Abstract: A device is provided for controlling an illumination device (50), including a control circuit (110) having an input (102) for coupling to a network voltage conductor (30) and an output (104) for coupling to a supply voltage conductor (40) of the illumination device (50). The control circuit (110) is designed to supply a supply voltage and control signals modulated onto the supply voltage to the illumination device (50) via the output (104). A button (120) influences the generation of the control signals. The control circuit (110) produces an internal supply voltage (Vint) from a voltage which reduces between the input (102) and the output (104) of the control circuit. In the non-actuated state, the button (120) bypasses the input (102) and the output (104) of the control circuit (110).

Abstract: An operating device (1) for light-emitting device (5), where the operating device (1) has an interface circuit (2) and a drive circuit (3), where the interface circuit (2) generates an interface signal (21, 31, 41, 51) depending on a control signal (Vn, 10), and where the drive circuit (3) drives at least one light-emitting device (5) depending on the interface signal (21, 31, 41, 51). The control signal (Vn, 10) is an AC voltage control signal generated outside the operating device (1). The interface circuit (2) detects overshooting of an upper threshold value of only one of two half-waves of the control signal (Vn, 10), and the interface circuit (2) generates a first signal pulse (22, 55) in the interface signal (21, 31, 41, 51) for each detection of overshooting of an upper threshold value and identifies overshooting of a lower threshold value for the other half-wave.

The output side of the transformer controls a switch, such as for example a power transistor, which modulates the desired digital signals onto a connected bus line.

Abstract: A method for the monitoring of transmissions in a transmission branch of a bidirectional interface, which besides the transmission branch has a reception branch standing in connection with the transmission branch, has the steps a) sending out of information by means of the transmission branch, and b) evaluation of defined characteristics of the sent information via the reception branch of the same interface, whereby preferably depending on the evaluation of the sent information a setting of parameters of the transmission branch is effected, so that future information is sent out with use of these parameters.

Abstract: A circuit and a method for controlling light emitting diodes (D1, D2) for illumination involve an inverter whose output frequency can be varied. The inverter includes two electronic switches (S1, S2) which convert an applied direct current voltage (Uo) into an alternating voltage. A load circuit is connected to the output of the inverter and includes a resonance element and at least one light emitting diode (D1, D2) whose brightness is controlled by altering the output frequency of the inverter.

Abstract: Process for the recognition of the rectifier effect appearing in a gas discharge lamp (G1, G2) and an electronic ballast, for the operation of gas discharge lamps (G1, G2), with which such a process finds employment. The electronic ballast includes a monitoring or control circuit (IC2) which monitors an operating parameter of a load circuit (E) of the electronic ballast, whereby this operating parameter corresponds to the lamp voltage or is dependent thereon. The monitoring circuit (IC2) integrates this monitored operating parameter over a full period and determines upon the presence of a rectifier effect if the integration result deviates from a predetermined integration desired value. Further, for the recognition of the rectifier effect, the duration of the positive and negative half-waves of the monitored parameter can be compared.
