Description

Fish luring lamp system

The present invention relates to a pick-up system, and more particularly, to a pick-up system using a light emitting diode.

In order to effectively catch squid and cutlass, fishes which collect target species are generally used.

Currently, the oil cost of generators used to light up the fishing boats of fishing boats for fishing fishing accounts for more than 60% of the total oil costs for fishing, and the replacement cost of fishing boats accounts for more than 40% of the total fishing cost. It is a big burden. In addition, in recent years, the high oil prices are causing huge obstacles to fishery management.

Metal halide lamps are mostly used as squid picking lamps.

However, metal halide lamps usually consume about 1KW to 3KW, which means that they consume a lot of power, and there is a risk of burns to fire or workers due to the high temperature of the glass surface during light emission, and short lifespan of about 3,000 hours. Holding it. In addition, metal halide lamps need to be replaced due to poor performance when they are used for about 4 to 5 months, and the additional weight required for lighting increases due to the heavy weight and bulky ballasts. There is also a disadvantage that the fish tank volume for storing the fish is reduced.

In addition, since the light of the metal halide lamp is radiated in all directions of the space through the glass sphere, 60% to 70% or more of the total amount of light is unnecessarily consumed in the sky and the deck, which are areas other than the irradiation range required for picking up, and the metal halide Since the light emitted from the lamp is generated from the infrared region to the light of some ultraviolet region, light of the wavelength band other than the wavelength band that is effective for catching fish, for example, squid, is emitted. There is also a disadvantage falling significantly.

On the other hand, since blue light is effective for picking up squid and the depth of penetration in seawater is longer than other wavelengths, some of the blue light are attempted to emit light of blue wavelength, but worker fatigue is increased compared to white light. There is a disadvantage in reducing the operating efficiency.

The present invention has been made to improve the above problems, by using a light emitting diode to provide a light of the effective wavelength and the light exit angle to the fishing of the fish to be picked up by using a limited light utilization and picking efficiency as well as the work of the worker The purpose is to provide a collection system that can increase the efficiency.

Hereinafter, the picking system according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in more detail.

1 is a front view showing a fishing system equipped with a fishing lamp according to the first embodiment of the present invention, Figure 2 is a perspective view showing a separate fishing lamp of Figure 1 shown.

1 and 2, the picking system 10 includes a support 12, first and second support lines 21 and 22, a support bar 30, a first picking lamp 100a and a second picking lamp ( 100b).

The support device includes a support 12, first and second support lines 21 and 22, and a support bar 30.

Support 12 is installed on the ship 50 to be spaced apart from each other.

The first support line 21 is connected between the supports 12.

The second support line 22 is connected between the support 12 at a position higher than the first support line 21.

As the first and second support lines 21 and 22, it is preferable to apply an iron wire capable of supporting a plurality of first and second catchers 100a and 100b.

The support bar 30 is connected between the first and second support lines 21 and 22 in a direction crossing the first and second support lines 21 and 22, that is, in a vertical direction.

A plurality of first picking lamps 100a are arranged in a horizontal direction between the support bars 30, and a plurality of second picking lamps 100b are arranged in a horizontal direction at a position higher than the first picking lamps 100a. Is mounted between the support bars 30.

As the first pick lamp 100a, a light emitting module that emits light having a correlated color temperature of 9,000 ° K to 15,000 ° K is applied.

In addition, the second collecting lamp (100b) is equipped with a light emitting module for emitting light having a correlation color temperature of 5,000 ° K to 8,000 ° K.

The light emitting diodes 135 of the light emitting module 130 applied to the first and second picking lamps 100a and 100b are preferably the same except for the correlation color temperature or color, and the rest of the structures are the same. For the sake of convenience, the detailed structure will be described collectively with reference to FIGS. 2 and 3.

The picking lamps 100a and 100b include a main body 110, a light emitting module 130, and a cap 150.

The main body 110 has a structure formed in a rectangular cylindrical shape, and functionally divided into a structure having a body 111, a heat dissipation piece 116 and a rib 118.

The body 111 of the main body 110 has a rectangular opening with an open upper portion, and has a receiving groove 112 formed in a tapered shape so that the width thereof becomes gradually narrower as it proceeds downward.

The emission angle of the light emitted from the main body 110 is formed to be 60 to 70 °.

The body 111 of the main body 110 is formed with a mounting groove 117 for mounting the cap 150 to be described later.

