As the economic growth achieved and the straight road was increased. so, the tunnel built more than before. In these days, lighting of tunnel entrance is important for safety and comfortable driving. Most of the tunnel lighting depend on artificial lighting and they use a lot of energy. In this paper, as a research for illumination improvement and saving energy at tunnel, reflecting mirror system is suggested. The performance of the system was evaluated with respect to various aspects. By applying a reflective mirror system, tunnel lighting and environment can be improved. This study is a preliminary study for developing a system to save energy of tunnel artificial lighting.

본 논문에서 수정 설계 및 선반의 주된 특색은 기존의 빛선반보다 3차원적인 각도 조절이다. 따라서, 바사광을 항상 천정 중앙부에 위치, 실내 휘도 및 조도의 변화를 줄였다. 또한 주광 활용시간을 1.5배 늘여, 이용 효율을 높였다. 기존의 Passive type의 빛선반보다 풍압 대처나 야간의 실내 조명 효율을 높이는데 활용이 가능하다.

In this paper, we propose an efficient control system for intelligent LED indoor lighting. The proposed an efficient control system for intelligent LED indoor lighting were included to elements such as daylight intensity measured through the PIR sensor and illuminance sensor at lighting style by the schedule defined and the occupancy detection. And it was controlled lighting through to the wireless sensor network, and was designed for the energy savings. Also, the lighting control of indoor lighting based on occupancy detection detect fine movements using a PIR sensor. And an unnecessary lighting intensity control of the window-side and the inside were controlled according to daylight level measurement result using the light sensor. In daylight inflow many case, the window-side lighting was to automatically darker, and in daylight inflow less case, was designed to be automatically bright. The efficiency validate results of an efficient control system for intelligent LED indoor lighting, the brightness of the indoor light were to maximize the energy saving by controlling in real time when entering as indoor a little that external lighting or daylight.

Thanks to the shift in awareness of environmentally friendly energy and government initiatives, practical light-emitting diode(LED) lighting fixtures have emerged and are being distributed, resulting in very large energy savings. However, in actual use of LED lighting, it is possible to use it as an individual, but when using a large street light or a whole home lighting, the whole lighting system is realized due to various problems such as efficiency, stability, and reliability. Doing so has several problems. Although AC-LED has been developed recently to solve safety problems such as heat generation phenomenon of the conventional DC-LED, it also has various problems such as quality safety and reliability, which are difficult to use as outdoor lighting using existing AC Power. This happens. Accordingly, the appropriate power for AC-LED should be developed and applied, and the emergence of such LED lighting will play a role as a tool that can overcome the limitations of existing LED lighting and implement sustainable energy saving.

세계적으로 에너지 과다 사용으로 인한 비상사태가 발생하면서 에너지 절감, 그린 에너지에 대한 관심이 증가하고 있다. 특히 블루투스 기반의 네트워크 구성을 통해 중앙 조명 제어가 이루어지고 있다. 그러나 블루투스는 저전력 기술 중 높은 전력을 소모하기 때문에 조명기기가 증가할수록 전력사용량이 증가하기 때문에 저전력을 유지하기 어렵다는 문제점이 있다. 따라서 본 논문에서는 Zigbee 기술을 기반으로 조명기기를 제어할 수 있는 시스템을 설계하였다.

In this paper, we propose and implement the automated brightness control system using distance measuring sensor for reducing the power consumption of emotional lighting device. In order to reduce the power consumption of emotional lighting devices which express continuous color changes, the proposed device measures the distance continuously using ultrasonic sensor and by using this, it also performs PWM Dimming control. The lighting device is composed of micro controller, LED driver, ultrasonic sensor, communication module and so on. And the device performs the real time brightness control by adapting the measured distance information from ultrasonic sensor to PWM signals. From this experiment, we implement the active lighting system which minimizes unnecessary power consumption during user's absence by adapting existing energy reducing techniques.

LED illumination has been developed from simple illumination to human oriented multi-functional system depending on the IT convergence trends. Thus, the convergence of IT technology such as various types of sensor and communication functions with application software can make saving of energy, and there are also several needs about the tailor-made illuminations requirements for the diverse users who want to take their own colors, strengths of the light. For the adaption of these kinds of intelligent system illumination, user oriented sensor and control should be possible. The LED lighting control system transmits and receives data via the Bluetooth mesh network and provides functions such as LED lighting control, LED lighting condition monitoring, energy usage monitoring, and energy peak point management. Therefore, in this paper, we suggest wireless communication platform and control system for the LED illumination control. We can expect life extension of LED illumination, and energy saving through this suggested system.
