VEHICLE LAMP

A vehicle lamp (18) is proposed, comprising a light source (28); an optical system (30) that repeats a periodic motion and thus scans an exit beam from the light source (28); and a controlling unit (20) for controlling the on/off of the light source (28) to form a predetermined light distribution pattern, wherein the controlling unit (20) is arranged to set a brightness of the light source (28) to no higher than a predetermined value in a partial time segment within one scan period and thus forms a non-illumination region in a region corresponding to the time segment, and when the non-illumination region is to be changed over to an illumination region, starts changing the non-illumination region over to the illumination region from one end and changes gradually toward another end of the non-illumination region in a widthwise direction of the vehicle.
