Definitions

  • the present invention relates to a vehicle lighting fixture.
  • vehicle lighting fixtures that are to be mounted on a vehicle, and can include a light source, a reflector configured to reflect light emitted from the light source and a light guide lens configured to receive from its rear side the light reflected by the reflector and output the light from its front side (for example, see JP 3180180 B ).
  • JP 3180180 B discloses a vehicle lighting fixture having a lamp chamber in which the light source is disposed and which has a front opening that is covered with an outer lens located outside and an inner lens located inside.
  • a group of convex fisheye steps and a group of concave fisheye steps are formed in the outer lens, and polka dot steps having a circular front shape are formed in the inner lens.
  • 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 three-dimensional feeling is emphasized by the difference between the appearance of the inside of the light chamber which is visible through the group of the convex fisheye steps and the appearance of the inside of the light chamber which is visible through the group of the concave fisheye steps.
  • the parallel light fluxes are refracted so as to converge.
  • a ring-shaped dark region having no transmitted light rays is generated in the peripheral edge portion of the polka dot step, and therefore, when the ring-shaped dark region is viewed through the outer lens, the stereoscopic effect described above can be emphasized more.
  • CN 209101211 A discloses an automobile tail lamp.
  • the automobile tail lamp comprises a bottom shell, a lampshade, an optical assembly and an automobile lamp inner accessory.
  • An automobile lamp inner accessory of the automobile tail lamp comprises a transparent part and a diffusion part. Point-shaped light equalizing structures which are distributed in an array mode are evenly arranged on the transparent portion of the automobile lamp inner accessory and used for refracting incident light and then emitting the light out to form a dot matrix light emitting decoration effect, and the diffusion portion of the automobile lamp inner accessory is used for diffusing light emitted by the optical assembly to form a uniform light emitting effect.
  • the dot-shaped light uniformizing structure of the automobile lamp inner accessory is adopted, so that the transparent part achieves the decorative effect of dot matrix light emitting based on an existing light source.
