Description

  The present invention relates to an underwater fishing lamp that collects fish by submerging in water such as the sea and emitting light.

  An underwater fishing light is a device that collects fish by sinking in the water such as the sea and emitting light. There are many fish species that have the property of gathering in light, and many fish gather in search of plankton that gather in light. For example, in the field of recreational fishing, dry-cell type underwater fish lamps are used.

  Conventionally, for example, a fluorescent lamp has been used as the light source of such an underwater fish collection lamp, but in recent years, an underwater fish collection lamp using LED illumination has begun to be proposed (for example, Patent Document 1).

  In order to collect seafood, the knowledge that the blue light emitted by the blue light emitting diode is effective is already known (for example, Patent Document 2). Further, according to the information collected by the inventors of the present application, there is information that the light of the blue light-emitting diode is effective for collecting small fish.

  However, since blue light is difficult to see with human eyes, it is expected that when an underwater fishing light with blue light emitting diodes is submerged, it is difficult to see the surrounding situation from the water. The

  This invention is made | formed in view of this point, and it aims at providing the underwater fish-collecting lamp with a large fish-collecting effect and high visibility of a surrounding condition.

In one embodiment of the present invention, a plurality of blue light-emitting diodes are arranged in a ring shape as an underwater fishing light that is submerged in water and collects fish by light. The first light source unit , the second light source unit in which a plurality of white light emitting diodes are arranged in a ring shape, and the light amounts of the first light source unit and the second light source unit are independently controlled. The first and second light source units so that the second light source unit is located above the first light source unit in a state where the underwater fish lamp is submerged. The control unit can control the light quantity of the blue light emitting diode of the first light source unit with 1 / f fluctuation and can be controlled independently for each group. And the control unit The light source unit emits light with a constant light amount, while the first light source unit controls the light amount of the blue light emitting diode so as to shift the fluctuation timing for each group with 1 / f fluctuation. A mode is provided.

  According to this aspect, the underwater fish collecting lamp includes a first light source unit made of a blue light-emitting diode and a second light source unit made of a white light-emitting diode. For this reason, small fish and the like are easily collected by the blue light emitted from the blue light emitting diode, and the white light emitted from the white light emitting diode also has a fish collecting effect. In addition, since the white light emitted from the white light emitting diode makes it easy to visually recognize the situation around the underwater fish collection lamp submerged from the water, it is possible to easily confirm the state of fish gathering from the water. In addition, since the light amounts of the first light source unit and the second light source unit can be controlled independently, the light amount of white light from the water is controlled while controlling the light amount of blue light so that fish easily gather. It is possible to perform control such that a sufficiently large value is set so that visibility is enhanced. Therefore, it is possible to realize an underwater fish collection light with a large fish collection effect and high visibility of the surrounding situation.

  ADVANTAGE OF THE INVENTION According to this invention, the fish collection effect is large, and the underwater fish collection lamp with the high visibility of the periphery condition is realizable.

  In Patent Document 2, a unit light source is configured by combining a blue-green light emitting diode and a white light emitting diode as an LED fishing light suitable for catching saury rods, and an electric rod is configured by combining a number of these unit light sources. ing. However, this is to combine different types of light emitting diodes to synthesize the color tone, thereby improving the suitability for different water quality or applications and reducing the eyes of fishermen's eyes. Therefore, the object, configuration and effect are different from the present invention. Furthermore, Patent Document 2 does not disclose anything about the feature that the light amounts of the blue-green light-emitting diode and the white light-emitting diode are independently controlled, and there is no need in the art.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an external view of an underwater fish lamp according to the embodiment. As shown in FIG. 1, a light emitting unit 2 is fixed to a main body unit 1 and is waterproof. A translucent cover 4 with 3 is provided around the light emitting unit 2. With the switch 5, the light emitting unit 2 can be turned on / off and the light emission mode at the time of turning on can be switched. A battery (not shown) is mounted inside the main body 1. The battery functions as a power source for the light emitting unit 2 and also serves as a weight when the underwater fish lamp is submerged.

