Devices (1) comprise receivers (11) for receiving signals (4) coming from signal-systems (5) at objects (3) and comprise converters (12) for converting the signals (4) into control information (7, 8) for controlling light-systems (2) for illuminating the objects (3). The signal-system (5) may comprise a sensor (51, 52) for sensing light (41-44) and for providing sensing information and a transmitter (53) for transmitting the signal (4) comprising the sensing information to the device (1). Alternatively the signal-system (5) may comprise a reflector (54) for converting light (41-44) into reflected light or may comprise a light source (55) for providing light (56), whereby the receiver (11) comprises a sensor (19) for sensing the reflected light or the light (56) and for providing the sensing information (7, 8). The device (1) may comprise an analyzer (14) for analyzing the sensing information (7, 8) and a memory (15) for storing location information and/or light information and/or signal-system information and a generator (16) for generating search information for letting the light-system (2) search for the signal-system (5).
