Description

The structure of discharge heat of LED fishing lamp in which the thermal performance is excellent by the liquid silicon oil and LED fishing lamp in which that is applied }

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to pickling and the like used to bring fish to a predetermined point to catch fish such as squid.

Light-loving fishes such as cutlass, sardines, and squids (hereafter called “hobitoseong”) are gathered in response to light and use light for fishing.

As a specific example, in the case of squid, a large amount of light bulbs are installed on the vessel and light is emitted at night to catch squid gathered around the vessel 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.

To solve this problem, LED pick-up lamps using LEDs (light emitting diodes-LEDs) as light emitters have been devised.

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 using the LED as the light emitting means such as the LED picking lamp.

In other words, the luminous efficiency of the LED is lower as the temperature increases, so it is very important to emit the heat generated from the LED quickly to the luminous efficiency of the LED.

For this reason, as shown in Korean Patent Application No. 10-2009-0119826, a structure such as a fishing vessel having a structure for quickly dissipating heat generated from the LED has been proposed, but the heat dissipation effect did not meet expectations.

On the other hand, LED pick-up lamp is very economical technology because the energy efficiency is very good, can considerably reduce the cost if only considering the consumption of energy for light emission.

However, in reality, the catch amount is greatly reduced in the vessel using the LED pick-up light, the situation is recognized that the LED pick-up light is not suitable for fishing for the tiger starfish.

For this reason, there was a problem that LED pick-up is not used.

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

The present invention is intended to solve the above problems, and more particularly, to provide a heat dissipation structure such as an LED picker, such as an LED picker, which is excellent in heat dissipation effect and excellent in energy efficiency as well as less damage of the LED module, and an LED picker applied thereto. .

In the present invention, by having the LED installation portion immersed in the liquid silicone oil filled in the case to ensure excellent heat dissipation effect such as LED pick up.

In addition, convection of the liquid silicon oil is generated by heating and cooling, and the convection phenomenon causes the silicon oil to flow from the lower part to the upper part through the inner flow hole of the LED installation part so that the heat dissipation effect is more excellent.

The LED heat sink structure of the present invention has a case filled with liquid silicone oil.

In addition, the LED is installed and has an LED installation portion installed so that the LED is immersed in the liquid silicone oil filled in the case.

The heat dissipation structure of the LED pick-up lamp of the present invention places the LED installation part in a case filled with liquid silicone oil having excellent heat transfer efficiency and electrical insulation, so that the LED is positioned so as to be immersed in the liquid silicone oil. Transmitted, the liquid silicone oil is quickly discharged heat to the outside, and excellent heat dissipation effect such as LED pick-up, there is a feature of less damage to the LED module.

In addition, in installing the LED in the LED installation part, it is possible to freely implement the light divergence angle such that it can be installed to emit light in 4 directions (360 ° direction around the pick-up light) before, after, left and right. have.

In addition, when the liquid silicone oil is filled in the case, when the space is formed to be formed in the case to prevent the occurrence of cracking of the case due to the expansion of the liquid silicone oil is characterized by excellent safety.

In addition, when the liquid silicone oil is allowed to flow from the bottom to the top along the flow hole formed in the LED mounting portion due to the convection of the liquid silicone oil, the heat of the LED mounting portion is more quickly transmitted to the liquid silicone oil. .

In addition, when the LEDs emitting light toward a relatively high point and the LEDs emitting light toward a relatively low point are installed in the same direction among the four directions of before, after, left, and right of the picking light, the picking effect is more effective. Excellent, there is a feature that can keep the picking effect stable.

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 has an object of providing a heat dissipation structure such as an LED pick-up light having excellent heat dissipation effect and excellent energy efficiency as well as less damage of the LED module and the LED pick-up light applied thereto.

In the course of various studies and experiments to achieve this purpose, the inventor of the present application paid attention to the liquid silicone oil (silicone oil).

