With its two projector modules, the new LED intelligent lighting system from Automotive Lighting on the Mercedes S-Class exceeds HID performance and adapts automatically to the driving conditions. Additionally, it adapts automatically to weather conditions, traffic situation, road environment and driving speed.
The main components of the headlamp are two all-LED projector modules, both conceived to emit the low beam and working together to distribute the light and form the low beam cutoff line. The “base” light module is powered in its basic function by 8 LEDs for low beam and provides wide road illumination creating a broad carpet of light. This module provides the horizontal portion of the cutoff. Additionally, it supports with another 4 LEDs the high beam of the second module: the swiveling adaptive module. Powered by 4 LEDs, this module produces the asymmetric portion of the cutoff line and guarantees a 145-metre low beam range. Furthermore, it implements the adaptive light distribution: For example, the motorway light is activated when the constant driving speed exceeds 90 km/h.
Another mentionable function of this module is the curve light: Ranging from 15° outward and 7° inwardly, it illuminates the course of the road in accord with the driving speed, the yaw rate and the steering angle. The Adaptive High Beam Assistant Plus function provides the glare free high beam allowing the use of high beam without dazzling the preceding or oncoming traffic. Furthermore, the detected pedestrians are lighted up by the spot marking light. All adaptive light functions are activated when the light switch is in the automatic mode.
Altogether, both modules of this all LED intelligent light system produce 1000 lumens in the low beam pattern. Their correlated colour temperature is 5500K – 6000K, and the CO 2 emission is only around 1 g/km.