  FIG. 2 is a cross-sectional view showing the internal structure of the underwater fish lamp shown in FIG. As shown in FIG. 2, a first light source unit 10 made of a blue light emitting diode 11 and a second light source unit 20 made of a white light emitting diode 21 are provided inside the light emitting unit 2. Here, as the blue light-emitting diode 11, a light wavelength peaking at 450 nm to 550 nm is used. FIG. 3A is a plan view of the first light source unit 10, and FIG. 3B is a plan view of the second light source unit 20. As shown in FIG. 3A, in the first light source unit 10, twelve blue light emitting diodes 11 are arranged in a ring shape, and each blue light emitting diode 11 emits light toward the outside of the ring. Irradiate. As shown in FIG. 3B, in the second light source unit 20, eight white light emitting diodes 21 are arranged in a ring shape, and each white light emitting diode 21 irradiates light toward the outside of the ring. . The first and second light source units 10 and 20 are arranged such that the second light source unit 20 is located above the first light source unit 10 in a state where the underwater fish collection lamp is submerged. This is because the visibility when viewed from the water is higher when the second light source unit 20 including the white light emitting diode 21 is located on the upper side, that is, the side closer to the water. Of course, the arrangement positions of the first and second light source units 10 and 20 may be interchanged.

  FIG. 4 is a circuit diagram showing a circuit configuration of the underwater fish lamp shown in FIG. As shown in FIG. 4, the twelve blue light emitting diodes 11 of the first light source unit 10 are divided into four groups of three, and the light quantity can be controlled independently. The eight white light emitting diodes 21 of the second light source unit 20 can control the light amount independently of the blue light emitting diodes 11 of the first light source unit 10. That is, the first current control unit 31 is provided for the blue light emitting diode 11 of the first light source unit 10, and the second current control unit is provided for the white light emitting diode 21 of the second light source unit 20. 32 is provided. The IC 30 can individually control the current flowing through the blue light emitting diode 11 for each of the four groups by giving a control signal to the first current control unit 31. The IC 30 can control the current flowing through the white light emitting diode 21 by giving a control signal to the second current control unit 32.

  In the present embodiment, the ON mode and the AUTO mode can be set by switching the switch 5. In the ON mode, the IC 30 causes both the first light source unit 10 and the second light source unit 20 to emit light with a constant light amount. In the AUTO mode, the IC 30 causes the second light source unit 20 to emit light with a constant light amount, while the first light source unit 10 controls the light amount of each blue light emitting diode 11 with 1 / f fluctuation. At this time, the timing of fluctuation may be shifted for each group. By controlling the amount of blue light with 1 / f fluctuation, it is possible to realize a light-emitting body that is closer to the natural world, so there is no sense of incongruity even when viewed from the eyes of the fish, and the fish collection effect is further enhanced. Conceivable.

  As described above, according to the present embodiment, the light amounts of the first light source unit 10 including the blue light-emitting diode 11 and the second light source unit 20 including the white light-emitting diode 21 can be independently controlled. For this reason, control is performed such that the amount of white light is set sufficiently large so that the visibility from the water is increased while controlling the amount of blue light so that fish easily gather with 1 / f fluctuation, for example. Is possible. Therefore, it is possible to realize an underwater fish collection light with a large fish collection effect and high visibility of the surrounding situation.

  In the present embodiment, in the AUTO mode, the amount of blue light of the first light source unit 10 is controlled with 1 / f fluctuation. However, the present invention is not limited to this. Such light quantity control may be performed. Further, the amount of white light of the second light source unit 20 may be varied by, for example, 1 / f fluctuation.

  In addition, the number of blue light emitting diodes 11, the number and grouping method of groups, the peak wavelength, and the number of white light emitting diodes 21 shown in the present embodiment are merely examples, and are not limited thereto. Further, the configurations of the first light source unit 10 and the second light source unit 20 are not limited to those shown here.

  In the present invention, an underwater fish collection light having a large fish collection effect and a high visibility of the surrounding situation can be realized, which is effective for leisure fishing, for example.
