   The yeelight sunflower bulb is a LED lighting bulb, in which there is a wireless sending/receiving component working via Zigbee signals. The bulb receives signals from control box and changes color and brightness to what you want.

   The control box is a LAN (local area network) to the Zigbee bridge, which transforms the smartphone control commands (Wi-Fi signals) to Zigbee signals. The Control box has one LAN socket, with which it can be connected to your home Wi-Fi AP. When it boots up, an IP address will be assigned and your smartphone can search and connect to it via Wi-Fi. The following figure shows the interfaces on the control box.
