  • Publication number: 20150117043
    Abstract: Disclosed is a lamp unit including a plurality of light sources and a mechanism configured to adjust a reference position of an axis according to the light sources. A projection lens unit includes a first projection lens and a second projection lens. At least some of light emitted from a first light source passes through the first projection lens. At least some of light emitted from the second light source passes through the second projection lens. A first adjusting mechanism moves the first projection lens unit in parallel in left and right directions with respect to the first light source and the second light source. A second adjusting mechanism moves the projection lens unit in upward and downward directions which are orthogonal to the left and right directions, with respect to the first light source and the second light source.
