Abstract

A light-emitting part for a vehicle having a light-emitting region is described. The light-emitting part includes an irradiation body which i) includes a dot-shaped light source and a planar plate-shaped light guide body that emits light from the dot-shaped light source, and ii) emits the light toward a front side of the light-emitting region. The light-emitting part includes a curved plate-shaped transmissive body disposed so that the light emitted from the irradiation body is transmitted through the curved plate-shaped transmissive body. The curved plate-shaped transmissive body includes portions which are separated from the planar plate-shaped light guide body by different gaps. Also included is a surface brightness adjusting portion which adjusts a brightness of an outer surface of the light-emitting region in response to a size of the gap and a distance from the dot-shaped light source.
