    METHOD FOR CONTROLLING AN ADAPTIVE LIGHTING DEVICE AND LIGHTING SYSTEM FOR PERFORMING THE PROCESS
    1. FIELD OF THE INVENTION
    The present invention relates to a method for controlling an adaptive lighting device, in particular for illuminating a goods display surface, as well as a lighting system for carrying out such a method.
    2. BACKGROUND
    In department stores, shops, especially in grocery stores, frequently white illumination is used, for example, with a relatively high proportion of red, green and / or yellow light, in order thereby to facilitate the presentation of goods, for example reddish, greenish or yellowish goods (in particular meat , Vegetables or cheese). In this case, a dominant color or a dominant color component of the product display area or the product to be illuminated is frequently amplified (for example, red for meat products, green for vegetable products, yellow for cheese and bread products), thereby giving the consumer a particularly positive color impression to arrange the goods.
    In this case, illuminations or light sources are used, which can add a specific peak or secondary peak (in particular red, green or yellow color range) to the radiated light depending on the lighting situation. Such a luminous means is disclosed in the prior art, for example in the form of a light-emitting diode module in the document DE 202008 005 509 U1. Such a light-emitting diode module is preferably used in the present inventive method or in a lighting system according to the invention.
    In such a light-emitting diode module, the operator can manually adjust the radiated light to the respective concrete lighting situation. The operator must assess independently which specific lighting (in particular which color peaks or color secondary peaks) matches the surface to be illuminated or to the illuminated products. It is problematic that the adjustment of the lighting is based solely on the subjective color perception of the operator.
    In the prior art, therefore, illuminations have been developed which include an implemented sensor system by means of which the actual illumination is automatically made to the respective area to be illuminated in order to be able to adjust the illumination independently of the subjective perception of an operator. Such lighting with implemented sensor technology is disclosed, for example, in the document EP 2 541 362 A1. In this case, the sensor implemented in the illumination detects at least one dominant color of the surface to be illuminated or the product to be illuminated and automatically controls the illumination accordingly.
    Although this solution is independent of the subjective color or lighting perception of an operator, however, such a solution is also relatively expensive, since a corresponding sensor system is to be provided in each lighting. In addition, the sensor must be calibrated regularly to ensure optimum control of the illumination. Finally, it has also been found in practice that the sensor has a comparatively high susceptibility to interference or failure, which is due to its relatively high thermal stress within the illumination.
    Based on this prior art, the present invention has the object to provide a method for controlling an adaptive lighting device, in which the above-mentioned disadvantages of the prior art are eliminated or reduced.
    In particular, the present invention has the object of providing a method with which an adaptive illumination device (which preferably comprises a light-emitting diode module disclosed in the publication) as simply as possible to a surface to be illuminated or to a product to be illuminated can be adapted without having to depend on the subjective perception of color by an operator or without having to provide expensive and therefore expensive sensors in a lighting device. Moreover, an illumination system with which the method according to the invention is carried out should be specified can.
    [0009] These and other objects, which will become apparent upon reading the following description or which will be recognized by those skilled in the art, are achieved by the subject matter of the independent claims. The dependent claims further develop the central idea of the invention in a particularly advantageous manner.
    3. DETAILED DESCRIPTION OF THE INVENTION
    The method according to the invention for controlling an adaptive illumination device, in particular for illuminating a product presentation area, comprises the following steps: [0011] Providing an adaptive illumination device comprising: at least one
    Light-emitting diode module (LED module), which is set up to emit light with a specific spectrum; a control unit for controlling the light output of the LED module; and an interface for wireless communication; [0012] Providing a mobile terminal comprising an interface to the wireless
    Communication and at least one digital camera unit; Providing a digital image of the area to be illuminated by the adaptive illumination device and / or an object to be illuminated by the adaptive illumination device by means of the camera unit of the mobile terminal; Performing an analysis of the digital image and determining at least one of the dominant color in the digital image; [0015] - Control of the LED module by the control unit in such a way that it emits light with a specific spectrum as a function of the dominant color of the digital image determined.
    The method according to the invention therefore proposes to make a digital image of the surface to be illuminated by a mobile terminal (for example a digital camera or a smartphone) and to analyze this digital image, instead of the above-mentioned relatively complex and complex sensor systems to be assigned to a respective illumination unit And to determine at least one dominant color component of the digital image.
    In other words, the method according to the invention proposes to replace the sensor system disclosed in the prior art by a digital camera of a mobile terminal, which can be used for all the lighting devices to be adjusted, for example located in a department store.
