첨부된 도면 도1 내지 도7을 참조로 본 발명의 실시예에 따른 방열 가로등을 설명한다.With reference to the accompanying drawings Figures 1 to 7 will be described a heat radiation street light according to an embodiment of the present invention.

도시된 바와 같이, 본 실시예에 따른 방열 가로등(100: 이하에서 설명의 편의를 위하여, 별다른 설명이 없는 한 '방열 가로등'은 간략히 '가로등'이라 한다)은 크게 커버(110), 방열 부재(130), 열 전달 부재(150), 기판부(170) 및 조광판(190)을 포함한다.As shown, the heat dissipation street lamp 100 according to the present embodiment 100 (for convenience of description below), unless otherwise stated, the 'heat dissipation street lamp' is briefly referred to as a 'street lamp', and the cover 110 and the heat dissipation member ( 130, a heat transfer member 150, a substrate unit 170, and a light control plate 190.

방열 부재(130)는 전체적으로 하부가 개방된 캡 형상을 갖는다. 방열 부재(130)의 상부 표면에는 다수의 방열핀(132)이 형성되고, 기판부(170)가 수용되기 위한 내부 공간(134)을 갖는다. 또한 방열 부재(130)는 정면 형상이 전체적으로 위가 좁은 사다리꼴 형상을 갖는 것이 바람직하다. 이와 같은 형상에 의해, 먼지와 같은 이물질이 방열 부재(130)에 쌓이는 것을 방지할 수 있다. 더불어, 발열 부재(130)는 이를 관통하는 다수의 방열홀(135)이 추가로 형성될 수 있다. 이에 의해 방열 부재(130)의 외부와 내부의 공기 흐름이 발생할 수 있어 효과적인 방열을 이룰 수 있다. 그러나 이와 같은 방열홀(135)은 커버(110)를 사용하지 않을 경우에는 형성되지 않을 수도 있음에 유의한다.The heat dissipation member 130 has a cap shape in which a lower portion thereof is opened. A plurality of heat dissipation fins 132 are formed on the upper surface of the heat dissipation member 130, and have an inner space 134 for accommodating the substrate unit 170. In addition, it is preferable that the heat dissipation member 130 has a trapezoidal shape having a narrow front shape as a whole. By such a shape, it is possible to prevent foreign matter such as dust from accumulating on the heat dissipation member 130. In addition, a plurality of heat dissipation holes 135 penetrating the heat generating member 130 may be further formed. As a result, air flows to the outside and the inside of the heat dissipation member 130 may occur, thereby achieving effective heat dissipation. However, it should be noted that such a heat dissipation hole 135 may not be formed when the cover 110 is not used.

열 전달 부재(150)는 기판부(170)와 방열 부재(130) 사이에 밀착하여 부착되어, 기판부(170)에서 발생된 열을 방열 부재(130)로 전달한다. 열 전달 부재(150)는 용도상 열 전도율이 높은 재질로 형성되는 것이 바람직하다. 또한 열 전달 부재(150)는 이를 관통하는 다수의 열 전달홀(152)이 추가로 형성되는 것이 바람직하다. 열 전달홀(152)은 공기의 흐름에 따른 열 전달 속도를 높여주는 기능을 담당한다. 더불어, 열 전달홀(152)은 금속으로 코팅되어 열전달 효율을 극대화할 수도 있다.The heat transfer member 150 is closely attached between the substrate unit 170 and the heat dissipation member 130 to transfer the heat generated from the substrate unit 170 to the heat dissipation member 130. The heat transfer member 150 is preferably formed of a material having high thermal conductivity for use. In addition, the heat transfer member 150 is preferably formed with a plurality of heat transfer holes 152 penetrating it. The heat transfer hole 152 serves to increase the heat transfer rate according to the flow of air. In addition, the heat transfer hole 152 may be coated with a metal to maximize the heat transfer efficiency.

기판부(170)는 기판(172)과 기판에 실장된 LED(174)를 포함하며, 방열 부재(130)의 저면에 열 전달 부재(150)를 경유하여 부착된다.The substrate unit 170 includes a substrate 172 and an LED 174 mounted on the substrate, and is attached to the bottom of the heat dissipation member 130 via the heat transfer member 150.

조광판(190)은 LED(174)의 종단이 삽입되는 LED 삽입홀(192)이 형성되고, 방열 부재(130)의 하부 개방부를 덮는다.The light control plate 190 is formed with an LED insertion hole 192 into which the end of the LED 174 is inserted, and covers the lower opening of the heat dissipation member 130.

커버(110)는 전체적으로 하부가 개방된 캡 형상을 갖고, 방열 부재(130)의 상부를 덮는다. 커버(110)는 정면에서 볼 때, 전체적으로 정면 단면의 형상이 위가 좁은 사다리꼴 형상을 갖는 것이 바람직하다. 이와 같은 형상은 커버(110)의 상부 표면에 먼지와 같은 이물질이 쌓이는 것을 방지하게 된다. 한편, 커버(110)의 형상은 사다리꼴에 반드시 한정될 필요는 없으며 필요에 따라 돔 형상을 가질 수도 있음에 유의한다. 커버(110)는 이를 관통하는 다수의 통기공(112)이 추가로 형성되어 방열 효과를 극대화할 수도 있다.The cover 110 has a cap shape in which a lower portion thereof is opened, and covers the upper portion of the heat dissipation member 130. When the cover 110 is viewed from the front, it is preferable that the shape of the front cross section as a whole has a trapezoidal shape with a narrow top. Such a shape prevents foreign matters such as dust from accumulating on the upper surface of the cover 110. On the other hand, the shape of the cover 110 is not necessarily limited to the trapezoid, it is noted that may have a dome shape as needed. The cover 110 may further be formed with a plurality of vent holes 112 penetrating the cover 110 to maximize the heat dissipation effect.

이와 같은 구성을 갖는 가로등(100)은 LED(174)에서 발생된 열이, 열전달 부재(150)를 통해 방열 부재(130)로 전달된다. 방열 부재(130)는 방열핀(132)을 통해 열을 방출하게 되며, 방출된 열은 커버(110)를 통해 외부로 배출되게 된다. 이에 의해 LED(174)의 동작이나 열 파손에 영향을 주는 열을 효과적으로 배출하게 된다.In the street light 100 having the above configuration, heat generated from the LED 174 is transmitted to the heat dissipation member 130 through the heat transfer member 150. The heat dissipation member 130 emits heat through the heat dissipation fins 132, and the released heat is discharged to the outside through the cover 110. This effectively discharges heat that affects the operation of the LED 174 or thermal breakage.
