A method for assigning light sensors for regulating a lighting system includes switching the lighting of the lighting system into a first switching state such that a first lighting group emits light with a predetermined luminous flux, switching the lighting of the lighting system into a second switching state such that the first lighting group emits light with a reduced luminous flux by comparison with the predetermined luminous flux or emits no light, and measuring a luminance of the light reflected by a reference surface respectively assigned to the light sensors with the aid of the light sensors to determine a first measurement value in the first switching state and a second measurement value in the second switching state. The method may further include assigning a sensor to the first lighting group based on a comparison of difference values formed for each of the light sensors, and storing the assignment.

In various embodiments, a circuit arrangement for operating light sources is provided. The circuit arrangement includes an input for inputting an input voltage, an output for outputting an output current, a first interface for controlling the circuit arrangement, and a second interface. The circuit arrangement is configured to set two different operating modes: in a first operating mode the circuit arrangement is configured to be controlled via the first interface and to receive information concerning the output current via the second interface and to correspondingly set the output current at the output, and in a second operating mode the circuit arrangement is configured to be controlled and to receive the information about the output current to be set at the output via the first interface, and to receive information from a sensor via the second interface and to process said information.

A light regulation device includes at least one light sensor which provides at its output a real brightness value, at least one regulator to which a set brightness value can be supplied, besides the real value, and a number n of output connections, n being greater than or equal to two. Each output connection is coupled to the output of a regulator in order to modify the light flux which can be supplied to at least one of the lighting elements. The regulator is designed to determine a difference between set and real values, to verify whether this difference lies within or outside a predeterminable tolerance range, and, in the event that the difference lies outside the tolerance range, to modify accordingly the light flux from the lighting elements which can be connected to the n output connections. At least one limit of the tolerance range depends on the actual light flux value.

The invention relates to a method for the sampling of biphase coded digital signals by reception means which have at least one signal input having switchable signal edge sensitivity or at least two signal inputs having different signal edge sensitivity for the reception of such signals. The signals to be received are sampled precisely once per data bit, namely during the transmission of the first half-bit. The signal edges (F1-F5) of each bit are utilized for synchronizing the signal input with the control signal and for detecting transmission errors. Each signal sampling (S1-S5) is followed by a time window (&Dgr;t) within which the reception of the signal edge of the present bit is expected and evaluated as permissible. The signal edge sensitivity of the at least one signal input is set as a function of the sampled logic level of the first half-bit of the respectively transmitted bit of the signal.

The invention relates to a starting-up method for a lighting system, which has a plurality of luminaries (L ; L ; L ; L ; L ; L ) which are fitted with lamps (LP ; LP ; LP ; LP ; LP ; LP ; LP ; LP ) and electric equipment for operating these lamps, a control device (St) for actuating the electrical equipment (B ; B ; B ; B ; B ; B ) and control elements (S) for controlling and programming the control device (St). During the starting-up phase of the lighting system, system initialization is carried out, during which each electrical equipment item (B ; B ; B ; B ; B ; B ) is assigned an individual appliance address, which ensures that the equipment (B ; B ; B ; B ; B ; B ) and the luminary (L ; L ; L ; L ; L ; L ) are identified by the control device (St). According to the invention, the individual address which is assigned to the equipment (B ; B ; B ; B ; B ; B ) by the control device (St) is transmitted by a brief interruption in the electrical contact to one of the lamps (LP ; LP ; LP ; LP ; LP ; LP ; LP ; LP ) in this electrical equipment (B ; B ; B ; B ; B ; B ).
