Light pollution in Savinjska ravan

Popolna tema je neprijetna, zato si je človek od nekdaj želel ustvariti umetno svetlobo. Iznajdba žarnice sega šele v začetek dvajsetega stoletja, in od takrat naprej pa do danes smo presegli meje njene koristne uporabe. Svetloba se potrebuje in brez vsakršnega osvetljevanja bi bilo funkcioniranje družbe nemogoče. Vendar pa je zelo pomembno, da se z osvetljevanjem ne pretirava in da se osvetljuje Samo tam in takrat, kjer je to zares potrebno. Svetlobno onesnaževanje je velik okoljski problem. Neprimerna in pretirana osvetljenost povzroča težave Človeku, favni in flori. Z zamenjavo obstoječe nepravilne razsvetljave v Sloveniji z boljšo, ekološko razsvetljavo, bi osvetljevali navzdol, kjer se svetloba potrebuje in ne navzgor, kjer škoduje okolju. S tem bi se zmanjšal učinek tople grede, hkrati pa bi se prihranilo deset milijonov evrov letno. Proučevanje svetlobne onesnaženosti Savinjske ravni je podprto z obsežnim terenskim delom, ki je zajemalo meritve s Sky Quality Metrom, fotografiranje »All Sky« posnetkov ter glavnih virov svetlobnega onesnaževanja. Glavni viri svetlobnega onesnaževanja so neprimerna cestna in ulična razsvetljava, pretirano in napačno razsvetljene poslovne in upravne stavbe, stavbe splošnega družbenega pomena in druge stanovanjske in nestanovanjske stavbe.Complete darkness is unpleasant, therefore a human being wanted to create artificial light since long ago. Invention of a bulb goes back to the beginning of the 20th century and since then we have exceeded the limits of its useful use. Light is needed and society would not be able to function without any lighting. However, it is very important that we do not exaggerate with lighting and that we lighten only then and there, where it is really necessary. Light pollution is a big environmental problem. Inappropriate and excessive lighting causes problems to people, fauna and flora. By replacing the existing incorrect lighting in Slovenia with better, ecological lighting, we would lighten downwards, where light is needed and not upwards, where it harms the environment. By doing this, the greenhouse effect would be reduced and at the same time we would save ten million euros per year. Studying light pollution of the Savinja level is supported with extensive field work, which included measuring with Sky Quality Metro, taking photos of »All Sky« images and main sources of light pollution. The main source of light pollution is inappropriate road and street lighting, excessive and incorrect lighting of business and administration buildings, buildings of common social significance and other residential and nonresidential buildings
