This invention refers to a gateway of Internet of Things which supports Bluetooth, WiFi protocol and adjustment of smart light. From top to bottom, it consists of the movably connected top cover, surface cover, and bottom shell. The top cover fastens the shading film, light guide plate and light panel to surface cover's step surface from the top down successively; the surface cover is equipped with a Bluetooth antenna and a WiFi antenna on its inner wall; there is an electric connection between main board within the bottom shell and light panel, Bluetooth antenna and WiFi antenna. Besides locating multiple devices which support BLE protocol within about 350-meter-radius range and acquiring their data, this structure uploads the data to cloud server and exercises real-time control over these devices. Meanwhile, users may log into cloud server by mobile phone to control RGB SMD lamp—adjust light color and display model in real time. Thus, it can be seen that this structure can offer various lighting combinations that can improve user experience.
