    [0001] The invention relates to a management system of a park of lighting devices, such as streetlights, equipping for example a district of a city.
    [0002] BACKGROUND OF THE INVENTION The invention relates generally to the maintenance of a park of lighting devices equipping for example a district of a city. At present, the detection of defective lighting devices is provided by a technician who regularly turns when the lighting devices are turned on to visually detect those which do not light or insufficiently. When defective lighting devices are detected, a maintenance and / or repair team intervenes on each defective lighting device in order to intervene on or replace the luminaire of these lighting devices. Since lighting devices are typically installed at heights of between four and ten meters, it is generally necessary to mobilize a pod and several technicians for each intervention on a lighting device, or even simply to make a diagnosis of a light. defective lighting device. This maintenance results in very high intervention costs and operating costs, in addition to the significant costs already represented by the electricity consumption itself of a lighting equipment park. 30 In order to reduce overall lighting usage costs, municipalities are increasingly using lighting devices with complex technologies, which can be controlled from a central unit, incorporating multiple dimming of lighting power depending on the lighting system. the time zone, the season etc. All of these elements give rise to complex lighting systems, whose remote control is complicated by the fact that the identification of lighting devices is not precise and requires tedious procedures to ensure that the centralized unit can reliably know the location and identification of each lighting device it is piloting. OBJECT OF THE INVENTION The object of the invention is to propose a solution to overcome these disadvantages. SUMMARY OF THE INVENTION To this end, the subject of the invention is a lighting device incorporating a luminaire, characterized in that it is equipped with Li-Fi type transmitting means for transmitting a signal comprising: identification data of the luminaire; Data representative of the operating state of the luminaire. The invention makes it possible to remotely diagnose the luminaire from the ground quickly and more economically than with known solutions. The census of a set of luminaires and their operating states can be performed during a round simply by using a Li-Fi receiver to transcribe the data contained in the Li-Fi signal emitted by each lighting device. . Rounds can be 30 times faster and more accurate. The invention also relates to a lighting device as defined above, wherein the identification data comprise: - an identifier of the luminaire and optionally; data representative of the type of luminaire and / or; representative data of the constituent components of the luminaire; and wherein the information representative of the operating state of the luminaire comprises: data meaning that the lighting device has normal operation or that it has a malfunction, and possibly; - data representative of the luminaire settings. The invention also relates to a lighting device as defined above, wherein the signal emitted Li-Fi further comprises: - data representative of the total time during which the lighting device has worked; maintenance data such as a value representative of a time remaining until replacement of the luminaire. The invention also relates to a system comprising lighting devices as defined above, as well as a receiver module integrating a receiver member Li-Fi and storage means, for receiving and recording the Li-Fi information from of a lighting device when this receiver module is in the light field of said lighting device. Such a receiver can thus be mounted on a road vehicle, such as a garbage truck, which allows for rounds to identify lighting devices and their operating conditions without having to mobilize a specialized technician.
    [0003] The invention also relates to a system comprising lighting devices as defined above, wherein the receiver module comprises a mobile device type electronic tablet or smartphone equipped with a receiver Li-Fi integrated or connected to this device mobile, and means for further transmitting the collected data in real time by GSM type data transfer link. The invention also relates to a system comprising lighting devices as defined above, wherein the receiver module comprises geolocation means for associating with each received Li-Fi data geolocation data of the reception location. of these data transmitted by Li-Fi. DETAILED DESCRIPTION OF THE INVENTION The idea underlying the invention is a lighting device comprising a luminaire and which is equipped with data transmission means Li-Fi, to transmit from this device of illumination, substantially continuously and Li-Fi, data to identify the lighting device and to know its operating status. Li-Fi technology consists in transmitting wireless data from a luminaire to a receiver module, by means of luminous flashes generated by the luminaire and perceived and decrypted by the receiver apparatus. It has been booming since the popularization of LED type lights which can easily be flickered to blink at relatively high frequencies to emit a signal. In practice, the lighting device according to the invention is equipped with diagnostic means making it possible to determine the operating state of its luminaire, such as for example its lighting power (characterized by the luminous flux), as well as possibly other operating parameters. By way of example, the lighting power can be determined on the basis of the electrical power consumed by the luminaire.
