Abstract
A vehicle lighting unit can use a light guiding body, and prevent light loss due to the internal reflection of light at the light exiting surface as a result of being guided through the light guiding body. The vehicle lighting unit can include: a light source; a projection lens; and a light guiding body to collect light from the light source near a rear side focal point of the projection lens so as to guide the light to the projection lens. The light guiding body can include a first optical surface that can serve as a light exiting surface through which the light from the light source guided through the light guiding body can exit. The projection lens can include the first optical surface, a second optical surface, and a third optical surface, and be configured to have the rear side focal point located behind the first optical surface.
