BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a heat sink structure of an LED pick-up lamp having a hollow housing, and an LED pick-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pick-up lamp used for collecting fish at a predetermined point for catching fish such as squid.

Light-loving fish such as horseshoe, sardines, and squid (hereinafter referred to as 'hornbill fish') have a habit of gathering in response to light, and light is used for fish catching hornbill.

As a concrete example, in case of squid, a large amount of light bulb is installed on the ship and the light is emitted at night, and the squid gathered around the ship is caught through fishing.

Light is a very important issue in fisheries for catching fishes. In the past, metal lamps, which have poor energy efficiency, have been used as an economic burden on fishery activities.

In order to solve this problem, an LED pick-up lamp using an LED (light-emitting diode-LED) as an illuminant has been found.

Korean Patent Application No. 10-2009-0020125 discloses a structure of an LED pick-up lamp (light-emitting diode pick-up) using an LED (light-emitting diode) as an illuminant.

The heat dissipation structure is very important in the structure that uses the LED as the light emitting means like the LED light.

That is, since the luminous efficiency of the LED is lowered as the temperature is higher, it is very important for the luminous efficiency of the LED to rapidly emit the heat generated by the LED.

For this reason, Korean Patent Application No. 10-2009-0119826 discloses a structure of a headlight having a structure for rapidly releasing heat generated in an LED, but the heat radiation effect is not expected to be achieved.

On the other hand, LED lights are very economical because they are very energy-efficient and can save a lot of money when considering the consumption of energy for light emission.

However, in practice, it is recognized that the LED pick-up lamp is not suitable for fish catching the rhinoceros due to the problem that the catch amount is greatly reduced in the ship using the LED pick-up light.

For this reason, LED lights are not widely available.

Korean Patent Application No. 10-2009-0020125 Patent Application No. 10-2009-0119826

An object of the present invention is to provide a heat dissipating structure of an LED holder and an LED holder to which the LED is applied, using an LED as a light emitting unit, an excellent heat dissipating effect, and an excellent energy efficiency.

Another object of the present invention is to provide an LED pick-up which does not deteriorate the catch because of its excellent picking effect.

In the present invention, a plurality of radiating fins are positioned on the hollow inner wall in a structure in which hollows are formed on the front and rear of the pick-up lamp, for example, because the LEDs are positioned on the front and rear sides of the pick- Air is introduced into the hollow and is passed through the radiating fins so as to cool the holder.

Therefore, the LED pick-up lamp of the present invention has a housing in which a plurality of LEDs are provided to radiate light to the outside and form a hollow.

In addition, it has a plurality of radiating fins protruding from the inner wall of the housing.

Further, it has a blowing fan which is located at the upper or lower portion of the hollow and allows the air outside the hollow to flow into the hollow and then to be discharged.

Since the LED lamp is used as a luminous body, a plurality of heat-radiating fins are positioned on the inner wall of the cavity in the structure in which the energy consumption is small and the hollow is formed on the front and back of the lamp, , And a blowing fan is located at the upper or lower part of the pick-up lamp, and the outside air is blown into the hollow by the blowing fan to pass through the radiating fin.

In addition, in the case where the air flow path setting body for blocking the central portion of the hollow is formed at the lower portion of the blowing fan so that the suction force by the blowing fan acts along the hollow inner wall, There are excellent features.

Particularly, when the air flow path setting body is pointed toward the blowing fan, the suction force is prevented from being weakened, and the external air flows through the radiating fin, so that the radiating efficiency is further improved.

In addition, the reference omnidirectional lobe, lower omnidirectional lobe, reference posterior lobe, lower posterior lobe, A reference side light emitter; When the lower light distribution unit is provided, the catching effect is excellent and the catch amount is not lowered.

Further, when the reference light emitting portion, the lower side light diverging portion are located on the front left side of the housing, the front right side of the housing, the rear left side of the housing, and the rear right side of the housing,

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

The present invention relates to an LED pick-up lamp.

Accordingly, it has a housing 10 on which an LED (light emitting diode-LED) that receives power and emits light for picking up is provided.

