1. A vehicle headlight comprising:
a housing having a body, a first end plate and a second end plate, and the body formed in a tubular shape having a first opening and a second opening facing the first opening, the first end plate having an outer surface, an inner surface and a third opening passing through the outer surface and the inner surface, the first end plate located adjacent the first opening of the body, the inner surface of the first end plate facing the second opening of the body, the second end plate having a fourth opening, X axis and Y axis substantially perpendicular to the X axis, and also having a fifth opening and a sixth opening, each of the fifth opening and the sixth opening being separated by the X axis and intersecting with the Y axis, the fourth opening of the second end plate intersecting with the X axis and the Y axis, and each of the fourth opening, the fifth opening and the sixth opening passing through the second end plate, the second end plate being located adjacent the second opening of the body, and the fourth opening of the second end plate facing the third opening of the first end plate of the housing; a light source unit having a semiconductor light source located adjacent the outer surface of the first end plate, and configured to emit light having a substantially white color tone substantially toward an intersection of the X axis and the Y axis of the second end plate of the housing via the third opening of the first end plate of the housing; a light deflecting device having a movable mirror and a torsion holder, and located adjacent the second end plate of the housing so as to cover the fourth opening of the second end plate, the torsion holder supporting the movable mirror from both directions of the X axis and the Y axis substantially toward the intersection of the X axis and the Y axis so that the movable mirror is configured to rotate with reference to the X axis and the Y axis, the movable mirror having a default position being located toward the third opening of the first end plate of the housing, and the movable mirror located substantially at the intersection of the X axis and the Y axis, the default position of the movable mirror being determined by a restoring force of the torsion holder and the movable mirror being substantially perpendicular to a light-emitting direction of the light having the substantially white color tone emitted from the light source unit at the default position of the movable mirror; an actuator located adjacent the light deflecting device, and configured to rotate the movable mirror in at least one direction of the X axis and the Y axis via the torsion holder during operation; a static mirror having at least one of a first reflection surface and a second reflection surface being located adjacent the inner surface of the first end plate of the housing so as to avoid blocking the third opening of the first end plate, the first reflection surface having an end line formed in a substantially spheroidal shape having a first focus and a second focus, the first focus of the first reflection surface being located substantially at the movable mirror, the second focus of the first reflection surface being located substantially at the fifth opening of the second end plate, the second reflection surface having an end line also formed in a substantially spheroidal shape having a first focus and a second focus, the first focus of the second reflection surface being located substantially at the movable mirror, and the second focus of the second reflection surface being located substantially at the fifth opening of the second end plate; and a controller having an operation unit, an actuator driver and a light source driver, the actuator driver configured to control the actuator, the light source driver configured to control the semiconductor light source, and the operation unit configured to control the actuator driver and the light source driver; wherein the operation unit associates the light having the substantially white color tone emitted from the light source unit with the movable mirror via the actuator driver, and thereby the light having the substantially white color tone is configured to be projected from at least one of the fifth opening and the sixth opening of the second end plate via the movable mirror, and at least one of the first reflection surface of the static mirror is configured to reflect the light toward the fifth opening of the second end plate and the second reflection surface of the static mirror is configured to reflect the light toward the sixth opening of the second end plate during operation. |
