Abstract
The invention relates to a lighting system for lighting a space (R) which lighting system has means () for producing space illumination over a large area, and means () for producing concentrated local lighting. Furthermore the lighting system has a presence detector () for detecting the presence of at least one person (P) in the space (R) and a control device () for controlling the means () for producing the space illumination and the means () for producing the local lighting. To this end the control device () is configured to control the space illumination over a large area automatically as a function of the daylight or as a function of the daytime and to control the local lighting automatically as a function of the presence of at least one person (P) in the space (R). Because the space illumination is controlled automatically as a function of the daylight or of the daytime, the illumination can be prevented from being reduced so much that a lighting mood is produced which has a negative effect. Nevertheless the lighting system can be controlled advantageously n energy terms, in particular since the local lighting can be controlled as a function of the presence of persons in the space.