However, the present invention has an object to provide a heat dissipation structure of an LED pick-up and the like, and an LED pick-up and the like to which the heat dissipation structure is applied.

Particularly, it has an object to make the heat dissipation effect excellent in the structure in which the hollow 14 is formed in the lid or the like because of the reason that the LED is disposed in front of and behind the lid.

The inventor of the present application has found out a structure that does not decrease the amount of the outer part while using the LED pick-up light through various studies and experiments.

In addition, it was concluded that light should be irradiated at least at the front and rear of the earlobe in order to reduce the installation quantity of the earlobe by installing such LED light in the longitudinal direction at the center of the ship.

In this way, it is preferable that the housing has the hollow 14 in the structure of the LED light bulb which irradiates light to the front and rear of the pick-up lamp.

That is, a hollow 14 is formed in the rear of the LED so that heat radiation is better.

However, forming the hollow 14 has a limitation in raising the heat radiation effect.

For this reason, the present invention has a plurality of radiating fins 11 protruding from the inner wall of the hollow 14 of the housing (protruding toward the center of the hollow 14).

And a blowing fan 50 positioned at the top or bottom of the hollow 14 to allow the air outside the hollow 14 to flow into the hollow 14 and then to be discharged.

That is, in the present invention, since the outside air is discharged through the hollow 14 through the blowing fan 50, the hollow 14 is cooled, thereby cooling the housing 10 as a whole to improve the cooling efficiency of the LED will be.

However, if there is no other means, there arises a problem that the contact efficiency between the external air introduced into the hollow 14 and the radiating fin 11 is low.

That is, since the plurality of heat dissipating fins 11 are located near the inner wall of the hollow 14, the resistance is large in the flow of the external air and the resistance in the vicinity of the center of the hollow 14 is relatively weak, It will be smooth.

If this phenomenon occurs, the heat dissipation effect is lowered.

In order to solve this problem, an air flow path setting body 80 for blocking the central portion of the hollow 14 at the lower portion of the blowing fan 50 so that the suction force by the blowing fan 50 acts along the inner wall of the hollow 14 .

However, the structure that simply blocks the central portion of the hollow 14 may result in weak wind power.

Therefore, it is preferable that the air flow path setting body 80 is formed in a pointed shape toward the direction of the blowing fan 50, thereby preventing the central portion of the hollow 14 from being blocked and weakening the wind power.

As a specific example of the pointed shape toward the air blowing fan 50, there is a cone, a pyramid, a cone cut at the upper part, and a pyramid cut at the upper part.

On the other hand, energy saving effect can be confirmed in fishery activities such as squid fishing using conventional LED pick-up lamps, but there is a problem that the catch amount is not much larger when conventional metal lamps are used.

However, for some reason, it has not been revealed whether the amount of catch in the fishing activity of the LED fishing rod used decreases.

The inventor of the present application found out that, in the case of the LED light bulb in the case of the LED light bulb, the light emitted by the light emitting diode (Which can be described as light netting in that light is crossing each other to form a net shape and can hold a rhinoceros) can not form a perfect circle.

It is not the active part of strong light which is gathered by light after squirrels are gathered by light, but the lower part of light fixture (ship) which is relatively weak in light (boundary of bright light and shadow, (The area where shadows are formed by shadows). (The hornblown fishes themselves feed themselves in a place where they can hide their body, and the plankton is located in the boundary between bright light and shadow, This is because it is more active in the shadow formation region due to

As a result, the light-gathered bright-eared fishes move to the shadow-forming area by the bright light and the shadow boundary and the shadow fixture (1), so that the light crowd (100) (1) is inwardly connected to each other, the effect of picking up is lowered.

In other words, if a flock of light is not formed, or a part of the flock of light is formed that is not connected to one, it is dispersed to the dark part of the outside of the flock through the unconnected part of the flock, Can not be collected in a predetermined space (an area where shadows are generated by the bulb holder).

This is because the number of fishes in the lower part of the ship where the fishing is done is small and the catch is small.

