In this first part, we present the Mercedes-Benz CLS lighting.
In the second part, next week, we will introduce Uwe Kostanzer, his strategy and his vision on lighting.
Lighting is becoming a complex system with the headlamp, several sensors and associated software. CLS light system is a good example.
The headlamps are produced by Automotive Lighting and the software was developed in a close relation between Mercedes-Benz and Automotive Lighting.
1) Description of CLS headlamp.
All the lighting functions are produced 71 LEDs and the LEDs for the driving beam-functions manufactured by Philips Lumileds (Altilon). Each individual LED can be controlled separately, which makes all the lighting functions available electron¬ically.
The total number of pieces is approximately 350 which is a huge number.
3 components are involved, 1 projector sourced by 2 LED modules and 2 reflectors sourced each by 1 LED module.
The adaptive cut-off is realized from the signal of a camera located at the rearview mirror area. The cut-off is in permanence enslaved to the bottom of oncoming front lights or preceding rear lights with a movement depending on the speed of the car and the environment.
