The purpose of the present invention is to provide a vehicular lamp which creates light directed upward using a reflector that allows the light incident below the lower end of the lens to exit upward through a lens and which minimizes the uneven light distribution of the created light distribution pattern. The vehicular lamp according to the present invention includes: a semiconductor light source unit (20) including a light-emitting chip (21); a horizontally long lens (30) disposed in front of the light source unit (20); and a reflector (40) positioned between the lens (30) and light source unit (40) and disposed below the light-emitting chip (21) along a vertical direction. The reflector (40) includes a reflection surface (41) for creating a plurality of virtual focal points intersecting a vertical axis passing through the light emitting center O of the light-emitting chip (21). The distribution of light from the reflection surface (41) is controlled so that light is emitted from a light emitting surface (32) vertically below the optical axis Z of the lens (30). The lens (30) is formed such that, when a point light source is assumed on the optical axis Z, first direct light LM on the optical axis Z emitted from the point light source is distributed upward from the light emitting surface (32).

A light beam adjusting device performs a process on at least two kinds of light beams in combination. Through this light beam adjusting device, a part of a first light beam is emitted from a first light exit face and another part thereof may be emitted from a second light exit face. Similarly, a part of the second light beam is also emitted from the first light exit face, and another part thereof may be emitted from the second light exit face. In this way, regardless of whether the first light beam is turned on or the second light beam is turned on, the light adjusted by the light beam adjusting device can be simultaneously emitted from the first light exit face and the second light exit face.

A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.
