Abstract
Pod LED rasvjetom smatramo rasvjetu koja koristi prednosti starih i nadolazećim materijala kako bi pretvorila električnu energiju u svjetlosnu. Svojom je iznimno velikom energetskom učinkovitošću potisnula druge umjetne izvore svjetlosti. Kombinirajući različite materijale kao podlogu u vlastitoj strukturi, stvaraju se novi oblici LED rasvjetnih tijela. Na takvom području prednjače materijali kao grafen i galij nitrid. Na trţištu su već u ponudi grafenske LED ţarulje. Osim razvoja suvremenih materijala, LED rasvjeta pronalazi svoju sve veću primjenu u namještajima. Jedna od vaţnijih karakteristika energetske učinkovitosti je ţivotni vijek. Kako bi rasvjetna tijela imala visoku učinkovitost, a time i dug ţivotni vijek, bitno je ulagati u projektiranje istosmjernih pretvarača. Neizravni pretvarač s transformatorom se često koristi u LED rasvjeti. Teorijska analiza u radu je potvrĎena simulacijama u programu Plecs i razvojem vlastitog poretvarača u diskretnoj izvedbi na podlozi industrijskih integriranih sklopova.
Abstract (english)
Under LED lighting, we consider lighting that uses the advantages of old and newly discovered materials to turn the electricity into light. With its extraordinarily high energy efficiency, other artificial sources of light were suppressed. By combining different materials as the backbone of its structure, new forms of LED lighting are created. In such a field, materials such as grafen and gallium nitride are at the forefront. The market already offers graphen bulbs with 10% more efficiency. In addition to the development of contemporary materials, LED lighting reveals a growing application in furniture. One of the most important features of energy efficiency is life expectancy. In order for the LED bulb to have high efficiency and long life, it is essential to invest in the design of DC/DC converters. Buck-boost and Flyback converters have been used frequently for LED applications. In this paper a theoretical analysis of Flyback converter was improved with simulations and measurements.
