摘要

本研究由照明節能的新觀點，以能反映照明耗能量的照度水準爲指標，探討室內空間的照度分佈型式與視覺明亮感、眩光感與舒適感的對應關係。結果顯示，照度分佈型式對明亮感與舒適感皆有顯著的影響，但對眩光感則無影響。在所探討的20組照度分佈型式中，明亮感與舒適感較高者皆爲空間照度分佈較均勻與光源屬對稱配置者。照明的均齊度與明亮感、舒適感之間皆存在著顯著的正相關。此外，明亮感與舒適感之間也存在著顯著的正相關，愈明亮的照明環境其舒適感也愈高。對此，若能應用本研究的結論，藉由控制照度分佈提升明亮感與舒適感，間接減少室內空間的整體照度水準，不但可滿足空間使用者的主觀心理需求，對照明系統的節能也將有相當的貢獻。

In this research, illuminance level, which meausres the quantity of energy consumption of lighting, was used as an index to study the relationship between interior illuminance distribution and energy saving. Effects of illuminance distribution on such subjective evaluations as brightness, glaring and comfort were studied. The results showed that brightness and comfort vary significantly with the types of illuminance distribution. Among all 20 types, the ones with well-balanced illuminance distribution led to higher brightness and better comfort. And, a significant positive correlation existed between brightness and comfort. The obtained results suggest that the effect of controlling interior illuminance distribution can be used to improve brightness and comfort without consuming extra energy, or to reduce interior illuminance level under a condition of equal brightness and comfort.
