    OFFLINE COMMISSIONING OF A LIGHT
    1. FIELD OF THE INVENTION
    The present invention relates to a lamp, a device for transmitting light signals to such a lamp, a system comprising such a lamp and such a device and finally a method for starting such a lamp with such a device.
    2. BACKGROUND
    In the prior art lighting systems are known which comprise a plurality of controllable lights and lamps. Lamps and luminaires of such lighting systems are usually controlled by means of a central control unit, the luminaires being connected to a corresponding network for this purpose. For clear assignment and correct control of the luminaires in the network, luminaires are assigned unique luminaire addresses when the lighting system is put into operation, with the aid of which the lighting control system can control the respective luminaires later.
    The commissioning of such lighting systems is often a costly and therefore costly process. Typically, the luminaires of such lighting systems are first mounted and connected in a subsequent step to the electrical supply and to a corresponding bus system (for example to a so-called DALI system ("Digital Addressable Lighting Interface").) However, as long as the luminaires are not yet connected to an external power supply are connected and there is no correct cabling of the bus system, the luminaires can not be parameterized or provided with corresponding luminaire addresses, but in practice there is often the problem that it is only determined during commissioning of the lighting system that In this case, commissioning must be stopped in order to provide correct cabling of the luminaires first, and only then can the luminaire system be put back into operation, which in practice takes a considerable amount of time. and costs incurred. Based on this prior art, the present invention has the object to provide a lamp that can be put into operation even if it is not yet connected to an external power supply and to a corresponding bus system or made no correct wiring of the lamp has been.
    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 form the central idea of the present invention in a particularly advantageous manner on.
    3. DETAILED DESCRIPTION OF THE INVENTION
    A luminaire according to the invention comprises: at least one energy-generating circuit having at least one semiconductor element for receiving light signals and generating a photocurrent; at least one processing module for processing the light signals received by the semiconductor element; and at least one memory device for storing data provided by the processing module, wherein the processing module and the memory device are connected to the power generation circuit so as to be operable by the photocurrent of the semiconductor element.
    An energy harvesting circuit of a luminaire according to the invention thus serves on the one hand to receive light signals (eg. By "Visible Light Communication") and on the other hand to generate a photocurrent when the light signals hit the semiconductor element.
    The semiconductor element is preferably a light emitting diode, a photodiode or a semiconductor thin film system, wherein a plurality of semiconductor elements can be connected in series or in parallel, depending on the embodiment and depending on the energy requirements of the modules connected to the energy harvesting circuit.
    The power generating circuit may include an energy harvesting solution used in solar technology ("Energy Harvesting") (for example, an LTC3105 Linear Technology power generation circuit).
    The processing module is used for processing / processing of the received light signals from the semiconductor element, the processing module for this purpose may include filters, amplifiers, etc., to generate from the receiving light signal a usable / memory-res-signal (for example, a digital signal).
    A memory device according to the invention serves to store the data provided by the processing module (for example, parameter data for later operation of the luminaire, a luminaire address, etc.).
    An essential aspect of the present invention is that at least the processing module as well as the storage device are connected to the power generation circuit such that they are operable by means of the photocurrent.
    This makes it possible to take a luminaire according to the invention into operation (ie to transmit to the luminaire a corresponding luminaire address, parameter data, etc., which are necessary for the subsequent operation of the luminaire), even if they are not yet an external power supply and / or is connected to a corresponding bus system.
    For commissioning a lamp according to the invention thus only one light source must be directed to the semiconductor element, wherein the light source is preferably a pulsed or a modulated light source in order to transmit corresponding data to the light can. A commissioning of a lamp according to the invention can thus be carried out at any time, in particular after installation of a lamp according to the invention, even if no or no correct wiring of the lamp has been made. In other words, a luminaire according to the invention can be put into operation completely "offline", so that the commissioning costs can be significantly reduced as a result, since the provision of correct wiring of a luminaire is no longer necessary.
    Furthermore, results from a luminaire according to the invention increased flexibility in the programming of a lighting system, since, for example, an accidentally incorrectly programmed light can be simply corrected by re-transmitting the data by appropriate light signals. This possibility does not exist in the majority of the known lighting systems, since they have to be programmed, for example, in a DALI installation along the wiring harness (ie one behind the other).
