The photodetectors 152 of the light communication module 150 are preferentially distributed along a regular two-dimensional network, a distance between two adjacent photodetectors 152 being constant.
- the photodetectors are mixed with the light-emitting diodes 1511, so that a light-emitting diode 1511 is always associated with a photodetector 152.
- each photoreceptor 152 is located adjacent and alternating with one of the photodetectors 1511.
- light-emitting diodes 1511 of the light-communication module 151 This configuration makes it possible to improve the detection of a light signal coming from any direction around the diving mask 10, thus facilitating the establishment of bidirectional communication between two masks 10 together forming a marine communication system.
- the plurality of light emitting diodes 1511 collectively forming said light source 151 of the light communication module 150 is located on a communication surface 156 which surrounds the visor 130 of the diving mask 10.
- the light communication module 150 of the diving mask 10 is located on the peripheral frame 110, the communication surface 156 forming a closed contour around the visor 130.
- the communication surface 156 can form an open contour on only part of the peripheral frame 110.
- the communication surface 156 may be located on each lateral edge of the peripheral frame 110 and / or on an upper edge and / or an inner edge of said peripheral frame 110.
- the light communication module 150 of the diving mask 10 is located on the visor 130 of the diving mask, the communication surface 156 forming a closed contour at a peripheral zone of said visor 130.
- the communication surface 156 may form an open contour on only a part of the peripheral zone of the visor 130.
- the surface of communication 156 may be located on each lateral edge of the visor 130 and / or on an upper edge and / or an inner edge of said visor 130.
- the light-emitting diodes 1511 of the light-transmitting module 150 are preferably distributed over the communication surface 156 in a regular two-dimensional array, a distance between two adjacent LEDs 1511 being constant.
- This advantageous configuration makes it possible to emit a light signal in a plurality of directions all around the diving mask 10, thereby improving the chances that this light signal will be received by a compatible photodetector by another diving mask 10 for example.
- the light communication module 150 of the dive mask 10 illustrated in FIG. 2 comprises a plurality of photodetectors 152 situated on the communication surface 156.
- the photodetectors 152 of the light communication module 150 are preferentially distributed according to a regular two-dimensional network. a distance between two adjacent photodetectors 152 being constant.
- the photodetectors are mixed with the light-emitting diodes 1511, so that a light-emitting diode 1511 is always associated with a photodetector 152.
- each photoreceptor 152 is located adjacent and alternating with one of the photodetectors 1511.
- light-emitting diodes 1511 of the light-communication module 151 This configuration makes it possible to improve the detection of a light signal coming from any direction around the diving mask 10, thus facilitating the establishment of bidirectional communication between two masks 10 together forming a marine communication system.
- the loudspeakers 154, the microphone 157, the light source 151 and the photodetector 152 are electrically connected preferentially by a wired connection to the control electronic card 156 in order to enable bidirectional light communication as described above.
- the electronic control board 156 of the light-communication module 150 is configured to drive all the light-emitting diodes 1511 in parallel and / or in a synchronized manner: thus the control system telecommunication 190 of the diving mask 10 sends, in a plurality of communication directions around said diving mask 10, a light signal which carries the same information: that which has been coded by the electronic control card 156.
- the telecommunication system 190 of the diving mask 10 can advantageously comprise a power source not shown in FIGS. 1 and 2, which can take the form, for example, of a battery attached to the diving mask 10.
- FIG. 3 illustrates an exemplary embodiment of a method 200 of marine light communication according to the second aspect of the invention.
- a method 200 of marine light communication can advantageously be implemented by the diving mask 10 according to the first aspect of the invention and as illustrated above with regard to FIGURES 1 and 2 in particular.
- the method 200 of marine light communication comprises the following steps:
- step 205 of decoding the light signal into a decoded digital signal the decoding step being performed by the electronic control board 156 of telecommunication system 190; - a step 206 of generating a sound signal via one or more speakers 154 of telecommunication system 190.
- the invention relates to a diving mask 10 comprising a telecommunication system 190 configured to allow the establishment of unidirectional or bidirectional light communication, and more particularly according to a communication protocol type LIFI.
- the telecommunication system 190 comprises a light communication module 150 comprising a light source 151 configured to emit light signals in a plurality of directions around the diving mask 10, and an electronic control card 156 to control said light source 151 and in order to modulate the amplitude of said light signal as a function of an electronic signal encoded by said electronic control card 156.
