| Summary: | 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.
