Description

방열기능을 향상시킨 가로등{A STREET LIGHT ADVANCED ABILITY FOR EMITTINGTHERMAL ENERGY}Street light improved heat dissipation {A STREET LIGHT ADVANCED ABILITY FOR EMITTINGTHERMAL ENERGY}

본 발명은 밀폐구조를 갖는 가로등의 광원으로부터 발생한 열이 대기중으로 원활하게 방열되도록 함으로써, LED의 수명을 연장시키고 결과적으로 가로등의 수명을 연장시킬 수 있는 방열기능을 향상시킨 가로등에 관한 것이다.The present invention relates to a street lamp having an improved heat dissipation function that can extend the life of the LED and consequently extend the life of the LED by allowing the heat generated from the light source of the street light having the closed structure to be radiated smoothly to the atmosphere.

가로등은 밀폐구조를 갖도록 제조되며, 이는 가로등의 제작 방침에 따라 가로등 내부로 수분이나 먼지의 침투를 방지하도록 함으로써, 방수 기능과 먼지 차단기능을 높이기 위한 것이다.The street lamp is manufactured to have a sealed structure, which is to increase the waterproof function and the dust blocking function by preventing the penetration of moisture or dust into the street lamp according to the manufacturing policy of the street lamp.

이와 같이 제조되는 가로등은 상기한 방수기능과 먼지 차단기능이 높은 효과를 갖게 되나, 이와 달리 광원으로부터 발생된 열이 외부로 쉽게 빠져나가지 못하여 가로등이 열에 의해 장치 결함을 일으켜 쉽게 고장나는 다른 측면에서의 문제가 발생하여왔다.The street lamp manufactured as described above has a high effect of the above-described waterproofing function and dust shielding function, but in contrast, the heat generated from the light source cannot easily escape to the outside, so the street lamp causes a device defect due to heat, There has been a problem.

즉, 밀폐구조에 의한 가로등 내부 온도의 상승은 가로등의 빈번한 고장 원인으로 작용하게 되는 것으로, 이는 가로등의 내부장치를 구성하는 장치의 접합부의 용융에 의한 작동불능상태와, 90 ~ 120℃의 일정온도에 맞춰 사용 수명이 결정되어 있는 LED의 경우, 가로등 내부가 상기 온도를 훨씬 초과하는 온도를 유지함으로써, 가로등에 설치하는 LED의 경우 그 수명이 급격하게 떨어지는 문제가 있었다.In other words, the increase in the internal temperature of the street lamp due to the sealed structure causes a frequent failure of the street lamp, which is inoperable due to melting of the junction of the device constituting the internal device of the street lamp and a constant temperature of 90 to 120 ° C. In the case where the service life of the LED is determined in accordance with the above, since the inside of the street lamp maintains a temperature far exceeding the above temperature, there is a problem in that the life of the LED installed in the street lamp is sharply decreased.

가로등 내부의 온도상승 요인에 대해 다시한 번 살펴보면, 상기한 바와 같이, 가로등 내부의 광원으로부터 발생된 열이 외부로 원활하게 빠져나가지 못하는 요인과, 낮 동안에 햇볕 등 외부 광원으로부터 공급된 열이 가로등 내부에 머물러 쉽게 빠져나가지 못하는 요인에 의한다.Looking again at the temperature rise factor inside the street light, as described above, the heat generated from the light source inside the street lamp does not escape smoothly to the outside, and the heat supplied from the external light source such as sunlight during the day It is due to factors that do not stay out of it easily.

즉, 낮동안에 어느 정도의 열이 가로등 내부에 머물고 있는 상태에서 밤 동안에 가로등을 밝힘으로써, 광원으로부터 발생되는 열이 온도상승을 한층 가속화시킴으로써 LED를 사용을 위한 적합한 온도를 유지하기가 매우 어렵다는 문제가 있었다.That is, by lighting the street lamp during the night with a certain amount of heat staying inside the street lamp during the day, the heat generated from the light source accelerates the temperature rise further, so that it is very difficult to maintain the proper temperature for the use of the LED. there was.

결국, 가로등의 수명을 연장하고, LED의 사용수명을 연장시키기 위해서는 가로등 내부에 머물고 있는 열을 대기중으로 효율적으로 방열함으로써 가로등 내부의 온도를 낮추는 방법이 제시되어야 하며, 상기 온도를 낮추는 방법으로서는 가로등 내부로 강제대류시킴으로써 온도를 떨어뜨리는 것과, 방열판 설치를 고려해 볼 수 있다.As a result, in order to extend the life of the street lamp and to extend the service life of the LED, a method of lowering the temperature inside the street lamp by efficiently dissipating heat remaining inside the street lamp into the air should be proposed. Forced convection to reduce the temperature and consider the installation of a heat sink.

