  • This study has attempted to investigate how subjects perceive changes of brightness and their visual comfort according to daylight responsive LED(Light Emitting Diode) dimming systems in the office with venetian blind. Two studies was conducted. First study is that how subjects perceive changes of brightness and their visual comfort depending on angle control method of the venetian blind while the workplane illuminance level is being maintained through daylight responsive LED dimming system. Second study is that how subjects perceive changes of brightness and their visual comfort depending on the amount of daylight penetrated into the building while the illuminance level is being maintained through daylight responsive LED dimming system. The results of this study could be proposed as basic data in the control of the venetian blind and LED lighting in consideration of their perception on changes of brightness and visual comfort.

  • Today, energy problem has become an important issue, and a development of renewable energy is urgent. In architectural fields, a research of the energy efficient lighting system using renewable energy is in progress. The energy efficient lighting system could be realized by integrating a daylight responsive LED lighting control system and a blind PV system. This system is able to save and generate electric energy. Efficiency of this system depends on control methods of blind PV. As a preliminary research, this research analyzed power generation and inflow of available daylight according to control method of blind PV.
