Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a fishing light that is used by being thrown into the water together with a fishing net or fishing line. In particular, the present invention relates to a fishing light that is configured to include a built-in dry cell battery and emits light intermittently.

[Description of prior art]

In squid fishing and other fishing industries, a widely used method is to attach a fishing light to a fishing net or fishing line and throw it into the water to gather the catch for night fishing. This type of fishing lamp requires a certain level of brightness so that it can be recognized by the target prey, and depending on the type of fishing method, it may be necessary to throw a large number of fishing lamps into the water at the same time. For this reason, with conventional fishing lights, power cables are routed from each underwater fishing light to the fishing boat.
It was configured to supply power from a diesel generator inside the fishing boat. Therefore, it is necessary to install a powerful generator inside the fishing boat, and during operation, the generator consumes a large amount of heavy oil, resulting in high operating costs.

Furthermore, such fishing lights require a power cable to be inserted into the water along with the fishing net or rope, which is a complicated operation and is prone to cable breakage.
This causes high costs and increased work man-hours.

Conventionally, devices have been known in which batteries are housed inside each fishing light to light the lamps, but batteries become expensive for fishing methods that require a large number of fishing lights at once as described above. In addition, it is not economically viable because it requires a large amount of man-hours to replace the battery.

Furthermore, there are fishing lights that flash their lamps to save power, but conventional fishing lights of this type use the heat generated by the lamp to automatically open and close a bimetallic switch, which limits the lighting cycle. The lighting time rate within is only a fraction of the time.
That's all. Furthermore, since these flashing fish-collecting lights utilize heat generation, they often break down, and in fishing methods that use multiple fish-collecting lights at the same time as mentioned above, it becomes necessary to frequently repair or replace them. It cannot be used practically.

Furthermore, there has been a known technology in which the transparent part of the container through which the light rays of the luminescent material pass through is provided with unevenness to make the light appear to be scattered, but tests have shown that this does not work effectively underwater. Against this background, the inventor attempted to develop a fishing light that is economical, has few failures, and can efficiently collect prey, and conducted numerous tests and developed the present invention. I was able to complete the song.

[Purpose of the invention]

The objectives of the present invention are: ■ Low power consumption; ■ Small man-hours required to operate fish gathering lights even in a fishing method that uses a large number of fish gathering lights at the same time; ■ Low operating costs; ■ Requires operation on board or on site. Our goal is to provide a fish-gathering light that does not cause problems, ■ does not have any malfunctions, and ■ is highly effective in attracting prey.

[Features of the invention]

The present invention uses a dry cell battery as a power source, and a water pressure resistant plastic closed container having at least a transparent part and including a dry cell storage chamber as the container.

Also, a light emitting diode is used as an electroluminescent body. The electric circuit connecting the battery terminal arranged in the dry cell storage chamber and this electroluminescent body includes an oscillation circuit that repeatedly sends out an output signal every first time ('r1), and an output of this oscillation circuit. The above first time (
Tz), a very short second time (
Only T2) is characterized in that it includes circuit means for electrically connecting the battery terminal and the light emitting diode.

Furthermore, in addition to the first invention, a second invention provides that, in the transparent portion of the water-pressure resistant plastic sealed container where the light emitting diode is arranged, irregularities of transparent plastic are formed on the inside of the container. It is characterized by:

Further, the first time (T1) is set in a range of 0.3 to 3 seconds, and the ratio of the second time (T2) to the first time (T1) is 1/300 to 1/3000. It is preferable to set it within the range of .

Preferably, the electric circuit comprises one hybrid integrated circuit including a semiconductor switch circuit and one external capacitor that determines the first time.

The shape of the unevenness is preferably a plurality of step-like unevenness.

A fishing light with 11 1il light-emitting lights is suitable for pole-and-line fishing.

Fishing lights equipped with multiple light emitting diodes are suitable for large-scale fishing methods in which they are attached to fishing nets.

[Explanation based on examples]

FIG. 1 is a diagram showing the external appearance of a device according to a first embodiment of the present invention. FIG. 2 is a cross-sectional structural diagram thereof.

The water pressure resistant plastic airtight container includes an upper container 1 formed by a colored plastic mold, a lower container 2 formed by a transparent plastic mold, and one metal ring 3 and two synthetic rubber O-rings. 4.

In this embodiment, two JIS standard UM-5 type dry batteries are connected in series and housed in this dry cell storage chamber. - A metal fitting 6 is embedded in the outer upper end of the L-portion container l, and this metal fitting 6 is used to attach the fish-collecting light to a fishing net, a rope, or the like.

