New 2021 Mercedes S Class Digital Light Explained
In each headlamp, Digital Light has a light module with three extremely powerful LEDs whose light is refracted and directed by 1.3 million micro-mirrors. The resolution is therefore more than 2.6 million pixels per vehicle. The micro-mirrors occupy the same area as a thumbnail. A control unit with a powerful graphic processor uses an HDMI-like connection to generate a continuous video stream to the mirrors. Digital Light therefore uses the technology of video projectors. This innovative headlamp in the S-Class can be recognised by its concave lens, the lettering and shining blue floor facing.
The beam divided into 1.3 million pixels makes absolutely precise light distribution possible. It makes Highbeam Assist over 100 times more precise then 84-pixel light when excluding oncoming traffic or road signs from the light beam. Light/shadow graduations and the light distribution of all the other adaptive light functions are also realised with considerably more precision, optimising illumination by e.g. fog light, motorway light or city light.
The new assistance functions are also revolutionary, however[1]:
Warning of recognised roadworks by projecting an excavator symbol onto the road surface
Aiming a spotlight at pedestrians detected at the roadside as a warning
Traffic lights, stop signs or no-entry signs are pointed out by projecting a warning symbol onto the road surface
Assistance on narrow road lanes (roadworks) by projecting guidelines onto the road surface
The topographic light is another new function. This takes hills into account on the basis of navigation maps, especially crests and depressions: when cresting a hill, for example, the headlamp does not shine upwards but is pivoted down parallel to the road surface. In depressions the light beam is raised to maintain the desired range.
DIGITAL LIGHT welcomes and says farewell to the driver with a special light show.
[1] Owing to road traffic regulations, the availability and functions of these new assistance functions may be restricted on a market-specific basis.