    Advantageously, the energy harvesting circuit further comprises at least one energy storage device for storing the photocurrent, wherein the energy storage device preferably comprises an accumulator and / or a (charge) capacitor. This makes it possible to store the photocurrent that was generated in the semiconductor element before the lamp is put into operation (for example, when daylight strikes the semiconductor element after the luminaire has been mounted) for later use. Furthermore, there is the advantage that, prior to the transmission of a pulsed or modulated light signal, a constant intense light is directed to the semiconductor element for a certain time in order to charge or at least partially charge the energy storage device. As a result, any fluctuations in the photocurrent due to the pulsed or modulated light signals during data transmission can be compensated.
    Furthermore, it is advantageous that the energy recovery circuit comprises a charge controller to provide an adjustment of the power generation circuit to different high photocurrents due to different light irradiation, wherein the charge controller is preferably a maximum power point controller ("Maximum Powerpoint Controller"). In particular, if the lamp includes an energy storage device that is charged prior to startup (for example, by daylight exposure), this provides the possibility to provide an adaptation to different light intensities. Such charge controllers, in particular maximum power point controllers, are known, for example, from photovoltaics.
    Preferably, the memory device for storing data comprises a non-volatile memory, so that the data provided by the processing module (in particular a luminaire address assigned to the luminaire, the parameters to be set for later operation of the luminaire, etc .) can be permanently stored in the memory device and this no additional energy from the power generation circuit is needed. The non-volatile memory is preferably a flash RAM.
    Advantageously, the memory device for storing data comprises a microcontroller, in particular a low-power microcontroller ("Ultra Low Power Microcontroller"). Microcontrollers, in particular low-energy microcontrollers, are particularly preferably used in luminaires according to the invention, since they comprise a multiplicity of operators and interfaces which are advantageous for later operation of a luminaire according to the invention and microcontrollers can be equipped with corresponding memory modules.
    Furthermore, it is advantageous if the luminaire according to the invention comprises an interface for wireless communication, which is connected to the energy-generating circuit such that it can be operated by means of the photocurrent of the semiconductor element. Preferably, the wireless communication interface is a Bluetooth interface, a ZigBee interface, a WiFi interface, or a WLAN interface. This provides a simple way to construct a bidirectional connection to a lamp according to the invention, for example, to transmit device data of the lamp (for example, type data of the lamp, the device-dependent parameters, etc.) to a correspondingly equipped receiver and this for a later operation of the lighting system to provide a central control unit.
    Advantageously, the lamp comprises a feedback means which is connected to the power generating circuit such that it is operable by means of the photocurrent of the semiconductor element. The purpose of such a feedback means is to give an acoustic or optical feedback after storage of the transmitted data in the memory device and thus to indicate to the user a successful transmission of the data directly. The feedback means is preferably a light-emitting diode or a loudspeaker, so that a corresponding acoustic or optical feedback signal can be emitted by the light.
    Further, it is advantageous if the lamp comprises an optical filter means for filtering the light impinging on the semiconductor element. For example, this makes it possible to filter out disturbing daylight that impairs the accuracy of the data transmission by means of the light signals. In addition, this makes it possible to adapt the luminaire according to the invention to the reception of a precisely defined light (for example, to the light of a laser diode). In this case, the optical filter means can be arranged fixedly in front of the semiconductor element or only be arranged in front of it when the light signals are transmitted. The latter is particularly advantageous if an energy storage device is provided and this is to be charged in advance by means of daylight.
    Advantageously, the semiconductor element is arranged to receive light from a laser light source and to generate a photocurrent. Such laser light sources can be provided for example by means of appropriately arranged laser diodes.
    The invention further relates to a device for transmitting light signals to a lamp according to the invention, wherein the device comprises a pulsed or modulating laser light source for emitting a pulsed or modulated laser light. Such a device may be provided, for example, by a compact handheld device having a corresponding laser light source (eg, a laser diode) to direct a pulsed or modulated laser light beam to the semiconductor element of the energy harvesting circuit of a luminaire according to the invention.
