An LED converter () comprises a converter circuit () with potential separation (). The converter circuit () has at least one controllable switching means (). A control device () for switching the at least one controllable switching means () in a clocked manner is configured to modulate a switching frequency of the at least one controllable switching means () in order to transmit information across a potential barrier ().

LED converter and method for controlling a converter circuit of an LED converter

The invention relates to a device for operating LEDs, comprising a driver module and an LED module (), which is controlled by the driver module () and has at least one LED. The LED module () is fed a current by the driver module () via a first connection (), and a second connection () is present, preferably as a ground connection (GND). The device is characterized in that the LED module () is connected to the driver module () by means of a third connection (), which is designed as a data channel, a voltage fed by the driver module () being applied to the data channel.

Device for operating LEDs

The invention relates to a method for operating LEDs (), comprising a driver module () and an LED module () having at least one LED (), which LED module () is controlled by the driver module (), wherein the driver module () has a first connection (), which is designed to feed the LED module () with a current, and has a second connection () is present as earth connection (GND), wherein the LED module () is fed with a current by the driver module () via a first connection () and a second connection () is present as earth connection (GND), characterized in that the driver module () temporarily lowers the voltage at the first connection () and monitors the voltage at the first connection () and is designed to evaluate a change in the voltage at said connection as a transfer of information from the LED module ().

Device for LED operation

The invention relates to a method for programming an operating device for lighting, wherein the operating device comprises firmware and an interface for receiving external control commands for operating the lighting. This method includes at least partially programming the firmware of the operating device or the interface by transmitting additional information to the interface. This can conveniently be accomplished while the operating device is in operation. Typical lighting of the invention is the type that includes an electronic ballast for gas discharge lamps.

Method for programming an operating device for lighting means

A method for driving an electronically controlled lighting means operating device, by evaluating an output signal of a motion sensor which is connected to a supply voltage and outputs the supply voltage as an output signal as a function of the detection of a motion, and setting the electronically controlled lighting means operating device to one of a plurality of predetermined dimming levels as a function of an output signal of the motion sensor. At least one of the predetermined dimming levels is programmed or the output signal of the motion sensor is detected at a control input of a digital interface of the operating device.

Method and device for dimming lighting control devices to a predefined level

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.

Method for the monitoring of transmissions of a bidirectional interface

An interface () for a lamp operating device () has two input-side terminals () for the connection of bus lines or for connection with a button or switch, an evaluation logic () for the processing of signals present at the input-side terminals () and for the generation of output-side signals for the control of the lamp operating device (), and at least one electrical isolation element () to electrically decouple the input-side terminals () from the lamp operating device (). Thereby, the evaluation logic () is arranged on that side of the electrical isolation element () which is towards the input-side terminals (), and is supplied with voltage via the input-side terminals () of the interface ().

Interface for lamp operating units with low standby losses

An interface for a lamp operating device, in particular a ballast (EVG) for gas discharge lamps, has two input side terminals of a digital control input SE and a evaluation logic (AL) which is constituted for processing both digital signals applied to the terminals and also mains voltage signals. The amplitude of a mains voltage applied to the terminals is continuously settable by means of a voltage divider (ST) or a potentiometer. The amplitude of the applied mains voltage is converted into pulse width information (PWM) which in turn the evaluation logic converts into control commands, for example dimming setting values, for a ballast (EVG).
