LED Headlights for Illumination and Visualization

LED Headlights for Illumination and Visualization

In the interview, Sam from ams OSRAM highlights the evolution of their EVIYOS micro-LED technology, moving from current production models to advanced future iterations.

EVIYOS Generation 2 (Current Production)

This generation is already commercially available in vehicles like the Opel Grandland and Volkswagen models.

  • High-Resolution Emitter: A single component containing over 25,000 individually addressable pixels.
  • Camera-Driven Intelligence: The system uses an onboard camera to read the road scene (oncoming traffic, pedestrians, etc.) as a video input, allowing for dynamic, “glare-free” high beams.
  • Beyond Illumination: It supports visualization, enabling the projection of symbols, logos, or safety signage directly onto the road surface.

EVIYOS Generation 3 (Future Roadmap)

The next generation focuses on performance efficiency and architectural flexibility.

  • Increased Brightness: Provides more light output at the same power level or allows for better thermal management by reducing drive current.
  • EVIYOS Flex: A new variant that allows car makers to group the 25,000 pixels into customized clusters via software.
  • Reduced Bandwidth: By moving from a “display-style” addressing (Gen 2) to a “zoned-backlight” approach (Gen 3), the system significantly lowers the data requirements for the vehicle’s electronic architecture.

The “Warm White” Possibility

While the industry currently operates within a narrow “cool white” regulatory box, Sam confirmed that ams OSRAM has the technical capability to produce warmer color temperatures (resembling classic halogen) if there is sufficient consumer and OEM demand.


Detailed Comparison: Gen 2 vs. Gen 3

FeatureEVIYOS Generation 2 (HD 25)EVIYOS Generation 3 / Flex
Pixel CountUp to 25,600 pixels (monolithic array).Likely same count (25K), but with improved grouping.
BrightnessTypical 85 – 100 MNits.9% to 16% higher brightness (varies by variant).
Addressing ModeDisplay-style: High bandwidth; every pixel is unique.Zoned-style: Grouped pixel clusters (customizable).
Data BandwidthHigh; requires robust processing for video input.Significantly reduced; opens tech to mid-range cars.
Thermal Mgmt.Standard high-power LED cooling required.Improved; higher brightness at lower drive current.
Stray Light ControlBaseline control.Optimized; simplifies headlamp optical system design.
