a of a present Example.

  Since the electrodeless discharge lamp has no electrode in the arc tube (glass tube), it has a very long life (for example, the external electromagnetic induction type used in the present invention has a life of 100,000 hours), so that maintenance is difficult. It is useful to use as a fishing light for a fishing boat. In addition to being brighter than the actually measured illuminance, the lamp temperature at the time of lighting is low, so that an economic effect is great. In addition, there are advantages such as no flickering of light and instant lighting / relighting possible.

  The lamp cover body 2 has a substantially sector shape in which the pair of covers 2a and 2a are each composed of a bottom portion 2g and 2g, a substantially arc-shaped top portion 2f and 2f, and window frame portions 2e and 2e in a front view. I am doing. In addition, a power cable attachment part, a power cable, a ballast, etc. are not illustrated. The top portions 2f and 2f of the lamp cover main body 2 have a substantially arc shape and are rounded on the upper side, and the bottom side portions 2g and 2g are slightly rounded on the lower side. The widths of the top portions 2f and 2f are formed wider than the widths of the bottom side portions 2g and 2g, and the left window frame portion 2e has a shape inclined leftward from the left bottom side portion 2g toward the left top portion 2f. There is no. The right window frame portion 2e has a shape inclined rightward from the right bottom portion 2g toward the right top portion 2f. The angle formed by the left window frame 2e and the left base 2g is set to about 125 degrees in the embodiment shown in FIG. 4, but this angle is appropriately adjusted as necessary. The same applies to the angle formed by the right window frame portion 2e and the right bottom portion 2g.

  Next, the reflector main body 3 will be described with reference to FIGS. 6 to 9, 11, 15, and 17. The reflector main body 3 is installed in the lamp cover main body 2 as described above. The bottom reflecting plate 3a is formed to be curved in the inner direction of the lamp cover body 3, that is, on the upper side (for example, formed in a front view and an arc in FIG. 7), and the light source 4 ( Part of the direct light emitted from FIG. 1) is reflected in the direction of the top reflector 3c. The pair of front and rear side reflectors 3b and 3b are attached to the front and rear ends of the bottom reflector 3a so as to face each other in an upright state. In this state, both front and rear ends of the top reflector 3c are attached to the upper ends of the front and rear side reflectors 3b and 3b. The top reflector 3c has a configuration in which top reflectors 3c1, 3c2, 3c3, and 3c4 are arranged in order from the left side when viewed from the front, and is substantially M-shaped when viewed from the front.

  The angle formed by the left window frame portion 2e and the left bottom portion 2g, the angle formed by the right window frame portion 2e and the right bottom portion 2g, and the angle between the top reflecting pieces continuously provided on the top reflecting plate 3c (that is, The angle formed between the top reflecting piece 3c1 and the top reflecting piece 3c2, the angle formed between the top reflecting piece 3c2 and the top reflecting piece 3c3, and the angle formed between the top reflecting piece 3c3 and the top reflecting piece 3c4.) Of the bottom reflecting plate 3a The curvature (that is, the degree of bending of the curve) determines the reflection angle of the direct light (incident light) emitted from the light source 4, and the fish collection system using the fish collection lamp 1 and the fish collection lamp 1 is mounted. The angle of reflection is adjusted to the optimum angle according to the structure of the fishing boat, the degree of shaking of the fishing boat according to the sea surface condition during fishing, the capture method and means, etc.

  The bottom reflector 3a is formed by adjusting the curvature (that is, the degree of bending) so that all the direct light incident from the light source 4 is reflected toward the top reflector 3c without waste. The The top reflector 3c is formed by adjusting the reflection angle so that all the direct light incident from the light source 4 is reflected to the outside without waste. Naturally, the angle and light intensity at which the direct light and the reflected light are radiated outward are set symmetrically (see FIGS. 11, 15, and 17).

  In the present embodiment, as shown in FIG. 7, the top reflector 3c has a top reflector piece 3c1 and a top reflector piece 3c2 arranged in a mountain shape in order from the left side so as to show a substantially M shape in a front view. The top reflecting piece 3c2 and the top reflecting piece 3c3 are connected in a valley shape, the top reflecting piece 3c3 and the top reflecting piece 3c4 are connected in a mountain shape, and the top reflecting piece 3c1 and the top reflecting piece 3c2 Angle (reflection angle θ1), top reflection piece 3c2 and top reflection piece 3c3 (reflection angle θ2), and top reflection piece 3c3 and top reflection piece 3c4 (reflection angle θ3) When the mounted fish collecting lamp 1 emits light, it is formed at an angle so that the light intensity in the linear direction connecting the light source 4 and the edge of the fishing boat is maximized. In one embodiment, the width of the fishing boat is about 5 m, the height of the fishing light mounting from the deck surface is about 2.8 m, θ1 = 145.5 degrees, θ2 = 163.0 degrees, θ3 = 145.5 degrees. Is formed. Of course, these reflection angles θ1, θ2, and θ3 need to be adjusted as appropriate according to the width of the fishing boat and the height of the fishing light. However, as a result of earnest examination by the present applicant, the fish collecting effect is improved. In order to achieve this, if the range is set to 140.5 degrees ≦ θ1 ≦ 150.5 degrees, 158.0 degrees = <θ2 <= 168.0 degrees, 140.5 degrees = <θ3 <= 150.5 degrees, I found a good thing.

