Abstract
Lighting system plays an important role in every life to increase quality of life and working efficiency. As population increase, urban area has been grown rapidly resulted in increased energy consumption in every section including lighting system. With the current attention in energy and environment issue, many governments have set policy to increase energy efficiency. In lighting system, conventional luminaire with low energy efficiency has been replaced with newer technology with low energy consumption and high energy efficiency such as light emitting diode (LED). Today, LED luminaire has taken considerable proportion of market share; however, the main concern regarding changing conventional lamp toward LED is power quality. This paper aims to study power quality issue in term of generated harmonics from lighting system consisting of LED lamps. The result indicates that LED lamps generate significant amount of current harmonic and cause a distortion in waveform. Thus, it needs taking power quality issue into account before replacing or installing LED into lighting system.
