This paper proposes a novel design of auto light control system with high efficiency using RS-485 to save lighting energy in new and existing buildings. The proposed system consists of ALSU(Auto Light Sensor Unit) which is connected with RS-485 to control lighting appliances, ALS(Auto Light Unit), and Hi-FACS which is a monitoring system using communication interface. lighting appliances are automatically controlled by ALSU which detects moving objects. The total system is designed to be controlled by either manual or auto mode by using the ALS. In addition, the monitoring system receives the information on the state of the lighting appliances from ALSU and ALS to control the proposed system We compared the proposed system with the conventional one in functionality and energy saving point of view. Through some experimental results, the proposed system shows better performance in various circumstances.

This paper describes the smart illuminating system based on the obstacle environmental presetting to improve the user convenience to easy lighting and energy conservation. Obstacle environment has trouble controlling the illuminating equipment using manual buttons in certain circumstances, which requires a smart remote controller. The smart remote controller is operated by the smart phone, motion sensor and timer to turn on and off the lamps. The event sensor module transmits the signals of the event occurrence to equipment on the remote place when smart phone and motion sensor detect an event, and the illuminator received the event turn on or off the lamp. The system results in energy saving by simple on/off control and manipulating the operating time with controlling the illuminating system preset by user's obstacle or preference circumstances. The proposed system implementation is experimented to figure out the energy saving about13.5w/h and the optimized convenience control.

In this paper, we have designed and implemented lamp control system in underground parking place using WWW. The proposed system consists of lamp control system which is connected by RS-485 communication bus and monitoring system (WebPL) which can provide web interface using the web server. The lamp control system is controlled through a user command within the monitoring system (WebPL), senses moving object and turns lamps in underground parking place on or off. The monitoring system displays the status values of on or off received from lamp control system on the web browser and can real-timely control lamps in underground parking place on the web browser.

This paper is to show the designing for LED lights driver unit. The main purpose of driver designing is high electrical efficient performance and intelligent control LED driver. Nowadays, a lightning system with some of charactestics such as an environmentally friendly purposes with a possible reduction of electric power consumptions. We constitute a intelligent contron LED control system that helps to save an electric energy, and a communication system to control the system. This LED driver can be used for intelligent light control. This product expects to improve the light control by dimming instead of interlace on/off light control that increases the social cost such as car accidents and etc.

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.

기존의 조명제어는 주로 밝기의 제어를 목적으로 하였으나 최근에는 스마트폰을 이용하거나 스마트 홈 디바이스를 이용하는 등 다양한 방법으로 조도 및 색온도를 사용자가 직접 조작할 수 있는 형태로 발전하고 있다. 또한 사용자의 감성이나 능률에도 영향을 미칠 수 있는 조명 시스템에 대한 연구도 활발히 진행되고 있다. 그러나 기존의 조명 제어 서비스는 조명의 색과 밝기 제어가 가능하지만 현재의 조명 환경에 대한 적합 여부는 고려되지 않는 경우가 많았다. 본 논문에서는 스마트폰을 이용한 음성 인식 기반의 사용자 맞춤형 조명제어 시스템을 제안한다. 제안 시스템은 사용자가 제공받고 있는 조명의 특성을 스마트폰을 통해 계측하여 확인하고 스마트폰 어플리케이션 기반의 제어 또는 음성인식 기반의 제어를 통해 사용자 맞춤형 조명 서비스를 제공한다.
