Abstract
Bodoča osvetlitev na podlagi polprevodniških virov svetlobe bo spremenila nočno podobo mest. Možnosti njihove umestitve in uporabe v urbanem prostoru so številne. V disertaciji proučujemo, ali bi njihova prihodnja uporaba v splošni zunanji razsvetljavi pozitivno vplivala na človekovo sprejemanje tako osvetljenega urbanega prostora. Na podlagi inovativne uporabe LED- in OLED- svetil smo izoblikovali dva različna koncepta osvetlitve. Prvi koncept temelji na ploskovni osvetlitvi, drugi pa na detajlnem prikazu arhitekturno urbanih elementov. Predlogi osvetlitve so bili narejeni na različnih lokacijah mesta Ljubljane. Poleg izpolnjevanja funkcionalnih potreb upoštevajo tudi urbanistični in arhitekturni vidik osvetljevanja. Z ocenami afektivne kakovosti slikovnih prikazov smo predstavili in proučevali temeljna afektivna stanja anketiranih. Ugotovitve kažejo, da so se anketirani pri večini predlogov strinjali pri ocenah spremenljivk »prijetnost« in »pozornost. Statistika pokaže med konceptoma značilne razlike pri ocenah obeh spremenljivk. Pri neposredni primerjavi obeh konceptov smo ugotovili, da je naklonjenost anketirancev do določenega osvetlitvenega koncepta odvisna tudi od mestne lokacije. Ocene so pri več kot pol predlogih značilno odvisne od starosti anketiranih. K zmanjšanju porabe električne energije bi lahko pripomogel le detajlni koncept osvetlitve. Z disertacijo želimo poudariti pomen nočne podobe mest pri razvoju prihodnjih strategij osvetlitve, ki temeljijo na polprevodniških virih svetlobe.

Title:LED and OLED lighting in urban design and their influence on the urban elements of the enivornment
Abstract:
Future lighting solutions based on solid-state lighting will transform the appearance of cities at night. They can be positioned and used in an urban environment in numerous ways. Our research studies whether their future use in general outdoor lighting will positively affect people’s acceptance of urban space illuminated in this way. Two different lighting concepts were formed based on the innovative use of LED and OLED lighting. The first concept is based on plane lighting, and the second is based on a detailed depiction of architectural and urban elements. Lighting proposals were designed for different locations of Ljubljana city. They consider not only functional needs, but also urban planning and the architectural aspects of illumination. The study of the underlying core effects on the respondents through their assessment of the affective quality of graphic representations is presented. Our findings indicate that the respondents strongly agree with the assessment of the “pleasantness” and “arousal” variables of most proposals. However, the statistics show characteristic differences between the answers of both variables for both concepts. Direct comparison of the two concepts shows that the respondents’ attitudes towards a certain lighting concept also depend on their location in the city. Significant effect of the respondents' age dependency on the assesment for more then half lighting proposals is observed. Only detailed concept could contribute to lowering the electrical energy consumption. Dissertation emphasises the importance of the appearance of a city at night in developing future lighting strategies based on solid-state light sources.
