The WiFi LED controller is actually an APP installed on your mobile devices, which enables users to adjust brightness, RGB color tone and color temperature smoothly. Then how can it control the lights? The answer is WiFi, and the APP shall be added to the home network via a bridge connected to the router. The bridge also has the function of a signal converter. The whole system shall include a mobile device with the APP installed, a bridge with signal converter function with RJ45 port, a router, a receiver that receives the signal and control the LED lamps. The bridge shall be connected to the router via RJ45 cable, and then the APP shall be added to home network through the bridge. The bridge will receive the WiFi signal from the mobile and converts it to RF (radio frequency) signal and sends it to the receiver, the receiver receives the RF signal and delivers PWM signal to control the connected lights. The RF receiver shall be chosen according to the input type of your LED lamps since the output ends of the receiver will be connected to the input ends of the lamps. Of course your LEDs shall be dimmable first, you can consult the salesman when you purchasing LED lights. If the they are designed with AC input, you should choose a receiver with AC output . If they are designed with DC input, a receiver with DC output should be chosen, and a AC-DC power supply maybe required for the receiver. In addition, you should figure out whether the LEDs are designed with constant current or constant voltage input. The most amazing features of WiFi LED Controller are wireless and full touch smooth control. The control distance can be single axis servo Traverse robot over 20 meters, which means you can operate anywhere in your house. Dimming, color temperature adjustment, RGB color tone adjustment, dynamic changing patterns and more can be controlled smoothly by your fingers. It is really intelligent lighting control solution.
