Description

FISHING LIGHT

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing net using a light emitting diode (LED) in order to collect fishing fish such as saury with efficient light from a ship on a fishing boat.

The pick-up lamps installed on the fishing boat are used to place multiple light sources (natural light bulbs, metal helide lamps) in the vicinity of the hull, and to survey and collect the fish from the ship. In fishing vessels such as saury fish or squid fishing, it is possible to catch fish by using the habit of keeping the fish catching near the hull by illuminating the water surface on both sides of the hull by lighting the fishing lights at night.

In recent years, in order to reduce power consumption, a blue LED for emitting blue light or a red LED for emitting red light as a light source has been proposed in place of a metal helide lamp or a natural lamp (for example, Japanese Patent Laid- 84925).

For example, when a red LED is used in place of a red light bulb formed by applying a red paint to a natural lamp, since the same light intensity can be provided at a much lower power, power can be saved greatly, The cost can be greatly reduced.

However, due to LED pick-ups using red LEDs in place of red light bulbs, when saury is actually used, saury does not react to this kind of LED pick-up light exactly the same as that of a conventional pick-up using a red light bulb, When fishing is carried out with the fish, the catch is greatly reduced.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a pinchlight using an LED which can obtain an equivalent response to a fish such as saury, even when the pinch torch is operated by the same method as that of a conventional red bulb.

It is an object of the present invention to provide a fishing rod using an LED which can keep a fish such as saury in good condition and does not reduce the catch amount.

According to the present invention, it is possible to provide a false white LED which is formed by combining phosphors on blue LEDs and a visibility of fish arranged on the light irradiation side of the pseudo white LED A headlight with a red transmission filter having a high degree of light attenuation in a high wavelength region is provided.

Due to the combination of the pseudo white LED and this special red transmission filter, the irradiance is almost zero in the high wavelength region of the fish, as in the conventional red light bulb, and in the red region, The spectral distribution gradually changes in the red region without increasing abruptly. Therefore, even when the conventional red bulb is substituted for the fish such as saury and the fish is operated by the same method as that, the fish can be kept in good condition, and the catch does not decrease. Of course, since LEDs are used, the power consumption can be greatly reduced and the lifetime is also considerably long.

A housing body for housing at least a plurality of pseudo white LEDs and an LED substrate therein; and a transparent cover member sealingly mounted on the front surface of the housing body, Is preferably a red transmission flat plate type filter arranged on the light irradiation side of the plurality of pseudo white LEDs separately from the cover member.

And a cover member sealingly installed on the front surface of the housing body, wherein the red light-permeable filter includes a plurality of pseudo white LEDs, It is preferable that the cover member is the above-described cover member which also serves as a red transmission flat plate type filter.

The red transmission flat plate type filter is preferably a red transparent acrylic plate.

The red transmission flat plate type filter is preferably a red vinyl chloride plate.

The red transmission flat plate filter is preferably constructed by attaching a red transmission filter layer on the transparent plate.

A housing body for housing at least a plurality of pseudo white LEDs and an LED substrate therein; and a transparent cover member sealingly mounted on the front surface of the housing body, Is a red transmission filter layer deposited on each front surface of the pseudo white LED.

It is preferable that the red transmission filter layer is formed by applying a red paint.

According to the present invention, fishes such as saury are replaced with conventional red light bulbs, and fishes can be kept in good condition even when the fish pail is operated by the same technique as that technique, and the catch amount is not reduced. Of course, since the LED is used, the power consumption can be greatly reduced and the lifetime is also considerably long.

Fig. 1 and Fig. 2 schematically show a configuration example of a picker as a first embodiment of the present invention.

1, the booklet lamp of the first embodiment includes a body member 10 having a cooling fin 10a formed on its back surface, a transparent flat plate-like cover 10 disposed on the front surface of the body member 10, The frame member 11 and the frame member 12 sealingly arranged by using the plurality of bolts 13 and the seal member 14 by sandwiching the cover member 11 between the body member 10 have. The body member 10 and the frame member 12 form an aluminum material by die casting, and the cover member 11 is formed of a light-transparent transparent resin material, for example, polycarbonate. The body member 10 and the frame member 12 constitute a housing body, and the housing and the cover member 11 are sealed so that the inside is watertight.

