Abstract:
The light distribution of a vehicle headlamp can be changed between various modes, including a basic mode and a motorway mode. In the basic mode, shaded region changeover means block a high light intensity region, and deflection control means controls a lamp optical axis Lx to a straight travel direction. In the motorway mode, the shaded region changeover means does not block the high light intensity region, and the deflection control means controls deflection of the lamp optical axis to a host vehicle lane side. A light distribution in which the high light intensity region faces a far distance ahead of the host vehicle lane can be obtained, and the host vehicle lane is brightly illuminated without dazzling a driver of a preceding vehicle or an oncoming vehicle. Accordingly, illumination suited to the motorway mode during high speed and medium speed travel can be achieved.
