When the mobile communication device (ie, the second device 24) receives the visible light signal Tx_SIG_1 (ie, Rx_SIG_2) from the Internet of Things lighting device (ie, the first device 22), the second of the mobile communication device (ie, the second device 24) is utilized. The visible light receiving module 246 senses visible light changes, receives the visible light signal Tx_SIG_1 (ie, Rx_SIG_2) and generates a light sensing result. Then, the second message processing module 242 converts the light sensing result into the received data to complete the visible light message transmission. In this way, the user does not need to use a complicated application to perform wireless device connection setting and data transmission, and only needs to use the Internet of Things lighting device (ie, the first device 22) and the mobile communication device (ie, the second device 24). The visible light communication can be completed. It should be noted that the visible light signal transmission of the first visible light transmitting module 224 and the second visible light transmitting module 244 can be transmitted by infrared rays, and the light wave is adjusted to 10 - 100 kilohertz (kHz) and controlled by infrared remote control (Infrared Remote Control) or custom encoding format to avoid interference.
