Analysis and evaluation of LED lighting in the subway of Stockholm (English)
Abstract [sv]

Trafikförvaltningen, som ansvarar för kollektivtrafiken i Stockholm, har startat ett projekt för att byta ut befintliga armaturer i Stockholms tunnelbana mot LED-armaturer. Denna rapport utför förarbetet inför en kommande upphandling.

Detta arbete utvärderar olika LED-armaturers tekniska specifikationer som är lämpliga för Stockholms tunnelbana där armaturerna ska bytas ut. För denna miljö saknas det i dagsläget standarder som är anpassade för LED-armaturer. Med hjälp av litteraturstudier och mätningar kunde underlag för en kravspecifikation skapas. Mätningar har gjorts på ett urval av LED-armaturer och deras tekniska specifikation har presenterats. Samtliga armaturer klarade EMC-testerna (elektromagnetisk kompabilitet) där inga störningar uppstod vid frekvenserna för Storstockholms Lokaltrafiks (SL) radiokommunikationssystem.

Arbetet har även hanterat miljö- samt den ekonomiska aspekten av implementeringen av LED-belysning.

Abstract [en]

Trafikförvaltningen, responsible for public transport in Stockholm, has started a project to replace existing luminaires in the subway of Stockholm to LED lights. This thesis could be a basis for an upcoming procurement.

In this report, various models of LED lights technical specifications will be evaluated based on the environmental requirements in Stockholm’s subway, where the existing luminaires will be replaced. For this environment, there is no standard regarding LED lights today. With the help of literature studies and tests, a groundwork for a specification could be made. The tests were only made on a selection of LED lights and their technical specifications were presented. All luminaires passed the EMC (electromagnetic compatibility) tests that were made in order to determine any interference with Stockholm’s public transport (SL) radio communication system.

Environmental aspects and economical aspects of the implementation of LED lights has been taken into consideration.
