社區戶外照明節能與綠色照明之研究

Outdoor Lighting and Energy Conservation with Green Lights Program in Residential Community

高效率、安全舒適、低光害的「綠色照明計畫」是當前照明規劃設計之目標，不僅能節約能源，同時也能降低夜間照明對整體環境的各種衝擊。然而過去台灣的戶外照明常有使用低效率燈具、或是燈具超量設計之情形，加上未有具體的戶外照明節能規範，故此部分有檢討改進的空間。本研究以住宅社區為研究對象，探討周邊道路照明與戶外活動廣場照明節能基準與設計建議。燈具設置之節能依據，以「照明功率密度（LPD）」做為主要評價對象；照明品質則以現行的路面輝度、照度與均齊度做為依據。而後透過電腦模擬得出各光源類型下，針對照明品質維護與節能效益提升之設置建議。本研究最終提出社區戶外照明LPD之建議基準值，可做為照明節能之評估依據，提升都市能源效益、維護夜間照明品質。

The Green Lights Program is aimed at lighting design with high energy efficiency, safe and safety. However, outdoor lighting in Taiwan is usually designed with low energy-efficient luminaires or over designed. Moreover, there is no suitable energy standard for outdoor lighting. To improve lighting environment and propose design suggestion of energy conservation, road lighting and outdoor lighting in community were chosen as the samples to evaluate lighting power density (LPD) and lighting quality such as illuminance, luminance and uniformity. The lighting simulation software DIALux was used to analyze lighting quality and energy efficiency with different lighting sources. The results not only supply LPD suggestion of energy conservation for community outdoor lighting plan, but also help improve urban energy efficiency and nighttime lighting environment.