    [0004] These diagnostic means may for example additionally integrate memory elements, for example to continuously update a history of the operating state of the lighting device, for example hour by hour over the period of the last twenty-four or forty-eight hours have elapsed. These diagnostic means which are integrated in the lighting device or the luminaire per se also keep in memory an identifier of the luminaire which is for example a unique identifier stored in the luminaire during its manufacture or when it is put into service. The lighting device or the luminaire may advantageously also be provided to be controllable from a network such as a data transmission network to which it is connected. This network can be a powerline data transmission network, whereby a set of lights in a district or a district of a city are controlled jointly from a single central unit. In concrete terms, the central unit then controls each lighting device so that it illuminates according to a power conditioned for example by the level of use by pedestrians of the zone it illuminates, this level of attendance being derived from a base of regularly updated data, and to which the central control unit of the luminaires accesses. The Li-Fi data transmission module of the lighting device is, for example, a control circuit for the lighting components of this luminaire, such as the LED components so that they flash in a given sequence, at a certain speed. relatively high frequency, so as to transmit the signal to be transmitted. Li-Fi data transmission is performed by means of any modulation adapted to this type of transmission, such as NRZ-00K modulation. This signal is emitted for example continuously, or during a certain predetermined time range corresponding to the beginning or the whole evening. As will be understood, the signal that is transmitted Li-Fi comprises a set of data advantageously comprising identification data of the luminaire and data representative of its operating state. The identification data may, as indicated above, include an identifier of the lighting device, but may also include data indicating what is the type of lighting device, and what are its components. The data representative of the operating state of the lighting device may comprise, as indicated above, data reflecting its lighting power, but also significant data of a malfunction of the luminaire, for example in the case where a part of the LED lamps that compose it are out of order.
    [0005] The state of failure or malfunction can be detected by the diagnostic module on the basis of a comparison between the electrical power consumed by the luminaire and the electrical power that it should consume, taking into account where appropriate instructions from he received from the central unit to which he is connected. More generally, the state of malfunction can result in insufficient light flux resulting in a low power consumption.
    [0006] The diagnostic means can thus determine that the lighting device is malfunctioning when the electrical power that it consumes is aberrant with respect to one or more predetermined criteria or transmitted by the central unit. The data transmitted via the Li-Fi channel may also include data representative of the operating settings of the luminaire, data representative of the total number of hours of operation of the luminaire, or data representative of the time separating the luminaire from its end of life, that is to say of his replacement. The data is collected with a Li-Fi reception module, for converting the data transmitted by the lighting device, for example in the form of textual information that can be displayed on a screen. Advantageously, the Li-Fi reception module comprises a mobile electronic device of the tablet or smartphone type, integrating geolocation GPS means and an external Li-Fi module to which this mobile electronic device is connected. The module may advantageously be designed to be mounted on a road vehicle such as for example a garbage truck or any other vehicle that regularly makes tours in one or more areas of the city equipped with the Li-Fi lighting system. according to the invention. Advantageously, the reception module is connected to a network of the mobile network type, such as for example a GSM network. During the tour with such a module, the acquisition is provided in a fully automated manner: when the module is in the lighting field of a lighting device, it receives the Li-Fi information it decrypts, and that it completes by adding its location, for example in the form of GPS coordinates. Once the data has thus been decrypted and completed, they can be directly transmitted to a centralized management server, by GSM transmission. The invention provides the following advantages in particular: The invention allows an exact identification of the lighting device directly from the ground: it is no longer necessary to read a reference inscribed in the same lighting device, and thereby implying to have a lifting platform. It is thus possible to use technology luminaires that are both more complex and more specific. The invention makes it possible to precisely identify and locate each luminaire very rapidly for the entire network. It thus simplifies the centralized management of a luminaire park, from a central unit addressing the luminaries instructions via a data transmission network, since there is no longer any ambiguity with regard to the identification and the location of each lighting device controlled from the central unit. In other words, it is no longer necessary to control via the central unit a lighting device for it to flash for a technician to identify it.
    [0007] When rounds are regularly made, they make it possible to quickly identify the defective lighting devices, since they emit in their signal data representative of their malfunctions. It is thus possible to then send a repair team directly to the site while having previously defined remotely the operation to be performed.
