This paper developed new manufacture process technology of slim type flexible flat lighting product used lower power white LED. Flexible flat lighting is applied to letter sign lighting, traffic lighting, interior wall lighting, flat lighting, aquarium back lighting, wreath light etc. Main manufacture process technology were developed drawing software for electronics circuit, inkjet electronic circuit pattern and inkjet white ink coating. For pattern printing it was utilized for piezoelectonic inkjet head printing technology. Also high vacuum pressure laminating technology was waterproofing for LED flat lighting protection. Hence, form process technology we were manufactured for flexible flat lighting product of the power 12 W, input voltage 48 V and plane size $480{\times}480mm$. It acquired a these validity from experiment results.

Daylight is regarded by most people as preferred light source for interior lig-hting. With poper design, daylight can save electric lighting during daytime. This paper attemptes to show that bett-er use of daylight might be the balanced use of supplementary artificial lighting at times and places where the natural 1-ighting is inadequate with consequent c-ost and energy saving.

In this paper, an automatic lighting control system is developed using microprocessor. The developed system consists of a digital lighting control unit, an analog lighting control unit, and a lighting control simulator. In the developed system, ATMega128 is used as the main controller. The developed digital lighting control unit consists of eight modules and the developed analog lighting control unit consists of six modules respectively. Additional, the developed simulator consists of a digital and an analog lighting control simulation using graphic user interface. And so this developed system can be applied to the controller design of the interior and exterior lighting equipment.

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.

The purpose of this study is to identify the perceptual differences among independent elderly relative. to falls risk associated with specified environmental design factors. The sample consisted of 135 independent elderly who live in Ulsan. The data were collected by utilizing questionnaire which included demographic information, and environmental design assessments accompanied by line drawings. The data were analyzed by using SAS program. The major findings were as follows: (1) There were 35(25.9％) elderly experienced fall(s) within one year and about half of the fallers fell more than once. (2) The elderly perceived lighting is the most hazardous interior design factor related to increased risk of falls. (3) There was a significant difference among age groups on perception of lighting as interior design factors and the elderly perceived differently floor as interior design factors by their perceived health status.

We human beings can only retain our normal consciousness and the power of thinking through the continuous transition of environment.. Lighting have been progressed inaccordance with these requirements and the demanding functions of our life style which played the important roll of bringing the stimulation we need with the new methods of performances, The advanced technology of today introduces the new method of combining the light, art and the Hi-technology into our artistic world bringing the new stimulation we have not experienced before. It is becoming the point of issue how to use these newly developed techniques and utilize, especially to those who are involved in the illumination environment and the world of Interior Design.

The main consumers of wedding market are young people. They prefer differentiated and unique wedding and with the deregulation of using five-star hotels as wedding spaces in 1999, the wedding market has entered into an era of new competition. Under the background like above, this study tries to provide the basis for the effective and systematic interior coordination of wedding spaces. For this study, large banquet halls at 16 five-star hotels in Seoul were selected. Theoretical and field examinations, and interviews were conducted. The elements of wedding space include the architectural elements of floor, walls, and ceiling and lighting, color, fabric, table setting, and flower coordination. This study found that uniformity or repetition is used for the walls while modules are used for the ceiling. Unlike the past, LED is used for lighting to create diverse colors and the range of colors used has been broadened. In addition, fabric, table setting, and flowers are used actively to create overall atmosphere of the space. When these elements are aggregated and analyzed by hotel for interior design style, Hotels H and S have modern style, Hotels L and P have elegant style and Hotel IP have classical style.
