Description
본 발명은 다양한 방향으로 방출되는 등기구의 빛의 세기를 3차원적인 수치적으로 측정하기 위한 배광측정기에 관한 것으로, 더욱 구체적으로 설명하면, 등기구가 설치된 등기구의 빛을 반사시키는 반사경이 프레임의 양단부에 배치되어 등기구의 중심과 반사경의 중심이 같은 동심원의 궤적을 가지므로 회전직경이 작아지게 되어 건물내에 설치할 경우에 필요한 배광측정기의 가용공간의 높이를 상당히 낯출 수 있게되어 배광측정기의 설치비용이 월등히 절감되고 유지관리비용이 절감되는 배광측정기에 관한 것이다.The present invention relates to a light distribution measuring device for measuring the intensity of light of the luminaire emitted in various directions in three dimensions numerically, more specifically, the reflector reflecting the light of the luminaire is installed on both ends of the frame Since the center of the luminaire and the center of the reflector have the same concentric trajectory, the rotation diameter becomes smaller, and the height of the available space of the light distribution meter required for installation in the building can be considerably reduced, which greatly reduces the installation cost of the light distribution meter. The present invention relates to a light distribution measuring instrument that can reduce maintenance costs.
일반적으로, 종래의 배광측정기는, 도5a,5b에 도시된 바와 같이, 프레임(100)의 중앙에 반사경(101)이 회전가능하게 고정되고 프레임(100)의 일단에 등기구(102)가 부착된 부착팔(103)이 고정되어 등기구(102)에서 방출되는 빛을 반사경(101)에서 반사시켜 이를 조도센서(도시하지않음)에 입사시키는 구조로 되어 있어, 프레임(100)이 예를들면, 약 5도정도 회전한 후에 부착팔(103)이 수평으로 360도 회전을 하고, 다시 프레임(100)이 5도회전한 후에 부착팔(103)이 수평으로 360도 회전하고, 이러한 작동을 프레임(100)이 180도까지 회전할 때까지 반복하여 측정을 하는 방식이다. 본 명세서에서 사용되는 '등기구'라는 용어는 광원의 배광제어 및 광색조정, 분광분포의 변화와 같은 광학적 기능을 갖고, 이들 기능을 수행하기 위해 광원을 유지하고 보호하는 기계적 기능 및 전원에 접속하기 위해 필요한 부품이나 부속장치 예를들면, 램프, 반사판, 안정기등을 포함하는 비롯한 전기적 기능을 겸비한 조명기구를 의미한다. 상기 프레임(100)이 180도까지 회전만을 측정하는 이유는 대부분의 등기구가 대칭형상이기 때문이며 비대칭형상일 경우에는 360도까지 회전시켜 측정한다. 그러나, 이와 같은 종래의 배광측정기는 등기구(102)가부착된 부착팔(103)의 회전직경이 약 5미터 정도로 크게되어 건물의 바닥부분을 굴착하여 가용공간을 확보하거나 건물내에 설치할 경우 건물의 높이가 높게되어 설치비가 높게 되는 문제점이 있었다.In general, the conventional light distribution meter has a reflector 101 rotatably fixed to the center of the frame 100 and a luminaire 102 attached to one end of the frame 100, as shown in FIGS. 5A and 5B. Since the attachment arm 103 is fixed to reflect the light emitted from the luminaire 102 by the reflector 101 and enters it into an illuminance sensor (not shown), the frame 100 is, for example, After rotating about 5 degrees, the attachment arm 103 rotates 360 degrees horizontally, and after the frame 100 rotates 5 degrees, the attachment arm 103 rotates 360 degrees horizontally, and this operation is performed by the frame 100. The measurement is repeated until it rotates to 180 degrees. As used herein, the term 'luminaire' has optical functions such as light distribution control and light color adjustment of the light source, changes in the spectral distribution, and to access mechanical functions and power sources that maintain and protect the light source to perform these functions. Necessary components or accessories, for example, lamps, lamps, reflectors, ballasts, etc., including electrical equipment, including electrical features. The reason why the frame 100 only measures the rotation up to 180 degrees is that most of the luminaires are symmetrical, and in the case of the asymmetrical shape, the frame 100 is rotated up to 360 degrees. However, such a conventional light distribution measuring instrument has a rotation diameter of the attachment arm 103 to which the luminaire 102 is attached is increased to about 5 meters, so as to excavate the bottom part of the building to secure an available space or to install in the building. There was a problem that the installation cost is high.
