Vehicle lamp unit and vehicle headlamp using the same

摘要

A vehicle lamp unit (1) includes a reflective surface (4) based on an ellipse, the reflective surface having a first focal point (F1) and a second focal point (F2); a semiconductor light source (6) of which a light emitting portion (10) is provided at the first focal point (F1) of the reflective surface (4) or a vicinity of the first focal point (F1); and a projection lens (7) that projects a reflected light that is a light emitted from the semiconductor light source (6) and reflected by the reflective surface (4) to outside. An emission direction of a maximum light emission intensity from among light intensities of the semiconductor light source (6) is inclined in a direction opposite to the projection lens (7) with respect to an optical axis of the projection lens (7).
