description

The invention relates generally to lighting devices for interiors. In particular, the invention relates to lighting devices with variable illumination parameters, such as color and brightness and very high

Quality requirement for photometric parameters, with which a coordinated or consistent, reproducible lighting according to requirements can be ensured.

From the German patent application DE 10 2013 112 906 Al a controlled color light source is known comprising a lighting device which has at least two light-emitting diodes, wherein the color and / or brightness representation is controlled by a sensor. Several such light sources, each with identical exit optics can be connected to a lighting device. The exit optics comprises an optical waveguide in which the light is coupled out by means of a scattering layer applied laterally on the optical waveguide, which can be designed, for example, as a rod made of plastic or glass. The color light source has control electronics with which the brightness of the semiconductor light-emitting elements can be adjusted, and a light sensor which receives light emerging laterally from the light guide. The sensor signals are over an integration time interval

accumulates and the accumulated signals compared with a desired value or target range and the brightness of the light emitting elements in dependence on the difference of the sensor signals to the desired value or target range changed. Besides, that will

Integration time interval depending on the distance of the sensor signal to the setpoint or setpoint range or adjusted depending on a change in the setpoint.

WO 2012/146719 Al describes an operating device for a light source with an adapter, which is designed as an external device part, preferably as a plug, and is configurable by the supply of control signals. On the external device part there are connection elements for the power supply of the operating device. The external device part is connected to the operating device by power conducting means and / or signal conducting means.

From US 2016/0312986 Al a smart lighting fixture is known which can perform electrical measurements or a control of the lighting level. The lighting fixture comprises a lighting control unit which controls the amount of light emitted. In addition, the brightness can be controlled by an external device. A control of a vehicle lighting system based on transmitted from an external source to a microcontroller

Illumination commands is also known from US 2011/0309746 A.

Lighting systems for cabin lighting of current aircraft are centrally addressed, controlled, controlled and / or regulated as well as and / or configured via complex cabin management systems (CMS) as a control unit (SE). The configuration of one or more illumination devices takes place via the CMS itself or by means of auxiliary means for configuration, for example, a programming device successively or else in parallel, or more or less simultaneously.

The lighting devices are connected to the electrical system for electrical supply and connected via a so-called BUS system (eg RS 485) with the CMS, via which the digital control, data transmission and / or communication between the CMS and the lighting devices is realized. This requires a special wiring (eg. So-called "DaisyChain" - wiring) of the individual lighting device or the

Lighting devices with each other. In order to be able to address individual illumination devices or groups of illumination devices in a targeted and secure manner in such a system, each illumination device must be assigned a unique address.

In particular, light-emitting diodes or other solid-based dampening solutions are increasingly being used as fountain solutions.

With these modern systems, versatile, variable and complex lighting functions can be flexibly implemented and thus contribute to the increased

The importance of the lighting, in particular with regard to the well-being of the passengers and also as a distinguishing feature of the airline bill. In particular variable, colored lighting, so-called mood light, as well as targeted

Illumination of objects and also safety-relevant elements of a

Aircraft cabin (accent light) is becoming increasingly important. Aspects of such a system are described in US2010109530A and US2010110706A.

Such or at least similar lighting options should therefore also be made available in aircraft that have already been in operation for years.

A conversion of these aircraft to BUS-based systems described above, which can take several days and large parts of

Cabin infrastructure is often for cost reasons, u.a. Limited expected service life of the aircraft, not economically useful. There

typically the entire cabin is affected by the conversion, often at least a few days of service life are needed.

Depending on the type and extent of such retrofitting, this can also entail complex certification processes, which is why aircraft owners, operators and suppliers are increasingly interested in leaving as many components of the existing infrastructure of the aircraft cabin unchanged or introduce as few new and standardized components as possible.

In the event that retrofitted systems are to be modified and / or components replaced or replaced, care is taken to ensure that the requirements for traceability and traceability can be easily implemented in accordance with the FUs regulations.

In such aircraft, usually simple control units are installed for lighting with few, limited lighting functions.

Their lighting devices are often connected only via individual control lines to the control unit and are powered by the electrical system. These lines are also not suitable or designed for data communication, which basically takes place in BUS-based systems.

As dampening solution usually come in the operating state white luminous

Moisture lamps are used, for which, also due to the design, often only the

Operating states On / Off and occasionally one or more brightness levels can be selected as lighting variants. Colors can only be realized through additional lighting, which is due to the cost of additional lighting Components, more maintenance and tracking and higher

Operating costs (weight) economically, at least in wide-bodied aircraft, hardly makes sense.

A variable configuration of the lighting systems, as in a current system is often not provided or possible.

