ABSTRACT:
In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a shade (5) is arranged between the second focus (F2) of a first reflect surface (9) and a semiconductor light source (4), for cutting off a portion of the reflected light (L4) emitting from the semiconductor light source (4) and reflected by the first reflect surface (9), and using the remaining reflected light (L4) to form a predetermined distributed light pattern (P) having the cutoff lines (CL); a light shutout member (8) is provided with the fourth part (20) of the supplemental reflect surface for reflecting the light (L3) from the semiconductor light source (4) toward the shade (5); a through hole (24) is arranged on the shade (5) for the reflected light (L17) from the fourth part (20) of the supplemental reflect surface illuminating therethrough toward the planar reflect surface (7). As a result, as a distributed light pattern P4for a overhead sign, the light (L3) from the semiconductor light source (4) can be effectively used.
