The redevelopment of London Bridge Station was part of the government’s £7bn Thameslink programme involving a major track upgrade, a new rail underpass with platforms being widened and extended to handle a 30% increase in trains.
Designplan worked closely with the contractor, NG Bailey, and the consultant, WSP, to minimise the artificial lighting in the station. We re-engineered our Flair luminaire to reduce the number of lighting points, whilst maintaining the necessary lighting levels and uniformity. This was achieved by using a low iron glass diffuser which improved light transmission. The laminated toughened glass had a special interlayer to reduce glare without affecting its efficacy.
We installed 1500 Flairs across all the platforms. The efficiency of this modified fitting meant that the distance between each luminaire was extended from 3 to 4.5 metres which reduced the required number of light fittings – saving both cost and energy.
All our luminaires were supplied with DALI drivers so that the light levels can be easily adjusted. The driver current can be increased over time to offset the lumen depreciation of the LEDs. This achieves an energy saving over the duration of the project, whilst extending the life of the product. With an IP65 rating, the Flair is a weather resistant luminaire.
There were many unique requirements for this installation as the Flair luminaires were delivered off-site and fitted to the roof cassettes where they were being manufactured. These cassettes were then transported to site and installed by crane.
With the concourse area larger than the football pitch at Wembley, a luminaire was required which produced a good output but was small enough to be in keeping with the architectural ceiling design. The Terminus was the ideal choice with over 1000 installed.
The outcome of this £1.2 million lighting project is a 19th century station illuminated with contemporary 21st century design and technology.