  On the left and right surface sides of the reflector main body 3, the reflector is opened on the entire surface so as to irradiate the direct light emitted from the light source 4 and the reflected light of the reflectors 3a, 3b, 3b, 3c toward the outside. Openings 3f and 3f are formed. The reflector openings 3f and 3f are surrounded and opened by the edge of the bottom reflector 3a, the edges of the front and rear side reflectors 3b and 3b, and the edge of the top reflector 3c. The bottom reflection plate 3a, the front and rear side reflection plates 3b and 3b, and the top reflection plate 3c are formed with at least an inner surface as a mirror surface. In the present embodiment, the bottom reflector 3a, the front and rear side reflectors 3b and 3b, and the top reflector 3c are formed of a stainless steel plate whose inner surface is mirror-finished, but a material that has a predetermined effect on the reflection efficiency. As long as it is not particularly limited to the stainless steel plate, other materials may be used.

  Small-diameter apertures 3d and 3d provided at substantially central portions of the front and rear side reflectors 3b and 3b are apertures for screwing the lamp fixtures 4c and 4c of the light source 4 into the interior of the reflector body 3. It is. A cable insertion hole 3e for inserting a power cable (not shown) is opened on the front side of the bottom reflector 3a.

  FIG. 10 is an exploded perspective view of the fish collecting lamp 1. Since the individual members constituting the fish collection lamp 1 have been described above, the description thereof is omitted here. Hereinafter, the assembly procedure of the fish lamp 1 will be described. First, the light source 4 is attached to the reflector main body 3. At this time, the lamp fixtures 4c and 4c are screwed and fixed to the front and rear side reflection plates 3b using separate lamp fixtures 3g and 3g and screwing means (not shown).

  Next, the left and right covers 2a, 2a, in which the transparent plates 2d, 2d are waterproofed and adhered to the inner walls of the window frame portions 2e, 2e, are mounted on the reflector main body 3 to which the light source 4 is attached. . At this time, first, the lamp fixing tool 2i attached to the cover frame 2b of the left cover 2a is screwed and fixed using the screwing means 3g. The left and right covers 2a and 2a are in a state where the left and right cover frame portions 2b and 2b are attached. In this state, the frame 5 is attached to the cover frame portions 2b and 2b from above, and the opening portions (5b, 5b,...) At the four corner portions of the frame 5 and the four corner portions of the cover frame portions 2b and 2b are opened. Screw means (5a, 5a,...) Such as bolt / nut pairs are screwed through the holes (2h, 2h,...), And the cover frame portions 2b, 2b are fixed. In this way, the fish lamp 1 can be easily assembled.

FIGS. 11-13 has shown the fishing boat carrying the fish collection system comprised using the fish collection light 1 mentioned above. In addition, in FIGS. 11-18, the left side of a figure shows the starboard side of a fishing boat, and the right side of a figure shows the port side of a fishing boat.
The fish collection system 10 of a fishing boat is configured by arranging a plurality of fish collection lights 1 in a row along the hull center line of the fishing boat 100. The fish collection lamp 1 is provided with a fish collection lamp control device such as a power cable (not shown) and a ballast. The fish collection lamp system 10 has a predetermined number of fish collection lamps 1 attached to a support line 15 that is stretched by connecting a support base 14 and a hull superstructure 12 provided at the center of the bow of a fishing boat 100. A predetermined number of fish lamps 1 are attached to a support line 17 that is stretched by connecting a hull superstructure 12 and a support base 16 provided at the center of the stern. The interval and the number of the support bases 14 and 16 are appropriately adjusted as necessary. A fishing boat 100 includes a hull 11, a hull superstructure 12, and a propulsion / steering unit 13, and is equipped with a fishlight system 10 according to the present invention.

