The article describes the measurements of power quality parameters of load which is mapping the lighting installation of LED sources. Study were performed on a specially constructed the experimental setup which allows for the measurement of electrical parameters and distortion from electroluminescent lighting. In the paper quoted the legal basis in the field of power quality, referring to the Standards: PN EN 50160 “Voltage characteristics of electricity supplied by public electricity networks” and PN–EN 61000 “Electromagnetic compatibility (EMC)”. Also has been presented a comparative study of LED light sources from various manufacturers, working individually and in a group. Shown the waveforms of current intensity and the bar graphs of higher harmonics of current. Additionally has been plotted the characteristics of total harmonic distortion ratio of current intensity THDi in the relation to the active power cooperating LED lamps. Finally the results of research has been analyzed and summarized.

The article describes the design, construction and research capabilities the experimental setup for measure the parameters of power quality of load which is mapping the lighting installation of LED sources. The standing has been build in order to study the disruption comes from the electroluminescent lighting mostly. The construction of standing also allows conducting the experimental research with the equipment which could improve the quality of electricity. In the paper quoted the concept of the power quality according to suggestion of Advisory Committee on Electromagnetic Compatibility (ACEC). Also has been presented the causes and consequences of exceeding the permissible values of power quality parameters. In the publication has been described the procedure for preparing and setting up the experimental setup for measuring the higher harmonics of current flowing through the tested LED lighting.

W związku z rozporządzeniem Komisji Europejskiej o wymianie mało efektywnych energetycznie źródeł światła na źródła energooszczędne oraz z gwałtownym rozwojem źródeł LED, źródła te stają się jedną z głównych technologii stosowanych do oświetlenia. W sprzedaży szczególnie dużo jest rozwiązań opartych na technologii LED, które stanowią zamienniki klasycznych żarówek. W artykule przedstawiono wyniki badań podstawowych parametrów świetlnych półprzewodnikowych zamienników żarówek klasycznych. Do badań wybrano lampy LED o różnych mocach. Następnie zostały wykonane pomiary strumienia świetlnego, temperatury barwowej oraz współczynnika oddawania barw, przy różnej wartości temperatury radiatora, która wpływa na podstawowe parametry świetlne źródeł LED. Otrzymane wyniki pomiarów, zostały porównane z parametrami deklarowanymi przez producentów.

In connection with the Regulation of the European Commission about the replacement of little energy efficient light sources with energy-efficient sources and with the rapid development of the LED sources, these sources are becoming one of the main technologies used for lighting. There are sold especially many solutions based on the LED technology, which constitute the replacements of classic light bulbs. The article presents the test results of the basic light parameters of semiconductors of the classic light bulbs replacements. For studies there have been selected LED lamps of various power. Then there were taken measurements of the luminous flux, colour temperature and colour rendering index, at different values of the heat sink temperature, which affects the basic light parameters of the LED sources. The obtained measurements results have been compared with the rated parameters, declared by the manufacturers.
