본 발명은 방열 효율을 높인 내부순환로를 갖는 냉각모듈을 구비한 LED 램프에 관한 것으로써, 상세하게는 방사상으로 형성된 냉각핀의 안쪽에 유로를 형성하여 외부로부터 방열핀을 통과하는 공기의 흐름이 원활하게 함으로써 LED에서 발생된 열을 보다 빨리 냉각시킬 수 있게 한 내부순환로를 갖는 냉각모듈을 구비한 LED 램프에 관한 것이다. The present invention relates to an LED lamp having a cooling module having an internal circulation path to increase the heat dissipation efficiency, and more particularly, to form a flow path inside the radially formed cooling fins to smoothly flow air through the heat dissipation fins from the outside. The present invention relates to an LED lamp having a cooling module having an internal circulation path that enables cooling of heat generated in the LED more quickly.

통상적으로 터널, 가로등 등에 이용되는 램프는 조도가 상대적으로 높은 수은 램프, 할로겐 램프 등이 이용되고 있으며, 이러한 램프는 전력소비량이 많을 뿐만 아니라 수명이 짧아 유지 보수에 많은 비용이 소요되는 단점이 있다. In general, mercury lamps, halogen lamps, etc., which have relatively high illuminance, are used for tunnels, street lamps, and the like. These lamps have high power consumption and short lifespan, and thus have a high cost of maintenance.

이러한 단점을 개선하기 위해 개발된 램프로 LED(light emitted diode)를 이용한 램프가 많이 사용되고 있다. As a lamp developed to improve such a disadvantage, a lamp using a light emitting diode (LED) has been widely used.

그러나 이러한 LED 램프는 LED가 발광시 많은 양의 열이 발생되며, 이 열을 원활하게 방출할 수 없을 경우 LED의 수명이 상대적으로 단축되는 문제점을 가지고 있다.However, such an LED lamp has a problem in that a large amount of heat is generated when the LED emits light, and the life of the LED is relatively shortened when the heat cannot be emitted smoothly.

이러한 단점을 개선하기 위해 다양한 방열구조를 갖는 LED 램프가 있으며, 그 중 하나로 공개특허 제10-2008-0071812호가 있다. In order to improve this disadvantage there is an LED lamp having a variety of heat dissipation structure, there is one of them there is Patent Publication No. 10-2008-0071812.

이는 도 6에 도시한 바와 같이 다수의 방열핀(120)을 갖는 통체(110)의 일측에 LED모듈을 설치하여 구성된 것이다. This is configured by installing an LED module on one side of the cylinder 110 having a plurality of heat radiation fins 120 as shown in FIG.

이렇게 구성된 종래의 LED 램프의 방열구조는 방열핀(120)이 형성되어 있어 LED에서 발생된 열이 외부로 전달되는 면적은 넓힐 수 있으나 외부의 찬 공기가 통체(110)측으로 유입되지 못하는 단점이 있었다. The heat dissipation structure of the conventional LED lamp configured as described above has a disadvantage in that the heat dissipation fin 120 is formed so that the area where heat generated from the LED is transmitted to the outside can be widened, but external cold air does not flow into the cylinder 110 side.

즉, LED에서 발생된 열이 방열핀의 단부로 전달되어 외부로 발산되기는 하지만 통체 자체에는 외부의 찬공기가 접촉되지 못하여 통체의 일측 단부에 설치된 LED의 열을 충분히 냉각시킬 수 없는 단점이 있었다. That is, the heat generated from the LED is transmitted to the end of the heat radiation fins to be emitted to the outside, but there was a disadvantage that the cold air is not in contact with the cylinder itself to sufficiently cool the heat of the LED installed at one end of the cylinder.

본 발명은 상기와 같은 종래 기술의 문제점을 해소하기 위해 개발된 것으로써, 외부의 찬공기가 중앙 부분까지 순환하여 냉각핀의 외측 단부뿐만 아니라 전체적으로 고르게 냉각이 이루어질 수 있어 LED의 냉각 효율을 높인 내부순환로를 갖는 냉각모듈을 구비한 LED 램프를 제공함을 목적으로 한다. The present invention has been developed to solve the problems of the prior art as described above, the outside cold air is circulated to the center portion can be cooled evenly as well as the outer end of the cooling fin as a whole to increase the cooling efficiency of the LED An object of the present invention is to provide an LED lamp having a cooling module having a circulation path.

The present invention cuts a part of the inside of the cooling fins to form a circulation path through which external cold air can circulate, so that external cold air flows into the outer end of the cooling fins as well as the inside to cool the cooling fins evenly. There is an effect that can cool the heat more effectively.

또한, LED에 전원을 공급하는 전원 공급부의 내부에고 공기가 유입되어 순환할 수 있는 순환로를 형성하여 LED는 물론 램프 전체를 보다 쉰게 냉각시킬 수 있는 효과가 있다.

As shown in FIG. 5, the LED fixing plate 11 is provided with an LED module having a plurality of LEDs on the opposite side of the surface on which the cooling fins 12 are formed. It has the same structure as the LED module constituting the LED lamp.

상기 냉각모듈(1)의 일측에는 상기한 연결판(3)이 설치된다. One side of the cooling module 1 is provided with the connecting plate (3).

