Description

방출 광량비를 조절할 수 있는 엘이디 조명기구LED lighting fixtures with adjustable emission ratio
본 발명은 방출 광량비를 조절할 수 있는 엘이디 조명기구에 관한 것으로, 더 상세하게는 반사판의 형상 또는 위치에 따라 위치별 방출 광량의 비를 조정할 수 있는 위치별 방출 광량을 조절할 수 있는 엘이디 조명기구에 관한 것이다.The present invention relates to an LED lighting device that can adjust the emission light ratio, and more particularly to an LED lighting device that can adjust the amount of light emitted by location to adjust the ratio of the amount of light emitted by location according to the shape or position of the reflector. It is about.
일반적으로 기존의 광원 수단이 가지고 있는 고전력 소비, 짧은 수명 등의 문제점을 고려하여 엘이디를 광원으로 이용하는 조명장치들이 개발되고 있다. In general, lighting devices using LEDs as light sources have been developed in consideration of problems such as high power consumption and short lifespan of conventional light source means.
이러한 엘이디 광원을 이용하는 조명기구의 형태로는 기존의 백열전구 형태, 형광등 형태, 가로등 형태 등 기존의 조명기구의 형태와 크게 다르지 않다.The shape of the lighting fixture using the LED light source is not significantly different from the shape of the existing lighting fixtures such as the incandescent lamp form, fluorescent lamp form, street lamp form.
상기 열거된 형태의 조명기구들은 일측방향으로 광을 발산하는 구조를 가지는 것이 보통이며, 엘이디의 광방출면이 지면측을 향하도록 내부에 설치되는 구조가 대부분이다.The luminaires of the above-listed type usually have a structure that emits light in one direction, and most of the structures are installed inside so that the light emitting surface of the LED faces the ground side.
따라서 이러한 종래 엘이디 조명기구들은 광이 방출되는 지면 방향으로만 광이 방출되며, 그 반대의 방향으로는 광이 방출되지 않는 배광 특성을 나타낸다.Therefore, these conventional LED lighting fixtures exhibit light distribution characteristics in which light is emitted only in the direction of the ground where light is emitted and in the opposite direction.
이러한 예로는 공개특허 10-2013-0102276호(엘이디램프, 2013년 9월 17일 공개)를 포함하는 대부분의 백열전구 형태의 엘이디 조명장치가 해당된다. 즉, 본체체가 일측에 마련되고, 그 본체의 일면에 엘이디가 마련되고, 그 엘이디를 덮는 보호구가 덮이며, 그 보호구(덮개, 커버 등)를 통해 광이 발산되기 때문에 본체측으로는 광이 발산되지 않는 형태가 된다.Examples of such LED lighting apparatuses include most incandescent lamps, including Korean Patent Publication No. 10-2013-0102276 (LED lamp, published on September 17, 2013). That is, the main body is provided on one side, and an LED is provided on one surface of the main body, and a protective device covering the LED is covered, and light is emitted through the protective device (cover, cover, etc.), so that no light is emitted to the main body side. It does not form.
이러한 형태 외에 통상 공원 등의 실외에 조명과 심미감을 함께 줄 수 있는 구형 등 입체적인 형상 배광을 갖는 정원조명등 또는 공원조명등이 사용되고 있으며, 엘이디를 광원으로 하여 이러한 입체적인 형태의 정원조명등이나 공원조명등을 만들기 위해서는, 앞서 설명한 백열전구 형태의 엘이디 조명장치가 내부에 위치하며 외면이 구형 등의 커버를 더 추가 설치한 구성이 보통이다.In addition to these forms, a garden light or a park light having a three-dimensional shape light distribution such as a sphere that can provide lighting and aesthetics to the outdoors, such as a park, is commonly used. In addition, the above-described incandescent lamp-shaped LED lighting device is located inside, and the outer surface is usually a configuration in which the additional cover such as a sphere is additionally installed.
또한 비록 구형의 입체적인 배광을 하는 것은 아니며, 형광등 형태의 관형 조명장치이기는 하나 두 방향으로 광이 방출되는 엘이디 조명장치의 예로서, 등록특허 10-1039035호(엘이디 조명장치, 등록일자 2011년 5월 30일)를 들 수 있다.In addition, although it is not a spherical three-dimensional light distribution, as an example of the LED lighting device that emits light in two directions, although the tubular lighting device in the form of a fluorescent lamp, Patent No. 10-1039035 (LED lighting device, registered date May 2011 30 days).
