The most ideal light source that has been adapted to man is sunlight, and thought about a time sunlight in a dark place a lightness necessary us. It becomes an edge that an artificial light source makes the light source that approached a sunlight in final most. However, hard for using the sunlight because of a wide area and space need. Therefore, the light source that considered the characteristic light source use local and a color rendering, a life, the efficiency is developed. I analyze a light characteristic about Neodymium Lamp in this paper, and High efficiency recognizes a possible way

건축물이 다변화와 첨단화를 이루는데 반하여 이들 심장부인 변전실의 크기 결정이 합리적이고 효율적으로 이루어지지 않고 있어 증설 및 부하급변에 대응하지 못하고 있는 실정이다. 적절치 못한 결정은 건물의 기능을 제대로 할 수 없는 중대사인데도 불구하고 선정요건을 고려시 순번의 맨 마지막에 공간을 확보하는 경우가 있어 이의 합리적이고 효율적인 대책이 시급하다. 이를 위해 사례분석을 통한 제 요소를 분석하여 그 대책을 강구한다. As the new large buildings are continuously being built with the advanced technology and skills, an adequate size of electric room needs to be obtained so that engineers establish an efficient and reliable system in the electric room. Considering the current capacity, its expansion and its connecting system, the final size of it should be determined in order to bring an effective use of the building. Therefore, it is important to have the exact method of calculating the effective size of electric room, the heart of the building, especially when the value of land price is very high. In addition, it should be calculated in an accurate way due to the diversification of the system and the compact size of the electricity equipment. However, the research on this area and the comparison and evaluation of the size after construction have not been made enough and the results of them have not been applied when calculating a new size of electric room. Accordingly, this study examines three methods prescribed in the standards of electricity installation technology through case analysis and suggests substantial data by system, capacity, and purpose.

교통량의 증가로 인한 물류이동 및 도로망의 확충은 산업발전과 더불어 중요한 요소 대두되고 있으며 지자체의 활성화는 그 지역의 도로망과 연계되어 있어 노선의 직선화 및 자연훼손 감소를 위하여 터널의 설치가 점증하고 있다. 2003년까지 약 300개소의 터널이 증설될 예정이며 이에 대한 유지보수 및 안전상에 많은 주의가 필요하다. 이러한 터널의 설치는 많은 운전자 시야의 적응에 따른 여러 가지 복합적인 요소를 내포하고 있어 터널내의 교통사고는 대형사고로 이루어진다. 이에 대하여 본 논문에서는 터널 내 ㆍ 외에 휘도 센서를 설치하여 조명비로 인한 밝기가 비례적으로 설정되어 안전운행을 할 수 있는 시스템을 개발하고자 한다. Until the first stage of the 1990's years, Korea are not concern so mulch the facilities of traffic tunnel, because of them are the short length and also the quantity of them are not over the several tens in korea. but in latest many tunnels has been constructed and are designed in expressway and local national loads. the government office concerned forecast the numbers of tunnel are increased about 300 until the 2003 years, and then we need more interesting about the facilities of tunnel. in the tunnel, the first above of all important facilities is lighting installation which are required much electric energy and continuing maintenance.

Based on the past design data for electric power load and method of calculation, it is known that in general electric power load has been estimated excessively. For the accurate calculation, it is important to reflect in estimation of a total load capacity and the rated capacities of mechanical pump to be installed in buildings and motor to be actually provided. Various data for electric machine load have been published by Rules for electrical indoor installation, Korea Housing Corporation, KEPCO, Institute of construction technology, and NEC. However, these are very common standard data and far from power capacities actually utilized. As allowance rate of motor and its efficiency is getting improved, load capacities are expected to be lessen. This study has been focused on the selection of optimal electric machine load, which makes a lot of portions of load in the building.

This paper is to present the reflector design to have an optical function can increase illuminance, and be able to light distribution curve control. Generally, compare used painting type to German Alanod4, Alanod6, and illuminance brings the results to darken, and reflector must be studied in energy saving a few dimension by a little reflection factor. Also, a way to be able light up an available piece intensively is necessary in the light distribution curve side. In this paper FPL(Fluorescent Lamp P-type) suitable for a tunnel with 3-24W, and verification does a characteristic of the slim lamp which did reflector to the center.

Recently, one of the most important issues to the front is the use of sunlight due to the rapid increase of energy demand and the importance of environment. Sunlight can be used by various means such as for the underground lighting, artifical lighting the plants and the fishes, etc. In this paper, I will present lighting method for the use of sunlight, spectral analysis of sunlight and sunlight collector system's light. In addition, I'll search for the optimum distance to get the visible light.

Lighting in the tunnel makes for safe driving of cars taking into account of change in perception arisen in the sight of drivers of cars entering into and passing tunnel, drivers mental reaction and unique circumstances of a tunnel. There are many variables to satisfy safe driving in the tunnel. Since tunnels are mostly located in the mountainous area and illumination at the approach part differs largely depending on the surrounding circumstances, a standard different from that of common lighting is applied. An accidentin the tunnel, which involves same danger as in underground, may lead to a large mishap. Therefore, control by sensors inside and outside of tunnel ensures prevention of an accident through control of illumination at the approach part and inside of tunnel. It is very important in the aspect of saving energy since such control is available to reduce depreciation factor resulted from early excessive intensity of illumination.