In the case of the replacement of components of these lighting devices, it is often, especially when changing the bulbs, to undesirable deviation of the illumination parameters, which reflect as differences in color, color temperature and brightness of the light bulbs visible in the cabin. Differences in color and brightness can be caused especially by aging of the existing bulbs compared to, inter alia, in the course of maintenance or repair exchanged bulbs, or by manufacturing tolerances. There are also retrofittable lighting systems and / or facilities known, but which intervene in particular in the existing infrastructure of the aircraft cabin or even require their replacement, which is disadvantageous in terms of effort and costs.

Other systems in turn use the existing infrastructure for electrical supply and / or simple control, in which the

Operating devices of the lighting devices additional control modules are needed to, for example, a requested via a control unit lighting state to a lighting device, interpretable from this and implementable to transfer.

To modify the lighting parameters so far, if this is even provided, also often on external aids (eg.

Programming devices) can be resorted to one or more

To configure lighting equipment. Alternatively, one would also be

Configuration in the factory possible, but which would typically lead due to the large number of desired configurations for different customers to a large number of, often kept, corresponding components and / or assemblies (part numbers or Partnummem), which logistics, warehousing and documentation for both the Makes customers as well as for the manufacturing plant significantly more complex.

A configuration with external means requires specialized personnel and special tools on site during installation or repair operation and is in accordance with the Extensive documentation of existing aviation standards, especially if a plurality of lighting devices of a lighting system or a group of lighting devices of a lighting system must be individually, ie each configured for itself, since unlike BUS systems, a discrete

Addressing is hardly possible.

Likewise, this does not ensure that all installed, retrofitted, affected by an exchange and or by a modification

Lighting equipment Compliance with requirements and requirements for consistent lighting.

Configuration and compliance with consistent lighting can be particularly disadvantageous if elements of the

Lighting devices, such as bulbs, light distributor and / or operating device must be replaced and / or modified

Lighting parameters (for example, other color combinations) to be implemented. For this purpose, the configuration state would have to be saved first of all whenever an element changes, and then finally retransmitted. Alternatively, could

According to preconfigured lighting devices are kept. This, in turn, is for both the user and the supplier

Lighting equipment expensive and therefore not economically useful.

In general, in previous luminaires with intelligent

Operating devices configuration data stored in a memory and can not be changed from the outside without further aids. When replacing the luminaire, the respective correct data record for the intended installation location must then be transferred to the luminaire prior to installation, or different preconfigured luminaires must be provided.

Transmission of operating parameters from a central device, such as a central controller, is also often not possible if a corresponding suitable communication channel is not present.

The invention is therefore based on the object to simplify the configuration of parameter-controlled lights, especially in view of the above-mentioned problems in the maintenance and retrofitting or conversion of existing systems. This object is solved by the subject of the claims. According to the invention, a lighting installation for lighting, especially of vehicles and interiors, is provided. The lighting installation here comprises at least one lighting device, wherein the at least one

Lighting device an operating device for controlling the light output of the

Lighting device, and having at least one light source, wherein the operating device is set, measured during operation with operating parameters

and to control the light output of the light source based on the comparison, wherein the illumination device further comprises a data storage module, in which operating parameters are stored in the form of data, wherein the data storage module is detachably connected to the operating device via an interface so that by separating the data storage module from the interface and connecting another data storage module with new operating parameters, these new operating parameters for controlling the

Lighting device can be supplied by means of its operating device. By controlling and correcting the lighting with the aid of the operating parameters, a coordinated lighting is created.

The invention represents a possibility of operating parameters for the

Store lighting device on an external medium that remains firmly in place. The data storage module can do this with means for connecting, for example, with a cable tie fixed to the structure or other stationary object, but in particular at the installation of the

Lighting device are connected to ensure that it is not removed when replacing the lighting device with. The connection between the lighting device / operating device can be direct or with a

Connecting cable, or even wirelessly done by radio. In an exchange, perhaps necessary due to a defect, the new, or replaced

Illuminating device without reprogramming or reconfiguration of existing operating parameters specified or intended for the installation site with external aids, directly reading out and using the existing configuration for the installation site. As a result, an additional or subsequent cabling is avoided. A preferred application of the lighting installation according to the invention is generally the interior lighting, in particular the cabin or

Interior lighting for a vehicle cabin, preferably the passenger cabin of an aircraft. Further uses include position lighting of aircraft, ships and / or trains, as well as lane lighting, fighter patrol flags or ferry terminals.

Particularly advantageous when using the invention as a lighting installation in an aircraft cabin is that the requirements for traceability and documentation obligations in the Fuftfahrwesesen (eg to CFR14, FAR25 US Federal Aviation Administration (FAA) or EU Regulation No. 748, CS-25 of European Aviation Safety Agency (EASA)). This is primarily due to the fact that a given configuration is present in the data storage module and preferably no modification of the existing infrastructure during the retrofitting or retrofitting of existing illumination devices with the data storage modules has to be undertaken. It is neither necessary to adapt the mechanical and / or electrical installation for the integration of the lighting system, nor to modify, for example, a central control, in order to be able to provide the possibility

To configure lighting installation by default. General is as

Embodiment of the method for operating the inventive

Lighting installation in terms of retrofitting provided that a

conventional illumination device without an operating device, which is configured to read operating parameters from a data storage module, by a

Lighting device according to the invention is replaced with a correspondingly configured operating device.

