Controlling headlamp unit for vehicle involves reducing light density of light emissions from first source in region close to vehicle if second light source added and while second source is on

摘要

The method involves producing a first light function with a shorter range using a first light source (1) and producing a second light function with a longer range using a second light source (2). The light density of the light emissions from the first source in the region close to the vehicle is reduced if the second light source is added and remains reduced while the second source is on. AN Independent claim is also included for the following: (a) a headlamp unit for a vehicle.