Fig. 1 (A) is a view for explaining a crowd of light formed in a state where an LED pick-up lamp is installed only on left and right sides of a squid job ship, and a portion intersecting between lights emitted from a pick-up is generated.

Fig. 1B is a view for explaining a crowd of lights formed in a state in which an LED pick-up lamp is installed at front, rear, left, and right sides of a squid job ship, and a portion intersected between lights emitted from a pick-up is generated. (However, FIG. 1 shows a case in which an LED that emits light toward the front of the housing 10 and an LED indicator with an LED that emits light in the left and right directions of the housing 10 are used.)

In the structure shown in Fig. 1 (A), the average catch was very small, and in the structure B in Fig. 1, the average catch was larger than that of the conventional metal lamp, as well as the structure in Fig.

Therefore, it was found that it is very important to be able to form a bundle of lights connected with one another in a light emitting diode (LED) using a light emitting diode having a strong directivity and a weak diffusing property.

In order to form such light clusters, the spacing between the pick-up lamps should be such that the light emitted from one of the pick-ups and the other crosses the light emitted from the other pick-up.

At this time, it is preferable that the point where the light emitted from one of the pick-ups and the light emitted from the other pick-ups intersect with each other at the point where the light cluster 100 is formed or between the light cluster and the pick-

In the case of using a conventional LED light bulb, since the distance between the LED light bulb and the LED light bulb should be set very close to each other, a large number of bulb lights must be installed.

It is a structure that can solve these problems and form a light cluster smoothly, and it presents a structure that emits light in the forward, backward, and lateral directions of the LED light.

However, the structure that emits light in forward, backward, and sideways directions of the tongs is a problem in that when the tongue strikes on the tongue fixture (squid job vessel) due to the waves, Lt; / RTI >

For this reason, according to the present invention, light is irradiated in at least two directions among all directions by being irradiated differently at predetermined angles when light is irradiated to the front direction of the housing 10 (forward direction of the barrel).

In addition, when the light is radiated in the lateral direction of the housing, the light is irradiated differently in at least two directions among the lateral directions by being irradiated differently at predetermined angles.

In addition, when light is irradiated to the rear of the housing, the light is irradiated differently in at least two directions among the backlight by being irradiated differently at a predetermined angle.

That is, a portion where the LED is installed includes a reference forward light emitter 21, a lower forward emitter 23, a reference rear emitter 25, a lower rear emitter 27, a reference emitter 33, And a lower side light diffusing portion 33, as shown in Fig.

The reference omni-directional light emitter 21 is a portion provided with an LED 21a that emits light in any one of the forward directions of the housing 10 as a reference.

The lower omnidirectional light emitter 23 is a portion provided with an LED 23a for irradiating light downward from the forward direction light emitter 21 of the housing 10 in the forward direction.

The reference back light emitter 25 is a portion provided with an LED 25a for emitting light in either direction as a reference of the rear of the housing 10. [

The lower rear light emitter 27 is a portion provided with an LED 27a for irradiating light toward the lower side than the light irradiation direction through the reference rear light emitter 25 in the rear of the housing 10. [

The reference lateral direction light emitting portion 31 is a portion provided with an LED 31a for emitting light in either one of the lateral directions of the housing 10 as a reference.

The lower side light emitting portion 33 is a portion provided with an LED 33a that irradiates light downward in the lateral direction of the housing 10 from the light irradiation direction through the reference side light emitting portion 31.

Each of the LEDs 21a, 22a, 23a, 25a, 26a, 27a, 31a, 32a, and 33a may be mounted on a printed circuit board as in the prior art.

Also, a method of supplying power to the LEDs 21a, 22a, 23a, 25a, 26a, 27a, 31a, 32a, and 33a may be implemented in a conventional manner.

And an upper omnidirectional light emitter 22 provided with an LED 22a for irradiating light upward from the reference light emitter 21 in the front direction of the housing 10 have.

Further, it may further include an upper rear light emitter 26 provided with an LED 26a for irradiating light upward from the irradiation direction of light through the reference rear light emitter 25 in the rear of the housing 10.

