An Intelligent Lighting Control System (ILCS) using LabVIEW

Abstract

An Intelligent Lighting Control System (ILCS) was proposed and designed by considering ergonomic setting and energy efficiency. The integration of CompactRIO as a main hardware and National Instrument Laboratory Virtual Instrument Engineering Workbench (NI LabVIEW) 2012 as a platform to design an interactive Graphical User Interface (GUI) as well as integrating components within the system. The proportional–integral–derivative (PID) controller programmed in NI LabVIEW provides autonomous dimmer control and adjustment of the light-emitting diode (LED) lamp with respect to present Lux value. Performance tests conducted shows the developed system capable of controlling the luminosity of the LED lamp based on the luminance set point. Moreover, the result also showed the average power saving of up to 33% compared to normal use. However, several modifications and improvements are desired before the system could be applied in actual environment.
