6. The device according to claim 1 , wherein the touchpad comprises a plurality of touch sensitive pads, said touch sensitive pads being arranged for association with different ones of the data lines between successive LED light sources in said array.

7. The device according to claim 1 , wherein the touchpad comprises a sliding surface for touch-sensing arranged for associating a touched location on the sliding surface with a position in the array of individually controllable LED light sources of the particular LED light source.

8. The device according to claim 1 , wherein the device further comprises a timer arranged for recording a time value of the duration of touching the touchpad; and

wherein the controller is arranged for providing a control signal for controlling the load based on said time value.

9. The device according to claim 1 ,

wherein the particular LED light source in the array of the individually controllable LED light sources comprises a lighting property;

wherein the controller is arranged for retrieving the lighting property based on the position of the particular LED light source, and for providing a control signal for controlling the load based on said lighting property; and

wherein the lighting property comprises at least one of: a light color, a light color temperature, a light modulation, a beam width, and a light intensity.

10. A system of controlling a load with a touch user interface, the system comprising the device according to claim 1 and a load, wherein the load comprises an electronic device.

11. A method of controlling a load with a touch user interface, the method comprising:

sending control data over data lines to a particular LED light source in an array of individually controllable LED light sources, wherein said data lines are arranged for interconnecting successive LED light sources to obtain a daisy-chain of successive LED light sources in said array;

removing, with the particular LED light source, one or more bits from the control data and providing, over the data lines, resulting control data downstream in the daisy-chain;

connecting, with a touchpad when in use touched, one of the data lines with a feedback line;

receiving the resulting control data over the feedback line when the touchpad is touched;

comparing said sent control data with said received resulting control data for associating the touchpad, when in use touched, with a position in the array of individually controllable LED light sources of the particular LED light source;

providing a control signal for controlling, with said controller, the load based on said position; and

storing, in a memory, a history of touching the touchpad; and wherein the providing a control signal for controlling the load is based on said history.

12. The method of controlling a load with a touch user interface according to claim 11 , and comprising: recording a time value of the duration of touching the touchpad; and wherein the providing a control signal for controlling the load is based on said time value.

13. A computer program product for a computing device, the computer program product comprising computer program code to perform the method of claim 11 , when the computer program product is run on a processing unit of the computing device.

14. A system of controlling a load with a touch user interface, the system comprising:

a device with a touch user interface for controlling a load, the device comprising:

an array of individually controllable LED light sources;

data lines for interconnecting successive LED light sources to obtain a daisy-chain of the successive LED light sources in said array and for rippling control data through the daisy-chain to a particular LED light source in said array, wherein the particular LED light source in said array is arranged for removing one or more bits from the control data and for providing resulting control data downstream in the daisy-chain;
