Abstract:
A visible light communication (VLC) transceiver includes a substrate, a lens module and a plurality of channel units. The channel units are disposed on the substrate in an array to provide different bidirectional communication channels. Wherein, each of the channel units respectively includes at least one light-emitting diode (LED). The LED serves as a visible light emitter in an illumination time slot, and the LED serves as a visible light receiver in a dark time slot. The channel units can enhance communication bandwidth by using modulation technology such as spatial multiplexing or time multiplexing. The lens module is disposed on an optical path of the channel units. The lens module actively tracks the receiving situation of the visible light receiver to improve the signal quality of high-speed multiplexing communication.
