본 발명은 투광 조명장치에 관한 것으로서, 더욱 상세하게는 투광 조명장치의 하우징 내부에 장착된 금속재의 인쇄 회로기판 상에 실장되는 복수개의 발광소자가 발광시 발생되는 열이 인쇄 회로기판 및 알루미늄 방열판으로 전도되어 발광소자가 과열되는 현상을 효율적으로 방지할 수 있으며, 렌즈 및 리플렉터를 통해 원하는 밝기의 빛을 눈부심이 방지된 상태로 조사할 수 있도록 한 것이다.The present invention relates to a floodlight apparatus, and more particularly, heat generated when a plurality of light emitting elements mounted on a printed circuit board of a metal mounted inside a housing of the floodlight apparatus is emitted to a printed circuit board and an aluminum heat sink. It can be effectively prevented from overheating the light emitting device, and through the lens and reflector to irradiate the light of the desired brightness in the state of preventing glare.

일반적으로, 투광 조명장치는 넓은 장소에 원하는 밝기의 빛을 조사하여 특정 구역을 밝게 비추어 주는 역할을 하기 위해 제작되는 조명 기구의 일종으로서, 야구장, 테니스장, 학교 운동장을 비롯하여 각종 경기장, 건물의 외곽 등에 설치하 여 사용함은 물론, 터널, 지하철 공사 현장의 지하 공간, 역이나 항만의 구내, 천장이 높은 중기계 공장 등의 경우에는 옥내에 설치하여 다양하게 사용되고 있으며, 그 광원으로는 주로 발광소자를 사용하고 있는 추세이다.In general, a floodlighting device is a kind of lighting equipment that is produced to illuminate a specific area by irradiating a light of desired brightness in a wide place, baseball field, tennis court, school playground, various stadiums, buildings, etc. In addition to installation and use, it is used indoors in tunnels, underground spaces of subway construction sites, premises of stations and harbors, heavy machinery factories with high ceilings, etc. The trend is.

상기한 발광소자(LED: light emitting diode, 또는 "발광 다이오드" 라고도 함)는 N형과 P형 반도체가 접합된 구조를 갖는 광전변환 반도체 소자인데, 이러한 발광소자는 적색, 청색, 황색 등으로 280~650nm 파장대의 전면 발광 또는 측면 발광의 고출력 발광소자로서 패키지화된 형태로 사용된다.The light emitting device (also referred to as a light emitting diode, or "light emitting diode") is a photoelectric conversion semiconductor device having a structure in which an N-type and a P-type semiconductor are bonded. Such light-emitting devices are red, blue, yellow, and the like. It is used in a packaged form as a high power light emitting device having a top emission or side emission of a wavelength band of 650 nm.

즉, 상기한 발광소자는 반도체의 P-N 접합 구조를 이용하여 주입된 소수 캐리어(전자 또는 양공)를 만들어 내고, 이들의 재결합에 의하여 발광되는 것으로, 반도체 발광소자는 크게 발광 다이오드(LED)와 레이저 다이오드(LD: laser diode)로 분류되며, 발광 다이오드나 레이저 다이오드는 처음부터 좁은 영역의 원하는 파장 대역만의 빛을 발생시키기 때문에 흑체 복사(blackbody radiation)를 이용하여 넓은 스펙트럼의 빛을 생성시킨 후 원하는 색깔의 필터를 사용하는 현재의 백열등 방식보다 그 효율이 매우 높고, 최소 50mW에서 최대 15W까지 이상 구동이 가능하며, 현저히 낮은 소비 전력에 비해 발광 효율이 좋은 편이고, 특히 사용 수명이 반영구적이어서 경제적이며, 렌즈 기술을 이용하여 가로등이나 터널 등과 같은 원거리 조사등에 적극적으로 활용할 수 있는 장점이 있다. That is, the light emitting device generates a minority carrier (electron or hole) injected using the PN junction structure of the semiconductor and emits light by recombination thereof. The semiconductor light emitting device is largely a light emitting diode (LED) and a laser diode. It is classified as a laser diode (LD), and since a light emitting diode or a laser diode generates light of a desired wavelength band in a narrow area from the beginning, it generates a broad spectrum of light using blackbody radiation, and then a desired color. Its efficiency is much higher than that of the current incandescent lamp using the filter, and it can drive at least 50mW up to 15W or more, and its luminous efficiency is good compared to the significantly lower power consumption. Technology can be used for long-range surveys such as streetlights and tunnels. There is an advantage.

