공간의 효율적 조명시스템의 설계를 위해서는 그 공간의 물리적 조건들과 작업의 내용 등을 고려하여 표준적인 상황을 규정하고, 그 상황에서 가장 유용한 조명설계를 찾아내어 표준화해야 한다. 특히, 인텔리전트 빌딩에서는 OA도입으로 인한 VDT 작업환경, 취업인구의 고령화 등의 공간특성을 고려한 조명계획이 요구되며 이러한 조명계획을 구현할 수 있는 조명기구를 제작할 필요가 있다. 따라서 이 연구에서는 국내 인텔리전트 빌딩의 주요공간별 크기와 형태 및 특성을 조사하여 표준공간을 선정했고, 이를 반사판 설계에 반영하여 3가지 형태의 형광등기구를 설계, 분석하였다.

To identify energy savings when comparing lighting designs or evaluating installed lighting, it is necessary to analyze the consumption of lighting power with respect to the electricity consumed and the lighting area. In Korea, however, these factors have not been considered in lighting design. In this paper, the lighting power-related standards on indoor lighting in foreign countries have been analyzed. It is determine appropriate lighting power consumption for indoor by calculating the energy consumption has been estimated in a lighting design adopted domestic luminaire used.

Recently, as development of the luminaire industry, many people are interest of the outdoor and indoor lighting environment. Also, as increasing of people activity at night, the role of lighting is more important. In these days, the issue of LEDs lighting environment is using loud colors of LEDs which are the most of primary colors (R, G, B). It is often disliked by same people. Therefore, it is necessary to use of natural color in lighting design using LEDs. The colors of the LEDs are composed of combination of R, G, B diodes. This paper performs to investigate preference of various colors and color patterns of LEDs. The purposes of this study are to suggest standardization and natural colors instead of primary colors using LEDs.

We proposed 50W-LED modules of using Heat-pipe and Stack-fin and produced LED modules was evaluated heat dissipation characteristics with comparison of the conventional die-casting type. It verified the application of products by applying it to 150W-LED road luminaires through simulation. The LED module was measures aimed design temperature of the Stack-fin and showed 26% upward heat dissipation effect than a conventional die-casting type. The luminous efficacy of 150W-LED road luminaires using this LED module reached over 112lm/W, and the simulation results showed average of horizontal luminance, overall luminance uniformity($U_O$) and lane luminance uniformity($U_I$) that is suitable for five-lane road with the KS standards.

도로의 난간에 설치되는 조명기구에 의한 불능글레어의 영향을 가로등 조명방식과 비교, 평가하고 글레어 규제를 위한 적정 휘도 범위를 알아내기 위한 시험을 수행하였다. 실내에 시험실을 구축하고, 글레어 유무 시 휘도대비식별역의 변화를 평가하였다. 글레어 광원에 의한 망막조도가 증가하고, 좁은 시야 각 내에 글레어 광원이 존재하면 휘도대비식별역이 증가하였다. 그리고 낮은 위치에 설치되더라도 시야에서 벗어나 있다면 가로등 조명방식에 비해 불능글레어의 영향이 적은 것으로 나타났다.

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.

Solar daylighting system provides free and comfort lighting, but its cost has been key issue due to difficult design and control of the heavy light collecting system. One of the solutions for the heavy design issues would be using a light framed film such fresnel and prism lens. Prism light guide luminaires have for some time been used to distribute light when it is desirable to have remote light sources. These systems are helpful when it is desirable to have fewer light sources, and/or to position light sources in places where lamp maintenance is easier, or electrical hazard is reduced. This proposed prototype system consists of light collector, light transformer and light pipe.

Until now, dimmable fluorescent luminaires has been widely used for dimming systems, and LED is currently attracting attentions as a alternative lamp due to environmental problem issues. LED, one of eco-friendly high efficiency lamp, has advantage that dimming is easy than fluorescent luminaire. But there have been not enough research on technical development and application for LED dimming. Therefore, to analyze luminous quantity of dimmable LED, the illuminance, color temperature, luminance, and current were measured in the whole range of dimming. In the results of this study, the dimmable LED of various types showed a similar trend in the changed luminous quantity by dimming.

In recent, there have been several developments in lamp technology that promise savings in electrical power consumption and improved quality of the lighting space. Above ail, the advantage of ring-shaped electrodeless fluorescent lamp is the removal of internal electrodes and heating filaments that are a light-limiting factor of conventional fluorescent lamps. Therefore, the life time of ring-shaped electrodeless fluorescent lamps is substantially higher than that of conventional fluorescent lamps and last up to 60,000 hours and is intended as a high efficacy replacement for the incandescent reflector lamp in many applications. In this paper, when appling the electrodeless lamp in luminaire, We analyzed change of optical and electrical characteristics.

As we know, topography of korea is composed of many mountains Also, the volume of traffic is increasing more and more nowadays. So, many tunnels are being constructed to reduce cost of transport and time. Thus, tunnel illumination was considered as the most important thing to make safe traffic conditions. In the past, we installed luminaires on the wall in tunnel, but currently we are installing those on the ceiling. Wherever luminaires are installed on the ceiling, the electric designer may not have known the proper point to install luminaires. Therefore, we researched this project to resolve above problems with abundant experience and accurate data through simulation(Lightscape program).
