Öresund Bridge and Malmö CityTunnel

  • Öresund Bridge and Malmö CityTunnel
  • Lamp efficacy

    Lamp efficacy

    Ensuring the lamp efficiently converts electricity into light (lm/W).

  • Ballast classification

    Ballast classification

    Controlling the electricity supply to the lamp (Energy Efficiency Index).

  • Luminaire distribution

    Luminaire distribution

    Controlling light emission using optics which bend and shape the light to the correct location.

  • System efficacy

    System efficacy

    Combining optical and thermal control within the luminaire (luminaire lm/W).

  • Presence/absence detection

    Presence/absence detection

    Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.

  • Daylight detection

    Daylight detection

    Artificial lighting which responds to the natural light conditions.

  • Constant illuminance

    Constant illuminance

    A function designed to produce correct light levels for the duration of the maintenance period.

  • Task-scene setting

    Task-scene setting

    Allowing the user to set scenes and adapt the lighting to different tasks.

  • Timed off

    Timed off

    Automatic cut-off can be installed to turn all lights off during unoccupied hours.

  • Task lighting

    Task lighting

    Lighting task areas with the correct amount of light.

  • Zoning of lighting

    Zoning of lighting

    Lighting is zoned according to area use.

  • Maintenance schedule

    Maintenance schedule

    Maintenance must be performed in response to product age, performance and environment.

  • Waste light

    Waste light

    Eliminating waste light which does not hit the intended target.

  • Reflectance

    Reflectance

    Taking advantage of light which is reflected from the surface within the space.

  • Visible smart metering

    Visible smart metering

    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

The Öresund Bridge spans the narrow stretch of sea between Denmark and Sweden, connecting the cities of Copenhagen and Malmö by road and rail. In autumn 2008, eight years after it opened, it was decided to replace the aged, deteriorated road lighting. The bridge's management authority chose Thorn Victor lanterns for their lighting performance and ability to better withstand the marine environment.

Just a few weeks later the first 360 lantern were supplied, complete with special optic to deliver uniform lighting across the four lane E20 highway.

As the volume of traffic has increased continuously since the bridge was built, a 4.6km rail tunnel is now under construction under Malmö, linking the Central Station with the Öresund Bridge. The twin bore, single track, Malmö CityTunnel, which must also operate under hostile conditions, was lit by 342 Thorn Gotthard luminaires. The project was completed in 2011.
