Description

Emergency lighting system

Background of the invention

The invention relates to a bulb and a system for providing emergency lighting in an environment when the main lighting of this environment is faulty.

WO 2014/179531 discloses a system for providing emergency lighting. This system has a major disadvantage in that it generates an electrical over-consumption and a radio-frequency pollution.

The invention finds a preferred but non-limiting application in a general public environment. It aims a simple solution to implement to provide different points of light, each providing sufficient light to allow an individual to orient in his environment and does not have the disadvantages of the prior art. Object and summary of the invention

More specifically, the invention relates to a lighting system comprising:

- An electrical box connected to a power distribution network, via an electrical panel, the housing comprising an identifier, a battery, at least one LED, battery charging means and wireless communication means;

a network comprising at least one light bulb, each light bulb comprising an identifier, at least one LED, a battery, means for recharging this battery, and wireless communication means, each light bulb being controlled by a switch and powered by the electricity distribution network in a so-called "normal" operating mode;

- the bulbs and the electrical box being matched by means of their identifiers; the electrical box being able to send, by its wireless communication means, an emergency ignition command to the bulbs with which it is matched when it detects a cut in the electricity distribution network upstream of the switchboard electrical ampoules within range of the housing being able to relay this command to the bulbs of said network and which are out of reach of the communication means of the electrical box;

- Each bulb being adapted, on detection of a power failure from the electrical panel, to switch to a mode called "waiting for control" to temporarily power its wireless communication module from its battery and upon receipt of the emergency ignition command to turn on at least one of said LEDs from said battery in a so-called "backup" mode.

The lighting system according to the invention thus provides emergency lighting in the event of a break in the electricity distribution network upstream of the electrical panel.

According to the invention, as long as the electrical panel does not detect a power failure (in other words, as long as the sector is present), it does not send any command or signal.

Thanks to these advantageous characteristics, the system of the invention consumes less electricity than that described in the aforementioned document of the prior art, and does not cause any electromagnetic disturbance in mains operation mode (excluding cut detection).

In a particular embodiment, the battery of the electrical panel is electronically isolated from the rest of the electronics of this housing, for example by a transistor or relay, the electronics of the electrical box being powered by the battery only in case of failure current upstream of this array.

In a particular embodiment, the detection of the cutoff of the electricity distribution network is performed when the electrical box becomes powered by the battery.

According to the invention, when a bulb detects a power failure, it switches to standby mode. emergency ignition control, temporarily powering its wireless communication module from its battery.

It is understood that the bulb will receive such a control of the housing in case of detection of power failure by the housing, but that it will not receive a command if the power failure at the level of the 'bulb comes from a normal action of the user at the wall switch controlling this bulb.

Therefore, in accordance with the invention, the switch to emergency mode is performed only in case of failure upstream of the electrical panel.

In a particular embodiment, the electrical box is installed between the differential 30mA and the fuses / switches that protect the household power supply. In this embodiment, the switching of a switch / fuse downstream of the electrical box does not trigger sending emergency ignition command so that the bulbs do not go into emergency mode.

The system according to the invention is also remarkable in that it makes it possible to constitute a closed network, the network being able to be constituted progressively and easily by means of the pairing mechanism, the relay mechanism possibly making it possible to install emergency light bulbs out of scope of the electrical box.

In one embodiment, the system according to the invention comprises means for implementing a procedure for pairing the bulbs with the electrical box, the procedure for pairing a bulb having the connection of the bulb on a socket connected to the electrical network, the selection of a pairing mode at the electrical box, the execution of a predetermined sequence of ignition and extinction of the bulb by means of a switch associated with this bulb, and the exchange of their respective identifiers by the electrical box and the bulb.

This pairing procedure is very simple to implement; it has the advantage of being able to be executed without particular knowledge of the user, without additional hardware and without requiring the entry of the identifiers of the bulbs or the housing. In a particular embodiment, the bulbs and / or said electrical box include means for implementing a charge management mechanism of their batteries to avoid overcharging and / or overheating of these batteries.

In a particular embodiment, a light bulb leaves the emergency mode and switches to a so-called "sleep mode" in which said battery stops supplying the wireless communication module and the LEDs when the voltage at the terminals of this battery becomes less than a predetermined value.

These two particular embodiments aim to preserve the life of the batteries and the degradation of their performance over time.

In a particular embodiment, the electrical box includes LED lighting that can be powered by the battery of the housing.

This embodiment allows the user to obtain additional emergency lighting near the electrical panel.

