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 for reflecting direct light from the light source forward towards the optical axis; an additional reflector disposed between the projection lens and the light source; and a shade portion disposed on the front end edge of the upper surface of the additional reflector. The additional reflector includes a flat upper surface extending rearward along the optical axis from a front end edge positioned in the vicinity of the rear side focal point of the projection lens that reflects a part of the reflected light from the reflector towards the projection lens. The shade portion forms a cut-off line of a light distribution pattern by blocking a part of the reflected light from the reflector and a part of the direct light from the light source. |