It is further provided with an upper side light emitter 32 provided with an LED 32a for irradiating light upward from the irradiation direction of light through the reference light emitting part 31 in the lateral direction of the housing 10 .

This configuration irradiates the light to the front, side, and rear directions of the housing 10 at least at three or more points, respectively, so that even if the pendulum is strongly swung by the waves, There is a maintainable feature.

The reference side light emitting portion 31, the upper side light emitting portion 32 and the lower side light emitting portion 33 are disposed on the front left side of the housing 10 and the front right side of the housing 10, the rear left side of the housing, (A in Fig. 2 is a front view of the LED pick-up lamp according to the present invention, which is located on the front left side of the housing and on the front right side of the housing).

In the present invention, the reference light emitting portion 31, the upper side light emitting portion 32, and the lower side light emitting portion 33 are arranged on the left side of the reference light emitting portion 21 with reference to the light emitting direction, Or an LED that emits light toward a direction (P1 or P2) that is rotated by 30 to 50 degrees to the right. (See Fig. 3)

That is, when the LEDs 31a, 32a, and 33a that emit light in the lateral direction of the housing 10 are rotated 90 degrees to the left or right when the light emitting direction P of the reference forward direction light emitting portion is referred to, (Refer to FIG. 4), the light emitted in all directions of the housing 10 and the light emitted in the lateral direction of the housing 10 are emitted only toward the left side (P3, P4, It is difficult to form a dense net-shaped light cluster.

The intersection point of the light emitted in the front direction of the housing 10 and the light emitted in the lateral direction of the housing 10 should be broadly formed to form a dense network of light bundles.

In the present invention, the light divergence directions of the upper front light emitter 22 and the lower front light emitter 23 are 5 ° to 40 ° from the upper and lower sides in the light diverging direction of the reference front light emitter 21, (P5, P6) in the direction of rotation (see Fig. 5).

That is, when the angle between the reference forward direction light emitting portion 21 and the upper forward light emitting portion 22 and the angle between the reference forward light emitting portion 21 and the lower forward light emitting portion 23 are too small or large, The effect of picking up in a state of being low is obtained.

It has been found that preferable angles? 1 and? 2 are 5 to 40 degrees.

More preferably, the light divergent direction P5 of the upper omnidirectional light emitter 22 is rotated 5 to 15 degrees upward from the light diverging direction of the reference omnipoise emitter 21.

The light divergent direction P6 of the lower forward light incidence portion 22 was rotated by 15 to 25 degrees downward in the light divergence direction of the reference forward light incidence portion 21.

The angular relationship between the reference back light emitter 25 and the upper back light emitter 26 and the angular relationship between the reference back light emitter 25 and the lower back light emitter 27 are the same as the reference forward light emitter 21, The light escape portion 22 and the lower forward light escape portion 23, respectively.

With the same principle, the light divergence directions of the upper side light emitting portion 32 and the lower side light emitting portion 33 are also rotated 5 to 40 degrees from the upper and lower sides in the light emitting direction of the reference side light emitting portion 31 (P7, P8) (see Fig. 6).

That is, it has been found that the preferred angles? 3 and? 4 are 5 to 40 degrees.

Of course, it is more preferable that the light emitting direction P7 of the upper side light emitting portion 22 is rotated 5 to 15 degrees upward from the light emitting direction of the reference forward light emitting portion 21. [

The light emitting direction P8 of the lower light emitting portion 22 was a direction rotated by 15 to 25 degrees downward in the light emitting direction of the reference forward light emitting portion 21. [

Even if the reference forward light emitter 21 and the reference light emitter 31 emit light horizontally in the above-described structure, the LED light bulb of the present invention is inclined as a whole and the light emitted from the lower forward emitter 23, The lower side light emitting portion 33, the reference forward direction light emitting portion 21 and the reference side light emitting portion 31 can emit light toward the marine underside of the ship.

In addition, the upper forward light emitter 22 and the upper lateral light emitter 32 may also emit light toward the seabed.

