An integrated embedded controller for high power LED rope light application is designed and developed to control the power flow as well as the LED display patent for long ranges rope light applications. Nowadays, technology rope light controller being marketed is mostly low power, limited length led rope light capability and difficulty in synchronization the LED pattern for long distance application. In addition, technology LED rope light that is controlled by using power 240V AC is still new in Malaysia because most of the manufacturers and system integrator producing DC powered-based LED display system. The existing LED rope light controlled has limited control capability for controlled up to 100 meters distance. Most of the applications required 1km to 2km length of LED rope light and need at least 8 to 10 unit of controllers at on time. This will cause synchronization problem among the controllers. Due to that, the time for LED rope light taken to ON and OFF the light is not consistent and very difficult to control. The connectors between the LED rope light modules always burned because surge AC current and voltage during ON-OFF period. To ensure the controller and the rope light LED operates in the save condition, a micro-controller based high power LED embedded controller is developed to solve the critical problems for up to 4km rope light LED that can accommodate 3 to 4 building in one time. Advantages of the system are long ranges applications, cost effective and maintenance, avoid surge current and voltage and programmable. The hardware was designed based on the integrated SCR power module, snubbed protection, full-bridge rectifier and embedded micro-controller.
