Abstract
Multifunctional LED devices and multifunctional LED wireless conference systems are provided. A multifunctional LED device includes LED light source assembly, LED drive and power supply unit, controller unit, audio power amplifier unit, microphone module, wireless transceiver module, speaker unit, and/or audio codec unit. The wireless transceiver module is configured to communicate with each of a smart terminal and a second multifunctional LED device. A multifunctional LED wireless conference system includes at least two multifunctional LED devices and at least one smart terminal to read status of and to remotely control the at least two multifunctional LED devices. The smart terminal communicates with outside terminal(s) to send audio signals from the outside terminal(s) to the multifunctional LED device(s) for broadcasting. Meanwhile, the multifunctional LED devices collect ambient sound and send the ambient sound to the outside terminals via the smart terminal so that wireless conference function can be achieved.
