Description

ACTIVATING AND DISABLING THE RECEIVING UNIT OF A LIGHTING DEVICE

DESCRIPTION

The invention relates to a lighting device with a

Transmitting device and a lighting means, wherein the

Transmitting device is arranged in or directly on the light source and is designed to transmit a wireless signal with specific for the transmitting device identification data wirelessly, wherein the transmitting device is a

Receiving unit, which is formed, a

each of at least two operating states, namely an activated operating state, in which the

Receive unit is ready to receive data from one

Receive data source and a disabled one

Operating condition. The invention further relates to a method for operating a transmitting device from a

Light-emitting device having lighting, wherein the

Transmitting device is arranged in or directly on the light source and a radio signal with for

Transmitting device specific identification data wirelessly emits, wherein the transmitting device by means of a

Receive unit in an activated operating state of the receiving unit receives data from a data source, wherein the receiving unit occupies a respective one of at least two operating states, namely the activated

Operating state in which the receiving unit is ready to receive, and a deactivated operating state.

Lighting devices and methods of the generic type as well as transmitting devices of the generic type are known in the art in the art, so that it does not require a separate documentary evidence for this purpose. With lighting devices rooms, for example, outside or inside buildings, lit in a predeterminable manner to enable or support the intended use. When Lighting devices are increasingly used lighting devices, which in addition to a light source, which emits light in a predeterminable manner, also have a transmitting device, which is at least adapted to the specific

Send identification data wirelessly, for example, by radio. Preferably, this is

Transmitter configured to transmit the signal in the manner of near-field radio. To broadcast the radio signal, a wireless standard, such as Bluetooth, WiFi, ZigBee or the like, can be used. Such a transmitting device is also referred to in the art as a "beacon".

So-called beacons can be combined with lighting devices to light-specific or other information or data by means of their radio signal

provide. Beacon technology is based on a transmitter system or a transmitter-receiver system. A beacon (too beacon, beacon or beacon transmitter) is a small, mostly battery-powered

Transmitter which transmits a signal in, preferably definable,

Sends out time intervals, for example based on a Bluetooth Low Energy Standard (BLE). The signal of a beacon is distinguished by the specific identification data, which includes, for example, a unique identification number, for example, universally unic identifier (UUID). Beacons can be used to

Objects and / or locations, in particular digital,

Assign identification. Objects where a beacon is installed, as well as places where a beacon, for example on a wall or a ceiling, is installed, can thus be replaced by communication terminals,

For example, smartphones, laptops and / or the like, are identified in the signal field of the beacon. With the help of a beacon, for example, a location can be identified or a location can be carried out. By arranging one or more beacons in a predetermined area, for example one Building area or the like, a kind of radio-based raster can be provided that it is in the

Area located communication terminal by means of its radio interface, in particular BLE interface, as well as appropriate evaluation options allowed to own

Position to determine. The specific identification data of the installed beacons give a location an identifier, on the basis of which the communication terminal, at least

approximately, can determine the position. Basically, at any rate a transmission range of a respective beacon can be determined. By suitable evaluation, for example by using predetermined algorithms or the like, the accuracy of the determined position, for example by evaluating a signal strength and / or the like, can be improved. Preferably, the

Communication terminal access this data on a data storage, for example via a communication network such as the Internet and / or the like. The data store may be, for example, a cloud server or the like. Here, for example, the identification data and a

assigned position in a map. Of the

Data memory can also be present at least partially on the communication terminal. If the communication terminal comes into communication range with the transmitting device or the beacon, it can determine its own location, for example via a server query, on the basis of the determined specific identification data. By using further signals from further transmitting devices or beacons, the accuracy can be improved by means of locating algorithms; in particular, a distance can be determined from a received field strength of the respective signal of the transmitting device or of the beacon.

Basically, in the lighting technology at

Lighting devices of the generic type

Be installed transmitting devices or beacons. In particular, the advantage can be used that a light installation permanent energy access

can provide to supply the transmitting device or the beacon with electrical energy. This results in an advantage, namely that the transmitting device or the beacon does not require its own energy supply in the form of a battery and thus correspondingly

Maintenance costs can be saved. In addition, this embodiment allows that settings of the transmitting device or the beacon can be selected, which have a high energy consumption without this having to affect the life of the beacon need. In addition, installation processes of such transmitting devices or beacons and the lighting technology can be standardized.

Another advantage is a defined locking position of the transmitting device or the beacon, the

is preferably selected such that the transmitting device or the beacon is protected from manipulation.

As a result, a location can thus be assigned a reliably secure identifier.

An overview of potential uses of the integration of a transmitting device or a beacon into one

Lighting equipment can be taken from the following list:

- It can supply the energy of the light installation

instead of a power supply can be used by a battery, for example, life cycle costs of

Transmitter or the beacon

to reduce .

The electrical power supply of the lighting device can be used to transmit transmission parameters of the signal of the transmitting device or the beacon to a

Service and not to adapt to an available amount of residual energy or parameters of the battery.

For example, frequent transmission cycles produce a high Accuracy of a particular service, however, also leads to increased energy consumption.

The replacement of the battery conventional

Transmitting devices or beacons harbors

Risks, for example with regard to handling errors.

