The present invention relates to a searchlight LED search lamp, and more specifically, by using an LED as a light source for a searchlight, the life span is prolonged by 30 times as compared with a searchlight halogen searchlight, It is possible to reduce the maintenance cost remarkably, and the light source of various colors can be provided for each color temperature. Therefore, it is possible to introduce various products into the searchlight LED searchlight .

서치라이트는 야간에 적의 항공기, 선박, 부대 등을 탐색하거나, 특정 지역이나 상대를 조명하기 위한 등화 장치이다.Searchlight is an equalizer that searches for enemy aircraft, ships, units, etc. at night and illuminates specific areas or opponents.

현재 주로 사용되고 있는 서치라이트는 램프형으로, 특정 지역이나 상대에게 빛이 지속적으로 조사된다. 이러한 서치라이트는 주로 할로겐 램프가 사용되고 있으며, 이러한 할로겐 램프는 석영관내에 텅스텐의 발광체가 전극에 연결되어 있고 램프내에는 불활성 가스 및 할로겐 화합물이 주입되어 있어, 텅스텐이 전원에 의하여 가열되게 되면 열과 빛을 발하면서 코팅된 반사면에 반사되어 빛이 발광되는 원리로 작동되게 된다.The searchlight, which is currently used mainly, is a lamp type, and light is constantly irradiated to a specific area or an opponent. Such a searchlight mainly uses a halogen lamp. In such a halogen lamp, a light emitting body of tungsten is connected to an electrode in a quartz tube, and an inert gas and a halogen compound are injected into the lamp. When tungsten is heated by a power source, And is reflected on the coated reflection surface to emit light.

이러한 서치라이트용 할로겐 램프는 대략 소비전력이 1,000W 이면, 예상수명이 1,000시간 정도이고 광도는 90만 cd 의 성능을 갖는다.Such a searchlight halogen lamp has a life expectancy of about 1,000 hours and a luminance of 900,000 cd / m 2 when the power consumption is about 1,000 W.

이러한 종래의 서치라이트용 할로겐 램프는 수명이 대단히 짧으므로 램프의 교체가 빈번하게 이루어져야 하므로 유지관리가 대단히 번거롭게 되고, 충격이 많이 발생되는 상황에서 사용되고 있으나 충격에 약하게 되어 내구수명이 더욱 짧아지게 되며, 특히 소비전력이 많게 되어 유지비용이 많이 들게 되는 문제점이 있었다. 또한, 할로겐 램프에서 발광되는 조명도 1 ~3개 정도의 종류로서 대단히 작으므로 제품의 선택의 여지가 없게 되는 것도 커다란 문제점으로 부각되고 있었다.
Such a halogen lamp for a conventional searchlight has a very short lifetime, so lamp replacement must be frequently performed, and maintenance is very troublesome and is used in a situation where a lot of impacts are generated. However, The power consumption is increased and the maintenance cost is increased. In addition, since the number of illuminations emitted from the halogen lamp is as small as one to three, there is no room for selection of products, which is a big problem.

본 발명의 목적은, 이러한 문제점을 해결하기 위한 것으로, 서치라이트의 광원으로 LED를 사용하게 되어, 할로겐 램프와 비교하여 수명이 30,000 시간 정도로 연장되어 30배의 수명이 연장되어 유지비용이 저렴하게 되며, 할로겐 램프에 비하여 충격에 강하게 되므로 해상에서 움직이는 선박에 사용되면 할로겐 램프에 비하여 내구수명이 더욱 연장되고, 거의 유사한 광도에서는 사용되는 전력이 아주 작아서 종래의 할로겐 램프에 비하여 약 15 ~ 20배의 사용전력이 절감되게 되며, 특히 다양한 색상의 광원의 사용이 가능하게 되어 다양한 신호의 조작이 가능하게 되어 다양한 용도로 사용이 가능한 서치라이트용 엘이디 탐조등을 제공하는 것이다.

Therefore, when used in marine vessels, the durability life is prolonged compared to halogen lamps, and the power used for almost similar luminosity is very small, which is about 15 to 20 times higher than conventional halogen lamps And it is an object of the present invention to provide a searchlight LED searchlight which can be used for various purposes by enabling various kinds of signals to be manipulated by enabling use of light sources of various colors.

