Osram Opto’s LEDs Used in Tchibo Sustainable Coffee Bars
‘insgrüne’ translated as ‘into nature’ is the name of Tchibo's new coffee-bar concept for universities.
For the interior, designer Simon Brünner of ‘neuesLicht’ contributed matching pendulum luminaires. His ‘Dropled 100’, using Osram Opto Semiconductors’ OSLON SSL 80 LEDs, produces a light that is atmospherically pleasant. Furthermore, it is also economical and ecologically friendly thanks to the outstanding energy efficiency of the LEDs.

The coffee bars, to date opened at the German universities of Göttingen and Greifswald, are all-round ‘green’ in a number of different aspects: from their color 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’s have convinced Brünner that the 80° reflected beam angle was most suitable for use in his pendulum luminaire. Other factors in favor of OSLON SSL LED are their efficiency (83 lm/W at 3000 K), light quality, long lifespan and compact size (3x3 mm).
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.
‘Dropled 100’ by ‘neuesLicht’ uses three OSLON per luminaire. In the pendulum luminaires fitted in the ‘insgrüne’ 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.
‘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 Brünner, a luminaire designer with his own label and his own production of luminaires in Germany.
In the technical realization of the luminaire, Simon Brünner was supported by the Osram ‘LED light for you’ partner Elec-Con technology GmbH located in Passau. Elec-Con is one of the new system integrators at ‘LED light for you’ and as such supervises the professional coordination within such projects as well as between light planners and designers.

In two ‘insgrüne’ branches to date, energy-efficient luminaires designed by Simon Brünner and fitted with LEDs by OSRAM Opto Semiconductors complement the sustainable concept of these university coffee bars.
OSRAM is part of the Industry sector of Siemens and one of the two leading lighting manufacturers in the world. Its subsidiary, Osram Opto Semiconductors GmbH in Regensburg (Germany), offers its customers solutions based on semiconductor technology for lighting, sensor and visualization applications.
Osram Opto Semiconductors has production sites in Regensburg (Germany) and Penang (Malaysia). Its headquarters for North America is in Sunnyvale (USA), and for Asia in Hong Kong.
