Abstract

According to the present invention, an underwater LED-fishing lamp for trolling for a hairtail comprises: a driving frame which has a narrow front side and a wide rear side, has an opening formed in a rear surface, and includes an LED light-emitting device installed therein; a battery accommodation frame which has an opening formed in a front surface thereof, is connected to the opening of the driving frame, and accommodate a battery supplying power to an LED light source; and a water-proof rubber ring which is installed at a fixing portion of the driving frame and the battery accommodation frame. Since light is emitted from the LED light source, energy efficiency is excellent compared to an existing metal halide lamp (MHL) used as a fishing lamp. Since light is emitted at a direction of 180, luring effect of a fish can be improved without increasing brightness of a fishing lamp. Since a body frame of the fishing frame has a narrow front side and a wide rear side and a wing is installed on an edge of the body frame to improve momentum and minimize a resistance to a fluid speed, the fishing frame is moved only in one direction even at an ocean current wave, thereby improving luring efficiency.

Description

{LED-Fishing Lamp for hairtails trolling}

[0001] The present invention relates to an underwater pick-up lamp for collecting fish in a catching artifact, and more particularly to a structure in which a driving frame and a battery receiving frame which form a main body are structured with a neck- The LED light source device is formed by mounting an LED light source on one side of the PCB, and the PCB connected to at least one of the PCBs is formed at an angle of 120 ° so that the light of the mounted LED can be radiated in the 180 ° direction. The present invention relates to an LED underwater pick-up lamp for fishing.

Trichinus lepturus ) is a relatively remote fish species, which is mixed with sand and mud at depths of 100 m. It emerges in a shallow place during the early summer season and floats to the surface at night. Because the tail fin is absent and the tip is thin like a thread, the vertical movement is rather severe than the horizontal movement. Therefore, they are caught and picked up in the shipyard at Yeonjanghae Station in Jeju Island.

Shrimp fishing has been carried out by fishing tackle, which is one of the most representative fisheries of Korea in the coastal waters of Korea. The fishing cost of fishing is very closely related to the oil price, but it is believed that increasing the brightness of the fishing tackle can increase the catch because the catch is well absorbed and the excessive competition of the light source output is intensified and the coast fishing tackle fishing boat less than 10 tons This is because the ratio of oil consumption is so large that the fuel cost accounts for 10-20% of the catch using excessive power of 60kW.

In addition, fishing vessels have a labor-intensive fishing structure consisting of four or more skilled fishing vessels per 5-ton fishing vessel, and the number of seafarers is very high due to avoidance of boarding, Technological development is being carried out as technology-intensive pickle fishery rather than fishing.

It is a fishing method that catches artificial bait and sheds an object mainly by using a fishing boat for a fish that swims with a flock. The artificial bait moves while dragging in the water, so it causes a catching effect. On the other hand, The water depth is adjusted by the table, middle, and low layer according to the swimming layer of For the purpose of catching fish species with daylight, the artificial bait is replaced or added to a pickle.

In the case of Japanese pickle fishery, it is automated by making it possible to operate a single fishery, and it is operated by attaching an incandescent light bulb and an LED (light-emitting diode)

On the other hand, the characteristics of the fishery industry using light pick-ups are largely trapped in a short time by controlling the behavior of the target fish species with light, and there is hardly a comprehensive study on the behavior of fish species according to the light environment. Plankton, etc. are collected first, followed by a fish or quasi-fish, and then a photoreactive behavior habit of fishes, such as squid and salmon, gathering.

Starting from the petroleum and acetylene lights, electric lights were applied from the 1930s. In the early stage, light metal incandescent lamps (MHL) picked up in the late 70s, such as low-capacity incandescent lamps and 60s halogen lamps. Currently, 1.5kW metal halide lamps (MHL) are the mainstream.

However, in recent years, the increase in oil prices and labor costs has caused excessive light source consumption to be imposed on fishery management, and metal halide lighting, which is mostly used as a pick-up lamp, has been found to have a bad influence on the human body. LED pick-up lamps are attracting attention as a light source for safe pick-up lamps.

