We propose a lighting system which adjusts lighting colors. The lighting system adjusting colors is a system that provides required illuminance and lighting color at an appropriate location. This system consists of many intelligent lighting with RGB fluorescent lamps, many chroma sensors and an electric power meter. These equipments are connected to a network. The chroma sensor can measure the ...

The intent of this paper is to initiate a discussion within the community interested in commercial refrigerators, on the possible use of LED lighting in commercial refrigerated and freezer display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. LED is a solid-state light source tha...

Buildings play an important role in the energy demand sector. Due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. Lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...

smart home is composed of several controllers with different plants in control. if each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. the function of different controller system may has conflict in some condition...

We are doing research and development of an intelligent lighting system. In the intelligent lighting system, the algorithm which controls lighting fixtures is important. In this research, we examine how to grasp the position relation between the lighting and the illuminance sensors with sufficient accuracy, and we propose a lighting control algorithm which estimates accurate position relation b...
