The invention discloses an access method, device, device and system for visible light communication, and belongs to the field of communication technology. The method includes: obtaining a neighbor's visible light domain network VPAN information, the neighbor VPAN information including information of at least one neighbor VPAN of the first VPAN, each of the neighbor's VPAN information includes the identification ID and the search information of the neighbor VPAN; the neighbor VPAN information is sent to the user device, and the neighbor VPAN information is used for the description. User equipment is used for VPAN search and access. In the embodiment of the invention, VPAN sends the acquired neighbor VPAN information to the user's device. When the user device is searching for and accessing the VPAN, the user can search and access the neighbor's VPAN information in the neighbor's VPAN information, avoiding the need for all time windows, logical channels or modulation frequency when the user's device is searched. The rate of search saves time and improves user experience.
