Osram's new Duris P 10 LED provides 1100lm and thermal benefits, cutting system cost by up to 50%

At the Light + Building 2016 trade fair in Frankfurt, Germany (13-18 March), Osram Opto Semiconductors GmbH of Regensburg, Germany is unveiling its Duris P 10 LED, suitable for use in professional outdoor lighting systems. Offering typical luminous flux of 1100 lumen (at a color temperature of 5000K) from a robust, lead-frame-based, high-performance package, the Duris P 10 can enable up to 50% lower system costs, it is reckoned, while also delivering second board reliability, ensuring long-term operation even in fluctuating ambient temperatures.

The Duris P 10 contains four 2mm2 UX:3 chips, which are also used in the Oslon family of LEDs. Compared with similarly sized ceramic packages, the lead-frame technology combines improved thermal properties with what is claimed to be excellent second board reliability. Whereas fluctuations in temperature may cause mechanical stress at the solder connections, lead-frame packages can be optimized in terms of their thermal behavior and their second board reliability.

Measuring a compact 7mm x 7mm, the Duris P 10 package simplifies luminaire design and reduces the space needed for the printed-circuit board and luminaire housing, requiring less material overall. The high lumen value reduces the number of secondary optics needed. By streamlining the handling of the luminaire in production, system costs can be reduced by as much as 50%, it is claimed. With Duris P 10, users benefit from optimized heat removal through the lead frame compared with similarly sized LEDs with ceramic packages. The copper core of the lead frame ensures optimal heat removal and more efficient operation of the luminaire in the chosen application if the same cooling system is used, or savings in the cooling system for the same luminaire efficiency. 

"We are able to deliver these product benefits thanks to our automotive expertise," says Osram Opto system expert Dr Ralph Bertram. "In developing different LEDs for headlights, we gained extensive experience in package technology and high-current chips. With our experience in LED mass production, we developed the new Duris P 10, an extremely powerful and cost-effective product for general lighting."

All of the materials used in the new LED are extremely robust, says Osram Opto, and are suitable for outdoor applications or use in corrosive atmospheres. The main applications are street lighting, tunnel lighting and high-bay and low-bay LED lighting systems in industrial buildings.

The Duris P 10 is available now along with its new sister LED, the Duris P 8, which has smaller package dimensions and a luminous flux of 290lm. Within a year, the Duris P 9 (with a luminous flux of 450lm) will also be launched.
