Everything has been simplified and abbreviated. The stream of times can be found through the smart phones since the ubiquitous world has be mentioned by Mark Webber. Judging by the flow of times, it's easy to predict that it will be more developed in the future. There are several ways of the development and one of them is to click a button in everything. For this study, the MaKey of MIT MELIALAB shows the possibility. As applying the study of clicking a button in everything, this paper proposes the Smart Lighting Control System using the u-Button. For the actual implementation, u-Button Module with MICAz and various sensors, Actuator Node composed of ZigBeX and LED Module are produced.

Lighting systems in modern society has been developed using a combination of IT technology and LED lighting for the purpose of bringing about changes in human-centered natural lighting and to take advantage of the efficient management and energy saving of LED lighting. In this paper, we propose an LED lighting control system that can control the color temperature and brightness of LED lighting composed of 3000K Warm LEDs and 6000K Cool LEDs by using an Arduino Due and wireless communication technology such as Bluetooth and Zigbee. The Arduino Due allows the color temperature of the lighting to be adjusted in several steps by controlling the duty rate and enables many lights to be controlled using Zigbee communication capable of 1: N multiple communication. By using Bluetooth communication, it is possible to easily control the LED lighting by means of a smartphone application, thereby enhancing the convenience for the user. The wireless communication based LED lighting control system implemented in this study cannot only provide human-centered lighting through its color temperature control from 3067K to 5960K and illumination control, but can also reduce the power consumption and be used as a natural-friendly lighting system.

Nowadays, the limitation of Lighting control and management skills is the excessive cost of equipments, the operational difficulties and wasting energy. To solve this problem is in need of communication and management S/W that is worked out complexly well as a information system of smart lighting energy, which is loaded wireless network facility. This paper made a study od the energy saving technology through energy monitoring and we developed LEIS(Lighting Energy Information Sysem) to converge this one. LEIS is monitoring and control lighting energy data that is collelcted from sensors by Zigbee mesh network and shows lighting use information by visualization to users. It is consists of lighting energy information data base based on LEM(Lighting Energy Metering) information and LEIS Web application, provide function scenario to manage energy optimization through LEIS.

This study analyzed that technological competition, variety and simility of Green IT fields using patents data. To achieve this, we limited range of Green IT that reduction of energy, eco-friendly technology. Therefore we conducted analysis of patents that power saving systems, light control system, smart system, cloud computing and green house/eco systems. As the result of that, power saving field was the most developed. The simililarty of power saving and cloud computing systems are very high and similiarities of light control system, green house/eco systems and smart system were very high.

When lighting has installed indoor, we control lighting using human-detecting sensors for people who pass at night and places that are lack of quantity of light. However, malfunction can be caused by positions of inappropriate sensors, and in the case of passages of big buildings, it is a problem that even after a person pass, light apparatuses are turned on for a long time. In this paper, we propose lighting control system based on location positioning for energy saving that control lighting in accordance with passers's position through indoor location positioning. This system use the fingerprinting technology that is one of the location positioning technologies and RSSI data that is collected by a smart device. Using those, it can turn on only lightings that are included in the positioned location and reduce unnecessary power consumption. As a result of experiment, on condition that four people were existing and illumination was 308 lux, we assured reduction effect of 49 Wh.

In this paper, we implemented total monitoring system in which LED light turned on only when user detected and LED light turned out only when user disappeared. This system is composed of two modules, one is HW board based on Micro Controller and the other is SW control system based on Web server. Micro controller board is based on ATMega2560 chip which is connected with Infra Red and Ultra sonic sensors. Web based monitoring system was designed can be used in smart device. The validity of this monitoring system was proved by integration test of two modules.

최근에는 LED 조명으로 인해 조명 제어의 유연성이 높아짐에 따라 가정이나 사무공간에서 해당 공간의 목표 조도를 설정하고 현재 내부조도의 상황에 따라 자동으로 조명을 디밍하는 형태로 연구가 이루어지고 있다. 그러나 이러한 제어방식이 현재 주택용 요금제도로 운영 중인 고정요금제에서는 에너지 비용을 감소시키나, 스마트그리드에서 운영될 RTP(Real Time Pricing)에서는 요금 단계에 따라 오히려 에너지 비용이 증가될 수 있다. 이에 본 논문은 실시간 요금 단계에 따라 LED 조명의 목표 조도를 가변적으로 변화시켜 조명 에너지 비용을 최소화하고 사용자의 작업에 적합한 상황별 조도를 자동으로 제어하여 작업자에게 편리함을 제공하고자 한다. 이때 요금 단계에 따른 상황별 최저 및 최고 조도기준은 KSA 3011 및 IES를 참조하며, 최소한의 조명 에너지 사용을 위해 외부 광량을 최대한 활용하여 현재의 시간에 따라 블라인드의 Open/Close를 자동으로 서비스한다. 사용자의 상황은 PIR, Electric Powermeter, Piezoelectric 센서로부터 사용자의 위치, 가전기기 사용 유무, 착석 여부 등을 파악하고, RTP 요금에 따라 하루동안의 조명에 사용된 전력요금을 시뮬레이션한다.