등록특허 10-1039035호에 기재된 엘이디 조명장치는, 서로 반대방향으로 대응 설치된 복수개의 광원 어레이부를 두고, 각 방향으로 커버를 설치하여 두 방향으로의 배광이 이루어지도록 하며, 각 방향으로의 광량의 증감 제어를 전기적인 처리를 통해 수행하고 있다.The LED lighting apparatus described in Korean Patent No. 10-1039035 has a plurality of light source array units correspondingly installed in opposite directions, and covers are provided in each direction to distribute light in two directions, and increase or decrease the amount of light in each direction. Control is carried out via electrical treatment.
그러나 이러한 등록특허의 엘이디 조명장치는, 전기적인 처리를 통해 각 광원 어레이부의 광량을 제어할 수밖에 없으며, 이는 조명장치와는 별도로 광량 제어를 위한 수단을 구비해야 하는 문제점이 있었다.However, the LED lighting apparatus of this patent has no choice but to control the amount of light of each light source array unit through an electrical process, which has a problem of providing a means for controlling the amount of light separately from the lighting apparatus.
또한 각 광원 어레이부를 상면과 하면에 각각 설치하기 위하여 내부를 가로 방향으로 막는 방열부재를 사용하고 있기 때문에 각 방향으로 방출되는 광량의 비를 조절할 수 없으며, 각 방향의 방출 광량 만을 조절할 수 있어 불필요하게 많은 수의 엘이디가 설치되어 비용이 증가하게 되는 문제점이 있었다.In addition, since the heat radiating member which blocks the inside in the horizontal direction is used to install each light source array part on the upper and lower surfaces, it is impossible to adjust the ratio of the amount of light emitted in each direction, and only the amount of emitted light in each direction can be adjusted. There was a problem that a large number of LEDs are installed to increase the cost.
즉, 하부와 상부 각각에 1w 출력의 엘이디가 100개씩 설치된 것을 가정할 때, 상부측의 광량이 하부측 광량의 50% 수준으로 방출되도록 하기 위해서는, 실질적으로 상부측에는 50개의 엘이디만 설치해도 되지만, 상부측 광량과 하부측 광량이 같을 때에 대비하여 50개의 사용되지 않는 엘이디를 상부측에 더 설치해야 하는 것이다.That is, assuming that 100 LEDs of 1w output are installed in each of the lower and upper portions, in order to ensure that the light amount on the upper side is emitted at a level of 50% of the lower side light amount, only 50 LEDs may be installed on the upper side. 50 unused LEDs should be further installed on the upper side in case the upper and lower amounts of light are the same.
상기와 같은 문제점을 감안한 본 발명이 해결하고자 하는 과제는, 적어도 둘 이상의 광방출 방향을 가지며, 그 광방출 방향으로 방출되는 광량의 비를 제어할 수 있는 방출 광량비를 조절할 수 있는 엘이디 조명기구를 제공함에 있다.The problem to be solved by the present invention in view of the above problems, LED lighting device having at least two or more light emission direction, and can control the light emission ratio that can control the ratio of the amount of light emitted in the light emission direction In providing.
또한 본 발명이 해결하고자 하는 다른 과제는, 조명기구 자체에서 각 방향의 방출 광량비를 조절할 수 있는 엘이디 조명기구를 제공함에 있다.In addition, another object of the present invention is to provide an LED lighting device that can adjust the emission light ratio in each direction in the lighting device itself.

그러나 상기 프레임부(100)는 반드시 원형의 띠 형상일 필요가 없고 다각형 형상일 수 있으며, 이때에는 일반 피씨비를 사용할 수 있다.However, the frame part 100 may not necessarily have a circular band shape but may have a polygonal shape, in which case a general PC may be used.
