A Fault-Detecting and Motion-Sensing Wireless Light Controller for LED Lighting System

In this work, a light controller for an LED lighting system is proposed. The unique feature of the proposed controller is that it can detect and indicate occurrence of fault in the LED driver and the LED module separately. It also provides wireless control of the light output based on ambient light level and motion sensing. A hardware prototype of the proposed controller is developed and tested in the laboratory. From the obtained results, it is observed that the developed controller successfully detected and indicated the occurrence of fault in LED driver and LED module separately. The developed prototype varied the light output of a commercially available 10W LED module satisfactorily from 100% to 20% without flickering.
