  • 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

    The use of LED luminaires with passive cooling ensures optimal running conditions. This maximises the system efficacy of the luminaire, giving the high output light for low input power, whilst requiring no parasitic energy to operate cooling systems.

  • Presence/absence detection

    Presence/absence detection

    Providing lighting only when it’s needed.

  • Daylight detection

    Daylight detection

    The use of daylight switching ensures that exterior lighting is only active when natural light is insufficient, preventing energy usage during daylight times.

  • Constant illuminance

    Constant illuminance

    Producing the correct lighting 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 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

    Zoning lighting in accordance to occupancy patterns or window location.

  • Maintenance schedule

    Maintenance schedule

    Tailoring maintenance schedules in accordance to product age, performance and environment.

  • Waste light

    Waste light

    The use of luminaires providing tight optical control allows a lighting design sympathetic to the natural environment, minimising spill light which in turn ensures energy is only used to light the target area, reducing energy consumption.

  • Reflectance

    Reflectance

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

  • Visible smart metering

    Visible smart metering

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

Thorn illluminates Copenhagen Zoo's biggest attraction

Founded in 1859, Copenhagen Zoo in Denmark is one of the oldest zoos in Europe. It comprises 27 acres and attracts more than a million visitors every year, making it one of Denmark's top attractions.

In February 2013, the zoo opened The Arctic Ring – a new and unique home for its polar bears, North Atlantic birds and seals. As well as offering the animals much better living conditions and space, the 3,200 sq m facility also allows visitors to get up close both above and below the water. Exceptional architecture combined with carfefully configured building design and lighting from Thorn provide an enchanting arctic experience which is unparalleled in Europe.

A journey to The Arctic Ring

Copenhagen Zoo's arctic journey begins in the polar bears' summer home. Vistors are led through a tunnel illuminated by Base LED downlights, which combine energy efficiency and longevity with true colour quality. Sounds of polar bears enrich the journey while posters offer the opportunity to learn about their life. Visitors then enter a submerged acrylic tunnel, allowing for a spectacular view of swimming polar bears.

In The Arctic Ring's impressive exhibition, penguins are ready to take over the entertainment. Visitors can also try to compete with the polar bear by holding their breath under the glow of Cruz LED – a high output recessed LED downlight with passive cooling, dimming and consistent colour performance.

In the outdoor polar bear cave, Troika floodlights provide illumination when daylight fades with excellent light control minimising obtrusive light for the surrounding environment. Finally, the neighbouring bird hill's rural environment is lit by the particularly robust and corrosion-proof fluorescent 7297D. This luminaire is suitable for harsh environments and resistant to bird droppings.

Michael Petersen, Manager of The Artic Ring exhibition says: "When visitors enter The Arctic Ring it is important that the transition from the bright daylight into the artificial light in the tunnel and exhibition is as pleasant as possible.

"In the exhibition we also value the LED lighting because of its ability to show colours correctly and long lifetime, which minimises the cost of renewing light sources."