본 발명의 이러한 목적은, 원통형으로 형성되며 일측이 개방된 서치라이트하우징과, 상기 서치라이트하우징의 내측의 저면에 배치된 엘이디어셈블리브라켓과, 상기 엘이디어셈블리브라켓의 LED램프고정구내에 고정된 복수의 엘이디램프가 설치된 본 발명에 따른 서치라이트용 엘이디 탐조등에 의하여 달성된다.

본 발명의 제1실시예에 따른 서치라이트용 엘이디 탐조등(A)은, 도 2 및 도 3에 도시된 바와 같이, 원통형으로 형성되며 일측이 개방된 서치라이트하우징(1)과, 상기 서치라이트하우징(1)의 내측의 저면에 배치된 엘이디어셈블리브라켓(4)과, 상기 엘이디어셈블리브라켓(4)의 LED램프고정구(41)내에 고정된 복수의 엘이디램프(5)가 설치되어 있다.As shown in Figs. 2 and 3, the searchlight LED search lamp 1 according to the first embodiment of the present invention includes a searchlight housing 1 formed into a cylindrical shape and open at one side, A plurality of LED lamps 5 fixed in the LED lamp fixture 41 of the LED assembly bracket 4 are provided on the inner bottom surface of the LED assembly bracket 4.

LED(Light Emitting Diode) 램프(5)는 전류가 P전극과 N전극에 공급되면서 정공과 전자가 활성층에서 결합하게 되면서 에너지 준위가 낮아짐과 동시에 낮아진 에너지 준위만큼 에너지가 빛의 형태로 발산되는 원리를 이용한 것으로서, 수명이 길고, 소비전력이 작게 들며, 회로가 간단하게 되고, 응답속도가 빠른 여러가지 장점이 있는 것이다.The LED (Light Emitting Diode) lamp 5 supplies a current to the P electrode and the N electrode. As the holes and electrons are coupled in the active layer, the energy level is lowered. At the same time, the energy is emitted in the form of light by the lower energy level. There are various advantages such as long life, low power consumption, simple circuit, and high response speed.

상기 서치라이트하우징(1)은 본 실시예에서는 금속 판재를 가공하여 원통형으로 형성되었으나, 이에 제한되는 것은 아니고, 육각 또는 팔각 등의 다른 형태로 제조가 가능하다고 할 것이다.In the present embodiment, the searchlight housing 1 is formed into a cylindrical shape by processing a metal plate material, but the present invention is not limited thereto and may be manufactured in other shapes such as a hexagonal or octagonal shape.

상기 엘이디어셈블리브라켓(4)은 서치라이트하우징(1)의 내측에 배치되며 복수의 LED램프(5)를 고정하기 위하여 벌집형태를 가지며, 본 실시예에서는 7개의 LED램프고정구(41)가 형성되어 있으나, 이에 제한되는 것은 아니고, 19개, 21개 등의 다른 갯수의 LED램프고정구(41)가 형성될 수가 있을 것이다.The LED assembly bracket 4 is disposed inside the searchlight housing 1 and has a honeycomb shape for fixing a plurality of LED lamps 5. In the present embodiment, seven LED lamp fixtures 41 are formed However, the present invention is not limited to this, and other numbers of LED lamp fixtures 41 such as 19, 21, etc. may be formed.

상기 LED램프(5)는, 도 4a,4b,4c에 도시된 바와 같이, 원통하우징(51)의 내측에 포물선반사경(52)이 형성되고 중앙의 연장대(53)상에 포물선반사경(52)을 향하게 LED(54)가 고정되어 있어, 직진성이 우수한 LED광선이 포물선반사경(52)상에 반사되어 반사율이 88%까지 향상되어, 광손실을 최소로 할 수 있는 구조를 갖게 되었다. 4A, 4B, and 4C, the LED lamp 5 includes a parabolic reflector 52 formed inside the cylindrical housing 51 and a parabolic reflector 52 formed on the central elbow 53, The LED 54 is fixed so as to face the parabolic reflector 52. The reflectance of the parabolic reflector 52 is improved up to 88% and the optical loss can be minimized.

