Description

먼지 방지 방열구조 및 반사용 코너큐브를 갖는 엘이디 조명등 반사갓 및 그 제조방법LED lamps with dust-proof heat dissipation structure and reflective corner cubes and manufacturing method thereof
본 발명은 발광다이오드를 이용한 조명등, 특히 통상의 형광등 콘센트에 용이하게 설치하여 사용할 수 있는 라인형 LED 조명등용 반사갓에 관한 것으로서 보다 구체적으로 방열판에 먼지가 쌓여서 방열 성능이 저하되는 것을 방지하는 먼지 방지 방열구조, 방열 효율을 향상시키기 위한 방열핀/열전도제 및 LED의 제한된 방사각에 의해 발생되는 얼룩현상을 방지하는 난반사 구조를 갖는 LED 조명등 반사갓에 관한 것이다.The present invention relates to a reflector for a line-type LED lamp that can be easily installed and used in a lighting lamp using a light emitting diode, in particular a conventional fluorescent lamp outlet, more specifically, dust-proof heat radiation to prevent the heat radiation performance is reduced by the accumulation of dust on the heat sink The present invention relates to an LED lamp reflector having a structure, a heat radiation fin / heat conductor for improving heat dissipation efficiency, and a diffuse reflection structure that prevents staining caused by a limited radiation angle of the LED.
최근 기존의 백열등, 형광등을 대신하여 LED를 사용한 조명을 사용하고자 하는 시도가 활발하게 이루어지고 있는데, LED 조명은 기존의 조명장치에 비하여 전력소비가 적고, 수명이 길며, 다양한 색을 만들어낼 수 있고, 형광등과 같은 점멸 현상이 없어 눈의 피로를 적게 할 수 있는 장점이 있다.Recently, there have been many attempts to use lighting using LEDs instead of conventional incandescent and fluorescent lamps. LED lighting has lower power consumption, longer life, and can produce various colors than conventional lighting devices. There is no flashing phenomenon such as fluorescent lamps, which can reduce eye fatigue.
또한, LED 조명등을 설치함에 있어서 추가로 발생 되는 비용을 줄이기 위하여, 기존에 사용하던 백열등이나 형광등과 그 규격이 동일하여 기존의 백열등 또는 형광등용 소켓에 직접 설치하여 사용할 수 있는 LED 램프들이 사용되고 있다.In addition, in order to reduce the additional costs incurred in installing the LED lamps, LED lamps that can be used directly installed in the existing incandescent lamps or fluorescent lamp sockets are used because the same standard as incandescent lamps or fluorescent lamps used.
LED 조명등의 경우 LED에서 발생 되는 열을 방출하는 것이 중요한데, LED에서 발생되는 열이 잘 방출되지 않으면 LED 및 구동회로가 손상되거나 고분자 재질의 커버가 열화 되는 등의 문제점이 있다.In the case of an LED lamp, it is important to emit heat generated from the LED. If the heat generated from the LED is not well emitted, the LED and the driving circuit may be damaged or the cover of the polymer material may be deteriorated.
종래의 형광등 소켓에 삽입이 가능한 라인형 LED 조명등의 경우를 살펴보면 도 1, 도 2 및 도 3에서 보는 바와 같이 길이 방향으로 다수의 LED가 형성된 장방형의 PCB 기판(102)이 반사판(106), 방열부(104)를 포함하는 반사갓(103)에 설치되고, 플라스틱 재질의 커버(107)가 반사 갓(103)에 형성된 결합부(105)에 결합되는 구성을 갖고 있다.Looking at the case of a line-type LED lamp that can be inserted into a conventional fluorescent lamp socket, as shown in Figures 1, 2 and 3 is a rectangular PCB substrate 102 formed with a plurality of LEDs in the longitudinal direction reflector plate 106, heat dissipation It is provided in the reflection shade 103 including the part 104, and has the structure which the cover 107 made of plastic is couple | bonded with the engaging part 105 formed in the reflection shade 103. As shown in FIG.
도 2에서 나타낸 종래의 LED 조명등 반사 갓의 경우 핀 형태의 방열부를 갖고 있어 공기와의 접촉 면적이 넓어지므로 방열 효율이 상대적으로 뛰어나나, 장기간 사용으로 핀들 사이의 홈에 먼지가 쌓이기 쉽고, 방열핀 사이에 쌓인 먼지는 잘 제거되지 아니하므로 이에 의해 방열 효율이 급격하게 저하되어 LED 및 구동회로의 고장 원인이 되는 단점이 있다.In the case of the reflective lamp shade of the conventional LED lamp shown in Figure 2 has a fin-shaped heat dissipation portion, the contact area with air is widened, so the heat dissipation efficiency is relatively good, dust is easily accumulated in the grooves between the fins with long-term use, Since the dust accumulated in the well is not removed by this, the heat radiation efficiency is sharply lowered there is a disadvantage that causes the failure of the LED and the driving circuit.