A non-availability of services may be due to an uninterruptible power supply of the

Transmitter or the beacon are avoided.

An installation location below a ceiling can

be advantageous for a signal propagation of the signal of the transmitting device or the beacon.

An installation location below the ceiling can do that

Overall system more robust against disturbances or shadowing by other objects at the height of one

Corridor level as opposed to an installation of

Send device or the beacon even at the level of the hall level.

The transmitting device or the beacon can be protected against manipulation or foreign access, whether inadvertently or wantonly.

A lighting system as well as services such as

Example location services or the like can be offered as a complete system "from a single source".

There is also the possibility to use a secure communication network of the

Lighting system, for example, the

Transmitter or the beacon

configure or transmit facilities

or to network the beacons with each other. A standardization of installation processes of transmitting devices or beacons and the

Lighting system can be enabled.

Furthermore, there is the possibility of coupling to other system elements of a peripheral

Building infrastructure, in particular controllable

Devices, via the communication network of the Lighting system, for example, security elements or the like.

- It can be a visually appealing lighting system

be provided because the transmitting device

or the beacon not visible in the respective lighting device or in

Lighting system can be arranged.

A beacon can be used as a transmitting device in a

Be integrated lighting device of a lighting system. The lighting system may include a plurality of

Lighting devices include. The lighting device comprises, in addition to the beacon, one or more lighting means which provide the desired lighting function. The beacon and the lighting device are preferably in

Communication connection with each other. The beacon is

preferably arranged integrated in the lighting device. So it does not need a separate housing for the beacon

to be provided. As a result, the beacon can be arranged protected at the same time so that the intended function can be provided with high reliability. Further lighting devices of the lighting system are preferably identical to this lighting device.

The transmitting device or the beacon is

designed to transmit a signal wirelessly, namely the radio signal, with specific for the transmitting device or the beacon identification data. Preferably, the transmission takes place by radio using a BLE

Standards. The transmitting device or the beacon preferably also comprises a control unit which

in particular may comprise a computer unit and a memory unit. In the memory unit an executable computer program is stored, which is ready for the computer unit, so that by means of the computer unit

predetermined control function can be achieved. The transmitting device or the beacon can also be connected via a communication connection to further local

Be connected transmitting devices or beacons. The communication connection is preferably also designed as a wireless communication connection, in particular according to the BLE standard. But it can also be at least partially wired. The communication link between the beacon and the other beacons is bidirectional, for example. But it can also be at least partially

be unidirectional.

In addition, the transmitting device or the beacon can be connected via a further communication connection to a data infrastructure device. The

Data Infrastructure may be the controller of the

Lighting system, in particular the

Lighting devices of the lighting system serve. The infrastructure device may be, for example, the Internet or else a central service server. The

Data infrastructure device can also serve for the control and / or transmission of data. The local beacon of the lighting device can be designed as a pure transmission device in the manner of a broadcasting operation or as a combined transmission-reception device.

The signal of the transmitting device or of the beacon can be received by means of communication terminals, such as a smartphone, a LAPTOP and / or the like.

According to an example of use, users or devices may have the challenge, if necessary

having to navigate within an area, navigate or find other local digital services, such as apps, app functions,

Google Maps, Lightify, lighting control and / or the like. The lighting system with built-in beacons in a given area may allow for these usage potentials a locating or orientation system. With a realizable self - location of the

Communication terminal services can now be provided, for example, a navigation, a provision of location-specific information and / or the like.

One aspect of beacon technology is the ability to configure typical parameters such as signal strength, transmit interval and / or the like of the beacon. With different configurations can

various application scenarios are supported individually. For example, if a high quality of service is desired in terms of accurate localization at short distances, for example in indoor navigation, very short transmission intervals may be to be configured, for example.

Particularly in the case of digitally controlled systems, for example using Digital Addressable Lighting Interfaces (DALI), it should be possible to unambiguously identify which luminous means or which luminous device is arranged at which location in order to use digital

Light control an exact control of

Lighting devices or their lighting in a certain area to allow. The

Lighting devices require a unique address, which reflects their position in a service area. The expert calls such an assignment of

Lighting equipment to appropriate positions

or "picking" addresses, in which case several pieces of information must be merged, namely the unique identification data of a respective one

Lighting device, an installation location of the respective

Lighting device in a predetermined range, that is, a physical address of the lighting device, as well as an identifier of the lighting device, that is, for example, their digital address. The digital address of a lighting device can usually be via powerline communication or a similar one

performance-based communication connection over the

Energy distribution to a controller or

Data processing to be transmitted. The lighting device or a ballast of the lighting device can thus register with their digital address at the control. But this is not the information yet

Available at which physical point in the service area, the lighting device is actually arranged. These

Information is required, however, if only a defined area to be illuminated, for example, only one

Meeting room or part thereof or the like. Currently, lighting devices or

Bulbs and their location are usually not easily identified electronically.

Typically, just about a sticker or a

Imprint be recognized, for example, on a housing of the lighting device, what kind of a

Lighting device or the light source is. Another complex possibility is to flash each digitally registered lighting device within the system individually and manually

Mark position information in a layout.

