Osram Duris P 10 - Greater Luminous Flux and Thermal Benefits

A typical luminous flux of 1,100 lm from a robust, leadframe-based high-performance package and up to 50 percent lower system costs – those are the main benefits of the new Duris P 10 from Osram Opto Semiconductors. It also offers outstanding second board reliability which ensures long-term operation even in fluctuating ambient temperatures. These properties make the Duris P 10 ideal for use in professional outdoor lighting systems. It will be unveiled at Light + Building 2016, which takes place in Frankfurt from March 13 to 18.

At the heart of the new Duris are four 2 mm² UX:3 chips which are already being used in the renowned Oslon LED family. Osram has opted for leadframe technology for the package which, compared with similarly sized ceramic packages, combines improved thermal properties with excellent second board reliability. This term describes the thermal interplay between the LED package and the board. If very large ceramic packages are soldered onto aluminum boards fluctuations in temperature may cause mechanical stress at the solder connections. By contrast, leadframe packages can be optimized in terms of their thermal behavior and their second board reliability.

The Duris P 10 packages measures a compact 7.0 x 7.0 mm. This greatly simplifies luminaire design and reduces the space needed for the pc board and luminaire housing, which in turn means that less material is required. The high lumen value reduces the number of secondary optics needed. Together with quicker and easier handling of the luminaire in production, system costs can be reduced by as much as 50 percent.

With Duris P 10 customers benefit from optimized heat removal through the leadframe compared with similarly sized LEDs with ceramic packages. The copper core of the leadframe ensures optimum 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 were able to deliver these product benefits thanks to our automotive expertise”, explained Dr. Ralph Bertram, System Expert at Osram Opto Semiconductors. “In developing different headlight LEDs we gained extensive experience in package technology and high-current chips. We also made use of our experience in LED mass production to develop the new Duris P 10, an extremely powerful and cost-effective product for general lighting.”

All the materials for the new LED are extremely robust and are therefore ideal for outdoor applications or for use in corrosive atmospheres. The main areas of application for the Duris P 10 are street lighting, tunnel lighting, and high-bay and low-bay LED lighting systems in industrial buildings. The new Duris P 10 is available now – as is its new sister LED, the Duris P 8, with its smaller package dimensions and a luminous flux of 290 lm. In the course of the year the Duris P 9 will also be launched. This will have a luminous flux of 450 lm and will therefore be positioned in the middle of the series.
