In this paper, A web-based server system was developed based on PDA(Personal Digital Assistants) for controlling and managing light facilities on-line with wireless communication efficiently. The control box of current light facilities may be implemented based on simple operational function. The operational quality of the light facilities will be efficiently improved with some practical advantages such as reduction of required facility, manpower and time in managing the lights and control boxes by using the popular PDA.

This paper proposes a novel design of enhanced auto light control system using PLC(Power Line Communication) and SMS(Short Message Service) to copy with emergent cases effectively. In the proposed system, the indoor sensing system is designed to send emergent messages to the users or system manager in case of fire or invasion, which may prevent secondary accident. In addition, data transmission using PLC may drastically decreases the number of lines. The experimental results show the effectiveness of the proposed system.

This paper describes th on-line maintenance system with integrated graphic environment for building electrical equipments. This system is based on the pre-defined troubleshoot knowledgebase with maintenance information. And this system utilizes the database and knowledgebase for the diagnosis of facility and runs on the operator's requirement and response. The operator is possible of a detailed observation, an early detection of abnormal state, a properly operation and a rapidly arrangement of electrical equipments. Especially, this system is developed using the maintenance of equipments, if needed, be operated by non-expertise.

Nowadays, Advanced country have devised a plan energy-saving through lighting effectiveness and increasing performance of lighting control system. If it uses the LED as a source of light then conserve electricity by 50%. This paper implement LEMS(Lighting Energy Management System) that applicate and Smart Dimmer and Smart Switch that control the digital LED light, support wired-wireless communication using USN(Ubiquitous Sensor Network). This system of validity and reliability control special purpose lamp including indoor and outdoor lighting and landscape lighting effectively. It minimize the use of indoor and outdoor lighting energy by USN remote integral control function of Digital System Lighting of LED and increase effectiveness of energy and is a collaborative system that can feedback the use of electricity by measurement itself through Web and Switch.
