LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.
Osram and Hella join LED headlamp A Team
Osram – automotive lighting LEDs, control gear.
Fraunhofer IZM (Institute for Reliability and Microintegration) – interconnection and materials.
Infineon – automotive electronics and LED drivers.
Hella – optical system, headlamp structure, prototype build.
Daimler – vehicle tests.
“We have brought together major-league players in their respective sectors, assembling a wealth of expertise for this pioneering project around one table,” said project coordinator Stefan Grötsch, also head of LED automotive lighting applications at Osram.
The project is part of the ‘Integrated microphotonics’ initiative, running until the end of January 2016, sponsored by the German Federal Ministry of Education and Research (FMER). Osram is project co-ordinator.
Its aim is glare-free adaptive headlights, where modulating multiple LED die within a headlight allows the shape of its beam to be varied in response to data from forward-facing cameras in the vehicle.
Low-beams that adapt with vehicle speed are another aspect: at high speed the range of the light is automatically increased, while in city traffic the beam is widened to include more of the pavement and road edges.
“The aim of this project is to develop the technical framework for a new class of energy-efficient LED headlamps with supplementary traffic safety functions,” said Osram. “This can provide the basis for adaptive forward lighting systems [AFSs] that offer drivers and passengers increased safety.”Tags: co ordinator, road edges, safety functions, stefan gr, system 2c
