  • Recently, a drain of energy resources is issued seriously. The daylight responsive dimming systems can reduce electric energy uses. But, we cannot predict amounts of energy-saving and accuracy of system performance. Therefore, the purpose of this study is a development of software for the system performance of daylight responsive dimming systems. The principle of this software based on luminous flux transfer method and finite elements method. The control algorithm of this software and daylight responsive dimming systems use the same algorithm. In addition the advantages of this software are use to same algorithm of daylight responsive dimming systems, electric power-luminous flux data and rates of frequency of sky conditions. Therefore, this software can predict more correct calculation about illuminance and amounts of energy-saving of daylight responsive dimming systems.

  • 에너지 자원의 고갈과 환경오염으로 인하여 건축조명 분야에서는 주광을 이용하여 에너지를 절약하는 연구가 활발히 진행되고 있다. 광센서 조장제어시스템은 실내로 입사되는 주광에 따라 인공조명을 자동으로 제어하는 에너지 절약형 시스템으로 쉐이딩 시스템에 의해 주광유입이 차단되어 그 적용성이 미비하다. 자동롤러쉐이딩 시스템은 태양의 변화에 따라 롤러쉐이드의 높이를 자동으로 제어하는 시스템으로 광센서 조광제어시스템과 통합되어 사용될 때, 불쾌한 직사일광은 차단하고 실내로 유용한 주광을 유입함으로써 에너지 절감과 쾌적한 시환경을 제공할 수 있다. 본 연구는 광센서 조광제어시스템과 자동롤러쉐이딩 시스템의 통합을 위하여, 각 시스템의 제어 소프트웨어를 개발하였고 이를 통합하였다.

  • Recently, energy depleting problem have risen seriously. Many studies of daylight responsive dimming system for saving of lighting energy in office buildings have been done actively. Most of studies are focused on the accuracy. However if the variation of dimming levels is changed too often, occupants would feel uncomfortable. First, illuminance changes which occupants couldn't detect are studied through analyzing foreign studies. Second, workplan illuminance from daylight in each sky condition is measured. Because the dimming level In daylight responsive dimming system is dependent on the workplan illuminance from daylight. In conclusion, the most appropriate polling periods to daylight responsive dimming system for occupant's visual comfort was determined.

  • The daylight responsive dimming systems, which use daylight and automatically controls the brightness of electric lighting, according to the amount of daylight coming into the indoor, as well as always maintains target illuminance, is an energy saving type system. The control slope that decide the dimming percent for dimming ballast to run this system efficiently should be decided exactly. This research ran performance assessment applying daylight responsive dimming systems to actual space, and supplemented control slope in the sky condition for the elevation of system. Also we revaluated a system by modified control slope and compiled valid propriety and alternative for the elevation system.

  • 광센서 조광제어시스템은 유용한 주광의 실내유입을 통하여 인공조명의 에너지를 절감하는 시스템이나, 쉐이팅시스템에 의한 주광유입의 차단으로 인하여 그 적용성은 미비하다. 따라서 광센서 조광제어시스템의 적용성 및 에너지 절감량 향상을 위해서는 자동롤러쉐이딩 시스템과의 통합은 필수적이다. 본 연구는 두 시스템을 통합한 주광이용 조광제어시스템의 적용성 향상을 위하여 시스템 적용 시 에너지 절감량을 예측할 수 있는 프로세스를 개발하고 이를 사례에 적용하였다. 개발된 프로세스는 주광이용 조광제어시스템의 초기투자비용 환수 및 시스템 적용을 위한 타당성 분석의 자료로 이용될 것이다.

  • 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.

  • This study based on the experimental data on the daylight responsive dimming systems performance. The purpose of this study increases the energy-saving effects by reducing excessive intensity of radiation of artificial lighting through analyzing incident daylight. The photosensor sends amounts of detected luminous flux to digital control unit(DCU) as a signal and then, it can decide dimming ratios, by received a proper dimming signal from DCU. Generally it is effective to control artificial lighting with the different control ratio of each row by setting a photosensor as same numbers and rows as artificial lighting. However, it is ineffective to do in initial costs of systems aspect in offices. By analyzing the data of this performance and finding regular ration between photosensors. we will execute different dimming ratios to each row of artificial lighting by a single photosensor.