도 3에서 나타낸 종래의 LED 조명등 반사 갓의 경우 반원 형태의 방열부를 갖고 있어 방열핀들 사이의 홈에 먼지가 쌓이는 것이 방지되나 방열핀을 사용한 경우에 비하여 방열 효율 자체가 낮은 단점이 있다.The reflective lamp shade of the conventional LED lamp shown in FIG. 3 has a semicircular heat dissipation part to prevent dust from accumulating in the grooves between the heat dissipation fins, but has a disadvantage in that the heat dissipation efficiency itself is lower than that of the heat dissipation fins.
또한, LED의 특성상 그 방사각(α)이 100° 정도에 불과하고, LED가 길이방향으로 간헐적으로 배치되어 있기 때문에, LED의 수직방향 근처가 상대적으로 밝게 되는 얼룩 현상이 나타나게 되는데, 이는 360° 방향으로 광의 조사가 이루어지는 형광등에 비하여 불리한 점이다.In addition, since the radiation angle α is only about 100 ° due to the characteristics of the LED, and since the LEDs are intermittently disposed in the longitudinal direction, a phenomenon of being relatively bright near the vertical direction of the LED appears, which is 360 °. This is a disadvantage compared to a fluorescent lamp in which light is irradiated in the direction.

1. 라인형 LED 조명등 반사갓 및 이를 포함하는 라인형 LED 조명등 1. Line type LED lamp reflector and line type LED lamp including the same
도 4은 본 발명의 일실시예에 따른 라인형 LED 조명등 반사갓을 갖는 라인형 LED 조명등의 사시도이고, 도 5는 도 4에 개시된 라인형 LED 조명등의 단면도이다.4 is a perspective view of a line-type LED lamp having a line-shaped LED lamp reflector according to an embodiment of the present invention, Figure 5 is a cross-sectional view of the line-type LED lamp disclosed in FIG.
도 4 및 도 5를 참조하면 본 발명에 따른 라인형 LED 조명등(200)은 반사부(310), 방열부(320), 방열부를 덮는 돔부(330)를 포함하는 반사갓(300), 소켓에 삽입되어 전기접속이 이루어지는 단자(410)가 설치되는 전기접속부(400), 반사갓(300)의 반사부(310)에 설치되는 복수의 LED(500) 및 커버(600)로 구성된다.4 and 5, the line type LED lamp 200 according to the present invention includes a reflector 300, a heat radiation part 320, a reflection shade 300 including a dome part 330 covering the heat radiation part, and inserted into a socket. And an electrical connection portion 400 having a terminal 410 for electrical connection, and a plurality of LEDs 500 and a cover 600 installed at the reflection portion 310 of the reflection shade 300.
각 부분을 더욱 자세히 살펴보면, 도 6은 본발명에 따른 반사갓(300)에 LED(500)가 설치된 단면도를 나타낸다.Looking at each part in more detail, Figure 6 shows a cross-sectional view of the LED 500 is installed in the reflector 300 according to the present invention.
반사갓(300)은 알루미늄 인발가공에 의해 일체로 제조될 수 있으며 길이 방향으로 절단하여 소정의 규격에 맞는 크기를 갖도록 한다. 반사갓(300)은 반사부(310), 방열부(320), 돔부(330) 및 결합부(340)로 구성되는데, 반사부는 복수의 격벽(312)으로 구분되고, 격벽에 의해 구분된 각각의 반사부(310)에는 LED(500)가 설치된다.The reflector 300 may be integrally manufactured by aluminum drawing and cut in the longitudinal direction to have a size that meets a predetermined standard. The reflector 300 includes a reflector 310, a heat dissipation unit 320, a dome unit 330, and a coupling unit 340. The reflector is divided into a plurality of partition walls 312, each of which is separated by a partition wall. The reflector 310 is provided with an LED 500.
LED 조명등은 LED의 방사각(α)이 100° 정도에 불과하고, LED 가 길이방향으로 간헐적으로 배치되어 있기 때문에, LED의 수직방향 근처로 광이 집중되는 현상이 발생되는데, 본 발명의 반사부(310)는 격벽(312)에 의해 구분되어 복수로 설치되고, 각각의 반사부(310)에 LED가 설치됨으로서 넓은 범위로의 광 조사가 가능하게 된다. In the LED lamp, the emission angle α of the LED is only about 100 °, and since the LEDs are intermittently disposed in the longitudinal direction, light is concentrated around the vertical direction of the LED. The 310 is divided by the partition 312 and is provided in plurality, and the LEDs are installed in each of the reflecting portions 310 to enable light irradiation in a wide range.
반사갓의 방열부(320)는 방열 효율을 높이기 위하여 핀 형태로 구성되며 도 5에서는 직사각형 단면을 갖는 핀의 형태가 개시되어 있으나, 핀의 형태는 필요에 따라 자유롭게 선택할 수 있는 것이다.The heat dissipation unit 320 of the reflection shade is configured in the form of a fin to increase the heat dissipation efficiency, and the shape of the fin having a rectangular cross section is disclosed in FIG. 5, but the shape of the fin can be freely selected as necessary.