This water pressure resistant plastic sealed container is 45 kg/c
The needle was designed so that there would be no water leakage even if J pressure was applied.

Therefore, this fishing light can be used up to a depth of 450 m.

A roughly cylindrical electric circuit 7 is fitted inside the lower container 2, and a battery terminal 8 is provided on the upper plane of the electric circuit 7.
is provided, and a light emitting diode 9 is attached to the lower plane.

The battery terminal 8 becomes the positive terminal of the dry cell battery 11 in the dry cell storage chamber. A negative battery terminal 12 is arranged in the upper part of this dry cell storage chamber, and its potential is determined by a conductive plate provided along the inner wall recess of the upper container l. 3 leads to an electrical circuit 7. More specifically, this conductive plate 13 is connected to a metal ring 14 provided on the lower end surface of the upper container l,
When the upper container 1 is screwed into the lower container 2, the metal ring 14 is configured to come into contact with an electrode provided on the upper end surface of the electric circuit 7. Therefore, when the screw connection between the upper container 1 and the lower container 2 is slightly loosened, the metal ring 14 separates from the electric circuit 7 and the switch is turned off.

A mounting hole 10 is formed at the lower end of the lower container 2. The mounting hole 10 is used together with the metal fitting 6 to attach the fishing light midway along a fishing line when the fishing light is used for pole-and-line fishing. The metal fitting 6 has a rotatable tip and absorbs the weight of the fishing line or fishing net wire.

One of the important features of the invention is the use of light emitting diodes as the electroluminescent material. Light emitting diodes are more robust and have a longer lifespan than incandescent lamps.

It also has high light conversion efficiency and low heat generation.

Furthermore, one of the important features of the present invention is that this electric circuit 7
It is in.

FIG. 3 is a block diagram of the electric circuit of the apparatus according to the embodiment of the present invention. A negative terminal 12 of the battery 11 passes through the electric circuit 7 and is connected to one end of the light emitting diode 9. A positive terminal 8 of the battery 11 is connected to the other end of the light emitting diode 9 via a collector circuit of a transistor 16 inside the electric circuit 7 . Inside this electric circuit 7, a battery terminal 8 is provided.
CR oscillation circuit 1 driven using the power supplies of
7 and a flip-flop 18 as well. The CR oscillation circuit is an oscillation circuit that oscillates at a period of a first time (T1).

In this example, time T1 is approximately 0.8 seconds. The output signal is connected to the set input signal S of the flip-flop 18, and is also branched and connected to the input signal R of the flip-flop 18 via a delay circuit 19. The delay time (T2) of this delay circuit 19 is approximately 1.2 milliseconds. The output Q of this flip-flop 18 is connected to the control electrode of transistor I6. A capacitor 20 is connected to the CR oscillation circuit 17, and this capacitor 20
It is configured to determine the oscillation period (T1) of the R oscillation circuit 17.

CR oscillation circuit 17, delay circuit 19, flip-flop 1
8 and the transistor 16 are formed in a hybrid integrated circuit of lI[l, and the capacitor 20 is attached externally to this hybrid integrated circuit.

To explain the operation of the device configured in this way, the battery 1
1 is mounted inside the upper container 1, and the upper container 1 and the lower container 2 are joined together. When power is supplied to the electric circuit 7,
The CR oscillation circuit 17 oscillates at a period of approximately 0.8 seconds. CR
When the output signal is sent from the oscillation circuit 17, the flip-flop 18 is set, and about 1.2 milliseconds later, a signal is sent from the delay circuit 19, and the flip-flop 18 is set.
is reset.

Accordingly, transistor 16 operates approximately 1.8 seconds every approximately 0.8 seconds.
The light emitting diode 9 is turned on by conducting for 2 milliseconds.

Furthermore, one of the features of the present invention is that the inner wall surface of the transparent lower container 2 is formed with irregularities. In this embodiment, the unevenness is formed into a large number of step-like unevenness in a so-called diamond cut shape.

In the conventional structure, these irregularities were formed on the outer surface of the container. With this conventional structure, when the fishing light is in the air, light is scattered, but when the fishing light is placed in the water, the light is scattered because the ratio of the optical refractive index of transparent plastic and water is approximately 1. Light is no longer scattered. Since the present invention forms these irregularities on the inner wall surface, light is sufficiently scattered even when the fishing light is put into the water.