또 다른 종래의 배광측정기로는, 도6a,6b에 도시된 바와 같이, 프레임(100)의 중앙에 등기구(102)가 배치되고 반사경(101)은 등기구(102)의 주위를 회전운동을 하는 구조로서, 이러한 배광측정기 역시 반사경(101)의 회전직경이 5미터정도로 크게 되어 건물내에 설치할 경우 건물의 높이가 높게되어 건물의 바닥부분을 굴착하여 가용공간을 확보하거나 건물의 높이를 높여 건축하여야 하므로 설치비가 높게 되는 문제점이 있었다.As another conventional light distribution meter, as shown in Figs. 6A and 6B, a luminaire 102 is disposed at the center of the frame 100 and the reflector 101 is configured to rotate around the luminaire 102. As such, the light distribution measuring instrument also has a rotational diameter of the reflector 101 is increased to about 5 meters, and when installed in the building, the height of the building becomes high, so that the floor space of the building is excavated to secure the available space or to increase the height of the building, so There was an issue that became high.
본 발명의 목적은 이러한 문제점을 해결하기 위한 것으로, 회전직경을 최소로 하여 협소한 공간에서도 사용이 가능하게 되어 설치비가 저렴하게 되고 유지관리비용이 저렴한 배광측정기를 제공하는 것이다.An object of the present invention is to solve this problem, it is possible to use in a narrow space with a minimum rotation diameter to provide a light distribution measuring instrument is low installation cost and low maintenance cost.
본 발명의 이러한 목적은 고정대의 상부에 설치된 제1구동모터, 상기 구동모터의 회전축에 회동가능하게 고정되고 일단에는 반사경이 부착되고 타단에는 측정될 등기구가 고정된 등기구고정팔이 장착된 회동프레임과, 상기 회동프레임에 고정된 등기구회동부의 구동축에 연결되어 회동가능하게 고정되며 일단에 등기구가 부착된 등기구고정팔로 구성된 본 발명에 따른 배광측정기에 의하여 달성된다.This object of the present invention is a first drive motor installed on the upper part of the fixing rod, the rotation frame is fixed to the rotating shaft of the drive motor and the reflector is attached to one end and the luminaire fixing arm is fixed to the luminaire to be measured at the other end, It is achieved by the light distribution measuring instrument according to the present invention, which is connected to the drive shaft of the luminaire rotating part which is fixed to the rotating frame, is rotatably fixed and has a luminaire fixing arm attached to one end thereof.

상기 제1구동모터(2)는 회동프레임(3)을 일정각도로 회동시킨다. 상기 등기구회동부(41)는 상기 회동프레임(3)의 회동에 대응하여 등기구고정팔(4)의 일단에 고정된 등기구(43)가 지면에 대하여 수평이 유지되도록 고정간(42)을 일정각도로 회동시킨다. 상기 등기구회동부(41)는 본실시예에서는 독립적으로 작동되는 구동모터가 사용되었으나, 상기 제1구동모터(2)에 의해 작동되도록 상기 제1구동모터(2)의 회전축(21)의 회전에 따라 연동되게 회동되도록 체인과 스프로켓으로 이루어진 수단이 등기구회동부(41)의 회전축(411)상에 설치되는 것도 본 발명에 속한다 할 것이다. 상기 제2구동모터(44)는 시험되는 등기구(43)를 수평으로 360도 회전시킨다.The first driving motor 2 rotates the rotation frame 3 at a predetermined angle. The luminaire pivoting portion 41 has a fixed interval 42 at a predetermined angle so that the luminaire 43 fixed to one end of the luminaire fixing arm 4 is kept horizontal with respect to the ground in response to the rotation of the pivot frame 3.

이와 같은 구성을 갖는 본 발명에 따른 배광측정기(A)의 작용효과를 이하에상세히 설명한다.The effect of the light distribution measuring device A according to the present invention having such a configuration will be described in detail below.
