Light guiding lens and vehicle light

摘要

A light guiding lens (5) can be provided to increase the amount of light beams properly propagating through a corner section (curved section 52) and the following section (extension section 53) of the light guiding lens (5) as well as improving the design degree of freedom. The light guiding lens (5) can be disposed at an area out of an optical path for the light beams for forming a predetermined light distribution pattern. The light guiding lens (5) can include: a lens main body (51) extending in a vertical direction; a curved section (52) configured to be curved away from an optical axis of a light source (3) with respect to the lens main body (51); and an extension section (53) configured to extend from a distal end of the curved section (52) in a direction substantially perpendicular to an extending direction of the lens main body (51). The lens main body (51) can have a light incident surface (511) on which the light beams out of the optical path can be incident and a reflecting inner surface (512) configured to reflect the light beams entering the lens main body (51) through the light incident surface (511) toward the curved section (52) by internal reflection. At least one cut surface (522) can be formed on an outer peripheral surface of the curved section (52) with the cut surface (522) being capable of reflecting the light beams reflected by the reflecting inner surface (512) toward the extension section (53) by internal reflection.
