Abstract
The invention provides an improved 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 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 (i.e. e.g. to a successive LED light source) in the daisy-chain; a feedback line for feeding back the resulting control data; a touchpad for connecting, when in use touched, one of the data lines and the feedback line; a controller comprising (i) an output for sending the control data over said data lines to the particular LED light source, and (ii) an input for receiving the resulting control data over the feedback line when the touchpad is touched; and the controller being arranged for (i) 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, and (ii) providing a control signal for controlling the load based on said position.
