Lighting in a fashion shop has an effect on customers, highlights the products on the shelf, and has become more important. Even though lighting has a significant effect on customers, the studies on fashion shop lighting have primarily focused on how to create lighting which can influence customers' purchase behavior, and their awareness and expectation. On the contrary, it's been hard to find a study on a quantified fashion shop lighting plan considering customer confidence. In a current fashion shop lighting plan, display lighting is planned indiscreetly. Therefore, this study conducted an investigation of the light environment of the current fashion shop and museum exhibits lighting. Through such processes, the possibility of applying fashion store display lighting environments was investigated. Finally, for the assessment of museum exhibitions lighting applying fashion store display lighting environments, a subjective evaluation method using light simulation was proposed.

This field study was conducted to survey the effect of seating ＆ lighting conditions on work. The results were as follows ; Discomfortable parts of body caused by unsuitable sitting postures on work were low back 52.05%, leg 15.75%, neck 14.38% and arm 9.59%. Work conditions of sitting postures were needed arm rest, back rest of seat and adjustable seat height. Effect of work efficiency by lighting conditions were statistically significant relationship between glaring state of workstation and lighting state.

The research measured 14 spots including four streetlights, five public buildings, and five officetels to obtain data needed for the improvement of townscape, grasping the characteristics of the design of landscape lighting of Dongdaeguro in Daegu Metropolitan city. The result of the research shows that landscape lighting by outside lightings of buildings had almost no effect and also it was formed with darker landscape lighting due to high buildings that had no effect of outside lighting. In addition, landscape lighting by streetlights have no unity due to different management facilities of the lightstreets.

This study examined the P Church in the Large chapel and S Church in the midium chapel were Analyzed to the installed stage broadcast lighting system. As a result of the installation of lighting equipment of LED class in P Church in the Large chapel, it provided clearer image and did not have shadow. While tungsten halogen illumination was very hot and heated to be preaching, LED was not heated so the pastor was very comfortable for preaching. S Church in the Midium chapel due to low ceiling height using LED lighting musical, theater and possibly were directed. If a similar structure of Dae-Hak Street theater to replace the existing fixtures by LED lighting, rendering effective and energy saving effect is thought to have much effect.

This paper analyzes the effect of the energy saving and evaluates the economics using High Efficiency lighting. About 18 percent (17,000GWh) of total power demands in Korea m consumed i]l the lighting field. There isa lot of energy potential that can be saved because the power demand isolwer relatively than the others parts. The existing lighting that its length and electric energy are 32[mm] and 40[w] can alternate with high efficiency lighting which its length and electric energy are 26[mm] and 32[w]. Two Lightings is measuring the illumination and the electric energy and then are analyzed into the effect of the lighting saving by measurement.

Designing outdoor lighting on landmarks has been activated in Korea since 2002 World Cup. And outdoor lighting has been important method to create nighttime activities. Especially, historic buildings which are illuminated by outdoor lighting expresses cultural beauty of the heritages in the region. Therefore, this study aims to analyze the outdoor lighting effect of historic buildings with particular reference to four historic buildings - Namdaemun, Kwanghwamun, Changanmun and Paltalmun. For the purpose, luminance of outdoor lighting are measured. Outdoor lighting of the historic buildings were mainly illuminated by the floodlights. In addition, up-lighting and accent lighting were used for expressing the bracket structure. Basements and rooflines are emphasized by floodlighting, and they represented the night image of historical buildings. For the subjective evaluation on the outdoor lighting of historic buildings, outdoor lighting images of four historic buildings - Namdaemun, Kwanghwamun, Changanmun and Paltalmun were photographed. Questionnaire surveys were conducted by hundred and twenty university students of architectural department And collected papers were statistically analyzed by SPSS. Factors that shows outdoor lighting images of historical buildings are as follows; atmosphere, clearness, intimacy, modelling. On the question of general impression of outdoor lighting, Kwanghwamun has got the most satisfactory responses and the next is Changanmun and Namdaemun, Paltalmun. Major variables which related to the 'general impression' of outdoor lighting for historic buildings have been 'dignity', 'match', 'elegance', 'beauty' in the order.

In this paper, We has been studied the lifetime degradation of LED lighting system compared to MH lighting. Especially the effect of temperature level on the lifetime degradation has been investigated. The results show that temperature plays a role in the lifetime degradation and slope of degradation line represent as temperature level differently. However, It is possible to estimate the lifetime of LED lighting system using equation induced the slope of degradation line.

본 논문에서는 최적의 에너지 효율을 위한 새로운 LED 조명기기 점등제어 알고리즘을 제안하였다. 제안된 점등제어 알고리즘은 다중센서를 기반으로 주변 조도를 측정하여 LED 조명기기의 전원부를 제어하여 에너지를 절약하였다. 또한 점등된 시간동안에는 팔각형 패턴으로 점등을 하게 되고, 일정시간 간격으로 패턴을 반전시켜 점등제어를 하다가 모션 센서에 의해 움직임이 감지되면 전체 LED는 점등하도록 설계하였다. 그리고 실시간으로 센서들로부터 측정된 정보를 Zigbee 무선 네트워크에 의하여 중앙관제센터와 통신하여 원격으로 관리제어가 가능하도록 설계하였다. 본 논문에서 제안한 점등제어 알고리즘은 에너지 절감 효과를 입증하기 위하여, 점등제어 프로그램을 이용하여 LED 조명기기의 점등 상태에 대한 전력 소비를 측정하였다. 측정한 결과, 기존의 점등 방식보다 제안한 알고리즘을 적용한 점등방식은 약 40% 이상의 에너지 절감 효과가 있음을 입증하였다.

This study suggests the optimum interior environment by projecting the criteria to design the living space light-ing that select the lighting environment among the sever-al environmental factors that influenced on the human perception. As a correspondance between the visual perception and the lighting, visual perception process, vision system, and visual perception system are investigated to compre-hend the lighting, and then conceptual contour of the lighting environments are presented which are transmit-ted the visual informations. As a lighting factors which are influenced on the visu-al perception, light source color is analized. Foundationally, the effect of the lighting methods and the techniques are investigated, and the changes of the lighting methods which influences on the space perception are examined through the previous results. As the changing the light sources color, the changing the subjective feelings of space perception through the ex-periment. This study is concluded with the proposition of the ef-fective lighting and the importance of the lighting envi-ronment.
