LED lighting from TRILUX ensures reliable, glare-free illumination of the heavy equipment and simultaneously "simplifies" energy consumption by 63% compared to conventional systems. Plans drawn up in 2011 initially intended installing a conventional lighting system.

"LED technology didn't seem mature enough for us at the time, but achieved significant progress in the following years," explained André Aeschbacher, Head of Projects at SBB. As part of a continuous process of improvement, a decision was made during the construction phase to install an LED lighting solution.

The lighting solution tendered by TRILUX with robust, narrow-wide distribution Mirona LED planar spots prevailed. The dimmable luminaires were coupled up to daylight control, enabling daylight from the skylights to be optimally utilised. For this purpose, special sensors register the ingress and level of natural light and add only that component needed to achieve the desired lighting level. Using a light management

system further increases the energy efficiency of the lighting solution by around 30%. With the LED upgrade project, SBB saves a total of 63% in energy costs compared to standard lighting.

"We were able to offer SBB an LED solution that, compared to the competition, generated the same illumination values with less luminaires, and the somewhat higher luminaire price was balanced by the significantly lower energy consumption – the Mirona LED needs 40% less energy than the corresponding LED model of the competitor," emphasised Markus Elmer, TRILUX Managing Director, Switzerland. This rapidly pays off – the system is amortised within five years and saves over five tons of carbon dioxide yearly.

In addition to high efficiency, the Mirona LED features simple installation, easy maintenance and a lifespan of around 100,000 operating hours. "Effort for maintenance will sink drastically," said a convinced André Aeschbacher, SBB Head of Projects. Upgrading to LED therefore also pays in this regard as well.
