中文摘要	目前民眾受到光污染的影響情形日漸嚴重，陳情案件增加，依據我國國情特性，調查及研析民眾對光污染類型之人體舒適性感受程度，以提出光污染相關防制對策建議。本計畫已完成法規蒐集彙整、科學研究文獻10篇之摘譯分析；配合民眾陳情情形，選定閃爍、眩光及色飽和等3個光污染因子，完成LED看板64點次閃爍與眩光量測，以及色飽和眩光以及閃爍之人因實驗；完成專家諮詢會議1場；並依據研究結果提出光污染防制相關建議。本計畫相關研究結果說明如下：一、色飽和眩光研究結果：本研究採用9張彩色影像呈現於LED看板，進行色飽和眩光人因實驗，研究得知影像品質(色飽和)對於受測者的眩光舒適度評價有相當的影響；有關色飽和眩光舒適度的平均笛波爾(de Bore)分數，男性與女性分別為4.66分及3.93分，而40歲以上的中老年族群及40歲以下的青壯年族群，則分別為4.54分及4.05分。於本計畫實驗條件下，眩光舒適度的平均笛波爾分數，對於不同之年齡族群、性別族群，皆為接近恰可接受(5分)與妨礙(3分)之間的水準。本項研究受測者共20人(3240人次)參與。二、閃爍研究結果：不同的年齡分組之人因實驗結果，並未獲得統計上的顯著影響性，但仍可討論年齡的影響趨勢。40歲以上和40歲以下的族群，眩光舒適度的平均笛波爾分數分別為3.41分(標準差1.47分)、4.67分(標準差0.64分)。前述40歲以上的閃爍實驗受試者，其平均笛波爾分數較低，此與色飽和眩光實驗結果恰好相反，推測其因素可能是閃爍實驗為單純的白方塊測試圖案，而色飽和眩光實驗採用靜態彩色影像，所以造成此差異。另閃爍頻率於32 Hz的平均笛波爾分數為4分。本項研究受測者共25人(1275人次)參與。三、在光污染防制策略上，依據色飽和眩光人因實驗使用的LED看板平均亮度推算眩光評價函數，結合眩光舒適度平均笛波爾分數的結果，可以得到眩光評價亮度建議表，於平均笛波爾分數5分及4分，實驗結果對應之LED看板的平均亮度最大值分別為618 cd/m2 、1590 cd/m2，這些亮度值，可做為未來訂定相關管制策略之參考。因此，在不減低影像品質的前提下，降低色飽和並降低亮度，則可減少眩光的發生機率，同時從節能的角度，亦可降低能耗，也能降低用電成本，一舉數得。四、依本計畫之研究結果，影像品質、環境背景亮度、亮度、閃爍頻率可能有交互作用，建議未來可針對此這些因子的交互作用進行更深入的研究與探討。

中文摘要

目前民眾受到光污染的影響情形日漸嚴重，陳情案件增加，依據我國國情特性，調查及研析民眾對光污染類型之人體舒適性感受程度，以提出光污染相關防制對策建議。本計畫已完成法規蒐集彙整、科學研究文獻10篇之摘譯分析；配合民眾陳情情形，選定閃爍、眩光及色飽和等3個光污染因子，完成LED看板64點次閃爍與眩光量測，以及色飽和眩光以及閃爍之人因實驗；完成專家諮詢會議1場；並依據研究結果提出光污染防制相關建議。本計畫相關研究結果說明如下：一、色飽和眩光研究結果：本研究採用9張彩色影像呈現於LED看板，進行色飽和眩光人因實驗，研究得知影像品質(色飽和)對於受測者的眩光舒適度評價有相當的影響；有關色飽和眩光舒適度的平均笛波爾(de Bore)分數，男性與女性分別為4.66分及3.93分，而40歲以上的中老年族群及40歲以下的青壯年族群，則分別為4.54分及4.05分。於本計畫實驗條件下，眩光舒適度的平均笛波爾分數，對於不同之年齡族群、性別族群，皆為接近恰可接受(5分)與妨礙(3分)之間的水準。本項研究受測者共20人(3240人次)參與。二、閃爍研究結果：不同的年齡分組之人因實驗結果，並未獲得統計上的顯著影響性，但仍可討論年齡的影響趨勢。40歲以上和40歲以下的族群，眩光舒適度的平均笛波爾分數分別為3.41分(標準差1.47分)、4.67分(標準差0.64分)。前述40歲以上的閃爍實驗受試者，其平均笛波爾分數較低，此與色飽和眩光實驗結果恰好相反，推測其因素可能是閃爍實驗為單純的白方塊測試圖案，而色飽和眩光實驗採用靜態彩色影像，所以造成此差異。另閃爍頻率於32 Hz的平均笛波爾分數為4分。本項研究受測者共25人(1275人次)參與。三、在光污染防制策略上，依據色飽和眩光人因實驗使用的LED看板平均亮度推算眩光評價函數，結合眩光舒適度平均笛波爾分數的結果，可以得到眩光評價亮度建議表，於平均笛波爾分數5分及4分，實驗結果對應之LED看板的平均亮度最大值分別為618 cd/m2 、1590 cd/m2，這些亮度值，可做為未來訂定相關管制策略之參考。因此，在不減低影像品質的前提下，降低色飽和並降低亮度，則可減少眩光的發生機率，同時從節能的角度，亦可降低能耗，也能降低用電成本，一舉數得。四、依本計畫之研究結果，影像品質、環境背景亮度、亮度、閃爍頻率可能有交互作用，建議未來可針對此這些因子的交互作用進行更深入的研究與探討。