    Advantageously, the device is set up to communicate wirelessly with a mobile terminal, in particular with a laptop, a tablet computer or a smartphone. A wireless communication between the device and the mobile terminal can be provided in particular by appropriately provided Bluetooth interfaces, ZigBee interfaces, Wi-Fi interfaces or WLAN interfaces. As a result, there is the possibility that an input of the data takes place on the mobile terminal, so that the device itself can be made relatively compact, since this only has to be set up to transmit a correspondingly pulsed / modulated laser light, and no further input devices (for example a keyboard, a display, etc.) must be provided on the device. The mobile terminal on which preferably the input of the data (for example, a luminaire address to be transmitted, parameters of the luminaire to be set for later operation of the luminaire, etc.) takes place, can already provide the data as control commands for the control of the laser light source and such transferred to the device. Alternatively, there is also the possibility that the mobile terminal transmits only the input data to the device and a conversion into corresponding control commands only in the device (for example, in a correspondingly established control module).
    To enter the data and, where appropriate, implement this in corresponding control commands, a software set up for this purpose (for example a user software set up on a smartphone in the form of an "app") can be provided on the mobile terminal.
    Advantageously, the device comprises means for expanding the laser light, for example, a diffractive optical element (for example, lenses, optical grating, etc.). By such a widening of the laser light, the data transmission can be further simplified, since the user then only has to direct a correspondingly large light cone on the semiconductor element of a luminaire according to the invention and not a punctiform laser beam.
    Furthermore, the device preferably comprises means for projecting information onto a surface. This can be done on the one hand by a corresponding control of the laser beam by means of a control module set up for it or by optical elements arranged for this purpose (for example diaphragms, engravings, etc.). As a result, for example, a type designation of the device, a logo, a target cross or the like can be projected onto the luminaire or the surrounding area of the luminaire in order to provide the user with further information during the startup of a luminaire according to the invention.
    Preferably, the means for projecting information onto a surface comprises a digital micromirror device ("Digital Micro Mirror Device"). Such digital micromirror units are known, for example, from the beamer technology and provide a particularly high degree of flexibility with regard to the information that can be displayed. For example, the transmitted lamp address can be displayed on a surface adjacent to a lamp during data transmission so that the user can immediately receive feedback on the data being transmitted during commissioning of a luminaire according to the invention and can check whether the data currently transmitted are correct and, for example to agree with a lighting plan.
    The present invention further relates to a system with a lamp according to the invention and a device according to the invention for transmitting light signals to a luminaire according to the invention.
    Finally, the present invention relates to a method for starting up a luminaire according to the invention with the aid of a device according to the invention for transmitting light signals, wherein the method comprises at least the following steps: - Providing a luminaire according to the invention and a device according to the invention for transmitting light signals; Sending light signals to the semiconductor element of the luminaire; Processing the transmitted light signals by the processing module of the luminaire; - storing data provided by the processing module.

In the form of a low-energy micro-controller (Fig. 1) shows a partial section of a circuit structure of a luminaire according to the invention. "Ultra Low Power Microcontroller") 130 includes.
    As shown in Figure 1, a filter 140 is preferably arranged in front of the photodiode 110, which filters disturbing stray light and thus improves the quality of the light signal transmission.
    In the preferred embodiment shown, a processing module for processing the light signals received by the light emitting diode 110 is also provided in the power generation circuit 100. The data provided by the processing module are then forwarded to the microcontroller 130 and stored there permanently. Alternatively or additionally, it is also possible to provide a separate memory module (for example a flash RAM).
    The energy recovery circuit 100 may include a charge controller, in particular a maximum power point controller ("Maximum Power Point Controller"). Such charge controllers are known for example from photovoltaics.
    The filter 140 may be formed as a stationary component or as a displaceable or removable component. The latter can be particularly advantageous if the energy storage device (here, the capacitor 120) is to be charged before commissioning, for example, by the photodiode 110 is exposed to daylight and the photocurrent is to be stored in the capacitor 120. In this context, moreover, it is possible to transmit a (charging) light signal to the luminaire prior to the transfer of data in order to charge or at least partially charge the energy storage device so that any fluctuations in the photocurrent are compensated by the pulsed / modulated light signal can be.
