Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat sink structure of an LED pick-up lamp having excellent heat dissipation effect due to immersion of an LED mounting part in a liquid, and an LED pick- lamp in which that is applied}

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, there is a problem that the LED light is not used.

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, which is excellent in energy efficiency and excellent in energy efficiency, .

In the present invention, the liquid filled in the case has a form in which the LED mounting portion is immersed, thereby excellently radiating the LED indicator.

Also, convection of the liquid by heating and cooling occurs, and the convection phenomenon causes the liquid to flow from the lower part to the upper part through the flow hole formed inside the LED mounting part, so that the heat radiating effect is further improved.

The LED filler lamp heat dissipation structure of the present invention has a case filled with liquid and made of a material through which light passes.

Further, it has an LED mounting portion provided with an LED and immersed in the liquid filled in the case.

Since the LED pick-up light-emitting structure according to the present invention places the LED mounting portion in the liquid-filled case so as to be immersed in the liquid, the heat generated by the LED is rapidly transferred to the liquid, and the liquid rapidly discharges heat to the outside. It has excellent heat dissipation effect and low damage of LED module.

In addition, when the LED is installed in the LED mounting portion, it is possible to freely implement the light emitting angle, for example, to radiate light in four directions (forward, backward, left and right) have.

In addition, when the liquid is filled in the case, a space for preventing the case from being cracked due to expansion of the liquid is filled in the case so that safety is excellent.

When the liquid is allowed to flow from the lower portion to the upper portion along the flow hole formed in the LED mounting portion due to the convection of the liquid, the heat of the LED mounting portion is transmitted to the liquid more quickly.

In addition, when LEDs that emit light toward a relatively high point in the same direction among four directions of front, rear, left, and right of the pick-up and an LED that emits light toward a relatively low point are installed, And is characterized in that the picking effect can be stably maintained.

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 present invention.

It is an object of the present invention to provide a heat dissipation structure of an LED holder and an LED holder to which the LED module is applied, as well as being excellent in energy efficiency due to excellent heat dissipation effect and less damage to the LED module.

The inventors of the present application paid attention to a heat dissipation structure through a liquid in various researches and experiments for attaining the above object.

The heat transfer efficiency of a liquid is several tens times higher than that of air.

Particularly, in the case of liquid silicone oil, the heat transfer efficiency is several hundred times to several thousands times as high as that of air, and has characteristics ranging from tens to hundreds of times of water (pure water).

In addition, it has excellent electrical insulation, composed of heat-resistant siloxane bonds and organic methyl groups, and has a flash point as high as 300 ° C.

In addition, there is a feature that the corrosion of metals such as aluminum and stainless steel is not promoted, and the change of the viscosity with temperature changes is small.

In addition, surface tension is very low compared to water and general synthetic oil.

The inventor of the present application has proposed a structure in which a liquid is applied to a heat dissipation structure of an LED holder and a shape in which LED is immersed in a liquid filled in a case to achieve the object of the present invention.

Therefore, the LED pick-up and heatsink structure of the present invention has a case 40 made of a material filled with the liquid 30 and passing light therethrough.

An LED mounting portion 10 provided with LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b and 13c and immersed in the liquid 30 filled in the case 40, .

The light emitted from the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c is smoothly emitted to the outside of the case 40 as the case 40 is transparent.

It is also preferable that the outside of the case 40 is heat-exchanged with the outside air so that the heat is quickly released to the outside.

The case 40 may be made of a variety of materials such as synthetic resin and tempered glass, but it is preferably made of a material having excellent heat transfer efficiency.

Glass is a preferable material because of its excellent transparency and heat transfer efficiency.

The light emitted from the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c is more likely to be emitted from the air than in the case where the LED mounting portion 10 is immersed in the liquid It spreads widely.

That is, when the light of the LED is irradiated in the air, the straightness of the light is strong, but the diffusivity is weak.

However, when the LED is immersed in liquid, the linearity of light is somewhat lowered, but the diffusivity of light is relatively improved.

In addition, even when the outside of the case 40 has a curved shape (a shape similar to that of a normal incandescent lamp), the linearity of light emitted from the LED is somewhat lowered, but the light diffusivity is relatively improved.

The diffusibility of light in the LED light and the like greatly affects the formation of the light cluster 200 to be described later, and is very important for improving the picking effect (refer to the explanation given later).

The liquid most suitable as the liquid in the above description is liquid silicone oil.

Since such liquid silicone oil is very excellent in electric conductivity, the LED may directly contact the liquid silicone oil.

