Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture which can emit light from a wide range of a wide light guide part with a small number of light sources while suppressing unevenness, and which can suppress formation of a dark spot by sufficiently passing light in an end part on the incident side.SOLUTION: A vehicular lighting fixture includes a light guide body which has an incident part in which light from light sources enters at an end part, and which guides the light by a light guide part extending from the incident part and emits the guided light from a surface along an extension direction of the light guide part. A plurality of light sources for emitting diffusion light are arranged side by side. The incident part includes: a plurality of convex parts provided opposing to each light source and for allowing the light from the light sources to enter and for refracting it in the direction along the extension direction of the light guide part; and a protrusion provided between the plurality of convex parts, and for internally reflecting the light from each light source and allowing it to be along the extension direction of the light guide part.SELECTED DRAWING: Figure 2