However, in the absence of waves, light is emitted toward the upper part of the horizon and the light is emitted toward the seabed when the wave of the excitation of the pick-up device occurs. (Even if a wave is generated and the reference omniazimuth light emitter 21 illuminates a point close to the ship, the point where the reference omniameter emitter 21 illuminates is referred to as an upper omni emitter 22. [ The principle that it becomes a form to shine)

As described above, the angle between the reference forward direction light emitting portion 21 and the upper forward light emitting portion 22 and the angle between the reference forward light emitting portion 21 and the lower forward light emitting portion 23, The angles (? 1,? 2,? 3,? 4) between the crests 31 and the upper side light emitting portion 32 and between the reference side light emitting portion 31 and the upper side light emitting portion 32 satisfy the above- 5 ° to 40 °, it is possible to obtain an improved picking effect through the lower light emitting portion 33 of the lower omnipolar light emitting portion 23 while satisfying such an installation state (a preferable installation state of the above described pick-up lamp).

In the above-described structure, the LEDs 21a and 31a of the reference omniazimuth light emitting portion 21 and the reference light emitting portion 31 have the effect of attracting arc-irradiated fishes located relatively far away.

In addition, the lower omnidirectional light emitting portion 23 and the lower light emitting portion 33, which emit light toward the vicinity of the ship, have.

In the present invention, the lower end of the housing 10 may further include a lamp 40 that emits light downward so as to illuminate the deck of the ship on which the housing 10 is installed.

That is, when the conventional metal lamp pick-up lamp is used, the deck of the ship is very bright, so that it is not difficult to work.

Rather, too bright light was enough to damage the eyes of the crew.

However, in the case of LED lights, the straight line of light is strong and the diffusivity is weak, which makes it difficult to illuminate the deck of the ship.

Of course, a separate illuminating device may be provided on the ship to illuminate the deck, but a lamp 40 for illuminating the deck through the LED pick-up lamp is provided on the ear.

The lamp 40 may be disposed at a lower end of the housing 10, and may be an LED lamp. It is further preferable that a lens for diffusing light is provided in front of the LED.

2, the housing 10 has two parts, one of which is directed toward the front of the earpiece, and the other of which is directed toward the rear of the earpiece.

The reference omnidirectional light emitter 21, the upper omnidirectional light emitter 22 and the lower omnidirectional light emitter 23 are provided at one portion and the reference light emitter 25, An upper rear light emitter 26 and a lower rear light emitter 27 are provided.

In FIG. 2, the rear side of the housing 10 faces each other, and each of the light emitting portions is symmetrical to each other.

That is, the reference forward direction light emitting portion 21, the upper forward light emitting portion 22, the reference lateral direction light emitting portion 31, the lower side light emitting portion 33, and the like located in the left portion of the housing 10 are housed in the housing 10, Symmetrical with the reference rear light emitter 25, the upper rear light emitter 26, the reference side light emitter 33 and the lower light emitter 33 located on the right side of the base 10, will be.

In this structure, it is possible to further include an interval adjusting means 60 for adjusting the distance from the lower forward arcsector 21 to the lower rear arcsector 27.

The gap adjusting means 60 may be implemented in various forms of gap adjusting means applied to various industrial fields.

2, a right side portion of the housing 10 is connected to a guide 61 fixed to a left side portion of the housing 10. When the nut 62 is fastened, the right side portion of the housing 10 is fixed to the guide 61 Or the nut 62 is loosened so that the right portion of the housing 10 can move along the guide 61. [

When the left side portion of the housing and the right side portion of the housing are hingedly coupled to each other in the structure having the gap adjusting means 60, light irradiation through the lower forward ocular light emitting portion 21 through the gap adjusting means 60 It is possible to adjust the direction of the light passing through the lower rear flare part 27 on the right side and the direction of the light passing through the lower rear flare part 27 so as to illuminate near the fixture fixture 1 or illuminate a distant place.

