Abstract:V magistrskem delu je obravnavano področje LED diod in iz njih izdelanih LED svetil, ki omogočajo racionalno porabo električne energije za razsvetljavo v primerjavi s klasičnimi žarnicami z volframovo nitko, katerih izkoristek je majhen, življenjska doba pa kratka. V teoretičnem delu magistrske naloge je tako predstavljen princip delovanja LED svetil in njihovega osnovnega elementa LED diode. Pozornost raziskave v magistrskem delu je bila usmerjena k polprevodniškim materialom in nastanku p-n spoja, ki je ključen za fotoefekt v svetilih. Predstavljene so prednosti LED diod, ki odtehtajo njihove slabosti, ki so v začetni fazi bile predvsem povezane z agresivnim občutkom dajanja svetlobe in vplivom na človeški vid. Na podlagi pridobljenih podatkov je prikazano, da se cena LED svetil že več let znižuje, hkrati pa se z ekonomijo obsega znižuje njihova prodajna cena. V nadaljevanju je predstavljen problem svetlobnega onesnaževanja, ki je vsak neposreden ali posreden vnos umetne svetlobe v okolje. Svetlobno onesnaženje je posledica prevelikega števila svetil javne razsvetljave in drugih svetlobnih virov, ki negativno vplivajo na ljudi in živali. Posebne omembe je vreden tudi ugoden finančni vidik vgradnje LED svetil v primerjavi s konvencionalnimi svetili. Ugotovitve raziskave potrjujejo, da se lahko z zamenjavo obstoječih svetil z novejšimi LED svetili zmanjša efekt svetlobnega onesnaženja, hkrati pa se racionalizirajo stroški v podjetjih, kar je prikazano v aplikativnem delu.

Title:ECONOMIC AND ENERGY EFFICIENCY OF LED LIGHTING
Abstract:The objective of this Master's study is the field of LED diode and LED lamps manufactured from them, which enable lower energy consumption for lighting compared to conventional bulbs with tungsten wire, whose efficiency is low and lifetime short. In the theorethical part the principle of the LED lamp and its basic element LED diode are presented. The attention in this Master's research is focused on semiconductors and the creation of the pn-junction which is cruical for the photo effects in lamps. The advantages of LED diodes which compensate for their disadvantages are presented as well. Especially in the beginning phase the use of LED diodes was linked to the feeling of producing agressive light and having bad influence on human sight. On the basis of the collected data it is shown that the price of LED lamps is getting lower over the last years and consequently, due to the increased sale, the selling price as well. Additionally, the problem of light pollution is presented. Light pollution is the introduction, directly or indirectly, of artificial light into the environment due to excessive number of lamps, public lighting and other sources of light that have adverse effects on human health and animals. Not to mention the favorable financial aspect of assembling LED lamps instead of conventional lamps. The research has confirmed that the replacement of the existing lamps with LED lamps can lower the effects of light pollution and rationalize the costs in firms, which is also shown in the practical part.
Keywords:LED lightings, diodes, light pollution, semiconductors, p-n junction