In order to efficiently connect lighting devices and / or light sources within the system to a light management system (LMS) as a control, it would be advantageous to use one or more electronic or digital ones

Have identification data for the detection of the entire system or individual components of the overall system available. A specific problem is also that usually in an installation plan positions of

Lighting devices or bulbs are set for a lighting area as a service area. This dictates to an installer which of the supplied or commissioned lighting devices, for example with respect to a luminaire type or the like, at which position of the service area, for example the building, should be arranged according to the installation plan.

Location-based services or services, such as

Example navigation of a user or the like, by means of beacon should be available to the user in a predetermined area, preferably permanently and without restriction. This requires in addition to an uninterruptible power supply and a regular maintenance or possibly also updating

Computer programs such as the firmware or

like. In particular, firmware updates of technical systems are of great importance. They are usually used for troubleshooting, performance optimization and possibly also for extending the functionality of the

technical system. For example, mistakes,

so-called bugs can be fixed, whereby the reliability can be increased. In addition, you can

Vulnerabilities are closed or technical functions of the lighting system can be subsequently enabled or disabled. Thus, there is a need to perform firmware updates in regular, especially situation-specific, intervals. However, such maintenance requires access to the transmitting device or the beacon. The following issues may apply when using beacons:

- Batteries are currently being used to power the beacons. The need to change these batteries in regular cycles, resulting in a high cost and correspondingly high

Life cycle costs for the respective beacon. - A high quality service, such as a high positioning accuracy, a long range, a short transmission interval and / or the like, usually leads to a correspondingly high demand for electrical energy for the transmitting device or the beacon, so that the battery at a

Battery-operated Beacon after a short time, for example, after a month, must be replaced to the normal operation beyond

to be able to maintain.

- Each replacement of a battery also carries the risk that the functionality of the positioning system can be adversely affected by a change in position or incorrect handling of the beacon.

- In addition, there is the problem that an operator does not notice a lack of energy of the beacon

or the beacon does not find again when the beacon does not have sufficient amount of residual energy to send out his radio signal.

- The services of the beacon for example in terms of

Navigation or the like should, however, preferably be made available to the users permanently. For this is an uninterruptible

Energy supply desirable.

An attachment or installation of the beacons on or in or as part of

Lighting device would be compared to one

battery-powered beacon enable the

Power supply of the lighting device, for example, a ballast of the light source or the like to use for its own power supply of the beacon and thus at least partially substitute the battery of the beacon and the associated

To counteract problems.

Transmitting devices or beacons of the generic type are nowadays usually also equipped with a receiving unit, which is an external Control unit allows to communicate with the transmitting device or the beacon in communication and data from the external control device to the transmitting device

or to transmit the beacon. These data are preferably used to configure the transmitting device

or the beacon, for example, with respect to parameters that the sending of the specific

Information data or the like, but also

Can affect parameters or settings of the light source of the lighting device. In addition, a variety of other settings can be realized.

During normal operation of the transmitting device in order to be able to send out the specific identification data, however, the operation of the receiving unit is generally not required. This not only requires energy, but it also opens the possibility to change unwanted or accidental settings of the transmitting device or the lighting device. For this reason, it is usually customary that the receiving device of

Transmitting device in a delivery state of

Transmitter is disabled. For example, this is provided by the proprietary iBeacon® standard from Apple Inc. In the delivery state is the corresponding

Transmitting device or the corresponding beacon according to this standard in a pure transmission mode by only the specific identification data are broadcast according to the broadcast principle of the transmitting device or the beacon. That is, the receiving unit is deactivated. This operating state is also

Called Connectable mode. In this operating state, the transmitting device can not receive any data. The

Receiving unit is in such transmitting devices

or beacons preferably also designed for near-field radio, for example based on the BLE standard.

However, it is required or desired, for example, with regard to a change of a Sendeinterval or even a strength of the radio signal or the like to make adjustments, but this requires a communication link to the respective

Transmitting device or the beacon so that the corresponding changes can be made. The standard iBeacon® provides for a send-receive mode, also called Connectable mode, in which the

Receiving unit of the transmitting device or the beacon is activated and thus by receiving

corresponding configuration data

or can be changed. Of course, this is also done, of course, wirelessly.

In order to switch the transmitting device from the pure transmission mode in the transmission-reception mode, is in such

Transmitting devices provided that they have a manually operable switch, if necessary

can be operated accordingly by a service staff. Of course, this requires that the appropriate service personnel on the one hand knows the exact position of the transmitting device and on the other hand also has access to the transmitting device at the corresponding position. Only then can the service personnel also operate the manually operable switch, by means of which the receiving unit of the

Transmitter can be activated. Is the

Receiving unit activated, it is possible by means of the external control device, which may be, for example, a laptop, a smartphone or the like, with the

Transmitting device using the receiving unit in

Communication link and make the appropriate configuration. The to the transmitting device

established communication connection is preferably bidirectional, so that at the same time also parameters, for example with respect to certain operating conditions of the transmitting device and / or the lighting device can be queried and / or the like. However, if the transmitting device is arranged directly in or on the lighting device, the manual actuation of the switch or the activation of the transmitting unit is sometimes difficult, if not impossible. Due to a particular integrated arrangement of

Transmitting device in the lighting device can even

be provided that a manually operable switch is no longer provided on the transmitting device. A change of the operating states of the transmitting device or the operation of a mechanical switch is after a

Installation of the lighting device, if at all, only very cumbersome.

