Abstract:
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).
