    [0001] The invention relates to the collection of data provided by sensors such as pollution, attendance, meteorological or other sensors typically located in urban areas.
    [0002] BACKGROUND OF THE INVENTION Currently, there are multiple sensors located in urban areas, which make it possible, for example, to determine the number of visitors to a street, its level of sunshine, the outside temperature, the pollution rate, or still any type of data specific to the environment of the sensor.
    [0003] These sensors are generally equipped with radio data transmission systems, which is relatively expensive and complex from a technological point of view. The transmission can still be provided by wired communication, which is also expensive in terms of installation work, or else by power line transmission.
    [0004] In general, it appears that the existing sensors are suitable and efficient, but that they pose a problem globally as regards the transmission of the information they have captured. OBJECT OF THE INVENTION The object of the invention is to propose a solution to overcome this disadvantage. SUMMARY OF THE INVENTION To this end, the subject of the invention is a lighting device comprising a luminaire, characterized in that it is equipped with a Li-Fi signal transmission module, this module being intended to be connected to one or more sensors such as a sun sensor or an external temperature sensor or the like, for transmitting by Li-Fi a signal comprising data supplied by each sensor to which it is connected. The collection of information from each sensor can thus be achieved very simply, by means of a Li-Fi receiver located in the lighting field of the lighting device, so that this collection can be carried out directly from the soil periodically. It is therefore not necessary to provide the connection of each sensor to a complex communication network. The invention also relates to a lighting device thus defined, further comprising one or more sensors directly connected to the Li-Fi conversion and transmission module. The invention also relates to a lighting device thus defined, wherein the Li-Fi conversion and transmission module includes means for storing the data from each sensor for a period of elapsed time of predetermined duration.
    [0005] The invention also relates to a lighting device thus defined, in which the data transmitted in the transmission signal Li-Fi comprise in addition to the data from each sensor, identification data of the lighting device. The invention also relates to a lighting device thus defined, as well as a receiver module integrating a Li-Fi receiver and storage means, for receiving and recording the Li-Fi information from a lighting device when this receiver module is in the light field of said lighting device. The invention also relates to a lighting device thus defined, wherein the receiver module comprises a mobile device type electronic tablet or smartphone equipped with a receiver body Li-Fi integrated or connected to this mobile device, and means for in addition to transmit to a central server the data collected in real time by GSM data transfer link. The invention also relates to a lighting device thus defined, wherein the receiver module comprises geolocation means for associating with each received Li-Fi data geolocation data of the location of reception of these data transmitted by way of Fi. DETAILED DESCRIPTION OF THE INVENTION The idea underlying the invention is to connect sensors to a luminaire, these cpateurs can be mounted on a mat carrying the luminaire or other support nearby. The luminaire is equipped with Li-Fi data transmission means, to transmit through this lighting device, substantially continuously and Li-Fi, data from these sensors.
    [0006] 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 module. It has grown significantly since the popularization of LED-type lights that can easily be flown to blink at relatively high frequencies to emit a signal. The lighting device according to the invention thus comprises a data conversion and transmission module Li-Fi, by which it is able to convert data it receives from one or more sensors to transmit them by Li-Fi way so that they can be collected and collected at a small distance such as one meter or ten meters. Data collection is ensured with a Li-Fi receiving module able to read the data and convert them for example into textual information that can be displayed on a screen, for example to transmit them to a centralized server via a wireless mobile communication link. GSM type or other. The lighting device according to the invention can be connected directly to a set of sensors such as for example a temperature sensor, a sun sensor, a hygrometric sensor, an air quality sensor, a video sensor. a pedestrian crossing sensor walking in the region of the lighting device, an automobile traffic sensor, or any other type of sensor usually installed in a city environment. This or these sensors are connected to the Li-Fi transmission module of the device, either directly or via a connector. The lighting device may be provided mainly with one or more Li-Fi interface connectors 25 to which each sensor is connected. The lighting device can thus be provided with one or more integrated and connected sensors, or simply with one or more Li-Fi transmission connectors, to which the operator of the lighting device can connect one or more sensors in order to collect the data from these sensors by Li-Fi. The transmission module Li-Fi advantageously incorporates storage means in which it records the data from each sensor, for example for a time range corresponding to the last twenty-four or forty-eight hours, or any other period such as for example the time interval separating two successive rounds. This transmission module comprises a control circuit of the illuminating portion of the luminaire, and which controls the components such as the LED components so that they flash in a given sequence, at a relatively high frequency, but not perceptible to the eye human, so as to transmit the signal comprising the data. Li-Fi data transmission is carried out by means of any modulation adapted to this type of transmission, such as NRZ-OOK modulation.
    [0007] This signal is emitted for example continuously, or during a certain predetermined time range corresponding to the beginning or the whole evening. The signal that is transmitted Li-Fi comprises a set of data comprising the data from each sensor that carries the lighting device, and optionally an identifier of the lighting device or the luminaire.
    [0008] The collection of data is ensured with a Li-Fi reception module, making it possible to convert the data transmitted in the form of textual information that can be displayed for example on a screen. Advantageously, the receiving module comprises a mobile electronic device of the tablet or smartphone type, integrating GPS location-based means and a 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 a garbage truck or any other vehicle that regularly makes tours in one or more districts of the city equipped with the lighting system according to the invention. Advantageously, the receiving module is connected by a transmission link of the mobile telephone network type, such as for example a GSM type network. During the tour with such a module, the entire acquisition is performed in a fully automated way: when the module is in the lighting field of a lighting device, it receives the Li-Fi information that it decrypts, and 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 management server by GSM transmission, or stored. The invention thus makes it possible to remotely transmit data originating from one or more elements such as sensors, in a very simple manner, and geolocated. But the lighting device according to the invention can also be connected to a data transmission network, so as to transmit via Li-Fi data that it continuously receives this network. The invention can thus be applied to the transmission of data to users equipped with Li-Fi receivers.
    [0009] The invention provides the following advantages in particular: The invention makes it possible to collect accurately and fully automated data from several sensors, while allowing to associate with each data from a sensor, the location of this sensor.
    [0010] It thus simplifies the centralized management of a pool of sensors, from a centralized database to which data from each sensor is regularly transmitted. There is no longer any ambiguity with regard to the identification and location of each lighting device controlled from the central unit.
