Nowadays, the lighting of urban nightscape has become important for improvement in city. Lighting the outdoor is different that lighting an interior. Outdoor lighting designs should be designed to minimize glare, light trespass, light clutter and energy conservation to avoid light pollution. Mokpo city launched into a large scale project of the city beautification using outdoor lighting. However, outcomes of outdoor lighting project have faced strong opposition from environmental groups. This study aims to analyze the light pollution of outdoor lighting in Mokpo-si for creating a health night environment. The Radiant Imaging Prometric-1400 was used to measure the luminance of Yudal Mountain, Goha Island and Luminarie Street. The result showed that the all the outdoor lighting produce light pollution and some places like mountain and island did not need a lot of lighting all the time.

Although the Act on the Prevention of Light Pollution Due to Artificial Lighting has been enforced since 2013, the area of advertisement lighting has made slow progress in solving the problems of light pollution. This paper first investigated institutional problems by analyzing domestic laws and regulations relating to the light pollution of advertisement lighting, and investigated and analyzed methods for reducing light pollution that were applied in overseas countries. Then, problems of light pollution were analyzed by conducting a research on the actual status of advertisement lightings installed in South Korea and applying various methods for reducing light pollution, and advertisement lighting using LED was recommended. As a method for reducing light pollution that can be applied to the process of manufacturing channel letter-type advertisement lights, power consumption per unit area ($W/m^2$) was proposed, and $100W/m^2$ was recommended as a value currently suitable for South Korea.

This study aims to suggest some problems, which occur when environmental lighting zone is set by use-zone only, by comparing and analyzing the artificial illumination luminance. In addition, this study aims to review the control standards of light pollution and to suggest a practical environmental lighting zone-setting method. I checked out the standards of average surface luminance and luminance contrast as for light pollution management. In addition, I did some research on evaluation of light pollution on surroundings based on investigation of use-environment as for lighting environment setting method.

This is a study to establish regulations against light pollution for lighting on roads. Many kinds of light pollution by luminaire on roads was calculated and analyzed by applying the classification method of luminaires(Cut-off classification of IDA-IESNA, BUG Rating Classification) and the calculation method of Upward Lighting Ratio of CIE among measures to prevent light pollution that international lighting organizations suggest. As a result of the analysis, it was found that the regulation by Cutoff of IESNA and ULR classification of CIE could be one for scattered light of light pollution compared to BUG classification but is not sufficient for the regulation of light tresspass or glare. BUG classification by each lighting zone was suggested as threshold value of the light pollution regulation considering domestic conditions.

The problems of light pollution first became an issue in the 1970s when astronomers identified the degradation of the night sky due to the increase in lighting associated with development and growth. As more impacts to the environment by lighting have been identified, many attempts have been made for reducing light pollutions. To prevent light pollution and increase energy efficiency, Seoul Metropolitan Government(SMG) replaced metal halide road lighting to LED luminaire in four arterial highway in Seoul. The present study compared the lighting characteristics of metal halide and LED luminaire in terms of Korea Standard for road lighting(KS A 3701) and BUG rating from Illuminating Engineering Society of North America(IESNA). The results showed that LED luminaire increased road surface luminance up to 2 times in average compared to the metal halide environment. Also, LED luminaire reduced the glare value by 2 times and luminous flux over 50% than the metal halide luminaire. In comparison with the BUG ratings, LED luminaire rated 1 degree lower for the backlight ratings and 3-4 degrees lower for the uplight ratings. The measured values testified that the LED luminaire is effective for roadway lighting and light pollution reduction.

환경오염과 에너지 절약차원에서 세계적으로 빛도 공해의 하나로 인식하고 각 나라에 맞는 법규와 규제 방식을 정하여 옥외조명을 관리하고 있다. 반면 국내에서는 광해 대책 안이 미비한 실정이다. 따라서 본 논문에서는 국내실정에 적합한 규제안과 광해 계산법을 마련하기 위해서 국제 조명단체들이 제시하는 광해계산법을 조사 분석하였다. 또한 여러 도로조명기구들을 선정한 후 광해계산법과 시뮬레이션 프로그램을 적용하여 광해요소들을 비교 분석하였고, 결론으로 우리나라에 맞는 광해 규제안을 제시하였다.

There have been light pollution standards just for architectural lighting and sign in the "Light Pollution Abatement Law" so far. However, both of them regulate only one of the three main light pollution elements-"Glare". Therefore, it is imperative to do research on the other two light pollution elements-"Upward" and "Light Trespass" and make proper restriction. Subsequently, this study focuses on the upward light from the street light and suggests its analysis method. Eventually, this study aims to make viable management which is suitable for the nation and, in addition, to suggest appropriate level of restriction to "Light Pollution Abatement Law" by doing site survey.

As issues on light pollution is being raised recently, movements to prevent light pollution is being implemented by each local government, such as by enforcing the Light Pollution Act from February 2013, in order to require compliance with the light-emitting permission level of existing lighting facilities. However, despite the regulations, no specific measures on products are being prepared. Thus, this Research has designed a light shield as a measure to minimize the burden of the effectiveness and time required for development and the burden of the cost necessary to re-install existing light facilities in its entirety and reviewed the effect of the measure through the BUG ratings.

우리나라의 경우 최근 경관조명의 중요성을 인식하고 많은 건축물과 광장, 조경, 역사적 모뉴멘트 등에 옥외조명이 설치되고 있다. 특히, 최근 쇼핑용 복합건물들은 옥외조명을 설치함으로써 건물의 인지도를 높이고, 그에 따라 매출을 증대시키고자 한다. 그러나, 대형 쇼핑용 복합빌딩에 옥외조명을 과다하게 설치함으로써 광공해를 발생시키고 있다. 이미 광공해에 대하여 선진외국에서는 조명조례와 광공해대책가이드 등을 제정하여 쾌적한 조명환경을 구축하려고 노력하고 있다. 이에 본 연구는 주로 야간에 많이 이용되는 3개의 복합쇼핑 빌딩에 설치된 옥외조명의 광공해의 발생 실태를 조사하였다. 이를 위하여 건물의 표면휘도, 보행도로의 수평면조도 및 연직면조도를 직접 현장에서 측정기구로 측정하여 CIE기준과 비교하였으며, 연구 결과는 다음과 같다. 전반확산형조명기구가 보행도로에 설치됨으로써 눈부심이 부분적으로 발생하고 있으므로 cut-off 조명기구를 설치할 필요가 있는 것으로 나타났다. 또한, 건물외관의 옥외조명은 건물의 인지도와 광고를 강조하기 위하여 휘도값을 크게 설계한 것으로 나타났다. 즉, 도로에 면한 건물표면의 측정휘도값이 CIE기준과 비교했을 때 2배정도 높게 나타났으며, 보도의 연직면 조도비도 권장값보다 크게 나타났다. 아직 우리나라의 경우 광공해에 대한 기준이나 가이드가 없으므로 이에 대한 대책이 절실히 필요하다.

To suggest lighting regulations to prevent light pollution, domestic and international standards were analyzed and the luminance of outdoor signboards of main street at night was measured. In addition, to regulate the methods of luminance measurement, experiments on the measuring distance and direction from the signboards were conducted. The regulations were set as maximum luminance for outdoor signboard lightings of channel letter type, and limitations were suggested on each of the four lighting zones.
