Recently, Chinese Academy of Sciences (CAS) has made big breakthrough in research of semiconductor lighting. They found that the light given out through LED can connect broadband network. According to experts in CAS, the secret for LED light to get wireless Internet access is that the light of LED Lights can send modulating signal through 2 million times of switch motion in every second to complete the transition of information and direction. Now the highest speed of online transmission is 2M per second, and in the future the access speed in one second can reach even 1G. Using LED Lighting for wireless Internet access is not only convenient but also safer. The electromagnetic radiation free character can allow applications mostly on the plane or under water. Whether it is applicable for household is still under research, let alone going commercial. America, Japan and Europe have started working on research of LED wireless communication technology, which might become an important direction in the future. Many countries are now developing led high bay light communication components technology. The further development is worth attention.
