일반적으로 다수의 LED를 이용한 LED 조명기구용 방열기 조명기구에 있어서는 이들 LED가 배치된 기판의 배면측. 즉 LED가 배치된 면의 반대측인 기판의 배면 측에 방열기가 배치되고 다시 방열기의 상측에 방열기로부터의 열을 외기로 방출하기 위한 팬이 배치되는 구조로 구성된다. 종래기술에 있어서, 일반적으로 알루미늄의 재질로 구성된 방열기의 형태는 중앙에 원통형 통공을 갖는 관상본체의 외면에 방사상으로 다수의 방열핀이 배치되어 있으며 관상본체의 원통형 통공내에 LED 기판으로부터의 열을 방열기측으로 효과적으로 전달하기 위한 동(銅)재질의 원주형 블록이 배치되어 있는 구조로 되어 있다. 이러한 종래기술의 방열기는 LED기판으로부터 발생되는 열을 방열시키는 기능을 발휘하지만 방열된 열을 외기로 방출하기 위한 별도의 수단으로서 LED 조명기구에는 송풍팬이 사용되었다. 그러나, 종래기술의 경우에 이러한 송풍팬이 사용되는 것이 유리한 경우가 있으나 송풍팬에 인가되는 전원이 어떠한 이유에서 차단되는 경우 LED 조명기구는 높은 열에 의하여 그 기능이 열화(劣化)될 수 있는 문제점이 있다. 따라서, 종래기술의 경우 송풍팬이 사용되는 것이 결코 유리한 것이라고는 할 수 없다.Generally in the radiator luminaire for LED lighting fixtures which used many LEDs, the back side of the board | substrate where these LEDs are arrange | positioned. That is, the radiator is arranged on the back side of the substrate opposite to the surface on which the LED is arranged, and a fan for dissipating heat from the radiator to the outside is disposed on the upper side of the radiator. In the prior art, the radiator, which is generally made of aluminum, has a plurality of radiating fins disposed radially on the outer surface of the tubular body having a cylindrical through hole, and heat from the LED substrate to the radiator side in the cylindrical through hole of the tubular body. It has a structure in which cylindrical blocks of copper material are arranged for effective transmission. The prior art radiator has a function of dissipating heat generated from the LED substrate, but a blower fan is used in the LED lighting device as a separate means for dissipating the radiated heat to the outside. However, in the case of the prior art, it is advantageous to use such a blower fan, but when the power applied to the blower fan is cut off for some reason, the LED luminaire has a problem that its function may be degraded by high heat. have. Therefore, in the prior art, it is never advantageous to use a blowing fan.

본 고안에 있어서는 종래의 이와 같은 점을 감안하여 안출한 것으로, 본 고안은 방열기의 외면에 방사상으로 다수가 배치된 방열핀을 통한 방열이 이루어질 수 있도록 함과 동시에 방열기의 관상본체내에 형성된 원통형 수직통로를 통한 굴뚝효과(stack effect)를 이용하여 상당부분의 열이 LED 조명기구의 외부로 방출될 수 있도록 한 LED 조명기구용 방열기를 제공하는데 그 목적이 있다.In the present invention is devised in view of such a conventional, the present invention is to enable the heat dissipation through the radiating fins are arranged radially on the outer surface of the radiator and at the same time the cylindrical vertical passage formed in the tubular body of the radiator It is an object of the present invention to provide a radiator for an LED luminaire that allows a significant amount of heat to be released to the outside of the LED luminaire by using a stack effect.

이를 위하여, 본 고안에 있어서는 투광렌즈를 갖는 조명기하우징내에 다수의 LED가 배열된 기판을 배치하고 외면에 다수의 방열핀이 배치되어 있으며 관상본체 내에 수직통공이 형성되어 있고 수직통공내의 하측에 동재질의 원주형 블록이 삽입되어 있는 방열기를 LED가 배열된 기판의 배면측에 배치한다. 방열기의 수직통공에 삽입된 원주형 블록의 상측부분에서 관상본체에 외부와 수직통로를 연통하는 수개의 급기공이 형성된다.To this end, in the present invention, a substrate in which a plurality of LEDs are arranged in an illuminator housing having a translucent lens, a plurality of heat dissipation fins are disposed on an outer surface thereof, a vertical through hole is formed in the tubular body, and the same material is formed under the inside of the vertical through hole. The radiator in which the columnar block is inserted is disposed on the back side of the substrate on which the LEDs are arranged. In the upper portion of the columnar block inserted into the vertical through hole of the radiator, a plurality of air supply holes are formed in the tubular body to communicate the outside with the vertical passage.

본 고안을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.