    Under an active lighting device according to the invention is any (spekt¬ral) adjustable or controllable lamp module - in particular an LED module - to understand that can give off a specific light spectrum (eg, by a white light or more specific (selected) To be able to mix (color) peaks or (color) secondary peaks or to be able to add a specific color content to the white light in order to be able to provide an adapted (continuous) spectrum, for example). As already stated above, the process according to the invention is carried out Preferably, an LED module is used, which is disclosed in the document DE 20 2008 005 509 U1. In principle, however, other (spectrally) adjustable or controllable luminous means (modules) are also conceivable which fulfill the aforementioned properties. For the sake of simplicity, the following will be referred to as the "LED module" or "light-emitting diode module", wherein correspondingly other illuminants are also included in principle by the invention.
    Under a control unit according to the invention an adaptive lighting device is to understand any unit that is capable of control commands (for example, transmitted by the mobile terminal) for the adaptive lighting device for Steue¬ung the light output of the LED module to process or based on the analysis data of the digital image (for example, transmitted by the mobile terminal) can make a corresponding control of the LED module.
    The digital image can be angefer¬tigt of the entire surface to be illuminated or even from a aufzustellenden on the surface to be illuminated product unit. For example, a digital image of the entire display (e.g., a vegetable, meat, cheese, or bread display) can be made, or even from a product representative of the exhibit.
    In the present case, the term dominating color can be understood to mean an exact color (location) point (for example given by a wavelength of light wavelength) or a more or less wide color (location) area or spectral range (for example given by a range of light wavelengths) , In other words, the term dominating color is understood to be non-limiting as a punctual color value / location.
    Usually, the dominant color of meat products is red, of bread and cheese products yellow and green vegetable products. Preferably, these products are irradiated with a light which corresponds to the determined dominant color (ie, for example, a meat display with a (white) light with an increased red content, a bread or cheese display with an increased yellow content and a vegetable display with an increased green content are illuminated). ,
    However, there may be lighting situations where it is desirable to add to the light emitted by the LED module a color component (e.g., a peak or minor peak) that does not correspond to the determined dominant color. This can be the case, for example, with lighting of textile displays, exhibits in museums / galleries, in conference rooms or workplaces. In addition to color blends in the red, yellow and / or green color range, therefore, color blends in all other conceivable (visible) colors or color ranges are additionally or alternatively conceivable.
    With a method according to the invention, in particular the integration of a mobile device which is mostly present anyway for detecting a digital image of a surface to be illuminated or an object to be illuminated, it is therefore possible to dispense with additional sensor systems or detection devices, in particular in the luminaire itself , and thus to be able to provide a much simpler, more cost-effective and reliable control of an adaptive lighting device.
    Advantageously, the mobile terminal is a digital camera or a smartphone with at least one digital camera, with which a digital image in raw data format ("raw data"), in JPEG format ("File Interchange Format") or in TIFF format ("Tagged Image FileFormat") can be provided.
    The use of existing mobile terminals, such as a digital camera or smartphone, has the advantage that the result is scalable; e.g. high-end with good digital camera and high-resolution or low-end photos with smartphone and lower-resolution photos.
    The provision of the digital image in the raw data format has the advantage that, when analyzing this data, there is no danger of color losses or defects due to compression of the data. Insofar as a compression of the raw data desired. is necessary, it has been found in practice that when providing the digital image in JPEG format or in TIFF format, an analysis of the digital image can be made with a sufficiently high and reproducible quality.
    Advantageously, when analyzing the digital image, the brightness, the size of the surface to be illuminated or the surface finish of the surface to be illuminated or of the product to be illuminated (for example, whether it is reflecting or absorbing) are also analyzed. Advantageously, driving of the LED module not only takes place with respect to the color of the emitted light of the LED module, but also includes adjusting the light emission angle, the light brightness, the light intensity and / or the light distribution. By including these further parameters on the one hand with respect to the analysis of the digital image and on the other hand with respect to the driving of the LED module, it is possible to analyze a surface to be illuminated relatively accurately and to generate an individual, i.e., an image. to make a precisely adapted to the particular lighting situation, setting the LED module.
    In a first preferred embodiment, the digital image is transmitted wirelessly from the mobile terminal device to the adaptive illumination device, wherein an analysis of the transmitted digital image is performed by a data processing program of an image analysis unit of the adaptive illumination device.
    Preferably, the data processing program of the image analysis unit is embodied as an embedded data processing program (so-called "embedded software").
    The image analysis unit, comprising a corresponding data processing program for analyzing a digital image, can already be provided at the factory in the adaptive lighting device.
    By such a configuration, there is a possibility that an operator creates digital images of the surface to be illuminated or the object to be illuminated by means of a commercially available mobile terminal (in particular by means of a digital camera or a smartphone) and transmits them wirelessly to the adaptive illumination device, for this purpose no special adaptation or no special Datenverarbeitungs¬ program must be provided on the mobile device. In other words, in this embodiment it is possible to carry out a method according to the invention by means of commercially available mobile terminals, in particular without having to provide special hardware or software in the mobile terminal. For simplified operation, it may at best be provided to provide a corresponding app on the mobile terminal. This applies to all conceivable embodiments of the present invention.
