Abstract

This study aims to analyze the illumination effects of bridges across the Han River. For the purpose, 8 bridges were selected. Field survey and measurements were performed, and the physical values such as luminance, color temperature and chromaticity were measured by Radiant Imaging Prometric 1400 Color. The results of the study are as follows; (1) Metal halide lamp, sodium lamp and LED(Light Emitting Diode) of various colors, are used in illuminating the bridges and create color contrasts and color changing by color filters. (2) Luminance contrast of the illuminated bridges affects 'modeling' and 'spare sense' of bridges, and it might improve people's preference and impression. (3) Color temperature of the illuminated bridges is influenced by 'color of bridge', 'material of bridge' and, 'color temperature and color of light sources'. (4) 'Structure of bridges' and 'luminaires' influence on the physical feature of the bridges. Especially, illumination of the bridges shows resemblant patterns by 'structure of bridges'.

본 연구는 한강교량의 야간경관조명에 관한 조명연출효과를 분석하기 위해 한강교량 8곳을 대상으로 경관조명 현황을 조사하였다. 선행연구를 통해 교량의 경관조명에 있어서 중요한 조명학적물리량 평가요소로 '휘도대비', '색상', '색온도'를 선정하였다. 디지털 광학 계측기인 Radiant Imaging Prometric 1400에 의해 측정된 휘도 색온도 색도분포 등의 물리량 분석결과, '교량의 구조형식' 및 '조명광원'이 한강교량의 야간경관조명의 물리적 특징에 큰 영향을 미치는 요소로 나타났으며, 특히 '교량의 구조형식'에 따라 강조하는 경관조명의 패턴이 유사하게 나타났다.
