碩士 === 國立臺灣科技大學 === 工程技術研究所 === 86 === The main focus of this study is to understand the classroom direct glare effect of exceeded luminance coming from the suspended luminaries in the situation of student looking to the blackboard and no daylight inference condition. The results of this experiment show that among the three types of classroom luminaries, the cut-off type with better shielding angle and layout setting paralleled to blackboard has lower glare effect. It also shows that either non-cut-off type or semi-cut-off type luminaries with layout perpendicular to the blackboard have lower glare effect. Students whose seat position near to the classroom central line and at front area expresses higher percentage of eye irritation causeed by the luminaries. Finally a regression model of glare level rating is established for the non-cut-off type luminaries of classrooms from the total thirty observer samples of the experiment. The main contents of this study are as followings : 1. To collect information and establish research frame , which include field lighting investigation , influential factor analysis. 2. To simulate experiment and conduct surveys , which include full scale testing, subjective psychological quantity of testes , and luminance of various viewed objects. 3. To analyze statistically and establish evaluation method, which include variance analysis among various layouts of lighting fixtures, comparison between regression model of direct glare evaluation and Luminance Curve of Europe. 4. To make conclusion and suggestion.
