These efficient and innovative light sources require adequate ballast or electronic control gear, also known as LED drivers, for their operation. An LED driver provides appropriate voltage level and current for the operation of LEDs. It converts and rectifies higher voltages of alternating current to lower voltages of direct current and regulates the current flowing through LEDs at a nominal level. There are many advantages and disadvantages to using LEDs, primarily caused by LED circuits and LED drivers. The dimming influence of outdoor LED lighting on the LED driver performance is analysed in this paper, specifically the testing of an LED lighting driver by changing the load level. Results of LED driver efficiency calculated from measured input and output power, output voltage ripple measurements, and total harmonic distortion analysis are shown. Based on the measurement results, significant recommendations and concluding remarks are given"},{"@xml:lang":"sl","#text":"Z razvojem novih tehnologij je LED tehnologija (light-emitting diodes, svetleče diode) zavzela pomemben delež v razsvetljavi, predvsem zaradi dolge življenjske dobe in visoko učinkovite svetilnosti, kar omogoča prihranke pri stroških za energijo in vzdrževanje. Tako učinkoviti in inovativni viri svetlobe za svoje delovanje zahtevajo ustrezen balast ali sklope za elektronsko krmiljenje oziroma LED krmilnike. LED krmilnik omogoča ustrezno napetost in tok za delovanje LED-a, tako da pretvarja in gladi izmenični tok z visoko napetostjo v enosmerni tok z nizko napetostjo in vzdržuje nominalno raven toka skozi LED žarnico. Obstaja veliko razlogov za ali proti uporabi LED žarnico, kar je odvisno od LED vezij in LED krmilnikov. V članku je analiziran vpliv uporabe zatemnitve zunanje LED razsvetljave na učinkovitost LED krmilnikov. Članek predvsem opisuje preizkušanje krmilnika LED razsvetljave s spreminjanjem bremena in prikazuje rezultate učinkovitosti LED krmilnika, ki so izračunani na podlagi meritev vhodne in izhodne moči, meritev utripanja in celovite analize harmoničnega popačenja. Na podlagi rezultatov meritev so podane zaključne opombe in pomembna priporočila"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-HOJ6P2QX","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-HOJ6P2QX"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-HOJ6P2QX/3127ee9a-5f3e-4ddc-a93e-b08cba75d771/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za energetiko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-HOJ6P2QX/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-HOJ6P2QX"}}}}
