To reduce the difficulty of receiving visible light signals from mobile phone cameras, a new light-emitting diode(LED) light array visible light communication transmitting system is developed. A lamp array arrangement structure combining communication lamp and positioning lamp is innovatively proposed, and a special encoding method of frame spacing loading a full light screen is designed to ensure the illumination effect while realizing the parallel transmission of optical information, Matlab simulation software is used to simulate and analyze the lighting and communication effects of the system, and the communication effect is tested experimentally. The results show that the transmission system can meet the lighting requirement by interspersing one frame of full bright picture between two effective information transmissions, and the transmission bit error rate is low, and the communication performance is good.
