Abstract

A lighting system is provided for providing a particular lighting pattern from a predetermined set of lighting patterns. 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 lighting means for applying the particular lighting pattern.

Claims

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

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 lighting means for applying the particular lighting pattern.

2. A lighting system according to claim 1, wherein the lighting means are operative to apply the particular lighting pattern to the area.

3. A lighting system according to claim 1, wherein

the presence detector is arranged for detecting a number of persons being present, the number being larger than one,

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 lighting pattern further based on the duration of the number of persons being present.

4. A lighting system according to claim 3, wherein the number is two.

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

6. 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 lighting pattern further based on the actual time.

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

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

9. A method for providing a particular lighting pattern from a predetermined set of lighting patterns, the method comprising the steps of:

monitoring a presence of a person in an area,

monitoring a duration of the presence,

selecting the particular lighting pattern from the predetermined set of lighting patterns based on the presence and the duration, and

applying the particular lighting pattern.

10. A method according to claim 9, wherein the particular lighting pattern is applied to the area.

11. A computer program product, which program is operative to cause a processor to perform a method as claimed in claim 9.
