The LED electronic processing unit 100 also collects and archives this data collected by the home sensors 150. A radio channel of the communication interface 120 of the lighting 100 can for example be used for this purpose. An installation may comprise a plurality of LED lights as described with reference to FIG. 1. One of the electronic processing units 110 of one of the lights 100 will then be chosen as the master unit. This master unit can collect the data from the domestic sensors 150 and / or collect all the data collected by the other electronic processing units of the other lights. In case of failure of the master unit, another of the operational electronic processing units can be elected as the master unit according to communication methods between electronic units known per se. The data thus collected from the domestic sensors 150 are also stored in the IISD memory, in the same way as the collected power consumption data, and can be consulted by the consumer and transmitted to the outside at the request of the consumer. This data collected from the home sensors 150 can also be transmitted via the Ethernet cable 114 to an electrical panel of the housing via a telecom box 20 for further processing. The Ethernet cable 114 can also be directly connected to the electrical panel of the housing. The electrical panel comprises an electronic processing unit collecting all the data collected by a plurality of LED lights according to the invention and consolidating these data for archiving and transmission to the outside of the housing.

For example, the data collected and stored in the memory! ISD can be transmitted regularly to the electrical board via the Ethernet cable 114 and duplicated automatically in a secure electronic safe box 50 with a frequency determined according to a consumer setting.

According to one embodiment, the electronic processing unit 110 can also be parameterized to detect operating anomalies from the data collected from the home sensors 150, for example an air quality fault or an intrusion detection. The electronic processing unit 110 can also detect electrical anomalies in the operation of the lighting, for example a power supply fault on the Ethernet cable or a fault of the light-emitting diode 101 bulb. electronic processing 110 can then issue an alert to the consumer or a third party via the communication interface 120 and / or issue an audible alert via the speaker 113 and / or transmit an alert on the Ethernet cable to the electrical panel via the telecom box 20. The electrical panel to which is connected the Ethernet cable 114 supplying the lighting 100 according to the invention may have a USB port to allow an update and / or maintenance of the software of the control unit. 110 electronic processing of lighting 100.

The configuration of the electronic unit 110 can also be carried out by the consumer using a device communicating via Ethernet, Wifi or radio, via the interface 120 of the lighting 100. Such a device can be a tablet, a PC, a smartphone or other, provided with appropriate software. The LED lighting 100 according to the invention can be used to control a domestic electrical installation. Such a control includes the collection of data relating to the operation of the diode 101 and from the household sensors 150 as appropriate. The collected data may be time stamped by the electronic processing unit 110 before storage in the memory p, SD. The existing solutions, limited in usage consumption measurement points, do not make it possible to deal with the specific consumption of the lighting station, nor the comfort and the quality of well-being of the occupants of a dwelling.

If several electronic processing units 110 are involved in the collection and archiving of the sensor data, a step of choosing a master unit can be performed to coordinate the collection and archiving of the data, as well as the consultation of the data. archived and their transmission to the outside. The election of an electronic processing unit as the master unit can be done in any manner known per se. If the chosen master unit were to fail, a new election of a master unit among the operational electronic units would take place, in a manner known per se. The control of an electrical installation according to the invention also comprises the transmission and / or consultation, on request, of the collected and archived data. For example, the data collected is stored on an 11SD card directly in each of the memories of the electronic processing units of each LED lighting, for a predetermined sliding duration (a few weeks or a few months depending on the settings). This data can then be cyclically duplicated in a secure electronic safe 50 outside the housing, without limitation of duration. The transfer of these data is performed on the Ethernet cable 114 and / or by radio link or Wifi via a telecom box 20 and / or via an electrical panel. The transfer of data to the secure electronic safe 50 can be encrypted. In the case of an electrical break in the Ethernet cable, the electronic processing unit may have sufficient autonomy to save the data and send an alert to the consumer or to a third party. An automatic device can then put the sensors to sleep and interrupt data collection. Moreover, the autonomous power source 115 makes it possible to ensure degraded operation. The consumer may also require, by means of a communicating device provided with appropriate software (Smartphone 30 for example, PC or other), to consult the data stored in the memory of the lighting or in the memory of the electrical panel which centralizes a set of data collected by several lights according to the invention. The data collected by each LED lighting according to the invention can be processed and formatted in order to allow the establishment of custom added value services. The current measurements of each diode 101 collect detailed consumption information. This information allows consumers to become aware of, manage and optimize their energy consumption in their home and have access to a detailed report of their electricity consumption (just like a telecommunication bill or a bill of exchange). monthly bank statement of his transactions).

Existing solutions centralize information on external servers controlled by energy providers to create service platforms: they are intrusive solutions where the consumer does not have the control of his data. The control of an electrical installation according to the invention also includes the monitoring of the collected data to detect operating anomalies and the issuance of an alert in the event of a detected anomaly. The electronic processing unit can be parameterized to detect anomalies in the data collected from the domestic sensors or anomalies in the operation of the light-emitting diode. It can then send alerts to the consumer or to a third party set on triggering events that can be: a PoE power failure, a defect of the LED bulb, the triggering of an intrusion alarm, a defect of air quality, temperature, humidity, water leakage ... inactivity alert (monitoring of an elderly person for example). Existing solutions do not address electrical safety and are still limited in the treatment of the environmental quality of a home. In the event of a total loss of the PoE power supply with a battery run, a first message may be sent to one of the consumer's interfaces and a second message may be sent to the electrical panel of the housing and / or to the other lights according to the invention if present in the housing. The consumer can thus manage in a personalized way his uses of electric lighting and keep in a secure way a history of data related to the lighting in his dwelling. The invention has been described with reference to particular embodiments that are not limiting. In particular, the number and nature of the sensors may vary according to the applications, as well as the modes of transmission and consultation of the collected data.
