摘要： A projector type vehicle headlamp (1) includes a metal supporting member (3) that has an upper surface (11a) to which a circuit board (2a) to which a light-emitting device (2) is mounted is mounted; a projection lens (4); a reflector (5) that reflects light (B1) of the light-emitting device (2) toward the vicinity of a rearward focal point (S1) of the projection lens (4); a driving source (46); and a movable shade (44) configured to be arranged near the rearward focal point (Sl) of the projection lens (4), or removed from near the rearward focal point (S1), by the driving source (46). The driving source (46) is provided in front of the metal supporting member (3), and a cooling fan (30) that faces a lower surface (11b) of the metal supporting member (3) is provided below the metal supporting member (3).

摘要： A lamp unit (210) includes: a projection lens (20) that radiates light from a light source (14); and a shade (110,120,130) interposed between the light source and the projection lens and for forming a light distribution pattern having a first cutoff line extending horizontally from a neighborhood of a center of the light distribution pattern and a second cutoff line extending upwardly from the neighborhood of the center. The shade includes a gradation forming portion for forming a gradation in the second cutoff line in the second cutoff line forming edge portion. The gradation is for making variations gradual in illumination in the portion of the second cutoff line than that in an area of the neighborhood of the center.

摘要： An optical unit (100) includes: a heat sink (130) that radiates heat from a light source; and a base portion (150) including a reflector mounting section (152), a lens mounting section (154) and a connecting section (156) connecting the reflector mounting section (152) and the lens mounting section (154). The base portion is configured such that the light from the light source is reflected by a reflector (110) mounted onto the reflector mounting section (152) and is incident onto a projection lens (102) mounted onto the lens mounting section (154). The heat sink (130) is exposed to a space surrounded by the lens mounting section (154), the connecting section (156) and the reflector mounting section (152).