It is possible to have a lighting installation with only a single one

Provide lighting device. Particular advantages of the invention, however, arise in particular in more complex installations with several

Lighting equipment. Here, the separable data storage modules facilitate easy reconfiguration and integration of individual lighting devices.

Consistent lighting can be created for multiple lighting devices. As consistent lighting is understood in which in the operating state, the color and the brightness representation of several Lighting devices with each other and / or the at least one light source of a lighting device is coordinated.

In general, the invention also allows retrofitting

Lighting devices essentially without interference with an existing one

Infrastructure of control and supply units, while demanding lighting functions, or their modification can be implemented. The lighting functions according to the requirements also continue to be ensured in the case of the replacement of parts of the lighting device.

Furthermore, the illumination installation can be configured such that the illumination device has an optical sensor for detecting the emitted light intensity for comparison with the stored operating parameters. In the case of a detected by the operating device deviation of the output from the operating device from the sensor emitted light intensity of the stored values of the operating parameters, the emitted light intensity can be controlled by the operating device such that it corresponds to the stored value.

In an advantageous embodiment, the lighting installation can have a central control unit, which is connected to the lighting device for the purpose of transmitting control signals to the operating device.

In the case of using the lighting installation as cabin lighting in the interior of an aircraft, the central control unit of the central

Cabin management system (CMS = central cabin management system) formed, for example, is responsible for the centrally controlled dimming of the cabin lighting during takeoff and landing.

The light source of the lighting installation may comprise a semiconductor light source, preferably at least one light emitting diode. Particularly preferably, the semiconductor light source comprises a plurality of light emitting diodes which emit light of different color, so that by individual control of the light intensity of the individual light emitting diodes by the operating device not only the total light intensity,

or brightness, but also the color of the emitted light is adjustable. A preferred embodiment comprises in each case at least one red, green and blue light-emitting diode, so that white light can also be generated by mixing the light of these light sources. According to a further development, at least one is additionally white illuminated LED provided. In this way, the color temperature of the light can be adjusted very sensitively with the aid of the colored light-emitting diodes.

The interface of the lighting installation can either be a

Plug connection or a wireless connection and / or an optical connection. The connector can be a wired and / or optical

Create data connection.

In the case of a connector, the interface may be from a serial bus such as Inter-Integrated Circuit (I ² C), RS485 Bus, Universal Serial Bus (USB), Controlled Area Network (CAN), Local Interconnect Network (LIN) or Serial Peripheral Interface Bus (SPI) are formed. If the interface is implemented as a wireless connection, Near Field Communication (NFC), WiFi, Radio Frequency Identification (RFID) and BT (Bluetooth) may be considered. A special case of the wireless connection is an optical-wireless connection such as IR or QR / bar code scan.

The operating parameters generally dictate how the

Lighting device to be operated. Thus, a certain predetermined Farbort- and brightness value, directly after switching on or at a

defined event to be emitted should be defined as an operating parameter. The operating parameters can also be a temporal color and / or

Include brightness gradient. Accordingly, the operating parameters may include color change or color scenario procedures.

Likewise can be deposited as operating parameters, such as the

Lighting device should respond, if there is a fault. For example, after a fault, both the switching off and the lighting in a specific color or signal sequence could be defined.

In general, limit values can also be provided as operating parameters by means of which the control of brightness, color or of input and output

Switching operations, as well as, for example, a fail-safe operating mode takes place. To give an example, a limit for the ambient brightness can be provided, by means of which the switching on of the light source (s) of the illumination device takes place. io

If you want to set new color presets, only the

Data storage modules of lighting devices are exchanged. Conversely, lighting devices replaced, data storage modules can remain at the installation and connected to the new lighting device, so that the new lighting device fits directly into a given environment due to the already existing for this operating parameters. The im

Data storage module of the illumination installation according to the invention stored operating parameters may generally include one or more of the following parameters:

- lighting parameters,

- control, regulation and / or monitoring parameters,

- electrical parameters,

- temporal parameters,

- location and installation information,

- Lighting equipment classifications / selectors

- device parameters or identification parameters of lighting installation,

Lighting device or light source,

- Identification or compatibility parameter of the data storage module.

Photometric parameters may be, among other things, the luminous flux to be delivered, or the brightness, as well as the light color.

Control, regulation and / or monitoring parameters may include the permissible values or maximum values for operating temperature, operating current and operating voltage. Also, the control accuracy, and / or control speed of the lighting parameters as

Control parameters to be stored. The control accuracy can be as

Step width of the respective parameters be deposited.

