LED installations exceed expectations

Maintenance costs cut to almost zero and energy requirements reduced by up to 85%

LEDs have promised much for architectural projects, but to date actual performance has remained largely untested.

Now, 24 months since the first Luxeon LED luminaires were designed and installed in two major European lighting projects, the luminaires are meeting and exceeding projections, outperforming traditional systems and proving more economical.

Used by Bocom (www.bocom-energy.de) as the sole light source in the bar of the Hotel Anna in Munich, Germany, Lumileds' LEDs create a key attraction through the use of dynamic colour-changing light.

In total over 1800 LEDs from Lumileds, housed in 12 luminaries throughout the bar area, are used to create the control and imagery needed for this designer hotel.

Opened in November 2002, the lighting solution has required only one service since its installation - this due to the disconnection of a cable during cleaning - reducing maintenance costs to almost zero, while using only 10 per cent of the energy required for the previous system.

Harald Spilker, sales and marketing manager of Bocom , said: "The success and on-going high performance of the Hotel Anna solution underlines the benefits of Luxeon LEDs".

" Creatively we were able to achieve far greater control and dynamism over the lighting solution, while the minimal maintenance and on-going cost savings provide the hotel with a high-performance, cost-effective installation.

Bocom is also responsible for the 35,000 Euro lighting refurbishment of the Rhein Tower, Dusseldorf's tallest building.

62 Bull-eye lamps, each containing 12 Lumileds Luxeon I light sources - four each of red, green and blue - replaced the original 100-watt incandescent lamps of the tower, which before had to be changed once every two years at a rate of 150 Euros each.

The solution went live in February 2003 and since this date has operated with no problems.

It is still connected to one of Bocom's computers, allowing Bocom technicians to operate special lighting programmes that support one-off events in the city, and is currently estimated to be saving Dusseldorf 85% in energy costs per year.

Keith Scott, market development manager at Lumileds, added: "The success and performance of Luxeon in major projects such as these underlines the advances Lumileds has made in LED technology".

" With the launch of the Luxeon Lighting Network a growing number of companies are now benefiting from advanced support in their development of LED-based solutions, and over the coming months we shall see an ever greater range of applications taking advantage of the creative design, energy-efficiency and low-maintenance benefits of Luxeon applications.
