Patent ID: 8339274

Claim:
A system for automatically adjusting a lighting atmosphere based on presence detection, the system comprising at least one sensor for gathering information associated with a presence level of people in a supervised area, said gathered information including the number of people in the supervised area and the number of people passing through the supervised area, and a processing unit for determining the presence level of people in the supervised area based on the gathered information and for adjusting the lighting atmosphere based on the determined presence level by controlling the dynamics level and interactivity level of the lighting atmosphere depending on the determined presence level, wherein the processing unit is configured: to compare the determined presence level with a threshold and to adjust the lighting atmosphere, if the determined presence level is above the threshold, and to control said dynamics level and said interactivity level of the lighting atmosphere such that one or more dynamic effects of the lighting atmosphere are either disabled or visibly altered, if the determined presence level is above the threshold.