However, in the case of an LED headlight used in water, the headlight body may be damaged due to contact with water, and the headlight body may be damaged due to the resistance of the water and the external force due to the current due to the moving speed of the hull in water. In addition, since the light emitted from the pick-up is not transmitted to the water as it is, it is refracted according to the sea surface reflection according to the seawater condition, the night and day, the depth of the water depth and the turbidity, and therefore the light source can be sprayed more diagonally. It is necessary to develop a spearhead with excellent durability.

In Korean Patent No. 10-1396061, the shape of a convex lens used to improve the efficiency of a light source is modified to a donut shape in which the center is depressed and both side portions are convex, so that the light concentrated in the center of the center is diffused in a wide circle shape And a core including a heat pipe that is directly attached to a PCB substrate to generate heat and capable of discharging heat, and a plurality of heat sinks are coupled to a circumferential surface of the core. Korean Patent No. 10-0673377 discloses a fish-eye lens having a camera coupling unit that combines a plurality of cameras and an illumination light to the lower side of a fish-eye socket, and a fish-eye catcher that attracts fish by illumination is constructed. A type of fish and a fish amount can be identified by a user on the ship, and thus, a camera capable of providing convenience of operation by improving the function of a fishing rod is disclosed. Korean Patent No. 10-1432089 discloses an LED underwater pick-up lamp and an illuminating lamp for increasing the underwater light amount by directly projecting light in water so as to increase the efficiency of catching fishes such as squid, (Envelope-like structure), which is provided on the side of the light emitting surface, and a back cover which forms a rear end portion of the housing, a fastening mechanism for sealing the edges of the two covers, The inside of which is filled with a liquid insulating light transmitting material to constitute a flexible enclosure which has a liquid heat radiation effect and a waterproof effect even under various pressure conditions of water and water, The present invention relates to an LED underwater lighting / The. In Korean Patent No. 10-1367883, light having directivity is irradiated to the water surface W from the light source 1 to collect fish. A deep incidence region B is formed where the depth of incidence of the light into the water is farther than the fish F formed by the collected fishes. And a picking method and a picking system in which a deep incidence region B is moved in the direction of the light source 1 to guide the fish group F toward the light source 1. However, the above-mentioned prior art document discloses a driving frame in which an LED light source is irradiated at an emission angle of 180 degrees with an opening formed at the rear side of the light guide structure of the present invention. A battery receiving frame for receiving a battery which is opened in a front portion and fixed inside the opening of the driving frame and supplies power to the LED light source; The structure including the driving frame and the waterproof rubber ring provided at the fixing portion of the battery housing frame is not disclosed and shows a difference.

In order to solve the above-mentioned problem that the LED light source and the LED light source spray angle are very narrow due to the resistance of water generated according to the speed of the tug line when the LED light source is applied to the pull fishing method, The driving frame and the battery receiving frame are structured as a chrome backlight, and wings are installed around the side surface. The LED light source emitting the LED light source includes an LED light source on one side of the PCB, one or more PCBs connected to one another, and the angle between the connected PCBs is 120 ° so that the LED light source has 180 ° And to provide an LED underwater pick-up lamp for a catching fish for LED light source to be emitted.

As a means for solving the above problems, the present invention provides a driving frame in which a rear side of an opening is formed in the shape of a forward-rearward light, and an LED light source radiating device is installed therein; A battery receiving frame which is formed with an opening in a front portion thereof and is connected to and fixed to an opening of the driving frame and accommodates a battery for supplying electric power to the LED light source; And a waterproof rubber ring provided at a fixed position of the driving frame and the battery receiving frame.

Since the LED headlight for salting-forking fishing according to the present invention is radiated as an LED light source, it is more energy efficient than metal helide (MHL) used as a conventional light source for a headlight, and a light source can be emitted in a 180-degree direction, It is possible not only to increase the efficiency of collecting fish but also to increase the propulsive force and to minimize the resistance of the flow velocity by installing the wings on the perimeter of the structure of the main body of the fishing rod, So that it can stably and unidirectionally move without any movement such as rotation.

