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. ## Claims ### Claim 1 A lighting system comprising: at least one light fixture having at least one light parameter; and a control device configured to control the at least one light parameter according to: a first function which provides time-dependent control of the at least one light parameter based on a plurality of defined support points which, at defined times (t), predetermine associated values for the at least one light parameter; and a second function which is overlaid on the first function and which provides control of the at least one light parameter based on an external signal, wherein the plurality of support points are changed for each time (t) according to the second function overlaid thereon. ### Claim 2 (depends on 1) The lighting system according to claim 1, wherein the first function and the second function operate to change both an instantaneous value of the at least one light parameter statically and a profile of light dynamics of the lighting system for each time (t). ### Claim 3 (depends on 1) The lighting system according to claim 1, wherein the control device is further configured to reset the change to the plurality of support points after a predetermined first period. ### Claim 4 (depends on 3) The lighting system according to claim 3, wherein the reset varies with time over a predetermined second period. ### Claim 5 (depends on 1) The lighting system according to claim 1, wherein the control device is further configured to retain the change to the plurality of support points in a manner dependent on a predetermined period. ### Claim 6 (depends on 1) The lighting system according to claim 1, wherein: the at least one light parameter comprises illumination intensity; and the first function, expressed as SB,0(t) for illumination intensity, and the second function, expressed as fB(t,x) for illumination intensity, operate to provide a changed setting for the illumination intensity, expressed as SB(t,x), according to the following relationship: SB(t,x)=SB,0(t)·fB(t,x). ### Claim 7 (depends on 1) The lighting system according to claim 1, wherein: the at least one light parameter comprises color temperature; and the first function, expressed as ST,0(t) for color temperature, and the second function, expressed as fT(t,x) for color temperature, operate to provide a changed setting for the color temperature, expressed as ST(t,x), according to the following relationship: ST(t,x)=ST,0(t)·fT(t,x). ### Claim 8 (depends on 1) The lighting system according to claim 1, wherein the at least one light parameter is selected from the group consisting of: illumination intensity; color temperature; transmission direction; and transmission angle. ### Claim 9 (depends on 1) The lighting system according to claim 1, wherein the at least one light parameter comprises both illumination intensity and color temperature. ### Claim 10 (depends on 1) The lighting system according to claim 1, wherein the external signal is from a user interface. ### Claim 11 (depends on 10) The lighting system according to claim 10, wherein the external signal includes an input value indicative of at least one of a time of day and a date. ### Claim 12 (depends on 10) The lighting system according to claim 10, wherein the external signal includes an input value that lies between a lower limit value and an upper limit value. ### Claim 13 (depends on 12) The lighting system according to claim 12, wherein at least one of the lower limit value and the upper limit value is a function of time (t). ### Claim 14 (depends on 1) The lighting system according to claim 1, wherein the external signal is from a sensor. ### Claim 15 (depends on 14) The lighting system according to claim 14, wherein the external signal includes an input value indicative of a detected presence of an occupant within a region illuminated by the at least one light fixture. ### Claim 16 (depends on 14) The lighting system according to claim 14, wherein the sensor is external to the at least one light fixture. ### Claim 17 (depends on 1) The lighting system according to claim 1, wherein the defined times (t) correspond with a time of day or a time of season.
