Lighting system and method for controlling a lighting system
First Claim
1. Lighting system, comprising:
- a plurality of ambient light sources for providing an ambient lighting,a plurality of task light sources, each task light source being provided to illuminate a predetermined area with variable intensity, anda plurality of occupancy sensors for detecting occupancy in a number of occupancy zones and for controlling said ambient light sources and task light sources, each occupancy sensor being provided to communicate wirelessly with other occupancy sensors,wherein on the detection of occupancy of at least one zone, the occupancy sensors detecting the occupancy activate at least one ambient light source and send a control signal to other occupancy sensors to activate other ambient light sources, and the intensity of a group of task light sources illuminating the occupied zone is set to a level higher than the intensity of the remaining task light sources.

Abstract
The present invention refers to a lighting system comprising ambient light sources and task light sources, and occupancy sensors for detecting occupancy in a number of occupancy zones and for controlling the ambient light sources and task light sources. Each occupancy sensor is provided to communicate wirelessly with other occupancy sensors. On the detection of occupancy of at least one zone, the occupancy sensors detecting the occupancy active at least one ambient light source and send a control signal to other occupancy sensors to active other ambient light sources, and the intensity of a group of task light sources illuminating the occupied zone is set to a level higher than the intensity of the remaining task light sources. The invention also refers to a respective method for controlling a lighting system of this kind.