본 고안에 있어서 LED 조명기구는 투광렌즈(10)를 갖는 조명기하우징(12)내에 다수의 LED(14)가 배열된 기판(16)이 배치되고, 외면에 방사상으로 다수의 방열핀(18)이 배치되어 있으며 관상본체(20)내에 수직통공(22)이 형성되어 있고 수직통공(22)내의 하측에 동(銅)재질의 원주형 블록(24)이 삽입되어 있는 방열기(26)를 LED(14)가 배열된 기판(16)의 배면측에 배치된다.In the present invention, the LED luminaire has a substrate 16 in which a plurality of LEDs 14 are arranged in an illuminator housing 12 having a translucent lens 10, and a plurality of radiating fins 18 are disposed radially on an outer surface thereof. The LED 14 is provided with a heat sink 26 having a vertical through hole 22 formed in the tubular body 20 and a cylindrical block 24 made of copper material inserted into the bottom of the vertical through hole 22. Is arranged on the back side of the arranged substrate 16.

본 고안에 따라서, 방열기(26)에는 그 수직통공(22)에 삽입된 동재질의 원주형 블록(24)의 상측부분에서 관상본체(20)에 외부와 수직통로(22)를 연통하는 수개의 급기공(28)이 형성된다.According to the present invention, the heat dissipator 26 communicates the outside and the vertical passage 22 to the tubular body 20 at an upper portion of the same cylindrical columnar block 24 inserted into the vertical aperture 22. The air supply hole 28 is formed.

LED 조명기구가 점등될 때 조명등으로 사용되는 다수의 LED(14)는 점등과 함께 많은 열을 발생한다. 특히 이러한 열은 다수의 LED(14)가 배열된 기판(16)의 배면측으로부터 방열되는 것이 바람직하므로 다수의 LED(14)가 배열된 기판(16)의 배면에 동재질의 원주형 블록(24)의 저면측이 기판(16)의 배면측에 밀착될 수 있도록 방열기(26)가 배치된다. 다수의 LED(14)가 점등과 함께 많은 열을 발생할 때, 그 열은 주로 열전도율이 좋은 동재질의 원주형 블록(24)을 통하여 관상본체(20)에 전 달되고 이로부터 방사상 외측으로 연장되게 배열된 다수의 방열핀(18)에 의하여 방열기(26)의 외측 대기중에 방출된다. 이와 같은 방열핀(18)을 통한 방열과 함께 열은 관상본체(20)에 형성된 수직통공(22)을 통하여 방열되기도 하는 바, 본 고안에 따라서, 관상본체(20)에 외부와 수직통로(22)를 연통하는 수개의 급기공(28)에 의하여 이로부터 외기의 공기가 수직통로(22)측으로 급기되고 여기에서 방열에 의하여 가열된 공기가 수직통로(22)를 통한 굴뚝효과에 의하여 신속히 방출되어 방열효과가 크게 증가될 수 있는 것이다. 따라서, 본 고안은 종래에 별도로 열의 방출을 위한 별도의 송풍팬을 필요로 하지 않고 LED조명기구를 사용할 수 있도록 한다.When the LED luminaire is turned on, the plurality of LEDs 14 used as the luminaires generate a lot of heat together with the lighting. In particular, since the heat is preferably radiated from the back side of the substrate 16 on which the plurality of LEDs 14 are arranged, the columnar block 24 of the same material is formed on the back of the substrate 16 on which the plurality of LEDs 14 are arranged. The radiator 26 is arrange | positioned so that the bottom side of the () may be in close contact with the back side of the board | substrate 16. As shown in FIG. When a large number of LEDs 14 are turned on and generate a lot of heat, the heat is transmitted to the tubular body 20 through the same cylindrical columnar block 24 having good thermal conductivity and extending radially outward therefrom. A plurality of heat dissipation fins 18 arranged are discharged into the outer atmosphere of the heat dissipator 26. In addition to heat dissipation through the heat dissipation fins 18 as described above, heat is also dissipated through the vertical through holes 22 formed in the tubular body 20. Air from the outside air is supplied to the vertical passage 22 by several supply holes 28 communicating therewith, and the air heated by the heat dissipation is quickly released by the chimney effect through the vertical passage 22 to radiate heat. The effect can be greatly increased. Therefore, the present invention allows the use of LED lighting equipment without the need of a separate blower fan for the release of heat in the prior art.

이와 같이 본 고안은 방열기의 외면에 방사상으로 다수가 배치된 방열핀을 통한 방열이 이루어질 수 있도록 함과 동시에 방열기의 관상본체내에 형성된 원통형 수직통로를 통한 굴뚝효과를 이용하여 상당부분의 열이 LED 조명기구의 외부로 방출될 수 있도록 한 LED 조명기구용 방열기를 제공한다.As such, the present invention allows heat to be radiated through the radiating fins disposed radially on the outer surface of the radiator, and at the same time, a considerable portion of the heat is generated by using the chimney effect through the cylindrical vertical passage formed in the tubular body of the radiator. It provides a radiator for the LED lighting fixture to be emitted to the outside of the.