1. Experimental tank and LED light source installation

Fish behavior tests were conducted in the large water tank of the Institute of Yangshu Fishery Research Institute between November and December 2015, and the water temperature during the experiment was 16.5 ~ 19.5 ℃. The experimental group consisted of 136 fishes caught in the vicinity of Seongsanpo, Jeju - do, and 4 ~ 8 healthy fish were used for the experiment. The size of the experimental fishes was 68.9 ㎝ (SD 9.2 cm) And an average weight of 135.9 g (SD 47.9 g).

Fig. 1 shows a water-circulated circular water tank in which the present experimental example is implemented. The experimental tank (Ⅰ) and the adaptation tank (Ⅱ), each of which had a diameter of 15 m and a height of 1.7 m, were installed in the water tank, and the water depth of the water was maintained at 1.5 m. In the tank, the light was completely blocked, maintaining the dark state.

The LED light source (ⓐ) of blue, white, green, and red is installed so that light is transmitted downward from the edge of the water tank which is 70 cm on the surface of the water. The wavelength ranges of 430 to 460 nm for blue light, 500 to 570 nm for green light, 650 to 680 nm for red light and 400 to 700 nm for white light were used as wavelength ranges for the LED light sources used in the experiment. The brightness of the illuminated area on the water surface was 10.5 ~ 15.0 lux for blue light, 33.0 lux for green light, 10.9 lux for red light, and 24.7 lux for white light.

The LED light source was installed at 0.5 ~ 1.5W, and the size of the illumination area (3) was adjusted by attaching a LED filter and a funnel-shaped cap (2). The divergence angle was narrowed to divide into a lighting zone and a non-lighting zone in the tank, and the size of the lighting zone was 1.1 m in diameter. In order to observe the behavior of the experimental fishes in the dark room, we installed a special observation camera (ⓑ) for the ultra low light which is connected to the computer (ⓒ) which can be remotely controlled.

2. Checking effect of LED light source

1) The effect of picking LED light source

The confirmation of the picking effect of the LED light source was made by measuring the time that the LED light source was turned on to react to the light source. FIG. 2 shows the behavioral response of the hairtail to the lighting of the LED light source. At the same time as the LED light was turned on, the distribution of the hairtail in the water tank was distributed uniformly in the wall and the whole area of the tank, The behavior of the haircuts for the LED light was normally perpendicular to the surface of the water, and when the LED light was lit, it began to gather toward the light source within 10 to 60 seconds.

When the two light sources were lit at the same time, the behavior of the hairtails responding to the light was slightly different depending on the relative light source. The behavior patterns of blue light when blue light and red light were simultaneously lit were classified into three types. Gathering into the lighting zone under the light source and continuing to stay vertically, gathering in the lighting zone and continuing to stay horizontally in the lighting zone around the water wall, and gathering in the lighting zone and coming out of the lighting zone and lighting zone There was a repetitive action to go. Particularly, the residence time was longer in the surrounding area than the lighting area, which is the boundary of the lighting area.

The behavior patterns of blue light when blue light and green light were on can be roughly divided into three types. Move horizontally to a lighting zone below the light source, continue to stay vertically, move out of the lighting zone, move horizontally to the lighting zone, continue to stay horizontally in the lighting zone and exit out of the lighting zone, There was an act of moving to the green lighting area after staying together. Retention time was longer in the blue light source area than in the green light source area.

2) LED color light judgment according to the effect of picking up LED light source

In order to confirm the optimal LED color light according to the picking effect of the LED light source, two kinds of color lights were compared at the same time, and a color of the dominant reaction rate was compared with other color lights. That is, the combinations of light sources were blue and red, blue and green, blue and white.

