The h-Digi microLED module, which is now in series production, is based on a new type of intelligent multipixel LED, which enables fully adaptive, dynamic headlight operation and image projection. Designed as an affordable technology it is being made available for a wider range of vehicles.
The h-Digi microLED is based on a matrix illumination system – featuring around 40,000 LED pixels (20,000 per lamp). This intelligent solution manages the LEDs selectively to create very flexible low-beam and high-beam light distributions, adapting to various driving situations.
It also provides dynamic curve light and very precise glare-free high beam block out zones, to avoid blinding oncoming drivers. In terms of safety, the Marelli h-Digi microLED can also project warnings or driver assistance images on the road, directly in the driver’s field of view. Other advantages include the extremely compact design and high energy efficiency.
The Marelli microLED system is based on ams OSRAM’s light source EVIYOS 2.0. Its combination with a special optical lens system and a new electronic control engineered by Marelli’s Automotive Lighting & Sensing division, enables the enhanced level of adaptability of the illumination field. This is the first time that LEDs with a size of 40 µm x 40 µm are introduced as pixel elements in vehicle headlamps.
With pixels smaller than 0,1 degree, the resolution of this illumination matrix system is 10 times more precise than conventional LED glare-free high beam systems, which are currently on the road. Two micro-LED options are available: an aspect ratio of 1:4, resulting in 25,600 pixels, or an aspect ratio of 1:3, providing 19,200 pixels per lamp.
The h-Digi microLED is Marelli’s second generation of high-resolution projection systems.