상기 강제대류에 의한 방법의 경우에는 별도의 강제대류 장치가 부가적으로 설치되어야 함으로써, 제조단가의 상승과 장치가 복잡해지는 또다른 문제를 야기함 으로써 그 실효성이 떨어지는 문제가 있다.In the case of the forced convection method, a separate forced convection device has to be additionally installed, resulting in an increase in manufacturing cost and another problem that the device becomes complicated, thereby lowering its effectiveness.

또한, 방열판의 설치의 경우에는 방열판 설치 자체만으로는 어느정도의 열이 방열되기는 하겠으나, 가로등의 경우 밀폐구조에 의해 방열이 용이하지 않다는 문제가 있다.In addition, in the case of the installation of the heat sink, the heat of the heat sink installation itself, but the heat to some extent, but in the case of the street lamp there is a problem that the heat radiation is not easy due to the sealed structure.

종래 가로등의 방열 구조를 살펴보면, 대한민국공개특허 2003-0005490호(2003.01.23.공개) '안정기 내장형 가로등 램프'에서는 방열판을 설치하고 있으나, 그 방열효과가 매우 낮은 구조를 가지고 있으며, 대한민국등록특허 10-0476464(2005.03.04.등록) '가로등 기구', 대한민국등록실용 20-0416181(2006.05.04.등록) '가로등의 등기구'에서는 방열구를 통해 열의 이동을 유도하고 있으나, 먼지 등의 출입가능성이 있어 부착적인 문제가 발생할 가능성이 높은 구조를 가지고 있다. Looking at the heat dissipation structure of a conventional street light, Korea Patent Publication No. 2003-0005490 (2003.01.23.) 'Battery-embedded street light lamp' is installed a heat sink, but the heat dissipation effect is very low, and Korea Republic Patent No. 10 -0476464 (registered on Apr. 2005.) 'Street lamp', Korea Registered Room 20-0416181 (registered on Apr. 2006, 2006) 'Street lamp' induces heat transfer through heat sink, but there is a possibility of entry of dust It has a structure that is likely to cause adhesion problems.

상기 문제를 해결하기 위해, 본 발명은 구조적으로 밀폐구조를 갖는 가로등의 내부의 열이 외부로 효율적으로 방열되도록 함으로써, 가로등 장치 내의 접합부의 고장에 의한 가로등 고장과, LED의 사용온도를 초과하는 사용온도에 의한 수명의 단축문제를 해결할 수 있는 방열기능을 향상시킨 가로등을 제공하는 것을 발명의 목적으로 한다.In order to solve the above problems, the present invention is to structurally close the heat of the interior of the street lamp having a sealed structure to efficiently radiate to the outside, the failure of the street lamp due to the failure of the junction in the street lamp device, the use exceeding the operating temperature of the LED It is an object of the present invention to provide a street lamp having an improved heat dissipation function that can solve the problem of shortening the life due to temperature.

상기 목적을 달성하기 위해, 본 발명은 직사각형 판형의 종방향 중앙부와, 상기 중앙부의 양측면에 연속되면서 각도를 달리하는 양측부와, 상기 중앙부의 상측면에 연속되면서 각도를 달리하는 상측부와, 상기 중앙부의 하측면과 연속되면서 각도를 달리하는 하측부로 이루어지며, 상기 상측부와 하측부에는 광원으로부터 방사되는 빛의 손실이 없도록 집광기능을 갖는 반사판이 설치된 광원케이스와,In order to achieve the above object, the present invention is a longitudinal central portion of the rectangular plate shape, both side portions that are different angles while being continuous on both sides of the central portion, the upper side portions that are different angles while being continuous to the upper surface of the central portion, and A light source case provided with a reflecting plate having a condensing function such that there is no loss of light emitted from the light source at the upper and lower parts, the lower part being continuous with the lower side of the center;

상기 광원케이스에 설치되는 광원으로부터 발생하는 열의 방열목적으로 상기 광원케이스의 배면에 인접하여 설치되는 방열부와,A heat dissipation unit installed adjacent to a rear surface of the light source case for a heat dissipation purpose of heat generated from a light source installed in the light source case;

