Abstract: The invention relates to control system configured for controlling at least one controllable device. The device has been assigned a corresponding identifier and is configured for transmitting an identification signal comprising the identifier of the device. The control system comprises a display for displaying a control item configured for controlling the controllable device. The control system also comprises a receiver configured for wirelessly receiving the identification signal comprising the identifier. The control system is configured for assigning a position of the control item on the display to the device identified by means of said received identifier.

Abstract: A method for driving a lamp (2) comprises the steps of: generating a lamp current (ICONST) having a constant magnitude; defining a commutation period having a duration TCOMM; defining a time base of original commutation moments, having fixed mutual intervals of 0.5*TCOMM; receiving data to be embedded in the light output; commutating the lamp current at commutation moments; wherein individual commutations are time-modulated in order to encode said received data. Preferably, a commutation moment is: either equal to an original commutation moment if there are no data to embed; or advanced over a modulation distance (?) with respect to the corresponding original commutation moment in order to encode data having a first value (“0”); or delayed over said modulation distance (?) with respect to the corresponding original commutation moment in order to encode data having a second value (“1”).

Abstract: This invention relates to a method for processing light in a structure, such as a room or a part thereof, a vehicle, etc., where several light sources are arranged in the structure. The light sources emit light carrying individual codes. A camera is arranged in a camera position of the structure and registers images of spots of the light. The spots can be, “for instance, illuminated areas of a floor or the direct light images of the light sources. The individual codes are derived from the registered images and one or more properties, such as for instance light source position or light intensity, related to the associated light source, is determined. The method is performed by means of a lighting system having several light sources, a camera, and a signal processing apparatus. Typical applications for the invention are light source commissioning and real time foot-print measurements.

Abstract: It is presented a method for transmitting lighting device data. The method comprises the steps of obtaining, in a lighting device, a subset of lighting device data, the lighting device data containg information of the lighting device, transmitting, from the lighting device, using light, the subset of lighting device data, and repeating the above steps until all subsets jointly corresponding to the complete lighting device data have been transmitted. A corresponding lighting device and lighting system are also presented.
