摘要

室內照明之參數中，水平照度、室溫、及光源色溫三者的組合，是任一場所可見的光環境變化。對使用者而言，其組合會產生有不同的舒適度、接受度與偏好。排除垂直面輝度、及色彩、風格之主觀影響，本研究於一足尺實驗室安裝3000K及6500K之T54×14W螢光燈具，以調光器及可升降天花板上的燈具高度提供三種照度。其內室溫以中央空調控制三種溫度，綜合搭配起來模擬18種均勻照明之光環境，供受測者實地體驗，填寫語意問卷反映心理感受。研究結果發現，雖然辦公室需要人們聚精會神工作，卻偏好3000K色溫之光線。此種色光滿足各種心理意象，似乎超越辦公室情境之設定限制；不喜好6500K色光，各語意皆呈現負面意象。室溫太低(20℃)及照度(200lux)太低都會對人們的視知覺及生理有負面影響。於此負面狀態下，光線的色溫改變生理上的負面感受並不顯著。相反地，人們多能忍受28℃室溫下對照明的評估。

Illuminance, room temperature, and correlated color temperature are essential parameters of every interior lit space. They vary a lot. However, their variations correspond to users’ visual perception, preferences and degrees of comfort. To quest into such preferences and perceptions by concentrating on these parameters, this study ruled out possible distractions from such concerns as walls' luminance, room colors, and design styles, and constructed a full scale test lab simulating office space. In which, 6 sets of 4 by 14 Watt T5 fluorescent tubes ware assembled on an aluminum ceiling frame. Operated concurrently with 3 levels of room temperature and 2 kinds of color light, this ceiling which was chained on the building structure to ascend and descend provides uniformly distributed down lighting in 3 different lighting levels to house 4 subjects who filled out semantic differential questionnaires. Through such a design, the test result showed that subjects preferred 3000K color light to 6500K's under all sorts of semantic terms. Although it is important that office attendants keep vital and concentrated, the subjects take to the yellowish lit ambiance beyond the concern of where and when one is located. In addition, lower room temperature (20℃) and lower lighting level (200 lux) cause negative responses to lit environment, while higher room temperature (28℃) was tolerable to subjects in most occasions.