However, in the case where the electric conductivity is poor, such as water, as the liquid, the LED mounting portion 10 is enclosed by a film or a transparent case so that the LED mounting portion 10 is immersed in the liquid in a protected state.

The liquid is expanded when it is excessively heated to a predetermined temperature or more, so that the liquid is completely filled in the inner space of the case 40 when the liquid is filled in the case 40, there is a risk of a safety accident.

It is preferable that a space 42 is formed in the case 40 so as to prevent the case 40 from being cracked due to the expansion of the liquid 30 when the liquid is filled in the case 40. [

That is, when the liquid 30 is heated to a high temperature and inflated, liquid is filled in the space 42 in which the liquid is not filled, thereby preventing the case 40 from being broken.

In consideration of the object of the present invention, it is preferable to widen the contact area between the LED mounting portion 10 and the liquid 30 described above.

However, the structure in which excessive irregularities are formed in the LED mounting portion 10 in order to widen the contact area between the LED mounting portion 10 and the liquid 30 interferes with the convection phenomenon of the liquid, thereby causing a reduction in the heat radiation effect.

That is, in the case of the attached drawings, the heated liquid rises to the upper side of the case 40, and when the cooling by the heat radiation is performed, the convection phenomenon that descends toward the LED mounting portion 10 should be smoothly performed,

In order to smoothly carry out the convection phenomenon and to increase the contact area with the liquid, a flow hole 12 penetrating upward and downward can be formed in the LED mounting portion 10.

That is, a flow hole 12 penetrating upward and downward is formed in the LED mounting portion 10 so that the liquid 30 can flow from the lower portion to the upper portion due to the convection of the liquid 30.

This structure is more preferable for a structure in which the LED mounting portion 10 has a columnar shape, in particular, for the structure of the LED mounting portion 10 having a large thickness.

Of course, the radiating fin 13 may be positioned on the outer circumferential surface of the LED mounting portion 10 so that the contact area with the liquid can be made wider.

In this case, the space 14 between the radiating fin 13 and the radiating fin 13 may be positioned so as to extend upward and downward when the radiating fin 13 is positioned.

That is, when the liquid is moved upward by convection, the space 14 between the radiating fin 13 and the radiating fin 13 smoothly escapes.

In the present invention, the heat sink 20 may further include a heat sink 20 that receives the heat of the liquid 30 and discharges the heat to the outside, outside the case 40.

Such a heat sink 20 can be realized in various known forms for heat dissipation.

However, since the temperature of the upper portion of the case 40 is higher, it is preferable that the heat sink 20 is positioned above the lower portion of the case 40.

The attached heat sink 20 shown in FIG. 4A has a cap shape fixed to the upper portion of the case 40.

4 is a structure in which a plurality of radiating fins 21 are positioned above the case 40. [

2 has a structure in which a plurality of radiating fins 23 are positioned outside the cap body 22 located at the upper portion of the case 40 and has excellent heat radiation performance.

In the present invention, a point forming the lower end portion of the case 40 is protruded downward from the lower end of the LED mounting portion 10 to the lower portion of the case 40 to form the protruding portion 41 The convection phenomenon is more smoothly performed.

In other words, the temperature of the projecting portion 41 is relatively lower than that of the other portions, so that circulation of the liquid 30 is more smoothly performed.

As in the present invention, the structure using the case 40 and the liquid 30 does not affect the mounting angle of the LEDs or the like. Therefore, when the LED is mounted on the left, right, front, Since it can be installed in any direction, there is a feature that a light emitting angle can be freely implemented.

That is, when the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c are installed in the LED mounting portion 10, light can be emitted in four directions of forward, It is possible to freely implement the angle of divergence of light.

Freely embodying the angle of light divergence is a very important consideration when considering the formation of light clusters to be described later.

By implementing the above-described heat-radiating structure of the present invention to realize an LED pick-up lamp, it is possible to improve the energy efficiency of the pick-up and prevent the damage of the LED module.

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 expressed as a light net in that light is crossing each other to form a net shape and can hold a rhinoceros) can not form an intact circular shape (a complete circular shape in the lateral direction) .

It is not the active part of strong light like squid, but the lower part of light fixture (ship) which is relatively weak in light (boundary of bright light and shadow, In which shadows are formed).

It was judged that the hunting fishes themselves were feeding in places where they could hide their bodies, and plankton was more active in the shadow areas formed by bright light and shadows, and shadow fixtures (1).

As a result, the rhombus caught by the light travels to the shadow region formed by the boundary between the bright light and the shadow, and the shadow fixture (1) Is not in the form of a one-piece linkage with the stick-on fixture inside, the effect of picking up will be lowered.

