Osram Opto Semiconductors to unveil its automotive LED prototype with a brightness of up to 2000 lumen at ISAL 2015

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.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.

This in turn reduces system costs considerably and makes the LED solution a viable alternative for vehicles that are now equipped with HID lamps. 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. 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.
