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.
