Abstract
A vehicle headlamp includes a lamp outer case 4, a holding plate 12, a lamp unit 6, and an optical axis adjustment mechanism 16. The lamp outer case 4 includes a lamp housing 2 formed with an opening on at least one side thereof and a cover 3 covers the opening of the lamp housing 2. The holding plate 12 is pivotable in at least one of an up-down direction and a right-left direction. The lamp unit 6 is attached to the holding plate 12 and includes a light source 10b. The optical axis adjustment mechanism 16 is disposed below the lamp unit 6 and adjusts an optical axis direction of the lamp unit 6.
Claims23
A vehicle headlamp comprising:
- a lamp outer case including
- a lamp housing formed with an opening on at least one side thereof, and
- a cover that covers the opening of the lamp housing;
- a holding plate that is pivotable in at least one of an up-down direction and a right-left direction;
- a lamp unit that is attached to the holding plate and includes a light source;
- and
- an optical axis adjustment mechanism that is disposed below the lamp unit and adjusts an optical axis direction of the lamp unit;
- wherein
- the holding plate is pivotable in one of the up-down direction and the right-left direction,
- the optical axis adjustment mechanism includes a support plate that supports the holding plate so as to be pivotable in the one of the up-down direction and the right-left direction and that is pivotable in the other of the up-down direction and the right-left direction with respect to the lamp housing,
- when the holding plate is pivoted in the one of the up-down direction and the right-left direction, the optical axis direction is adjusted in the up-down direction or the right-left direction by the optical axis adjustment mechanism,
- when the support plate and the holding plate are integrally pivoted in the other of the up-down direction and the right-left direction, the optical axis direction is adjusted in the up-down direction or the right-left direction by the optical axis adjustment mechanism;
- and
- the light source is disposed above any part of the support plate.
