  • 선박용 형광등기구는 설치되는 위치에 따라 매입형, 노출형, 램프 수에 따라 2등용과 3등용, 글로브형태에 따라 투명, 반투명으로 분류된다. 본 논문에서는 기존 형광등기구를 LED 조명기구로 대체하기 위한 기초 실험으로 선박내 일반조명으로 가장 많이 사용되는 매입형 형광등기구의 소비전력, 총광속, 색 온도 및 빔각 등 전기 광학적 특성을 분석하였다.

  • This study is intended to compare physical properties of fluorescent luminaires with ones of LED luminaires so as to analyze fundamental characteristics of LED luminaires. For this, a comparative analysis of uniformity ratio of illuminance and luminance distribution of these two luminaires was made, and materials for applying LED luminaires to interior construction space were prepared. This study was carried out in four stages. First, a theoretical review on LED illumination light source was made compared with the existing luminaires. Second, a mock-up to control experimental variables to meet the objective of this study was manufactured. Third uniformity ratio of illuminance and luminance distribution of each luminaire were measured by using the mock-up. Fourth, a comparative analysis of uniformity ratio of illuminance and characteristics of luminance distribution of the existing fluorescent luminaires and LED ones was made. As a result of the study, the uniformity ratio of illuminance of LED luminaires, 0.559, was higher than one of the existing fluorescent luminaires, 0.522. Namely, it was shown that illuminance distribution of LED luminaires was uniform and global diffuse was good. As a result of measuring luminance distribution, it was found that luminance distribution of LED luminaires was more uniform than one of the existing fluorescent luminaires. The maximum luminance of fluorescent luminaires and LED luminaires over the wall was $180.6[cd/m^2]$ and $155.26[cd/m^2]$ respectively. Namely, the maximum luminance of fluorescent luminaires was higher than one of LED luminaires. The average luminance of fluorescent luminaires and LED luminaires was $44.32[cd/m^2]$ and $58.65[cd/m^2]$. Like this, the average luminance of LED luminaires was higher than one of fluorescent luminaires. Considering these results, it's thought that LED luminaires can give a person in the room a more comfortable working environment than fluorescent luminaires.

  • Recently, the circuits of fluorescent light-switches are separated for window-light, middle-lights, or corridor-light, etc in most offices and classrooms in this country. Although it is clean and shiny - more than standard intensity of illumination, it is common that fluorescent lights on the side of window are lighted. In this case, we can use a fluorescent light with a sensor, which is turned on and off automatically according to the amount of sunlight. I think that this plan can save energy, reduce the budget, and increase the effect of education. and so I studied on this plan.