  The irradiation range of the direct light from the light source 4 of the fish collection lamp 1 and the reflected light from the reflector main body 3 in the fish collection system 10 of a present Example is typically shown in FIG. As shown in the drawing, the irradiation area of the light irradiated from the left light transmission window 2c is the left irradiation area a1 surrounded by the line r1 and the line r2, and the irradiation of light irradiated from the right transmission window 2c. The region is a right irradiation region a2 surrounded by the lines r3 and r4. The overlapping portion of the left irradiation region a1 and the right irradiation region a2 becomes the irradiation region of the fish lamp 1. For this reason, it is possible to simultaneously irradiate light on the port side and starboard sea surface sl of the fishing boat 100 and the deck of the fishing boat 100 with one (one row) of the fish collecting lights 1. As shown in the figure, the black-painted portion b3 immediately below the fishing light 1 is not formed with either the left irradiation area a1 or the right irradiation area a2 and is a non-irradiation area (dark area), but is above the deck. There is no effect on the deck work. The direct light and reflected light irradiated on the sea surface sl in the port and starboard directions of the fishing boat 100 have reached a predetermined depth in the sea.

  The left and right black portions of the fishing boat 100 are shadows of the fishing boat 100 and are non-irradiated areas b1 and b2 where the light from the fish collection lamp 1 is not irradiated. Here, as described above, the direct light and the reflected light emitted from the fish collection lamp 1 form the reflection angles θ1, θ2, and θ3 at predetermined angles, thereby forming the light source 4 and the left and right edges of the fishing boat 100. It is optimally set so that the light intensity in the direction of the connected lines r5 and r6 is maximized. With this configuration, the boundary between the non-irradiated regions b1 and b2 that are squid capture regions and the irradiated regions a1 and a2 becomes clear, that is, the non-irradiated regions b1 and b2 and the irradiated regions a1 and a2 are separated from each other. The difference between light and dark becomes large, and the fish collection effect can be greatly improved. At the same time, the fishing effect can be greatly improved.

  In addition, in FIGS. 11-13, the attachment height to the support stands 14 and 16 of the fishlight 1 is suitably adjusted as needed. For example, as shown in the modification of FIG. 14, in the fishing boat 101, the attachment height of the fish collecting lamp 1 may be attached at a position higher than the hull superstructure 12 above the support bases 14, 16, 18. .

  FIG. 15 shows a light distribution curve of the fish collection lamp 1 of the present invention. A curve A1 shows the characteristics of the vertical inner surface perpendicular to the tube axis (ramp axis), and a curve A2 shows the characteristics of the vertical surface parallel to the tube axis. The light distribution curve indicates in what direction and how much light intensity (cd; candela) is emitted from the lighting device, and is well known in the technical field of lighting devices. As described above, the fish lamp 1 according to the present invention has an angle (reflection angle θ1) between the top reflecting piece 3c1 and the top reflecting piece 3c2, and an angle (reflection angle θ2) between the top reflecting piece 3c2 and the top reflecting piece 3c3. When the angle (reflection angle θ3) formed between the top reflecting piece 3c3 and the top reflecting piece 3c4 is emitted by mounting the fishing lamp 1 on the fishing boat, the light intensity in the linear direction connecting the light source 4 and the edge of the fishing boat is Since it is formed at an angle that maximizes the light distribution curve, the right and left specific directions exhibit higher light intensity characteristics than those immediately below the light source 4 as shown by the curve A1 in FIG. This specific direction is the linear direction connecting the light source and the edge of the fishing boat. The light intensity is symmetrical. As described above, the irradiation region is a bright region where light is irradiated, and is a region where plankton and small fish having positive phototaxis gather. The non-irradiated region is a dark region where no light is irradiated, and is a region where squid gathers to supplement plankton and small fish collected in the irradiated region. The boundary between the irradiated region and the non-irradiated region is clearly formed. That is, by increasing the difference in brightness between the irradiated region and the non-irradiated region, the fish collection effect in the non-irradiated region of squid is greatly improved, and therefore the fishing effect is also greatly improved. Of course, the area where squid can be captured is set within this non-irradiated area.

  FIG. 16 is a light distribution curve of a fish collection lamp shown as a reference example. The fish collection lamp of this reference example is configured by using a conventional mercury lamp that irradiates light in all directions as shown in FIG. A curve A3 indicates the characteristics of the vertical inner surface perpendicular to the tube axis, and a curve A4 indicates the characteristics of the vertical surface parallel to the tube axis. As shown in the figure, since light is radiated in all directions, the ratio of light radiated to other than the sea surface is large, and the radiation efficiency to the sea surface is very low. For this reason, conventionally, when a fishing light having such characteristics is mounted on a fishing boat, one having very large power consumption has been used to ensure a predetermined brightness in the sea surface direction.