Even with the use of alternative beacon standards, such as

Example Eddystone® the company Google, Alt-Beacon or

Likewise, it makes sense for reasons of safety and / or energy consumption, that the transmitting device is in a delivery state exclusively in non-connectable mode, that is, that the transmitting device

exclusively the specific identification data

sends out and no receipt of data by means of

Receiving unit allows.

In addition, it can be provided that the

Transmitting device in the delivery state in one

Energy saving mode is as operating state, which for

Example in the context of a production of an overall system is activated, for example, an energy buffer of the entire system in the context of a logistics before a

To protect deep discharge. A change from this

Energy-saving mode in a configuration mode and / or an operating mode should also be enabled.

The invention is therefore based on the object, a

Lighting device and a method of the generic type to the effect that a simplified

Configuration of the transmitting device can be achieved. As a solution, the invention proposes a method and a system according to the independent claims.

Further advantageous embodiments will become apparent from the features of the dependent claims.

With regard to a generic lighting device is proposed in particular that the lighting device is a detector unit for detecting an operating state signal provided by an external unit and the

Having control of the operating state of the receiving unit depending on the detected operating state signal.

With regard to a generic method, it is proposed in particular that one of an external unit

provided operating state signal by means of a

Detector unit is detected and the receiving unit is controlled depending on the detected operating condition signal in terms of their operating state.

The invention is based on the idea that an operating state signal can be detected by means of the detector unit, which can be used to assume a predetermined one of the at least two operating states or to switch between these operating states. This can be easily created a way to switch the transmitting device between operating conditions, in particular to activate the receiving unit

or disable. As a result, it is no longer necessary to provide a mechanical switch in order to be able to assume the activated operating state of the receiving unit. This has the great advantage that it no longer matters where the transmitter is positioned

In particular, it no longer needs access for service personnel. By the

Operating state signal can, preferably without intervention, the respective desired operating state of the receiving unit can be achieved. The invention thus makes it possible to have a Change the operating conditions not via a mechanical interface, such as the switch to make, but

instead use alternative mechanisms. When changing the operating modes, for example, from a pure transmission mode in a transmission-reception mode and also

reversed be changed or switched.

In this way it can be achieved on the one hand that the transmitting device always in one of the respective

For example, to minimize energy demand in non-connectable mode, it can be configured during one

Installation of lighting equipment in a service area and / or the like. On the other hand, it can be achieved that switching between the operating modes accordingly

predetermined standards, such as iBeacon® or the like can be maintained. Finally, a great user experience can be achieved because of

mechanical interfaces at the light installation,

in particular the lighting device or the

Transmitting device can be dispensed with.

The receiving unit of the transmitting device is preferably designed integrated into the transmitting device. It particularly preferably uses as far as possible units of

Transmitting device, which also serve to broadcast the radio signal, such as the antenna, a power supply for the transmitting device, a control unit of

Transmitting device and / or the like. This allows the

Receiving unit with little effort to be integrated into the transmitting device. The receiving unit is preferably

configured to be in communication with the external unit in a predetermined area in order to be able to exchange data in this way. The predefined area can at the same time also be the area in which the radio signal can be received by communication terminals.

Preferably, however, the predetermined range is smaller than the reception range for the radio signal. The receiving unit makes it possible to receive a communication signal, for example by radio, in particular by local radio,

for example, from the communication terminal as an external unit or from a separate external control unit as an external unit, which is in communication range to

Receiving unit or the transmitting device

located. Sendereinrichtungsseitig or

On the beacon side, a corresponding communication signal of the external unit can be evaluated and detected as an operating state signal and, in particular due to the data thus obtained, additional data can be transmitted in addition to the radio signal, for example with regard to a function of the lighting device

Lighting device and / or the like. In addition, parameters relating to the operation of the transmitting device and / or the lighting device can be queried or

be changed accordingly.

The data source may be provided by the external unit itself or by the communication terminal.

In addition, however, the data source can also be a remote database that can be brought into communication with the transmitting device via a communication network. The data source may be suitable data for setting parameters of the transmitting device and / or the like

include. Furthermore, the data source can also be called up by an at least partially executable computer program

ready to run, for example, a firmware update or the like.

The detector unit may be formed as a separate unit, which is arranged on or in the lighting device. It can be encompassed by the transmitting device, in particular by its receiving unit. Is that based

Operating state signal to radio, the detector unit may also be integrally formed with the receiving unit. Local radio means in the present case in particular that by means of a radio link a communication range in a range of a few meters, for example in a range of about 0.3 m to about 25 m, preferably in a range of about 0.5 m to about 10 m, particularly preferred in a range of about 1 m to about 5 m can be achieved.

Due to the arrangement of the transmitting device or the beacon, the invention allows an existing energy and / or communication interface of a

Light installation or the lighting device or a lighting means of the lighting device for the

To use energy supply one or more of the transmitting devices or beacons. This can be on the secondary side and / or primary side, for example

Communication interfaces of an electronic

Ballast (ECG) of the lighting device as well

Communication and / or combined energy and

Include communication interfaces.