When the device configured as described above was attached to a fishing net and tested, it was found that 1. I liked that the prey often gathered there. In particular, the lighting time rate T
It was found that even if 2/Ts was chosen to be smaller than 1/l 000, other prey of "squid"-1 were often attracted. In addition, the optimal values for the lighting period and lighting time rate differ depending on the type of target prey, and by changing the lighting cycle and lighting time rate, it is possible to distinguish the type of target prey. Understood.

It has also been found that the reaction of the prey changes when the color of the light emitting diode 9, the color of the plastic support holding the light emitting diode 9, or the color of the transparent plastic of the lower container 2 is selected. Therefore, these colors can also be selected depending on the prey.

In this way, by setting the lighting time rate to be extremely small, power consumption can be significantly reduced. In this embodiment, the total average power consumption including the oscillation circuit is about 3.0 mA, and can be operated continuously for about 6 months using two small UM-5 type batteries.

If alkaline batteries are used, continuous operation can be achieved for even longer periods of time.

The instantaneous power at the time of lighting is about 0.06W.

As for the lighting time ratio (T2/T1), the smaller it is, the more effective it is for economical power consumption, but it is impossible to make the lighting time T2 shorter than the rise time of the light emitting diode. When the lighting time rate is increased, the effect of economicalizing power consumption is lost. As a result of a test, it was found that the lighting time rate is suitably 1/30 to 1/3000, and particularly preferably set to 1/300 to 1/3000.

FIG. 4 is a structural diagram of an apparatus according to a second embodiment of the present invention.

In this embodiment, four light emitting diodes 9 are mounted inside the transparent lower container 2, and the circuits of the light emitting diodes 9 are connected in parallel by a metal wire 22, so that the four light emitting diodes 9 blink at the same time. It is structured as follows. The configuration of the electric circuit 7 is the same as that of the first embodiment, but the batteries 11 are of the JIS standard UM-2 type, and the overall size is larger than that of the first embodiment. It is composed of This fishing light is attached to a fishing net and is suitable for large-scale fishing.

The device of this second embodiment also has irregularities formed inside the lower container 2, so that light is effectively scattered in the water.

This device can also collect prey extremely efficiently,
It operates continuously for more than six months, and does not require any battery replacement or other maintenance work during this period.

As mentioned above, the apparatus of the present invention has an upper container 1 and a lower container 2.
If you loosen the screw between the two, the power supply to the electric circuit 7 will be cut off and the operation will stop. Even if you load the fishing light and pull it into the hold, it is not necessarily necessary to stop its operation every time. The battery will discharge naturally even when the device is in rest mode. Since the fishing light of the present invention consumes very little power, there is no problem even if it is operated continuously for several months. It is also possible to ship the product in an operating state from the time of shipment.

The fishing light of the present invention has no consumable parts other than the battery, and the electric circuit is integrated into a hybrid integrated circuit, so it is resistant to vibrations, and this fishing light is extremely stable and has almost no failures. .

Furthermore, since a light emitting diode is used as the electroluminescent body, there is no heat generation during operation.

The reason why such a small lighting time rate is effective against prey is thought to be because the prey's eyes have considerable afterglow.

A light emitting diode with a large afterglow characteristic can also be used.

The electric circuit can be configured in various ways other than those shown in the above example.

The number of light emitting diodes is not limited to one or four as in the above example, but a plurality of light emitting diodes may be used and configured to be connected in parallel or in series.

The fishing light of the present invention is suitable for simultaneous use in large numbers as described above, but can also be used for pole-and-line fishing or hobby fishing.

(Description of Effects) As explained above, according to the present invention, power consumption is extremely low, and even in large-scale fishing methods that use a large number of fishing lights at the same time, the number of man-hours required to operate the fishing lights is small.
You can obtain a fishing light that is highly effective at attracting prey. Battery replacement and maintenance only need to be done once every few months. Therefore, there is no need to replace batteries on board the ship, and batteries can be replaced using cheap labor when the ship returns to port.

The fishing light of the present invention has significantly lower operating costs than conventional products, saves fuel and labor costs, and is almost free from failure.

Furthermore, when using the fishing light of the present invention for pole-and-line fishing or fishing as a hobby, there is no need to perform any operations such as starting and stopping the fishing light or replacing batteries on the spot, and there is no need to perform any operations such as starting and stopping the fishing light or replacing batteries. It operates extremely stably without any foreign matter getting into it. Moreover, it is highly effective in attracting prey.
