Li-Fi is a new wireless transmission technology that uses visible light spectrum (such as light from a light bulb) for data transmission. Simply put, it is to use fiber to achieve wireless Internet access. Recently, Alexandre Picciotto, a graduate student of the Lausanne State Art Institute (ECAL) in Switzerland, collaborated with Oledcomm, a French company of optical communication (Li-Fi), to design a Li-Fi table lamp, which is ideal for placement in a library or classroom. With fiber coverage, your phone or laptop can be wirelessly connected like Wi-Fi. It is understood that this desk lamp can use the invisible infrared technology to realize Li-Fi connection even when it is turned off, so that you can connect to the Internet without turning on the light.