    In addition to the microcontroller 130, an interface for wireless communication can furthermore be provided (not shown), wherein this interface is designed, in particular, as a Bluetooth interface, ZigBee interface, Wi-Fi interface, or as a WLAN interface. Advantageously, the interface for wireless communication is connected to the capacitor such that it can be operated by means of the photocurrent of the photodiode 110.
    As an alternative to the photodiode 110 shown, it is also possible to use a plurality of photodiodes, light-emitting diodes or flat-film thin-film systems (that is to say all flat-conductor elements which generate a photocurrent upon incidence of light).
    In the preferred embodiment, the photodiode 110 and filter 140 are configured to receive light from a laser light source and generate a corresponding photocurrent.
    During startup, a pulsed laser light source is preferably used, which can direct a pulsed laser light on the filter 140, which is then converted by the photodiode 110 into a correspondingly pulsed photocurrent. This pulsed photocurrent is then used, on the one hand, to operate the processing module integrated in the energy harvesting circuit 100 and, on the other hand, to operate the microcontroller 130. The processing module converts the pulsed photocurrent into a usable signal (preferably a digital signal). This processed signal is then stored in a memory device of the microcontroller 130, which memory device is preferably a nonvolatile memory device.
    Thus, a luminaire according to the invention can be put into operation "offline" (i.e., without being connected to an external power supply or to a bus system).

As far as an interface for wireless communication is provided, there is also the possibility to read out data necessary for the construction of a lighting system from the luminaire already during commissioning (for example a type designation of the luminaire, fixed luminaire parameters, etc.). As far as such an interface for wireless communication is provided in the luminaire, it is preferred that this is also connected to the energy-generating circuit 100 or to the energy storage device in order to be able to supply it with energy even without external energy supply.

Furthermore, the device preferably comprises a diffractive optical element in the form of a grid 230.
    The interface for wireless communication 200 serves to receive data from a mobile terminal (for example, from a laptop, a tablet computer or a smartphone). The device for transmitting light signals can be set up in this case to process the data received from the mobile terminal and to convert it into corresponding control commands for the laser unit 220 or, if the mobile terminal already transmits immediate control commands, to control the laser unit 220 accordingly.
    In this case, the diffractive optical element 230 serves to widen the pulsed laser light emitted by the laser diode 220 in order to provide a larger area which can be directed to the light-emitting diode 110 shown in FIG.
    FIG. 3 shows a schematic representation of a system according to the invention comprising luminaires 300, which comprise a circuit shown in FIG. 1, a device for the
    Transmitting light signals 400, and a mobile terminal in the form of a smartphone 500.
    To start up the lights 300, a corresponding software (for example, an "app") is first put into operation on the smartphone, wherein the software preferably provides an input surface, with the help of which corresponding data can be entered (for example via a keyboard of the smartphone ).
    Subsequently, the data is transmitted via wireless interfaces of the smartphone 500 and the device for transmitting light signals 400 to the device for transmitting light signals 400. The device for transmitting light signals 400, which comprises a circuit shown in Figure 2, then emits an expanded pulsed laser beam 410, which is directed by the user to a receiving area of the luminaire on which a photodiode 110 is arranged. The pulsed laser beam 410 transmits data on the one hand and also transmits a power supply to the processing module and the storage device for storing data.
    FIG. 4 shows a device for transmitting light signals 400, as is preferably used in the system from FIG. As shown in FIG. 4, in the preferred embodiment shown, the apparatus for transmitting light signals 400 comprises a trigger button 420, with which the output of the pulsed laser beam 410 can be triggered. Also clearly visible in FIG. 4 is the widening of the laser beam 410 by the diffractive optical element 230 shown in FIG.
    FIG. 5 shows an alternative embodiment of a device for transmitting light signals 400 '. In contrast to the embodiment of a device for transmitting light signals 400 shown in FIG. 4, the device for transmitting light signals 400 'shown in FIG. 5 furthermore comprises an optical means for the projection of information. In the embodiment shown in FIG. 5, for example, a logo, a crosshair or the like is added to the pulsed laser beam 410 '. The means for the projection of information can be provided by appropriate apertures, lens engraving or by a special control of the laser diode 220.
    FIG. 6 shows another embodiment of a device for transmitting light signals 400 ", wherein the device for transmitting light signals 400" comprises a digital micromirror device ("Digital Micromirror Device").