Liquid silicone oils are characterized by heat transfer efficiency of hundreds to thousands of times of air and from tens to hundreds of times of water (pure).

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, it does not promote corrosion of metals such as aluminum and stainless steel, and has a characteristic that there is little change in viscosity due to changes in temperature.

Moreover, surface tension is very low compared with water, general synthetic oil, etc.

While applying the liquid silicone oil to a heat dissipation structure such as an LED pick-up, a structure in which the LED is immersed in the liquid silicon oil filled in the case for the purpose of the present invention was devised.

Therefore, the LED pick-up heat dissipation structure of this invention has the case 40 in which the liquid silicone oil 30 is filled.

In addition, LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c are provided, and the LEDs 11a, 11b, 11c, 12a, in the liquid silicone oil 30 filled in the case 40, 12b, 12c, 13a, 13b, and 13c have the LED installation part 10 installed so that it may be immersed.

The case 40 may be made of a transparent material so that light emitted from the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c may be smoothly emitted to the outside of the case 40.

In addition, the outside of the case 40 may be heat-exchanged with the outside air to quickly release heat to the outside.

The case 40 may be implemented with various materials such as synthetic resin or tempered glass, but may be implemented with a material having excellent heat transfer efficiency.

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

As described above, when the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c are immersed in liquid silicone oil, the LEDs 11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, The light emitted in 13c) spreads more widely than in the air.

That is, when irradiating the light of the LED in the air, the straightness of the light is strong, but the diffusion is weak.

However, when the LED is irradiated with light in the state of immersion in liquid silicone oil, the linearity of light is slightly reduced, but the light diffusivity is relatively improved.

In addition, even when the outside of the case 40 has a shape (such as a case of a normal incandescent light bulb) formed while forming a curved surface, the linearity of light emitted from the LED is somewhat lowered, but light diffusivity is relatively improved.

The diffusion of light in the LED pick-up lamp has a great influence on the formation of the light halo 200, which will be described later, and is very important for improving the pick-up effect.

When the liquid silicone oil is excessively heated to a predetermined temperature or more, the liquid silicone oil is expanded so that the liquid silicone oil is filled in the case 40 so that the liquid silicone oil is completely filled in the inner space of the case 40.

Therefore, when the liquid silicone oil is filled in the case 40, a space 42 is formed to be formed in the case 40 to prevent the case 40 from being broken due to expansion of the liquid silicone oil 30. It is good.

That is, when the liquid silicon oil is heated and expanded to a high temperature, the case 40 is prevented from being broken while being filled in the space 42 where the liquid silicon oil is not filled.

In consideration of the object of the present invention, it is preferable to widen the contact area of the LED installation unit 10 and the liquid silicone oil 30 described above.

However, in order to increase the contact area between the LED installation unit 10 and the liquid silicon oil 30, a structure such as excessive unevenness is formed in the LED installation unit 10 to hinder convection of the liquid silicon oil to reduce the heat radiation effect. cause.

That is, the heated silicon oil rises upward of the case 40, and when the cooling by heat dissipation is performed, the convection phenomenon that descends toward the LED installation unit 10 should be made smoothly so that the heat dissipation efficiency is excellent.

While the convection phenomenon is made smoothly, the flow hole 12 penetrated up and down may be formed in the LED installation unit 10 to widen the contact area with the liquid silicon oil.

That is, due to the convection of the liquid silicone oil 30, the liquid silicon oil 30 is formed in the LED installation part 10 so that the flow holes 12 penetrated up and down are formed to flow from the lower portion to the upper portion. will be.

Such a structure is more preferable for the structure in which the LED mounting portion 10 forms a column shape, in particular, the structure of the LED mounting portion 10 having a thick thickness.

In the present invention, the heat sink 20 for receiving the heat of the liquid silicon oil 30 to the outside of the case 40 to be discharged to the outside may be further improved to improve the heat dissipation effect.

The heat sink 20 may be implemented in various forms known in the art for heat dissipation.

