Green to the smallest detail - OSRAM Opto Semiconductors’ LED complement the Tchibo concept of sustainable coffee bars
Regensburg, Germany, 2010-Dec-02
â??insgrÃ¼ne' [â??into nature'] – this is the name of Tchibo's new coffee-bar concept for universities. For the interior, designer Simon BrÃ¼nner of â??neuesLicht' contributed matching pendulum luminaires. His â??Dropled 100', using OSRAM Opto Semiconductors' OSLON SSL 80 LEDs, produces a light that is not only atmospherically pleasant but also â??green': thanks to the outstanding energy efficiency of the light diodes, lighting is particularly economical and thus ecologically friendly.
The coffee bars, to date opened at the German universities of Göttingen and Greifswald, are all-round â??green' in a number of different aspects: from their colour design and fair-trade coffee to the sustainability of their lighting. Economical and at the same time powerful LEDs play a significant part in energy-saving lighting concepts.
The qualities of LEDs by OSRAM Opto Semiconductors have convinced designer Simon BrÃ¼nner: the 80Â° reflected beam angle was most suitable for use in his pendulum luminaire. Other factors in favour of OSLON SSL LED are their efficiency (83 lm/W at 3000 K), light quality, long lifespan and compact size (3x3 mm).
A lot of light within a small space
The decisive factor for the luminaire designer's pendulum luminaires, though, was their compact size: these minute bundles of power produce a lot of light within a small space. Thanks to their small size and their low thermal resistance (typically 7 K/W), the LEDs can be placed very close to each other, thus producing a lot more light within small luminaire areas. â??Dropled 100' by â??neuesLicht' uses three OSLON per luminaire. In the pendulum luminaires fitted in the â??insgrÃ¼ne' coffee bars, the LEDs are not even visible - such is the subtlety of their use.OSLON SSL LEDs are available in a wide range of colour temperatures (2,700 – 6,500 K) and provide the right light for any mood.
â??For me, LEDs open the door to entirely new design options. Thanks to their compact size, I can approach illuminants far more creatively and realize designs that would have been hitherto unthinkable' explains Simon BrÃ¼nner, a luminaire designer with his own label and his own production of luminaires in Germany.
In the technical realization of the luminaire, Simon BrÃ¼nner was supported by the OSRAM â??LED light for you' partner Elec-Con technology GmbH located in Passau. Elec-Con is one of the new system integrators at â??LED light for you' and as such supervises the professional coordination within such projects as well as between light planners and designers. The â??LED light for you' network initiated by OSRAM cooperates with customers on the realization of new solutions using efficient and versatile light-emitting diodes.
