Abstract

A distributed lighting system of multiple intelligent luminaires is considered for providing daylight and occupancy adaptive illumination. Each intelligent luminaire has a light sensor and an occupancy sensor that provides information on local light level and presence, respectively, and has a controller that adapts dimming level of the light source and a communication module. The illumination objective is to provide a desired average illuminance value over occupied/unoccupied zones at the workspace, specified in turn by occupancy-based set-points at corresponding light sensors. Two classes of proportional-integral (PI) controllers are considered to adapt the dimming levels of the luminaires to varying daylight levels under two networking scenarios. In one scenario, each controller operates stand-alone, sharing no information across other controllers, and has information about global occupancy. In the second scenario, controllers exchange control information within a neighborhood. The performance of the considered controllers is evaluated using photometric data from a DIALux implementation of an example open-plan office under different daylight and occupancy scenarios.