한편, 종래의 투광 조명장치는 도 1a 내지 도 3에 도시한 바와 같이, 지지대(100)의 상단에 설치된 하우징(1)의 내부에 장착된 금속재의 인쇄 회로기판(3) 상부에 등간격으로 복수개의 발광소자(2)가 납땜에 의해 실장되고, 상기 인쇄 회로기판(3)의 하단부에는 상기 발광소자(2)가 발광함에 따라 인쇄 회로기판(3)으로 전도되는 열을 방열시키기 위한 알루미늄 방열판(4)이 등간격으로 복수개 설치되며, 상기 각각의 발광소자(2) 전방의 하우징(1)에는 각각의 발광소자(2)에서 발생되는 빛을 집광하여 조사하기 위한 렌즈(6)가 설치되어 구성된다.Meanwhile, as shown in FIGS. 1A to 3, the conventional floodlighting apparatus is provided with a plurality of equal intervals on the upper portion of the metal printed circuit board 3 mounted in the housing 1 installed on the upper end of the support 100. Two light emitting elements 2 are mounted by soldering, and an aluminum heat sink for radiating heat conducted to the printed circuit board 3 as the light emitting elements 2 emit light at the lower end of the printed circuit board 3. 4) A plurality of light emitting elements are provided at equal intervals, and the housing 1 in front of each light emitting element 2 is provided with a lens 6 for condensing and irradiating light generated from each light emitting element 2. do.

그러나, 이와 같은 종래의 투광 조명장치는 발광소자(2)의 발광에 의해 인쇄 회로기판(3) 및 알루미늄 방열판(4)으로 전도되는 열의 온도는 35~40℃를 초과하지 않도록 유지해야 만이 발광소자(2) 본래의 사용수명을 사용할 수 있으나, 실제 온도는 80~95℃를 유지하므로 인해 발광소자(2)의 사용 수명을 단축시키는 결과를 초래하게 되고, 이에 따른 발광소자(2)의 교체 비용이 많이 소요되는 문제점이 있었기 때문에 당업계에서는 발광소자(2)의 발광에 의해 인쇄 회로기판(3) 및 알루미늄 방열판(4)으로 전도되는 열의 온도가 35~40℃를 초과하지 않도록 유지할 수 있는 기술의 개발이 요망되었다.However, such a conventional floodlighting device must be maintained so that the temperature of heat conducted to the printed circuit board 3 and the aluminum heat sink 4 by light emission of the light emitting element 2 does not exceed 35 to 40 ° C. (2) The original service life can be used, but the actual temperature is maintained at 80 ~ 95 ℃ resulting in shortening the service life of the light emitting device (2), thereby replacing the cost of the light emitting device (2) Since there was a lot of problems, the art can maintain the temperature of the heat conducted to the printed circuit board 3 and the aluminum heat sink 4 by the light emission of the light emitting device 2 does not exceed 35 ~ 40 ℃ Development was desired.

또한, 종래의 투광 조명장치는 리플렉터(7)를 통해 반사하여 빛을 조사할 때 반사 면적이 작아 원하는 밝기의 빛을 효율적으로 조사하기가 어렵고, 렌즈(6)를 통해서 빛의 조사시 눈부심이 발생하는 경우가 빈번하므로 인해 원하는 밝기의 빛을 눈부심이 방지된 상태로 조사할 수 있는 장치의 출현이 요망되었다.In addition, the conventional floodlighting device is difficult to irradiate light with a desired brightness because the reflecting area is small when irradiating light by reflecting through the reflector 7, and glare occurs when irradiating light through the lens 6 Because of the frequent occasions, the emergence of a device capable of irradiating light of a desired brightness with anti-glare is desired.

따라서, 본 발명은 상기한 종래의 제반 문제점을 해결하기 위해 안출한 것으로서, 본 발명은 투광 조명장치의 하우징 내부에 장착된 금속재의 인쇄 회로기판 상에 실장되는 복수개의 발광소자가 발광시 발생되는 열이 인쇄 회로기판 및 알루미늄 방열판으로 전도되어 발광소자가 과열되는 현상을 효율적으로 방지할 수 있도록 하여 발광소자의 사용 수명을 크게 연장시킬 수 있을 뿐만 아니라, 이에 따른 장치의 유지 및 보수 비용을 절감시킬 수 있는 투광 조명장치를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the present invention is a heat generated when the plurality of light emitting devices mounted on the printed circuit board of the metal material mounted inside the housing of the floodlight apparatus By being conducted to the printed circuit board and the aluminum heat sink, it is possible to effectively prevent the light emitting device from overheating, thereby greatly extending the service life of the light emitting device, and thereby reducing the maintenance and repair costs of the device. The purpose is to provide a floodlighting device.
