    The present invention will now be described in more detail with reference to the attached figures.
    Fig. 1 is a schematic representation of an operating device of the present
    Invention.
    Fig. 2 shows a modular construction of an LED converter according to the present invention
    Invention.
    Fig. 1 shows an operating device 1, which is completely housed in a housing 6. The operating device 1 can also consist of several components, each with individual housings. The housing 6 is preferably made of metal or other material that can shield wireless communication from interference.
    The operating device 1 consists of at least one circuit 2 on a primary side and at least one circuit 3 on a secondary side with respect to a galvanic isolation 4. The at least two circuits 2, 3 are preferably intelligent circuits, for example an integrated circuit such as an ASIC or a microcontroller on. In this case, the circuits 2 on the primary side may be the same as or different from the circuits 3 on the secondary side. Preferably, the primary-side and the secondary-side intelligent circuit 2, 3 respectively controls one or more clocked components or components with a power actuator.
    In the example of FIG. 2, the circuit 2 controls, for example via a control module 8, a PFC converter 10 for active power factor correction. For example, the PFC converter 10 may be a boost plate PFC (Boost PFC, boost converter power factor correction). The PFC converter 10 may be fed from the input side via the terminal for power supply via an EMI filter 11. The EMI filter 11 is used to filter high-frequency interference. The PFC converter 10 can feed a potential-separated converter 9. The potential-separated converter 9 is shown here by way of example as DC / DC LLC converter (isolated resonant DC-DC converter). The potential-separated converter 9 preferably has a transformer which bridges the galvanic isolation 4. As a load 12, for example, one or more LEDs can be connected. Optionally, the operating device 1 can also have an actively controlled converter on the secondary side, which is controlled by the circuit 3.
    The operating device 1 may have an optional interface circuit 7 on the primary side, via which the operating device 1, for example, brightness commands can be supplied. The interface circuit 7 may be connected to the control module 8 or directly to the circuit 2. The control module 8 may have at least one high-voltage driver for driving at least one switch of the PFC converter 10 and / or the potential-separated converter 9.
    The circuit 3 can serve, for example, to detect a current through the load 12. The circuit 3 can also serve to read out information 13 (ISELECT) about the load, for example a nominal current, the information 13 being predetermined by a coding resistor. The circuit 3 can also serve to detect a temperature 14 (ITM) in the operating device 1 and / or on the load 12.
    The galvanic isolation 4 can be bridged for example by a transformer. In general, the galvanic isolation is a SELV barrier or a circuit that allows separation according to SELV.
    The galvanic isolation 4 is bridged by a radio channel 5. The radio channel 5 is set up by two radio interfaces 2A and 3A, respectively. A radio interface 2A is preferably assigned to the circuit 2 on the primary side, another radio interface 3A is assigned to the circuit 3 on the secondary side. The radio channel 5 connects the at least one primary-side circuit 2 and the at least one secondary-side intelligent circuit 3 unidirectionally or bidirectionally with each other. Preferably, the radio channel 5 allows bi-directional communication between the primary-side and secondary-side circuits 2, 3. The radio channel 5 between the two circuits 2, 3 is preferably an internal communication within the housing 6, thereby avoiding external disturbances.
    The radio channel 5 can be realized as shown in Fig. 1 by two antennas 2A and 3A. In this case, a first antenna 2A is connected at least to a primary-side circuit 2, and a second antenna 3A is connected at least to a secondary-side circuit 3. Each circuit 2, 3 can be connected to its own antenna 2A, 3A. However, it is also possible to provide only one antenna 2A on the primary side and one antenna 3A on the secondary side for bridging the electrical isolation 4.
    Each antenna 2A, 3A may be a separate component. However, each antenna 2A, 3A for radio communication via the galvanic isolation 4 can also be arranged in a chip housing of the primary-side or secondary-side circuit 2 or 3, or be formed on a printed circuit board or circuit board of one of the circuits 2, 3. An antenna 2A, 3A can be formed in the manufacturing process simultaneously with circuits of the circuits 2, 3.
    The first antenna 2A and the second antenna 3A are preferably arranged so that they are arranged at a position of the respective circuit 2, 3, which is as close as possible to the galvanic isolation 4. Ideally, the distance to be crossed for the radio path from the first antenna 2A to the second antenna 3A is merely the distance prescribed for safety reasons for the galvanic separation 4 as a spatial distance. Preferably, the distance to be overcome is in the range of about 0.5 cm to 5 cm, more preferably about 1 cm. Due to the distance to be overcome and the shielding by the preferably metallic housing 6, the radio power for the internal communication between the primary-side circuit 2 and the secondary-side circuit 3 can be set very low. The radio power may preferably be in the range of 1 mW to 100 mW, more preferably in the range of 1 mW to 10 mW.
    Preferably, each antenna 2A, 3A, or the radio channel 5 serves not only for the internal communication between the circuits on the primary side and the secondary side, but also as an antenna 2A, 3A or radio channel 5 for an external communication, for example as a Type of wireless DALI bus. Thus, the operating device 1 can be transmitted wirelessly commands from the outside. The commands may be, for example, control commands for the operating device, such as ON / OFF, lighter / darker, and the like. The external control of the operating device 1 can thus be done via radio, in particular via the same radio channel 5 or via the same antenna 2A and / or 3A, which is also used for the internal communication between the circuits 2, 3 on the primary side and the secondary side. At least one antenna of the two antennas 2A and 3A may be configured for bidirectional external communication.
    At least one antenna of the two antennas 2A and 3A may be configured for communication as a DALI interface for a wireless DALI bus. It can be provided that a radio power for the internal communication and the external communication is different. For example, a radio power for external communication may be in the range of 0.1 to 1 watt, preferably up to 100 mW. The operating device 1 may have a control circuit which controls the radio power depending on the communication. The control circuit can, for. B. for different data or information that is communicated, stored or stored different wireless services that selects and adjusts accordingly.
    The radio channel 5 can be realized for example by near field communication, Bluetooth, WPAN or WLAN. Radio communication according to the present invention is clearly distinguishable from purely inductive coupling.
    2 shows an example of an operating device 1 which is designed to operate light-emitting means such as light-emitting diodes or another load ("load 12.") The load 12 is actuated on the secondary side via a circuit 3, in this example a pC At least on the primary side a connection to a voltage supply ensues, which can take place, for example, via a filter (EMI filter 11), a power factor correction circuit (PFC converter 10) and a potential-separated converter 9 as well as controlled by a primary-side circuit 2 Circuit 2 may for example be supplied via the interface circuit 7, a dimming signal for dimming the lighting means.
    The radio channel 5 overcomes the SELV barrier 4 for the communication of the circuits 2 and 3. About the radio channel 5, for example, the information from the circuit 13 or the temperature 14 are transmitted to the circuit 2. Via the radio channel 5, for example, commands or signals received by the circuit 2 via the interface circuit 7, such as brightness commands, can be transmitted to the circuit 3.
    It is the feature that the bulbs on the secondary side with respect to. The galvanic isolation can be supplied in such a way to understand that the bulbs are arranged on the secondary side of the galvanic separation and there are supplied accordingly.
    The present invention provides an operating device 1 in which a galvanic isolation 4 between a primary side, which has at least one circuit 2, and a secondary side, which has at least one circuit 3, is bridged by a radio channel 5. This allows a communication from the primary side to the secondary side and vice versa via radio. An optocoupler or transformer for communicating via the galvanic isolation 4 (eg SELV barrier) can be omitted. As a result, the operating device can be built cheaper and more compact.
