Abstract

The assessment of the light trespass in terms of light pollution is difficult due to the complexity of light environments. As a result, the light pollution research has examined the influences of light pollution using simulation program such as RELUX. However, there still exists a differences between the real measurement value and the simulation value for the light trespass. In this paper, we analyzed the light trespass using the RELUX simulation program, and compared results with real measurement values. In this study, the regions (Seoul, Incheon, etc.) were investigated regarding the light trespass for outdoor lighting. The survey of vertical illuminance was analyzed measuring point (more than 2 point) out the window that was expected to light trespass for the higher anticipated to illumination. The illuminational predicted values for the RELUX program were compared with maximum one. As a result of this study, the illuminational errors between the measurement values and predicted values for the simulation were examined from -0.97 lx to 0.65 lx except 2.08 lx and -7.70 lx. The light trespass was analyzed the higher by how much the located close to the height, length, width of the outdoor lighting for the window. For measuring predicted values using RELUX, it was not sufficiently considered in the simulation conditions because of environmental factors and investigator error etc. Limitations of this study include the limited number of measurements, and greater field data is required in future studies.

빛공해의 주택 침입광은 현장에서 여러 환경 요인에 의해 정확한 평가가 쉽지 않다. 그래서, 현장에서의 측정 어려움을 대신하여 빛공해의 영향을 파악하기 위하여 시뮬레이션 프로그램(Relux 등)을 이용하여 분석하였다. 그러나, 침입광에 대한 실제 측정값과 시뮬레이션을 통한 예측값은 여전히 차이점이 존재한다. 본 연구에서는, 옥외조명에 대한 침입광을 조사하기 위하여 서울, 인천 등 측정지점을 선정하였다. 조도 측정은 주택창면 중 연직면 조도가 높을 것으로 예상되는 창문 밖 창면 2지점 이상의 측정지점을 선정하여 측정하였다. Relux 프로그램을 이용하여 예측된 값 중 최대값을 실측값과 비교하였다. 그 결과, 침입광 실측값과 예측값의 오차는 -0.97~0.65 lx(최대값[2.08lx]과 최소값[-7.70lx] 제외) 조사되어졌다. 주택창면을 기준으로 도로조명의 설치위치 높이(H), 거리(L), 너비(W)가 가까이 위치될수록 침입광은 높아짐을 알 수 있었다. 상용조명해석 프로그램(Relux)을 사용하여 예측값을 측정하는데 있어서 주변 환경 요인과 측정자의 오차 등으로 인해 실측값과 다소 오차가 발생하였다. 본 연구에서는 측정수가 많지 않아 차후 연구에서 좀 더 많은 데이터를 이용하여 분석할 필요가 있다.