One possibility in which a separate energy converter for the transmitting device or the beacon can be saved is also an electrical connection of

Transmitting device or the beacon in parallel to a light source, in particular to a light emitting diode unit or a group of light emitting diodes or possibly a light emitting diode carrier module and / or

like that. It is further proposed that the transmitting device an energy storage and the detector unit a

Supply voltage sensor for detecting a

Have supply voltage of the transmitting device and the transmitting device is adapted to be supplied at least partially via the lighting device with electrical energy for their intended operation, wherein the detector unit is formed, as the operating state signal, the supply of the transmitting device with electrical energy to detect from the energy store. This embodiment allows the operating state signal

sender device side respectively

to be able to detect internally the light fixture side. The external unit is formed in this embodiment by an external control, by means of which the lighting device can be controlled with regard to their intended operation. Namely, if the lighting device is disabled in terms of their light output, this can be detected by the fact that in this operating state of the lighting device, the transmitting device is supplied with electrical energy from its associated energy storage. As a rule, this can be detected by means of the supply voltage sensor, the signal of which can then be used as an operating state signal in order to determine the operating state of the transmitting device,

in particular their receiving unit to be able to control in the desired manner. It therefore does not need a separate external unit in this embodiment. A further development provides that the activated

Operating state only for a given period of time

is taken. This can be achieved that a required additional energy consumption is limited. In addition, an improved security can be achieved because namely the activated operating state does not need to be maintained indefinitely. As soon as the predetermined period has expired, the

for example, by taking the activated

Operating state is started, the receiving unit can be automated again transferred to the deactivated operating state. Only during the activated

Operating state is a communication with the

Sending device to the effect that data to the

Transmitting device, in particular the receiving unit, can be transmitted. The activated operating state of the receiving unit can therefore not remain permanently activated inadvertently in this embodiment. The predetermined period may, for example, a few minutes, in particular about 10 minutes, preferably 15 minutes, or

the same amount.

It is further proposed that the transmitting device

at least partially via the lighting device with

electrical energy for their intended operation, preferably independent of a normal operation of the lighting device, is supplied. This embodiment has the advantage that a substantially continuous, preferably uninterruptible, power supply for the transmitting device or the beacon can be provided. Especially for the inventive use, this is of particular advantage, because depending on the design of the

Lighting system can be provided that a

Configurability of the transmitting device to be made at repeated predetermined times. Since the activatability of the receiving unit depends on the function of the transmitting device or the beacon, a disturbance in the transmitting device or the beacon would also be a fault with regard to the latter

Configurability result. By the

Power supply via the lighting device can reduce this problem. It can be considered that the lighting device usually has a

Power supply terminal has, preferably

permanently provided for the intended operation. This can also be a communication port of a

Communication network to which the lighting device is connected.

In addition, it is suggested that the

Operating state signal, the receiving unit for one or more fixed time windows activated. This can be achieved that the operating state signal the

Receiver unit does not need to activate immediately. For example, there may be a predetermined time delay of

Example, a few seconds or minutes or the like may be provided to the controller, for example, in a to bring predetermined position, so that the control unit in communication with the transmitting device

or their receiving unit can occur. This embodiment proves to be particularly advantageous if the activated operating state of the receiving unit is limited in time. For example, it can be provided that the time window is opened with a delay of one or more minutes and for example 10

Minutes lasts. Should be in this period a

Configuration of the transmitting device or the beacon can not be completed, a further period can be attached accordingly. This may for example be separated from the previous period by a deactivated operating state. For example, it can be provided that the two successive time windows in which the receiving unit is in the activated operating state are separated from one another by a period of, for example, 30 seconds in the deactivated state. As a result, additional security can be achieved. It may also be provided that the successive

Time windows last for different lengths of time by adding to

Example, each additional time window shorter than that

previous time window is. Furthermore, it is proposed that the receiving unit at least a predetermined time for a

preset detection period is automatically activated by the receiving unit via radio only the

Operating status signal is received. Thus, it may be provided that at successive times, which may be, for example, 10 minutes or longer,

Acquisition periods of, for example, 30 seconds or

be activated, in which by radio from the

Controller the operating state signal to the

Transmitter can be transmitted. The radio unit receives the signal emitted by the control unit and

determines whether it is an operating state signal. If they are other signals, they will not

considered. Only if sender device side one

corresponding operating state signal is detected, by means of this operating state signal, the corresponding

Control of the receiving unit for the execution of

Configurations are activated. Of course, the detection period may also vary as needed, for example

15 seconds or even 45 seconds or even several minutes. Corresponding variations can also with respect to the

be given predetermined time. The default

Time may for example also be dependent on a local time, a date and / or the like, so that the receiving unit is activated, for example, on a certain day at a certain time of the detection period or the like. For example, it may also be provided that the time is only once an hour or once a day.

