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
High Pressure Sodium (HPS) lamps are widely used in horticulture to create the right environment for plants to grow in the dark season. A typical one hectare greenhouse using HPS lamps will consume around 10,000 Mega Watt Hour of electricity per year.
“Based on some researches, we found that only 7% of the light created by HPS lamps is absorbed

(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.
Osram TOPLEDs Encourage High Growth Yields in Plants
The firm’s TOPLED LEDs used for horticultural lighting excite plant growth and save up to 60% in energy costs.
In Honkajoki, Finland, millions of pieces of OSRAM Opto Semiconductor’s TOPLED LEDs are used in horticultural lighting system by Netled Oy.
They are designed and installed in a curtain structure of 10 strips that measure 25 meter in length each, replacing HPS lamps that are traditionally deployed in greenhouses. By creating the right wavelengths and intensity, these lighting installations are expected to achieve up to 60% energy savings.