As shown in Figs. 1 and 2, an LED substrate 15 is fixed to the body member 10 by means of bolts 16 or the like, inside the housing body. On the surface of the LED substrate 15, a plurality of chip-type LEDs 17 (105 in the example of FIG. 1) are fixed in an arrangement as shown in FIG. In the LED substrate 15, printed wiring portions electrically connected to these chip-type LEDs 17 are formed. Further, a power source circuit such as a driving resistor and a constant current IC electrically connected to the printed wiring portion is mounted. These power supply circuits are connected to the power cable 19 via a waterproof socket 18 provided in the body member 10. [

In the inside of the housing, a single plate-shaped filter is provided on the front surface of the chip-type LED 17 as a red transmission filter 20. Light emitted from the chip-type LED 17 passes through the plate- Is configured to be radiated to the outside through the cover member (11).

The chip-type LED 17 is a pseudo white LED formed by combining a blue LED with a phosphor. In the present embodiment, for example, NS6W183A manufactured by Nichia Corporation is used. FIG. 4 shows the spectrum distribution of the emission intensity of the pseudo white LED. Here, the abscissa indicates the wavelength (nm) and the ordinate indicates the relative luminescence intensity.

The plate-like filter as the red transmission filter 20 is a filter having a high degree of light attenuation in a wavelength region where the visibility of fish (for example, saury) is high. In addition, saury has the maximum visibility for light with a wavelength in the vicinity of 470 to 500 nm. The red transmission filter 20 of this embodiment uses a transparent acrylic plate having a thickness of 2.0 mm, for example, a red transparent acrylic plate such as an infrared transparent Sunday plate manufactured by Acrylic Sunday KK. Fig. 5 shows the spectrum distribution of the irradiance when this red transparent acrylic plate is used as the red transmission filter 20. Fig. The abscissa indicates the wavelength (nm), and the ordinate indicates the relative azimuth. As the light source, the above-described pseudo white LED is used.

FIG. 6 shows spectral distributions of radiation intensities of various light sources used in a pick-up, and FIG. 6 (A) is a spectrum distribution of light emitted by a light source (without a red transmission filter) (C) shows the emission spectrum spectrum distribution when the pseudo white LED is used as the light source and the red transparent acrylic plate of the first embodiment is used as the red transmission filter 20, (D) shows the spectrum distribution of the irradiance spectrum due to the light emitted from the conventional red bulb (500 W) coated with a red paint on a white bulb as a light source, and have. 6, the abscissa indicates the wavelength (nm) and the ordinate indicates the irradiance (μm / c m2 / nm).

6 (B) and 6 (D), the spectral distribution (B) of the irradiance by the combination of (pseudo white LED) + (red transparent acrylic plate) It is almost zero in a wavelength range (470 to 500 nm) in which the visibility of the saury is high, similarly to the spectrum distribution (D) of the illuminance by the red bulb, and in the red region like the red LED, And has a spectral distribution that varies with time.

Fig. 7 illustrates an example in which a fishing rod is actually mounted on a fishing boat as in this embodiment.

In the same figure, reference numeral 70 denotes a fishing line of a saury bar bracket net fishing fishery, 71 to 73 are fishing nets attached to a pawl 74 extending from a fishing boat 70, And the saury (77) shows the rod bracket netting, respectively. The fishing boat 70 is provided with a plurality of pawls 74 toward its periphery, and a single or a plurality of catch lights are provided on the respective pawls 74 toward the sea surface. In the case of fishing boat 70 of the saury bar bracket net fishing fishery, as a fishing rod, a fishing boat using a metal helide lamp, a blue LED, a white LED, a halogen lamp and an incandescent lamp as light sources, A red pick-up lamp is installed. Depending on the technique of saury catching, most of the lantern lights are red pickers.