However, since the temperature is higher in the upper portion of the case 40, the heat sink 20 may be positioned above the lower side of the case 40.

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

In addition, the structure of B of FIG. 4 is a structure in which a plurality of heat dissipation fins 21 are positioned above the case 40.

In addition, the structure of Figure 2 is a structure in which a plurality of heat dissipation fins 23 are located outside the cap-shaped body 22 located in the upper portion of the case 40, the heat dissipation performance is very excellent.

In the present invention, while being a point spaced downward from the lower end of the LED installation portion 10 of the case 40, the point forming the lower end of the case 40 protrudes downward to form a protruding portion 41 In this case, the convection phenomenon is made more smoothly.

That is, since the protrusion 41 has a lower temperature than other portions, the circulation of the liquid silicon oil 30 is more smoothly performed.

As in the present invention, the structure using the case 40 and the liquid silicone oil 30 has the LEDs left, right, and front of the LED installation part 10 because the portion for heat dissipation does not affect the installation angle of the LED. And, since it can be installed in any direction, there is a feature that can be implemented freely the light divergence angle.

That is, in installing the LEDs (11a, 11b, 11c, 12a, 12b, 12c, 13a, 13b, 13c) in the LED installation unit 10 can be installed to emit light in four directions: front, back, left, right The light divergence angle can be freely implemented.

Free implementation of the light divergence angle is very important when considering the formation of a halo described below.

By applying the heat dissipation structure of the present invention described above to implement the LED pick-up light can improve the energy efficiency of the pick-up light, it is possible to prevent damage to the LED module.

On the other hand, the energy saving effect in the fishing activities, such as the squid catch using the conventional LED pick-up, etc., but there was a problem that the catch amount does not reach significantly when using a conventional metal lamp.

However, for some reason, it has not been possible to determine whether catches are reduced in used fishing activities such as LED picking.

The inventors of the present application, after long research and efforts, LEDs, which emit light in the case of LED pick-up lamps, are excellent in the straightness of light, but have a low diffusivity. The result is that the light net can not be formed in the intact circle (the intact circle in the transverse direction) in that the intersecting light intersects each other to form a net shape and can trap coniferous fish. .

The locusts, such as squids, are gathered by the light and are not active in the area of strong light, but at the lower point of the relatively weak light fixture (ship) (the boundary between bright light and shadow and the light fixture) (ship) It is also known that it is mainly active in the area where shadows are formed.

It was judged that the predatory fishes themselves feed in places where they can hide, and plankton is more active in the boundary area between bright light and shadow, and in the shadow formation area by the light fixtures (1).

As a result, the frosted fish gathered by the light moves to the shadow formation area by the light and shadow boundary area and the fishing lamp installation (1), so that the feeding activity is carried out, and the halo is formed by a plurality of fishing lamps (200). If you put the fixtures on the inside and cannot be connected together, the picking effect is lowered.

In other words, if the halo is not formed or cannot be connected to one another, and partly broken halo is formed, the tiger fish gathered along the light are dissipated to the dark part outside the halo through the unconnected light and are dispersed. Sex fishes cannot be collected in a certain space (such as the area where shadows are generated by the light fixtures).

This results in less catches due to the small number of rosy fishes active at the bottom of the vessel where fishing is done.

FIG. 1A is a view for explaining a group of lights formed in a state where an LED pick-up lamp is installed only on the left and right sides of a squid catching vessel, but an intersection portion is generated between light emitted from the pick-up lamp. FIG. 1A Is not formed in the front and rear direction of the light fixture (1) because the light haul (200) does not form a ring completely connected to one)

FIG. 1B is a view for explaining a group of lights formed in a state where an LED pick-up lamp is installed at the front, rear, left, and right of the squid catching ship, but an intersection portion between light emitted from the pick-up lamp is generated. B of 1 is in the form of a ring in which the halo (200) is completely connected together)

However, FIG. 1 is provided with both LEDs emitting light toward the front of the lamp and LEDs emitting light in the left and right sides of the lamp, and LEDs emitting light to the rear of the lamp are not installed. If used.

