Definitions
- the present invention relates to a control device for a component of a lighting system and a method for protecting the information stored in a transponder of the control device.
- lighting systems can have other components such as sensors or actuators, switches and dimmers.
- operating devices that generate a suitable operating voltage or a suitable current for the lamps of the lights
- the function of the lamps can be monitored and the lamps can be started and/or dimmed and switched off.
- sensors which, for example, record the movement of objects and/or the ambient brightness
- the lamps can be switched on/off automatically when a person is present or absent, or the dimming of the lamps can be automatically adjusted to the ambient brightness.
- operating devices for lights with light-emitting diodes often contain control devices which can receive control data for setting operating parameters, such as the maximum output current to the light-emitting diodes or the color temperature, from the outside.
- DE 10 2016 10 414 A1 discloses a control device for a component of a lighting system, which has a transponder by means of which control data can be received from a transmitter device when the control device is switched off and can be stored in the control device.
- a control device enables configuration before the control device is installed at its place of use or connected to the component to be controlled. The configuration can be carried out on site or by the manufacturer and can be carried out separately for each device.
- EP 3 799 358 A1 discloses a device by means of which a large number of devices located in a box can be configured in one operation.
- the devices are arranged or packaged in such a way that data can be transmitted between a stationary transmitter and the transponders. After connecting the devices (control devices) to the power supply or switching on, the data stored in the transponder are read out and used for control.
- the configuration of the devices is only performed prior to their installation, so that the ability to configure them further after installation or commissioning is unnecessary or even undesirable for security reasons.
- Unauthorized reading or manipulation of the stored data can be made more difficult by means of data coding or the use of access codes.
- this requires special transponders or a complex implementation of coding in the control device.
- the invention is based on the object of specifying a device and a method which reduce the problems described.
- the object is in particular to provide a control device and a method with which unauthorized access to the stored data or the writing of new data can be prevented in a simple manner.
- a control device for a component of a lighting system has a transponder, a control device and at least one mechanical element for access protection.
- the transponder is designed to receive and store data from a transmitting device by means of an antenna at least when the control device is switched off.
- the control device reads out the data stored in the transponder at least after switching on the control device and uses it to control the component.
- the mechanical element is configured to interfere with or damage the antenna after the controller is connected to the component.
- the disruption or damage to the antenna means that radio transmission between the transponder and an external reading/transmitting device is no longer possible, meaning that the reading/transmitting device cannot access the transponder memory.
- the transponder thus no longer represents a potential security gap.
- the disruption or damage can occur after data has been transmitted by the transmitting device and before the control device is put into operation, with the disruption or damage preferably being automatic (unavoidable) takes place during the installation of the control device or the mechanical element has to be brought into a certain position for a necessary installation step in which the antenna is disturbed or damaged by the mechanical element.
- the data stored in the transponder's memory can be read out by the control device when the control device is connected to the component and switched on.
- the disturbance can be a shield that prevents the emission or irradiation of electromagnetic waves and/or a detuning of the resonant frequency of the antenna. If the antenna is damaged by the mechanical element, it can be bent, short-circuited and/or severed.
- the antenna can be the antenna of the transponder or an antenna coupled to the antenna of the transponder which, for example, as described in DE 10 2018 111 711 A1, enables signal transmission to the transponder (NFC chip) arranged deep inside the housing.
- strain relief is required as a mechanical protective device that protects flexible electrical lines (connecting cables) from being torn out.
- At least one mechanical element can be such a strain relief, with the strain relief having a metallic shield for the antenna or at least partially consisting of metal (e.g. screws, clamp) which interferes with the antenna.
- the strain relief can be arranged appropriately close to a fault and/or in the send/receive direction.
- the strain relief can be pivotable or displaceable with respect to the antenna, the strain relief being pivotable or displaceable into a position in which the electrical lines can be fixed by the strain relief and/or connected to the control device and in which the metallic shielding or the metallic Screws and/or clamps interfere with the transponder antenna.
- the strain relief can be mountable on the control device, for example by means of screws or a snap connection, with the metal shielding or the screws and/or clamp interfering with the antenna of the transponder when the strain relief is mounted on the control device.
- the control device can have a connection terminal for electrical lines, the at least one mechanical element being a cover for the connection terminal and the cover having a metallic shield for the antenna.
- a mechanical element can be an electrical plug for connection to the control device, which has metallic shielding for the antenna and interferes with it when plugged in or causes a detuning of the resonant frequency of the antenna when plugged in.