In a particular embodiment, the system according to the invention further comprises a terminal adapted to communicate with the electrical box for controlling and / or managing a state of each of said bulbs.

For example, in a particular embodiment, a bulb is able to send information on its state to the electrical box, this information being transmitted by said electrical box to the user's terminal.

The terminal can also be used to individually control the lighting power of the bulbs via said electrical box, when the bulbs are in said normal operating mode.

The invention also relates to a bulb and an electrical box that can be used in a system as mentioned above.

More specifically, the invention relates to a light bulb comprising an identifier, at least one LED, a battery, battery recharging means, wireless communication means, this lamp can be controlled by a switch and powered by a network of distribution of electricity in a so-called "normal" operating mode, this bulb can be matched by means of its identifier to an electrical box connected to this electricity distribution network. According to the invention, this bulb is adapted to receive, by its wireless communication means, an emergency ignition command from the electrical box with which it is matched when this unit detects a cutoff of the distribution network of electricity upstream of the electrical panel and to relay this command to the bulbs of the network which are out of range of the electrical box.

According to the invention, this bulb is adapted, on detection of a power failure from the electrical panel, to switch to a mode called "waiting for control" to temporarily power its wireless communication module from its battery and, upon receipt of such a backup ignition command to turn on at least one of said LEDs from the battery in a mode called "emergency".

The invention also relates to an electrical box, connected to an electricity distribution network, via an electrical board, this box comprising an identifier, a battery, charging means for this battery and wireless communication means, this box electrical device that can be matched by means of its identifier to at least one bulb of a network, the electrical box optionally comprising an LED and being able to send, by its wireless communication means, a backup ignition command to the bulbs with which it is matched when it detects a cut of the distribution network of electricity upstream of the electric board.

Detailed description of a first embodiment of the invention

Figure 1 shows a system 1 according to a particular embodiment of the invention. This system comprises an electrical box 100 and a network R of bulbs 10, each controlled by a not shown wall switch. Of course the network can be limited to a single bulb.

In the embodiment described here, the system R further comprises a terminal 300 capable of communicating with the electrical box 100. This terminal 300 may for example be constituted by a laptop, a tablet or a smart phone. It has an APP system management application.

The electrical box 100 is connected to an electrical panel 200, for example to a standard DIN rail of this table. The electrical panel 200 is connected to the electricity distribution network or electrical network 2; it is not modified by the invention.

The electrical box 100 is preferably installed between the 30mA differential and the fuses / switches that protect the household power supply.

In a general manner, the electrical box 100 is adapted to send an emergency ignition command (either directly or by relay) to the bulbs of the network when it detects a failure of the electrical network 2.

In the embodiment described here, the electrical box 100 includes a mode of operation called "voluntary cut" in which the emergency ignition command is not sent. This mode can in particular be used when the user leaves the premises for a long time, for example during a period of leave, to preserve the batteries on board bulbs. Entry into the voluntary cutting mode is performed by means of a CV voluntary cut button present on the housing 100.

In the embodiment described here, the electrical box 100 comprises a processor CPU and a non-volatile memory MEMB in which is stored a BID identifier of this housing.

The electrical box 100 includes a battery 120. This battery can for example be constituted by a high temperature battery of size AAA, AA or A.

In the particular embodiment described here, the battery 120 is electronically isolated from the rest of the electronics of this housing by a transistor, not shown. The electronics of the electrical box is powered by the battery 120 only in the event of a power failure upstream of the electrical panel 200. According to the invention, the electrical box 100 is able to communicate via a wireless communication link with the bulbs. 10. The electrical box 100 and each of the bulbs 10 comprise for this purpose a communication module COM, all these modules being compatible.

These communication modules in particular allow the electrical box 100 to send an emergency ignition command to the bulbs 10 within range when it detects a power failure, and these same bulbs 10 to relay this command to the other bulbs of the network out of range of the electrical box 100.

In the embodiment described here, the housing 100 comprises an LED lighting 130 that can be powered by the battery 120.

The CPU processor of the electrical box 100 is able to execute the instructions of a PGB computer program stored in the MEMB memory and whose main steps will be described in FIGS. 2A and 2B.

In the embodiment described here, the housing 100 includes a switch 150 controllable by the processor CPU for connecting the battery 120 to the mains 2 when it is to be recharged. This switch can be constituted by a transistor.

