148 TECHNOLOGY / LED CASE STUDY BLENDING STYLES
A shopping centre in Aberdeen has become one of the first in the UK to adopt an all LED lighting solution.
With over 70,000 square metres of floor space the ‘Bon Accord and St Nicholas Shopping Centre’ in Aberdeen is a popular destination for shoppers. Recently refurbished, the centre is now one of the first malls in the UK to feature an LED-only lighting solution. The lighting concept was developed by Zumtobel, who were asked to produce a unique, cost efficient, LED luminaire look that blends perfectly into the existing architecture. Colin Kennedy, Project Surveying Manager with the client Land Securities acting for owners Scottish Retail Property Limited Partnership explains: “We wanted to explore how the use of LED technology could improve the lighting levels, while also complementing the new finishes in the centre. We are extremely pleased with the result. We have lowered maintenance costs, and we also have a balance between daylight and artificial light to give optimum energy consumption.” Discussions between architects, electrical designers and Zumtobel ensured optimum integration into the existing design and made sure that

New York’s Central Park is being seen in a new LED light after the completion of a project spearheaded by CREE.
New York authorities have recently completed the installation of nearly 2,000 LED lamps in Central Park in the hope of reducing energy costs while improving the atmosphere of the world famous park for local citizens and tourists.
Lighting walkways and grassy areas, the lamps have been provided by Spring City Electrical and feature the Cree XLamp XP-G LED in each fixture, which have been produced using an advanced light engine from Heatron. The New York Department of Transportation have estimated that the new LEDs will reduce energy usage by 62 per cent and deliver savings of over $30,000 on annual maintenance costs. “Central Park presented a unique lighting challenge,” says James Brodrick, Lighting Program Manager at the US Department of Energy, the governmental branch the project was undertaken in conjunction with.
“For walkways in general, it’s important to measure both horizontal and vertical illuminance for light distribution purposes.” The luminaires have been placed on existing 9ft tall cast iron posts which are placed 80ft apart along the parks paved footpaths.

the LED technology inside the luminaires delivered the best possible lighting comfort. LED luminaires from the Careena product range were adapted to fit the 481mm round cut-outs in the shopping centre’s ceiling. Zumtobel developed another custom solution by adapting Resclite LED spots. Usually these devices are used to guide visitors safely away from danger in the event of an emergency. In Aberdeen these small LED power packages are also used to provide highlighting in everyday use. Specially tailored to fit a ceiling panel size of 31mm, the spots brighten the shopping centre’s roof with lighting accents, creating the impression of a starry sky. Light lines and downlights were also used to provide varied ambient lighting, making it easier for people to find their way around.
