주거공간별 조명 적용 특성 및 조도·색온도 특성 조사 연구

In this study, I reexamine the earlier studies performed since 2000 on lighting applied in residential spaces and verify the trends in the changing environment for lighting in residential space by making a comparative analysis linking to the results of the current study. Also, I have analyzed the properties of illuminance and color temperature for different spaces through measuring luminous environment and come up with related problems, with following results. 1) While in the earlier studies, incandescent light bulbs are frequently used for dining table and porch sensors, in the current study, incandescent light bulbs are no longer used and fluorescent light is adopted for dining table while LED light is adopted for door sensors. The study shows that while fluorescent light is still used as main light for living room, bedroom, kitchen, and bathroom, LED light is adopted for short-time use or accessory lighting such as door sensors, guiding light in bathroom and hallway, and decorative light in the hallway. In comparison with earlier studies, the current study shows no great difference in lighting method and light fixture type. As far as luminous environment control is concerned, the study shows that while two-stage light on and off is possible for living room and bedroom, brightness control is impossible for bathroom, kitchen, dining area, porch, and hallway. Furthermore, color temperature control is not possible in all of the cases. 2) The measurement of average illuminance for different areas, the illuminance as required by KS can be secured for living room and anbang, whereas for the study room, it is brighter than required for play activities and darker than required for study or reading. Also, the brightness for bathroom, kitchen, porch, and hallway is considerably higher than is required in KS for general lighting. The illuminance for the kitchen is roughly in the scope of illuminance as required by KS, but as the scope of illuminance for the area with the second largest portion appears higher than required by KS, it registers excessive brightness. 3) The measurement of color temperature for different spaces shows that the color temperature applied in housing is planned at 2800-4000 K and 5500-6000 K. Also, on the whole, different spaces apply the same scope of color temperature for a single type.
