diplomsko delo

Abstract

Cilj diplomskega dela je ovrednotenje obstoječih meril za minimizacijo učinka svetlobnega onesnaževanja okolja v našem ekosistemu. Osredotočili smo se predvsem na Slovenske zahteve ter mednarodna priporočila CIE, ki je najširša mednarodna organizacija na področju razsvetljave. V Sloveniji velja kot glavno merilo za omejevanje priključna moč za razsvetljavo na površino, ki jo osvetljujemo in dovoljena poraba energije za razsvetljavo na prebivalca. Pretekle analize so pokazale, da obstajajo možnosti, da se omeji in celo zmanjša vpliv na okolje zaradi umetnih svetlobnih virov, ki so vzrok za svetlobno onesnaženje , hkrati pa nudijo stroškovne in energetsko varčne rešitve Zahteve in standardi se po svetu bistveno razlikujejo, zato jih je potrebno preučiti in analizirati ter jih dodelati tako, da bodo merila čimbolj objektivna in sprejemljiva tako za astronome kot tudi za ekonomiste, uporabnike in projektante razsvetljave. V drugem delu diplomske naloge je prikazan poskus izbire objektivnih kriterijev. V zaključku diplomske naloge je prikazan numerični izračun in simulacija izbranega odseka cestne razsvetljave z okoliškimi objekti v programu ReluxPro,. Rezultati simulacije prikazujejo odvisnost neželene svetlobe od izbire svetlobnega vira, tipov uporabljenih svetilk, kjer je delež svetlobnega toka, ki izhaja iz celotnega odseka bistveno nižji z uporabo svetilk z LED tehnologijo v primerjavi s predhodno uporabljenimi natrijevimi sijalkami.

Secondary title:	ANALYSIS OF CRITERIA FOR THE EVALUATION OF LIGHT POLLUTION
Secondary abstract:	The aim of the thesis is the evaluation of existing criteria to minimize the effects of light pollution in our ecosystem. We focused mainly on the Slovenian requirements and the requirements of CIE for a wider part of the world. In Slovenia, the primary measure of power is connected to the surface and allowed power consumption for lighting per capita. Also, the analysis has shown that there are options to limit or even reduce the environmental impact of artificial light pollution, while delivering cost-effective and energy-saving benefits. However, the requirements and standards around the world vary considerably, so it is necessary to examine and optimize this by using refined measurement to find a common language so astronomers as economists and technicians. Towards the end we have to show by choosing objective criteria. The thesis was then completed with a simulation of the selected portion of the program ReluxPro and found that the current share of the luminous flux on the surface is significantly lower with the use of lamps with LED technology from their previous sodium lamps.
