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

The invention claimed is:

1. A lighting system comprising:
one or more illuminants; and
a control device for adapting light parameters of the illuminants during operation, wherein the control device is arranged to adapt the light parameters time-dependently based on a current time of day according to one or more predetermined courses of the light parameters, characterized in that the control device is further arranged to receive a one-dimensional user setting and to change the courses of the light parameters according to the one-dimensional user setting;
wherein the one or more predetermined courses of the light parameters comprise:
at least two fixed value points defined in terms of time of day and one-dimensional user setting; and
at least one interpolated value point lying between the at least two fixed value points in terms of at least one of time of day and one-dimensional user setting.

2. The lighting system according to claim 1 , wherein the light parameters comprise at least one of intensity, color temperature, beam direction, and beam angle of the light emitted by the one or more illuminants during operation.

3. The lighting system according to claim 1 , further comprising an input connected to the control device for inputting the one-dimensional user setting.

4. The lighting system according to claim 3 , wherein the input is a direct input comprising a switch, push button, rotary or slide control, or an application running on a computer.

5. The lighting system according to claim 3 , wherein the input comprises a display, wherein the input is arranged to display on the display a measure of the change in the course of the light parameters.

6. The lighting system according to claim 1 , wherein the control device is further arranged to change the predetermined courses of the light parameters according to further input values.

7. The lighting system according to claim 6 , wherein the control device is further arranged to at least one of determine the further input values and receive the further input values from one or more external sensor.

8. The lighting system according to claim 1 , wherein the control device is further adapted to change the predetermined courses of the light parameters non-linearly with the one-dimensional user setting.

9. The lighting system according to claim 1 , wherein the control device is further adapted to take into account at least one of maximum values and minimum values for the light parameters when changing the courses of the light parameters.

10. The lighting system according to claim 9 , wherein at least one of the maximum values and the minimum values depends on at least one of temporal parameters and parameters other than temporal parameters.

11. The lighting system according to claim 1 , wherein the control device is further adapted to reset the changed courses of the light parameters to the predetermined courses of the light parameters after a predetermined first period of time.

12. The lighting system according to claim 11 , wherein the control device is further adapted to reset the changed course of the light parameters to the predetermined course of the light parameters over a predetermined second period of time.

13. The lighting system according to claim 1 , wherein the control device is further adapted to maintain the changed progressions of the light parameters also after switching the one or more illuminants off and on again if there is at most a predetermined third time period between switching off and on again.
