Osram brings us the latest sample of 1024 pixel LED headlamp hybrid module

05-02-2018
After a combined research project with the Fraunhofer Institute for Reliability and Microintegration, Infineon, Hella, and Daimler, Osram is showing a new sample of Eviyos automotive LED headlamp hybrid module with more than 1000 pixels and integrated driver electronics, which could be the next development in vehicle front lighting beyond shipping adaptive drive beam lights.
Osram and its partners are showing the prototype of the 1024-emitter vehicle LED headlamp hybrid module.

Osram has been a leader in adaptive drive beam headlamps. The company announced a module that combined multiple LED segments or pixels and a silicone optic to enable auto makers to use the technology in mainstream vehicles. Still, the Eviyos LED headlamp project takes beam control to another level with the ability of the electronics to independently control 1024 individual emitters or pixels as opposed to controlling three to a dozen groups of emitters that form larger pixels or segments. The key to the granularity is the combination of driver electronics and intelligence in the module.

The hybrid LED headlamp is another example of our products helping greatly to improve the quality of life in many different areas. Eviyos can help to make the roads safer and improve comfort and convenience for drivers.  The usage of the word hybrid in the above saying is key in understanding the architecture of the module. In terms of electronics and semiconductor industry , a hybrid refers to a device that integrates multiple ICs and/or different semiconductor components on a substrate and that can be handled like a large IC, although it is not a monolithic device. In the case of Eviyos, the hybrid integrates the LED array, driver electronics, and intelligent control.

The said hybrid LED headlamp module has a footprint of 4X4 mm. The current sample device can deliver 3 lm/pixel at a drive current of 11 mA. And Osram has showed the ability to up the flux output to 4.6 lm/pixel.

Osram does not plan on selling the Eviyos LED headlamp modules commercially until 2020 — although with the long development cycles in the automobile industry, technical teams will be selecting 2020 components now if not earlier. Osram said some designs might adopt multiple Eviyos modules or combine one of the modules with more traditional LED headlamp components.
