In high-beam mode, EVIYOS® 2.0 automatically reduces glare and offers high-resolution, fully adaptive driving beam capabilities.
To inform the driver and anyone around, EVIYOS® 2.0 projects pictures and safety alerts onto the road surface.
The first LED to have a monolithic chip with 25,600 individually programmable LEDs is EVIYOS® 2.0.
After ten years of rigorous research, EVIYOS® 2.0 was released this month for mass production.
The new h-Digi® microLED from Marelli is built on top of the EVIYOS® 2.0.
Premstaetten, Austria and Munich, Germany (July 19, 2023) -- ams OSRAM (SIX: AMS), a world leader in optical solutions, unveils EVIYOS® 2.0, a new intelligent multipixel LED type that allows for fully adaptive, dynamic headlight operation and image projection, marking a revolutionary advancement in automotive forward lighting.
In high-beam mode, EVIYOS® 2.0 may selectively light the road ahead to optimize the driver's perspective without producing the glare that other drivers usually encounter. In addition to projecting high-resolution graphics onto the road surface, the chip's 25,600 individually programmable LEDs with a 40 µm pixel pitch may be used to assist drivers around obstructions or provide warning messages to other road users.
By giving drivers more time to respond to risks that would be undetectable or partly concealed with traditional headlights, EVIYOS® 2.0 significantly increases road safety. The improved road vision also promises to change how drivers see the road at night, making it safer and simpler to drive at night.
Numerous car safety measures have been developed up to this point with the goal of protecting the driver and any passengers. It goes one step further with EVIYOS® 2.0. The car's capacity to display visuals onto the road at night allows it to interact with its surroundings and the driver in novel ways. To assist increase awareness of danger and lower the chance of accidents, headlights based on EVIYOS® 2.0, for instance, may reflect a snowflake symbol into the road surface to warn of ice or slippery conditions.
After ten years of constant technical development at Ams OSRAM, the ground-breaking EVIYOS® 2.0 is currently being produced in large quantities.
"High-resolution adaptive forward lighting is poised to become the next big differentiator for vehicles from the world's premium brands," said Wolfgang Lex, Senior Vice President Automotive at ams OSRAM. The most precisely regulated forward lighting systems are made possible by EVIYOS® 2.0, which also significantly increases value for the automobile sector.
A monolithic structure generates uniform light output.
Multiple ams OSRAM advancements in chip design and manufacturing are included into the EVIYOS® 2.0 architecture. Because of the monolithic µ-LED chip array used to create the 25,600 pixels, ams OSRAM is able to achieve very high color and brightness uniformity.
Each of the 25,600 LEDs in the EVIYOS® 2.0 product is controlled separately by a driver and a multipixel emitter. The multipixel headlamp is installed in a lensed headlight assembly and paired with an intelligent camera in adaptive driving beam systems to scan the area in front of the car. This maximizes the driver's vision of the road while allowing the headlamp in high-beam mode to dynamically turn down enough LEDs to prevent glare for other drivers. The headlamp can also precisely project along bends thanks to dynamic management of individual LEDs, increasing the driver's field of vision.
EVIYOS® 2.0 is a high-output, high-efficiency automotive light source that makes it possible for cars to save energy since just the LEDs that are necessary to safely optimize the driver's vision are turned on, preventing light waste.
The LED chip comes in a 1:4 (25,600 pixel) or 1:3 (19,200 pixel) aspect ratio and has a small 40 mm2 footprint to make it easy to integrate into stylish headlamp assemblies.
The microLED module's first design implementation with Marelli makes use of EVIYOS® 2.0.
Numerous major automakers and Tier One suppliers are using EVIYOS® 2.0 into new product ideas on a worldwide scale. For example, Marelli has revealed the h-Digi® microLED, its first multipixel LED headlamp module built on EVIYOS® 2.0.
"Ams OSRAM and Marelli are working together to change the future of automotive front lighting," said Didier Thalgott, Senior VP of Marelli's car illumination & Sensing Division. We can create solutions for international automakers that provide drivers more safety and comfort at night thanks to the h-Digi® microLED platform module, which is based on the ams OSRAM EVIYOS® 2.0. Additionally, the system makes it possible to apply the technology to mid-level automotive sectors due to its affordability, enhanced power usage, and compact design. Marelli is spearheading the next wave of digital car illumination with its h-Digi® microLED.
One of the top suppliers of automobile components
According to TrendForce's LED Industry Quarterly Report 2/2023, Ams OSRAM leads the automotive and mobility markets worldwide and holds the top spot in the automotive lighting industry. Nearly every significant section of a car uses the company's optical components and cutting-edge technology, including the external lighting with the best LED headlights, the rear lighting, the interior lighting, and decorative lighting.
Offering both edge-emitting laser (EEL) and vertical-cavity surface-emitting laser (VCSEL) technologies, the business is a pioneer in LiDAR technology. Driver and passenger monitoring is made possible by in-cabin sensing technology, and stray-field immune position sensors and battery monitoring sensors are examples of very accurate sensing technology for electric cars. Ams OSRAM is also the industry leader in replacement and aftermarket lighting for automobiles.
