[Abstract] In this paper, we review the status of visible light communication and discuss research trends in this field. We suggest that illumination and communication can be achieved simultaneously, and this has the advantages of high bitrates, enhanced security, abundant spectrum resource, and no electromagnetic interference. Visible light communication will be an important part of future communication, and will greatly promote the development of information society.
