Motor vehicle headlamp with low-beam operation, uses lamp units containing one or more light-emitting diodes with some units providing direct lighting, some controlled-direction reflected lighting and others with reflected diffuse lighting

摘要

The headlamp (10) has multiple lamp units (20,40A,40B,60) each using light-emitting diodes (LED) as light sources. One unit (20) forms the low beam cutoff, another (40A,40B) forms the high intensity zone and the third unit (60) forms the diffusion region. The reflector profile for the intense unit directs light straight ahead and for the low beam unit directs light below the low beam cut-off.
