With the rapid development of mobile terminal, smart home and Internet of things, lighting companies are no longer a new thing to choose communication giants and Internet giants: in May 2015, GE joined Apple high Qualcomm into the Internet lighting equipment market; in mid February 2016, the global IT giant CISCO launched the Smartcast ether with Cree. Network powered intelligent lighting platform, the Internet of attacks, CISCO has established a global partnership with PHILPS; in March 15, 2016, PHILPS hand in hand to the British telecommunications company Wo Dafeng (Vodafone), remote control intelligent street lamps; in March 18, 2016, the Internet of things lighting platform supplier Gooee and EnOcean cooperation Together to build a network Bluetooth intelligent lighting control system; in the middle of April, HUAWEI and OPPLE lighting signed a smart home cooperation agreement; in April 26th, GE's Current company spent one hundred million Australian dollars in the wireless communications, intelligent lighting industry, the famous manufacturer Daintree Networks. Through the cross-border cooperation with communications companies and Internet Co, traditional lighting enterprises make up for their own defects in networking technology, open new markets and seek business breakthroughs. Most people think that smart lighting will be the first wave of the market after the combination of the two, but it is also suggested that the cooperation between the traditional lighting companies and the Internet Co is likely to snatch the Wifi's job. As we all know, WiFi is one of the main technologies of near field communication, but in recent years, a new type of technology is also very noticeable, that is, Lifi. LiFi, also known as visible light infinite communication technology, is a kind of electromagnetic wave in essential light and radio waves. By adding a chip to control light flicker in the LED lamp, different data information can be coded according to different light rates. The receiver of the terminal of the notebook and the mobile phone can accept this data information. . That is, where there is light in the future, there is a network. The LED based Lifi can reach a data transmission rate of 10 Gb/s and can improve the upper limit of the data transmission rate of the Wifi 7 Gb/s. The rate of data transmission by laser can easily exceed 100 Gb/s. Low delay and higher transmission rate are the two advantages of Lifi. However, Lifi wants to be popularized in a large scale. It still needs many difficult problems, such as the interference of the light network communication environment, the communication distance, the correlation technology, the communication standard and so on. But the future of Lifi is still well worth looking forward to, said Ceng Yueming, chief engineer of the new tri lighting optoelectronics department, "Lifi is a subversive technology. From the point of view of energy saving, safety, transmission speed and information, Lifi is better than WiFi. Many foreign enterprises have been developing this technology. The recent cooperation between HUAWEI and OPPLE lighting in China may have a breakthrough in Lifi. "The intelligent light bulb of the Internet of things is likely to be the backbone of the Internet of things in the future," said Sheng Wenjun, chairman of tling microelectronics. Although most of the Internet of things are wirelessly connected, it will still need a backbone. In fact, there is a very suitable carrier is the lamp, the lights are everywhere, there are places where people have lights, indoor and outdoor. If each lamp can be connected, the other intelligent products around it can be connected through the MESH net of the lamp. From this point of view, it is a very meaningful thing to make an intelligent light networking first. "
