In collaboration with French manufacturers, a Swiss graduate student designed the Li-Fi lamp

Alexandre Picciotto, a graduate student at the Lausanne State Institute of Art (ECAL) in Switzerland, worked with the French wireless optical communications (Li-Fi) OLEDcomm to design a Li-Fi desk lamp for the library, which could transmit files through visible light waves to a device with encrypted soft pieces.

The set of lamp is also equipped with an infrared emitter, and can also transmit files through invisible light. Even if the light goes out, Li-Fi can be used. This Li-Fi desk lamp is made of aluminum, with the Plexiglass Satinice diffuser's average dispersed light source, and each set of desk lamps has 4 hot spots.

Picciotto points out that the shape of the diffuser is designed to want light and Li-Fi networks to cover the whole desktop. Because the existing Wi-Fi radio bandwidth is limited, the speed and security are not as good as Li-Fi. Picciotto believes that Li-Fi has a hundred times faster than Wi-Fi, plus light Bobbi radio wave range, so Li-Fi has a chance to solve Wi-Fi's existing problems.

However, at present, Li-Fi technology still has difficulties, including the inability to cross walls, outdoor use will be disturbed by the sun and other shortcomings, so the application is not available at present. In the future, with the gradual popularization of the concept of Intelligent City, it is possible to apply Li-Fi to daily life through the light of street lamps or mass transit vehicles.
