Visible light communication based bridging system

[0022] like figure 2 , the present invention discloses a visible light distributed system for bridging through visible light. The LED optical access point 21 accesses the Internet through a broadband access device 27. The LED optical access point 21 is set to the optical access mode, and the LED optical access point 22 and 23 are set to optical bridge mode. The LED light access point 21 bridges the visible light and LED light access points 22 and 23 to expand its coverage. The device 24 directly communicates with the LED light access point 21 through visible light, and then connects to the Internet; the device 25 and the device 26 respectively connect to the LED light access points 22 and 23 through visible light, and the LED light access points 22 and 23 serve as LED light access points. The relay of entry point 21 enables device 25 and device 26 to also connect to the Internet.
