ams OSRAM launches new version of EVIYOS multi-pixel LED
At the Société des Ingénieurs de l'Automobile’s SIA Vision 2024 international congress in Paris, France (16–17 October), ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has launched EVIYOS HD 25 gen2 as the latest generation of its EVIYOS LED technology.
The first generation of the EVIYOS multi-pixel LED for adaptive driving beam (ADB) and projection headlamps was launched in 2023 It was first implemented by Volkswagen in its Touareg and Tiguan models equipped with headlamps made by Marelli, each of which featuring 19,200 pixels (whereas the EVIYOS light source itself can provide up to 25,600 individually controllable pixels).
Intelligent EVIYOS-based headlamps improve night driving by lighting up much more of the road ahead without dazzling drivers of oncoming vehicles. The EVIYOS LED can also be used to project symbols and pictures on the road, opening up new potential for car-to-environment communication (mainly for safety warnings and other messages). ADB headlamps also bring new features to Advanced Driver Assistance Systems (ADAS), and enable car makers to create distinctive new design and styling effects in the front of the car.
The EVIYOS HD 25 gen2 has now introduced improvements made in response to market requirements. These include:
- Enhanced brightness specification – the original EVIYOS HD 25 gen1 produces a typical brightness of 85mNits, whereas the new EVIYOS HD 25 gen2 has been improved this to a minimum brightness of 85mNits.
- Reduced stray light emission, making the headlamp’s optical system easier to design and manufacture.
- A more resilient supply chain – using ams OSRAM’s in-house capabilities ensures the continuous supply and quality of the companion ASIC that controls the LED component.
Development roadmap
ams OSRAM says that the rapid development of the enhanced product features in EVIYOS HD 25 gen2, hardly a year after the launch of the first product in the EVIYOS product family, reflects its commitment to the roadmap that it has shared with the automotive industry. The launch of EVIYOS HD 25 gen2 accordingly be followed by further product announcements and introductions in the coming years, including a version of the EVIYOS LED for low-end and mid-range vehicles.
ams OSRAM will also be announcing new customer design wins. While Volkswagen was the first to take advantage of the high-resolution projection capability of the EVIYOS LED, other car makers are following, benefiting from the customer appeal of a headlamp that improves night-time vision and road safety while providing greater freedom to shape the appearance of the vehicle and enable the creation of unique design signatures such as welcome home/leave home ‘light carpets’ and distinctive front styling.
The innovations introduced in EVIYOS LED technology have also been recognized by the federal government of Germany, which in September nominated ams OSRAM for the German Future Award – Federal President's Award for Technology and Innovation. Following a multi-stage assessment process, the EVIYOS engineering team was named as one of three finalists. The ams OSRAM engineers named in the award citation are Dr Norwin von Malm (senior director New Technologies) and Stefan Groetsch (who leads the System Solution Engineering team), alongside Dr Hermann Oppermann of the Fraunhofer Institute for Reliability and Microintegration IZM in Berlin.