핀 형태의 방열부(320)는 방열 효율이 우수하나, 장기간 사용시 먼지가 쌓이게 되면 방열 효율이 저하되는 단점이 있다. 돔부(330)는 방열부(320)를 덮는 반원형태로 구성되어 방열부(320)에 먼지가 쌓이는 것을 방지하게 된다. Fin-shaped heat dissipation unit 320 has excellent heat dissipation efficiency, but has a disadvantage in that the heat dissipation efficiency is lowered when dust is accumulated during long-term use. The dome part 330 is formed in a semicircular shape covering the heat dissipation part 320 to prevent dust from accumulating on the heat dissipation part 320.
돔부(330)는 방열효율을 증대시키기 위하여 가능한 그 두께가 얇은 것이 바람직하다.The dome portion 330 is preferably as thin as possible in order to increase the heat radiation efficiency.
LED(500)는 모듈형태로 반사부(310)에 직접 설치될 수도 있고, 혹은 장방형의 인쇄회로기판(510) 상에 길이방향으로 복수개 설치되어 반사부에 결합될 수도 있는데, 반사부(310)와 LED 모듈 혹은 LED가 설치된 인쇄회로 기판 사이의 접촉면은 제조 공차에 의해 완전하게 접촉되기가 어렵고, 이에 의해 발생되는 공기층에 의해 방열부로의 열전달 효율이 떨어지게 된다.The LED 500 may be directly installed in the reflector 310 in the form of a module, or a plurality of LEDs 500 may be installed in the longitudinal direction on the rectangular printed circuit board 510 to be coupled to the reflector. The contact surface between the LED module or the printed circuit board on which the LED is installed is difficult to be completely contacted due to manufacturing tolerances, and the heat transfer efficiency to the heat dissipation portion is reduced by the air layer generated thereby.
반사부(310)와 LED 모듈 혹은 LED가 설치된 인쇄회로 기판의 접촉면 사이에 발생되는 공기층의 영향을 감소시키기 위하여 열전도제(311)가 도포되는 것이 바람직한데, 열전도제(311)은 써멀 그리스(Thermal Grease) 혹은 방열젤이 사용되며, 상기 접촉면 사이의 공기층을 메우는 유막층을 형성함으로써 열전달 효율을 향상시키게 된다.In order to reduce the influence of the air layer generated between the reflecting portion 310 and the contact surface of the LED module or the printed circuit board on which the LED is installed, it is preferable to apply a thermal conductive material 311. The thermal conductive material 311 is thermal grease (Thermal) Grease) or a heat dissipation gel is used, and the heat transfer efficiency is improved by forming an oil film layer filling the air layer between the contact surfaces.
도 7에는 반사부(310) 및/또는 격벽(312)에 큐브코너 형태의 자반사코너(313)가 형성된 구성이 도시되어 있다. 큐브코너 형태의 자반사코너(313)는 전체적으로 피라미드 형상의 사각뿔이 음각되어 형성되는 것으로서 통상의 엠보싱 공정 등에 의해 제조될 수 있다.FIG. 7 illustrates a configuration in which a reflection corner 313 having a cube corner shape is formed in the reflector 310 and / or the partition 312. The cube reflection type magnetic reflection corner 313 is formed by engraving a pyramid-shaped square pyramid as a whole, and may be manufactured by a conventional embossing process or the like.
도 8에 도시한 바와 같이 자반사코너는 입사광(314)을 자반사코너 내의 반사면에서 반사시키게 되는데, 자반사코너가 밀집되게 형성됨으로서 LED에서 방사된 광이 난반사 하게 되어 더욱 균일한 조명을 얻을 수 있게 된다. As shown in FIG. 8, the magnetic reflection corner reflects the incident light 314 at the reflection surface in the magnetic reflection corner. As the magnetic reflection corner is densely formed, the light emitted from the LED is diffusely reflected to obtain a more uniform illumination. It becomes possible.
반사부(310)에는 반사 효율을 향상시키기 위하여 추가적으로 도금 등에 의해 반사 코팅층(315)이 형성될 수도 있다.In order to improve reflection efficiency, the reflective part 310 may further include a reflective coating layer 315 by plating.
도 9에는 커버(600)가 개시되어 있는데, 커버는 단부에 형성된 결합돌기(610)가 반사갓의 결합부(340)에 끼워져 결합되게 되며 통상 플라스틱 재질로 제조된다. 커버에는 광확산을 위한 광확산층(620)이 추가적으로 형성되거나 혹은 커버의 플라스틱 재질 내에 광확산제(630)가 포함되도록 제조될 수도 있다.9, a cover 600 is disclosed. The cover is coupled to the coupling protrusion 610 formed at an end of the cover 340 of the reflection shade and is usually made of a plastic material. The light diffusion layer 620 for light diffusion may be additionally formed on the cover, or the light diffusion agent 630 may be included in the plastic material of the cover.