The operating state signal may preferably be from a

Luminaire control signal for a luminaire operating state of the lighting device dependent. For example, can

be provided that a certain operating state of the lighting device at the same time also the operating state signal for the transmitting device or their

Receiving unit provides. It may be at the

Operating state also by a predetermined sequence of

act different operating states of the lighting device. It proves to be particularly advantageous if as

Operating state signal is used a switching pattern for the operation of the lighting device. Activation of the

Receiving unit can be done for example via an activation pattern or signal pattern, which the

Activation or deactivation of the

Lighting device as a whole. For example, by operating a light switch, a predetermined switching pattern can be initiated, for example by successive and turn off to generate the desired operating condition signal. As a basis for the detector unit, for example, different voltage levels between an external and an internal power supply can be used here.

It proves to be particularly advantageous if the

Operating state signal uses light, an electric field and / or a magnetic field as a medium. It can be achieved in a simple manner wireless provision of the operating state signal. For example, it is possible to use a light-based operating state signal, whereby an optical activation of the receiving unit can be achieved. For the optical activation, the transmitting device or its detector unit preferably has a light receiver, for example a photodetector or the like, by means of which a corresponding one

Light signal can be detected. The light receiver can then send a corresponding electrical signal to

Activation of the desired operating state. An activation of the respective desired operating state or even of a switching process can be achieved, for example, via an intensity of the received

Light signal or by means of specially modulated light in the visible or in another area, in particular in the infrared range, take place. For example, it is possible to generate a photo flash by means of a smartphone, which can serve as a light signal. In addition, a magnetic field sensor or a sensor for sensing an electric field of the detector unit can be used, by means of which a magnetic field and / or an electric field can be detected in a, preferably immediate, environment. If, for example, a magnetic object or else an electrically charged object is brought into the vicinity of the corresponding sensor, a corresponding one can be generated by means of the sensor

Field strength change detected and a corresponding signal as Operating state signal can be provided. The corresponding sensor is also preferably in the

Transmitter or its detector unit integrated.

An advantageous development suggests that the

Operating state signal uses sound as a medium. Accordingly, the detector unit comprises an acoustic sensor, for example a microphone or the like. Particularly advantageous is the design in conjunction with the use of ultrasound. Activation of a desired

Operating state or a switching operation of the operating conditions can in this case for example via a

Intensity of a received sound event, for example by a predefined frequency pattern and / or the like, or by a specially modulated acoustic trigger signal. This may be a specific acoustic signal which is contained or encoded, for example, in an acoustic work, such as a piece of music or the like, and in particular can be used for background sounding of the service area or can also be played by the external unit , Furthermore, it proves to be advantageous if the

Operating state signal is provided by a supply voltage sensor for detecting a supply voltage of the transmitting device. The supply voltage is one

electrical voltage that is at an electrical

Power supply of the transmitting device is provided. In this way it is possible by influencing the

Supply voltage of the transmitting device to generate the corresponding operating state signal. Of the

Supply voltage sensor can also by the

Detector unit includes. So it is possible, for example, in a predetermined manner to the supply voltage of

Acting transmitting device to thereby the

Operating state signal in the desired manner to trigger can. This is particularly suitable for the embodiment in which the transmitting device has its own additional

Energy supply with an energy storage includes. Thus, activating the respective operating state

or switching between the operating states by turning off a power supply done.

For example, a different voltage level can be detected, for example by the transmitting device itself, in particular its supply voltage sensor. Lies

For example, in an external power supply by means of the lighting device, a voltage level of about 3 V, while at a power supply through the own energy storage, a voltage level of, for example, 2.8 V is applied, this can be detected by the supply voltage sensor and a corresponding operating state signal are issued. As a result, a change of

Operating state of the transmitting device or its receiving device are initiated, for example, a

Change from a connectable mode to a non-connectable mode or the like. It is also conceivable, for example, the case that the light installation is turned off in the service area for the configuration of the transmitting device.

It also proves advantageous if the receiving unit of the transmitting device in the activated operating state with a central information processing in

Communication connection is and the transmitting device automated by the central information processing

is configured. This embodiment uses the invention to easily make the configuration of the transmitting device or the beacon. Because the activated operating state of the receiving unit can be adopted in accordance with the invention, it is possible to have a corresponding configuration of the transmitting device

or the beacon, as described above, make. Preferably, the receiving unit of the transmitting device in the activated operating state is in communication communication with the external unit via a radio link and the transmitting device is configured by the external unit. The receiving unit receives data corresponding to the configuration of the external unit

Serving device can serve. In addition, these data can of course also serve the configuration of the lighting device as a whole.

Infrastructural device 22 in communication connection, can be exchanged on the data concerning a normal operation of the lighting device 12 as well as data relating to the other lighting devices 20. The

Lighting device 12, and in particular their beacon 16, therefore also serve as a means for forwarding corresponding data from the infrastructure device 22 to the lighting devices 20 and vice versa, for example in the manner of a network node.

Beacons 16 for the aforementioned user potentials a location or orientation system. In particular, it is possible to accurately locate the self

Communication terminal 34, whereby services are available, such as navigation or the

Provision of site-specific information.

One aspect of beacon technology is the ability to configure typical parameters, such as signal strength and / or transmit interval, of the beacon 16 radio signal 18. With different configurations, different application scenarios can be individually supported. Will, for example, a high quality of service,

For example, a precise localization at short intervals, desired, as required in particular for indoor navigation, preferably very short

Send intervals be configured.