First, the saury catcher turns on the light by a metal helide lamp or a searchlight, a blue LED or a white LED, a halogen lamp or an incandescent lamp, and collects saury with a strong white light. Subsequently, by the operation such as turning off the lights around the fishing boat sequentially and turning on the lights, the crowd of saury is guided to turn around the fishing boat, and finally it is guided into the net of the rod bracket and caught. At the time of catching, an operation is carried out to illuminate the red pick-up lamp at last and to raise the saury crowd upwards. In addition, when we irradiate strong light of white light system continuously, because saury is scattered, we turn on red catch light and let saury stay in upper layer around fishing boat long.

As described above, the sensitivity of saury is high for the blue region of 470 to 500 nm in the wavelength region and considerably lower in the red region of the wavelength of 580 nm or more. In addition, the light in the red region tends to irradiate only the upper layer without reaching the deep portion in the sea water.

FIG. 8 shows spectral distributions of the light transmittance of sea water by depths of 0.5 m, 1 m, 5 m and 10 m. Figs. 9 to 12 show spectral distributions of irradiance by various light sources obtained by using the spectral distribution of the light transmittance. FIG. 9 shows a case where the depth is 0.5 m, FIG. 10 shows the case where the depth is 1 m, FIG. 11 shows the case where the depth is 5 m, and FIG. 12 shows the case where the depth is 10 m. 9 to 12, the abscissa indicates the wavelength (nm) and the ordinate indicates the irradiance (μm / cm 2 / nm).

9 to 12, (a) shows a case where a red LED is used as a light source, (b) shows a case where a conventional white bulb (500 W) is used as a light source, In the case where a conventional red bulb 500W is used and the pseudo white LED is used as a light source and a polycarbonate plate + 3), respectively.

In the case of the red LED of (a), the irradiance value becomes excessively large at any depth, so that the saury does not stay near the fishing boat and runs away. In the case of the conventional white light bulb (500 W) of (b), the irradiance value is large in the region where the visibility of the saury is high even at the depth of 5 m and the depth of 10 m. The saury does not rise upward and runs away. On the other hand, in the case of the conventional red bulb (500W) of (c), since the irradiance value in the wavelength range of 470 to 500 nm with a high visibility of saury is relatively low at any depth, the saury is gathered upward, Stay for a long time. (d), the irradiance value in the wavelength region of 470 to 500 nm, which is high in the visibility of the saury, is comparatively low at any depth, like the conventional red bulb 500W of (c). At a depth of 10 m, the irradiance value in the region of wavelengths of 480 nm or less increases, but in this region, the visibility of the saury is low, which is not a problem.

As described above in detail, according to the present embodiment, as in the case of the conventional red light bulb, almost zero is obtained in the wavelength region of 470 to 500 nm where the visibility of the saury is high, and in the red region such as the red LED, It is possible to obtain a radiance of a spectral distribution that changes gently. Therefore, it is possible to substitute the conventional red bulb for fish such as saury, and to keep the fish such as saury in good condition even when the fishing rod is operated by the same technique as that technique, and the catch does not decrease. Of course, since LEDs are used, power consumption can be greatly reduced and the lifetime is also considerably long.

Fig. 13 shows spectral distribution characteristics of the irradiance of a white LED that has passed through a red transmission filter according to the second embodiment of the present invention.

In the present embodiment, the configuration of the flat panel filter as the red transmission filter 20 is different from that of the first embodiment, and the other configuration is completely the same as that of the first embodiment. Therefore, the following description is made only for different parts of both. The same reference numerals are used for the same constituent elements in both embodiments.

The red transmission filter 20 of the present embodiment is also a filter having a high light attenuation degree in a wavelength region where the visibility of a fish (for example, saury) is high. The red transmission filter 20 of the present embodiment uses, for example, a red vinyl chloride plate of Koeido Co., Ltd. and a plate of a red vinyl chloride thickness of 0.4 mm. Fig. 13 shows the spectrum distribution of the irradiance of the red transmission filter 20 when the red vinyl chloride plate is used. The abscissa indicates the wavelength (nm), and the ordinate indicates the relative azimuth. As the light source, the above-described pseudo white LED is used.

