摘要 「照明」,是創造健康舒適的生活環境不可或缺的一環,隨著人們對生活環境品質的要求,室內照明也倍受重視。目前無論商業空間、公共場所、居家空間,在照明的應用上,不但顧慮照明效率也相當重視視覺感受,以致於應用直接照明與間接照明的手法已非常普遍。為分析直接照明與間接照明人們的感知偏好,本研究針對人們對於直接與間接照明於室內空間中分佈的主觀反應加以探討。其方法為於一1.98米×4.28米之足尺實驗室中,配置嵌入式T-bar螢光燈照明設備,維持600 lux桌面照度,變換直接與間接照明的比例,供受測者親身體驗光環境之變化並比較個人偏好。偏好之反應以語意分析法問卷蒐集,並以多元尺度評量法之屬性評量統計軟體(MDPREF)綜合統計偏好所在,並以之繪製偏好知覺圖。研究結果發現,在桌面照度保持不變時,間接照明是最獲得受測者所偏好。 關鍵詞:直接照明、間接照明、語意分析法、多元尺度評量。
Abstract Lighting is one of essential element for achieving the heath and comfort building environment. Today, in the variable application of lighting spaces i.e. including commercial, public or residential space, the efficiency of lighting should be take into account and the sense of visual environment as well. Consequently, the methods of the direct and indirect lighting are generally applied in the field of interior design. In order to realize the different perception of human being under the condition of direct lighting and indirect lighting circumstance, this literature study the instinctive reaction of the people who be tested in the two different indoor lighting environment above. The method we employed in this literature is the T-bar fluorescent light to be mounted in an experimental space with dimension of 1.98 x 4.28 meters and keep the illumination of the desk surface in 600 lux. Then change the ration of these two lighting sources for tester to percept and compare the change of lighting environment. The questionnaire data were collected within semantic analysis that based on the personal preference, and then interpret the data through the software of MDPPEF to produce the chart of these variable preferences. The study shows that the most testers prefer indirect lighting environment more than direct lighting in the physical condition of same illuminance of the desk surface.