상기 방열부에 인접하여 방열부의 열을 가로등의 외관케이스에 전달하기 위해 설치되는 메쉬망과,A mesh network adjacent to the heat radiating unit and installed to transfer heat of the heat radiating unit to the exterior case of the street lamp;

상기 광원케이스, 방열부, 메쉬망을 모두 내부에 수납하여 밀폐시키는 커버부로 이루어진 방열기능을 향상시킨 가로등을 주요 기술적 구성으로 한다.The light source case, the heat dissipation unit, and a street lamp having an improved heat dissipation function including a cover unit accommodating and sealing all of the inside is a main technical configuration.

그리고, 상기 방열부는 방열날개가 5 ~ 7㎜의 간격으로 40 ~ 100장이 포개져 형성된 것으로,The heat dissipation unit is formed by stacking 40 to 100 sheets of heat dissipation wings at intervals of 5 to 7 mm.

상기 방열날개는 두께 0.5 ~ 1.5mm이고 방열 표면적이 1장당 260 ~ 290㎠인 알루미늄으로서 2 ~ 3개의 골이 형성되고, 상기 골의 높이(h)는 13 ~ 15mm인 것으로, 상기 방열날개 간의 간격과 방열날개에 형성된 골에 의해 공기흐름(airflow)이 원활하도록 구성된 것이고,The heat dissipation blade is aluminum thickness of 0.5 ~ 1.5mm and the heat dissipation surface area of 260 ~ 290 ㎠ per sheet 2 to 3 bones are formed, the height (h) of the bone is 13 ~ 15mm, the interval between the heat dissipation wings It is configured to smooth air flow by the valley formed on the heat dissipation wing,

상기 메쉬망은 황동으로서, 방열부의 골에 수납되어 방열부의 열이 커버부에 전달되도록 상기 방열부와 커버부 덮개부와 접촉되도록 설치되는 것임을 특징으로 한다.The mesh net is brass, characterized in that it is accommodated in the valley of the heat dissipation unit is installed to be in contact with the heat dissipation unit and the cover part cover portion so that heat of the heat dissipation unit is transferred to the cover unit.

이상에서 살펴본 바와 같이, 본 발명에 따른 방열기능을 향상시킨 가로등은 가로등이 갖추어야 하는 구조적인 밀폐성을 유지하면서 가로등 내부에서 자체발생한 열과 외부의 광원으로부터 공급된 열에 의해 상승된 온도를 외부로 효율적으로 방열할 수 있는 구조를 가짐으로써 방열효과에 따른 가로등의 고장발생율을 최소화하고, LED의 사용수명을 최대한 연장시키는 효과를 갖는다.As described above, the street lamp having improved heat dissipation according to the present invention efficiently dissipates the temperature elevated by the heat generated from the inside of the street lamp and the heat supplied from the external light source while maintaining the structural sealing property of the street lamp. By having a structure that can minimize the failure rate of the street lamp according to the heat dissipation effect, it has the effect of extending the service life of the LED as much as possible.

그리고, 상기 방열효과는 방열판의 구조에 따른 공기의 흐름(airflow)이 원활하게 이루어지도록 하여 방열기능을 높이고, 방열판과 케이스를 연결하는 열전달 매개체로서 메쉬망에 의한 높은 방열기능을 가짐으로써, 효과적인 방열효과 구조를 갖고 있다.In addition, the heat dissipation effect is to increase the heat dissipation function by allowing the air flow (airflow) according to the structure of the heat dissipation smoothly, and has a high heat dissipation function by the mesh network as a heat transfer medium connecting the heat sink and the case, effective heat dissipation It has an effect structure.