상기 프레임부(100)의 상부와 하부에는 각각 제1커버부(200)와 제2커버부(300)가 결합된다. 상기 제1커버부(200)와 제2커버부(300)의 재질은 광을 전부 또는 일부 투과하는 수지재이며, 각각 프레임부(100)와 접하는 면에 결합단턱(210,310)이 마련되고, 그 결합단턱(210,310)에 체결공(211)이 마련되어 프레임부(100)에 볼트로 결합 될 수 있다.The first cover part 200 and the second cover part 300 are respectively coupled to the upper and lower portions of the frame part 100. The material of the first cover part 200 and the second cover part 300 is a resin material that transmits all or part of the light, and coupling steps 210 and 310 are provided on the surface contacting the frame part 100, respectively.

상기 방열핀(510)은 중심에서 방사방향으로 연장되게 구비되며, 그 높이는 제1커버(200)와 실질적으로 동일한 면에 위치하도록 마련된다. 즉, 상기 제1커버(200)가 구(sphere) 타입이므로 그 원주원주면 상에 위치하도록 구비되는 것이다. 상기와 같이 방열핀(510)이 방사방향으로 연장되고, 그 높이가 제1 커버(200)와 동일한 면에 위치하면 전원 공급부(500)에서 발생하는 열을 효과적으로 배출할 수 있으며 유려한 미관을 유지할 수 있는 장점이 있는 것이다.The heat dissipation fin 510 is provided to extend in the radial direction from the center, the height is provided to be located on the substantially same surface as the first cover 200. That is, since the first cover 200 is a sphere type, it is provided to be located on the circumferential circumferential surface thereof. As described above, when the heat dissipation fin 510 extends in the radial direction and the height thereof is positioned on the same surface as the first cover 200, the heat generated from the power supply unit 500 may be effectively discharged and a beautiful appearance may be maintained. There is an advantage.
상기 방열핀은 상기 제1 커버가 다면체 타입일 때도 동일하게 마련될 수 있음은 당업자에게 당연하게 유추될 것이다.It will be apparent to those skilled in the art that the heat dissipation fin may be provided in the same manner even when the first cover is a polyhedron type.
상기 차단판(520)의 중앙에는 연결봉(410)의 일단이 결합 되어 있으며, 그 연결봉(410)은 상기 제1커버부(200), 프레임부(100) 및 제2프레임부(300)에 의해 정의되는 내부 공간으로 하향 연장되어 있으며, 그 하부 끝단에는 반사부(400)의 중심이 결합 된다.One end of the connecting rod 410 is coupled to the center of the blocking plate 520, and the connecting rod 410 is formed by the first cover part 200, the frame part 100, and the second frame part 300. It extends downward into the defined internal space, the center of the reflector 400 is coupled to the lower end.
상기 반사부(400)의 형상은 전체적으로 원형의 구조를 가지는 며, 중심측보다 가장자리측이 높은 위치에 위치하도록 경사진 판이다. The reflector 400 has a circular shape as a whole and is inclined to be positioned at a position where the edge side is higher than the center side.
상기 반사부(400)는 상기 연결봉(410)의 하부 끝단이 결합 되는 결합구(420)와, 상기 결합구(420)가 중심에 위치하며 다수의 상하 통공(431)이 마련된 수평방향의 원판인 연결지지부(430)와, 상기 연결지지부(430)의 가장자리로부터 외측으로 연장되되 외측으로 갈수록 높이가 높아지도록 경사지며, 저면이 반사면 처리된 반사판(440)을 포함하여 구성된다.The reflector 400 is a horizontal circular plate provided with a coupling hole 420 to which the lower end of the connecting rod 410 is coupled, and the coupling hole 420 is located at the center thereof, and a plurality of upper and lower through holes 431 are provided.

도 4는 상기 반사부(400)의 단면 구성도이다.4 is a cross-sectional configuration diagram of the reflector 400.
도 4를 참조하면 상기 반사부(400)는 반사판(440)의 경사각(θ), 반사판(440)의 길이(L), 반사판(440)의 위치, 즉 도면상 상하방향 높이위치(H)에 따라 광원인 엘이디(LED)의 광을 반사시키는 정도에 차이가 발생하게 된다.Referring to FIG. 4, the reflector 400 may be disposed at an inclination angle θ of the reflector 440, a length L of the reflector 440, and a position of the reflector 440, that is, a vertical height position H in the drawing. Therefore, a difference occurs in the degree of reflecting the light of the LED (LED) as a light source.
