摘要
白光LED燈具當作工作、閱讀及環境照明用途，是近來世界各國都積極發展之產品，也因此出現大量類似產品，因為它是節能的光源。但是限於目前的製作技術，其光色及光譜組成與傳統鎢絲燈、鹵素燈、或螢光燈有很大差異，造成其在演色、膚色、光分佈等特別要求的照明使用上仍有不足。也因此造成人眼在接受度上的極大限制，雖名為照明用途，目前不但仍未被廣泛使用，適用場合也不明確。為掌握人們的接受度，本計畫蒐集市面上被稱為足以做照明應用之白光LED燈具樣本，探究其照明參數之人眼視知覺偏好。首先於模擬實驗室裝置14組物體展示箱，供受測者於其中體驗照明效果並填寫態度量表。所得資料經平均數、T檢定、及多元尺度法之屬性評量程式軟體統計，並繪製「偏好認知架構圖」，解釋偏好範圍。研究結果發現，人們可接受6500K、二波長白光LED為室內照明光源；較不喜歡5000K以下色溫之LED白光照射下的膚色，但可接受6500K照射下之物體表面色彩；人們對於白光LED室內照明之偏好認知意象，可以二個向度偏好認知座標圖詮釋；男女性別族群對於白光LED照明之喜好無顯著差異；及目前白光LED之演色係數，未能做為判斷色光或膚色偏好之根據。

Abstract

It is not until the last decade that white light LEDs are considered possible light source for task lighting, reading, and ambient lighting. Such products are manufactured mainly due to LEDs’ energy saving feature. Unfortunately they are incomparable to tungsten, halogen, and fluorescent laps in the sense of color rendering index, skin tone, and light distribution pattern since the beams emitted from LEDs are different spectrally. People are reluctant to accept this type of light for such a visual related shortcoming. Although made for lighting purposes, they are not widely used nor are they appropriately adopted. Thus, this research collected sample lamps to learn how people view such a light source and what parameters pertain to their preferences. To do so, respondents are invited to observe and fill out questionnaires on display windows where 14 lamp samples are mounted. The collected data are statistically processed to obtain mean value and T tests scores. Further, Multidimensional Preference Scaling program is employed to generate Perceptual Mapping of respondents’ visual preferences. It is concluded first, that people would accept 6500K white light LEDs as an interior light source; they dislike skin tone under 5000K white light LEDs, yet they take to color appearance of objects under 6500K light beams. Second, the two-dimensional perceptual mapping is appropriate to interpret respondents’ visual preference for specific white light LEDs. Third, there is no gender difference found in such a preference pattern. Finally, it can be certain that color rendering indices of LED light sources are irrelevant to respondents’ preferences.
