摘要

過去使用者往往習慣於視覺對象與周圍照度一致的照明環境，在維持空間照度連續性的前提下，卻造成不必要的能源浪費，然而混合照明的方式，能夠兼具視覺對象所需要之高照度與周圍照度均勻的特點，減少全面照明使用量，搭配局部照明使用，可有效達到降低照明耗能的目標。故本研究於視覺舒適與能源節約的角度，找尋符合需求的照明環境。
本研究擬探討混合照明環境與心理反應之關係，藉由模擬實驗的操作，選取30名受測者，在基本作業面照度的標準下，控制光輸出比例與色溫度變化兩項變因，進行主觀性的滿意程度評價，所得心理量結果，透過單因子變異數分析，針對所設定六種照度分配方式及四種光源色溫度變化，檢討心理滿意程度之差異，以相關分析，探討其相關性，並綜合節能效益評估，進而本研究所獲得之結論，可供混合照明設計之參考。
相關結論如下：
一、全面照明照度500 lx搭配局部照明照度0 lx與全面照明照度400 lx搭配局部照明照度100 lx之照度分配方式，其心理滿意程度較其他環境為高。
二、全面照明照度舒適性與混合照明環境品質滿意程度，兩者之間具有高度的正相關性。
三、混合照明環境設計上，同時滿足視覺舒適與節能的混合照明環境，建議使用全面照明照度400 lx搭配局部照明照度100 lx之組合方式。

In the past users are accustomed to the lighting environment where the illuminance of the visual target and its surroundings is identical. This attempt to maintain illuminance continuity in the space, however, results in unnecessary waste of energy. Meanwhile, mixed lighting can provide high illuminance for the visual target and evenly distributed illuminance for its environment and help reduce general lighting energy requirement. In association with the use of local lighting arrangement, we can effectively mitigate lighting energy consumption. This study therefore seeks to identify a lighting environment that meets the requirement from the perspective of visual comfort and energy conservation.
This study looks into the relations between the mixed lighting environment and psychological response through simulation experiment that involves 30 test participants. Under the basic operational lighting standard, two variables – light output proportion and color temperature – are placed under control for subjective satisfaction evaluation. The psychological measurement is put through single-factor ANOVA. In accordance with the six illuminance distribution methods and four lighting source color temperature changes, discrepancies in the degree of mental satisfaction are examined. The correlations are examined via various analytical tools in conjunction with assessment of the overall energy conservation performance. The conclusions of this study can serve as reference for mixed lighting design.
The conclusions are listed below:
1.The mental satisfaction of two illuminance arrangements – a general illuminance of 500 lx in association with a local illuminance of 0 lx; a general illuminance of 400 lx in association with a local illuminance of 100 lx – is higher than that of other environments.
2.The general illuminance comfortableness and the mixed lighting environment satisfaction are highly positively correlated.
3.The mixed lighting environment can satisfy both the requirement of visual comfort and energy conservation. It is recommended that the lighting arrangement that involves a general illuminance of 400 lx and a local illuminance of 100 lx be used.
