aim of this joint project as part of the FMER “Integrated microphotonics” initiative is to develop the technical framework for a new class of energy-efficient LED headlamps with supplementary traffic safety functions. This can provide the basis for adaptive forward lighting systems (AFS) that offer drivers and passengers increased safety with functions such as glare-free high-beams and low-beams that adapt to the speed of the vehicle. At high speed, the range of the light will be automatically increased. In city traffic, however, a wider distribution of the light can improve road safety by illuminating more of the sidewalk and other peripheral elements such as pedestrians and cyclists. These functions are fully electronic, so there is no need for mechanical actuators.
New technologies for LED headlamps
Osram Opto Semiconductors is bringing its expertise to this project as the project coordinator and market leader in LED lighting for the automotive sector. The semiconductor specialist has extensive know-how in chip and converter technologies, and Osram’s Specialty Lighting division will be developing new electronic control gear for controlling the LED headlamp system. The Fraunhofer Institute for Reliability and Microintegration (IZM) is contributing its expertise in interconnection technology and materials, and Infineon Technologies is offering its experience in automotive electronics and LED drivers. The automotive industry supplier and lighting specialist HELLA KGaA Hueck & Co. will develop the entire optical system for the LED module and the headlamps, and will build prototypes. Daimler, a major engineering powerhouse in the automotive sector, will carry out the vehicle tests.
Project coordinator Stefan Grötsch, responsible for LED applications in automotive lighting at Osram Opto Semiconductors, is satisfied with the progress so far: “We have brought together major players in their respective sectors,” he said, “and have assembled a wealth of expertise for this pioneering project.” Together, these experts will make safer driving applications a priority for automakers worldwide.
The platform for future developments is provided by existing multichip LEDs, such as the Osram Ostar Headlamp.
