| description | An object of the present invention is to control light distribution in a vehicle headlamp (1) of projection type so that light is distributed to a predetermined point while a light distribution pattern for overhead is transversely spread. The present invention includes a discharge lamp (2), a reflector (3), a projection lens (4), a shade (5), and a reflection member (6). At a window portion (12) of the shade, edges (13, 14, 15) are provided for forming cutoff lines CL1, CL2, and CL3. The reflection member (6) is disposed between the projection lens (4) and the shade (5). At the reflection member (6), recessed reflection surfaces (19, 20, 21) are provided for transversely spreading a light distribution pattern OSP for overhead sign. As a result, the present invention is capable of controlling light distribution so that light is distributed to a predetermined point in a state in which the light distribution pattern OSP for overhead sign is transversely spread. |
