Abstract

A vehicle lamp including: a light source; a light guiding member configured by elongated member with light transmitting properties, and has light from light source incident through one length direction end face and emits light from light source from an emission face running along length direction; plural prism portions provided on an opposite side of light guiding member from emission face, that are disposed in row along length direction, and reflect light from light source incident to light guiding member toward emission face; circular arc shaped section formed on emission face side of light guiding member, and is configured with circular arc shaped cross-section in a direction orthogonal to light guiding member length direction; and a polygonal shaped section is formed on the prism portion side of light guiding member, and is configured with a polygonal shaped cross-section in a direction orthogonal to light guiding member length direction.

Description

technical field [0001] The embodiments discussed herein relate to a lamp for a vehicle. Background technique [0002] Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2013-045662) discloses a vehicle lamp including a light guide lens (light guide member) extending in a direction inclined The LED as a light source is arranged so as to face the rear end portion and the front end portion of the light guide lens. Lens slices are arranged side by side along the length direction on the rear surface of the light guide lens. In this vehicular lamp, the light emitted from the LED on the rear side and entered into the light guide lens from the rear end of the light guide lens is internally reflected forward by the lens slice, and the light from the LED on the front side is After the light enters the light guide lens, the light is internally reflected forward by the lens slice. In addition, there is also a structure described in Patent Document 2 (JP 2013-04...
