대학교 강의실 빛 환경 실태조사 및 만족도 조사에 관한 연구

Abstract

This study examined university classrooms in Korea by measuring illuminance levels, investigating the use of lighting fixtures and blinds, and analyzing students’ subjective perceptions. The results showed that natural lighting was insufficient, while excessive illuminance was caused by artificial lighting. In 64% of classrooms, blinds blocked natural light, and 86% operated with more than half of the general lighting, creating conditions unsuitable for both textbook- and projection-based instruction. Survey results indicated that textbook readability required about 340 lx, with a stable visual environment achieved at 600 lx, consistent with the KS A 3011 standard. However, students perceived levels above 891 lx as “bright.” These findings demonstrate that classroom lighting plans focusing only on horizontal illuminance do not adequately address the needs of digitalized learning environments. Future classroom lighting design should therefore consider not only illuminance levels but also light source arrangement, blind operation, and screen reflectance to improve visual comfort.
