Vehicular lamp

Abstract

A vehicular lamp includes a light source disposed on an optical axis extending in a front-back direction of the vehicular lamp; and a reflector that reflects forward light from the light source. The reflector is formed by a translucent member including a plurality of optical elements disposed continuously in a radial direction of the optical axis. Each of the optical elements includes: a surface of incidence through which light from a light emission reference point in the light source is incident into the optical element and which refracts the light into a direction away from the optical axis, a reflective surface which internally reflects forward the light which is incident into the optical element through the surface of incidence, and a surface of emission through which the light internally reflected by the reflective surface is emitted forward from the optical element. The reflective surface of each of the optical elements is formed by a curved surface formed to allow generally an entirety of the light internally reflected by the reflective surface to reach the surface of emission of the optical element as substantially parallel light.
