Conventionally, when a light collecting light installed on a fishing boat such as a squid fishing boat is turned on at night, the fish catches squid and fish using the habit of gathering fish near the hull, illuminating the water surface on both sides of the hull.

[0003] In recent years, in order to reduce the fuel consumption of fishing boats and reduce light attenuation in water, a fishing light using a light emitting diode as a light source has been proposed (for example, see Patent Document 1).

FIG. 15 is a diagram showing an example of a fish collecting lamp using a blue light emitting diode as a light source. In this case, the fish collection lamp 500 uses the light emitting diode 501 as a light source. A plurality of blue light emitting diodes are arranged in a matrix on the substrate 502 to form an LED surface light source. The fishlight 500 is installed to hang on the ship.

The load on the mechanism can be reduced. In the case of squid fishing, squid eyes have a relatively high sensitivity to blue light, and therefore it is more effective to collect fish with a light source of a blue or green light emitting diode.

Further, pivotable joints are provided at both ends of the fishlight 100, so that the irradiation angle of the fishlight 100 can be adjusted within a predetermined angle range. Here, as the angle adjusting means, a mechanism using a manual method can be considered. For example, rotate the joint 80a or 80b with a rotation stop screw (not shown), adjust the illumination angle by hand, and fix it with the rotation stop screw.

In the above-described embodiment, the supporting means 20 is a force using a pipe-shaped member having one hollow structure, but is not limited to this. For example, wiring board 1

It should be composed of two parts: a board mounting member to which 2 is attached and a pipe-shaped member having a hollow structure.

[0082] Further, in the fish collecting lamp devices 101 and 200 of the above-described embodiment, the force for adjusting the irradiation angle using the rotation mechanism 60 and the motor 70 is not limited to this. Instead of the rotation mechanism 60 and the motor 70, other means for adjusting the irradiation angle may be used. For example, the irradiation angle is adjusted by a manual method. In the case of the manual method, the rotation mechanism 60 and the motor 70 are not necessary, and a rotation stop screw is provided on the bearing 50, the irradiation angle is adjusted by hand, and the rotation is fixed with the rotation stop screw. In this case, the mechanism can be simplified and the cost can be reduced.
