  • The design of road lighting is aiming illuminance and luminance requirements for road lighting. In the process, various factors associated with luminaires such as luminous efficacy, light distribution, mounting height, spacing and maintenance factor are considered. However, there has been no restriction on lighting power density. In this study, lighting power density has been comparatively analyzed through a study of related data and a result of measurements on domestic roads. And, it has been analyzed by simulation results for road in which lighting conditions are variable. In terms of the limitation on power density for road lighting, road lighting can be designed using high efficacy lighting systems for energy saving.

  • In this paper, we proposed a smart lighting management system controls the lighting efficiently to reduce energy consumption while satisfying user's lighting requirements. The proposed system considers the available daylight intensity and indoor light source to satisfy the lighting requirements of each user according to the work environment. In addition, for user convenience, we have developed different user interfaces for lighting control including local interface, and remote interface through internet or Bluetooth for personal computer as well as smart phones. The proposed system satisfies the lighting requirements of each user according to the corresponding work environment. The proposed smart lighting management system utilizes the lighting energy efficiently, and can be considered a significant contribution towards future green buildings.

  • This study describes the difference of lighting directing techniques of between asian and westerner in the residential space, and presents the LED lighting environment according to the residents' behaviors. This study was conducted with Koreans, European and North Americans, and the space range was limited to the living room where the various activities occur. The data of the desired LED lighting environment is drawn through lighting technique, illumination color temperature and illuminance variation of LED in living room, and the detailed study results are as follows ; First, the lighting in living space should be made with considering the various behaviors because the expected level according to consideration or not of behavior makes much difference. Second, the comfortably feeling LED lighting environments that are lighting technique, illumination color temperature and illuminance variation, are different between Koreans and North Americans, but Koreans and European feel comfortable under the similar LED lighting environments. Third, the data for the comfortable LED lighting environments is established according to the various residents' behaviors, which are watching TV, reading, studying, relaxing, chatting, entertaining guests. And then, the established LED lighting environments are analyzed with characteristic of behavior and classified according to lighting technique, illumination color temperature and illuminance variation for understanding their characteristic Few studies have been conducted to find out difference of the comfortably feeling LED lighting environment between asians and westerners. Therefore, in this study, it has a great significance to present the difference of the LED lighting environments that asians and westerners feel comfortable in living space, and to draw the characteristic of the expected lighting environment according to residents' behaviors.

  • Nowadays, the lighting of urban nightscape has become important for improvement in city. Lighting the outdoor is different that lighting an interior. Outdoor lighting designs should be designed to minimize glare, light trespass, light clutter and energy conservation to avoid light pollution. Mokpo city launched into a large scale project of the city beautification using outdoor lighting. However, outcomes of outdoor lighting project have faced strong opposition from environmental groups. This study aims to analyze the light pollution of outdoor lighting in Mokpo-si for creating a health night environment. The Radiant Imaging Prometric-1400 was used to measure the luminance of Yudal Mountain, Goha Island and Luminarie Street. The result showed that the all the outdoor lighting produce light pollution and some places like mountain and island did not need a lot of lighting all the time.
