垂直壁面佈光形式之心理感受研究--以檐板間接照明方式為例

Psychological Effects of Light Distribution Patterns on a Vertical Wall -- Taking the Cornice Lighting as an Example

由於國人對生活品質的要求漸漸提升，對燈光要求不單單侷限於照明而已，對於照明設計也逐漸多樣化；除了常用的直接照明外也開始關注間接照明及各式角度的光照射，讓燈光除了具備水平作業面的照明質量外，也注重到垂直觀視面的視覺觀感。 本研究以檐板形式之間接照明，探討其在室內垂直壁面的輝度分布與其型態造成的視覺心理感受，在1：1足尺實驗室中透過控制光源之色溫度及檐板離壁間距等二項變因，建構15組不同佈光型態之壁面環境，讓30位受測者其年齡分布在18至22歲之大學生以SD語意分析法問卷進行主觀的評價，本研究所獲致的結論可知，第一，壁面佈光型態對於所列之評價項目皆有顯著性的影響，第二，色溫度不同與光源離壁間距增減所形成的明亮分布，可就氛圍性、光配性、戲劇性等三方面影響觀者視覺心理感受，第三，本研究提出輝度分布辨識率Rmm％可作為應用於實際場所評價其垂直作業面明亮感之判斷。

 

In addition to the commonly used direct lighting, attention is also paid to indirect lighting and various angles of light irradiation. Therefore, along with the lighting quality for horizontal work plane, it also pays attention to the visual perception of the vertical wall surface. This study took cornice lighting system as an experimental subject to analyze the visual psychological feelings for the brightness distribution and pattern of vertical wall. In a 1:1 full-scale space laboratory, the color temperature and the off-wall distance were controlled, and 15 variations of wall conditions of different lighting patterns were set up. This study reaches three conclusions. First, the brightness distribution formed by the difference in the color temperature and the off-wall distance between light source and the wall has a significant influence on the listed evaluation items. Second, viewers’ visual psychological feelings were affected by three aspects: atmosphere, light distribution and dramatic contrasts. Third, the brightness distribution recognition rate Rmm% can be a determinant of brightness distribution design on the wall.