상기 연결판(3)은 도 2에 도시한 바와 같이, 원형 판체의 일측면 가장자리 부분에 전선커버(4)가 결합되는 결합날개(31)를 원통형으로 형성하고 상기 결합날개(31)에는 하나 이상의 통기홈(31a)이 형성되어 있어 전선커버(4)가 덮힌 상태에서 이 통기홈(31a)의 일부가 개방된 상태가 되어 외부의 공기가 전선커버(4)의 내부로 출입할 수 있게 된다. As shown in FIG. 2, the connecting plate 3 has a cylindrical coupling blade 31 to which the wire cover 4 is coupled to one side edge portion of the circular plate body, and has one or more coupling blades 31. A vent groove 31a is formed so that a part of the vent groove 31a is opened while the wire cover 4 is covered so that outside air can enter and exit the inside of the wire cover 4.

상기 냉각핀(12)들사이의 중앙 즉, LED고정판부(11)의 중앙에는 전선관통축부(11a)가 형성되어 있다. A wire through shaft portion 11a is formed in the center between the cooling fins 12, that is, in the center of the LED fixing plate 11.

상기 전선관통축부(11a)는 원통형으로 구성되어 있어 중앙을 관통하여 전선이 지나가며, 이렇게 전선관통축부(11a)의 중앙을 통과한 전선이 LED모듈까지 연장되어 LED의 발광에 필요한 전기를 공급하게 된다. The wire through shaft portion 11a is formed in a cylindrical shape so that the wire passes through the center, and the wire passing through the center of the wire through shaft portion 11a extends to the LED module to supply electricity for emitting light of the LED. do.

상기와 같이 LED고정판부(11)의 중앙에 전선관통축부(11a)가 형성되고 이를 중심으로 상기 냉각핀(12)들이 방사상으로 형성되며, 이렇게 형성된 냉각핀(12)들 중 하나 이상의 냉각핀(12)은 상기 전선관통축부(11a)의 외면과 분리되어 냉각핀(12)과 전선관통축부(11a) 사이에 내부순환로(12a)가 형성된다. As described above, the wire through shaft portion 11a is formed at the center of the LED fixing plate 11 and the cooling fins 12 are formed radially around the cooling fins 12. 12 is separated from an outer surface of the wire through shaft portion 11a to form an inner circulation path 12a between the cooling fin 12 and the wire through shaft portion 11a.

즉, 도 6에 도시한 바와 같이 냉각핀(12) 바깥쪽의 개방된 부분으로 유입된 회부의 찬공기가 상기 내부순환로(12a)를 통해 이웃하는 냉각핀(12)으로 흐르면서 전선관통축부(11a)도 냉각을 시키게 되며, 종래와 같이 내부가 막혔을 때 발생되는 내부의 공기압에 의해 외부의 찬공기가 냉각핀(12)들 사이의 안쪽으로 흐르는 것이 제한되는 것을 방지할 수 있게 된다. That is, as illustrated in FIG. 6, cold air of the first portion introduced into the open portion outside the cooling fin 12 flows to the adjacent cooling fin 12 through the inner circulation path 12a, and the wire through shaft portion 11a. ) Is also cooled, it is possible to prevent the outside cold air flows in between the cooling fins 12 by the internal air pressure generated when the inside is blocked as in the prior art.

상기와 같이 구성된 LED 램프는 상기 연결판(3)의 안쪽에 LED에 공급되는 전원을 변환하기 위한 변환수단이 설치되며, 이러한 변환수단에서도 열이 발생하게 된다. The LED lamp configured as described above is provided with conversion means for converting the power supplied to the LED inside the connecting plate (3), heat is also generated in such conversion means.

Accordingly, as described above, at least one vent groove 31a is formed in the coupling blade 31 formed in the connecting plate 3, so that the air introduced into the vent groove 31a can be easily discharged to the outside. In order to form the two or more ventilation grooves (31a).

또한, 통상의 LED 램프는 베이스(41)가 위를 향한 상태로 설치되는 경우가 많으며, 이렇게 설치된 상태에서 작동될 경우 LED에서 발생된 열과 변환수단에서 발생된 열을 위로 흐르게 되고 이렇게 위로 흐르는 열이 보다 용이하게 외부로 배출될 수 있게 하기 위해 상기 베이스(41)의 일측에도 통기홀(41a)을 형성하였다. In addition, a conventional LED lamp is often installed with the base 41 facing upwards, and when operated in this state, the heat generated by the LED and the heat generated by the conversion means flows upward, and the heat flowing upwards is In order to be more easily discharged to the outside, the vent hole 41a is formed at one side of the base 41.

이렇게 통기홀(41a)을 형성함으로써 변환수단에서 발생된 열은 통기홈(31a)을 통해 유입된 외부의 찬 공기에 의해 흡수되고 이렇게 열을 흡수한 공기는 통기홀(41a)을 통해 외부로 배출되게 된다. The heat generated by the conversion means by forming the vent hole (41a) is absorbed by the external cold air introduced through the vent groove (31a) and the air absorbed by the heat is discharged to the outside through the vent hole (41a) Will be.

이렇게 대류 형상으로 외부의 찬공기와 내부의 더운 공기가 순환되게 함으로써 변환수단에서 발생된 열을 보다 쉽게 냉강시킬 수 있게 된다. The convection shape allows the external cold air and the internal hot air to circulate, thereby making it easier to cool the heat generated by the conversion means.
