Lamp unit of vehicular headlamp

A lamp unit of a vehicular headlamp comprising:

• a projection lens with an optical axis;
• a light source;
• a first reflector that reflects light from the light source so as to collect such light on or near the optical axis;
• and
• a shade positioned between the light source and the projection lens so as to extend along a direction of the optical axis,
• wherein the shade shields part of the light reflected by the first reflector and the shade comprises:
• a shielding surface extending rearward from a front end of the shade, where the shade is positioned near a rearward focal point of the projection lens, wherein the shielding surface serves as a second reflector that reflects light from the first reflector toward the projection lens, and
• a transparent portion formed on part of the second reflector such that part of the light reflected by the first reflector passes downward of the rearward focal point of the projection lens and is then incident to the projection lens.