In the structure of A of FIG. 1, the average catch amount was very small, and in the structure of B of FIG. 1, the average catch amount was more than the catch of A metal of FIG.

Therefore, it was found that it is very important to be able to form a bunch of light connected to the LED pick-up lamp using the LED of the light emitted is strong and the diffusion is weak.

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, the point at which the light emitted from one of the pick-up light and the light emitted from the other pick-up light intersects the point where the light bunch 200 is formed or the light bunch 200 and the pick-up lamp fixture 1 It is good.

In the case of using a conventional LED picking light, the distance between the LED picking light should be installed very close, so that a large number of picking lights should be installed, which has a problem of low energy saving effect.

The structure of the LED installation unit 10 is very important in order to solve this problem and to form a stable halo.

Preferred form of the LED mounting portion 10 to the LED mounting portion 10 to emit light in at least two or more directions of the front, rear, left, right four directions (360 divided into four equal directions) 11b, 11c, 12a, 12b, 12c, 13a, 13b, and 13c are provided in plural numbers, but are installed to generate an intersection point between the emitted light.

More preferably, the LED is installed to emit light in the front, left, and right directions of the LED installation unit 10 so that an intersection point is generated between the light emitted from adjacent points.

Of course, the light emitted in all four directions of the front, back, left, right, but the light emitted crosses the light emitted from the adjacent point to form the shape of a ring in the transverse direction around the LED installation unit 10 You can let them shine.

This structure is easy to form a whole ring-shaped light halo around the pick-up fixture 1 even if the LED pick-up lamp is installed in the center of the pick-up fixture 1.

However, if the light is emitted only in the front, rear, left, and right directions of the LED installation unit 10, when the squiggle occurs in the light fixture (squid catching vessel, etc.) due to the wave, a large change occurs in the halo, and the effect is picked up. Problems of deterioration may occur.

In order to prevent this, the LED installation unit 10 has a relatively low point with LEDs 11a, 12a, and 13a emitting light toward a relatively high point within the same direction among the four directions of before, after, left, and right of the pick-up lamp. LEDs 11c, 12c, and 13c which emit light toward the front side may be installed.

That is, LEDs 11a, 12a, and 13a for irradiating light toward a relatively high point and LEDs 11c, 12c, and 13c for radiating light toward a relatively low point are installed in irradiating light in a specific direction. To ensure that

For example, the LEDs 11a emit light in all directions of the pick-up lamp, and the LEDs 11c emit light in the downward direction of the front, and the LEDs 11c emit light in the downward direction of the front.

In this case, even if the picking-up fixture 1 is swung by the waves, the light halo formed around the picking-up fixture can maintain the shape of an intact ring and thus can maintain an excellent picking effect.

In addition, the light irradiated toward a relatively low point reaches a deep depth, and calls for a tiger-horned fish located in a deep position, and the light irradiated toward a relatively high point reaches a relatively low depth and forms a halo of light. As a result, the picking effect is improved.

Of course, the light emitted from the LEDs 11a, 12a, and 13a emitting light toward a relatively high point and the light emitted from the LEDs 11c, 12c, and 13c emitting light toward a relatively low point intersect. Installing LEDs 11a, 11c, 12a, 12c, 13a, and 13c has a better effect of maintaining the halo.

In irradiating light in a specific direction, it is more preferable to irradiate light in three directions of upper, middle and lower.

Of course, there is a need for a point where light crosses between the light emitted toward the top and the light emitted toward the center and a point where the light crosses between the light emitted toward the center and the light emitted toward the bottom. have.

As shown in the accompanying drawings, the LEDs 11b, 12b, and 13b for irradiating light toward a higher point than the LEDs 11a, 12a, and 13a for irradiating light toward a higher point are implemented. .