摘要	People are subject to the effects of light pollution is become increasingly serious, petition cases also increased, based on the characteristics of conditions of our country, we investigation and analysis of the degree of light pollution types of human comfort sensation, and proposed a proposal of light pollution control strategy. In this project, we study the light pollution issue, which include the study on 10 literatures and regulations, analyze the petitions of citizens and practice the ergonomic experiments of LED screen on the parameters, such as color saturation, glare and flicker, etc. We also complete an expert advisory meeting and complete 64 physical test results of glare and flicker impact of LED screen. Based on the above study, we got a proposal of light pollution control strategy. In study the color saturation and glare evaluation experiments of LED screen using 9 color images, we find out the image quality of LED screen under test will affect the de Bore glare evaluation score. The averaged de Bore scores of female and male are 3.93 and 4.66, respectively. The averaged de Bore scores of elder people (above 40 years old) and younger people (under 40 years old) are 4.54 and 4.05, respectively. These four averaged scores are between ~4 and 5, which mean they are between just acceptable (de Bore score 5) and disturbing (de Bore score 3). There are 20 objects involve in this study, and related collected data are 3240. In the flicker evaluation experiments, we show simple white block on LED screen. We find out, the averaged de Bore score of elder people (3.41±1.47) is less than younger people (4.67±0.64). This result is conflict to result from color saturation and glare experiments, which might due to the basic characteristics of test patterns of these two experiments, are different significantly, which might be due to static color images used in color saturation and glare experiment, while flickering white block test pattern used in this experiment. The corresponding averaged de Bore score of 32 Hz is 4. There are 25 objects involve in this study, and related collected data are 1275. For the control strategy of light pollution, we got a luminance suggestion table of respective glare evaluation score from the color saturation and glare evaluation experiments. Base on this table, we suggest the maximum average luminance can be 618 cd/m2(de Bore score 5) or 1590 cd/m2(de Bore score 4). These luminance values can be used as a reference of the management strategy set in the future. Hence, we suggest to reduce the color saturation and luminance without scarify image quality of LED screen. This suggestion will reduce the glare and energy consumption and electricity cost. This suggestion will also benefit to the citizens and the environments. According to above results, we suggest to study the interaction between the parameters, such as background luminance, image quality, luminance and flashing frequency of LED screen, in the near future.

摘要

People are subject to the effects of light pollution is become increasingly serious, petition cases also increased, based on the characteristics of conditions of our country, we investigation and analysis of the degree of light pollution types of human comfort sensation, and proposed a proposal of light pollution control strategy. In this project, we study the light pollution issue, which include the study on 10 literatures and regulations, analyze the petitions of citizens and practice the ergonomic experiments of LED screen on the parameters, such as color saturation, glare and flicker, etc. We also complete an expert advisory meeting and complete 64 physical test results of glare and flicker impact of LED screen. Based on the above study, we got a proposal of light pollution control strategy. In study the color saturation and glare evaluation experiments of LED screen using 9 color images, we find out the image quality of LED screen under test will affect the de Bore glare evaluation score. The averaged de Bore scores of female and male are 3.93 and 4.66, respectively. The averaged de Bore scores of elder people (above 40 years old) and younger people (under 40 years old) are 4.54 and 4.05, respectively.

There are 20 objects involve in this study, and related collected data are 3240. In the flicker evaluation experiments, we show simple white block on LED screen. We find out, the averaged de Bore score of elder people (3.41±1.47) is less than younger people (4.67±0.64). This result is conflict to result from color saturation and glare experiments, which might due to the basic characteristics of test patterns of these two experiments, are different significantly, which might be due to static color images used in color saturation and glare experiment, while flickering white block test pattern used in this experiment. The corresponding averaged de Bore score of 32 Hz is 4. There are 25 objects involve in this study, and related collected data are 1275.
