Actual Designs of Automotive Front Lighting Systems

After a period with improvements in the low beam area like dynamic curve light or motorway light, the special advantages of LEDs as light sources are now used to realize new functionalities in the high beam area. The “Glare-free High Beam” offers the driver a illumination of the street and the surrounding comparable to the known high beam, but does not glare other road users. To use this functionality in the car, a camera system analyzing the traffic situation is necessary. The glare-free high beam is realized as an optical or opto-mechanical system and can be based on reflection or projection type systems. The challenge of the optical system is to create on one hand vertical cutoffs for the shadows around other cars and on the other hand a homogeneous light distribution for the illumination of the scenery for the driver.
