Due to the development of technology, the modern people became to require not only more convenient life but also more comfortable and emotional environment, and individually suitable living environment is applied to residents in a residential space. Recently, while the LED lighting was variously attempted in every sector in society, it is needed to express differentiated lighting according to the resident's individual lifestyle in a residential space. In this paper, we analyze the role of LED lighting suitable for the digitalized lifestyle of the modern people through the relevant literature survey and case studies. The following results are obtained in summary of the rapidly changed recent trends of LED lighting. First, LED light replace existing light sources due to the advanced new technology in LED industry, and take the spotlight as a new lighting solution with the development of variable color LED bulb and the control technology by the wired and wireless communications. Second, LED lighting can be structurally applicable to every lighting device because of its compact and lightweight units, can produce abundant light environment by expression of variable colors and moods with the easy coloring and dimming control, can be reborn as emotional lighting design. Third, as recently practices are constantly appeared that integrate LED lights in the interior elements, such as object and furniture, and combine advanced LED lighting technology to new materials, the portion of illumination on the indoor environment is further increased after integrating the LED lighting and interior elements make boundaries of lighting and product architecture become blurred. LED lighting is confirmed that is being changed from the external functionality including material, shape, color, and etc. into the contextual emotion design including the lights expression, variable color, brightness control, making image, and etc. as the light source in current smart lighting era.

최근 그린 IT 기술이 이슈화 되면서 전 세계적으로 탄소 배출을 낮추고 에너지 효율을 높일 수 있는 환경 친화적인 광원에 대한 연구가 활발히 진행되고 있으며, 특히 고유가와 환경오염 등의 문제로 기존의 백열등이나 형광등을 대체하기 위한 새로운 광원으로 LED가 크게 주목을 받고 있다. 본 논문에서는 저전력, 고효율, 고휘도의 LED 모듈에 온도, 습도, 조도, 그리고 이동 감지 센서를 포함한 복합 센서 모듈을 조합하여 가로등을 지능화하고, ZigBee 모듈을 이용하여 가로등 간에 IT기술인 USN 망 융합을 통하여, 가로등 시스템을 중앙에서 모니터링하고 지역 특성에 따라 선택적으로 가로등의 점멸을 원격으로 제어함으로써 효과적으로 에너지 절약을 극대화할 수 있는 Ad-Hoc망 기반 LED-IT-Sensor 통합 가로등을 설계하고 구현하였다.