The bulbs 10 can be installed on standard sockets. They comprise one or more LEDs 11, a battery 12, and a communication module COM already mentioned. In the embodiment described here, a bulb 10 comprises a CPU processor and a non-volatile memory MEMA in which is memorized an identifier AID of this bulb.

A default value of this identifier is set by the manufacturer; in the embodiment described here, this identifier may optionally be modified by the user by means of the APP application of its terminal 300 so as to give it a more explicit name, for example according to the location of the light bulb in the building ("living room", "kitchen", "office", "cellar" ...).

The battery 12 of the bulbs 10 may for example be constituted by a high temperature battery type AAA, AA or A.

In the embodiment described here, the bulb 10 comprises a switch 15 controllable by the processor CPU for charging or not the battery 12 when the light bulb is connected to the sector. This switch can be constituted by a transistor.

The CPU processor of the bulb 10 is able to execute the instructions of a PGA computer program stored in the memory MEMA and whose main steps will be described with reference to FIGS. 3A and 3B.

At the first installation of the system, it is necessary to constitute the network R of bulbs. This operation consists in pairing the bulbs 10 with the electrical box 100.

The procedure for pairing a bulb 10 with the electrical box 100 consists, in the embodiment described here, to connect the bulb 10 to a standard socket connected to the mains, to select the pairing mode at the housing electrical 100 (an AP button may be provided for this purpose), and play a predetermined sequence of ignition and extinction of the bulb 10 by means of the associated wall switch.

The electrical box 100 and the bulb 10 can thus exchange and store their respective identifiers BID, AID.

Following this pairing, a light bulb 10 of the network R accepts the commands of the electrical box 100 BID ID, and the electrical panel 100 knows the identifiers of the bulbs to which it must send the emergency ignition commands in case of cut-off of the electricity network 2 upstream of the electrical panel 200. In the embodiment described here, the bulb 10 automatically returns to normal mode on receipt of a message from the electrical box 100, this message being representative of the smooth running of the pairing procedure.

With reference to FIG. 2A, we will now describe the main steps of the method implemented by the box 100 to manage the charge of the battery 120.

The electrical box 100 is connected to the electrical panel 200 and thus benefits from a permanent power supply via the electricity grid 2. However, in a preferred embodiment, it avoids the overcharging of the battery 120 so as not to damage or degrade its performance.

In the embodiment described here, the system according to the invention allows charging of the battery 120 of the electrical box 100 in a continuous mode (at the first use of the system, after a backup period, or after a long period of no recharging) and in an intermittent mode as soon as the charge of the battery 120 becomes lower than a predetermined threshold.

More specifically in the embodiment described here, noting CB the maximum capacity of the battery 120:

in continuous mode, the battery is charged at CB / 10 for 15 hours; and

- In intermittent mode, charge the battery at CB / 10 for 4 hours.

At the first use, during a step B10, the switch 150 is controlled to enable charging the battery 120 in continuous mode, namely with an initial charging CB / 10 for 15 hours.

The battery 120 then discharges normally.

During a general step B20, the processor CPU periodically measures the voltage of the battery 120. If the empty voltage of the battery goes below a threshold (for example 1.3V), the battery is recharged intermittently (ie a CB / 10 charge for 4 hours) (step B30).

In the embodiment described here, if the voltage of the battery does not fall below this threshold for a long period of no recharging (by example 15 days), it is also recharged in intermittent mode, namely with a CB / 10 charge for 4 hours (step B40).

In the embodiment described here, if the system was used in rescue mode:

the battery 120 is loaded in continuous mode, namely in this example with a load of CB / 10 for 15 hours, for example when its voltage drops below a second threshold (for example 1.2V) (step B50 );

the battery 120 is charged in intermittent mode, namely in this example with a charge of CB / 10 for 4 hours if its voltage remains higher than this second threshold (step B55).

In the embodiment described here, the CPU maintains a counter C in its MEMB memory to account for:

- the charging time (15 hours or 4 hours in this example); and

- the period of no recharge (15 days in this example).

Referring to Figure 3A, we will now describe the main steps of the process implemented by the processor of the bulb 10 to manage the battery 12, so as to avoid an overload that could be detrimental to its life or to its performance and to allow recharging of the battery in a relatively short time.