Temporal parameters may also be time information about the inspection or maintenance of the lighting device, such as one or more time intervals. Special time parameters can be times or processes to achieve

Dimming conditions, Larbwechseln, Lichtstärkewechseln, more general of

Be lighting scenarios. Also, the aging of the lamps or their change in

photometric or electrical properties over time as a parameter or parameter set be deposited. Such parameters can be classified as both temporal and photometric parameters.

The permissible color deviation, for example in the form of a McAdams ellipse as a stored parameter, can be understood both as a photometric and as a control or control parameter.

In particular, electrical parameters can be current / voltage specifications, if appropriate also for different lighting scenarios.

As location and installation information, for example, come

Aircraft type, the installation location in the aircraft (for example, in which class, in the ground, in the wall, in the ceiling, ...) into consideration. It can also be deposited as installation information with which other lighting devices that concerned

Lighting device should be coordinated or collaborate.

Device parameters or identification parameters of the lighting installation, lighting device or light source may, inter alia, be parameters which allow the determination as to whether the light source and the lighting device are compatible with one another. Such parameters then also provide identification or

Compatibility parameter. Thus, an identification number can indicate whether the data storage module can be operated on the illumination device or not. Identification parameters may also include part numbers or part numbers. With these can check the compatibility of replaced components or adjust the operation of the lighting device by using the applicable

Part number selected by the lighting device lighting parameters are selected.

Data on the scope of use of included scenarios can be found next to the

Information in which class (Business Class, Economy etc.) the respective

Lighting scenario or which lighting parameters are to be applied.

In general, this information may be different

Be considered equipment in the areas to be illuminated. Thus, in a region equipped with darker materials, a relatively brighter illumination could be provided and / or taken into account in the associated illumination scenarios. Type selection parameters can be selectors for scenarios generated by

Lighting classes, such as contour lighting, ambient lighting, general lighting depend. These selectors can determine how light sources should behave, which typically can not represent a scenario, for example because they are monochrome.

Furthermore, the operating parameters can link between available inputs and outputs, the above parameters, independent light sources and

Auxiliary devices (such as, for example, light switches, presence detectors, etc.) include in order to define the desired global interaction of multiple lighting devices

In the context of the invention, a method for operating the

lighting installation according to the invention, in which at a

Illumination device of the lighting installation at the installation site of the

Lighting device, a data storage module via an interface with an operating device of the lighting device for controlling the light output of the

Lighting device is connected, wherein in the data storage module

Operating parameters for the lighting device are stored, which are read by the operating device, and wherein the operating device measures operating parameters and compares with stored Betriebssparametem, and the light output of the

Controlling light source based on the comparison. The read-out operating parameters can, in particular after the readout by the operating device from the data storage module stored in a memory in the lighting device and from the

Memory are then read out for processing during operation of the lighting device by the operating device. In this way, the illumination device can function independently of the presence of the data storage module, or independently of an existing connection of the illumination device to the data storage module. In a further development of this embodiment of the invention, therefore, the at least one illumination device is set up to carry out or continue to emit light with the operating parameters of the data storage module independently of the connection of the data storage module with the interface. According to a further aspect of this embodiment of the invention, therefore, the operating parameters in addition to storage in the memory of Filed lighting device. The internal memory of the illumination device is preferably also, like the memory of the data storage module, a permanent memory, such as a flash memory. The operating parameters are thus permanently stored twice, namely once in the data storage module and once in the internal memory of the illumination device. Since the internal memory is permanent or permanent, the content of the memory is in particular after switching on, or commissioning of the lighting device available, regardless of whether the data storage module to the

Lighting device is connected. The illumination device does not need to read the data storage module again during commissioning. However, it may be provided that a reading-out test is part of the commissioning routine in order to check for the presence of new operating parameters.

It is still not excluded that when saving the

Operating parameters, a data processing takes place, so that the operating parameters as data does not necessarily have to be identical, but only the same

Information include. So it would be conceivable that the operating parameters in

Data storage module for easy editing as a string variable or text are stored and the storage in the internal memory in corresponding

Hexadecimal numbers are converted.

In the following, the invention will be described in more detail with reference to the accompanying drawings, wherein like reference numerals refer to the same

Designate components.

lighting installation according to the invention, installed in a vehicle,

Illuminators with data storage modules to provide operating parameters.

4 shows an interior with a lighting installation 1.

Fig. 1 shows, installed for example in a vehicle 13, a

Illumination installation according to the invention 1. As shown, the illumination installation comprises at least one, but as a rule, a plurality of illumination devices 3.

The vehicle 13 may have a central control unit 2, which is connected via at least one control line 12 and a supply line 10 to a control gear 5 of the lighting installation 1. The supply line 10 serves the

Voltage supply of the operating device 5 and thus the lighting installation 1. The control lines 12 and the supply line 10 can also be combined, so that the operating device 5 receives both control signals and voltage over the same line.

