城市空間的照明在社會經濟發展與需求的精緻化下,城市的夜景成為塑造地方意象的關鍵性角色。而橋梁跨越區域隔閡,成為城市中連結各區的重要結構,也是地方的象徵與標記,而如何利用人工光源重塑城市獨特性格,已是城市光環境營造中重要的議題。本研究對透過夜間文化、照明設計概念與應用、以及橋梁結構美學之相關文獻歸納後,歸結出橋梁照明設計分析之重點項目,以此針對不同橋型照明設計案例之分析,歸納出橋梁照明設計考量之基本原則,並選擇高屏溪橋與高屏大橋作為模擬基地,根據上述原則與基地特性,擬定不同方案,模擬操作於實際基地上,做為未來橋梁照明設計之參考模型。根據文獻回顧之內容與多重個案分析之結果,以及模擬操作的過程,發展出一橋梁景觀照明設計流程,其由三大部分所構成:(1)環境與橋型的分析為基礎、(2)照明設計方案,並進一步進入、(3)橋梁景觀照明設計階段;而在橋梁景觀照明設計考量原則上,以技術性面向而言,須考慮(1)設計規範與法規、(2)眩光防治、(3)節能效益,以及(4)對生態與自然環境之影響,在美學面向上,則應考量(1)與周圍環境協調、(2)橋梁型態特徵表現、(3)照明設計重點選擇、(4)照明手法選用、(5)色彩搭配、(6)立體感的展現;橋梁景觀照明已成為基礎設施重要的附加價值,而未來橋梁景觀照明設計趨勢,將持續朝向節能、對生態友善的設計方向發展。
As the matter of fact, in the development of social and economic, the illumination of urban space is getting more refined, nightscape and the lighting in the urban space play a key role shaping the images of city. Bridges across the gap of the regions, they are not only the important structures to link the districts in city, but also a symbols and a marks of city. It become an important issue that how to use artificial light to reshape the unique character of the city. This study of reviewed the nightly life culture, the concept of lighting design and applications, and the aesthetics of the bridge structure, and then generalize the key items for analyzing the lighting design. Furthermore, using the key items to analysis different types of bridgescape lighting case, and summarized the principles of bridgescape lighting design. This study selects Kao-Ping-Hsi Cable-Stayed Bridge and Kao-ping Bridge as the simulation sites. Base on the lighting design principles and site’s characteristics as previously studied to development different programs and apply to the simulation sites. The result could be the reference of bridgescape lighting design model. According to literature review, the results of multi-case studies, and simulated operation process, developing a bridgescape lighting design process, which consists of three parts: (1) Environment and bridge-type analyzing (2) lighting design programs planning (3) bridgescape lighting design. For the technical aspect,, bridgescape lighting design need to consider (1 ) design guidelines and regulations (2) glare control (3) energy efficiency (4) the impact of ecology and the natural environment; for the aesthetical aspect, it should consider (1) coordination with the surrounding environment (2) the characteristics of the bridge type, (3) focal point selection of bridgescape lighting design (4) lighting skills used, (5) color (6) three-dimensional. Bridgescape lighting has became an important value-added, and future trends in bridgescape lighting design. Furthemore, it will development towards an energy conservation, ecological friendly design direction.