In Fig. 6, (E) shows the emission spectrum spectrum distribution in the case of using the pseudo white LED as the light source and using the red vinyl chloride plate of the second embodiment as the red transmission filter 20. Fig.

6 (E) and 6 (D), the emission spectrum spectrum E is obtained by combining the (pseudo white LED) + (red vinyl chloride plate) as in the present embodiment, As in the case of the spectrum distribution (D) of the emission intensity by the bulb, it is almost zero in the wavelength range (470 to 500 nm) where the visibility of the saury is high, and gradually increases in the red area like the red LED And has a varying spectrum distribution. Also, although the irradiance value in the region near the wavelength (450 nm) is somewhat higher, the visibility of the saury is low in this region, so this is not a problem.

Therefore, according to the present embodiment, as in the case of the conventional red light bulb, the saury becomes almost zero in the wavelength region (470 to 500 nm) at which the visibility of the saury is high, and is gradually increased in the red region like the red LED It is possible to obtain the emission illuminance of the changing spectral distribution. Therefore, it is possible to substitute the conventional red bulb for fish such as saury, and to keep the fish such as saury in good condition even when the fishing rod is operated by the same technique as that technique, and the catch does not decrease. Of course, since LEDs are used, power consumption can be greatly reduced and the lifetime is also considerably long.

Fig. 14 shows the spectral distribution of the irradiance of the white LED through the red transmission filter of the third embodiment of the present invention.

In the present embodiment, the configuration of the flat panel filter as the red transmission filter 20 is different from that of the first embodiment, and the other configuration is exactly the same as that of the first embodiment. Therefore, the following description is made only for the different parts of both. The same reference numerals are used for the same constituent elements in both embodiments.

The red transmission filter 20 of the present embodiment is also a filter having a high light attenuation degree in a wavelength region where the visibility of a fish (for example, saury) is high. The red transmission filter 20 of the present embodiment is obtained by attaching a red transmission filter layer on a transparent flat plate made of a transparent polycarbonate plate such as Caboglas SG-AH of Asahi Glass Co., Ltd. and having a thickness of 3.0 mm. The red transmission filter layer may be any of a paint layer, a film layer, and the like, provided that it has the same spectrum distribution as that of the red transmission filter 20 of the first and second embodiments. Here, have. As the red printing ink, for example, the 14th edition 155 magenta of DIC Graphics Co., Ltd. is used. Fig. 14 shows the spectrum distribution of the irradiance of the red-transparent filter 20 when the transparent polycarbonate plate coated with the red paint is used. Here, the abscissa indicates the wavelength (nm), and the ordinate indicates the irradiance (μm / cm 2 / nm). As the light source, the above-described pseudo white LED is used.

6, (F) to (H) show a case where the pseudo white LED is used as a light source and the transparent polycarbonate plate of the third embodiment is coated with a red paint using the red transmission filter 20 And the illuminance spectrum distribution is shown. (F) is a case where the coating thickness of the red paint is comparatively small, (G) is a case where the coating thickness of the red paint is medium, and (H) is a case where the coating thickness of the red paint is relatively thick.

6 (F) to 6 (H) and 6 (D), the spectrum of the irradiance by the combination of (pseudo white LED) + (polycarbonate plate) + The distributions (F) to (H) are almost zero in the wavelength range (470 to 500 nm) where the visibility of the saury is high as in the spectrum distribution (D) of the irradiance of the conventional red bulb, And has a spectral distribution that changes gently in the red region without increasing abruptly. In addition, although the irradiance value in the region near the wavelength of 450 nm is somewhat higher, the sensitivity of the saury is low in this region, so that this is not a problem.

Therefore, according to the present embodiment, as in the case of the conventional white light bulb, almost zero in the wavelength range of 470 to 500 nm, which is high in the visibility of the saury, and gradually changes in the red region such as the red LED, The radiation illuminance of the spectrum distribution can be obtained. Therefore, it is possible to substitute the conventional red bulb for fish such as saury, and to keep the fish such as saury in good condition even when the fishing rod is operated by the same technique as that technique, and the catch does not decrease. Of course, since LEDs are used, power consumption can be greatly reduced and the lifetime is also considerably long.
