20.500.12556/DKUM-12949 IZVEDBA IN MERJENJE RAZSVETLJAVE V CESTNIH PREDORIH REALIZATION AND MEASUREMENT OF ROAD TUNNELS LIGHTING Za varno vožnjo skozi predor skrbi več sistemov. Dolžina predora ima pri projektiranju zelo pomembno vlogo, saj je prav od dolžine predora odvisno, katere posamezne sisteme nadzora in vodenja mora predor imeti vgrajene. LED-smerniki in smerne svetilke so namenjeni izboljšanju vidnega vodenja in v primeru nesreče opozarjajo na nevarnost ter označujejo smer umika. Pomembne so tudi svetilke na temenu predora, ki osvetljujejo predor. Pri izvedbi razsvetljave je treba upoštevati standarde, določila, ki podajajo minimalne zahteve za svetlost predora. V nalogi smo predstavili razsvetljavo v predoru Golo rebro z LED-smerniki, smernimi svetilkami in razsvetljavo na temenu predora in opisali njeno delovanje. Predstavili smo merilno metodo meritve svetlosti in osvetljenosti v predoru ter merilno metodo meritve impedance okvarne zanke in kratkostičnega toka. Izvedli smo meritev svetlosti cestne površine in osvetljenosti zidu med dvema svetilkama v notranjem območju predora, meritev svetlosti cestne površine uvozno-vstopnega območja predora in prehodnega območja predora ter meritev impedance okvarne zanke in kratkostičnega toka. Safe driving through tunnels is enabled by several systems. The length of the tunnel plays an important role in its design as the length is the feature that determines which control and guidance systems have to be installed in the tunnel. LED indicators and direction indicator lamps have the purpose of enhancing visual guidance and in case of accidents warn about the danger and indicate the exit route. The lights at the top of the tunnel that illuminate the tunnel are also important. When constructing the lighting, the standards and provisions that provide the minimal requirements for the luminance of the tunnel have to be observed. In this thesis we presented the lighting in the Golo rebro tunnel, which includes LED indicators, direction indicator lamps and lights at the top of the tunnel, and described its operation. We described the method for measuring the luminance and illumination in the tunnel and the method for measuring impedance of the fault loop and short-circuit current. We performed the measurements of road surface luminance and wall illumination between two lights in the inner tunnel area, measurements of road surface luminance in the entrance-exit and transitional area of the tunnel and impedance measurement of the fault loop and short-circuit current.
