Zusammenfassung: | A vehicle lamp (18) is proposed, comprising a lamp unit (24) that includes a first light emitting unit, a second light emitting unit, and an optical system (30) that repeats a periodic motion and thus scans an exit beam from the first light emitting unit and an exit beam from the second light emitting unit; and a controlling unit (20) arranged to set an on period separately for each of the first light emitting unit and the second light emitting unit within one scan period in synchronization with the periodic motion and thus forms a light distribution pattern in which respective scan beams associated with the first light emitting unit and the second light emitting unit are combined, wherein the controlling unit (20) is arranged to vary the on period, within one scan period, of at least one of the first light emitting unit and the second light emitting unit and thus changes a luminous intensity distribution of the light distribution pattern. |