- a mechanical element can be a housing part of the component, which has a metallic shield for the antenna.
- the component can be a light and the control device can be part of an operating device for lamps, with the antenna being arranged on a side of the operating device that rests against the housing part or at least faces the housing part when the operating device is mounted in the light, so that the metallic lamp housing shields/blocks the antenna.
- a mechanical element can be a screw for fastening the control device to the component or another supporting element, for fastening a cover of the control device or for fastening a strain relief of the control device, the screw being made of metal and/or being designed to do so destroy antenna.
- the antenna can have a predetermined breaking point, with at least one mechanical element being designed to act on the predetermined breaking point in order to damage the antenna.
- the mechanical element can be designed as an operating element (e.g. push button, rotary or slide switch).
- the control element has the sole function of preventing data transmission, with the control element acting on the predetermined breaking point and damaging the antenna when actuated by a user. Thus, even before installation, for example by the seller, the possibility of data transmission can be permanently blocked without having to carry out installation steps.
- the mechanical element may be a cover for electrical connections of the control device, the cover being adapted to act on the frangible point to damage the antenna when the cover is opened.
- the mechanical element is part of a holding device to which the control device can be attached.
- the control device has at least one fastening element for fastening the control device to the holding device.
- the at least one fastening element is designed to position the control device with respect to the mechanical element in such a way that the mechanical element interferes with or damages the antenna when the control device is fastened to the holding device.
- the holding device can be a mounting rail, in particular of a light line system, or the housing of a device, in particular of the component.
- the mounting rail or the housing can be made at least partially of metal, so that the antenna is shielded by the metal mounting rail or the metal housing when the control device is attached to the mounting rail or to/in the metal housing.
- the control device can have a housing, with the antenna being arranged on a surface on the inside or outside of the housing which, in the mounted state, rests against the metal support rail or the metal housing or at least faces this.
- the mechanical element can be an elevation (bolt, pin or edge) on the mounting rail or the housing, which acts directly or indirectly on the antenna mechanically when the control device is attached, in order to damage the antenna.
- the at least one fastening element can be a bore/opening for a screw or a snap hook for fastening the control device.
- the data can contain at least information on the configuration of the control device itself and/or information on the configuration of the component to be controlled by the control device, with the control device being designed to configure the control device and/or the component to be controlled by the control device in accordance with the information.
- the transponder can be an NFC (Near Field Communication) transponder or an NFC transponder based on RFID (radio-frequency identification) technology.
- a method for preventing data transmission between a transmitter and the control device described has the step of activating the mechanical element for interfering with or damaging the antenna of the transponder before or while the control device is connected to the component.
- the data sent by the transmitting device can be received and stored by the transponder before the mechanical element is activated, with the data stored in the transponder being read out by the control device after the mechanical element is activated.

- the control device 10 can be designed as a processor, a microprocessor, a controller, a microcontroller or an application-specific special circuit (ASIC) or a combination of the units mentioned and can receive control commands for switching on/off and/or dimming via the data bus line.
- ASIC application-specific special circuit
- control device 1 At the in own 1 shown in a plan view control device 1 are not yet connected. Although the control device 1 is not yet ready for operation or is not connected to a power supply, information for configuring/parameterizing, such as the maximum current to be delivered to the lamps, the color temperature to be set and/or a network or bus address, can be transmitted by the transmitter 2 are transmitted to the control device 1 via the wireless connection 3 .
- the transmitter 2 For such a coupling/connection, the transmitter 2 generates alternating magnetic fields with a short range or high-frequency radio waves, whereby the (passive) transponder 8 is supplied with energy and the information received from the transmitter 2 is stored in a non-volatile, possibly rewritable memory (not shown ) saves.
- the transponder 8 can store information/data (e.g. identification/authentication information) that can only be read via the wireless connection (R/O) and data (e.g. preset parameters) that can be both read and overwritten/modified (R /w).
- the transponder 9 can be an NFC chip or an RFID transponder, in particular an NFC transponder based on RFID technology, which uses a special coupling method that is standardized for separate frequency ranges and short-distance communication.
- control device 10 If the control device 1 is supplied with power, for example during commissioning, the control device 10 reads the stored data from the memory of the transponder 9 and parameterizes/configures the operating device according to the data read out.
- the control device 1 has a second connection terminal (not shown) for connecting the lamps, a cover 11 (protection against accidental contact) that can be slid in the direction of the antenna 8 of the transponder 9 for the second connection terminal, and a metal shielding 12 that can be slid from the cover for the antenna 8.