The experimental fish were placed in the experimental tank and the two kinds of LED lights were lighted at the same time in dark condition. The frequency of the emergent hairs in each lighting zone was counted for 5 minutes. Respectively. The above-mentioned five-minute observation time is a predicted time for a hind leg to react to a pick-up of a fishing catch in the field.

In the light source combination experiment, the light source position was changed 10 times a day twice in the morning and evening, and three researchers simultaneously surveyed the behavior of the hawk with the camera. On the other hand, t-test was performed on the reaction result for LED color light source, and the significance was verified.

FIG. 3 shows the reaction rate of the haircut according to the combination of the LED light sources, and FIG. 4 shows the relative reaction rates of the LED light sources with respect to the blue light. In blue light and red light, 97% and 3% (p <0.001), respectively, showed a large difference in response to the two light sources. The response rates of blue light and green light were 75% and 25% (p <0.001) and those of blue light and white light were 67% and 33% (p <0.001), respectively. As shown in FIG. 4, the response rate of each color light to blue light was 50.1% for white light, 33.3% for green light, and 3.1% for red light.

The reaction rate of the hairtail to color was highest in blue light, followed by white light, green light and red light. As a result, the blue light and the green light were superior to the underwater penetration characteristics of seawater and were determined to be a pick - up light source which has a high effect of collecting fish.

3) Confirm the effect of picking up LED light source

Based on the above experimental results, we divided the narrow area (0.4 m in diameter) and the large area (1.5 m in diameter) to compare the effect of the illumination area width (light source divergence angle) The frequency of emerging hawks was counted.

Figure 5 shows the response rate of a hawk in a narrow illumination area and a large illumination area in a blue LED light source. In the blue LED light source, the response rate of the hair clip was 36% in the narrow illumination area and 64% in the wide illumination area (p <0.01).

The difference of the response rate was 3.8 times higher than the illumination width of 3.8 times, which was not so high. However, there was a difference in the response rate depending on the difference of the lighting zones. do.

3. Grass For fishing  Design of LED light source

Based on the results of the behavior of the fish in the experimental tank, we designed the LED underwater pick - up lamp for catching catch. The detailed configuration will be described in detail with reference to the accompanying drawings.

Fig. 6 shows a perspective view of the LED underwater pick-up lamp for a turf picking fish of the present invention. A driving frame (10) having a structure in which the LED fish catching lamp for catching fish for catching fish has a structure of a chopper backlight, an opening is formed in a rear side thereof, and an LED light source radiating device is installed therein; A battery receiving frame (50) formed with an opening in a front portion thereof and connected to the opening of the driving frame, the battery receiving frame (50) accommodating a battery (51) for supplying power to the LED light source; And a waterproof rubber ring 60 provided at a fixed position of the driving frame and the battery receiving frame.

Since the driving frame and the battery receiving frame are made of polycarbonate, the base material is excellent in impact resistance, heat resistance, weather resistance, and the like, so that when the battery is stocked in water, the body is prevented from being broken by the flow of the flow . In addition, even when stored in seawater for a long period of time, there is almost no deformation, and the material is transparent, so that the LED light source can be easily transmitted through the water.

A blade 70 having a tapered structure configured to be similar to an airplane wing is installed around the driving frame and the battery accommodating frame to generate a lift force due to the difference in the flow velocity between the upper and lower portions to increase the thrust, There is an effect. Therefore, even if the water flows in the multi-directional water, the body can be stably moved in one direction continuously without losing propulsion force, and the fish can be collected in a small area with high density, which is easy to catch.

Fig. 7 shows a side cut-away view of the LED underwater pick-up lamp for the catching-fishing of the present invention. The driving frame 10 has an all-optical structure in which the front portion is narrow and its periphery is widened toward the rear portion. The corner portion is formed in a round curve shape with rounding treatment. On the side of the front portion, A corrugated pipe connecting hole 11 is formed which can be connected and fixed.

When the hull connected to the underwater pick-up lamp moves, the underwater pick-up lamp receives the resistance of water according to the moving speed. The drive frame structure of the present invention minimizes the resistance of the water to improve the durability of the main body, There is an effect that it is easy to arrange the garment as appropriate.