If the vehicle 13 is an aircraft, the central control unit 2 may be the control unit of the Central Cabin Management System CMS.

The operating device 5 comprises one or more interfaces 11, via each of which a data storage module 9 is connected.

The interface 11 can be realized by means of a wire or plug connection. For example, I ² C, RS485, USB, CAN, LIN or SPI come into consideration for this embodiment. Alternatively, the interface 11 may be wireless. If the wireless communication via the interface 11 is electromagnetic, for example WIFI, BT RFID and NFC can be used. In the case of wireless optical communication between data storage module 9 and

Operating device 5 via the interface 11, for example, infrared (IR) or QR / bar code scan are used.

The data storage module 9 contains operating parameters for the light source 7. The data storage module 9, if the interface 11 is designed as a plug-in connection, be a dongle or a USB stick. The operating parameters are, without limitation to the data mentioned, photometric parameters, Control, regulation and / or monitoring parameters, electrical parameters, time parameters, location and installation information, and device parameters or identification parameters of lighting installation 1, lighting device 3 or light source 7, identification or compatibility parameters of the data storage module 5.

In addition to the operating device 5, the lighting installation 1 comprises a

Light source 7, which in turn comprises one or more light sources 6 and a light distributor 8. Light source 7 and operating device 5 together form the

Lighting device 3 as part of the lighting installation 1.

As lighting means 6 are according to a particularly preferred

Embodiment used several LEDs. These give light

different color. The color of the light emitted by the light source 7 then represents a mixture of the colors of the individual light-emitting diodes. If the light-emitting diodes are activated separately from the operating device, a specific color impression can be achieved by adjusting the individual light intensities of the light-emitting diodes

be caused. As colors in the sense indicated above, not pure spectral colors alone are considered. Rather, the colors may include, for example, different white tones that correspond to different color temperatures. Also, various white shades can be colored by mixing colored, e.g. red green and blue light emitting diodes are mixed.

Furthermore, the lighting installation 1, as a common part of

Light source 7 and lighting device 5 have an optical sensor 4, which is the actual intensity of the light emitted from the light source 7 with a

predetermined, data storage module 9 stored and the

The setpoint is also stored in the data memory module 9 as an operating parameter, but is read by the operating device 5 from the data storage module 9 connected to the interface 11 and stored in the internal memory 17. Although the data storage module 9 remains on the illumination device 3, but the illumination device 3, regardless of the connection of the

Data storage module 9 are operated. This facilitates inter alia an update of the operating parameters or, conversely, an exchange of the illumination device 3. In this way, the operating parameters are stored twice, once in the

Data storage module 9 and also for the operation of the lighting device 3 in the memory 17 in the lighting device. In order for the data to be available irrespective of whether the data storage module 9 is connected, the memory 17 in the illumination device 3 is preferably designed as a permanent memory. This can therefore be, for example, a magnetic memory or a flash memory. The operating parameters are in this way even after an off and

Turning on the lighting device processed by the lighting device 3 when the data storage module 9 is missing, not connected, or is defective.

If no data is available from the data storage module 9 because, as stated, the data storage module is not present, defective or not connected, the illumination device according to one embodiment can also be set up to use a stored standard configuration and the operating parameters of this standard configuration to use for operation.

Although the illumination device 3 has an internal permanent memory as described above, such a standard configuration may be provided. This, among other things, when the lighting device 3 for the first time in operation

is taken and data of a data storage module 9 is not present, for example because a data storage module 9 is not present or connected.

In general, without being restricted to specific embodiments, it is thus provided in one embodiment that the illumination device 3 is set up to use a standard configuration for operation when the

Lighting device 3 can not rely on operating parameters of the data storage module 9. This recourse encompasses both the direct readout of the data storage module and the case where the operating parameters of the data storage module 9 have previously been stored in an internal memory as described above.

In the case of a deviation between the actual and target value of the spruce intensity, the delivered spruce intensity is regulated by the operating device 5 to the desired value. This control can also be designed as a color control, or a

Include color control. In this case, the spruce intensity becomes spectral, detected resolved by color and the light intensity of the light source controlled by the operating device accordingly changed spectrally. In this way, a previously defined color value can be precisely controlled. If a color value is part of the operating parameters of the data storage module 9, then if the data for a plurality of illumination devices of the illumination system 1

In this regard, the lighting fixtures are exactly matched to the same color values, even if they are not properly networked. This can be achieved using the operating parameters even if the light sources of different adjacent lighting devices are not identical. For example, in this case, the illumination device can be set up to select photometric parameters associated with a type selection parameter that are appropriate for the illuminant as operating parameters and, in this way, to emit, inter alia, a brightness and / or color suitable for adjacent illumination devices.

