A multi-channel and feedback-controlled light apparatus has a transmitter unit and a receiver unit. The transmitter unit sends out a wireless signal through at least one channel to the receiver unit. When the receiver unit receives the wireless signal, the receiver unit correspondingly sends a response signal back to the transmitter unit. If the transmitter unit does not receive the response signal, the transmitter unit will switch to new channels to send the wireless signal to the receiver unit at new channels until the transmitter unit receives the response signal. Therefore, the receiver unit can correctly receive the wireless signal and overcomes the signal missing problem induced by channel interferences. The light apparatus increases the wireless signal transmission effect. |