The seating groove 117 is formed to be retracted downward in the main body 110 to be mounted at a height below the upper surface of the main body 110 in a state where the cap 150 is mounted.

As a part forming the receiving groove 112 of the body 111, it is preferable that the angle (a) between the inner wall 113 opposed to each other along the longitudinal direction of the body 111 is applied to 60 to 70 °. .

Unlike the illustrated example, as shown in FIGS. 4 and 5, a method in which the tapered reflector 250 is coupled in the body 111 so that the upper portion thereof is opened and proceeds downward gradually becomes narrower, in this case, It is preferable that the angle b between the inner walls 213 of the reflection shades 250 forming the secondary receiving grooves is applied to each other at 60 to 70 degrees. A light emitting hole is formed at the bottom of the reflection shade 250 so that the light emitting diode 135 may be exposed.

The reflection shade 250 is preferably made of an aluminum plate of which the inner surface is mirror-treated, or applied to a silver or nickel plating so that the inner surface has a high reflectivity.

Meanwhile, the structure of the support bar for coupling the body 111 to the support lines 21 and 22 will be described with reference to FIGS. 6 to 8.

First, the first bracket 120 formed at both ends of the body 111 in a 'b' shape is fixed by using a fixing member such as a bolt at the bottom thereof, and the hole formed at the side of the first bracket 120 is a support bar. Along with the through holes 32a and 32b formed to correspond to the 30, it is possible to fix using a fixing member such as a bolt 340. The support bar 30 has a portion that is bent and twisted in the longitudinal direction to match the coupling direction between the first bracket 120 and the support lines 21 and 22 for fixing the pick lamps 100a and 100b, respectively. It is structured.

In addition, the support bar 30 has two coupling holes 32a and 32b spaced apart from each other for coupling the picking lamps 100a and 100b in the middle thereof, and the second support line 22 can be wrapped around the support bar 30. The clip portion 33 is bent to open the lower portion is formed. Clip portion 33 has a coupling hole is formed in each of the opposing portions so that the bolt can be inserted. In addition, at the lower end of the support bar 30, a second bracket 122 having a semi-circular receiving groove formed thereon to partially support the first support line 21 may be coupled by a fixing member such as a bolt 340. Coupling hole 36 is formed.

On the other hand, the support structure for supporting the body 111 can be applied to the structure different from the illustrated example.

The first pick-up lamp 100a and the second pick-up lamp 100b mounted by the support device are mounted differently from each other in the emission direction of the light emitted from the ship 50.

As shown in FIG. 9, the first catching lamp 100a is capable of guiding a fish to be picked up above the deepwater, for example, a depth of 100m to 200m below the near portion of several meters to several tens of meters from the vessel. 1 The optical axis corresponding to the center of the radiation angle P1 of the light emitted from the pick-up lamp 100a faces the water surface, but the angle P1a between the reference line S1 parallel to the water surface So and the optical axis is 35 to 45 °. It is installed.

In addition, the second pick-up lamp (100b) is shown in Figure 9 so as to induce the picking of the fish to be picked up to the vicinity of the ship to pick up the fish to be picked up from the surface of the water from a few tens of meters to hundreds of meters away from the surface As shown, the optical axis corresponding to the center of the radiation angle P2 of the light emitted from the second collecting lamp 100b faces the water surface, and the angle P2a between the reference line S2 parallel to the water surface So and the optical axis is It is installed to be 10 to 20 degrees.

Here, the reason why the light is emitted from the second pick-up lamp 100b so that the light can be emitted upward by about 20 to 30 ° with respect to the direction parallel to the surface of the water is caused by the wave 50 tilting left and right by the waves. In consideration of the fact that the ship 50 is inclined to be excessively irradiated with light only near the ship to prevent the deterioration of the picking efficiency of the fish to be picked up at a long distance. Therefore, even when the ship 50 is tilted, the light directed toward the reference line S2 parallel to the water surface So can continuously induce the induction of the fish to be picked up at a long distance.

In the arrangement of the picking lamps 100a and 100b, the light having a correlation color temperature of 9,000 ° K to 15,000 ° K emitted from the first picking lamp 100a has a relatively high component of a blue wavelength having low light absorption in seawater, and thus the vicinity of the ship. Has a merit to penetrate deep into the water surface, and the light having a correlation color temperature of 5,000 ° K to 8,000 ° K emitted from the second pick lamp (100b) has a relatively long wavelength component having low light absorption rate in a sea fog or air. By increasing the transmission efficiency to a long distance, the picking efficiency can be increased to pick up fish to be picked up in the deep and near surface of the ship.

