high level of brightness and without visible LED light points

The glass facade presented another challenge. Here, there was a need to guarantee an even back-lighting with a high level of brightness and without visible LED light points. However, the short distance between wall and glass facade made challenging demands, both on the light-radiation characteristics of the LEDs and on the interplay with the external lens. Nevertheless, the led linear high bay light profiles from LI-EX were able to meet this precondition: "The LED profile sits below at the glass wall and needs to supply a homogeneous brightness across several metres, despite the stray power due to the glass area. For these conditions, the highly-efficient, compact Golden Dragon Plus LEDs are ideal", notes Marco Friedrich, chief executive of LI-EX.

Thus visitors to Munich’s Stachus reap the benefit of an efficient lighting solution, merging style with safety.The refurbishment of "Stachus Passagen" has been in progress since 2007, the project’s client is the Landesbank Baden-Württemberg. The architectural aspects of the project are run by Allmann Sattler Wappner Architekten GmbH, whose concept convinced the decision-makers during the initial architectural competition.

LI-EX is a part of "led high bay light for you", a network for lighting technology, initiated by OSRAM, which works jointly with customers on implementing new solutions based on the efficient and multi-faceted light diodes; since the launch of the Stachus project, the network has been providing specialist advice to the architects, Allmann Sattler Wappner.
