Abstract

See full text

A projection-type headlamp producing a low-beam light distribution pattern having a cut-off line and which provides improved visibility for the driver of the vehicle with a reduced possibility of inflicting glare on drivers of oncoming vehicles. A low-beam light distribution pattern is synthesized from a base light distribution pattern, formed by a projection-type lamp unit, and a pair of additional light distribution patterns, formed by light reflected from a pair of additional reflectors provided on right and left sides of a lamp unit body. The additional light distribution patterns are superimposed on a horizontal cut-off line having a level difference within the base light distribution pattern. The contrast between the area above the horizontal cut-off line and the area below the horizontal cut-off line is accordingly reduced.
