Oslon Black Flat S for Automotive Provides up to 2000 Lumen

Osram Opto Semiconductors is unveiling an LED prototype in surface mount technology (SMT) with a brightness of up to 2000 lumen (lm) at ISAL 2015 – the Oslon Black Flat S. Experts achieved this high output by combining five chips from the latest UX:3 generation with an improved SMT package. A single LED is therefore sufficient as the light source for combined low-beam and high-beam systems. The excellent thermal connection with the package allows for passive cooling, which reduces system costs. The Oslon Black Flat S is consequently a viable alternative to HID (High Intensity Discharge) lamps and is scheduled to be added to the Osram automotive portfolio at the end of 2016.

Osram Opto Semiconductors is showcasing the new SMT prototype Oslon Black Flat S with five high-current chips at ISAL 2015 (International Symposium on Automotive Lighting). In terms of increasing output, this is a logical development of existing versions of the automotive product family and shows that high luminous flux values of up to 2000 lumen (lm) are possible from a single light emitting diode (LED). At the same time, the SMT component has a footprint of 3.75 mm x 7.9 mm, which is only slightly larger than that of the previous 5-chip version.

Improved heat distribution – essential in view of the high currents involved – provides the basis for the high brightness. This brightness comes from five high-current chips based on latest-generation UX:3 technology, together with an improved package. The thermal connection has been greatly improved by larger contact pads, which means that the headlights can benefit from passive cooling. This in turn reduces system costs considerably and makes the LED solution a viable alternative for vehicles that are now
equipped with HID lamps. At a current of 1 ampere (A), a power loss of 12 watt (W) and an ambient temperature of 25°C, the temperature at the chip is only 69°C, which means that the temperature difference compared with the predecessor version has been reduced from 58°C to 44°C. The prototype LED is operated at a current of 2 A and a voltage of 15.5 V. The optical output is 6.5 W.

“The five chips of the Oslon Black Flat S can also be driven individually”, said Stefan Grötsch, Senior Key Expert Automotive Application Engineering at Osram Opto Semiconductors. “The future LED version will therefore be ideal for adaptive front lighting systems.”

Developers at Osram Opto Semiconductors have succeeded in significantly improving the thermal management of the Oslon Black Flat S prototype (left) compared to the predecessor version (right).

About Osram:
Osram, with its headquarters in Munich, is one of the two leading lighting manufacturers in the world. With its extensive portfolio the company covers the entire value added chain from components – including lamps, control gear and optical semiconductors such as light emitting diodes (LEDs) – to luminaires, light management systems and complete lighting solutions. Osram employs around 34,000 people worldwide and achieved sales in fiscal 2014 of more than 5.1 billion euros (year ending September 30). For more than 100 years the focus of its business activities has been light and therefore quality of life. On July 8, 2013 the company was listed for the first time on the stock markets in Frankfurt am Main and Munich under SIN: LED 400 (abbreviation: OSR).
