Visible Light Communication is Going to Change the Lives of People

With the popularization of LED light, experts suggest that using the LED light to transmit data. This suggestion is based on the theory of visible light communication which is short for VLC. Every LED light can be connected into the main network, implementing the wireless communication of every device in the room without adding the burden to the crowded broadband. Governments in different countries also support the manufacturers and organizations to study the visible light communication. The turnover of traditional illumination market has already reached multi-billion and the transmission of this industry has begun; therefore, the visible light communication has large market potential. The turnover of LED light market can reach a billion in 2010, and it will increase to seven billion and three hundred million in the year of 2014 predicted by strategies unlimited company.

The power consumption of the LED light is less than the tradition light, which is always the key of solid-state illumination. However, the large market has already attracted every electric research organization to invest in the study of visible light communication. Most of the new technology is utilized in the occasions where the radio frequency wireless communication can not apply, such as the hospital and airplane. The usage of radio frequency wireless communication in such occasions may disturb the other devices which are related to lives of people. The Japanese alliance of visible light communication advocates the purpose that illumination first and communication second. The visible light is the only signal which can be seen by people so far; therefore, it is not suitable to be the remote controller. People do not want to see the glimmer while they are watching TV in a dim room.

The innovation may create a series of new application. Although the Wi-Fi and infrared can also be used in some places, the LED light is safer and more convenience. For example, the disturbance of neighboring signal will limit the utilization of Wi-Fi, while the visible light can across between each other with the different destination. The American science foundation also adds the VLC research to the intelligent lighting engineering research centre. The scientists are studying every aspects of the LED light, such as the color, density, and source. They also try to find out more value of the LED light to provide more opportunities to people. The related integrated circuit of VLC is LM2575T.
