Abstract

A lighting system comprises one or more illuminants and a control device for adjusting light parameters of the illuminants during operation. The control device is arranged to adjust the light parameters time-dependently according to a predetermined course of the light parameters. The control device is further adapted to receive a one-dimensional user setting and to change the course of the light parameters according to the one-dimensional user setting.

First claim

What is claimed is:

1. A lighting system comprising:
at least one illuminant configured to emit light characterized by light parameters; and
a control device configured for use in entering a desired deviation from a predefined course of the light parameters, wherein:
the control device is configured to output a one-dimensional quantity which affects deviation from an initial setting of the light parameters on the basis of at least one stored function that describes the light parameters; and
setting of the control device does not have a direct effect on the light parameters but does have a direct effect on the at least one stored function that describes the light parameters;
wherein a degree of deviation from the initial setting is defined by a function which depends on a difference between the initial setting and at least one of:
a maximum value of at least one of the light parameters; and
a minimum value of at least one of the light parameters.

2. The lighting system of claim 1 , wherein the one-dimensional quantity represents a number of units of change toward either a higher value or a lower value of at least one of the light parameters.

3. The lighting system of claim 1 , wherein the light parameters comprise at least one of intensity, color temperature, beam direction, and beam angle.

4. The lighting system of claim 1 , wherein the initial setting is defined by a function which depends on at least one of a time of day and a time of season.

5. The lighting system of claim 1 , wherein the function which defines the degree of deviation from the initial setting further depends on the setting of the control device.

6. The lighting system of claim 5 , wherein the setting of the control device corresponds to a change in a pre-defined control curve for the light parameters.

7. The lighting system of claim 5 , wherein identical changes to the setting of the control device have different effects on the light parameters at different times of day.

8. The lighting system of claim 5 , wherein the setting of the control device corresponds to at least one of:
a value entered or calculated based on a gesture; and
a value entered or calculated based on an output of a sensor communicatively coupled with the lighting system.

9. The lighting system of claim 5 , wherein the setting of the control device is generated automatically based on at least one of:
a sensor communicatively coupled with the lighting system; and
a calculation from user data.

10. The lighting system of claim 1 , wherein the function which defines the degree of deviation from the initial setting further depends on at least one of a time of day and a time of season.

11. The lighting system of claim 1 , wherein the function which defines the degree of deviation from the initial setting further depends on at least one further variable.

12. The lighting system of claim 1 , wherein the control device is configured to output only the one-dimensional quantity.

13. The lighting system of claim 1 , wherein the control device comprises at least one of:
a physical control element manipulatable by a user; and
a virtual control element presented on a user interface and manipulatable by the user.

14. The lighting system of claim 1 , wherein the control device is a mobile device comprising at least one of a smartphone and a tablet computer.

15. The lighting system of claim 1 , further comprising at least one of:
a mobile device configured to communicate with some other portion of the lighting system; and
a sensor configured to communicate with some other portion of the lighting system.

16. A lighting system comprising:
at least one illuminant configured to emit light characterized by light parameters; and
a control device configured for use in entering a desired deviation from a predefined course of the light parameters, wherein:
the control device is configured to output a one-dimensional quantity which affects deviation from an initial setting of the light parameters on the basis of at least one stored function that describes the light parameters;
setting of the control device does not have a direct effect on the light parameters but does have a direct effect on the at least one stored function that describes the light parameters; and
a degree of deviation in the light parameters is defined by a difference between the initial setting of the light parameters and at least one of a maximum value and a minimum value of at least one of the light parameters.

17. The lighting system of claim 16 , wherein the degree of deviation in the light parameters is further defined by at least one of:
the setting of the control device; and
at least one of a time of day and a time of season.

18. The lighting system of claim 16 , wherein the degree of deviation in the light parameters is further defined by each of:
the setting of the control device; and
at least one of a time of day and a time of season.

19. The lighting system of claim 16 , wherein the control device is a mobile device comprising at least one of a smartphone and a tablet computer.

20. The lighting system of claim 16 , further comprising at least one of:
a mobile device configured to communicate with some other portion of the lighting system; and
a sensor configured to communicate with some other portion of the lighting system.