    In a second preferred embodiment of the present invention, the digital image analysis is performed by a data processing program stored on the mobile terminal, the mobile terminal providing control data (ie, either immediate control commands for controlling the light output of the LED module or corresponding image analysis data). with the control unit can provide the drive parameters or direct control commands for the LED module) to the control unit of the adaptive lighting device for driving the light-emitting diode module transmits.
    In contrast to the first embodiment, the analysis of the digital image in the second embodiment takes place in the mobile terminal, which has for this purpose a corresponding data processing program (for example an application software in the form of a so-called app) or has stored.
    Such an embodiment has the advantage that the data processing program for analyzing the digital image can be loaded or updated via the already existing mobile radio interfaces of the smartphone. In other words, this makes it possible to equip operators in a simple manner with a corresponding data processing program or to be able to update or maintain this regularly.
    In a third preferred embodiment of the present invention, the mobile terminal transmits the digital image to a central processing unit, the analysis of the digital mapping being performed by a data processing program stored on the central processing unit.
    Such an embodiment again has the advantage that no special hardware or software has to be provided on the mobile terminal and a transmission of the digital mapping to a central computer unit can be effected via an existing mobile radio network. In this case, the central computer unit can transmit the control data directly to the control unit of the adaptive lighting device for activating the light-emitting diode module if corresponding interfaces are present on the adaptive lighting device. Alternatively, the central computer unit first transmits the control data to the mobile terminal, which subsequently transmits the control data to the control unit of the adaptive lighting device for activating the light-emitting diode module.
    Preferably, for driving the light-emitting diode module is resorted to a stored in the mobile terminal, the lighting unit or the central processing unit database in the predefined lighting patterns or control commands for driving the light-emitting diode module are deposited, based on the database analyzed and / or determined Data, the predefined illumination pattern or control commands are zugeord¬net and the light-emitting diode module is driven based on this assignment. It is thus possible to provide predefined control commands or lighting patterns for a drive which can be easily determined on the basis of the actually determined analysis data (for example dominant color). In this way, complex arithmetic operations can be dispensed with and the driving is performed safely and quickly.
    Preferably, the wireless communication between the mobile terminal and the adaptive lighting device via a wireless local communication network, in particular a Wi-Fi network or a WLAN. Alternatively, the wireless communication between the mobile terminal and the adaptive lighting device may also be by means of an RF / DC transmission, a Bluetooth transmission or a ZigBee transmission.
    The invention further relates to an illumination system for carrying out a method according to the invention, wherein the illumination system comprises at least the following: [0041] an adaptive illumination device according to the invention, with at least one LED
    Module configured to emit light of a specific spectrum; a control unit for controlling the light output of the LED module; and an interface for wireless communication; [0042] - A mobile terminal, comprising an interface for wireless communication and further comprising at least one digital camera unit for detecting a digital imaging of the area to be illuminated by the adaptive illumination device and / or a Ge to be illuminated by the adaptive illumination device gens tandes; - An analysis unit suitable for performing an analysis of the digital image, wherein at least one dominant color of the digital image is determined, and whereby the LED module is controllable in dependence of the determined dominant color of the digital image.
    4. DESCRIPTION OF A PREFERRED EMBODIMENT
    In the following, a detailed description of the single figure 1 is given, which shows a schematic view of a lighting system according to the invention.
    FIG. 1 shows a schematic view of a lighting system according to the invention, comprising an adaptive lighting device 100, which is designed to illuminate a heat presentation surface 110, on which goods 120 are arranged. Furthermore, the illumination system according to the invention comprises a mobile terminal, in the form of a smartphone 130 in the present case.
    In this case, the smartphone 130 comprises a data processing program (preferably a so-called application software in the form of an "app") which, for example, is transmitted to the smartphone 130 via an existing mobile radio network and stored thereon.
    To control the light emitted from the adaptive lighting device 100, the operator first prepares a digital image (digital photo) of the merchandise display surface 110 to be illuminated.
    Alternatively, it is also possible for the operator to create a digital image of a product 120 that is color-representative of the goods presentation area 110. Furthermore, there is the possibility that the operator not only creates a digital image of the merchandise presentation area 110 or the merchandise 120, but also creates a plurality of digital images that can be used as a basis for a subsequent image analysis.
    The digital image is preferably provided in JPEG format. Alternatively, however, raw image data (TIF) or Tagged Image File Format (TIF) or other digital image formats may also be used.