The bulb 10 has in this example four modes of operation:

a so-called "normal" mode in which the bulb 10 is powered by the electrical network 2 on command of the associated wall switch;

an "emergency" mode in which the bulb 10 is powered by the battery 12 on receipt of an emergency ignition command received from the electrical box 10;

a "command waiting" mode in which the bulb 10 is not powered but maintains for a short period (a few seconds) a power supply of its communication module to possibly receive a backup ignition command from electrical box 100; and - A "sleep" mode in which the bulb 10 is not powered by the power grid 2 and reduces its consumption to the maximum to limit the discharge of the battery 12 ..

Note that the bulb 10 is configured to switch from standby mode to sleep mode when the battery 12 is almost completely discharged (eg voltage less than IV).

The battery 12 of the bulb 10 is recharged only when the bulb 10 is on is in normal operating mode.

In the embodiment described here, noting CA the maximum capacity of the battery 12:

in the initial charging mode, the battery 12 is charged with a charge of 0.5 AC, until at least one end of charge condition, explained below, is detected; and

- In charge holding mode, the battery 12 is charged to 0.5 CA when the voltage measured at these terminals is less than a threshold value, for example 1.3V, until at least one end of charge condition is detected.

In the embodiment described here, an end of charge condition of the battery 12 is the -A (V) test known to those skilled in the battery industry, this test corresponding to the detection of a voltage drop in end of charging period.

For safety, it is also possible to use another end of charge condition associated with a time counter C to stop the charging of the battery 12 if the end of charge condition -A (V) is not detected.

This time counter measures the cumulative charging time of the battery 12; the end of charge condition can for example be detected when the counter C reaches:

- 2.6 hours in the initial charging mode (AC x 130% / 0.5 x AC = 2.6, where 130% corresponds to the battery charge efficiency);

- 0.5 hours (for example) in load holding mode.

When the end of charge condition is detected (either by -A (V) or by expiry of counter C), counter C is reset to 0.

Furthermore, in this embodiment, the processor CPU of the bulb 10 makes sure not to charge the battery 12 if the temperature of this battery is greater than a cut-off temperature TC (for example 60 ° C) so as not to damage it or degrade its performance. When the processor CPU of the bulb 10 identifies verifies that the temperature of the battery 12 is greater than this cutoff temperature TC, it does not start or interrupts the charge.

An identical mechanism may optionally be implemented to protect the battery 120 of the electrical box 100 from overheating.

Steps A5 to A50 described below are executed only if the bulb 10 is in normal operating mode, that is to say powered by the electrical network 2.

The batteries 12 will be delivered by the manufacturer with a residual AC load typically 40 to 60% and the bulb will not be able to assume a backup function for the maximum possible time with a fully charged battery.

When the bulb 10 is turned on, the CPU processor first checks during a preliminary step A5 that the temperature of the battery 12 is not greater than the cut-off temperature TC.

The CPU processor then starts charging the battery 12 in the initial charging mode with a charge of 0.5. CA (step A10) until one of the end of charge conditions is detected (step A20)

During a general step A25, the processor CPU regularly measures the voltage of the battery 12. If the voltage of the battery goes below a threshold (for example 1.3V), the battery temperature being lower than the temperature of the battery cut T, the battery is recharged in charge holding mode (ie 0.5.CA load) until one of the end of charge conditions is detected (step A30).

In the embodiment described here, if the voltage of the battery does not fall below this threshold for a long period of non-recharging (for example 15 days) (test A40), it returns to charge maintenance mode. If the bulb has been used in emergency mode (test A50) it is recharged in the initial charging mode (return to step A10).

Steps A40 and A50 are similar to steps B40 and B50 already described.

In normal operating mode, the lighting and extinction of the bulb 10 is done by a wall switch of the room, conventionally. The electrical box 100 and the bulb 10 implement the methods described with reference to Figures 2A and 3A to charge the batteries 120 and 12 and protect them from overcharging and overheating.

A wall switch can turn on and off the bulb 10 We will now describe with reference to Figures 2B and 3B an example of implementation of an emergency procedure within the meaning of the invention.

When the bulb 10 is turned on, in normal mode, it is powered by the electrical network 2 and its battery 12 is never solicited discharge.

When the electrical box 100 detects a cutoff of the electrical network 2 (step B100), it verifies (step B150) that it is not in the voluntary cutoff mode and then sends to the bulbs 10 of its network, identified during the procedure of pairing, an emergency ignition SEC instruction (step B200). In the embodiment described here, the electrical box also turns on its LED lighting 130 through the battery 120 to facilitate in the dark the intervention of the user on the electrical panel 200.

