The previously optional MULTIBEAM LED is now the standard headlamp for the S-Class. As well as variable control of low and high beam, it also features Adaptive Highbeam Assist Plus. The optional DIGITAL LIGHT system enters series production for the first time at Mercedes-Benz. This allows completely new functions,
e.g. the projection of guidelines or warning symbols onto the road ahead.
In the MULTIBEAM LED headlamp, a light module with 84 LEDs arranged in three lines creates a grid in the form of a matrix. With this arrangement, not only the light distribution of the high beam but also that of the low beam is freely configurable and technically precise. MULTIBEAM LED therefore allows different light functions to actuate independently.
Digital Light: high-resolution light projection with new functions
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:
- 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.
 Owing to road traffic regulations, the availability and functions of these new assistance functions may be restricted on a market-specific basis.
