Abstract

Probleemiks oli tunneli madal valgustase, kõrged energiakulud ja valgustuse mittevastavus praegustele kehtivatele standarditele. Uue valgustuslahenduse projekteerimise käigus muudeti valgusallika tüüpi, kuid tunneli ehituse tõttu tuli kasutada olemasolevate valgustite asukohti. Energiakulukad luminofoorvalgustid ning hõõglambid projekteeriti energiasäästlikema LED lampide vastu. Üks valgustuslahendus on teostatud kasutades põhivalgustina Glamox i40 valgusteid. Tegemist on odavama valgustuslahendiga ning veel suuremat kokkuhoidu saaks rakendada, kui vahetada välja ainult torud ja starterid. Nii ei paraneks tunneli üldpilt, sest hajutid on aja jooksul tuhmunud, määrdunud ning muutunud rabedaks. Teine valguslahendus on koostatud kasutades põhivalgustina Philips Flow LED valgusteid. Tegemist on kallima valgustuslahendusega, kuid antud valgustid on esteetilisema välimusega ning valgustavad tunneli käiguteid paremini. Kuna trepivalgustus ei tööta, siis projekteeriti uus trepivalgustus. Lahenduse projekteerimisel kasutati valgustitootjat kelle toodangut on kasutatud ka teistes Tallinna jalakäijate tunnelis. Arvestati ka, et valgusti peaks vastu soolasegusele lumele ja veele. Kujundvalgustuse loomisel tuleks arvestada olemasoleva põhivalguse valgustaset, sest valgustite osalisel väljalülitamisel hakkab kodanikelt kaebuseid laekuma ning hämaras valguses on vigastuse tekkimise potentsiaal suurem. Lõputöö käigus ei koostatud uut kujundvalgustust, sest selleks puudub otsene vajadus. Eesti jahedat kliimat arvesse võttes on enamuse ajast tunnelis pigem jahedam keskkond, mille tõttu kasutati evakuatsiooniteede valgustuse projekteerimisel superkondensaatoritega valgusteid. Võimalus on kasutada akudega valgusteid, kus on küttekaabel sees, mis hakkab alates +5 ℃ akut soojendama. Lisaks vajavad vahetust ka suunaviidad, sest piktogramme on aja jooksul korduvalt üle kleebitud. Majandusliku kalkulatsiooni arvestades oleks kõige mõistlikum kasutada esimest valgustuslahendust, sest tasuvusperiood on seitse aastat.

Abstract [en]

The problems were the low level of light in the tunnel, the high-energy costs and the non-compliance of the lighting with current standards. The location of the existing luminaires was used when designing new lighting solution, due to the construction of the tunnel. Low efficient fluorescent luminaires and incandescent lamps were switched for energy efficient LED lamps. One lighting solution was done using Glamox i40 luminaire as the main luminaire. It is a cheaper solution and even larger saving could be implemented by replacing only tubes and starters. Doing so the overall image of the tunnel would not improve, because diffusers have faded, become dirty and brittle over time. Other lighting solution was done using Philips Flow LED luminaire as the main luminaire. It is a more expensive solution, but these luminaires are more aesthetically pleasing and illuminate the tunnel passages better. As the stair lighting does not work, new light solution for stairs was designed. Product used in that solution is used in another underpass. It was also considered that the luminaire should withstand salty snow and water. Design lighting should take into account the light level of the existing main light, as partial switching off the lights will result in complaints from citizens and a higher potential for injury. No new design lighting was created during the dissertation, as there is no direct need for it. Considering the cool climate of Estonia, most of the time the tunnel has a rather cooler environment, due to which luminaires with supercapacitors were used in the design of the lighting of the escape routes. It is possible to use battery-operated luminaires with a heating cable inside, which starts to heat the battery from +5 ℃. In addition, emergency exit lights also need to be replaced, as the pictograms have been pasted over time. From an economic point of view, it would be most sensible to use the first lighting solution, as the payback period is seven years.
