Description

  The present invention relates to a fishing light for a fishing industry, which is a light irradiation device used to collect a school of fish using the property that fish gather in light.

Conventionally, multiple blue light emitting diodes have been used to provide a light collection lamp that has high light irradiation efficiency to the sea surface, which can increase fishing efficiency, improve fishing boat fuel economy and inboard environment, and does not hinder fishermen's health. These are arranged in a matrix on the substrate to constitute an LED (light emitting diode) planar light source, and two LED planar light sources are used to illuminate the right sea surface of the ship, Combined as a left side light source that illuminates the left sea surface. The left and right LED planar light sources irradiate light only on the sea surface, and the blue light emitted by the light-emitting diode has little light attenuation in water, and the emission wavelength itself is the optimum wavelength for collecting squid and other fish. As a result of these synergistic effects, there has been proposed a fishing light that requires much less power to obtain the same catch (see, for example, Patent Document 1).
JP 2003-134967 A

  However, each LED has a low luminous intensity (about 2 cd (candela)), and it is necessary to arrange a very large number of LEDs on a substrate when trying to obtain the luminous intensity equivalent to that of a conventional fish-collecting light source. Has a problem of increasing the size of the case on which the LED is mounted.

  In general, a fishing light is installed by suspending it from the wire passed to the pillars installed on the front and rear of the fishing boat's deck. Located higher than the bridge. By installing a large number of large LED fishing light cases at such a high position, the center of gravity of the fishing boat becomes higher, so it becomes a so-called top heavy, reducing the resilience of the fishing boat, and may cause a capsizing accident in stormy weather Is done.

  When the power unit of the fish collection lamp is integrated with the fish collection lamp case, the weight of the LED fish collection lamp case further increases.

  Further, when a large number of LEDs are arranged on a substrate to be a surface light source, it is necessary to cool the heat generated from the LEDs in order to maintain the luminous intensity and long life. In an LED fishing light in which a bullet-type LED is arranged on a resin substrate, the LEDs on the substrate are not electrically insulated, and it is necessary to cool the substrate from the top after enclosing the substrate with an insulating cover. Therefore, a large-scale cooling device such as forced air cooling or water cooling is required. This leads to a further increase in the weight of the LED fishing light case.

  The present invention has been made to solve the above-described problems, and can collect a necessary amount of light as a fishing light without deteriorating the resilience of a fishing boat, and can use a small and lightweight light-emitting diode. The purpose is to provide lights.

  A fish collecting lamp according to the present invention includes a light emitting diode module configured to cover a substrate with a case with a condensing lens in which the light emitting diode is mounted on the substrate and a condensing lens is formed facing the light emitting diode, and a plurality of light emitting diode modules A light source unit having a main board on which a light emitting diode module is mounted, a waterproof case having a light transmissive cover on a surface facing the light emitting diode module, and supplying power to the light source unit And a power supply unit.

  Further, the fish collection lamp according to the present invention is characterized in that the luminous intensity per light emitting diode of the light emitting diode module is 33 cd (candela) or more.

  Further, the fish collection lamp according to the present invention is characterized in that a cooling fin is provided on the back surface of the main substrate on the side opposite to the light emitting diode module.

  Further, the fish lamp according to the present invention is characterized in that the main substrate provided with cooling fins constitutes a part of the waterproof case.

  The fish lamp according to the present invention is characterized in that the main substrate is formed in a plate shape, and the back surface of the main substrate on the side opposite to the light emitting diode module is in close contact with the waterproof case.

  The fish collection lamp according to the present invention is characterized in that the cooling fin is made of aluminum.

  Further, the fish collecting lamp according to the present invention is characterized in that the cooling fin is subjected to a corrosion resistance treatment.

  Further, the fish collection lamp according to the present invention is characterized in that the power supply unit is stored under the deck of the fishing boat when the fish collection lamp is mounted on the fishing boat.

  The fish collection lamp according to the present invention can obtain a necessary amount of light as a fish collection lamp without deteriorating the resilience of the fishing boat, and a fish collection lamp using a small and lightweight light emitting diode.

  Moreover, since the main board | substrate which provided the cooling fin comprises a part of waterproof case, the weight of the light source unit of a fish collection lamp can further be reduced.

Embodiment 1 FIG.
1 to 7 show the first embodiment, FIG. 1 is a configuration diagram of a fish collecting lamp 1, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is an exploded perspective view of a light emitting diode module 4. 4 is a cross-sectional view of a modified example of the light source unit 2, FIG. 5 is a cross-sectional view of another modified example of the light source unit 2, FIG. 6 is a diagram showing a fishing boat equipped with the fish collecting lamp 1, and FIG. It is the figure which compared the luminous intensity and weight at the time of using the conventional case-type LED (comparative example 1).