When the processor CPU of the bulb 10 detects an interruption of the power supply (step A100), it temporarily supplies (step A200) the wireless communication module COM with the battery 12 to receive (step A300) the control of SEC emergency ignition sent by the electrical box 100 in case of mains failure upstream of the electrical panel 200.

In case of extinction by the wall switch, the electrical box 100 does not send emergency ignition command and the bulb enters sleep mode (step A500). The processor of the bulb 10 stops the power supply of the communication module COM.

When the bulb 10 receives the emergency ignition command SEC, it checks that it comes from the electrical box 100 with which it was paired, then switches to emergency mode (A400).

In the embodiment described here, the bulb 10 relays the emergency ignition command SEC to the other bulbs 10 belonging to the network and which are out of range of the electrical box 100 (step A350). In the emergency mode, the bulb 10 turns on in degraded mode, one or only some of the LEDs 11 being powered by the battery 12.

As soon as the sector is restored (test A100), the bulb 10 returns to the normal mode (step A150) and its battery 12 is recharged.

In the embodiment described here, the bulb 10 remains in the emergency mode as long as the voltage across its battery 12 remains higher than a predetermined value, for example IVolt for a Ni-MH battery or 2.75V for a battery. Lithium-ion battery (A600 test). These parameters make it possible to limit the depth of discharge of the battery and thus prevent its rapid aging due to frequent deep discharges. This end-of-discharge protection system preserves the performance of the battery over time.

When the voltage across the battery 12 becomes lower than this voltage (test A600) the bulb 10 enters the sleep mode (step A500).

In the embodiment described here, each bulb 10 of the network R communicates (either directly or by relay) status information to the electrical box 100 (state of charge, if on, temperature, battery voltage, light-on time). 24 hours, etc.), this information being transmitted by the electrical box 100 to the APP application of the terminal 300.

The user can thus monitor the entire network R.

In a particular embodiment, the APP application of the terminal 300 can make it possible to control individually the lighting power of the bulbs 10 of the network R, via the electrical box 100, when they are in normal operating mode, in other words powered by the electricity network 2.

The APP application can also be used to program the on, off or light power of the R-array bulbs in a user-defined sequence or scenario. These scenarios notably allow:

- to simulate a presence;

- Gradually lower the intensity of the lighting in a child's room; - to light, especially for the use of the hearing impaired, a light bulb on detection of a fire or the ringing of the telephone.

The invention has been described with bulbs but applies identically with neon, fluorescent or compact fluorescent tubes.

DETAILED DESCRIPTION OF A SECOND EMBODIMENT OF THE INVENTION

Referring to Figure 4, we will now describe a system according to a second embodiment of the invention.

In this embodiment, the bulbs are connected directly to the electrical panel 200 (without switch) but they include a driver 19 of LEDs (English driver) to turn on or off at least one of their LEDs on receipt of a control command . In other words, although supplied with electricity, a piloting control makes it possible to extinguish these bulbs or to vary their lighting intensity by switching on one or more LEDs 11.

In this embodiment, the system comprises at least one switch 1000 also directly connected to the electrical panel 200, this switch comprising a processor, a non-volatile memory MEMS in which is stored a computer program PGS and identifier SID, a battery 1012, means for recharging said battery, and wireless communication means.

Each of its switches is matched with one or more bulbs 10 so as to form subnets.

In this embodiment, when the electrical box 100 detects a cut in the electricity distribution network upstream of said electrical panel 200, it sends the emergency ignition command to the bulbs 10 with which it is paired but also to switches 1000.

In this embodiment, the switches 1000, like the bulbs 10, switch to the "command wait" mode to temporarily power their wireless communication module from its battery 1012 when they detect a break in the power supply. In the embodiment described herein, and as described with reference to the first embodiment, the bulbs 10 are configured at the factory outlet to light when they receive the emergency ignition command from the electrical box. They can nevertheless be configured differently by the terminal 300.

According to the embodiment described here, when the switch 1000 has received the emergency ignition command from the electrical box 100, and it has gone into emergency mode, it is able to send a control command of bulb lighting to which it is paired to the user's order. This control command is determined according to a mode selected by the switch ("switch off bulb", "dimmed lighting", "bright lighting", ...) and contains a parameter interpretable by the bulb to turn off all LEDs from the bulb or to turn on at least one.

In a particular embodiment, the switches are configured to broadcast the emergency ignition commands received from the electrical box 100 to the other switches and the bulbs of the network. When a switch or light bulb receives such a command, it goes into emergency mode only if it is paired to the electrical box at the origin of this command.

