The challenge
Abbey Wood station in southeast London has undergone a major upgrade to become the southeastern terminus of Crossrail - London’s new east-west rail link. When it opens in autumn 2019, the new route - to be named the Elizabeth Line - is expected to carry 72,000 passengers per hour, and Abbey Wood is one of dozens of stations to have been upgraded or newly built in preparation.
The new Abbey Wood station has been nicknamed “the Stingray” for its unusual shape, with large zinc-surfaced wings extending into canopies on each side. The unique structure required an equally unique lighting solution.
The lighting solution
Thorn worked in partnership with Balfour Beatty and Anderson Green Building Services Consultants to come up with the concept design for Abbey Wood. The chosen solution uses Thorn’s Contrast, Areaflood Pro, Mica, College, Chalice, Voyager, Eyekon and Impactforce luminaires.
The IP66-rated Contrast 2 LED fittings have been used to highlight the arched wooden roof above the concourse, alongside Areaflood Pro fittings which provide indirect lighting to the granite-paved concourse area.
Contrast 2 is a compact architectural floodlight range combining high output LEDs of predefined beams that offers complete flexibility, while Areaflood Pro is an IP66-rated, general purpose LED area floodlight with superior optical performance, ensuring excellent visual comfort for station users. Areaflood Pro also requires virtually no maintenance due to its 100,000-hour rated lifetime on both drivers and LEDs. DALI controls have been used throughout.
In the office areas, illumination is provided by Thorn’s College linear fluorescent luminaires and Chalice LED downlights. College has a clear prismatic diffuser in tough polycarbonate for precision light control, vandal-proofing and high impact resistance.
Chalice downlights have been engineered to offer efficacy of >100lm/W for ultra-low energy consumption and a long lifetime of 50 000 hours. The high performance optic and light mixing chamber provide a uniform appearance, a unified glare ratio <19 and a high CRI of 80-90.
Thorn’s Mica Slim is a series of in-ground “drive over” luminaires, which have been used to provide guidance lighting for the external bench areas along with energy efficient, robust and impact-resistant Eyekon LED bulkheads. Impactforce LED luminaires, specifically designed for aggressive impact or corrosive environments, have been used in the plant room, and the high performance LED exit signs are from the Voyager Sigma range, with self or central automatic test options.
The result
Thorn’s comprehensive solution for Abbey Wood covers a wide variety of areas and solves numerous different lighting challenges, providing visual comfort, efficiency, safety and long life. At the same time, it makes light an integral part of a stunning and unique new piece of architecture.