  As shown in FIG. 1, the fish lamp 1 includes a light source unit 2 and a power supply unit 3 that supplies power to the light source unit 2.

  In the light source unit 2, a plurality of light emitting diode modules 4 are mounted on a main substrate 5. In this example, a total of 30 light emitting diode modules 4 arranged in 3 rows and 10 columns are mounted on the main substrate 5. The arrangement of the light emitting diode modules 4 may be arbitrary, but the allowable temperature of the light emitting diode modules 4 is about 85 ° C., and any arrangement that does not exceed this temperature at the time of lighting may be used. The material of the main substrate 5 is a metal such as aluminum. The configurations of the light emitting diode module 4 and the main substrate 5 will be described later.

  The main substrate 5 on which the light emitting diode module 4 is mounted is accommodated in a waterproof case 6 made of stainless steel, for example. The portion of the waterproof case 6 that faces the light emitting diode module 4 is a light-transmitting cover (described later).

  The power supply unit 3 is electrically connected to the light source unit 2. The output of the generator of the fishing boat is AC 100-240V 50 / 60Hz. For example, the power supply unit 3 converts the AC output of the generator so that a direct current of about 350 mA flows through the light emitting diode module 4.

  As shown in FIG. 2, the light source unit 2 includes a main substrate 5 on which the light emitting diode module 4 is mounted in a waterproof case 6 having a light transmissive cover 6 a on a surface facing the light emitting diode module 4. . The light transmissive cover 6a is made of, for example, an acrylic resin.

  Cooling fins 5 a are integrally provided on the main substrate 5 on the back surface of the main substrate 5 on the side opposite to the light emitting diode module. However, it may not be integral. The material of the cooling fin 5a is the same as that of the main substrate 5, and is a metal such as aluminum. The cooling fins 5a are subjected to corrosion resistance treatment such as anodizing or painting.

  The main board 5 on which the light emitting diode module 4 is mounted is fixed to the waterproof case 6 with screws or the like.

  As shown in FIG. 3, the light emitting diode module 4 has three light emitting diodes 7 mounted on a substantially circular substrate 8 at substantially equal intervals in the circumferential direction. The number of the light emitting diodes 7 may be arbitrary. Then, the lead wire 9 is connected to the substrate. The substrate 8 on which the light emitting diode 7 is mounted is covered with a case 10 with a condensing lens having a condensing lens 10 a at each position facing the light emitting diode 7, thereby forming the light emitting diode module 4. In FIG. 3, since there are three light emitting diodes 7, three condensing lenses 10a are provided in the case 10 with condensing lenses.

  The present embodiment is characterized by the light-emitting diode module 4, and the light-emitting diode module 4 is dramatically improved in luminous intensity by combining the light-emitting diode 7 and the condenser lens 10a. Specifically, as shown in FIG. 7, the light intensity of the conventional bullet-type light emitting diode shown as Comparative Example 1 is about 2 cd, whereas the light emitting diode module 4 of Embodiment 1 has the light emitting diode 7 Even if only one lens is combined with the condenser lens 10a, the luminous intensity becomes 33 cd, and in the light emitting diode module 4, it becomes about 100 cd, which is three times as much. This corresponds to the luminous intensity of one light emitting diode module 4 and 50 of a conventional bullet-type light emitting diode.

  Since the light source unit 2 has 30 light emitting diode modules 4, the luminous intensity per light of the light source unit 2 is about 3000 cd, and the number of light emitting diodes 7 is 90 pieces. On the other hand, in the conventional bullet-type light emitting diode shown in Comparative Example 1, 1500 light emitting diodes are required to obtain the same luminous intensity as the light source unit 2 of the present embodiment.

  The weight of the light source unit 2 is also reduced to 1.5 kg in the light source unit 2 of the present embodiment compared to 3 kg in the first comparative example. Advantages of this embodiment when the light source unit 2 is mounted on a fishing boat will be described later.

  FIG. 4 is a cross-sectional view showing a modification of the light source unit 2. In the light source unit 2 shown in FIG. 4, the main substrate 5 does not have cooling fins. A lump-like (also plate-like) main substrate 5 is fixed so as to be in close contact with the waterproof case 6. Also in this case, the main board 5 is fixed to the waterproof case 6 with screws or the like. Other configurations are the same as those in FIG. Although the main substrate 5 does not have cooling fins, the main substrate 5 is in close contact with the waterproof case 6 made of stainless steel.