In the present invention, each light emitting part, that is, the reference forward direction light emitting part 21, the upper forward light emitting part 22, the lower forward light emitting part 23, the reference lateral direction light emitting part 31, The light emitting part 32, the lower side light emitting part 33, the reference rear light emitting part 25, the upper rear light emitting part 26 and the lower rear light emitting part 27 are provided with LED lamps And ease of installation and wiring of the LED.

The more the light emitted from each of the LEDs 21a, 22a, 23a, 25a, 26a, 27a, 31a, 32a and 33a intersects with the light emitted from the adjacent position, Can be formed.

For this purpose, it is effective to use a method in which each of the LEDs is installed at an intersection of an appropriate distance and a light irradiation angle, or that a convex lens 71 or a concave lens 72 is provided in front of the LED .

That is, the light emitted from the LEDs 21a, 22a, 23a, 25a, 26a, 27a, 31a, 32a and 33a is diffused through the convex lens 71 and the concave lens 72, This means that even if the tongue is not installed very tightly, it is a perfectly connected one and the intersection of light and light can form a lot of light.

In the case of the convex lens 71, the light corresponding to the light-convergent type lens is diffused again, and as a result, the light can diffuse (see A in FIG. 8).

On the contrary, in the converging focus F, strong light due to condensation is diverged, so that the effect of picking up is increased, so that the convex lens 71 is preferable to the concave lens 72.

The more intersection of light and light, the more robust forms of light can be created.

In order to allow more light and light emitted from the LED lamp to cross each other, a single LED lamp (a reference forward light emitter 21, an upper forward emitter 22, a lower forward emitter 23, A plurality of convex lenses 71 and a concave lens 72 may be provided in each of the LED lamps located in the light emitting part 31, the upper side light emitting part 32, the lower side light emitting part 33, . (Not shown)

That is, since each of the convex lens 71 and the concave lens 72 condenses or diffuses light, when a plurality of convex lenses 71 and concave lenses 72 exist in one LED lamp, The intersection of light and light is more generated.

However, in order to provide a plurality of convex lenses 71 and a concave lens 72 in one LED lamp, the structure becomes complicated due to a large number of engagement parts of the convex lens 71 and the concave lens 72, The property is deteriorated.

In order to solve this problem, as shown in FIGS. 8A and 8B, a plurality of the light collecting portions 71a protruded for collecting light may be formed in one convex lens 71. FIG.

That is, the convex lens 71 having the plurality of light collecting portions 71a is positioned in front of the LED.

Of course, in the case of the concave lens 72, a plurality of light diffusing parts 72a concaved and recessed to diffuse light may be formed in one concave lens 72.

When a convex lens 71 having a plurality of light collecting portions 71a is provided in one LED lamp, any one of the plurality of light collecting portions may be formed so that the focal point of the light converging portion is closer to the LED than the other light collecting portions. 8, A)

That is, one of the plurality of light collecting portions 71a is relatively close to the LED and the other is relatively far from the LED.

In this case, since the converging focus F is changed, a point where bright light is diffused by condensing differs and more intersection of light is generated.

In addition, the converging focus F closer to the LED (the upper one in Fig. 8) is irradiated with light to a shallower depth and the converging focus F is far from the LED (the lower one in Fig. 8) The light is irradiated to a place where the depth is relatively deep, so that the effect of picking up is increased.

9, the two light condensing portions 71a located below the respective LED lamps protrude in a hemispherical shape, and the upper light collecting portion 71a has a relatively long length in the left and right directions, And the projecting height is lower than the hemispherical shape (the cross-sectional surface is shaped like A in Fig. 8).

Therefore, the condensing focal point of the condensing portion 71a located at the upper portion is close to the LED, and the condensing focus of the lower condensing portion 71a is relatively far from the LED.

In the present invention, each of the light emitting portions (reference forward light emitting portion 21, upper forward light emitting portion 22, lower forward light emitting portion 23, reference lateral direction light emitting portion 31, Ventilation holes 12 and 13 for ventilation are provided between the mountain portion 32, the lower lateral light projecting portion 33, the reference rear light projecting portion 25, the upper rear light projecting portion 26 and the lower rear light projecting portion 27 .
