전 세계적인 에너지 절약 정책에 대응하여 새로운 고효율 LED 및 드라이버 IC의 출시가 활발하다. 단색 또는 칼라 LED를 사용하여 경관조명, 무대조명, 음악분수 등에 많이 활용되는데 다양한 전압 및 LED 구동 방식 등에 따라 LED의 수명과 비용이 달라질 수 있다. 또한 LED의 밝기 및 색상 등을 조절하여 멋진 연출을 위해 마이크로컨트롤러의 사용이 필수적이고, 다수의 장치를 함께 연동하는 경우에는 이들을 통신으로 연결하여 사용하는데, 본 논문에서 조명 장치에 표준으로 많이 사용하는 DMX512 통신 프로토콜, 몇 가지 정전류 구동 방식에 대해서 살펴보고, 저가격의 마이크로컨트롤러를 사용하여 DMX512 수신 장치를 구현해 보았다.

Stage lighting plays a significant role in drawing out the mood and images that are intended by the choreographer. It is related to the dancers' movements and affects them both directly and indirectly. This study is on a reciprocal relationship between dance choreography and stage lighting, covering a broad range of functional factors of lighting effects on the dance choreography. Also, the data on preferred lighting colours and their frequency of usage are gathered through surveys by lighting specialists. The data is used to identify the lighting colour in general dance choreography. It is collected to serve the purpose of providing opportunities to acknowledge the needs of various colour changes on the stage. It is hoped that a collaboration of studies related in this subject are continuously promoted and researched in producing high quality dance performances.

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.

A performance delivers the contents and feeling through human bodies and stage settings in the limited space of a stage. Among the stage settings, the lighting creates overall atmospheres effectively according to the situations of the performance such as a time flow, a change of seasons, an expression of the mental state of the performer. As the LED lighting is used more widely, the number and the size of the lighting is being decreased, which makes it possible for various devices to be used. However, just as conventional lighting devices, most of them are fixed. So it is difficult to use them at a blind spot and to replace them. To solve this problem, this article suggests a system which replaces lighting automatically and moves. As it can moved to a spot we want on a rail, and the lighting system can be replaced by itself, it can have various lighting effects, increasing the effectiveness of the performance. Additionally, it can also decrease the danger of a worker operating the lighting device located at a high place. At the mock-up experiment, its mobility and stability on a rail were tested using the wheel of the Modular Robot.

For the development of 100[W] stage lighting, quantitative and uniform color mixing that applied through color adopted Simple-Inverse matching so that color mixing can be possible along Black Body Locus. R,G,B(Red, Green, Blue) LED(Light Emitting Diode) arrangement through LED package character analysis, LED module, and the characteristic of device were considered for uniform color mixing. A distance changeable optical device was built to assure high uniformity and high diffusion of not only the middle of diffusion side but also the border side. Also, we developed the control power circuit that can expand up to 6 channels which are possible for quantitative color mixing, and the high uniformity and high quantified border light for color mixing control and the verification of color mixing characteristics by composing GUI(Graphical user interface) including color mixing simulator. By presenting the experimental results of light color control, we proved the usefulness of our developed border light and the proposed color mixing method.

A Study on the Stage Lighting Design by the Type of Performance Hall The purpose of this study is to inquire into the practice of lighting design which is changed by type of stage Proscenium Stage, Thrust Stage, Arena Stage, and Flexible Stage, which have originated from ancient Greek theatre and are still used in contemporary theatre. This studt takes a good at the practical application of lighting design to different types of stage, through which it is expected to improve the understanding of lighting as a part of performing arts and to develop the quality of stage arts. The way of lighting design by type of stage can be acstracted as the following. This is expected to be of a great help to stage arts as well as different lighting designs for each type of stage. The methodology of lighting design might have limits in its application to practice in the current war Id where theatre structures and lighting equipments are fast-developing and ever-changing. However, lighting design can develop based on the basic design concepts as the researches of all fields can develop by applying their basic theories.

This study analyzes economic feasibility of the LED lighting system compare to the halogen. To evaluate economic feasibility of the LED devices, we analyzed the size of theater, current value of the lighting devices in kinds, annual cost and annual cost according to the surface in case of designing stage lighting system with LED using WEELS 2011. Also, to compare energy consumption, we analyzed consumption and amount of electric energy by the surface and the amount of CO2 emission. Data showed that annual cost of the LED devices are highly inexpensive than halogen and now the value is of great. However initial cost of the equipment 200% higher than halogen. Though LED devices are expensive in startup setting, the value of utilization factor is large and depreciation years of LED(30years) are longer than halogen(2years). Therefore, annual cost of LED can make up the minus. Consider the tendency of reducing price of LED devices, we can assume that annual cost of the LED will be lower than halogen devices. Further, in 3years the expense of LED and halogen is reversed.
