  • This study proposes to increase the energy-saving effects by reducing excessive intensity of radiation of artificial lighting through analyzing daylight incident. A photosensor sends amounts of detected luminous flux to digital control unit(DCU) as a signal and then, it can decide dimming ratios, received a proper dimming signal from DCU. Generally it is effective to control artificial lighting with the different control ratio of each zone by setting a photosensor as same number and rows as artificial lighting. However, it is ineffective to do in initial costs of systems aspect in offices. As a result of grasping the distribution of daylight previously and analyzing daylight and dimming data, we can dim different dimming ratios to each zone of artificial lighting by a single photosensor.

  • 현재의 오피스는 공간이 좁고, 바닥위의 배선이 장애물이며, 형광전구가 노출된 조명으로 실내 작업환경에 대한 고려가 매우 미약한 점에 의심할 여지가 없다고 생각된다. 특히 OA기기의 도입에 따른 집무 공간의 감소, 프린터 소음, 기기의 발생열, 배선, VDT(Visual Display Terminal:화면이 있는 OA기기) 작업과 관련된 환경 관리, 작업관리, 건강관리의 필요성등의 문제가 발생하고 있다. 그러므로 쾌적한 분위기를 구성요소로 조명은 실의 LAY OUT, 표면처리, 배색등 인테리어 디자인과 함께 그 효과를 최대한으로 연출하도록 되리라 생각된다. 따라서, 자연채광 이용을 통하여 절감될 수 있는 인공조명(형광등)의 제어방법으로서 본 논문에서는 점멸방식(ON,OFF)을 시도하였으며 점멸에 따른 급격한 조도저하를 보다 심리적인 차원을 고려한 실내조명 조광장치(천정형태와 외부에 댄 반사판)로 인한 실내조도 분포의 영향에 대하여 파악하고자 하였다.

  • Recently, the utilization of subway stations for varied working spaces is beginning to receive more attention. However, due to feeling of closeness and rejection to the underground, a daylighting is useful to alleviate the complaints of subway environments. This paper aims to investigate and evaluate the luminous environments of subway stations with and without daylighting in Seoul. At the first stages, the field experiments are performed to estimate the illuminance levels of chosen three subway stations. And then, the interview and questionnaire surveys are conducted to evaluate the luminous atmospheres of them. As results, the daylighting effects to subway visual environments are analyzed. Also, the basic data for a daylighting design are suggested.

  • As the economic growth achieved and the straight road was increased. so, the tunnel built more than before. In these days, lighting of tunnel entrance is important for safety and comfortable driving. Most of the tunnel lighting depend on artificial lighting and they use a lot of energy. In this paper, as a research for illumination improvement and saving energy at tunnel, reflecting mirror system is suggested. The performance of the system was evaluated with respect to various aspects. By applying a reflective mirror system, tunnel lighting and environment can be improved. This study is a preliminary study for developing a system to save energy of tunnel artificial lighting.

  • Artificial intelligence (AI) technology has been evolving to recognize and learn the languages, voice tones, and facial expressions of users so that they can respond to users' emotions in various contexts. Many AI-based services of particular importance in communications with users provide emotional interaction. However, research on nonverbal interaction as a means of expressing emotion in the AI system is still insufficient. We studied the effect of lighting on users' emotional interaction with an AI device, focusing on color and flickering motion. The AI device used in this study expresses emotions with six colors of light (red, yellow, green, blue, purple, and white) and with a three-level flickering effect (high, middle, and low velocity). We studied the responses of 50 men and women in their 20s and 30s to the emotions expressed by the light colors and flickering effects of the AI device. We found that each light color represented an emotion that was largely similar to the user's emotional image shown in a previous color-sensibility study. The rate of flickering of the lights produced changes in emotional arousal and balance. The change in arousal patterns produced similar intensities of all colors. On the other hand, changes in balance patterns were somewhat related to the emotional image in the previous color-sensibility study, but the colors were different. As AI systems and devices are becoming more diverse, our findings are expected to contribute to designing the users emotional with AI devices through lighting.

  • An artificial light source has a character that a light emits from a point to all directions with many radial and straight ray shapes. It is very difficult and complex to render those emitting lights. Also, users have difficulty in expressing exactly 3D objects because of colors varying with changing of a light and having many parameters. In this paper, to solve those problems we design an artificial light source using X3D to create a model that represents easily many radial and straight ray shapes and propose the online system that each factors of colors to be reflected by a light is separated and then users can control them to detect object's colors by a mouse. Various light sources with reality can be easily created using proposed system.

  • This paper presents field measurements on daylighting and electric lighting with dimming controlled systems for a small office in Seoul, Korea. And the main purpose of this study is to provide the evaluation data of lighting energy performance when a dimming system is installed. For the performance evaluation, the mock-up room(3.6x7.2x2.6[m]) was used for the actual test. The results of this study were as follows; 1) The correlation between daylight illuminance at a workplane(Ed) and the photosensor signal(Sd) was an important factor affecting the performance of daylight responsive dimming system, 2) The mock-up office space gained a sufficient workplace illuminance of 579[lux] with the dimming control system 3) About 53[%J of monthly lighting energy could be saved using the dimming control system.
