using by Modeling of Lighting Environment by Kalman Filter Fumiya KAKU , Mitsunori MIKI , Tomoyuki HIROYASU and Masato YOSHIMI (Received October 6, 2010) We propose the fault detection method in Intelligent Lighting System. Modeling of Lighting Environment is used for detection. It shows relation between lighting fixture and illuminance sensor. It is calucated based on log data of Intelligent L...

Highway lighting consumes considerable amounts of energy, yet smart lighting techniques provide significant potential for reducing this consumption. This paper introduces a preliminary algorithm, simulation studies and a small-scale hardware prototype for a smart highway lighting management system based on road occupancy. Wireless Sensor Network (WSN) detects the presence of vehicles along the ...

As issues of environment and energy draw keen interest around the globe due to such problems as global warming and the energy crisis, LED with high optical efficiency is brought to the fore as the next generation lighting. In addition, as the national income level gets higher and life expectancy is extended, interest in the enhancement of life quality is increasing. Accordingly, the trend of li...

We focus on office lighting environment and conduct a study of Intelligent Lighting System that provides light brightness in accordance to an individual office workers’ needs. For purpose of commercialization of this system, Intelligent Lighting System using in-office frame was introduced at Kokuyo Co., Ltd. This place is a special work area used for meetings and discussions, etc. Intelligent L...