상기 반사판(440)의 경사각(θ)과, 길이(L)의 성분은 반사부(400)를 제작할 당시에 결정되어 제작될 수 있다. 상기 반사부(400)는 엘이디(LED)에서 방출된 광을 하향으로 반사시키는 것이며, 따라서 반사부(400)에서 반사되는 광량을 조절하면 상기 제1커버부(200)를 통해 방출되는 상향의 광과 제2커버부(300)를 통해 방출되는 하향의 광의 광량을 조절할 수 있게 된다.The components of the inclination angle θ and the length L of the reflector 440 may be determined and manufactured at the time of manufacturing the reflector 400. The reflector 400 reflects the light emitted from the LED downward, and accordingly, when the amount of light reflected from the reflector 400 is adjusted, upward light emitted through the first cover part 200 is adjusted. And it is possible to adjust the amount of light of the downward light emitted through the second cover portion 300.
상기 반사판(440)의 높이 방향의 중앙부(C)와 엘이디(LED)의 위치의 차이에 따라 상향의 광량과 하향의 광량의 비율을 조절할 수 있게 되는데, 상기 중앙부(C)가 엘이디(LED)와 수평하게 위치할 때 하향의 광량이 가장 높으며, 그 높이(H)가 변화되어 높아지거나 낮아지는 경우에는 하향의 광량과 상향의 광량이 변화되어 광량비를 조절할 수 있게 된다.The ratio of the amount of light upward and the amount of light downward can be adjusted according to the difference between the position of the center portion C and the LED of the height direction of the reflector 440. The center portion C is connected to the LED. When the horizontal position is the highest amount of light downward, when the height (H) is changed to increase or decrease, the amount of light downward and the amount of upward light is changed to adjust the light quantity ratio.
상기 반사부(400)의 높이(H)를 조정하기 위해서는, 상기 연결봉(410)을 서로 길이가 다른 것으로 교체함으로써, 상기 제1커버부(200)와 제2커버부(300)를 통해 방출되는 상향과 하향의 광량비를 조절할 수 있게 된다.In order to adjust the height H of the reflector 400, the connecting rods 410 are replaced with ones having different lengths, thereby being discharged through the first cover part 200 and the second cover part 300. It is possible to adjust the ratio of the light up and down.
도 5는 본 발명의 다른 실시예에 따른 방출 광량비를 조절할 수 있는 엘이디 조명기구의 단면 구성도이다.Figure 5 is a cross-sectional configuration of the LED lighting fixture that can adjust the emission light ratio according to another embodiment of the present invention.
도 5를 참조하면 본 발명의 다른 실시예에 따른 방출 광량비를 조절할 수 있는 엘이디 조명기구는, 앞선 실시예에서의 연결봉(410)을 스크류축(450)으로 대체하되, 상기 스크류축(450)의 양단이 상기 차단판(520)과 상기 제2커버부(300)의 중앙하부에 아이들(idle) 상태로 회전 가능하게 고정되며, 상기 제2커버부(300)의 외측에서 상기 스크류축(450)의 하단에 결합 되어 그 스크류축(450)을 회전시킬 수 있는 손잡이부(460)를 포함한다.Referring to Figure 5 LED lighting fixture that can adjust the emission light ratio according to another embodiment of the present invention, replacing the connecting rod 410 in the previous embodiment with a screw shaft 450, the screw shaft 450 Both ends of the blocking plate 520 and the lower portion of the second cover portion 300 is rotatably fixed to the idle state (idle), the screw shaft 450 from the outside of the second cover portion 300 It is coupled to the bottom of the includes a handle portion 460 that can rotate the screw shaft 450.
또한, 상기 차단판(520)에 일단이 고정되어 하향으로 연장되어 상기 연결지지부(430)의 일부를 관통하여, 상기 스크류축(450)이 회전할 때 반사부(400)가 회전하지 않도록 지지하는 고정지지봉(470)을 포함하여 구성된다.In addition, one end is fixed to the blocking plate 520 and extends downward to penetrate a part of the connection support part 430 to support the reflector 400 not to rotate when the screw shaft 450 rotates. It is configured to include a fixed support rod (470).
