Marelli has developed a Light Domain Controller
to enable software-defined vehicle architectures

Marelli has developed in China an innovative automotive lighting domain control unit platform,
that is able to control vehicles' front lights, rear lights, and all new 360° lighting features. In the future,even more lighting algorithms could be further integrated into this light domain controller. This
cutting-edge technology for lighting systems aimed at next-generation vehicles will be showcased at
the upcoming Beijing International Automotive Exhibition, from April 25 to May 4, alongside other
Marelli advanced technologies.
Whether it's internal combustion engine vehicles or electric vehicles, the automotive lighting control
system remains key for enhancing vehicle safety and improving the driving experience.
To meet the evolution of new electronic and electrical architectures, Marelli is advancing vehicle
lighting control system architecture with a forward-looking approach. The successful mass
production of Marelli's light domain controller has been introduced and proved in China's electricvehicles market. On the end node side, Marelli has introduced the “MCU LESS” intelligent driverconcept, greatly enabling the opportunity to centralize the whole lighting software into domain ECUs,
perfectly supporting the automotive industry's trend toward software-defined vehicle (SDV).
As lighting functions become increasingly independent from dedicated ECUs, the "Software as aProduct" (SaaP) concept has reinforced the core role of software in the entire lighting system.
Marelli's unique technological approach supports OTA (Over-the-Air) updates and continuous
deployment of new features for automotive lighting software, after the vehicle is in production.
Leveraging over 20 years of expertise in automotive lighting electronics, Marelli portfolio includes acomprehensive suite of control unit solutions for automotive lighting, ranging from basic lighting
controllers that meet distributed power supply systems, to centralized CAN communication
controllers that support adaptive matrix headlamps, to high-definition rendering controllers
represented by micro-LED and Digital Micromirror Device (DMD) technologies. This broad portfolio
meets customer demands for affordability, quality, and scalability. In particular, the know-how andsolutions of the company in terms of high-definition rendering algorithms applied to DMD and microLED have already been adopted by several global and Chinese premium brands.
Overall, with its solid software and hardware design foundation, Marelli provides robust support forthe design of innovative lighting solutions, in particular in the field of adaptive headlights. Marelli has
been leading the industry's development to high-definition adaptive headlight solutions up to 1.3
million pixels, for which the company provides both optical modules and electronic control modules.

Also, Marelli has been the first company to apply Digital Micromirror Device (DMD) technology toadaptive headlights.
In China, Marelli has built a complete localized R&D, design, and production system. On theproduction side, Marelli has devoted production facilities for electronic control units for lighting in
Guangzhou and Wuhu. On the R&D side, the company has centers in Shanghai and Wuhu to support
the development of lighting control units for Chinese and global market, while also closelycollaborating and sharing design resources with design centers in Europe. This enables the companyto quickly respond to market demands and provide customers with innovative, efficient andaffordable lighting controller system solutions.
Visitors to the Beijing International Automotive Exhibition will have the possibility to see andexperience the most advanced Marelli innovations in the lighting field at the company’s booth, W1W01, in the Temporary Hall.
