| 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 on ‘modeling’ and ‘space 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’. |