    After the creation of a digital image of the merchandise display area 110 or the merchandise 120, an analysis (image analysis) of the digital image is carried out by means of the data processing program which is stored on the smartphone 130. In this case, at least one dominant color of the digital image is determined (for example, in the case of a cheese display, yellow is usually used as the predominant color, usually red in the case of a meat display and usually green in the case of a vegetable display). The dominant color can also be determined, for example, by marking / selecting a color area or a product, for example on a sensitive display-operator interface (for example a touchscreen) 140 of the mobile terminal device 130 (manually).
    In the analysis of the digital image, further parameters, such as the brightness, the size of the merchandise display area 110 to be illuminated or the merchandise 120 and the surface condition (eg reflections, surface structure, etc.) of the merchandise display area to be illuminated, are preferably also used 110 or the product 120th
    Alternatively, it is also possible to transmit the digital image directly to the adaptive lighting unit 100 or to a central computer unit or control unit (not shown), so that in this case the analysis of the digital image either in the adaptive Lighting device 100 or in the central computer unit by means of a data processing program existing there. The central control or computer unit can be connected to the lighting unit wirelessly (for example via WLAN) or wired (for example via DALI).
    In the analysis, data obtained from the scene to be lit (eg, fruit basket, meat counter, conference table, etc.) recorded by the digital camera unit (color location, brightness, size of the object, surface type and structure (e.g., specular or not), etc.). ) determined from the digital photo. After the analysis of the digital image and the determination of a color dominant in the merchandise display area 110 or on the merchandise, corresponding control commands are transmitted by the smartphone 130 to the control unit of the adaptive illumination device 100 by means of corresponding interfaces for wireless communication.
    Preferably, wireless communication takes place between the smartphone 130 and the adaptive lighting device 100 via a wireless local communication network, in particular a Wi-Fi network or a WLAN, alternatively also an RF / DC transmission, a Bluetooth transmission or a ZigBee Transmission can take place.
    The data which are thereby transmitted to the adaptive illumination device 100 may in this case already be direct control commands for the adaptive illumination device 100 or else only analysis data, with the aid of which the control unit of the adaptive illumination device 100 can set the light output accordingly.
    After the transmission of the corresponding control data by the smartphone 130 to the adaptive illumination device 100, a corresponding control of the emitted light takes place as a function of the ascertained dominant color of the digital image. For example, it has been determined that the dominant color of the goods presentation surface 110 is yellow (for example in the case of bread or cheese goods), for example, a portion of yellow may be added to the light emitted by the adaptive illumination device 100 in order to improve the subjective color impression of these goods for a viewer. It is also preferably determined in the image analysis with which light emission angle, with which light intensity and / or with which light distribution light is emitted from the adaptive illumination device 100, in order to enable an optimal presentation of the goods.
    In order to make possible a simple control of the light-emitting diode module from the determined data, it is possible to resort to a database with predefined illumination patterns or control commands on the basis of the analyzed or determined data (that is to say the dominant color or further data) be predefined (groups of) to be determined analysis data certain lighting patterns or control commands are zugeord¬net. Thus, corresponding color spectra or other settings of the illumination unit 100 as illumination patterns or control commands can be stored in this database for corresponding predefined regions of selected data (for example, detected color locations).
    The illumination unit 100 or the LED module is then actuated by means of the illumination patterns or control commands assigned to the ascertained / analyzed data from the database. The database can be stored in the mobile terminal 130, the lighting unit 100 or in a central computer unit.
    As can be appreciated by those skilled in the art, the method according to the invention thus provides the possibility of a single "sensor" in the form of a mobile terminal (preferably a smartphone or a suitably equipped digital camera) for controlling / adjusting a plurality of adaptive lights arranged in a warehouse ¬tungsvorrichtungen to use.
    Compared to the prior art, therefore, there is a considerable cost advantage, since in the prior art so far a corresponding sensor system must be assigned to each respective adaptive illumination means. Moreover, the method according to the invention makes it possible to use essentially any commercially available smartphone on which a corresponding data processing program can be loaded for carrying out a method according to the invention.
    It should be noted that the present invention is not limited to a method and a lighting system for illuminating a goods display area, but also in museums, in conference rooms, at workplaces, in public spaces, on facades, in street lighting and the like can.
    Also, the control of the adaptive illumination device is not limited to amplify a determined dominant color of the surface to be illuminated or the product to be illuminated such that the light emitted in the range of the dominant color is added to the radiated light or the Light in the (spectral) range (specific spectrum) of the dominant color radiates, but it may also be desired to provide a color component or a color that / does not correspond to the Dominie¬renden color. In addition, the proportion of light which can be added to the emitted (white) light or the specific spectrum is not limited to the color green, red and yellow. Moreover, it will be apparent to those skilled in the art that the vorbeschriebe¬ preferred embodiments can be combined with each other in any way.
    The features of the present invention can be combined with one another in any manner and under one another.