In other words, if a flock of light can not be formed, or if a part of the flock of light is formed that is not connected to one, then the flounder that is gathered along with the light escapes into the dark part of the outside of the flock through the part where the light is not connected, It is impossible to collect adult fishes in a predetermined space (such as a region where shadows are generated by a pick-and-place fixture).

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.

1 (A) is a view for explaining a crowd of lights formed in a state in which an LED pick-up lamp is installed only on the left and right sides of a squid job vessel, and a portion intersecting between lights emitted from a pick-up is generated The light cluster 200 can not form a ring in which the light cluster 200 is integrally connected because the light cluster can not be formed in the forward and backward directions of the pick-

FIG. 1B is a view for explaining a crowd of lights formed in a state where an LED pick-up lamp is installed on front, rear, left, and right sides of a squid job ship so as to generate an intersection between lights emitted from a pick-up. 1 B is in the form of a ring of light bundles (200) connected in one piece)

However, FIG. 1 shows an LED that emits light toward the front of the pick-up lamp and an LED that emits light in the left and right directions of the pick-up, and an LED that emits light toward the rear of the pick- Is 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 has a portion intersecting the light emitted from the other pick-up.

At this time, the point where the light emitted from one of the picks or the like intersects with the light emitted from the other picks or the like intersects the point where the light cluster 200 is formed or between the light cluster 200 and the pick and place fixture 1 It is good.

In the case of using a conventional LED light fixture, since a gap between the LED light fixtures should be set very close to each other, a large number of light fixtures must be installed, which causes a problem of lowering the energy saving effect.

The structure of the LED mounting portion 10 is very important in order to solve such a problem and to stably form a bundle of light.

The LEDs 11a and 11b are provided on the LED mounting portion 10 so as to emit light in at least two directions out of the front, rear, left and right directions of the LED mounting portion 10, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c are provided, but intersections are generated between divergent lights.

More preferably, the LEDs are installed so as to generate light in the front, left, and right directions of the LED mounting portion 10, and to generate intersections between lights emitted from adjacent points.

Of course, the light is emitted in all four directions of front, rear, left, and right, but the diverging light intersects with the light emitted from the adjacent point, thereby drawing the shape of the ring which is intact in the lateral direction around the LED mounting portion 10 You can make it emit light.

This structure is easy to form a complete ring-shaped light cluster around the ear pick-up mount 1 even if an LED pick-up lamp is provided at the center of the pick-up mount 1. [

However, when the light is emitted only in the front, rear, left, and right directions of the LED installation portion 10, if the LED is swollen to the fixture (squid fishing vessel) due to the wave, a large change occurs in the light flux, The problem may be degraded.

In order to prevent this, LEDs 11a, 12a, and 13a that emit light toward relatively high points in the same direction among the four directions of front, rear, left, It is preferable that the LEDs 11c, 12c, and 13c that emit light toward the light emitting diodes are provided.

That is, in irradiating light in a specific direction, LEDs 11a, 12a, and 13a that emit light toward a relatively high point and LEDs 11c, 12c, and 13c that emit light toward a relatively low point are provided .

For example, an LED 11a that emits light in all directions of the pick-up and that emits light toward the upper side of the front and an LED 11c that emits light toward the lower side of the front.

In this case, even if the pinhole fixture 1 is swung by the waves, the crowd formed around the pinhole fixture can maintain the shape of the whole ring, so that the excellent picking effect can be maintained.

In addition, light irradiated toward a relatively low point reaches a deep water depth, inviting a deep-seated horoscope, and light irradiated toward a relatively high spot reaches a relatively low depth layer, So that the effect of picking up can be improved.

Of course, the light emitted from the LEDs 11c, 12c, and 13c, which diverge light toward the relatively low point, intersects with the light emitted from the LEDs 11a, 12a, and 13a that emit light toward the relatively high point The provision of the LEDs 11a, 11c, 12a, 12c, 13a, and 13c is more effective in maintaining the light clutter.

It is more preferable to irradiate light in three directions, that is, upward, middle, and lower, in irradiating light in a specific direction.

Of course, there is a need to create a point where the light intersects between the light that is emitted toward the upper portion and the light that is emitted toward the center portion, and the point where the light intersects between the light that is emitted toward the center portion and the light that is emitted toward the lower portion have.

As shown in the accompanying drawings, LEDs 11b, 12b, and 13b that emit light toward higher points than the LEDs 11a, 12a, and 13a that emit light toward a relatively high point are further provided .
