The introduction of solid-state lighting, coinciding with the recent research into the psychological and physiological effects of light, has brought a wider range of possibilities to the lighting practice with the promise of new design paradigms. Given this background, this study aims to investigate how dynamic lighting could be employed to support students' learning. Dynamic lighting is lighting that changes―that is not always static. The study will, in particular, focus on the potential of dynamic lighting to support students' academic achievement and health. First, a series of three complementary experiments was conducted to identify how lighting conditions could be tailored to support different learning activities and thereby promote students' academic achievement. The result shows that the cooler, 6500 K lighting led to stimulation of a higher arousal level and the greatest enhancement of academic performance, while the warmer, 3500 K lighting was the most relaxing. While academic achievements associated with sustained attention can be improved under cool light exposure, some controversy remains with respect to students' health risks. Hence, a laboratory experiment was conducted to design intervention between students' academic achievement and health. The resulting evidence suggests that an excessive exposure to 3500 K lighting during the morning and 6500 K lighting during the evening should be prohibited in order to maintain students' health. Lastly, a list of considerations to be taken into account when planning the lighting of learning environments was presented. Although further research is necessary, the study is expected to provide the basis for major changes in future lighting strategies and thereby shed light on better learning environments.
본 연구에서는 조명 환경이 학생들에게 미치는 영향을 탐색하여 학습 환경을 위한 동적 조명을 제안하고자 한다. 본 연구는 두 가지 과정으로 이루어져 있으며, 단계별 세부 내용은 다음과 같다. 첫째, 사용자의 생리, 행동, 자가 반응을 바탕으로 조명 환경이 학습성취도에 미치는 효과를 규명하였다. 그 결과 휴식, 표준, 집중 활동에 각각 3500K, 5000K, 6500K 조명이 적합함을 확인하였다. 둘째, 제안된 조명 환경의 장시간 사용에 따른 생리 및 자가 반응을 탐색하였다. 평가 결과 아침, 저녁 시간대에 각각 3500K, 6500K 조명을 장시간 사용하였을 시 학생들의 건강에 해로운 영향을 줄 수 있음을 관찰하였다. 연구 결과에 기초하여 학습 환경의 조명을 설계하는 과정에서 활용될 수 있도록 고려 사항을 제안하였다. 본 연구를 통해 제시한 동적 조명이 학생들의 학습을 지원하는 데 도움이 되기를 기대한다.