The data storage module 9 according to a preferred embodiment of the invention, without limiting to the example of FIG. 1, a housing 92 which surrounds the data memory 91 with the stored Betriebsparametem. This facilitates the handling of the data storage module 9, inter alia when the illumination device 3 is exchanged. In particular, the data storage module 9 can be connected to the illumination device 3 in a manner accessible from outside, wherein the data memory 92 nevertheless remains protected. In particular, such a data storage module can be designed as a USB stick or as a memory card, for example an SD memory card. The data storage module can also comprise an EEPROM that can be connected, for example, via a serial interface. According to a further embodiment, the data storage module 9 does not have to be connected to the illumination device during operation. Regardless of whether a connection exists or not, the data storage module but the illumination device 3 or at least clearly the lighting device can be assigned in the

Environment, or attached next to the lighting device.

For example, the data storage module may be attached to the lighting device by a cable tie or attached to a surrounding element such as a cable tie. Even with an arrangement of the data storage Module next to the lighting device, the data storage module but also be permanently connected with a cable connection to the lighting device.

Fig. 2 shows a schematic representation of the operation of a number of

Illumination Devices 3 of a Lighting Installation 1. As shown in Fig. 1, each of the lighting devices 3 comprises an operating device 5 with interface 11 and a light source 7. A number of lighting devices 3 are connected to each other and via an external bus 15, such as a RS 485 bus a central control unit 2 connected. The lighting devices 3 are located in a vehicle, not shown here, for example an aircraft. If the vehicle is an aircraft, the central control unit 2 is the cabin management system CMS.

Each illumination device 3 has a voltage supply unit 14. This can generally be part of an operating device 5 in particular.

The comprehensive control of the lighting devices 3 by the central control unit 2 requires a line network-like wiring inside the vehicle. The central control unit 2 is i.a. for the control of color scenarios for the

Light sources 7 of the lighting devices 3 responsible. such

Color scenarios can be, for example, that the light sources 7, depending on their position inside the vehicle, emit light of different larges.

Lig. 3 shows a schematic representation of the operation of a number of

Light sources 7 of a lighting installation according to the invention 1. In contrast to the arrangement shown in Lig. 2, each, in turn, each with a

Voltage supply unit 14 provided lighting device 3 coupled to a data storage module 5, for example in the form of a dongle or a USB stick.

In the data storage module 5 operating parameters for the operation of the respectively associated light source 7 are stored. These operating parameters may also include values for Larbscenarios and type selectors. Type selectors characterize the type of lighting device and / or components incorporated therein, thereby allowing, for example, the selection of alternative parameters depending on the type of lighting system

connected lamp type. The coupling of the data storage module 5 to the Illumination device 3 takes place via the interface 11 (FIG. 1) of the operating device 5 (FIG. When used in an aircraft can be used as an interface 11 an existing input / output interface.

The use of external data storage modules is compared to the use of the existing wiring of the vehicle in the form of an external bus, as shown in Fig. 2 advantageous because the configuration data for the individual light sources 7 are stored on an external data storage module, the fixed at respective place of use remains. In an exchange. e.g. due to a defect, the new light source directly uses the existing configuration stored in the data storage module. It is therefore no reprogramming or use of external tools necessary. Also, no connection to an external one

Control unit 2 required. This will be an additional or subsequent

Wiring superfluous. General is an inventive

Illumination installation 1, as also illustrated in the example of the Lig. 3, operated independently of the operable via the data storage module 9 operating parameters, whether a lighting devices 3 networking bus system, such as a bus system of a CMS is connected or even present. This is particularly advantageous because the invention in this way older cabin lighting can be retrofitted in aircraft in a simple manner. When retrofitting need only one or more lighting devices without operating device 5, which is adapted to read a data storage module 9, are replaced in each case by lighting devices according to the invention.

Without an external data storage module, configuration data must be stored in an internal memory of the light source 7. Those data can not be changed without further aids, such as a programmer, a firmware update, or a serial connection as shown in FIG. In the case of an exchange, the respective correct configuration status must be transferred to the new light source before installation. Alternatively, differently configured light sources 7 would have to be maintained. Both approaches are associated with high costs, which can be avoided by means of an external data storage module according to the invention. If the operator of the lighting installation 1 wishes, for example, a new color configuration, then it is sufficient to exchange the data storage modules 8 and to leave the lighting devices 3 in their respective places.

Even if the individual illumination devices of the exemplary embodiment illustrated in FIG. 2 are networked with one another and with a central control unit, illumination devices 3 can also be equipped with corresponding data storage modules 9 in this illumination installation. After a

Embodiment of the invention, therefore, a central control unit 2 is provided as part of the lighting installation, which is connected to the illumination device 3 for transmitting control signals to the operating device 5. The invention is particularly advantageous when only limited control functions are provided by means of the central control unit 2, for example because it is an older lighting installation. So such a control is often limited to functions such as on / off / dimmed. Here, the functions can be extended advantageously with the parameters stored separately and easily exchangeable via the data storage module 9. Thus, for example, the operating parameters may include a chronological course of brightness that is to be passed through by the illumination device 3 when a brightness change is transmitted via the central control device 2. Such a brightness change may be turning on, turning off, or changing the dimming level. In this way, brightness changes are less abruptly performed.

