“…As a result, a decrease in the power quality of power distribution as a large number of LED lamps are usually connected to the same bus, resulting in high current harmonic distortion fed into the power system. For this reason, the power quality resulting from using LED lamps in power distribution systems needs to be studied and analyzed [38][39][40][41][42][43][44][45]. In Molina et al's work [38], a frequency-domain low-watt LED lamp model for current harmonic distortion calculation, which is applied for large-scale harmonic penetration, is discussed.…”

Harmonics and Reduction of Energy Consumption in Lighting Systems by Using LED Lamps

This paper proposes the study and analysis of harmonics, energy consumption and power quality of light emitting diode (LED) lamps equipped in building lighting systems. LED lamps with external (LED MR16) and internal (LED light bulb) drivers are investigated using an experimental setup to compare the results. The power quality of both LED lamps is studied by using a power quality meter to measure the generated harmonic currents from various case studies. The case study is divided into four major cases: one LED lamp is turned on with one driver, two LED lamps are turned on using the two drivers, eight LED lamps are turned on with one driver, and eight LED lamps are turned on with the eight drivers. As harmonics are related to total power factor (PF), which affects the energy savings of the building, hence, a filtering circuit to reduce harmonic current has been designed and implemented to improve power quality and/or power factor of the system. The different cases of harmonic filter insertion at the input of an LED lamp’s driver are discussed and then compared with a lighting standard to show the effectiveness of the passive filtering technique used in the studied system. In addition, the obtained result can be applied to both newly built and retrofitted buildings that aim to use LED technology to increase energy efficiency and decrease energy costs, and could be a helpful guide for end-users and manufacturers in addressing and developing LED issues.

“…The use of such light sources is also economically advantageous-the long life means lower investment costs, and the low active power consumption translates into lower operational costs. Despite many advantages, the electroluminescent light sources have one major drawback-they cause strong distortions in the current [13][14][15][16][17][18][19][20][21][22][23][24].…”

“…If the number of LED lamps connected to electrical systems constitutes a significant part of all of the electrical light sources in a facility, then, because of the level of power consumed, problems with the impact of higher harmonics in such mains occur. In many scientific centres from all over the world, research related to the quality of the electricity in the power systems of LED lamps is conducted [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. At the same time, different solutions aimed at the improvement of the electricity quality parameters in these systems are proposed [33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

Disturbances Generated by Lighting Systems with LED Lamps and the Reduction in Their Impacts

2019

The paper deals with electromagnetic disturbances in the form of current higher harmonics, which are generated by LED lighting elements. It presents the problems related to the formation and impact of higher harmonics in the electrical systems of commercial facilities. The results of tests and analyses of current distortions for two different LED lamps are included, and these are in reference to the parameters set out in the normal applicable standards. A system was then proposed to improve the quality of energy in the mains of commercial facilities in the form of a two-stage power supply. Tests of the systems with the aforementioned LED lamps were conducted and commented upon after introduction of the two-stage power supply. The final part of the paper contains a summary of the obtained test results.
