This paper analyses harmonic emission of different light-emitting diode (LED) lighting systems. Basic mathematical analysis of harmonic emission was presented. Paper deals with single LED lights (bulbs) and street lighting systems formed by luminaries. Harmonic emission results were obtained by measurement. More, single LED bulbs were modeled within EMTP-ATP software. Comparison of measured results and results obtained by simulation was performed. Further, one LED lighting system was compared with sodium lighting system in the harmonic emission area. Comparison was performed by replacing one sodium lighting system (in one street) with appropriate LED lighting system. Standards which deals with harmonic emission were presented and compared. More, obtained results of harmonic emission were compared with valid Standards. The goal of paper is to compare harmonic emission of various bulbs and on other side to analyze LED lighting systems with luminaries. It is important because today there are various LED lights in market made by various companies. It is due high share penetration of LED lighting in each area and their implementation in: house, buildings, business areas, factories, street lighting systems etc. On other side, LED lights are nonlinear loads which potentially can have negative effect on distribution grid. One more goal is to compare measured results and the results obtained by modeling. Correctly modeled LED lighting can be used in various research. It can be used to improve the manufacturing process of LED lights.
