Abstract
Existing LED-based classroom lighting systems too were designed to adjust color temperature and intensity of illumination, etc. for visual pleasantness and concentration of the teacher and students, but most of them are controlled manually, which causes inconvenience to users. To address this problem, it is necessary to develop an intelligent lighting control system that recognizes the locations and behaviors of the teacher and students automatically by means of sensors; grasps the current class context; and creates appropriate lighting environments accordingly. Thus, this study suggests a classroom lighting system to grasp the current class context to create appropriate lighting environments in recognition of the locations and behaviors of the teacher and students by means of sensors. Based on existing research findings, a standard index for lighting illumination effective for concentration depending on the subjects is designed. LED lighting whose color temperature, intensity of illumination, and on/off switch are adjustable in addition to hybrid sensors for context-awareness is produced. In addition, such elements as learning schedule, current class context, and lighting illumination are monitored real time on a user interface screen, or the lighting combination that the teacher desires is recreated with the learning schedule modifiable accordingly.