Fig. 2 shows a first embodiment for a

Lighting device 12 of the illumination system 10 according to the invention. The lighting device 12 is shown as an example only as the only light in Fig. 2. The

Lighting system 10 may of course also include other lighting devices 12, which are preferably constructed similar. The lighting device 12 includes the beacon 16 as a transmitting device and not further shown

Illuminant, as has already been explained with reference to FIG. 1. The beacon 16 is right on the

Luminaire 12 and its lighting means arranged. The beacon 16 is configured to wirelessly transmit a radio signal 18 with identification data specific for the beacon 16. The beacon 16 includes a

Receiving unit, which is not shown in FIG. 2 and which is adapted to receive radio signals of an external controller 80 as an external unit, such as a communication terminal 34, which may be, for example, a smart phone, a laptop or the like.

The receiving unit is formed depending on one

Operating state signal of the external control device 80, which may also be a smart phone here to take a respective of at least two operating states, namely an activated operating state in which the receiving unit is ready to receive data from a data source, which in the present case also the external control unit 80th may be to receive and a disabled operating state. In the deactivated operating state, the receiving unit does not receive any data.

The lighting device 12 is based essentially on the lighting device 12, as has already been explained with reference to FIG. 1, which is why reference is made to the description of FIG. 1 with respect to the further details.

In the present case, the beacon 16 includes a separately arranged detector unit 84, which in the present case in a housing of the

Lighting device 12 immediately adjacent to one of their

Light source is arranged. The detector unit 84 is for detecting the operation state signal and controlling the operation state of the reception unit depending on detected operating state signal. For this purpose, the detector unit 84 is in communication with the beacon 16 via a communication link 86. The lighting device 12 further comprises a

Energy interface 36, via which it is connected to the light control, not shown in Fig. 2. The

Energy interface 36 is over a

Power transmission channel 90 to an electronic

Ballast 46 connected, which in Fig. 2, not shown illuminants in a predeterminable manner

In the present case, the lighting device 12 further comprises an accumulator 38, which serves to supplement the power supply of the lighting device 12, and in particular its controlling units. The beacon 16 includes in a known manner in addition to the transmitting and receiving units, not shown, the control unit 28, which via a power transmission channel 64 to a

Power interface 52 of the beacon 16 is connected, in turn, via a power transmission channel 92 to the power interface 36 of the lighting device 12th

connected.

The energy interface 36 of the lighting device 12 is connected via a not further designated energy transmission channel to a mains supply 58, which serves to supply the lighting device 12 with electrical energy from a public power grid.

In addition, the communication terminal 34 may be connected to a router 40 in FIG. 4 through a communication link 42 configured as a local radio link

Communication connection stand. The router 40 is connected to a via a wired communication link 44 Infrastructure device 22 connected, the present provides access to the Internet or to a central service server. The detector unit 84 detects by means of a suitable sensor unit an operating state signal 82, which is output by means of the external control device 80. As soon as a corresponding operating state signal by means of

Detector unit 84 is detected, takes place

corresponding communication via the communication link 86 to the beacon 16, the receiving unit then in

specifiable manner activated so that by means of

Communication terminal 34, a corresponding configuration of the beacon 16 can be made.

In the present embodiment, it is provided that the detector unit 84 is designed to detect a flash of light, a sound event or a radio signal as the operating state signal. The detector unit 84 has suitable sensor units for this purpose. The detector unit 84 then transmits a corresponding electrical signal via the

Communication link 86, which in this case a

In this way, a configuration of the beacon 16 can be made, the receiving unit in his

Delivery state or in the ordinary

intended operation is deactivated. This can avoid unwanted or accidental configuration changes.

Fig. 3 shows a further embodiment for a

Lighting device 12 according to the invention. This embodiment is based on the embodiment, as has already been explained with reference to the preceding embodiments and figures, which is why complementary to the relevant

References. From the embodiment of FIG. 2, the embodiment differs according to FIG. 3 in that the

Operating state signal within the lighting device 12, and here in particular by the beacon 16 itself, is determined. As the operating state signal is at this

Embodiment switching on the electronic

Ballast 46 by means of a detector unit, not shown, which has a suitable

Supply voltage sensor comprises, detected. The

electronic ballast 46 is over a

Power transmission channel 48 connected to a light-emitting diode module 50 as a light source to supply this in a predeterminable manner with electrical energy.

For this reason, this embodiment also contains no accumulator such as the accumulator 38 in Fig. 2. As soon as the detector unit switching on the electronic

Ballast 46 detected as the operating state signal is in the present embodiment for a given

Time span, which in the present case is about 10 minutes, the

Receiving unit of the beacon 16 is activated for the purpose of receiving data by means of radio signals. If the time has elapsed after switching on, the receiving unit

automatically deactivated again.

The embodiment according to FIG. 3 can furthermore be supplemented by the fact that the receiving unit can also be activated for the given period of time at predetermined time intervals. The predetermined time intervals can for

Example one or two hours, but also a day or a week and combinations thereof.

Fig. 4 shows a further embodiment, which on the

Embodiment according to FIG. 3 is based, which is why reference is additionally made to the relevant explanations. In the

Embodiment of FIG. 4 is - as in the embodiment of FIG. 2 - an accumulator 38 as energy storage provided, which is connected via a power transmission channel 96 to the power interface 52 of the beacon 16.

