Abstract
An adaptive vehicle headlight is provided for being installed on a vehicle body for use. The adaptive vehicle headlight includes a light body, an optical lens, a driver, and a control unit. The optical lens, the driver, and the control unit are integrated into the light body. In practice, the optical lens can optionally include a light distributing member. The control unit can cause an operation of the driver according to a tilt angle of the vehicle body, such that the optical lens and/or the light distributing member are rotated to a predetermined angle, so as to produce an illumination pattern in a horizontal state.

An adaptive vehicle headlight for being installed on a vehicle body for use, comprising:
- a light body including a base, a rotating member and a light emitting unit, wherein the base has a carrying portion, the rotating member is configured to rotate relative to the base, and the light emitting unit is arranged on the carrying portion to emit an illumination light beam;
- an optical lens arranged in the light body to allow the illumination light beam to project outwardly so as to produce an illumination pattern in a horizontal state, wherein the optical lens is connected as a whole to the rotating member;
- a driver arranged in the light body to drive the rotating member;
- and
- a control unit arranged in the light body to cause an operation of the driver according to a tilt angle of the vehicle body, such that the rotating member and the optical lens synchronously rotate a predetermined angle to maintain the illumination pattern in the horizontal state;
- wherein the rotating member includes an outer frame portion, an inner frame portion and a wall portion, the outer frame portion and the inner frame portion are spaced apart from each other, the wall portion is connected between the outer frame portion and the inner frame portion, and the carrying portion is exposed from the wall portion;
- wherein the optical lens is fixed to the outer frame portion, the driver includes a coil structure and a magnetic body, and the coil structure and the magnetic body are disposed between the outer frame portion, the inner frame portion and the wall portion.
