An intelligent lighting system for exhibition applications

This paper presents the design and the implementation of a lighting system which is able to detect the approach of the visitors and then turn the lighting onto the normal intensity to let the exhibition be bright enough. All lightings are equipped with the energy-saving function which will turn itself to the dimming level automatically after the visitors' leaving. PIR (Passive Infrared) sensors are utilized in the system instead of a video camera for the purposes of both cost-down and privacy issue. The lightings are also designed to have network interface to let them be able to be connected together to form an intelligent lighting system which can not only collect the exhibition information but also help the administrators to secure the exposition.
