Wireless Sensor Network-based Illumination Control.

In this paper the problem of illumination control in a lighting system with networked lighting devices is examined. The luminaries have fluorescent light sources dimmable by a local controller. The optimal dimming values are calculated according to the user and legal requirements for illuminance of different workspaces and their actual illumination levels are measured by light sensors. A closedloop lighting device control algorithm is used for obtaining the set illumination values. So a distributed and energy optimised illumination control with the use of daylight can be effectively implemented. The proposed approach is evaluated in lecture rooms and office environments.
