조명시뮬레이션 소프트웨어는 크게 조명기구의 광학설계를 위한 소프트웨어와 조명계획안의 예측 및 평가를 위한 소프트웨어로 구분할 수 있으며, 그 사용이 점차 증가하고 있다. 조명기구의 광학설계를 위한 시뮬레이션 소프트웨어로는 Photopia 2.0이 대표적이며, 조명계획안의 적합성을 판단하기 위한 시뮬레이션 소프트웨어는 Lumen-micro 2000, Relux 2006, Lightscape 3.2와 AGI 32 등이 있다. 이러한 시뮬레이션 소프트웨어는 측정값과 시뮬레이션 결과값, 그리고 소프트웨어별 시뮬레이션 결과값이 상이하게 나오는 경우가 발생한다. 따라서 본 연구는 임의의 조명기구 측정 배광데이터와 Photopia 2.0의 시뮬레이션 배광데이터를 비교하고, 공간의 규모, 배광데이터, 마감재등의 같은 조건하에 Lumen-micro 2000, Relux 2006, Lightscape 3.2와 AGI 32의 시뮬레이션 결과를 비교하여 차이점의 원인에 분석하고자 한다.

Recently, there are rapid increases in golf population. People are enjoying play golf not only during the day but also at night as well. Although there are not many golf courses that offer night play, people inquire place where they can play night games due to their busy daily lives. To supply the demand in national golf courses night-lighting has been pushed ahead competitively, however there are few standards of lighting design in golf course. Because it is not clear that the standards of lighting in the world yet, this study aimed at presentation of standard of lighting design for planning golf course. Investigating the cases of golf course, this study suggested illumination standard of golf course to support comfortable visual-environment and measures to prevention glare for visitors.

The not an organization a branch stream the maintenance factor class on a class and the roadway type for roadway lighting design, the facted an insufficiency maintenance factor to apply our the country conditions. The consideration of maintenance factors is not being fully applied for roadway lighting design in Korea. This paper consider optical characteristics and maintenance factors as well as LID of Luminaires in designing roadway lighting. Consideration of maintenance factors that are neme specified according to LDD(Luminaire Dirt Depreciation), LLD(Lamp Lumen Depreciation), AADT(Average Annual Daily Traffic) based on IESNA regulation. The analyzed optical characteristics are applied for stagger and cross roadway types with maintenance factors in the range of 0.51$\sim$1.00 and equipment factor of 0.9.

The purpose of luminance measurement in lighting design of urban scale is to prevent light trespass and light pollution, caused by over-bright. Specially, the illumination of road, tunnel and sports complex as urban infrastructure is measured by international standard for illuminance and luminance. It has been used the spot luminance meter and the image photometer to define the characteristics of qualitative and quantitative in exterior lighting. This study introduced the concept of HDR Image, procedure of HDR Image creation and analysis. Applications of HDR Image, particularly within the apartment building exterior lighting design analysis, have been demonstrated. The procedure proposed in this study is a affordable method that is useful for the assessment of luminance distribution in the scene with electric light. It also provides a measurement capability with the high resolution luminance data within a large field of view efficiently and quickly, which is not possible to achieve with a luminance meter.

The number of tunnel has fast increased with the rapid expansion of highway network. Tunnel should be designed to provide for drivers both safety and pleasant driving conditions. In this perspective, the design for tunnel lightning is very important in order to provide its safety, pleasantness, and cost-efficiency of maintenance, all of which should be considered and analyzed for a better tunnel lighting. This paper attempts to compare the low-pressure sodium lamp, which have usually been used for tunnel lighting, with the fluorescent lamp, which we consider as an alternative for the former. In an effort to determine the number of lamps to meet the required illuminance in the tunnel, this research employs a simulation technique which would allow us to conjecture, with the aid of basic model, the life cycle cost for illumination per each tunnel. This analysis is expected to provide a basic method and related information for tunnel development and design.

This study examines visual perception and spatial satisfaction according to lighting conditions. Field measurements and surveys were performed in three rest space of university buildings where various lighting conditions were employed. Results indicate that overall impression of space improved when low color temperature, such as 3,000 K governed overall lighting environment and accent lighting was used for wall surfaces. Lighting conditions that kept uniform illuminance levels using area light sources containing fluorescent lamps with 6,500 K failed to keep favorable spatial satisfaction for space. High color temperature was not recommended for lighting in rest space. Asymmetrical illuminance levels formed by low color temperature such as 3000 K is recommended to keep positive mood and improve spatial satisfaction in rest space. Overall impression of the space was influenced by visual comfort, color temperature, spatial satisfaction and brightness. Spatial satisfaction for space was effectively impacted by psychological comfort, color temperature and overall impression for lighting conditions. Psychological comfort in space was influenced by color temperature, spatial satisfaction and visual annoyance from reflected light.

The experimental study of the white LED lighting focused on the readability in interior space according to age group is conducted realizing importance of the lighting environment and necessity of lighting study depending on the user situation. The results of study represent that a teenager does not show sensitive reaction to change of the color temperature and illuminance. The people in 20s and 30s prefer neutral white LED lighting and are very sensitive to change of the light environment. The people in 50s and 60s prefer high illumination and cool white LED lighting series. People of all ages highly appraise 6000K of 700 lux and 4000K in the illuminance range of 700 lux to 1000 lux for readability. The white LED lighting of color temperature 4000K is estimated as a suitable environment for readability in a wide range of illumination.

In this paper, we propose a design for an efficient hybrid LED street lighting management system using standalone solar photovoltaic. The proposed efficient hybrid LED street lighting management system was composed of hybrid power conditioning system, gateways, LED street lights and a monitoring server. The hybrid power conditioning system was designed to charge produced power by solar photovoltaic panels in day time, and supply power to the LED street lights in night time. If there is insufficient power, the system was designed to operate using firm power, because the system utilizes photovoltaic power. A system control algorithm allied to the lighting management system, and experimented by being configured to the functions that are able to perform real-time monitoring and remote control through the lighting management system even when absent. In the result of the efficiency analysis of the hybrid lighting management system proposed in this paper, we were able to increase the energy efficiency compared to existing lighting control systems by reducing power consumption and electricity costs.

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.