측정될 등기구(43)가 지그(441)에 고정되고 등기구고정팔(4)이 가장 높은 위치의 초기상태에서, 제1구동모터(2)가 구동되어 회동프레임(3)이 시계방향으로 5도로 회동되어 정지되고, 이와 동시에 회동프레임(3)과 함께 등기구고정팔(4)도 회동되므로 등기구회동부(41)가 반시계방향으로 구동되어 상기 등기구(43)가 수평으로 유지되도록 고정간(42)을 회동시킨다. 이와 같이 등기구(43)가 수평으로 유지된 상태에서 제2구동모터(44)가 360도 회전하여 등기구(43)가 360도로 회전한다. 이와같이 등기구(43)에서 발광된 빛은 반사경(5)을 통하여 조도센서(6)로 반사되고 조도센서(6)에서 감지된 수치는 컴퓨터(7)로 출력되어 이 위치에서의 조도가 기록되게 되는 것이다. 이 위치에서, 다시, 제1구동모터(2)가 구동되어 회동프레임(3)이 시계방향으로 5도로 회동되어 정지되고, 이와 동시에 회동프레임(3)과 함께 등기구고정팔(4)도 회동되므로 등기구회동부(41)가 반시계방향으로 구동되어 상기 등기구(43)가 수평으로 유지되도록 고정간(42)을 회동시킨다. 이와 같이 등기구(43)가 수평으로 유지된 상태에서 제2구동모터(44)가 360도 회전하여 등기구(43)가 360도로 회전하게 되는 동작을 반복하면서 회동프레임(3)이 180도로 회동될때까지 반복하여 회동프레임(3)이 180도 회동되면 각지점에서의 조도의 수치가 입체적으로 기록되는 것이다. 만일 등기구(43)가 비대칭형이면 회동프레임(3)이 360도까지 위와 같은 방법으로 작동되어 모든 지점에서의 등기구의 조도가 기록되게 되는 것이다.In the initial state in which the luminaire 43 to be measured is fixed to the jig 441 and the luminaire fixing arm 4 is in the highest position, the first drive motor 2 is driven so that the rotation frame 3 rotates 5 degrees clockwise. And stop, and at the same time, the luminaire fixing arm 4 also rotates together with the rotation frame 3 so that the luminaire pivoting portion 41 is driven counterclockwise so that the luminaire 43 is kept horizontal. Rotate As described above, the second driving motor 44 is rotated 360 degrees while the lamp 43 is kept horizontal, so that the lamp 43 is rotated 360 degrees. As such, the light emitted from the luminaire 43 is reflected by the illuminance sensor 6 through the reflector 5 and the numerical value detected by the illuminance sensor 6 is output to the computer 7 to record the illuminance at this position. will be. In this position, again, the first drive motor 2 is driven so that the rotation frame 3 is rotated 5 degrees clockwise to stop, and at the same time the luminaire fixing arm 4 is also rotated together with the rotation frame 3 The rotating part 41 is driven counterclockwise to rotate the fixing section 42 so that the luminaire 43 is kept horizontal. As described above, the second drive motor 44 rotates 360 degrees while the luminaire 43 is kept horizontal, and the rotation of the rotation frame 3 is rotated 180 degrees while repeating the operation in which the luminaire 43 rotates 360 degrees. When the rotation frame 3 is rotated 180 degrees repeatedly, the numerical value of illuminance at each point is recorded three-dimensionally. If the luminaire 43 is asymmetric, the rotation frame 3 is operated in the same way as above 360 degrees so that the illuminance of the luminaire at all points is recorded.
이상과 같이 본 발명의 배광측정기는 반사경과 등기구가 고정되는 등기구고정팔이 회동프레임상에서 제1구동모터의 회전축을 중심으로 동심원을 그리면서 회동되므로 그 회전직경이 2내지 3미터로 대폭적으로 축소되므로 협소한 공간에서도 사용이 가능하게 되어 공간의 활용도가 높게되어 능률적이며 건물의 지하를 굴착하거나 건물의 높이를 일부로 높일 필요가 없으므로 설치비가 저렴하게 되고 유지관리비용이 저렴하다는 효과가 있다.As described above, the light distribution measuring instrument of the present invention is rotated while drawing a concentric circle around the rotation axis of the first driving motor on the rotation frame, in which the reflector and the luminaire are fixed, so that the rotation diameter is greatly reduced to 2-3 meters. Since it can be used in one space, the utilization of the space is high, which is efficient and there is no need to excavate the basement of the building or to raise the height of the building partly, so the installation cost is low and the maintenance cost is low.
