ENERGY QUALITY ANALYSIS AND IMPROVEMENT FOR FLUORESCENT AND LED LIGHT SOURCES

Abstract

Fluorescent lamps and the brand new lighting trend LED lamps are the most common used light sources both in homes and offices, and they are especially preferred worldwide due to their low energy consumption. However, both sources fall short of the quality of significant features such as power factor, harmonic components and colour rendering. Therefore, the purpose of this study is to analyse and improve the energy quality parameters for different light sources used with lighting control, especially dimming control. For this purpose, the energy quality parameters of harmonic current values, total harmonic distortion and power factor are measured and analysed for highly efficient and most preferred lighting sources such as LED and fluorescent lamps. The measurements are made in lighting control under different scenarios and dimming Suggestions are made on how to evade the disruptive effects both on the electricity network and local lighting control systems.