In this concept, switching of the

Operating state of the receiving unit when switching from one type of power supply to another type of power supply. In the present case, the detector unit, which is not shown in FIG. 4 and is part of the beacon 16, detects via which energy transmission channel the beacon 16 is supplied with electrical energy, namely whether the beacon 16 electrical energy from the electronic ballast 46 via the energy transmission channel 92 or electrical energy from the accumulator 38 via the

Energy transfer channel 96 refers.

The detector unit of the beacon 16 can do this

Determine that the respective voltage levels

slightly different from each other. In the present case is at a power supply from the accumulator 38 to the

Power supply provided slightly lower voltage than when the beacon 16 from

electronic ballast 46 is supplied with electrical energy. The detector unit comprises in this respect a supply voltage sensor which can determine the corresponding voltage differences. The operating state signal obtained therefrom is then used to control the

Operating state of the receiving unit of the beacon 16 used. In this way, by the beacon 16 itself a

appropriate adjustment of the operating condition of the

Receiving unit are made. For example, in the case of a power supply via the electronic ballast 46, a voltage of about 3 V is applied, whereas in the case of a

Power supply through the accumulator 38 is applied a voltage of about 2.8 V, this can be done by means of

Supply voltage sensor can be detected and a

corresponding operating state signal can be provided. The other functional processes essentially correspond to those as already explained above. Fig. 5 shows a further embodiment of a lighting device 12 according to the invention, which on the

Embodiment is based on FIG. 4, which is why reference is additionally made to the relevant embodiments. Again, the accumulator 38 is exclusively on the

Power transmission channel 96 connected to the power interface 52 of the beacon 16. It thus serves exclusively for supplying energy to the beacon 16. The energy interface 52 of the beacon 16 is also present over the

Power transmission channel 92 to the electronic

Ballast 46 connected.

In contrast to the embodiment according to FIG. 4, it is provided here that the electronic ballast 46 is furthermore connected to a light switch 98 via an unspecified communication connection.

The activation of a respective operating state, here the activated operating state of the receiving unit of the beacon 16, via an activation pattern or a

Signal pattern, which can be generated by means of the light switch 98. The switching pattern, for example a sequence of switching on, off, on, off, can by means of the detector unit - as already for

Embodiment of FIG. 4 explained - are detected, by means of the supply voltage sensor. The switching pattern generated by means of the light switch 98 is equally transmitted via the electronic ballast 46 to the power transmission channel 92, so that the

Detector unit of the beacon 16 can detect the corresponding switching pattern as an operating condition signal and a

can cause appropriate control of the receiving unit. In the present case, it is provided that upon detection of the

Operating state signal, the receiving unit for a

predetermined period of time is activated. Overall, for example, the following mechanisms for switching between the activated and deactivated operating state of the receiving unit can be used. In an optical detection by means of an optical sensor, for example, the light intensity can be used, for example, by using a flash of the external control device, which is detected by the optical sensor. In addition, it is possible to modulate the light intensity, for example, comparable to an infrared remote control, in particular in the manner of a pulsed

Light signal, for which purpose an infrared sensor chip and a corresponding data processing can be provided in the detector unit.

With regard to an acoustic operating state signal, provision can also be made here for the intensity to be used for a corresponding control of the operating states

to be able to make. For example, a volume can be used, which by means of a microphone of the

Detector unit can be detected. In addition, of course, here also the possibility to provide a corresponding acoustic modulation, for example by a corresponding coding of information is made, which can be detected and / or decoded by the detector unit accordingly. The operating state signal may, for example, also be embedded in background noise, for example background music. A further possibility of controlling the operating states of the receiving unit consists in using a magnetic operating state signal which can be detected, for example, by means of a Hall sensor of the detector unit.

For example, the magnetic field strength can be detected in a closer, in particular immediate, environment of the beacon 16. This can be done for example by means of a

Configuration bar with an integrated magnet respectively. Accordingly, a control by means of an electric field can be provided.

In addition, it is possible to use a radio-based operating state signal, for example in one

Frequency range of about 800 MHz, in particular using a mobile network such as LTE or

like. In addition, a WLAN operating state signal can also be used, for which purpose the beacon 16, for example, a WLAN unit as transmitting and

Receiving unit may have. For the purpose of

Operating state signal may, for example, a corresponding signal via a separately selected channel

to be provided. Furthermore, it is possible to use a near-field communication (NFC) sensor in order to provide a corresponding basis on the basis of near-field communication

Be able to provide operating state signal. It is also possible, in addition to the previously mentioned BLE interface to use a further Bluetooth interface, which is preferably exclusively intended to be used for configuration purposes. Finally, there is also the possibility that the beacon 16 additionally has a ZigBee module, so that a corresponding

suitable signal can be detected as the operating state signal.

The aforementioned sensors and units for detecting the respective operating state signal are preferable

Part of the detector unit and can in this

be integrated. In addition, of course, if necessary, the possibility to arrange the corresponding unit away from the detector unit. It may, for example, communicate with it via a wired communication link. Preferably, the

However, each unit in or on the