When using different types of lighting devices 3 each identically constructed data storage module 9 can be used to supply the various lighting devices 3 with type-specific parameter sets. For example, a general lighting by a pure

Ambient lighting supplements, both can be controlled via the existing signal lines from the central control device 2 and still indicate type-dependent different color scenarios. The operating device 5 selects from the stored in the data storage module 9 parameter sets the appropriate for the own luminaire type settings. The stored in the data storage module 9 and the operating device 5 provided operating parameters can one or more of the following

Information includes:

Control parameters which specify at which control by a central control unit 2 default illumination functions are realized,

Illumination parameters and functions, such as color, color temperature, color rendering indices, brightness, or dimming, color transitions,

Color scenarios, temporal parameters regarding the sequence of individual

Lighting functions

Device parameters complementary or substitute control, regulation parameters (including activation / deactivation of sensors or

Calibration values), monitoring parameters (such as temperature, current, voltage limits), location and installation information, and

Indentifikationsparameter associated lighting systems, control gear and / or the light source 7 and / or identification / compatibility parameters of the operating module,

a transformation function, in particular in the form of a transformation matrix for linking measured sensor values with current or voltage values of the lighting means to be set,

Control and regulation algorithms,

Identification or compatibility parameters,

Type selectors that allow the selection of alternative parameters depending on the connected lamp type.

Usually a transformation function, such as a

Transformation matrix component of the lighting device, or is deposited in the lighting device. In particular, such a transformation matrix can also be part of a standard configuration. In such a standard configuration, the lighting device accesses according to a

Embodiment back, in the event that no data storage module is connected with stored Betriebsparametem and / or no special operating parameters have been previously stored in an internal memory. Due to manufacturing and component tolerances, it can happen that

Despite their identical construction, lighting devices emit different light with otherwise identical settings or requirements. A significant point here are different so-called bins of light emitting diodes. This means that despite the same type LEDs with the same Betriebsparametem

can emit different wavelengths. To compensate for this, a transformation function, preferably a transformation matrix, can be determined and stored in the operating device. The transformation function specifies which color location and / or which brightness the LEDs actually emit at a specific color location / brightness preset. If appropriate, this can additionally be supported by built-in photometric sensors by measuring the color locus / brightness and optionally correcting it against it. If, as is the rule, several lighting devices are part of the lighting installation, the individual transformation functions are also generally different due to the specific characteristics of the light sources.

According to one embodiment of the invention, it is thus provided that in the operating device one adapted individually for the light source (s)

Transformation function is stored, which actual color locations and / or brightnesses of the light sources associated with predetermined values of the color location and / or brightness. The operating parameters contained in the data storage module 9 and preferably transmitted to the operating device 5 for operation of the illumination device and stored there can then in particular comprise the predetermined values of the color locus and / or the brightness. These are then from the

Operating device 5 by means of the transformation function translated into adjusted operating parameters, with which then the one or more light sources are controlled. The adjusted operating parameters can also be the direct current or voltage values for operating the light source (s) 7.

In the embodiment of the invention in which the data of the

Data storage module 9 one or more identification parameters of

Lighting installation, lighting device or light source included, the operating device of the lighting device 3 may be adapted to the

Identification parameters read and a compatibility check on the basis of Perform parameters. In particular, this compatibility check may include a test as to whether the identification parameter identifies the data of the data storage module as being compatible with the lighting device.

As explained above, the invention makes it possible to store configuration data for the illumination device 3 on an external data carrier, that is to say the data storage module 9. When replacing one of the lighting devices 3, which is required for example by a failure of the lighting device 3, the replaced lighting device 3 can read out and use the existing configuration for the installation directly by the previously with the previous

Lighting device 3 connected data storage module 9 is connected to the replaced lighting device 3. According to one embodiment of the invention, therefore, a method for operating a lighting installation 1 is provided, in which a lighting device 3 of the lighting installation 1 is replaced, the data storage module 9 separated from the interface of the lighting device 3 to be replaced, and the lighting device 3 to be replaced by a new Lighting device 3 replaced, and the data storage module 9 with the new lighting device 3 via the

Interface 11 is connected, whereupon the new lighting device 3 reads out the stored in the data storage module 9 operating parameters. Among other things, it is advantageous here that the new lighting device 3 to be exchanged does not even have to be identical. If, for example, the lighting devices 3 are replaced as part of a modernization, stand the new

Lighting devices 3 due to the acquired operating parameters, for example, the previously used colors of lighting, and

Lighting processes available. The new lighting equipment can therefore be seamlessly integrated into the lighting installation.

