Abstract (en)
In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a planar reflect surface (7) is arranged between the projection lens (6) and its focus (FL1) in such a way that the planar reflect surface (7) intersects the light axis (Z1-Z1) of the projection lens (6); a light shutout member (8) is arranged between the semiconductor light source (4) and the projection lens (6), the light shutout member (8) is provided with supplemental reflect surfaces (17-20) reflecting the light (L3) from the semiconductor light source (4) toward the shade (5). As a result, the light (L3) from the semiconductor light source (4) can be effectively used.