- the cover 11 and the metallic shielding 12 form a mechanical element that serves both as protection against accidental contact and as protection against unauthorized access to the stored data or unauthorized writing of new data.
- Fig. 1 shows the control device 1 in a state in which the control device 1 can be configured by means of the transmitter 2 because the metal shielding 12 is in a position in which it does not interfere with the antenna 8 and in the light source is not connected to the Control device 1 or the operating device can be connected because the second connection terminal is covered by the cover 11 .

- Fig. 2 shows the control device 1 in a state in which the lamps can be connected to the control device 1 or the second connection terminal 14 because the cover 11 has been moved, and in which the data stored in the transponder 9 from the transmitter 2 or a other transmitter / reader can no longer be read or manipulated because the metal shielding 12 was pushed with the displacement of the cover 11 in front of the antenna 8 and this now interferes.
- the cover 11 can be designed in such a way that the cover 11 cannot be moved or can only be partially moved in the direction of arrow F1 when lines are connected to the second connection terminal 14 in order to prevent unauthorized data access.
- the metal shielding 12 can be attached to the cover 11 such that the metal shielding 12 exposes the antenna 8 again by moving the cover 11 in the direction of the arrow F2 shown in FIG. 2 . In this way, for example, when the control device 1 is being repaired by the manufacturer, data could be read out with the transmitter 2 and/or new data could be stored.
- the metallic shielding 12 can only be displaced from the cover 11 in the direction of the arrow F1, so that the disruption of the antenna 8 by the metallic shielding 12 cannot be reversed.
- the manufacturer or seller can move the cover 11 in the direction of the arrow F1 in order to ensure that the stored data cannot be accessed by the transmitting device 2 (not even by the fitter).
- the antenna 8 and/or the area surrounding the antenna 8 is designed in such a way that the radio signal can only be received by the transmitter 2 via the opening that can be closed by the metallic shielding.
- the cover 11 covers only the second connection terminal 14 or releases it with interference from the antenna 2 .
- the first connection terminal 4, which has the mains connection L, N, can be covered by the cover 11 in order to ensure that data access via the wireless connection 3 is not possible after the control device 1 has been connected to the mains voltage.
- the disruption of the antenna 8 by the metallic shielding 12 can be a shield with which the emission or irradiation of electromagnetic waves is prevented, or simply a detuning of the resonant frequency of the antenna 8.
- the mechanical element and the antenna 8 can be designed in such a way that the antenna 8 is damaged (e.g. bent, short-circuited and/or severed) when the cover 11 is moved in the direction of arrow F1.
- This has the advantage that the mechanical element does not have to have any metallic objects.
- control device 1 can have at least one hole for a screw for fastening the control device 1 at the installation site or a component (e.g. strain relief, cover) of the control device 1, which leads through the antenna or is arranged close to the antenna, so that when Fastening the screw will damage or interfere with the antenna.

- the fastening element 16 has an opening 21 for the wireless connection 3 in the area in which the antenna 8 is arranged with the transmitter 2 on.
- these can be arranged next to one another on a table or in a box in such a way that the openings 1 are directed towards the transmitter 2 or towards the outside of the box.
- the 4 shows the control device 1 mounted on a metal plate 22 by means of two screws 23, 34 and nuts 35, 36.
- the plate 22, which can be part of a lamp housing or a mounting rail of a light strip, interferes with the antenna 8 or closes the opening 21, so that no wireless connection 3 with the transmitter 2 is possible and the data stored in the memory of the transponder 9 cannot be read or manipulated by the transmitter 2.
- the antenna 8 and/or the area around the antenna 8 is designed in such a way that the radio signal can only be received by the transmitter 2 via the unsealed opening.
- the wireless communication function of the transponder is not locked until the control device 1 is attached to the metal plate 22 .
- the housing 15 can be displaceable with respect to the fastening element 16 in the main direction of extension of the fastening element 16 between a configuration position and an assembly position, with the opening 21 being arranged above the antenna 8 in the configuration position, but one of the two recesses 17, 18 through the housing 15 is covered and in the assembly position one of the two recesses 17, 18 is not covered by the housing 15 and the opening 21 is not located above the antenna 8 or the antenna 8 is disturbed by the fastening element 16.
- the wireless communication function can be blocked by an irreversible displacement, if necessary, and the plate 22 does not have to be made of a metallic material to achieve the blocking.
