Abstract

A lighting system has at least one light fixture and a control device. The at least one light fixture has light parameters. The control device is in communication with the at least one light fixture. The control device has a plurality of one-dimensional user setting, a predetermined sequence of light parameters as a function of time, and an adjustment to the predetermined sequence as a function of a selected one-dimensional user setting.

First claim

The invention claimed is:

1. A lighting system comprising:
at least one light fixture having light parameters; and
a control device configured to:
adapt the light parameters according to a predetermined sequence of the light parameters as a function of time; and
change the predetermined sequence of the light parameters from the predetermined sequence to a changed sequence as a function of a one-dimensional user setting received from a first source external to and upstream of the control device;
wherein the one-dimensional user setting has a value that lies between a lower limit value and an upper limit value and determines how much the changed sequence deviates from the predetermined sequence; and
wherein in response to the one-dimensional user setting, the control device does not directly change current values of the light parameters, but rather, according to preset specifications, the control device changes a sequence of the light parameters from the predetermined sequence to the changed sequence, which affects the sequence thereof in the future.

2. The lighting system according to claim 1 , wherein the light parameters are selected from the group consisting of:
intensity of light emitted by the at least one light fixture in operation thereof;
color temperature of light emitted by the at least one light fixture in operation thereof;
transmission direction of light emitted by the at least one light fixture in operation thereof;
transmission angle of light emitted by the at least one light fixture in operation thereof; and
a mixture of any of intensity, color temperature, transmission direction, and transmission angle.

3. The lighting system according to claim 1 , further comprising an input device configured to serve as the first source.

4. The lighting system according to claim 3 , wherein the input device is configured as a direct input device selected from the group consisting of a switch, a knob, a slider, and an application.

5. The lighting system according to claim 3 , wherein the input device includes a display device configured to provide a displayed measure of the change to the predetermined sequence of the light parameters as a function of the one-dimensional user setting.

6. The lighting system according to claim 5 , wherein the display device includes a touch-sensitive display portion.

7. The lighting system according to claim 1 , wherein the control device is further configured to:
make an input value adjustment to the predetermined sequence of the light parameters as a function of an input value received by the control device from a second source external to and upstream of the control device.

8. The lighting system according to claim 7 , further comprising an input value sensor configured to serve as the second source.

9. The lighting system according to claim 7 , wherein the second source is an input sensor external to and upstream of the control device.

10. The lighting system according to claim 7 , wherein the input value is indicative of at least one of the date and the time of day.

11. The lighting system according to claim 7 , wherein the input value is indicative of a detected presence of an occupant within a region illuminated by the at least one light fixture.

12. The lighting system according to claim 1 , wherein the control device is configured to change the predetermined sequence of the light parameters from the predetermined sequence to the changed sequence as a function of the one-dimensional user setting in a non-linear manner.

13. The lighting system according to claim 1 , wherein at least one of the upper limit value and the lower limit value is a function of time.

14. The lighting system according to claim 1 , wherein the control device is further configured to:
reset the change to the predetermined sequence of the light parameters as a function of the one-dimensional user setting, wherein the reset occurs after a predetermined first time period.

15. The lighting system according to claim 14 , wherein the reset varies with time over a predetermined second time period.

16. The lighting system according to claim 1 , wherein the control device is further configured to:
retain the change to the predetermined sequence of the light parameters as a function of the one-dimensional user setting, wherein the retention is dependent on a predetermined time period.

17. The lighting system according to claim 1 , wherein changes to the current values of the light parameters are functionally derived from changes to the one- dimensional user setting.

18. A method of controlling a lighting system comprising at least one light fixture having light parameters, the method comprising:
using a predetermined sequence of light parameters stored on a control device to set the light parameters as a function of time; and
changing the predetermined sequence of the light parameters from the predetermined sequence to a changed sequence as a function of a one-dimensional user setting received from a first source external to and upstream of the control device;
wherein the one-dimensional user setting has a value that lies between a lower limit value and an upper limit value and determines how much the changed sequence deviates from the predetermined sequence; and
wherein in response to the one-dimensional user setting, the control device does not directly change current values of the light parameters, but rather, according to preset specifications, the control device changes a sequence of the light parameters from the predetermined sequence to the changed sequence, which affects the sequence thereof in the future.

19. The method according to claim 18 , further comprising:
making an input value adjustment to the predetermined sequence of the light parameters as a function of an input value received by the control device from a second source external to and upstream of the control device.

20. The method according to claim 18 , wherein changes to the current values of the light parameters are functionally derived from changes to the one- dimensional user setting.