In a particular embodiment, the bulbs are configured to broadcast the control commands received from a switch to the other bulbs of the network. When a bulb receives such a command, it responds only if it is paired to the switch causing this command.

In a preferred embodiment, the switch 1000 comprises a touch interface 1013 to allow this selection.

The processor 12 of the bulb 10 controls the driver 19 to turn on or off the LEDs 11 of the bulb according to this control command.

In the embodiment described here, the switches 1000 also include an LED 11 forming a pilot light.

The second embodiment of the invention has several advantages:

1 / Because the bulbs 10 are permanently powered, because connected directly to the electrical panel 200, they can all pass in control standby mode to receive a backup ignition command to go into emergency mode when the electrical box 100 detects a failure upstream of the electrical panel 200.

2 / Moreover, the bulbs 10 being permanently powered, their batteries 12 are recharged to the maximum so that their period of operation in emergency mode is extended.

This second embodiment of the invention is particularly suitable for new electrical installations in which the bulbs are controlled by switches provided with wireless telecommunication means, without wiring between the bulbs and these switches.

This second embodiment, like the first embodiment described above makes it possible to differentiate the power supply interruptions due to a power failure of the voluntary requests for extinguishing the bulbs by the user according to whether the bulbs receive the control of emergency ignition from the electrical box.

The appearance of the bulbs with a switch and the apparaige a switch with the electrical box can be done as apparaige between the electrical box and the bulbs in the first embodiment of the invention: predetermined ignition sequences and switching off the switch, entering identifiers at the box or switches or via the terminal 300.

More specifically, the procedure for pairing a switch 1000 with the electrical box 100 may be to connect the switch 1000 to the mains, to select the pairing mode at the electrical box 100 (a button AP may be provided for this purpose), and to select the pairing mode at the switch 1000 or through the menu accessible via the touch screen of the switch 1000 or through a button AP provided for this purpose on the switch 1000.

The electrical box 100 and the switch 1000 can thus exchange and store their respective identifiers BID, IID.

Following this pairing, a switch 1000 of the network R only accepts the commands of the electrical box 100 ID BID, and the electrical panel 100 knows the identifiers of the switches to which it must send the emergency ignition commands in the event of a cut in the electricity network 2 upstream of the electrical panel 200.

The procedure for pairing a bulb 10 with the switch 1000 consists, in the embodiment described here, of connecting the bulb 10 to a standard socket connected to the mains, and to select the pairing mode at the level the switch 1000 is through the menu accessible via the touch screen of the switch 1000 or through an AP button provided for this purpose on the switch 1000.

In the case of the selection of the pairing mode through the menu accessible via the touch screen of the switch 1000 simply enter the AID identifier of the bulb 10 through the touch screen of the switch 1000 .

The switch 1000 and the bulb 10 can thus exchange and store their respective identifiers IID and AID but also allow the bulb 10 to store the identifier of the electrical box 100 BID, previously stored by the switch 1000. The bulb 10 recognizing the identifier of the electrical box 100 still in pairing mode transmits to the latter its AID identifier that the electrical box 100 stores as part of its general private network. The switch 1000 transmits to the electrical box 100 the identifier AID of the bulb 10 to which it is matched and that it can drive on and off. The electrical box 100 stores the identifier IID of the switch 1000 and the identifier AID of the bulb 10 at which the switch 1000 is paired as part of a subnet of its general network. The electrical box 100 confirms the switch 1000 ID IID good storage of the identifier AID of the bulb 10 as part of the subnet controlled by the switch 1000 ID IID.

The default values of this group of identifiers defining this subnet are set by the manufacturer; in the embodiment described here, this group of identifiers may possibly be modified by the user by means of the APP application of its terminal 300 so as to give it a more explicit name, for example depending on the location of the the bulb in the building ("living room network", "kitchen network", "office network", "cellar network" ...). As a result of this pairing, a light bulb 10 of the network R accepts the commands only from the electrical box 100 of identifier BID and of the switch SID identifier 1000 to which it is specifically matched, and the electrical box 100 knows the identifiers of the light bulbs and switches to which it must send the emergency ignition commands in case of power mains failure 2 upstream of the electrical panel 200.

In the embodiment described here, the bulb 10 automatically returns to normal mode on receipt of a message from the electrical box 100 and representative of the smooth running of the pairing procedure.

In the embodiment described here, the switch 1000 returns to normal mode when the user exits the pairing mode through the menu accessible via the touch screen of the switch 1000.
