本計畫研究目標為依據105年的計畫成果，選定動態畫面之眩光及閃爍2個為主要探討造成光污染感受的因子，並操控2類LED組合燈(LED八卦形燈、LED孔雀尾形燈)，以便調查及研析民眾對光污染影響民眾感受與認知的程度，並提出光污染相關防制對策建議。主要工作包括：（一）進行戶外民眾對組合燈等光污染源感受實驗，完成民眾光污染類型之感受程度之研析，（二）進行調查及實地驗證廣告招牌戶外量測方法，完成廣告招牌戶外量測指標及量測程序之研提，（三）參考國際光污染管制規範及我國現況，完成我國光污染源管理對策及改善建議。 本計畫於臺中中山醫大完成LED組合燈戶外人體感受實驗，募集20位受試者共完成4,320次實驗，分別選定臺北市及新竹市6處，完成戶外廣告招牌光源亮度及閃爍量測216次，摘譯整理完成2篇國際光污染規範及更新國際光污染規範對照表，並完成1份光污染防制及管理指引草案。 實驗結果與各項工作分析發現重點如下： 1. 戶外LED組合燈民眾感受實驗針對選定的光污染源LED組合燈(八卦形LED組合燈、孔雀尾形LED組合燈)，完成216次照度波形、216次閃爍，合計532次量測；光污染源人體感受舒適界線研究的實驗，問卷設計包括最大眩光和最大閃爍等2種光污染源人體感知，實驗操控因子為LED組合燈單一封裝亮度（3種亮度水準）、播放圖案周期（3種）、觀測距離(3種距離，10 m~40 m)和4種常見圖案類型。完成室外光污染源(八卦燈、孔雀燈)各 10位青壯年及10位中老年之最大眩光和最大閃爍等2種光污染源人體感受與認知實驗，共執行實驗次數4,320次。 2. 根據人體感受與認知實驗結果顯示，性別、年齡、圖案樣式、亮度、閃爍頻率強度與觀測距離等因子對於眩光與閃爍主觀評價均有顯著影響( p<0.01)，女性對眩光與閃爍不適反應顯著高於男性，青壯年對八卦燈之眩光與閃爍不適高於中老年受測者，但對孔雀燈之眩光與閃爍不適反應則低於中老年受測者；實驗亦發現，近觀測距離、高亮度與高閃爍頻率強度有顯著的眩光與閃爍不適情形，但各主因子間之交互作用對於眩光與閃爍值主觀評價則無顯著影響。 3. 閃爍評價模型的分析上，引入新的評價指標因子，包含閃爍指數或頻率強度最大對比度，來提高閃爍評價指數的準確度，同時提出適當的眩光舒適區域建議表。本計畫後續將導入戶外量測數據來持續修正閃爍模型參數。 4. 完成戶外量測實驗，於臺北市及新竹市共有6處廣告招牌，於3時段(19:00 ~20:30、20:31 ~22:00、及22:01以後)，進行12項量測作業 (最大亮度、平均亮度、最小亮度、最大垂直照度、平均垂直照度、最小垂直照度、最大水平照度、平均水平照度、最小水平照度、亮度監測、垂直照度監測、閃爍)，合計量測實驗總次數為216次。 5. 完成廣告招牌及路燈之光污染量測方式，分別為亮度、垂直照度、眩光亮度、LED多媒體閃爍、LED組合燈閃爍等5種量測方式，其中垂直照度量測方式適用於路燈之光侵擾評估。 6. 國際間光污染管制規範研析，本年度新增南韓「以光污染防治為目標之廣告照明設置管理建議基準」及「以光污染防治為目標之裝飾照明設置管理建議基準」等規範解析，並更新國際法規分析表。

Based on results of 2016 EPA light pollution project, this research chose two kinds of LED combo lightsincluded peacock-tail-shaped lamp and octagon-shaped lamp, and studied the impacts of perceived glare and flicker of citizen in Taiwan. Furthermore this report the recommendations of the prevention and the regulations for light pollution. The main tasks include: (1) to perform experiments of subjective perception testsfor glare and flicker at night to build up the borderline between comfort and discomfort (BCD) for both LED combo light sources in the outdoor environment; (2) to conduct field surveys and prove measurement methods of outdoor advertising signs to propose the standard operation procedures; (3) to propose predictive improvement and management programs for various light sources according to the international regulations and domestic situation. First, a total of 20 participants took part in this field experiments in the CSMU University at Taichung of Taiwan and a total of 4,320 subjective questionnaires were collected. The questionnaire included the perception score of the maximum glare and the maximum flicker. Second, the luminance and illuminance monitoring, and flicker measurements of the LED combo lights in six locations in Taipei City and Hsinchu City, and the total number of measurement experiments was 216 times. Third, this study made summary and translation of 2 literatures about light pollution. This research revised a draft of luminance measuring method, a draft of vertical illuminance measuring method for dynamic light sources. In addition, a draft of flicker measuring method for LED billboards, a draft of flicker measuring method for LED combo lights were prosposed. In addition, there were divided into different stages to practice the prevention strategies of light pollution in accordance with urgency, feasibility and technical completeness based on domestic status and results in this study. Final, regulations were suggested for the prevention and management of light pollution, and completed a draft of “Guide for the light pollution management and control”.
