There is a vehicle headlamp in a multibeam mode comprising: a reflecting mirror
for reflecting light emitted from a discharge tube having a single light emitting
section; and a shield for blocking off light directly emitted forward and light
emitted to the lower part of the reflecting mirror out of the light emitted from
the discharge tube, wherein the headlamp includes a rotationally moving device
for three-dimensionally moving the light emitting section of the discharge tube
to any position of the reflecting mirror, which is suitable for low-beam or high-beam,
by eccentrically rotating the discharge tube to move back and forth; and a rotation
controller for controlling the rotation of the rotationally moving device. The
headlamp can be used in several beam modes using a conventional reflection mirror
and a discharge tube.