이를 더욱 구체적으로 설명하면, 상기 LED램프(5)는, 도 5에 도시된 바와 같이, 원통하우징(51)과, 상기 원통하우징(51)의 내측에 고정되는 포물선반사경(52)은 그 저면에 스프링(52a)으로 지지되는 지지브라켓(52b)에 의하여 탄력있게 지지되며, 상기 포물선반사경(52)으로 면하게 고정된 LED(54)는 히트파이프(55)가 지나는 연장대(53)의 중앙에 고정되고,상기 연장대(53)의 저면에 고정된 LED(54)의 저면에는 PCB(54a)가 고정되어, LED(54)의 광손실을 최소로 하면서 LED(54)에 의하여 발생되는 열을 용이하게 히트파이프(55)를 통하여 배출할 수가 있는 구조가 제안되어 있다. 5, the LED lamp 5 includes a cylindrical housing 51 and a parabolic reflector 52 fixed to the inside of the cylindrical housing 51, The LED 54 fixed to the parabolic reflector 52 is fixed to the center of the extension base 53 through which the heat pipe 55 passes, and the LED 54 is held by the support bracket 52b supported by the spring 52a. A PCB 54a is fixed to the bottom surface of the LED 54 fixed to the bottom of the extension 53 to minimize the heat generated by the LED 54 while minimizing the light loss of the LED 54. [ So that the heat can be discharged through the heat pipe 55.

이와 같이 히트파이프(55)가 알루미늄재질의 연장대(53)상에 고정되어 있으므로 PCB(54a)에서 발생된 열이 히트파이프(55)와 연장대(53)를 통하여 원통하우징(51)으로 전달되면서 LED(54)에서 발생된 열이 용이하게 방출되게 되므로 LED(54)의 수명이 열에 의한 손상이 없이 사용될 수가 있게 되는 것이다.The heat generated from the PCB 54a is transmitted to the cylindrical housing 51 through the heat pipe 55 and the extension 53 because the heat pipe 55 is fixed on the extension 53 of aluminum The heat generated by the LEDs 54 is easily discharged, so that the life of the LEDs 54 can be used without being damaged by heat.

상기 지지브라켓(52b)에 의하여 포물선반사경(52)이 지지되며 흔들림에도 포물선반사경(52)의 내측에 설치된 LED(54)가 손상되지 않도록 스프링(52a)에 의하여 지지되어 충격이나 흔들림에도 손상이 되지 않는 구조를 갖는다. 상기 스프링(52a)의 내부에는 지지브라켓(52b)에 나사결합된 초점조절나사(52d)가 설치되어, 지지브라켓(52b)에 고정된 포물선반사경(52)의 LED(54)와의 촛점거리(L)를 초점조절나사(52d)의 회전에 의하여 조절할 수가 있게 되어, 원하는 촛점거리(L)를 설정할 수가 있게 되는 구조이며, 이와 같이 촛점거리가 중요한 이유는, 서치라이트용으로 사용되므로 필요에 따라 서치라이트에서 발광되는 빛을 멀리 보내기 위하여 모아주거나 가까이에 있는 물체를 확인하기 위하여 빛을 확산시킬 수 있게 촛점거리를 변경할 필요가 있으므로 중요하다고 할 수 있다.The parabolic reflector 52 is supported by the support bracket 52b and is supported by the spring 52a so as not to damage the LED 54 installed inside the parabolic reflector 52 even when it is shaken, . A focus adjusting screw 52d screwed to the support bracket 52b is provided in the spring 52a so that the focal length L of the parabolic reflector 52 fixed to the support bracket 52b Can be adjusted by the rotation of the focus adjusting screw 52d so that a desired focal length L can be set. The reason why the focal length is so important is that it is used for a searchlight, It can be said that it is important because it is necessary to change the focal distance so as to diffuse the light to collect the light emitted from the light, or to confirm the nearby object.

상기 포물선반사경(52)의 내측에는 은색의 반사층(52c)이 도금되어 있어, LED(54)에서 발광되는 빛을 반사하여 탐조등의 광도를 향상시킨다.A silver reflection layer 52c is plated on the inside of the parabolic reflector 52 to reflect the light emitted from the LED 54 to improve the brightness of the searchlight.

이와 같은 구조를 갖는 본 발명에 Heatpipe와 알루미늄 Bar를 적용하여 온도시험 시 표1과 같은 결과가 도시되어, LED의 방열이 효과적으로 진행된 것임을 알 수 있었다. In the present invention having such a structure, the heat pipe and the aluminum bar are applied, and the results shown in Table 1 are shown in the temperature test, indicating that the heat dissipation of the LED is effectively progressed.