In the inside of the drive frame, an LED radiating device 12 for radiating an LED light source is provided. In general, an LED is a device in which electrons and holes meet at a PN junction due to current application and emit light. In general, the LED is configured by a package structure in which an LED chip is mounted. A printed circuit board (PCB) 12b and one or more LED light sources 12a mounted on one side of the PCB.

The PCB 12b of the present invention has a plate structure formed of a metal or a ceramic material, and the ends of the other PCB are connected to the ends of the single PCB. In one embodiment shown in FIG. 8, a single PCB is installed in the horizontal direction, and terminals of the other PCB units are connected to the distal end of the PCB.

At this time, the angle between the connected PCBs is most preferably 120 °, and the angle between the LEDs is an optimal angle so that the LED light source can be emitted in the 180 ° direction. The PCB effectively contacts the LED chips to transfer heat generated from the chip to the outside. The LED light source 12a of the present invention is a conventional LED (Light Emitting Diode), has a very long life, is environmentally friendly, and has a low power consumption. As shown in FIG. 9 of the present invention, the emission wavelength of the LED light source is based on blue light in the range of 450 nm to 480 nm.

The base emission wavelength is a wavelength most favorable for the transmission characteristic of the catching of the hatchlings and optimal for the visibility as well as the wavelength favorable for catching the hatchlings. In addition, since LED light sources of other wavelengths can be additionally installed, the earlobe of the present invention can be suitably applied not only to captive species but also to other types of fishing.

In the LED radiator, a heat sink 13 is provided on the other side of the surface on which the LED light source is mounted. Since the light emitted from the LED light source is directional, the LED is directly heated to increase the light intensity in order to improve the water transmittance. Therefore, the amount of heat generated per unit area is large and the LED is greatly influenced by the light efficiency and lifetime depending on the temperature. the heat generated from the LED light source must be released to the outside by installing the heat sink.

A connection PCB 14 is provided on a side of the LED light source radiating device and the battery 51. The connecting PCB can install the FR4 PCB to effectively dissipate the heat generated from the LED, thereby preventing heat from being transferred to the battery.

The battery housing frame 50 is formed in a structure in which an opening is formed in a front portion and an opening is fixed to an opening of a rear side of the driving portion frame to seal the inside. A waterproof rubber ring (60) is provided on the fixing surfaces of the battery housing frame and the driving unit frame to prevent water from entering the interior of the battery housing frame and the driving frame.

The battery accommodating frame is provided with a battery 51 capable of supplying power to the LED light source radiating device. A spring 52 is provided on the inner side of the battery accommodating frame so as to correspond to the rear side of the battery, It mitigates the applied force and stabilizes it.

As described above, according to the present invention, the blue light source of 450nm-480nm wavelength and other kinds of wavelengths were irradiated to the hairtail through the fish behavior test, and the effect of the salting out of the hairtail, reaction time and reaction rate according to the angle of diffraction were examined. As a result, the response rate of the hair clippers to color light was highest in blue light, followed by white light, green light and red light in the order of blue, green, and blue. In the illuminated area, the reaction rate was 64%. Therefore, it was confirmed that blue light and green light are superior to underwater penetration characteristics of seawater and that it is a pick-up light source having a high effect of collecting fish. Based on this, it is possible to radiate light in a direction of 180 ° according to the combination of radiation angles of light sources By this design, when the present invention is used as an underwater pick-up, it is possible to increase the efficiency of harvesting the hawk and increase the catch rate.

The inventive LED underwater pick-up lamp is more energy efficient than metal helide (MHL), which is used as a conventional light source for a headlight because it is emitted as an LED light source, and the light source can be emitted in a 180 ° direction, It is possible to improve the efficiency of collecting fish without increasing the number of fishes, and it is possible to promote the industrial development of the fishery industry which is more technology-intensive than the existing labor-intensive fishing, It is possible to use it industrially.
