Problems solved by technology

[0008] However, wires tend to emit radio frequencies, making the electrical equipment they connect to sensitive to radio frequencies
The number and length of wires required to illuminate all passengers and give them access to VLC technology makes it very complex to integrate lighting and communication systems in the cabin using VLC technology

Embodiment Construction

[0025] refer to Figure 1 to Figure 4 , the present invention is realized here in the aircraft cabin. The aircraft cabin comprises a plurality of seats 1 each intended to accommodate a passenger 2 . Each passenger 2 thus has a personal space. Each passenger 2 may be equipped with an electronic device 3 such as a laptop, smartphone, tablet, connected watch or the like.

[0026] The lighting and communication system according to the first embodiment of the invention is intended to illuminate each passenger 2 and implements VLC technology so that each passenger 2 can communicate with the computer terminal 4 of the aircraft through its electronic device 3 . Each passenger 2 can thus access various multimedia data stored in the computer terminal 4 and can also access the Internet via the computer terminal 4 .

[0027] In order to communicate with the computer terminal 4 of the aircraft, the passenger's electronic device 3 must be equipped with a VLC sending and receiving device....

Abstract

The invention relates to a lighting and communication system comprising a first optical fiber portion (31), a second optical fiber portion (32), a third optical fiber portion (33), a fourth optical fiber portion (34) and a fifth optical fiber portion (35) that are distinct, an emitter of visible light (9) being positioned at a first end of the first optical fiber portion (31), an emitter of modulated light signals (15) being positioned at a first end of the second optical fiber portion (32), a second end of the first optical fiber portion (31) and a second end of the second optical fiber portion (32) being connected to a first end of the third optical fiber portion (33), a receiver of modulated light signals (16) being positioned at a first end of the fourth optical fiber portion (34), a second end of the third optical fiber portion (33) and a second end of the fourth optical fiber portion (34) being connected to a first end of the fifth optical fiber portion (35).

Description

technical field [0001] The invention relates to the field of lighting and communication systems comprising transmitters and receivers for modulating optical signals. Background technique [0002] Lighting and communication systems are known which comprise light-emitting diode lamps (here referred to as LED lamps) and use a technology called "VLC" (Visible Light Communication). Such a lighting and communication system allows both to illuminate the environment of the LED lights, and to send and receive modulated light signals to allow wireless communication between the lighting and communication system and electronic devices located in the vicinity of the LEDs. [0003] In this type of lighting and communication system, wires are required to deliver power current to the LED lamp to drive the components provided in the LED lamp. These components include visible light transmitters (including one or more LEDs), modulated light signal transmitters (including one or more LEDs), mo...
