<P>PROBLEM TO BE SOLVED: To restrain degradation of illuminance in an irradiation area at swivel operation, even while a light-emitting element array capable of omitting a swivel mechanism is used as a light source. <P>SOLUTION: Within an irradiation range PA including a plurality of partial areas L1 to L13, given irradiation areas are formed by irradiation of light by a plurality of light sources for the headlight arranged in a vehicle. In carrying out swiveling movement control in a given irradiation area within the irradiation range PA, differences of illuminance between adjacent partial areas included in the irradiation area are to be changed before and after the swivel movement. <P>COPYRIGHT: (C)2013,JPO&INPIT |