On the other hand, unlike the illustrated example, the first and second catching lamps 100a and 100b are arranged in a row horizontally with each other, but the optical axes are arranged differently as described above, or the support lines are arranged in a single row at the center and bidirectional. Of course, you can install alternately while changing the direction.

Referring to FIG. 2 again, the heat dissipation piece 116 is formed to protrude from the body 111 to extend from one side to the bottom and the other side in a direction orthogonal to the longitudinal direction of the body 111. The heat dissipation pieces 116 are formed to be spaced apart from each other along the longitudinal direction of the body 111.

The rib 118 is formed to extend outward in the horizontal direction along the upper edge of the body 111.

The rib 118 is formed with a plurality of vent holes 119 penetrating up and down in the longitudinal direction to promote convection at a position corresponding to the region between the heat dissipation pieces 116.

The main body 110 applies a metal material painted with paint to prevent corrosion at sea, and the metal material preferably uses aluminum having high heat dissipation efficiency.

The light emitting module 130 is mounted on the bottom surface of the accommodating groove 112 of the main body 110 and emits light toward the opening of the accommodating groove 112 so that the plurality of light emitting diodes 135 are disposed on the circuit board 131. Is equipped.

The circuit board 131 applies a metal corrugated printed circuit board (MCPCB) having good heat dissipation.

As described above, the light emitting diode 135 emits white light having a correlation color temperature of 5,000 ° K to 8,000 ° K or 9,000 ° K to 15,000K.

In the present embodiment, a spectrum of the emitted light of the light emitting diode 135 fabricated to have a correlation color temperature of 6500 ° K by applying a phosphor capable of emitting white light to a blue light emitting diode chip, for example, a YAG phosphor or a silicate-based phosphor, may be used. The analysis results are shown in FIG. As can be seen from FIG. 10, more than 60% of the light is distributed in the 440nm to 460nm band and the 510 to 560nm band, which are blue to green range wavelengths, which are effective for picking squid.

On the other hand, by applying a phosphor, for example, YAG phosphor or silicate-based phosphor to emit white light on the blue light emitting diode chip to analyze the spectrum of the emission light for the light emitting diode 135 manufactured to have a correlation color temperature of 10,000 ° K The results are shown in FIG. What is necessary is just to adjust the compounding weight ratio of the fluorescent substance used as an example of the method of generating a correlation color temperature difference, and the transparent silicone used as an sealing material.

As can be seen from FIG. 11, the light intensity ratio of the 440 nm to 460 nm band is further increased by the correlation color temperature of 6,500 ° K in FIG.

The cap 150 is coupled to the body 110 to close the opening of the receiving groove 112 of the body 110.

Preferably the cap 150 is formed of a transparent material.

Reference numeral 154 denotes a sealing pad inserted between the cap 150 and the seating groove 117 of the main body 110.

On the other hand, when the cap 150 is applied in the form of a lens having a curvature appropriately adjust the curvature of the receiving groove structure and the cap 150 of the body 111 so that the radiation angle of the light emitted from the main body 110 is 60 to 70 ° You can apply it.

The picking lamps 100a and 100b of such a structure can be radiated through the circuit board 131 and the main body 110 by heat generated from the light emitting diodes 135, so that high output is possible, and the wavelength band of the emitted light is picked up. In the 440nm to 460nm band and the 510 to 560nm band, the light emission angle is limited to 60 to 70 °, thereby providing an advantage of increasing the light utilization efficiency.

On the other hand, another structure, such as picking up, is demonstrated with reference to FIG.

Referring to FIG. 12, a main body such as a picker includes a heat dissipation main board 410, a circuit board 430, and a reflector 470.

The heat dissipation main substrate 410 is a plate-shaped base plate 412 made of a metal material, an insulating layer 414 formed on the base plate 412, and a conductive pattern 416 formed of a conductive material on the insulating layer 414. It has a structure having.

The light emitting diode 135 is connected to the circuit board 430 through the conductive pattern 116.