  FIG. 5 is a cross-sectional view showing another modification of the light source unit 2. In the light source unit 2 shown in FIG. 5, the main substrate 5 does not have a cooling fin. Moreover, the main board 5 is housed inside the waterproof case 6 via the support member 11. Also in this case, the main board 5 is fixed to the waterproof case 6 with screws or the like. Other configurations are the same as those in FIG. In this example, priority is given to simplifying the configuration over the heat dissipation characteristics.

  FIG. 6 is a view showing a fishing boat 20 on which the fish collecting lamp 1 is mounted. The 60 light source units 2 are suspended from a wire 20d passed to a support 20c installed on the front and rear of the fishing boat 20 on the deck 20a and the bridge 20b. The power supply unit 3 is housed under the deck 20 a of the fishing boat 20 and is electrically connected to each light source unit 2.

Generally, a ship is tilted due to the positional relationship between the center of gravity G of the ship and the center (buoyancy) B of the buoyancy that floats the ship, even if it is tilted to the left or right due to the action of waves or turning of the ship. The force that tries to restore the original state works, and this force is called restoring force. The intersection of the hull center line of a ship floating at a certain inclination angle θ and the buoyancy action line is called a transverse metacenter M. The magnitude S of the restoring force is determined by using the distance GZ (reconstruction lever) between the hull weight W and the buoyancy and gravity action lines.
S = W × GZ
Therefore, the greater the GZ, and thus the lower the center of gravity position, the greater the restoring force.

  From FIG. 7, the weight of the whole fish collection lamp on the deck 20a at a position higher than the bridge 20b on the deck 20a is 276 kg ((3 kg (light source unit weight) +1.6 kg (power supply unit weight))) × 60 lights in Comparative Example 1. 276 kg). In contrast, in the first embodiment, since the power supply unit 3 is housed under the deck 20a and the light source unit weight is half that of the first comparative example, 90 kg ((1.5 kg (light source unit weight) × 60 lights)) = Reduced to 90 kg). The first embodiment contributes to significantly lowering the center of gravity of the fishing boat by reducing the weight of the light source unit 2 to half that of the first comparative example and storing the power supply unit 3 under the deck 20a.

  The hull weight W is also proportional to the magnitude S of the restoring force. Although the hull weight W also decreases due to the decrease in the total fishlight weight in the present embodiment, the hull weight of a fishing boat equipped with the fishlight 1 is generally 9 to 20 tons, and the decrease in the total fishlight weight decreases the hull weight W. The ratio that affects is small.

Embodiment 2. FIG.
7 and 8 are diagrams showing the second embodiment, and FIG. 7 is a diagram comparing luminous intensity and weight when the light emitting diode module 4 is used and when a conventional bullet-type LED (Comparative Example 1) is used. FIG. 8 is a sectional view of the light source unit 2.

  In the light source unit 2 shown in FIG. 8, the light emitting diode module 4 is mounted, and the main substrate 5 having the cooling fins 5a constitutes a part of the waterproof case 6 (on the side of the anti-light transmissive cover 6a). Thereby, the weight of the light source unit 2 is further reduced.

  As shown in FIG. 7, the weight of the light source unit 2 is reduced to 1.2 kg as compared to 1.5 kg in the first embodiment. The weight of all the light source units 2 per fishing boat (total fishing light weight (on the deck) per fishing boat in FIG. 7) is reduced to 72 kg, compared with 90 kg in the first embodiment. The weight of all the fishing light lamps 1 per fishing boat (total weight of all the fishing light lamps per fishing boat in FIG. 7 (all)) is reduced to 168 kg as compared with 186 kg in the first embodiment.

  Therefore, if the fish collection lamp 1 using the light source unit 2 of the second embodiment is mounted on the fishing boat 20 in the same form as in the first embodiment, the center of gravity of the fishing boat 20 can be further lowered than in the first embodiment. And the resilience of the fishing boat 20 is increased.

FIG. 4 is a diagram showing the first embodiment and is an exploded perspective view of the light emitting diode module 4. FIG. 5 shows the first embodiment and is a cross-sectional view of a modification of the light source unit 2. FIG. 5 shows the first embodiment and is a cross-sectional view of another modification of the light source unit 2. FIG. 2 is a diagram showing the first embodiment and is a diagram showing a fishing boat on which a fish collecting lamp 1 is mounted. It is a figure which shows Embodiment 1, 2, and is the figure which compared the luminous intensity and weight at the time of using the light emitting diode module 4 and the conventional bullet-type LED (comparative example 1). FIG. 5 shows the second embodiment and is a cross-sectional view of the light source unit 2.
