Vehicular lamp unit and vehicular lamp

摘要

A vehicular lamp unit includes a projection lens disposed on an optical axis extending in a vehicular longitudinal direction; a light source disposed rearward of a rear side focal point of the projection lens; a reflector reflecting direct light from the light source forward towards the optical axis; a shade disposed between the projection lens and the light source such that the shade blocks a part of reflected light from the reflector and a part of the direct light from the light source to form a cut-off line of a light distribution pattern; a first reflective surface formed on a tip portion of the reflector such that the first reflective surface reflects a part of the direct light from the light source downward to the front of the shade; and a second reflective surface formed on the front of the shade and below the rear side focal point of the projection lens such that the second reflective surface reflects reflected light from the first reflective surface towards the projection lens so that upward directed radiated light is emitted from the projection lens. The second reflective surface includes a vertically divided upper-side second reflective surface and lower-side second reflective surface. Radiated light provided by the lower-side second reflective surface radiates above radiated light provided by the upper-side second reflective surface.