이하, 상기 방열기능을 향상시킨 가로등의 기술 구성에 대해 도면을 통해 더욱 구체적으로 살펴보고자 한다.Hereinafter, the technical configuration of the street lamp having the improved heat dissipation function will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 가로등(1)의 외관을 보인 사시도로서, 케이스(40)에 의해 밀폐구조를 갖는 가로등을 보이고 있다. 상기와 같은 밀폐구조에 의해 가로등은 빗물 또는 먼지를 차단함으로써, 방수 및 먼지차단 기능에 의한 가로등의 고장을 예방할 수 있다. 그러나 이와 같은 고장 예방을 위한 밀폐구조는 앞서 살펴본 바와 같이, 광원에 의해 자체발생하는 열과, 외부의 광원, 태양으로부터 공급되는 열이 가로등의 내부에 머물어 온도상승을 유발함으로써, 가로등(1) 내부 부속간의 접착부위의 결함, LED의 사용온도를 초과함으로써, LED 사용수명의 단축문제를 가져온다.1 is a perspective view showing the appearance of a street lamp 1 according to the present invention, and shows a street lamp having a sealed structure by a case 40. By the sealed structure as described above, the street light blocks rainwater or dust, thereby preventing failure of the street light due to the waterproof and dust blocking function. However, as described above, the airtight structure for preventing the failure is that the heat generated by the light source, the external light source, and the heat supplied from the sun stay inside the street lamp to cause a temperature increase, thereby causing the inside of the street lamp 1 to be damaged. Defects in the adhesive area between parts and exceeding the LED's operating temperature lead to shortened LED service life.

도 2는 본 발명에 따른 광원케이스(10), 방열부(20), 메쉬망(30), 커버부(40)로 구성되는 가로등(1)의 내부구조를 보인 사시도로써, 가로등(1)의 밀폐구조에 의해 방열기능이 떨어지는 문제를 해결하기 위한 구조를 보이고 있다.Figure 2 is a perspective view showing the internal structure of the street light (1) consisting of a light source case 10, the heat dissipating unit 20, the mesh network 30, the cover 40 according to the present invention, The sealed structure has been shown to solve the problem of poor heat dissipation.

즉, LED 광원이 설치되는 광원케이스(10)로부터 발생된 열이 방열부(20)로 전달되고, 상기 방열부(20)의 열은 다시 메쉬망(30)을 통해 커버부(40)로 전달됨으로써 최종적으로 전달된 열이 대기중으로 방출될 수 있도록 한다.That is, heat generated from the light source case 10 in which the LED light source is installed is transferred to the heat dissipation unit 20, and the heat of the heat dissipation unit 20 is transferred to the cover unit 40 through the mesh network 30 again. This allows the finally delivered heat to be released into the atmosphere.

본 발명에서 중요한 기술적 구성은 상기 방열부(20)와 메쉬망(30)에 있으며, 상기 방열부(20)는 메쉬망(30)을 통해 열전달을 함과 동시에 공기흐름(airflow)을 원활하도록 구성되어 있어 방열기능이 뛰어나다.Important technical configuration in the present invention is in the heat dissipation unit 20 and the mesh network 30, the heat dissipation unit 20 is configured to facilitate the air flow (airflow) at the same time as the heat transfer through the mesh network (30). Excellent heat dissipation

도 3은 본 발명에 따른 방열부(20)를 보인 사시도로서, 상기 방열부(20)는 방열날개(21)가 5 ~ 7㎜의 간격으로 40 ~ 100장이 포개져 형성된 것으로, 상기 방열날개(21)는 두께 0.5 ~ 1.5mm이고 방열 표면적이 1장당 260 ~ 290㎠인 알루미늄으로서 2 ~ 3개의 골(211)이 형성되고, 상기 골의 높이(h)는 13 ~ 15mm인 것으로, 상기 방열날개(21) 간의 간격과 방열날개(21)에 형성된 골(211)에 의해 공기흐름(airflow)이 원활하도록 구성된다.3 is a perspective view showing a heat dissipation unit 20 according to the present invention, wherein the heat dissipation unit 20 is formed by overlapping the heat dissipation blade 21 with 40 to 100 sheets at intervals of 5 to 7 mm. 21) is a thickness of 0.5 ~ 1.5mm and the heat dissipation surface area of 260 ~ 290 ㎠ per sheet 2 to 3 bones 211 is formed, the height (h) of the bone is 13 to 15mm, the heat dissipation wing The gap between the 21 and the valley 211 formed in the heat dissipation blade 21 is configured to smooth the airflow (airflow).

상기 방열부(20)의 방열날개(21) 설치간격은 공기의 흐름을 고려하여 이루어지는 것으로, 5mm이 미만인 경우에는 설치간격이 너무 좁아 공기의 흐름을 방해하고, 열이 주변으로 분산되는 것을 방해하여 방열기능이 떨어지고, 7mm를 초과하게 되는 경우에는 공기흐름을 높일 수 있으나, 한정된 공간내에서 설치되는 방열날개의 설치 개수가 줄어들어 결과적으로 방열기능이 떨어지게 되므로, 상기 방열날개(21)의 설치간격은 5 ~ 7mm 간격을 유지한다.The installation interval of the heat dissipation blade 21 of the heat dissipation unit 20 is made in consideration of the flow of air, when less than 5mm, the installation interval is too narrow to hinder the flow of air, and to prevent the heat from dispersing to the surroundings. If the heat dissipation function is lowered and exceeds 7mm, the air flow can be increased, but the number of installation of the heat dissipation blades installed in the limited space is reduced, resulting in a decrease in heat dissipation function, the installation interval of the heat dissipation blade 21 is Maintain 5 to 7mm spacing.

