IoT Enabled Phase-Cut Dimmable Power Supply for LED Fixtures

This paper describes the design and development of an Internet of Things (IoT) enabled light-emitting diode (LED) phase-cut dimmable power supply. The FL5160MX is a robust controller that enhances flexibility with a selectable DIM mode pin to facilitate trailing-edge or leading-edge dimming. This design encompasses both hardware and software subsystems. The hardware components include an Arduino UNO Rev4 Wi-Fi, current sensor, relay, Liquid Crystal Display (LCD), AC/DC Converter, and the dimmer circuit power supply. The software component controls the circuit protection and connects to the Arduino Cloud through the IoT. The proposed concept provides an effective solution supporting leading- and trailing-edge phase-cut dimming, efficient power supply, and flexible means of control.