In the schematic representation of FIGS. 2 and 3, the

Lighting devices 3 shown similar. The lighting devices 3 can have different designs and / or allow types of lighting. Likewise, on an operating device 5 of a lighting device, a plurality of light sources of different characteristics with the respective elements for

Modification of the emitted radiation in the operating state be connected. This comes about when different elements of a

Aircraft cabin should emit the same color light and / or the same color, to be similarly illuminated. The lighting devices 3 may also differ in groups. Thus, in the example shown in FIG. 2 or FIG. 3, each row or even each column of the illumination devices 3, which are arranged here in matrix form, can each have a specific design. In general, therefore, several groups of different in their design

Lighting devices 3 may be present. In general, it makes sense if the operating parameters stored in the data storage modules 9 also differ at least in part corresponding to the group of illumination devices. In Fig. 3 is an example of a subdivision of

Lighting devices 3 in three groups 30, 31, 32 of

Lighting equipment made. Of course, the groups may also contain different numbers of illumination devices 3. In the example of FIG. 3, the group 30 contains eight lighting devices 3, the two further groups 31, 32 each contain four lighting devices 3. An example is in a cabin lighting a first group of lighting devices for ceiling or corridor lighting and a second group, the reading lamps or

Make seat lighting. A third group can be used for floor lighting and escape route marking.

It will be apparent to those skilled in the art that those described above

Embodiments are to be understood by way of example and the invention is not limited to these, but can be varied in many ways, without the

To leave the scope of the claims. It is also to be understood that the features, independently as they are disclosed in the specification, claims, figures, or otherwise, also individually define essential components of the invention, even if described together with other features.

The following is an exemplary embodiment of a parameter set in

Data storage module 9 explained. For a lighting system that works with 3 digital control lines for 10%, 50% and 100% brightness, the following parameter set could be used. The lighting system is for a passenger plane, here specifically the

Passenger cabin provided. The 3 control lines allow the dynamic selection of up to 8 (2 ³ ) different color or lighting scenarios, whereby the scenarios can vary depending on the location (but fixed). The physical units used are generally device-independent, ie colors are z. Ex. Specified in the standard color space CIE 1931 instead of in the individual intensities of the lamps used. This allows the use of

Memory units beyond a single luminaire class.

In Fig. 4, an interior is shown, which with a

Lighting installation 1 is equipped with a plurality of lighting devices according to the present invention. The lighting devices are installed so that only the different light exit elements are visible in the interior. By way of example, the light distribution on the ceiling is in the form of light points 301 (not all designated for clarity) with only a small diameter of at most one centimeter, but preferably less so that the impression of a starry sky is realized. The points of light can be direct are formed by the light sources 3 of the lighting devices, or may be light leaks from light guides connected to the light sources. At the bottom, the light distribution in a central area is flat, here exemplified in the form of a rectangular light tile 302. Such a light tile can be useful, for example, for the formation of so-called "bottom lights". In the lateral floor area of the interior shown here, the light distribution takes place in the form of Linienlichtem 303. By way of example may be marked with such Linienlichtem 303 podiums in the ground. It is also possible to realize in this way an orientation lighting for the identification of escape routes. By means of circular (330) or rectangular (332) Finienfühmng it is also possible to mark special places in the interior, for example in the form of a contour lighting of windows (331) or frame (333). In the upper wall area, a further Finienlicht 303 is still shown. Finally, one can

Lighting device 3 can also be realized as a fence lamp 304, which is shown here schematically in the right wall area.

It is furthermore possible to tune this lighting installation 1 to one another by means of a sensor 70 as well as to extrinsic effects, for example daylight falling through the window 331. This is arranged here by way of example in the front side of the interior equipped with the lighting device according to the present invention. However, it is also possible to attach this sensor 70 to another location which is particularly sensitive with regard to interior lighting. It may also be useful to combine different lighting device groups and tune with different sensors.

For example, it may be useful to have a sensor for extrinsic effects in the

Floor area of an aircraft cabin to arrange, since this area is far less affected by falling from the window of the cabin spruce. In this way it can be ensured that depending on the

Overall brightness of the aircraft cabin the orientation lighting to

Escape route marking is always clearly visible, but without it during the

Nachtzeitruhe of the flight to an impairment of the passengers by disturbing spruce effects (so-called Fichtverschmutzung) comes. The various illumination devices can then form groups as explained with reference to FIG. 3.

Such groups may be useful, for example, to illuminate the ceiling light with a different color or brightness than other lights, such as orientation light. Within the respective group, the individual lighting devices can be matched to each other in terms of color and brightness, so that as far as possible no differences in brightness and color are perceptible.

In the example shown in Fig. 4, for example, the punctiform

Light distributions 31 are generated on the ceiling by a plurality of lighting devices, which are operated together with a first group 30. As a second group 31, for example, the lighting devices for the linear

Light distributions 303, 330 332 are summarized so that they shine in a uniform hue with the same brightness. This can then differ if necessary from the hue of the point-shaped light distributions, the

different values can be set in groups.
