US 2026/0098620 A1 · OPTICAL DEVICE AND VEHICLE INCLUDING THE SAME

Abstract

An optical device that deliberately allows a portion of light incident from a light source to leak and the light having leaked to be re-incident while forming a new optical path. The optical device includes a light source, a light guide disposed in front of the light source to guide light incident from the light source forward through total reflection, and a light emission lens forming a beam pattern using light incident from the light guide. The light guide includes a light incidence portion and an optical path portion forming an optical path for light incident on the light incidence portion. The optical path portion includes a first optical path portion having an opening therein to allow a portion of light incident to leak and a second optical path portion including a re-incidence surface on which light having leaked through the opening is incident.
