Abstract
A lamp unit includes a first semiconductor light-emitting element that serves as a light source; a second semiconductor light-emitting element that serves as a light source; a support member that supports the first semiconductor light-emitting element and the second semiconductor light-emitting element; a first reflector provided above the first semiconductor light-emitting element, which reflects light radiated from the first semiconductor light-emitting element forward; a shade that blocks a portion of reflected light from the first reflector; a projection lens provided in front of the first reflector with the shade disposed therebetween, which forms a light distribution pattern with a cut-off line from light reflected by the first reflector; a positioning portion that positions the projection lens; and a second reflector provided below the second semiconductor light-emitting element, which reflects light radiated from the second semiconductor light-emitting element forward.