이와 같은 구성에 의하여 상기 손잡이부(460)를 조작하여 스크류축(450)을 회전시키면, 그 회전방향과 회전정도에 따라 상기 반사부(400)의 높이와 정도를 조절할 수 있게 된다.By rotating the screw shaft 450 by operating the handle 460 by such a configuration, it is possible to adjust the height and degree of the reflecting portion 400 according to the rotation direction and degree of rotation.
따라서 앞서 설명한 연결봉(410)을 교체하지 않고도 설치 상태에서 상기 반사부(400)의 높이를 조절하여 상향과 하향의 광량비를 조절할 수 있게 된다.Therefore, it is possible to adjust the light amount ratio of the up and down by adjusting the height of the reflector 400 in the installation state without replacing the connecting rod 410 described above.
도 6은 본 발명의 다른 실시예에 따른 방출 광량비를 조절할 수 있는 엘이디 조명기구의 단면 구성도이다. 6 is a cross-sectional view of an LED lighting device that can adjust the emission light ratio according to another embodiment of the present invention.
도 6을 참조하면 본 발명의 다른 실시예에 따른 방출 광량비를 조절할 수 있는 엘이디 조명기구는, 상기 반사부(400)의 반사판(440)의 경사각(θ)을 조절할 수 있는 예를 나타낸다.Referring to FIG. 6, an LED lighting apparatus capable of adjusting the emission light quantity ratio according to another embodiment of the present invention shows an example in which the inclination angle θ of the reflector 440 of the reflector 400 may be adjusted.
상기 경사각(θ)이 45도를 중심으로 소정의 각도 범위 내에서, 상기 반사판(440)을 통해 하향으로 반사되는 엘이디(LED)의 광량이 가장 크며, 그 각도를 벗어난 경사각에서는 하향으로 반사되는 광량이 감소하게 된다. The inclination angle θ is the largest amount of light of the LED (LED) reflected downward through the reflecting plate 440 within a predetermined angle range around 45 degrees, the amount of light reflected downward at the inclination angle outside the angle This decreases.
따라서 상기 경사각(θ)을 조절하기 위해서 상기 반사판(440)을 부채모양의 분할판(441)으로 분할하고, 각 분할판(441)을 상기 연결지지부(430)에 제1힌지(442) 결합시키고, 스크류축(450)을 따라 상하로 이동할 수 있는 이동부재(480)를 상기 반사부(400)의 하부측의 스크류축(450)에 결합하고, 그 이동부재(480)에 일단이 제2힌지(483)에 의해 결합 되며, 타단이 상기 다수의 분할판(441) 중 하나에 제3힌지(482) 결합되는 다수의 각도조절축(481)을 포함하여 구성된다.Accordingly, in order to adjust the inclination angle θ, the reflecting plate 440 is divided into a fan-shaped partition plate 441, and each of the partition plates 441 is coupled to the connection support part 430 by the first hinge 442. In addition, the movable member 480 which is movable up and down along the screw shaft 450 is coupled to the screw shaft 450 at the lower side of the reflector 400, and one end of the movable member 480 is second hinged. 448, and the other end includes a plurality of angle adjusting shafts 481 coupled to one of the plurality of dividers 441 by a third hinge 482.
상기 스크류축(450)을 손잡이부(460)로 회전시키면 그 회전방향과 정도에 따라 상기 이동부재(480)가 상향 또는 하향으로 이동하게 되고, 그 이동에 따라 상기 각도조절축(481)의 경사각도가 변경되어, 상기 분할판(441)의 끝단측을 상기 스크류축(450)을 중심으로 모으거나, 반대로 멀어지는 방향으로 이동시켜 상기 경사각(θ)을 조절할 수 있게 된다.When the screw shaft 450 is rotated by the handle 460, the movable member 480 moves upward or downward in accordance with the rotation direction and the degree thereof, and according to the movement, the inclination angle of the angle adjusting shaft 481 is changed. As the degree is changed, the inclined angle θ can be adjusted by collecting the end side of the partition plate 441 around the screw shaft 450 or by moving in the direction away from the opposite side.
