Microcontroller-based high power LED rope light application

Abstract

The high-power rope light application is designed and developed based on embedded controller that integrated with I/O ports, flash memory and analog I/O ports. The recent technology of rope light application is mostly low power, limited length LED rope light capability and difficulty in synchronization of LED light pattern for long distance application. The project design consists of single phase uncontrolled rectifier, silicon-controlled rectifier (SCR) power module, snubber protection, embedded microcontroller and rope light LED. This project capable to control up to 2 kilometers distance of LED rope light, overcome the synchronization problem, minimize the maintenance cost, programmable and capable to prevent surge AC current and voltage. Experimental results are presented and compared to verify the effectiveness of the proposed controller for high-power rope light application.