The circuit board 430 is mounted on an edge of the heat dissipation main board 410 to electrically connect the conductive pattern 416 and the terminal pad 434 for wire connection.

The reflector 470 is bonded to the upper portion of the circuit board 430.

The reflector 470 is formed to focus forward the light emitted from the light emitting diode 135 to the side.

That is, the reflector 470 has a structure having a top and bottom through-hole having a wide upper portion and a narrow lower portion so that the light emitting diode 135 can be exposed.

The transparent cap 490 is coupled through a mounting groove formed at an upper end of the reflector 470 to transmit light while hermetically closing the opening of the reflector 470.

The transparent cap 490 may be formed of a Fresnel lens structure or another type of lens structure for inducing diffusion or condensing. In addition, unlike the illustrated example, the transparent cap 490 may be formed by filling the inner space of the reflector 470 with a transparent material such as silicon or epoxy.

Reference numeral 530 is an auxiliary plate bonded to the base plate 412.

The auxiliary plate 530 is applied to expand the heat dissipation capacity is applied to a metal material having a high heat dissipation capacity, for example, formed of aluminum or copper.

The wire 520 has a coated core wire inserted into the terminal pad 434 and coupled to the terminal pad 434 by soldering.

On the other hand, the capsule molding part 540 is formed to ensure the waterproof and corrosion resistance to salt water, the circuit board 430, the auxiliary plate 530 from the edge region of the transparent cap 490 so that the bottom of the auxiliary plate 530 is exposed. It is hermetically molded to the side of). The capsule molding part 540 may be molded by applying a waterproof and corrosion resistant material such as epoxy, urethane, or other plastic material.

In addition, the heat dissipation fin structure 550 in which the plurality of heat dissipation pieces 552 spaced apart from each other at the bottom to expand the heat dissipation capacity is arranged on the support plate 551 is shown a structure coupled to the bottom of the auxiliary plate 530, FIG. 13 illustrates a structure in which a coolant distribution pipe 570 through which coolant is circulated is coupled to the bottom of the auxiliary plate 530.

Cooling water distribution pipe 570 may also be formed in the main body 110 of FIG.

On the other hand, when the cooling water distribution pipe 570 is applied as shown in Figure 14 between the cooling water distribution pipes 570 through the connection pipe 610 in series, the connection pipe 610a connected to the outlet side of the cooling water Compressor 620 for compressing the cooling water flowing out through the condensation unit 630 for condensing the cooling water compressed in the compressor 620 by installing a cooling system that can supply the cooling water through the inlet-side connection pipe (610b) Applicable

Reference numeral 632 denotes a fan for condensation, and reference numeral 640 denotes a cooling water auxiliary tank.

On the other hand, the light emitting module 130 has been confirmed that the high efficiency of the continuous drive type repeatedly flickering drive, and an example of the control circuit of such a flashing drive is shown in FIG.

Referring to FIG. 15, the light emitting diode 135 is turned on by the driver 163 controlling the FET 167, which is a switching element, in response to a driving signal input from the controller (not shown) through the control signal input terminal 161. Drive on / off. Reference numeral 165 is a buffer.

In the driving-on mode for driving the light emitting module, the control unit may drive the light emitting diode to be blinked while repeatedly turning on / off, but the lighting holding time and the unlit holding time are preferably 0.1 to 0.3 seconds.

On the other hand, in order to find out the reaction characteristics for the squid picked fish was put in the tank and the test was performed. Since the catched squids are less responsive to light after 2-3 days after being put in the tank, the experiment of fish behavior was carried out by putting the squids caught the previous night into the tank in the morning of the same day and then incubated. The night was performed after sunset. The water temperature in the tank ranged from 10-23 ℃ depending on the date of the experiment, and the types of experiments were evenly distributed so that there was no effect on the water temperature.

<Experiment Tank & Equipment>

In order to facilitate the observation of the squid's fishing behavior and to quantitatively indicate the moving distance, the experimental tank was 20m in length, 0.8m in width and height, and 0.7m in height from the bottom to the surface. In addition, the 20m tank was divided into 16 sections of 1.25m each so that the location of the cuttlefish collected in the light for a certain time could be determined.

The LED lamps used in this experiment were about 50W lamps with 7W7 arrays of 1W LED elements, and five types of white, red, yellow, green, and blue series, depending on the wavelength, were used. In addition, a 30-degree reflective shade was attached to the front of the lamp, and the angle of the LED lamp was adjusted so that the positive and negative light was located at the boundary between the bottom of the first section and the bottom of the second section. This is also to check the characteristics of the shaded area of the cuttlefish.

