A controller (110) for a lighting system (100) is provided. The controller is connectable to a plurality of light sources (120, 122) of different colors and/or different color temperatures, and to a user control element (130) configured to generate a user selected value from a range of user selectable values. The controller is configured to receive a change of the user selected value, and as a response to and corresponding to this change adjust a combined output of the plurality of light sources to produce a change in output color, color temperature and/or luminous flux of a combined light of the plurality of light sources. The change is such that, as function of the user selected value in separate first intervals of the user selectable values, the output color and/or color temperature is kept approximately constant while the luminous flux obtains a local minimum or local maximum in each first interval. Similarly, in at least one second interval in between the first intervals, the output color at least changes from a first color to a second color and/or the color temperature increases or decreases while the luminous flux is kept approximately constant. A lighting system including the controller, and a method of operating a lighting system having such a controller are also provided.
A controller for a lighting system, connectable to a plurality of light sources of different colors and/or different color temperatures, and connectable to a single user control element configured to generate a user selected value from a range of user selectable values, said user selectable values separated in alternately arranged first intervals and second intervals of the user selectable values, wherein the controller is configured to:
A lighting system including a plurality of light sources of different colors and/or different color temperatures, a user control element configured to generate a user selected value from a range of user selectable values, and the controller of any one of the preceding claims connected to said plurality of light sources and to the user control element.
A method of operating a lighting system including a plurality of light sources of different colors and/or different color temperatures, said method comprising:
