Abstract
An occupation space of a lamp including a mechanism for adjusting a reference position of an optical axis is reduced. The optical axis adjustment mechanism 17 adjusts a reference position of an optical axis of a projection lens through which at least some of the light emitted from the light source 21 passes. The optical axis adjustment mechanism 17 includes an actuator 71, an aiming screw 72 and a slider 73. The actuator 71 includes an electrically driven output shaft 71b which pivots the optical axis in a horizontal direction about a rotation axis B extending in a vertical direction. The slider 73 is disposed to be slidable along the rotation axis B. The aiming screw 72 slides the slider 73 according to its rotation so as to translate the optical axis in the vertical direction.
Claims15
A lamp mounted in a vehicle, comprising:
- a light source,
- a projection lens through which at least some of light emitted from the light source passes, and
- an optical axis adjustment mechanism configured to adjust a reference position of an optical axis of the projection lens,
- wherein the optical axis adjustment mechanism includes
- an actuator having an electrically driven output shaft which pivots the optical axis in a second direction intersecting with a first direction about a pivot axis extending in the first direction,
- a slider disposed to be slidable along the pivot axis, and
- an aiming screw configured to slide the slider according to rotation of the aiming screw so as to translate the optical axis in the first direction.