그리고, 상기 방열날개(21)의 개수는 40장인 경우 LED 사용에 따른 가로등의 내부온도가 70℃까지 유지함으로써, LED 사용온도인 80 ~ 120℃의 범위에는 속하나 여전히 가로등 내부의 구성장치의 접속부 및 LED 사용수명에 영향을 줄 수 있으므로 40장 미만으로 사용하는 경우에는 열에 의한 가로등 고장 및 LED 사용수명이 떨어질 수 있고, 100장을 초과하게 되는 경우에는 방열기능이 뛰어나다는 장점을 갖는 대신 한정된 공간에서 설치 공간의 제한을 받고, 개수를 늘리기 위해 방열날개(21)간의 설치간격이 좁아지므로, 장수를 늘리것에 비해 방열효과가 그리 뛰어나지 않다는 문제가 있으므로, 방열효과 및 설치공간을 고려하여 40 ~ 100장 내에서 결정하여 설치하는 것이 바람직하다.In addition, when the number of the heat dissipation wings 21 is 40, the internal temperature of the street lamp according to the use of the LED is maintained at 70 ° C., but the connection part of the constituent device inside the street lamp still belongs to the range of 80 to 120 ° C. As it may affect the LED life span, when using less than 40 sheets, the street light failure and LED lifetime by heat may drop, and when it exceeds 100 sheets, it has the advantage of excellent heat dissipation. In order to limit the installation space and increase the number of installation intervals between the heat dissipation blades 21 are narrowed, there is a problem that the heat dissipation effect is not so excellent compared to the increase in the number of long, 40 ~ 100 pieces in consideration of the heat dissipation effect and installation space It is preferable to determine and install within.

그리고, 상기 방열날개(21)의 두께는 0.5 ~ 1.5mm로서, 0.5mm 미만인 경우에는 설치 및 가공이 용이하지 않고, 1.5mm를 초과하게 되는 경우에는 방열면적을 넓히는데 있어 비효율적이라는 문제가 있으므로, 상기 방열날개(21)의 두께는 0.5 ~ 1.5mm의 범위 내에서 결정하는 것이 바람직하다.And, the thickness of the heat dissipation blade 21 is 0.5 ~ 1.5mm, if less than 0.5mm, the installation and processing is not easy, if it exceeds 1.5mm, there is a problem that it is inefficient in widening the heat dissipation area, The thickness of the heat dissipation wing 21 is preferably determined within the range of 0.5 ~ 1.5mm.

상기 방열날개(21)의 표면적이 1장당 260 ~ 290㎠으로서, 알루미늄으로 이루어지며, 상기 방열날개(21)에는 2 ~ 3개의 골(211)이 형성된다.The surface area of the heat dissipation wing 21 is 260 ~ 290 ㎠ per sheet, made of aluminum, the heat dissipation wing 21 is formed with two to three valleys 211.

상기 골(211)의 높이(h)는 13 ~ 15mm로서, 상기 골(211)이 형성됨으로써, 메쉬망(30)의 수납공간을 제공함과 동시에 공기의 흐름이 원활하게 이루어질 수 있는 통로 역할을 하여 방열기능을 높여주게 된다. 상기 골(211)의 높이는 13mm 미만으로 하는 경우에는 골(211)을 통한 공기의 흐름공간이 협소해져 방열기능 및 메쉬망(30)의 수납공간이 협소해지고, 15mm를 초과하게 되는 경우에는 방열날개(21)의 표면적이 떨어질 수 있으므로, 상기 골(211)의 높이(h)는 13 ~ 15mm를 유지하는 것이 바람직하다.The height (h) of the bone 211 is 13 ~ 15mm, the bone 211 is formed, thereby providing a storage space of the mesh network 30 and at the same time serves as a passage that can smoothly flow air It will increase the heat dissipation function. When the height of the valley 211 is less than 13mm, the flow space of air through the valley 211 is narrowed, the heat dissipation function and the storage space of the mesh net 30 is narrowed, the heat dissipation wing when it exceeds 15mm Since the surface area of the 21 may drop, it is preferable that the height h of the valley 211 is maintained between 13 and 15 mm.

