Abstract:
The objective of the invention is to provide a vehicular light equipped with an odd-shaped lens wherein light distribution loss has been suppressed. This vehicular light is equipped with: a light source unit comprising at least five light-emitting chips disposed horizontally; and an odd-shaped lens having a convex entry surface on the light source unit side and a convex exit surface in the direction leaving from the light source unit, wherein the entry surface comprises a free-form curved surface whereof the horizontal curvature radius increases gradually from the lens optical axis Z in the outward direction.
