摘　　要：为了兼顾室内照明和通信,实现可见光通信系统的商用化,设计了一套基于大功率白光LED的可见光通信系统。采用OOK调制将交流信号加载到10W的LED灯上,搭建了采用串联驱动方式的发送电路和带宽为20M的接收电路。For interior lighting and communications, also to realize the commercialization of the visible light communication system, the paper designs a high-power LED drive transmission circuit and the receiving cir- cuit with a gain bandwidth. To load an AC signal on the 10W LED lamps by the OOK modulation mode, the paper designs a transmission circuit with tandem drive mode and have built the receiving circuit with a band- width of 20M.
