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.

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.

This study is to investigate the utilization of Indoor Proscenium Stage Zone Lighting method in the dancing performance. In other words, it is about how we can utilize the principle of zone lighting in dancing performance, a kind of stage art. Stage lights give lights on the stage. Therefore they play big and important roles in dancing performances. Lightings make big influence on the overall atvosphere and situations of the dancing work but most of dancers do not perceive their importance and furthermore they don't know about the lightings very well. To let them know about stage lightings better, we studied lightings form the perspective of the dancers who face the lightings without great knowledge thresh the articles and literature related general lightings and lighting design, books related to stage lightings and dancing lightings, previous studies and academic articles. The most important part of this study is to understand and utilize the principle of zone lightiing. Zone lighting is generally called as cross lighting, which means single light from the crossed two lights. When looking into the principle of the zone lighting of the Indoor Proscenium Stage, it means 45 degree lighting from both sides of the top form the point of the dancer When more than two lights are used, the angle of the light should be $90^{\circ}$or 120. It is the principle of the lighting technology showing the face and body of the dancers ing three dimension. Applying for the principle of this zone lighting to the dancing performance of Indoor Proscenium Stage, the lighting methods and the usage of the lightings were studied. As shown above, the role of the lighting is very important in dancing configuration. We hope that the perception on the dancing lighting will be changed and studies on the dancing lightings. By understanding and applying more principles of lighting, we will make efforts to make better dancing performance and dancing conporsers and dancers shall make more efforts and studies on lighting for better works. Through such efforts, we can have more experts and professionals In dancing lighting field and they will help us to describe and express the intention of the dancing work better as dancing artists. We hope that there will be better quality performances through more and diversified studies in this field.

Stage art basically builds upon the essence of "seeing," and at the same time, possesses relativity in showing and seeing. Stage lighting uses artificial light to solve the essence of "seeing", which is the foundation of stage art, and coming into the modern age, its role has been enhanced to an important medium for visual expression in stage art, due to the lighting tools that developed at a rapid pace along with the discovery of electricity, as well as the development of optics. Therefore, not only does lighting use a medium known as light in a field of stage art that gives mental and emotional inspiration to the audience, and aesthetically expresses time and space. In other words, stage lighting is a complex function of light engineering (technology and science) and aesthetic sense (feeling and art). This study aims to do research on methods for the visualization of stage space through lighting, mainly focused on dancing. I have studied the basics of stage lighting, its relations with other fields of stage art, and the functions and characteristics of lighting. Results show that lighting could be used to maximize the visualization of dancing and emphasizing the artistic growth of lighting and its ability to aesthetically express and I came to the following conclusions. First, lighting uses the forms and directions of light that various tools are able to produce in order to visualize the space on stage, and can maximally express the image that the work seeks. Second, it is possible to use lighting, through the movement of light, as a visual representation of the configuration of space in dancing works. Third, through the expression of visual and spatial aspects created by light, the work's dramatic catharsis can bring out mental and emotional feelings form the audience. Fourth, lighting can be seen not as a supporting role, but as an original visual design. To conclude, in order for lighting to be freed form the simple function of "lighting up the stage," which a majority of people think is common knowledge, and grow as one area in art, lighting designers must understand the intentions of the choreographer and the work with creativity and artistry they must consider light and color as an aesthetic language in order to heighten the effects of the work and allow it to partake as one element of work creation, so that lighting will be treated as a form of art.

We address the problematic issue of blinking in residential LED lighting systems-a phenomenon that has recently become a significant concern due to voltage sags caused by high-power household appliances. To combat this, we developed a two-stage LED converter with integrated anti-blinking circuitry, specifically designed for T5 LED indirect lighting fixtures. The first stage employs a Power Factor Correction (PFC) boost circuit to enhance voltage stability by aligning the voltage and current phases, thereby minimizing power losses. The second stage, a meticulously engineered DC-DC buck converter, ensures stable lighting despite electrical fluctuations. Rigorous testing has confirmed our converter's efficacy in maintaining consistent light output without blinking, thereby substantially improving user comfort and adhering to strict standards for harmonic distortion and electromagnetic compatibility. Our breakthrough provides a robust solution to a pressing issue, marking a significant advancement in LED lighting technology.