First, the first experiment was to place five lamps in turn on one side of the tank in a dark place, and put 30 squids in the middle of the tank in a width section of 1m in the length direction, then illuminate the light for about 30 seconds and remove the net frame. After 5 minutes, the number of squids in each section was recorded. In the second experiment, two LED lamps with different wavelengths are placed at both ends of the tank so that they face each other. Like the first experiment, 30 squids are placed in the middle of the tank in a width of 1m in the longitudinal direction, and then the light is turned on. After about 30 seconds, the net was removed and the population of the cuttlefish for each section was recorded after 5 minutes. In the third experiment, the LED lamps of the same wavelength for white light and blue light are placed at both ends of the tank so that they face each other, one lamp flashes at intervals of 0.01 to 0.3 seconds, and the other lamp is continuously turned on. In this case, the population of each section of the tank was recorded as in the second experiment. The method of the fourth experiment is the same as the second one, and in order to obtain more accurate information on the wavelength in the blue light having the most effective flocking effect in the previous experiment, the lamps of wavelength 450nm and 490nm, 450nm and 460nm were reinstalled and compared with each other.

The first experiment was performed 5 times each, 25 times, the second, third, and fourth experiments were performed 10 times each, 100, 20, 20 times. The power used was 28W with the principle of supplying the same energy.

In addition, the wavelength of each LED lamp was analyzed by using a spectrophotometer (Spectro meter USB4000, THOR Co.) capable of spectra analysis by wavelength to accurately measure the wavelength characteristics of the LED lamp used in the experiment. The measurement position was performed at a distance of 5 m from the lamp.

White light mainly appeared to be a mixture of blue light, green light and some yellow wavelengths, and some yellow wavelengths were mixed. The wavelength values of the lamps were 634 nm for red light, 596 nm for yellow light, 523 nm for green light, and 454 nm for blue light. The light outputs were similar in the same order.

<Preferences of Squid LED Lamps by Color>

The most preferred lamps were blue, followed by white and green lamps, and the least preferred lamps were red and yellow lights. Unexpectedly, the cuttlefish showed more drunk mania behaviors in red or yellow wavelengths than diurnal activity. The squid, which is located in the center of the tank, moved to the curious side of the light as soon as the net was removed, and later placed on the shadow of both ends of the tank. After 5 minutes, there were relatively few squids in the brightest section after the shaded section. During the five minute period, two to three animals reciprocated the tank and the rest did not have any significant movement. In other words, the cuttlefish showed positive daylight behavior for blue light, green light and white light, and drunk light action for red light and yellow light.

<Preference between squid's LED lamps and flashing lights>

As a result of comparing the squid's preference between the LED lamps and the flashing lights, the flashing lights were superior to the blue and white lights. The quantitative value of the number of squids shifted was 10.6% higher than the blue light (34.3%) and 13.7% higher than the normal light (26%). Therefore, the cuttlefish seems to have a lot of curiosity about blinking.

<Preferance between the cuttlefish's blue LED lamps>

As a result of comparing the preference between the blue LED lamps of the cuttlefish, the 450nm lamps prevailed in the preference comparison experiments of the wavelength 450nm lamps and the wavelength 490nm lamps. The quantitative value of the number of squids moved was 12.3% higher for the 450nm lamp (44.3%) than for the 490nm lamp (32%). In addition, the 450nm lamp (37.3%) was 1.5% superior to the 460nm lamp (35.8%), and the two lamps had the same performance. Therefore, among blue LED lamps, short-wavelength lamps with a wavelength range of 450-460nm are considered to have high performance for squid.

On the other hand, according to the results of the experiment, it may be desirable to use blue light for picking up from a simple picking efficiency point of view, but the worker working in the fishing field when the blue light only irradiated the color of the object and the surrounding environment Difficulty in discriminating, and easily fatigued, the problem that long-term normal operation is difficult.

Therefore, as described above, the white light generated by applying YAG or a silicide-based phosphor to a blue light emitting diode chip may be used to reduce visual fatigue of the worker while reducing visual fatigue of the worker. The picking efficiency can also be improved by blue light of 440 to 460 nm and green light of 510 nm to 560 nm.