또한, 상기 방열날개(21)에 형성되는 골(211)의 개수의 경우에도, 공기의 흐름공간과 표면적을 고려하여 2 ~ 3개의 골(211)을 방열날개(21)에 형성한다.In addition, in the case of the number of the valleys 211 formed on the heat dissipation blade 21, two to three valleys 211 are formed on the heat dissipation wing 21 in consideration of the flow space and the surface area of the air.

상기 방열날개(21)는 99.00%이상의 순도를 갖는 알루미늄을 사용한다. 일반적으로 알루미늄은 부드러운 금속, 전성, 연성이 풍부하여 박이나 철사로 만들 수 있으며, 일반적인 알루미늄의 순도는 98.0 ~ 99.85%로서, 주요 불순물은 규소와 철 이다.The heat dissipation wing 21 uses aluminum having a purity of 99.00% or more. Generally, aluminum is soft metal, malleable and ductile, and can be made of foil or wire. The purity of general aluminum is 98.0 ~ 99.85%, and major impurities are silicon and iron.

그리고, 상기 방열날개(21)는 알루미늄의 순도에 따른 열전달 효과 높여 최종적인 방열효과를 높이기 위해 비중(20℃) 2.6986, 용융점(℃) 660.2, 비열(100℃)(cal/g ℃) 0.226, 잠열(cal/g) 96.4, 전기전도도(%) 69.94, 전기저항온도계수 0.00429인 것을 사용한다.In addition, the heat dissipation wing 21 has a specific gravity (20 ° C.) 2.6986, melting point (° C.) 660.2, specific heat (100 ° C.) (cal / g ° C.) 0.226, in order to increase the heat dissipation effect according to the purity of aluminum. Use latent heat (cal / g) 96.4, electrical conductivity (%) 69.94, and electrical resistance temperature coefficient of 0.00429.

상기 메쉬망(30)은 황동(brass)으로 이루어진 것으로서, 방열부(20)에 형성되어 있는 골에 수납되어 방열부(20)와 어느 한쪽이 인접하고, 다른 한쪽은 커버부(40)와 인접하여 방열부(20)의 열을 커버부(40)로 전달함으로써 보다 높은 효율이 방열효과를 갖게 된다.The mesh net 30 is made of brass and is housed in a valley formed in the heat dissipation unit 20 so that one side is adjacent to the heat dissipation unit 20, and the other side is adjacent to the cover unit 40. By transferring the heat of the heat dissipation unit 20 to the cover 40, the higher efficiency has a heat dissipation effect.

즉, 방열날개(21)가 40 ~ 100장이 포개져 형성된 방열부(20)에 의한 방열효과를 어느정도 기대할 수 있으나, 상기 메쉬망(30)을 설치함으로써 높은 열전달에 의한 방열효과를 기대할 수 있으며, 구체적으로 상기 방열부(20)만 설치한 경우에 비해 5 ~ 10℃ 가량의 온도하강 효과를 보인다. 상기 온도의 하강효과는 1℃의 하강에 의해서도 LED수명의 연장효과가 높고, 가로등의 고장율이 떨어지는 것을 감안한다면 높은 방열효과를 갖는 것임을 알 수 있다.That is, although the heat dissipation effect by the heat dissipation unit 20 formed by stacking 40 to 100 sheets of the heat dissipation wings 21 can be expected to some extent, the heat dissipation effect by high heat transfer can be expected by installing the mesh network 30, Specifically, it exhibits a temperature drop effect of about 5 to 10 ° C. compared with the case where only the heat dissipation unit 20 is installed. The lowering effect of the temperature can be seen that it has a high heat dissipation effect in consideration of the high extension of the LED life, and the failure rate of the street light is reduced even by the fall of 1 ℃.

그리고, 상기 메쉬망(30)은 황동(brass)에 의해 메쉬형태로 제작됨으로써, 공기의 흐름(airflow)에 따른 열전달효과를 저지하지 않으면서 열전달효과를 높일 수 있도록 구성된다.In addition, the mesh net 30 is manufactured in the form of a mesh by brass, and is configured to increase the heat transfer effect without inhibiting the heat transfer effect due to airflow.