  FIG. 17 is an illuminance distribution diagram when the fish collection system 10 using the fish collection lamp 1 of the present invention is mounted on a fishing boat 100 and the sea surface is illuminated by the fish collection lamp 1, and each curve shown in FIG. It is. The power consumption per one electrodeless discharge lamp of the light source is 200W. The fish collection system 10 is configured by arranging a plurality of fish collection lamps 1 in a row along the hull center line of the fishing boat 100. The unit of illuminance is Lux. The isoilluminance curve in the center of FIG. 17 shows the illuminance distribution on the deck of the fishing boat. The left and right iso-illumination curves in FIG. 17 indicate the illuminance distribution on the starboard side sea surface sl of the fishing boat 100 and the illuminance distribution on the port side sea surface sl of the fishing boat 100, respectively. The gap between the illuminance distribution at the center of FIG. 17 and the illuminance distribution on the left and right chords is a non-irradiated region. FIG. 18 is an illuminance distribution diagram when the fish collection system using the fish collection light of the reference example is mounted on a fishing boat and the sea surface is illuminated with the fish collection light, and each curve shown in the figure is an isoluminance curve. Similar to the present invention, the same number of fish collecting lights are arranged in a line along the hull center line of the fishing boat. As the light source, the conventional mercury lamp described with reference to FIG. 16 is used, and the power consumption per one mercury lamp is 1000 W. The unit of illuminance is Lux. The isoilluminance curve in the center of FIG. 18 shows the illuminance distribution on the deck of the fishing boat. The left and right isoilluminance curves in FIG. 18 respectively show the illuminance distribution on the starboard side of the fishing boat and the illuminance distribution on the port side of the fishing boat. The gap between the illuminance distribution at the center of FIG. 18 and the illuminance distribution on the left and right chords is a non-irradiated region. Note that the isoilluminance curve and the illuminance distribution diagram are well known to those skilled in the art belonging to the technical field of illumination devices.

  The isoilluminance curve interval at the boundary between the non-irradiated region and the irradiated region along the left and right anchors of the fishing boat 100 in FIG. 17 and the boundary portion between the non-irradiated region and the irradiated region along the left and right anchor of the fishing boat in FIG. When compared with the interval of the isoilluminance curve, the direction of FIG. This indicates that the boundary between the irradiated region and the non-irradiated region is clearer in FIG. 17 than in FIG. That is, the difference in brightness between the irradiated region and the non-irradiated region is larger in FIG. 17 than in FIG. Therefore, it can be understood that the fish collection effect / fishing effect of the fishing boat 100 using the fish collection lamp 1 having the illuminance distribution of FIG. 17 is improved as compared with the fishing boat using the fish collection lamp having the illuminance distribution of FIG.

  Further, as can be seen from a comparison between FIG. 17 and FIG. 18, the illuminance values on the decks and the illuminance on the sea surface are almost the same. As described above, the power consumption of the mercury lamp used in the fish lamp of FIG. 18 is 1000 W, and the power consumption of the electrodeless discharge lamp used in the fish lamp 1 of FIG. 17 is 200 W. In other words, the fishlight lamp 1 of the present invention has the structure described in the above-mentioned paragraphs “0035” to “0048” (embodiment), thereby improving the irradiation efficiency in the sea surface direction of the left and right sea bream, and thereby the conventional mercury lamp Compared to a fish-collecting light using, a significant reduction in power consumption of 1/5 can be realized.

  As described above, in the fishing boat 100 equipped with the fish collection light system 10 of the present invention, it is possible to irradiate a wide range of collection light, enhance the effect of collecting the fish, and obtain a predetermined fishing result (fishing effect). Worker visibility and work efficiency can be improved. Although squid fishing has been mainly described, even in the case of fishing of fish having traveling properties, the direction and light intensity of irradiation light are optimally adjusted by appropriately adjusting the reflection angle of the top reflector and the curvature of the bottom reflector. By setting the conditions, the fish collection effect and the catch effect can be greatly improved.

  The fish lamp of the present invention can be used not only as a fish lamp for fishing boats but also as a general lighting device. For example, on a platform in a station, it is safer for the user to brighten the end of the platform, but a lighting device cannot be provided at the end of the platform for the safety of the vehicle. Therefore, conventionally, a lighting device is provided inside the home. However, in the conventional lighting device, the light intensity directly below the lighting device is high, and the light intensity decreases as the distance from the lighting device increases. That is, the inside of the home is bright and the end of the home is dark. However, the fish lamp according to the present invention can irradiate light over a wide range and change the light intensity in a specific direction by changing the reflection angle of the reflecting piece constituting the top reflector, Even if an illuminating device that uses the technology of fish-collecting lamps is installed inside the home, it is possible to illuminate the edge of the home away from the installation location with lower power consumption than in the conventional illuminating device. Such an illumination device (illumination technology) can also be used as a general outdoor illumination device (illumination technology) installed in parks, roads, streets, and the like.
