Definitions

  • the polka dot steps each have a convex semicircular cross-sectional shape, and are formed on the surface (rear surface) of the inner lens on the light source side.
  • Recesses having a concave semicircular cross-sectional shape are formed at positions of the outer surface of the inner lens corresponding to the polka dot steps.
  • the recesses have a circular shape smaller than that of the polka dot steps in the front view and are concave in the cross-sectional shape.
  • a vehicle lighting fixture includes: a light source configured to emit light; a reflector configured to reflect light emitted from the light source toward a first direction; and a light guide lens having a front surface and a rear surface, configured to receive from the rear surface the light reflected by the reflector and output the light from the front surface.
  • the light guide lens has a recess portion in the front surface, and a lens portion in the rear surface, the lens portion corresponding to the recess portion, and a part of the light condensed by the lens portion is totally reflected by the recess portion, so that a region corresponding to the recess portion is caused to output light with an intensity relatively smaller than that in a periphery thereof.
