Abstract

A lighting system and method for providing a particular lighting pattern from a predetermined set of lighting patterns are disclosed. The system comprises a presence detector for detecting a presence of a person in an area, a timer for measuring a duration of the presence, a pattern selector for selecting the particular lighting pattern from the predetermined set of lighting patterns based on the presence and the duration, and a plurality of adjustable light sources for applying the particular lighting pattern.

Claims

1. A lighting system for providing a particular dynamic lighting pattern from a predetermined set of dynamic lighting patterns, the system comprising:

a presence detector for detecting a presence of a plurality of persons at a location;

a timer for measuring a duration of the presence of each individual of said plurality of said persons;

a pattern selector for selecting the particular dynamic lighting pattern from the predetermined set of dynamic lighting patterns based on the presence and on the duration of each of said plurality of persons, wherein the particular dynamic lighting pattern comprises a series of light effects;

a plurality of adjustable light sources for applying the particular dynamic lighting pattern to the location during the presence of each of said persons;

wherein said pattern selector includes a plurality of rules reactive to measurement of social patterns and presence patterns over time as determined by said timer, said rules operable on said adjustable light sources based upon the number of said plurality of persons and the temporal character of each of said plurality of persons activities.

2. A lighting system according to claim 1, wherein said presence detector is arranged for detecting said plurality of persons being present, the timer is arranged for measuring a duration of the number of persons being present, and the pattern selector is arranged for selecting the particular dynamic lighting pattern further based on said social patterns and presence patterns.

3. A lighting system according to claim 1, further comprising an orientation detector for measuring an orientation of each of said persons and wherein the pattern selector is arranged for selecting the particular dynamic lighting pattern further based on said orientation.

4. A lighting system according to claim 1, wherein the timer is arranged for further measuring an actual time wherein the pattern selector is arranged for selecting the particular dynamic lighting pattern further based on the actual time.

5. A lighting system according to claim 1, further comprising an input for receiving a further dynamic lighting pattern and means for including the further dynamic lighting pattern in the set of dynamic lighting patterns.

6. A lighting system according to claim 1, wherein the particular dynamic lighting pattern defines a brightness, and/or color temperature, and/or directivity of light.
