Osram expands its application support by providing Thermal models

Osram Opto Semiconductors has announced its first thermal models for computing different LED designs available online. OSRAM has demonstrated it is high level of customer support. In addition to electrical, mechanical and optical data, a compact model for Flotherm software is now permanently available at www.Osram-os.com/thermal-files for calculating thermal behavior.

Customers can find all the documents and the latest data needed for calculating thermal variables for different designs without building costly prototypes or carrying out time-consuming measurements. “This significantly shortens the design phases and drastically reduces development costs,” said Joachim Reill, Director LED Applications Engineering at Osram Opto Semiconductors. The data is available for standard high-power LEDs in the visible range, particularly for the DRAGON family, for the Advanced Power TOPLED range, the Power TOPLED range and some OSTAR versions.

The compact model available on the website is a simplified thermal geometry model that can be integrated in “Flotherm” software and used for customer-specific calculations. It is suitable, for example, in calculating the temperature distribution in a planned system. With extended application support, it is possible to design all end-applications, including display backlighting, in terms of thermal criteria. “Our customers can use simulations to see which LEDs are suitable for which boards and then check the thermal behavior of the overall design,” said Reill.
